Objective To assess the safety and efficacy of the local nerve block anesthesia procedure in daysurgery inguinal herniorrhaphy practice.Methods Fifty-eight inguinal herniorrhaphy were performed under the local nerve block anesthesia in the form of day surgery between April 2014 and April 2015 other 58 inguinal hemiorrhaphy were performed under general anesthesia.Time of operation,hospitalization stay,complications and costs were evaluated.Results The average operating time of the day-surgery group was (47 ± 12) min.All operations were completed successfully.Fifty-six patients were discharged in 24 hours and 2 patients were discharged in 48 hours after the surgery.The average costs were 8437 yuan.The rate of postoperative complications was approximately 6.6％ (4/58),including hematoma(3 cases),urinary relention(1 case),and chronic pain (1 case).The VAS scores of 6 hours after the operation were (2.4 ± 0.8).Conclusions It suggests that preperitoneal hemiorrhaphy under the local nerve block anesthesia in the form of day-surgery was safe and effective.Also,it could significantly shorten the time of hospitalization and reduce medical costs.

Objective To determine the significance of MDR -1 and MRP mRNA expression in periph-eral blood lymphocytes in lung cancer patients with chemotherapy treatment .Methods Peripheral blood samples were taken from each lung cancer patient before chemotherapy and three weeks after the first chemotherapy cycle . The expressions of MDR-1 and MRP were tested for 39 lung cancer cases using RT -PCR technique comparing to 20 normal control cases .Results There was no significant difference for MDR -1 mRNA and MRP mRNA ex-isting in lung cancer cases and control group (P>0.05).MDR-1 and MRP mRNA expressions were increased after treatment of chemotherapy courses in almost all pathological types of lung cancer .Furthermore,the expres-sion level in small cell lung cancer after chemotherapy was significantly higher than that before .Conclusion Chemotherapy may induce the incidence rate of MDR -1mRNA and MRP mRNA expression in lung cancer .Ade-nocarcinoma and squamous cell carcinoma are mainly intrinsic MDR while small cell lung cancer is mainly ac -quired MDR to chemotherapy .Based on the positive expression rate of MDR -1 mRNA and MRP mRNA in pe-ripheral blood ,we may evaluate the results of chemotherapy in lung cancer patients easily and conveniently .

Objective To evaluate the feasibility and efficacy of ultrasound-guided popliteal vein catheter thrombolysis for acute deep venous thrombosis of the lower extremity.Methods Clinical data were retrospectively analyzed on 120 patients of unilateral acute lower extremity deep vein thrombosis from April 2010 to April 2013.60 cases were included in systemic thrombolytic group; 60 cases into catheter directed thrombolysis group.Thrombolysis rate and limb swelling reduction rate were calculated and compared between the two groups.Results Due to limb swelling rate,in systemic thrombolysis group:Thigh swelling reduction rate was (77 ± 9) ％ ; Leg swelling reduction rate was (70 ± 11) ％,while in catheter directed thrombolys group,that was (87 ± 5) ％,and (80 ± 9) ％,respectively (P ＜ 0.05).The thrombolysis rate in systemic group was (59 ± 14)％,that was (71 ± 13)％ in catheter directed thrombolysis group (P ＜ 0.05).Conclusions Ultrasound guided precutaneous catheter popliteal vein thrombolysis significantly improves the short-term outcome of deep venous thrombosis in terms of leg swelling reduction rate and thrombolysis reduction rate.

Objective To analyze the differential gene expression between thymic carcinoids and normal thymic tissues and to study thepathogenesisofectopicACTH syndrome caused by thymic carcinoids. Methods Using gene chip technique, the gene differential expression of 2 tissues were observed following RNA labeled with different fluorescences (Cy3 and Cy5) hybridized to gene chip. Results Among 4224 genes on gene chip, 394 were up regulated more than 2 folds in thymic carcinoid tissues, 23 of which were associated with cell mitosis; 51 genes were upregulated more than 5 folds, 1 of which (PAK3) was associated with cell mitosis. Conclusion A group of differentially expressed genes were observed between the thymic carcinoids and normal thymic tissues.These overexpressed and cell mitosis-associated genes probably play a role in the pathogenesis of thymic carcinoid tumors.

Objective:To evaluate Castor single-branch covered-stent in the treatment of Stanford B aortic dissection(TBAD)with insufficient anchorage zone.Methods:Clinical data of 25 TBAD patients (proximal healthy landing zone ≤15 mm) treated with Castor branched stent-graft at Weifang People's Hospital from Apr 2019 to Sep 2021 were analyzed retrospectively.The stent model was selected according to preoperative CTA examination and intraoperative angiography,the operation result and follow up data were reviewed.Results:The operation success rate was 100%,the mean operative time was (137.8±35.8)min, and the mean blood loss was (52.8±24.5)ml. There were 2 cases of internal leakage (IA) and it was disappeared after balloon dilation, Branched stent stenosis occurred in 2 cases and relieved by balloon dilatation. The mean follow-up time was 14.6 months, and the patency rate of branch stent was 100% during the follow-up period. The true lumen diameter of thoracic aorta was significantly expanded and the false lumen diameter was significantly reduced 3 months after surgery compared with that before surgery ( P<0.05). Conclusion:Castor stenting in the treatment of TBAD with insufficient proximal anchoring area is simple and feasible, with satisfactory short term clinical effect.

Objective:To study the genotype distribution of drug-related gene polymorphism of methotrexate (MTX) and leflunomide (LEF) in patients with rheumatoid arthritis (RA).Methods:The genotyping results of RA patients' MTX and LEF related genes(MTHFR677C/T, MTHFR1298A/C, ABCB13435T/C, DHODH19C/A and CYP1A2734C/A) detected in Shanghai Guanghua Hospital from December 2018 to May2019 and drug-related adverse effect were statisticallyanalyzed. The independence of allele distribution was tested by Hardy-Weinberg test. Counting data of genotypes and allele frequencies among the groups were analyzed by the chi-square test. Measurement data were showed as Mean±SD deviation. The network between incidence of adverse events and genotypes of patients was analyzed by cytoscape software. Results:Genotype distribution in 151 patients was consistent with Hardy-Weinberg genetic balance ( P>0.05), and genotype and allele distribution of each gene showed no statistical difference in gender ( P>0.05). The results showed that the most common genotype in RA were that genotypes of the good response with moderate resistance to MTX (MTHFR677CC/MTHFR1298AA/ABCB13435CT) (16 cases, 13.5%) and the good response with moderate side effect risk to LEF(DHODH19CC/CYP1A2734AC) (25 cases, 28.4%). According to the distribution frequency of alleles, the incidence of high side effects caused by MTX combined with LEF was predicted to be 2.9%, which was close to 1.8% of the actual genotypes of patients. The types and proportion of clinical adverse reactions in patients were retrospectively analyzed and the correlation network analysis was conducted with the genotype analysis results. It was found that the incidence rates of adverse reactions were liver injury (35.4%, 35/99), leukopenia (14.1%, 14/99), thrombocytopenia (2.0%, 2/99), and skin rash (1.0%, 1/99) from the top to the bottom. The top two genotypes that were related to the occurence of adverse events were MTHFR677CT/MTHFR1298AA/ABCB13435CT and DHODH19CA/CYP1A2734AC, respectively, which verified the consistency between drug-related genotype and clinical manifestations in RA patients. Conclusion:Our results suggested that genotype in RA patients is closely related to drug efficacy and adverse events. 2.9% of RA patients need to stop taking MTX and LEF due to high MTX resistance and poor MTX response and increased toxicity when combined with LEF, in which the proportion of liver injury is the highest.

ObjectiveTo investigate the use of contraceptive methods， and to evaluate maternal healthcare services utilization among women within 2 years in Pudong New Area of Shanghai. MethodsA cross-sectional survey was conducted using a questionnaire for women at different postpartum periods who visited a community health clinic with their children from June to November 2021. Data were analyzed using χ² test and binary logistic regression. ResultsAmong the 1 946 postpartum women surveyed， 1 934 were either married or cohabiting， and1 430 had resumed their sexual life. Among women at 4， 6， 12， 18 and 24 months postpartum， the contraceptive prevalence rates （CPR） were 92.34% （193/209）， 92.16% （235/255）， 87.31% （282/323）， 91.95% （297/323） and 90.00% （288/320）， respectively. The modern contraceptive prevalence rates （mCPR） were 87.08% （182/209）， 87.06% （222/255）， 82.04% （265/323）， 83.09% （271/323） and 85.31% （273/320）， respectively， while the unmet contraceptive needs （UMNs） were 7.66% （16/209）， 7.84% （20/255）， 11.46% （37/323）， 6.81% （22/323） and 10.00% （32/320）， respectively. The use rates of long-acting reversible contraceptive （LARC） methods among women at 6， 12， 18 and 24 months postpartum period were 0.39% （1/255）， 2.17% （7/323）， 0.31% （1/323）， and 2.81% （9/320）， respectively. Among all surveyed subjects， 32.17% （626/1 946） had received postpartum contraceptive services only once， while 27.85% （542/1 946） had not received any postpartum contraceptive services. Binary logistic regression analysis indicated that the use of contraceptive methods among postpartum women was associated with whether relevant educational services were received after childbirth and during postpartum home visits （all P<0.05）. ConclusionPostpartum women have unmet needs for contraception. Contraceptive guidance at the 42-day postnatal healthcare visit needs to be further strengthened and postpartum contraceptive education could be integrated into the pregnancy care. The quality and effectiveness of contraceptive education during delivery and postpartum home visits， and even at the 42-day postnatal healthcare visit need to be further explored.
