Objective To explore the situation and causes of misdiagnosed hypoglycemia in China so as to develop some strategies for reducing misdiagnosis.Methods We searched CBMdisc, CMCC, CJFD and VIP (Jan. 1994-Dec. 2003). All the publisled studies about the misdiagnosis of hypoglycemia were collected to analyse their classifications and causes.Results A total of 172 studies involving 1 478 patients met the inclusion criteria. The studies were either case reports or clinical reviews. The 1 478 cases were misdiagnosed as 31 sorts of diseases, mainly including stroke (71.18%), transient ischemia attack (4.87%), epilepsy (4.13%) and hepatic coma (2.64%) . The causes of misdiagnosis could be classified into 14 categories, including complex manifestations of hypoglycemia (29.07%), lack of knowledge of hypoglycemic encephalopathy (16.44%), insufficient medical history collection (10.21%) and interference of compound diseases (9.86%) etc..Conclusions The misdiagnosis of hypoglycemia is mainly caused by the poor professional skills of doctors or their lack of responsibility, and poor patient management, especially when hypoglycemia are manifested by brain disability.
Objective We searched for evidence on mycophenolate mofetil(MMF) as a treatment for patients with diffuse proliferative lupus nephritis. Methods We attempted to find the current best evidence by searching The Cochrane Library(Issue 4, 2005), MEDLINE(1990 to June 2007), CMB(1980 to December 2006), CNKI(1979 to October 2007). We critically appraised the available evidence. Results Four systematic reviews and 6 randomized controlled trials of high quality were available. MMF and prednisolone were found to be an effective continuous induction-maintenance treatment for diffuse proliferative lupus nephritis. MMF was associated with less drug toxicity. Conclusion Given the current evidence and our clinical experience, and considering the patient and the values and preferences of his family,MMF was given at 1 g daily in combination with steroids at the beginning. No obvious adverse effects occurred during 3 months of follow-up.
OBJECTIVE In order to reduce the complication of the transposition of superficial cervical artery skin flap for the repair of neck defect, the method of pre-expanded skin flap was designed, and its clinical result was observed. METHODS From March 1995 to October 1997, 12 cases with cicatricial contracture of the neck were treated by the following methods, preexpanded superficial cervical artery skin flap, and then transposed it for the reconstruction the cervical scar after burns. There were 8 males and 4 females and the age ranged from 6 to 32 years. A maximal size of flap was 35 cm x 14 cm and a minimal size was 16 cm x 7 cm. RESULTS All the flaps were survived except one, which partial necrosis occurred in the tip. Postoperative follow-up for 6 months to 3 years showed that the physiological angle of cervico-mandibular angle was recovered and the appearance of flap was satisfactory without swelling and contracture. CONCLUSION The preexpanded superficial cervical artery skin flap has many advantages, and it is particularly suitable for reconstruction of severe cervical contracture after extensive burns.
Objectives To assess the quality of clinical practice guidelines for primary hepatic carcinoma published in 2016 and 2017 in China. Methods CNKI, WanFang Data, CBM and VIP databases were searched for clinical practice guidelines for primary hepatic carcinoma in China. The search date was from Jan. 1st, 2016 to Jan. 1st, 2018.

Conclusions The quality of clinical practice guidelines for primary hepatic carcinoma in China is relative high, of which the recommendations are of great value in clinical practice, yet still required to be improved in some ways.
ObjectiveTo explore Nursing Effect about patients' Accelerated Rehabilitation Surgery after Thoracoscopic Esophageal CarcinomaMethodsContinuous collection of 90 patients with thoracoscopic esophageal cancer from March 2017 to 2018 in this hospital, of which 45 patients in the control group were given routine care, and 45 patients in the experimental group were given individualized care. Analysis of nursing satisfaction and gastrointestinal function in two groups.ResultsThe satisfaction and gastrointestinal function of the two groups of patients were analyzed.. The average bowel sound recovery time and anal exhaust time were significantly shorter in the experimental group(31.25 ± 2.25 H, 50.12 ± 1.47 H) than in the control group(45.26 ± 2.17 H, 67.36 ± 1.06 H)(P = 0.028, P = 0.030). The incidence of adverse reactions was significantly lower in the experimental group(4.44 %) than in the control group(17.77 %)(P = 0.012), Nursing satisfaction was significantly higher in the experimental group(97.78 %) than in the control group(80%)(P = 0.007), Average hospitalization days and hospitalization costs in the experimental group(12.5±2.8d,9823±720¥),They were all significantly shorter than the control group16.3±3.4d,1378±790¥)(P =0.023, P =0.036）.ConclusionThe accelerated rehabilitation surgical care of patients with thoracoscopic esophageal cancer during perioperative period can help patients to accelerate recovery by promoting the recovery of gastrointestinal energy.
ObjectiveTo explore the effects of different concentrations of sevoflurane on hyperoxia-induced lung injury in rat.MethodsThe 72 SD rats were randomly divided into control group C (n=12); sevoflurane inhalation group S, group S contains 5 subgroups (n=12) S0, S1.0, S1.5, S2.0, S2.5. Group C wasn’t given any treatment, rats in group S were inhaled 95% oxygen for 48 hours to establish a hyperoxia-induced lung injury model. then rats in each subgroup inhaled sevoflurane at different concentrations of 0%, 1.0%, 1.5%, 2.0% and 2.5% for 1 h respectively, rats in group C were breathe air freely. At the two time points which include inhaled 95% oxygen for 48 hours, and sevoflurane was inhaled for 1 h, blood was collected by the abdominal aorta, then arterial blood was used for blood gas analysis; using enzyme linked immunosorbent assay for the detection of serum tumor necrosis factor (TNF) -α and interleukin (IL) -8 and IL-6 concentration; HE staining was carried out in the right lung, and the pathological changes of lung tissue were observed under light microscope; Wet to dry ratio (W/D) of the left lung was taken.ResultsAfter inhalation of 95% oxygen for 48 hours (T1): compared with the group C, group S of arterial blood gas results suggested that the PaO2 value decreased, PaCO2 value increased. The degree of lung tissue injury and the pathological score, TNF-α, IL-8 and IL-6, W/D content increased significantly (P < 0.05), there was no significant difference between the S0 to S2.5 groups; After treatment with sevoflurane for 1 h (T2): compared with the group C, group S of arterial blood gas results suggested that the PaO2 value decreased, PaCO2 value increased. the degree of lung tissue injury and the pathological score, TNF-α, IL-8 and IL-6, W/D content increased significantly (P < 0.05); Compared with before sevoflurane treatment, the PaO2 value increased, PaCO2 value decreased, TNF-α, IL-8 and IL-6, W/D content decreased, pathological score decreased in group S1.0 to S2.5 (P <0.05), but there was no significant difference in group S0; After treatment with sevoflurane, compared with S2.0 group, the PaO2 value decreased, PaCO2 value increased, TNF-, IL-8 and IL-6, W/D content increased, pathological score increased in the group S1.0 and S1.5 (P < 0.05), but there was no significant difference in group S2.5.ConclusionSevoflurane can effectively reduce the degree of lung injury caused by hyperoxia in rats especially when the concentration is 2%.
ObjectivesTo understand the current situation of the nosocomial infection management system in maternal and child health care institutions at all levels in Sichuan province, and provide a feasible policy basis for strengthening the nosocomial infection management.MethodsThe expert group members of Sichuan Maternal and Child Health Association Academy Association designed a unified questionnaire, and distributed the questionnaire through “Questionnaire Star” to carry out on-site online survey.ResultsA total of 159 maternal and child health care institutions participated in the survey. Most secondary and below maternal and child health care institutions had not set up professional hospital infection monitoring system. A few secondary and below maternal and child health care institutions did not independently set up a hospital infection management committee, hospital infection management department, full-time hospital infection department head, the inspection team of infection control, monitoring system, and nosocomial infection management system and special supervision had not been established in special departments. There were statistical differences in some jobs in the construction of nosocomial infection management system in different levels of maternal and child health care institutions (P<0.05).ConclusionsThe organizational system construction of hospital infection managemen are at a low level in the second level and below maternal and child health care institutions in Sichuan province. The tertiary maternal and child health care institutions should give full play to the leading role in promoting the standard construction of nosocomial infection management system of maternal and child health care institutions in Sichuan province, and carry out nosocomial infection management of maternal and child health care institutions orderly.
ObjectiveTo investigate effects of high expression of miR-499a-5p on lung injury in rats with acute respiratory distress syndrome (ARDS) by targeting matrix metallopeptidase-16 (MMP-16).MethodsThe experiment set up sham operation group, model group, miR-499a-5p mimic group, MMP-16 group, miR-499a-5p mimic+MMP-16 group, D-ribofuranosylbenzimidazole (DRB, Nrf2 signaling pathway inhibitor) group, miR-499a-5p mimic+DRB group. A rat model of ARDS was constructed by cecal puncture. One hour before surgery, the transfection complex (50 μL) was injected into the trachea with a micro-syringe. DRB (5 mg/kg) was intraperitoneally injected 30 min before surgery. The expression levels of miR-499a-5p and MMP-16 in lung tissue were detected by RT-qPCR; Alveolar type Ⅱ epithelial cells of model group rats were separated and MMP-16 3 'UTR WT and MUT luciferase report plasmid were transfected into alveolar type Ⅱ epithelial cells with miR-499 respectively to verify the targeting relationship between miR-499 and MMP-16; the targeted relationship was verified by the dual luciferase reporter gene; lung injury was observed by hematoxylin-eosin staining; The level of inflammatory factors in bronchoalveolar lavage fluid (BALF) and the level of oxidative stress in lung tissue were detected by enzyme-linked immunosorbent assay; The expression levels of NAD(P)H: quinone oxidoreductase 1 (NQO1), heme oxygenase (HO)-1, and nuclear factor-erythroid 2-related factor 2 (Nrf2) proteins in lung tissues were analyzed by Western blotting.ResultsmiR-499a-5p was down-regulated in the lungs of ARDS model rats (P<0.01), while MMP-16 was highly expressed (P<0.01); miR-499a-5p and MMP-16 3'UTR regions had binding sites, and miR-499a-5p directly targeted negative regulation of MMP-16 expression (P<0.01); overexpression of miR-499a-5p significantly reduced the right lung wet-to-dry weight ratio in the ARDS rats (P<0.05), reduced lung tissue damage (P<0.01), and reduced tumor necrosis factor α, interleukin (IL)-1β and IL-6 levels in BALF (P<0.01), decreased malondialdehyde and myeloperoxidase levels in lung tissue, increased total anti-oxidant capacity (P<0.01), and up-regulated NQO1, HO-1, Nrf2 protein expression in lung tissue (P<0.01). However, this phenomenon was significantly reversed after the addition of MMP-16 and DRB.ConclusionOverexpression of miR-499a-5p attenuates lung injury in rats with ARDS by targeting negative regulation of MMP-16 via activating the Nrf2 signaling pathway.
Objective To explore the secondary surgical reconstruction for orbital bone deformities accompanied with canthus dislocation after trauma. Methods From June 1998 to July 2007, 37 patients with secondary orbital bone fracture deformity accompanied with medial or lateral canthal l igament dislocation posttraumatically were treated, among whom there were 22 males and 15 females, aged 13-46 years old (21 on average). There were 29 cases of traffic accident, 6 of boxinginjury and 2 of beating injury by sticks. The latest reconstruction was performed on these 37 cases during 3 months to 8 years after injuries. There were 11 cases of orbital maxillary zygoma (OMZ) fracture, 15 of naso-orbito-ethmoid (NOE) fracture, 8 of OMZ and NOE fracture and 3 of frontal fracture. There were 31 patients who were reconstructed for the first time and 6 for the second time. Typical bicoronal and subcill iary incisions and intro-oral approach were employed to expose all the fractured sites. According to the fractured position and the degree of deformity and dislocation, the orbito-zygomatic fracture was repositioned after osteotomy and rigid fixation, or the heaved fragments were trimmed with a burr and the depressed fragments were filled with autogenous bone such as il ium, cranial outer table or Medpor in order to reconstruct orbital wall framework; the orbital walls were repaired to correct the enophthalmos with autogeneous bone or Medpor after the herniated orbital contents were released. The medial canthal l igament was anchored superior-posteriorly to the lacrimal fossa with transnasal wires fixation or fixed with titanium mini plates and nails. Results The 36 patients’ incisions obtained heal ing by first intention after the operation, and 1 case failed because of wound infection from maxillary sinusitis. There were 24 patients who were cured successfully with facial appearance and function improved significantly. During the follow-up for 3-6 months, no compl ication was found such as dislocation of the implant, rejection and infection. Two patients still showed sl ight enophthalmos while 3 patients with canthus dislocation regained improved appearances but not satisfactory. At 6 months after operation, the CT scan conducted in 3 patients with autogenous bone and Medpor grafting showed all fractures were fixed rigidly. Conclusion Surgical reduction combined with bone grafting is a satisfactory method for the correction of secondary orbital bone deformity, and the repair of canthus dislocation and correction of enophthalmos should be considered at the same time. An ideal result could be achieved only through all-round consideration and comprehensive treatment.
Objective To evaluate the efficacy and clinical significance of bipolar radiofrequency ablation in the treatment of left ventricular aneurysm with ventricular arrhythmias guided by CARTO mapping system. Methods From September 2009 to December 2015, 56 patients with ventricular aneurysm following myocardial infarction were enrolled. All patients suffered different levels of angina pectoris symptoms evaluated by Holter (the frequencies of ventricular arrhythmias more than 3 000 per day). They were divided into two groups according to random ballot and preoperative communication with patients' family members: a bipolar radiofrequency ablation group (n=28, 20 males, 8 females, mean age of 61.21±1.28 years) receiving off-pump coronary artery bypass grafting (OPCABG), ventricular aneurysm surgery combined with bipolar radiofrequency ablation, and a non-bipolar radiofrequency ablation group (n=28, 22 males, 6 females, mean age of 57.46±1.30 years) receiving OPCABG and single ventricular aneurysm surgery. The grade of cardiac function and ventricular arrhythmia was compared between the two groups during pre-operation, discharge and follow-up. Results All patients were discharged successfully. There was no in-hospital death in both two groups. One patient in the non-radiofrequency group had cerebral infarction. All patients were re-checked with Holter before discharge and the frequency of ventricular arrhythmias significantly decreased compared to that of pre-operation in both groups, and was more significant in bipolar radiofrequency ablation group (1 197.00±248.20 times/24 h vs. 1 961.00±232.90 times/24 h, P<0.05). There was significant difference in duration of mechanical ventilation and ICU stay between the two groups (P<0.05). The left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD) and left ventricular end-systolic diameter (LVESD) significantly improved (P<0.05) after operation in both groups. Conclusion The clinical efficacy of bipolar radiofrequency ablation in the treatment of ventricular aneurysm with ventricular arrhythmia guided by CARTO mapping is safe and effective, but its long-term outcomes still need further follow-up.
