ObjectiveTo explore the early diagnosis and treatment of acute non-tumor perforation of the back wall of ascending colon. MethodsWe retrospectively analyzed the clinical data of 17 patients with acute non-tumor perforation of the back wall of ascending colon treated between July 2007 and April 2014 in our hospital. Among them, 8 patients who underwent perforation repair combined with abdominal cavity drainage were regarded as the experimental group, and the other 9 patients who underwent operation of right hemicolectomy (or ascending colon resection) were designated as the control group. Clinical indexes and biochemical indexes of both the two groups were compared and analyzed. ResultsAll patients were cured. The operation time[(74.20±12.45), (120.23±15.20) minutes; t=-3.224, P<0.001], the intraoperative blood loss[(40.24±12.20), (80.69±18.98) mL; t=-4.114, P<0.001], the postoperative anal exhaust[(75.62±6.56), (84.54±7.82) hours; t=1.108, P=0.037], the medical expenses[(18.2±5.7) thousand yuan, (26.5±8.3) thousand yuan; t=-5.556, P<0.001], and the hypersensitive C-reaction protein on the third day after operation[(89.45±8.98), (99.85±10.78) mg/L; t=-3.004, P=0.029] in the experimental group and the control group all had significant differences. There was no significant difference between the two groups in the hospital stay time[(9.80±3.16), (9.81±3.20) days; t=1.501, P=0.080]. There was one case of incision infection in the experimental group and one case of fat liquefaction of incision in the control group, and both of them were cured after treatment. ConclusionThe early abdominal sign of perforation of the back wall of ascending colon is not obvious, which can easily lead to misdiagnosis as acute appendicitis. Early diagnosis mainly depends on the clinical symptom, vital sign, blood routine examination and CT examination. Among them, CT findings of gaseous sign behind peritoneum is a definite diagnosis, and operation should be arranged as early as possible. Perforation repair combined with abdominal cavity drainage is preferred due to its advantages of being simple, saving time, less bleeding and lighter traumatic reaction.
ObjectiveTo evaluate the relationship between some clinical laboratory tests, such as levels of fasting insulin (FINS), triglyceride (TG) and total cholesterol (TC), and benign prostatic hyperplasia (BPH). MethodsA total of 146 male patients were included in this study. All the subjects were from the clinic of West China Hospital and Sichuan Cancer Hospital from January 2012 to July 2013. Serum FINS, TG, TC and prostate specific antigen (PSA) were tested, respectively. Prostate volume (PV) was measured by ultrasound. ResultsFINS, PAS and annual prostate growth rate increased significantly in the large PV group compared with the small PV group (P<0.01). There was no significant association of PV with body mass index and other laboratory tests like serum TC and TG. PV and annual prostate growth rate increased significantly in the group of high FINS level compared with the group of low FINS level (P<0.01). PV was positively correlated with FINS (r=0.159, P<0.05); and annual prostate growth rate was positively correlated with FINS (r=0.201, P<0.05). ConclusionHyperinsulinism may play an important role in the pathogenesis of BPA.
ObjectiveTo evaluate the effects of sentinel lymph node biopsy following total mastectomy on immunologic function and prognosis for patients with early breast cancer. MethodsTwo hundred and eleven patients with early breast cancer were entered in this study. In all these cases, the results of sentinel lymph node biopsy were negative. These patients were randomly divided into control group and research group. In 86 cases of control group, the sentinel lymph node biopsy and axillary lymph node dissection following total mastectomy was performed. In 125 cases of research group, the sentinel lymph node biopsy following total mastectomy was performed. The injury of shoulder joint function was analyzed in one year after surgery. The changes of T cell subsets and IL-2 level were detected in the patients respectively on the first day before operation, the second week after operation, and the fourth week after operation. Postoperative fatality rate and postoperative recurrence rate were also observed in two groups. Results①The points of shoulder joint function in the control group and the research group were 72.7±6.5 and 93.5±8.2 respectively, there was an obvious difference (P < 0.05).②The injury degree of shoulder joint function in the research group was significantly lower than that in the control group (P < 0.01).③Compared with the control group, the changes of T cell subsets and the IL-2 level had no significant differences in the research group on day 1 before operation and on week 2 after operation (P > 0.05). On the fourth week after surgery, the CD4+, CD4+/CD8+, and IL-2 level in the research group were obviously higher than those in the control group (P < 0.05). However, the percentage of CD8+ T cell in the research group was significantly lower than that in the control group (P < 0.05).④There were no significant differences for postoperative fatality rate and postoperative recurrence rate between two groups (P > 0.05). ConclusionsSentinel lymph node biopsy for patients with early breast cancer is safe and reliable. With respect to conventional axillary lymph node dissection, it could improve immune function and quality of life after surgery in patients with early breast cancer.
ObjectiveTo investigate the effectiveness of nasolabial island pedicled flap in repairing mouth floor defects. MethodsBetween July 2010 and July 2013, 13 cases of mouth floor defects were repaired with nasolabial island pedicled flap. There were 7 males and 6 females, aged 36-73 years (mean, 58 years). Defects were caused by lesion resection, including 4 cases of leukoplakias, 2 cases of erythema, 1 case of mucoepidermoid carcinoma, 2 cases of the month floor cancer, and 4 cases of tongue cancer. The locations of defects were the mouth floor in 5 cases, the mouth floor and tongue body in 6 cases, and the mouth floor and gingival in 2 cases; the mucosa and submucosa were involved in 6 cases, and the sublingual gland, tongue muscle or alveolar process in 7 cases. The size of defect was 1-4 cm. The size of the flaps ranged from 4.5 cm×2.0 cm to 6.5 cm ×3.5 cm. ResultsThe operation was successfully performed in all patients; the flaps survived; and the primary healing of incisions at donor site and recipient site were obtained. Thirteen patients were followed up 5-24 months (mean, 11 months). No tumor recurrence was observed; the patients had normal functions of eating, swallowing, and speech. The facial appearance was satisfactory. No obvious deformity was observed at donor sites. ConclusionThe nasolabial island pedicled flap is fit for repairing small or middle sized defects of the mouth floor, and it has the advantages of flexible flap transplantation, less injury at donor site, easy operation, and high flap survival rate.
ObjectiveTo investigate the risk or protective factors for systemic embolism (SE) in patients undergoing bioprosthetic mitral valve replacement (MVR). Methods Between October 2002 and March 2013, a total of 146 patients underwent bioprosthetic MVR. There were 78 females and 68 males with mean age of 66.23±5.17 years. The primary reason of mitral valve disease was mitral valve degeneration or mitral valve leaflet prolapse in 40 patients, rheumatic heart valve disease in 101 patients, ischemic heart disease in 3 patients, infectious endocarditis in 1 patient, and mechanical peri-valvular leak in 1 patient. All patients were given anticoagulation therapy with warfarin for 3 months. Thereafter, antithrombotic medication was prescribed according to the surgeon's preference. The patients were followed up by telephone or mail for postoperative condition and SE events. ResultsSixteen (10.96%) patients developed SE events, including cerebral infarction in 13 cases, transient ischemic attack (TIA) in 2 cases and spleen infarction in 1 case. A total of 16 patients died during follow-up. The 1-year, 3-year, 5-year and 10-year cumulative survival rate after surgery was 95.2%, 93.6%, 92.5% and 88.3% respectively. Patients with SE events had lower rate of left atrial appendage obliteration than those without SE events (25.0% vs. 78.6%, P=0.015). Multivariate analysis showed that left atrial appendage obliteration was an independent protective factor for SE in patients undergoing bioprosthetic MVR (P=0.041). ConclusionLeft atrial appendage obliteration is a major protective factor for systemic embolism in patients undergoing bioprosthetic MVR no matter what antithrombotic medication is taken.

MethodsAccording to ADAPTE methodology and status of HAART in China, we searched, appraised, selected and adapted current clinical practice guidelines on the management of medication adherence to HAART. ResultsA total of 10 guidelines were included, and the final clinical practice guidelines for the management of medication adherence to HAART involved 3 aspects, including influential factors, assessment methods, and interventions. High quality evidence resources had been formed, and the quality of final clinical practice guidelines was higher. ConclusionIt is feasible to develop clinical practice guidelines according to the ADAPTE method, and reliable evidence support has been provided for the development of clinical practice guidelines based on guideline adaption.
ObjectiveTo evaluate the diagnostic value of interferon-gamma release assay (TB-IGRA) for tuberculosis in the Tibetan. MethodsFrom January 2014 to December 2014, suspected Tibetan tuberculosis patients were enrolled from AVIC 363 Hospital and underwent TB-IGRA test. All patients were also underwent smear test for Mycobacteria. The diagnostic value of TB-IGRA test for Tibetan TB patients was analyzed. ResultsA total of 77 suspected Tibetan tuberculosis patients were included. According to the diagnostic criteria, of the 77 suspected patients, 50 were diagnosed as TB patients, and 27 were diagnosed as not-TB patients. The sensitivity and specificity of TB-IGRA test was 86% and 81.5%. While the sensitivity and specificity of smear test were 22% and 100%, respectively. ConclusionThe TB-IGRA test is superior to smear test, and is the fast and sensitivity test for diagnosing Tibetan TB patients.
ObjectiveTo translate evidence of "HIV/AIDS Clinical Nursing Practice Guideline" into clinical practice, in order to reduce the incidence and severity of symptoms of AIDS and to improve the quality of life of patients. MethodsWe integrated the best evidence into the HIV/AIDS inpatient unit of a tertiary hospital for infectious disease in Shanghai, China between September 2013 and February 2015. Based on the "Ottawa Model of Research Use", this study was divided into four stages: evaluating the status quo, building the evidence-based strategy, applying evidence-based decision-making, and evaluating results and reflecting. 148 patients were either assigned to an intervention group with HIV/AIDS-related symptom management protocol (n=74), or to a usual care group (n=74) for the duration of their antiretroviral therapy. Then Medical Outcomes Questionnaire (MOS-HIV) were applied to evaluate the life quality after intervention. ResultsMixed-effects regression indicated significant difference between groups across time in total MOS-HIV score. The intervention group increased more than the control group 2.72 points in total MOS-HIV scores per month (P<0.05). ConclusionThe evidence-translation and evidence-based decision-making of "HIV/AIDS Clinical Nursing Practice Guideline" can regulate nurse behavior, raise the quality of clinical care and improve the patients' quality of life.
ObjectiveTo explore feasibility and advantages of hand-assisted laparoscopic radical resection for remnant gastric cancer. MethodsThe clinical data of 26 patients with remnant gastric cancer who underwent hand-assisted laparoscopic (hand-assisted group, n=13) or open (open group, n=13) radical resection from December 2007 to May 2016 in this hospital were retrospectively analyzed. The perioperative outcomes were compared between these two groups. ResultsThere was no conversion to open surgery in the hand-assisted group. Compared with the open group, the incision length was significantly reduced (P=0.000), the intraoperative blood loss was significantly decreased (P=0.038), postoperative the first anal exhaust time was significantly shortened (P=0.025) in the hand-assisted group. The operation time, the number of lymph nodes dissection, and the incidence of postoperative complications had no statistically significant differences between these two groups (P>0.05). ConclusionThe preliminary results of limited cases in this study show that hand-assisted laparoscopic radical resection for remnant gastric cancer is safe and feasible, it has several advantages including small incisions, mild intraoperative hemorrhage, rapid postoperative recovery, better recent clinical therapeutic outcome and so on as compared with open surgery.
ObjectiveTo investigate the changes of amount of interstitial cells of Cajal (ICC) and expression of stem cell factor (SCF)/c-Kit in the process of cathartic colon induced by emodin in mice. MethodsA modified cathartic colon mouse model was established. Seventy-two healthy male Kunming (KM) mice were randomly divided into the blank control group and sustained drug delivery group.Morphological changes of colon in mice were observed; frozen section immunofluorescence was used to observed changes of amount of ICC; serum concentrations of SCF were examined by ELISA; Western blot was employed for observation of expression of SCF/c-Kit in colon. ResultsAfter the mice model were completed, the weight of mouse, length and diameter of entire colon were all reduced compared with the blank control group. The amount of ICC appeared to decline in the beginning of the first 6 weeks with emodin used, and significant decreased in 10-12 weeks. The serum concentrations of SCF first began to decline in 4 weeks with emodin used, and significantly decreased in 6 weeks, and continued at a low level after 8 weeks. The expression of c-Kit in colon began to decline in 4 weeks with emodin used and significantly reduced after 8 weeks. Conciusions The amount of ICC appear to slowly decline in the beginning of the first 12 weeks with emodin used, and significant decrease after 12 weeks.The serum concentrations of SCF and expression of c-Kit in colon have the dynamic changes in the meanwhile, and the changes of SCF are earlier than that of c-Kit. The trend of amount ofICC may have a certain relationship with changes of SCF and c-Kit.
