OBJECTIVETo observe the clinical effect of electric stimulation of long-term retaining needle on analgesia after laparoscopic cholecystectomy (LC) and the impacts on the post-surgical flatus time.

METHODSUnder static absorptive composite general anesthesia, 90 cases of LC were randomized into three groups, 30 cases in each one. In the control group, the analgesia was not applied after LC. In the analgesia-pumper group, the patient controlled intravenous analgesia (PCIA) was used. In the needle-retaining group, the electric acupuncture stimulator was used. The needles were inserted transversely at Riyue (GB 24), Qichong (ST 30) and Yanglingquan (GB 34) and fixed with sterile sticker. Separately, in 8 h and 24 h after surgery, the electric acupuncture stimulation with disperse-dense wave, 2 Hz/100 Hz frequency was applied continuously for 30 min. Visual analogue scale (VAS), adverse reactions such as vomiting and nausea and the postoperative flatus time in 2, 4, 8, 12, 24 and 36 h after surgery were observed and recorded in the three groups.

RESULTSIn 2, 4, 8, 12 and 24 h after surgery, VAS scores in the needle-retaining group and the analgesia-pumper group were all lower than those in the control group (P < 0.05, P < 0.01). The analgesia effect at the above time points in the needle-retaining group was better than that in the analgesia-pumper group (all P < 0.05). There was not adverse reaction in the needle-retaining group. But there were 3 cases of somnolence, 6 cases of nausea and 3 cases of vomiting in the analgesia-pumper group, and 2 cases of nausea and 1 case of vomiting in the control group. The flatus time was quite earlier in the needle-retaining group as compared with the other two groups [(14.77 +/- 4.99) h vs (18.50 +/- 4.22) h, P < 0.01; (14.77 +/- 4.99) h vs (18.17 +/- 4.69) h, P < 0.05].

CONCLUSIONThe electric stimulation of long-term retaining needle is safe and effective in analgesia after LC. It avoids the adverse reactions of analgesics and promotes postoperative flatus.

Objective To explore the investigate of X-chromosome-linked inhibitor of apoptosis pro- tein(XIAP)and its effect on chemotherapeutic sensitivity in bladder carcinoma.Methods Using immu- nohistochemistry methods,the expression of XIAP was evaluated in 47 bladder carcinomas and 6 normal bladder tissues.The XIAP gene was transfected into bladder cancer cell line T24 by liposome and the positive clone was screened by G418.Cellular XIAP mRNA level was detected by RT-PCR.The apoptosis of T24 cells was induced by low-dose of mitocycin C(0.005 mg/ml and 0.05 mg/ml,respectively).The in vitro cellular growth activities were assayed by MTT color imetry;and the apoptosis rate was assayed by TUNEL methods. Results The expression rate of XIAP was 78.7%(37/47)in bladder carcinoma samples,with no corre- lation with carcinoma stages and grades(P＞0.05).XIAP mRNA level in transfected T24 ceils was signifi- cantly increased by 3.8 times.Treated with 0.005 mg/ml and 0.05 mg/ml of mitomycin C,the growth rates of XIAP transfected T24 cells were increased [(11.60?0.25)% and(16.51?0.87)% ,respectively,P＜0.05];and the apoptosis rates were decreased [(10.1?0.2)% and( 11.9?0.2)% ,respectively,P＜0.05]compared with those in control cells.Conclusions XIAP is highly expressed in humun bladder car- cinoma samples.Overexpression of XIAP in T24 cells results in decrease in bladder carcinoma cell apoptosis induced by MMC,which may decrease the chemotherapeutic sensitivity of T24 cells.

OBJECTIVETo investigate the growth status of children under 7 years in Wuzhong City, Ningxia Hui Autonomous Region, China and its influential factors, and to provide a basis for related intervention measures.

METHODSChildren under 7 years were selected from two county-level districts in Wuzhong by stratified cluster sampling, and their growth status were evaluated by the Z score method.

RESULTSThe prevalence rates of growth retardation, underweight, and wasting were 12.58%, 5.71%, and 5.55% respectively. The height-for-age Z score, weight-for-age Z score, and weight-for-height Z scores were -0.26±2.50, 0.29±4.54. and 0.65±3.02 respectively. There were significant differences in the prevalence rate of wasting among children of different ethnic groups (P<0.05); also, there were significant differences in the prevalence rates of growth retardation and underweight among children from different regions and with different age (P<0.05). The main influential factors for growth retardation were region (OR=0.369, P<0.001), ethnic groups (OR=1.694, P=0.027), and age (OR=1.143, P=0.002). The main influential factors for underweight were region (OR=0.453, P=0.001) and age (OR=1.204，P=0.002). The main influential factor for wasting was nation (OR=1.735, P=0.024).

CONCLUSIONSIn Wuzhong, children under 7 years have poor growth status, which are related to ethnic groups, region, and age.

OBJECTIVETo investigate the association of interleukin 6 gene (IL-6) promoter region 634C/G (rs1800796) single nucleotide polymorphism (SNP) with the genetic susceptibility to endometriosis (Ems) in south Han Chinese women.

METHODSA case-control study was performed in 432 Ems patients and 499 control women to evaluate the SNP of IL-6 634C/G by using a fluorescent quantitative PCR-based high resolution melting (HRM) method.

RESULTSThere were statistical significances in the IL-6 634C/G alleles, whether or not to carry allele G and genotype distributions between Ems patients and control women (P=0.032, 0.014 and 0.045, respectively). Allele C enhanced the risk of Ems 1.057 times while allele G reduced the risk of Ems 0.835 time. Carrying allele G reduced the risk of Ems 0.822 time, whereas not carrying allele G enhanced the risk of Ems 1.143 times. Compared with genotype CC, the risk of Ems with genotype CG reduced 0.704 time (95% CI: 0.533-0.931). There was no significant difference in whether or not carrying allele G distribution between Ems patients and control women (P=0.729).

CONCLUSIONThe present study demonstrated significant association between the SNP of IL-6 634C/G and genetic susceptibility to Ems in south Han Chinese women.

Objective To analyze the clinical features, treatment outcomes and prognosis of patients with urinary tract lymphoma. Methods The clinical data of 16 patients in Tongji Hospital of Tongji University from January 2009 to April 2016 were collected and retrospectively analyzed. Results The median age of these patients was 68 years. The onset symptoms of 14 cases were related to urinary system and imaging studies of 10 cases showed masses in the urinary system. The onset regions of lymphoma included:4 cases were renal lymphoma, 5 cases were adrenal lymphoma, 5 cases were testicular lymphoma, 1 case was prostate lymphoma and 1 case was from urethral mouth. The histological type of 12 cases was diffuse large B-cell lymphoma and 10 patients were non-germinal center B cell-like (non-GCB) molecular profiling. Twelve cases belonged to Ann Arbor stages ⅢE- ⅣE, 10 cases had international prognostic index scores ≥3, and 7 cases had B symptoms. 10 patients were confirmed by surgery. Fourteen cases accepted rituximab-containing regimen chemotherapy. Five cases achieved complete response and 3 were partial response. Conclusions The clinical manifestations and imagine examination of patients with urinary tract lymphoma are lack of specificity. The clinical features are highly aggressive and most of the patients are diagnosed at advanced stage. The main histological type is diffuse large B-cell lymphoma and non-GCB molecular profiling. Treatment regimens include surgery combined with chemotherapy and radiotherapy. Earlier diagnosis and treatment may improve the survival of patients.

OBJECTIVETo report the incidence and analyze the factor predisposing to cardiovascular complication after orthotopic liver transplantation (OLTx).

METHODSA retrospective study was made for the patients who develop of all cases in which patients presented with cardiovascular complications after OLTx from April 1993 to December 2001 in the First Affiliated Hospital of Sun Yat-sen University, Guangzhou.

RESULTSEighty-nine liver transplants were performed in 88 patients. Cardiovascular complications developed in 65 (73%) patients. Among these 65 complications, 6 were myocardiac ischemia, 9 were heart failure, 59 were hypertension and 5 were pulmonary hypertension. portoperative mortality rate related to cardiovascular complication was 12.4% (11/89). Except for the preexisting coronary artery disease, the unbalance between coagulant and anticoagulant function in patients after OLTx may play a role in myocardiac ischemia after OLTx. Heart failure was correlated with massive intraoperative blood transplantation (chi2=5.714, P<0.05).

CONCLUSIONCardiovascular complications are common after OLTx. They are severe and highly related to mortality. The unbalance between coagulant and anticoagulant function in patients after OLTx resulting in the thrombosis in coronary artery may be the cause of myocardiac ischemia. Massive intraoperative blood transplantation may be responsible for heart failure.

OBJECTIVETo observe the changes in the hemodynamics of rats with immunological liver fibrosis and explore the pathogenesis of "blood stasis" in liver fibrosis.

METHODSRat models of liver fibrosis were established by multiple intraperitoneal injections of pig serum. The hematocrit, blood viscosity at the shear rate of 150/s, 30/s, 5/s, and 1/s, serum markers for liver fibrosis, and serum transaminase levels were measured in the control and model rats.

RESULTSThe hematocrit, blood viscosity at different shear rates, hyaluronic acid (HA), laminin (LN), procollagen type III (PCIII), type IV collagen (CIV), glutamic-pyruvic transaminase (ALT) and glutamic-oxaloacetic transaminase (AST) increased significantly in the rats with experimental liver fibrosis appeared as compared with those in the control rats. Positive correlations were noted between blood viscosity at different shear rates and serum concentrations of the fibrosis markers (HA, LN, PCIII, and CIV) in the model rats.

CONCLUSIONThe changes in the hemodynamics in rats with immunological liver fibrosis suggests the role of "blood stasis" in the pathogenesis of liver fibrosis and provide experimental evidence for therapies to "activate the blood circulation and dissipate blood stasis" for treatment of liver fibrosis.

OBJECTIVETo investigate the lymph node metastasis and its risk factors in T1-2 staging invasive rectal carcinoma.

METHODSThe data of 1116 patients with rectal cancer treated with total mesorectal excision (TME) technique from January 2000 to April 2009 was analyzed retrospectively. The clinicopathological factors analyzed included gender, age, primary symptom type, number of symptoms, duration of symptom, synchronous polyps, preoperative serum carcino-embryonic antigen level, preoperative serum CA19-9 level, the distance of tumor from the anal verge, tumor size, tumor morphological type, tumor circumferential extent, tumor differentiation and tumor T staging. Statistical analysis was performed by using Logistic regression analysis and Chi-square test.

RESULTSA total of 1116 patients were enrolled, and 358 cases (32.1%) were classified as with T1-2 staging tumor. Two cases (5.6%, 2/36) in patients with a T1 staging tumor were found with lymph node metastasis, and 75 cases (23.3%, 75/322) in patients with a T2 staging tumor, respectively. Compared with patients with T3-4 staging tumor, lymph node metastasis rate of the patients with T1-2 staging tumor was significantly lower [21.5% (77/358) vs. 51.6% (391/758), P < 0.05]. Only the tumor T staging was found as the independent risk factor for the lymph node metastasis in patients with T1-2 staging tumor on multivariate Logistic regression analysis (odds ratio: 5.162; 95%CI: 1.212 to 21.991; P = 0.026).

CONCLUSIONSA substantial proportion of T1-2 staging rectal cancers harbor metastatic lymph nodes and the clinicopathological features except for T staging fail to predict the lymph node metastasis. Further research is warranted to identify the risk factors and guide the clinical practice in patient with T1-2 staging tumor.
