Objectives To analyze the risk factors of uterine rupture in pregnancy in Chengdu Women’s and Children’s Central Hospital in recent years. Methods The clinical data of pregnant uterine rupture patients who were hospitalized in Chengdu Women’s and Children’s Central Hospital from January 2011 to December 2017 were collected. The risk factors of uterine rupture in pregnancy were analyzed compared with the maternal delivery during the same period. The SPSS 23.0 software was used for statistical analysis. Results A total of 69 patients with uterine rupture were included, involving 14 cases of complete uterine rupture and 55 cases of incomplete uterine rupture. Compared with the pregnant females who were hospitalized during the same period, the incidence of uterine rupture in patients with scar uterus after cesarean section, history of laparoscopic hysterosalping surgery, placental implantation, twins and uterine malformation was higher, and the difference was statistically significant (P<0.05). Among them, the risk of uterine rupture was greater in the interpregnancy interval (IPI)>24 months after cesarean section in patients with scar uterus. There was no significant difference in the incidence of uterine rupture between the elderly and the multiple pregnant females and the maternal delivery during the same period (P>0.05). Conclusions Scar uterus (postoperative cesarean section), history of laparoscopic hysterosalping surgery, placental implantation, twins, and uterine malformation are possible risk factors for uterine rupture in pregnancy. Among them, patients with scar uterus have a greater risk of uterine rupture with IPI>24 months.
Objective To analyze and compare the domestic quality standard and foreign quality standard of sodium hyaluronate (HA), and to expatiate on the critical process monitoring parameters. Methods Different quality standards of HA were compared by translating and sorting, and some experimental data were analyzed as well as the manufacturing practice was elaborated. Results Differences exist in raw materials standard or specifications of products between domestic and foreign, but the basic control points are concordant. Conclusion The company should set up reasonable and controllable quality standard based on quality requirements and related process characteristics so as to assure the safety and effectiveness of the clinical application.
Objective To review the eradication rate for Helicobacter Pylori (H. pylori) eradication therapy with Ranitidine bismuth citrate (RBC). Methods A systematic review of all the relevant randomized controlled trials (RCTs) was performed according to International Cochrane Collaboration. Data Source RCTs were identified from specialized trials register of Cochrane U GDP Group, the Cochrane library, additional electronic search (including MEDLINE and CBM), handsearching, and personal contact with pharmaceutical companies. Data Selection Randomized clinical trials comparing RBC or RBC in combination with other antibiotics such as proton pump inhibitor, H2-receptor antagonist, other bismuth or placebo were included. No language and blinding limitations were applied. Inclusion criteria Data were extracted independently by two reviewers. The methodological quality of trials was assessed by the Jadad-scale plus allocation concealment. Statistics analysis was managed by using RevMan 4. 1. Results Fifteen randomized clinical trials including 3 638 patients were included, with eight trials of high methodological quality. Meta-analysis indicated that odds ratio was 3.06 (95%CI 2.62 to 3. 58, P lt; 0. 000 01) comparing RBC to controls. But the heterogeneity was significant (P lt; 0. 000 01), so we choose random effects model. Then the odds ratio was 2.05 (95%CI 1. 29 to 3. 25, P=0.002). No serious adverse effects were found. Sensitivity analysis showed that the specimens and the quality of RCT haven’t affected researching result. Conclusion RBC is more effective in Helicobacter Pylori eradication therapy than others.

Methods From January 2007 to December 2008, 120 neck lymph nodes of 102 patients confirmed by pathology were divided into two groups, including 68 metastatic lymph nodes and 52 lymphoma lymph nodes. The reports of two groups were performed using two-dimensional ultrasonography and power Doppler imaging (PDI). The long-short axis ratio (L/S), structure, blood flow pattern of lymph nodes were studied. Results The rate of the lymph door disappearance, inner liquefacient position and central blood stream in two groups had statistical difference (Plt;0.05). The rate of irregular form, diminution of cortical resonance, blood stream of lymph door and peripheral flow in two groups had statistical difference (Plt;0.05), but the difference of their L/S≤2 had no statistical significance (Pgt;0.05). Conclusion The ultrasonography is a valuable method for diagnosing between neck metastatic nodes and lymphoma lymph nodes.
Objective To investigate the association between polymorphism of S2 locus allele in ADAM33 gene and bronchial asthma in Xinjiang Uygur population.Methods PCR-RFLP was used to determine polymorphismof S2 locus allele in ADAM33 gene in 131 Uygur patients with bronchial asthma ( asthma group) and 90 Uygur healthy individuals ( control group) .Results The comparison of three genotypes and allele frequency of the S2 in the ADAM33 gene had statistical significance in the asthma group and the control group ( X2 =6. 065, P lt;0. 05;X2=5. 255, P lt;0. 025) . The G allele of S2 site increased the risk of asthma( OR =1. 616, P lt;0. 05) . The CG genotype also increased the risk of asthma ( OR= 1. 351,P lt;0. 05) . The FEV1% pred and FVC% pred had significant difference between three genotypes of the S2 site in the ADAM33 gene in the asthma group ( F = 6. 248, P lt; 0. 01; F = 7. 067, P lt; 0. 01) .Conclusion The polymorphism of the S2 site in the ADAM33 gene has significant correlation with asthma in Xinjiang Uygur population, and can increase risk of asthma in the Uygur population.
Liposomes with precisely controlled composition are usually used as membrane model systems to investigate the fundamental interactions of membrane components under well-defined conditions. Hydration method is the most common method for liposome formation which is found to be influenced by composition of the medium. In this paper, the effects of small alcohol (ethanol) on the hydration of lipid molecules and the formation of liposomes were investigated, as well as its coexistence with sodium chloride. It was found that ethanol showed the opposite effect to that of sodium chloride on the hydration of lipid molecules and the formation of liposomes. The presence of ethanol promoted the formation of liposomes within a certain range of ethanol content, but that of sodium chloride suppressed the liposome formation. By investigating the fluorescence intensity and continuity of the swelled membranes as a function of contents of ethanol and sodium chloride, it was found that sodium chloride and ethanol showed the additive effect on the hydration of lipid molecules when they coexisted in the medium. The results may provide some reference for the efficient preparation of liposomes.
Objective To assess the effect of nonsteroidal anti-inflammatory drugs (NSAIDs) for the prevention of colorectal neoplasia. Methods A systematic review of all relevant randomized controlled trials and quasi-randomized controlled trials of NSAIDs for prevention of colorectal neoplasms was performed by using The Cochrane Collaboration recommended methods. Results Nine trials were included and assessed. There was sufficient evidence for aspirin to prevent the development of colorectal adenomas compared with placebo in three trials of high quality and large sample size with relative risk (RR) 0.81, 95% confidence interval (CI) 0.72 to 0.91 and P=0.000 5 . No adequate evidence supported aspirin in the prevention of development of colorectal cancer (RR 0.97, 95% CI 0.79 to 1.20, P= 0.79). However, there was no evidence to support sulindac and celecoxib curing or preventing colorectal adenomas or familial adenomatous polyposis (RR 0.71, 95% CI 0.49 to 1.03, P= 0.07 and RR 0.90, 95% CI 0.76 to 1.07, P=0.23). No evidence on the dose of NSAIDs was used for prevention of colorectal adenomas at present. No significant difference was seen in the number of adverse events between patients taking NSAIDs and those taking placebo (P=0.9). Conclusions Aspirin may prevent the development of colorectal adenomas and may avoid polypectomy for 1 in every 10 to 18 persons but we don’t know whether aspirin can be substituted for endoscopically removed colorectal polyps. However, the true clinical benefit for prevention of colorectal neoplasia of NSAIDs should be considered.
Objective To investigate the effect of anti-seizure medications (ASMs) pregabalin (PGB) monotherapy on sleep structure and quality of patients with focal epilepsy. MethodsAdult patients whom newly diagnosed focal epilepsy were collected and treated with PGB monotherapy. The main outcome measures were the changes of polysomnography and video-electroencephalography (PSG-VEEG), Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI) and Epworth Sleepiness Scale (ESS) in epilepsy patients with PGB and baseline. Results PGB improved significantly sleep structural parameters, including increased total sleep time (P<0.001), decreased sleep latency (P<0.001), improved sleep efficiency (P<0.001), reduced wake time after sleep onset (P<0.001), increased sleep maintenance efficiency (P<0.001) and proportion of N3 sleep stage (P<0.001). In the group with poor sleep efficiency, 86.7% of patients achieved sleep efficiency>85% after PGB treatment. The difference was statistically significant (P<0.01). PGB reduced significantly PSQI score (P<0.001) and ISI score (P<0.001). No significant change in ESS score was observed (P>0.05). ConclusionsPGB could enhance slow-wave sleep (SWS), increase sleep quality and improve insomnia in patients with epilepsy without causing daytime sleepiness.
ObjectiveTo investigate the clinical effect of transversus abdominis plane (TAP) block as part of multimodal analgesia in enhanced recovery after surgery (ERAS) program for patients with hepatic hydatidosis. MethodsThis study was a randomized controlled trial (The registration number was ChiCTR2100053689). According to the established inclusion and exclusion criteria, the patients diagnosed with hepatic hydatidosis treated in the People’s Hospital of Aba Tibetan and Qiang Autonomous Prefecture from October 2019 to August 2021 were prospectively included. The odd and even by obverse and reverse of coin was adopted to assign into the study group and the control group, respectively. The patients in the study group were treated with ERAS + TAP block + patient controlled intravenous analgesia (PCIA) + tramadol and the patients in the control group were treated with ERAS + PCIA + tramadol. The intraoperative and postoperative statuses of the two groups were compared. ResultsA total of 64 patients were enrolled in this study, including 32 patients in the study group and 32 patients in the control group. There were no statistical differences in the baseline data such as the age, gender, preoperative complications, preoperative liver function, and liver hydatid type between the two groups (P>0.05). The operations of 64 patients were performed successfully, and there was no perioperative death. There were no statistical differences in the operation time, intraoperative bleeding, and operation mode between the two groups (P>0.05). Compared with the control group, the points of visual analogue scale of postoperative pain on day 1 and 2 were lower (P<0.05), the dosage of tramadol within 2 d after operation and hospitalization expenses were less (P<0.05), and the getting out of bed time, eating liquid diet time, postoperative exhaust time, and total hospital stay were shorter (P<0.05) in the study group. The total complication rate of the study group was lower than that of the control group [28.1% (9/32) vs. 78.1% (25/32), χ2=16.063, P<0.001]. The comprehensive complication index was positively correlated with the total hospital stay (r=0.941, P<0.001) and hospitalization expenses (r=0.958, P<0.001). ConclusionPreliminary results of this study suggest that multimodal analgesia included TAP block is effective in ERAS, and could shorten hospital stay and reduce hospitalization expenses.
Objective To evaluate effectiveness of proximal femur bionic nail (PFBN) in treatment of intertrochanteric fractures in the elderly compared to the proximal femoral nail antirotation (PFNA). Methods A retrospective analysis was made on 48 geriatric patients with intertrochanteric fractures, who met the selection criteria and were admitted between January 2020 and December 2022. Among them, 24 cases were treated with PFBN fixation after fracture reduction (PFBN group), and 24 cases were treated with PFNA fixation (PFNA group). There was no significant difference in baseline data such as age, gender, cause of injury, side and type of fracture, time from injury to operation, and preoperative mobility score, American Society of Anesthesiologists (ASA) score, Alzheimer’s disease degree scoring, self-care ability score, osteoporosis degree (T value), and combined medical diseases between the two groups (P>0.05). The operation time, intraoperative blood loss, number of blood transfusions, transfusion volume, length of hospital stay, occurrence of complications, weight-bearing time after operation, and postoperative visual analogue scale (VAS) score, walking ability score, mobility score, self-care ability score were recorded and compared between the two groups. And the radiographic assessment of fracture reduction quality and postoperative stability, and fracture healing time were recorded. ResultsThe operations in both groups were successfully completed. All patients were followed up 6-15 months with an average time of 9.8 months in PFBN group and 9.6 months in PFNA group. The operation time was significantly longer in PFBN group than in PFNA group (P<0.05), but there was no significant difference in intraoperative blood loss, number of blood transfusions, transfusion volume, length of hospital stay, change in activity ability score, and change in self-care ability score between the two groups (P>0.05). The weight-bearing time after operation was significantly shorter in PFBN group than in PFNA group (P<0.05), and the postoperative VAS score and walking ability score were significantly better in PFBN group than in PFNA group (P<0.05). Radiographic assessment showed no significant difference in fracture reduction scores and postoperative stability scores between the two groups (P>0.05). All fractures healed and there was no significant difference in fracture healing time between the two groups (P>0.05). The incidence of complications was significantly lower in PFBN group (16.7%, 4/24) than in PFNA group (45.8%, 11/24) (P<0.05). ConclusionCompared with PFNA, PFBN in the treatment of elderly intertrochanteric fractures can effectively relieve postoperative pain, shorten bed time, reduce the risk of complications, and facilitate the recovery of patients’ hip joint function and walking ability.
