Objective To analyze the clinicopathologic factors related to the prognosis of gallbladder carcinoma.Methods A retrospective analysis was conducted on 61 cases of advanced gallbladder carcinoma who were operated on from 2001 to 2006 in Nanjing First Hospital.Results According to the 6th UICC/AJCC TNM classification and staging of gallbladder carcinoma,of the 61 patients,8 patients were stage IB,22 were IIA,11 were IIB,14 were III and 6 were IV.Palliative cholecystectomy and/or bile duct drainage procedures were performed in 24 patients;removal of gallbladder plus regional lymph nodes and fatty tissue dissections were performed in 14 cases;radical resection was performed in 7 patients;removal of gallbladder and part of liver in combination with resection of bile duct(radical operatian) was performed in 13 patients;1 patient had extensive radical operation including pancreaticoduodenectomy.In 37 patients,18 had positive lymph node metastasis.Fifty-two patients were followed up,41(67.2%) patients were alive at 6 months after operation,26(42.6%)were alive at 12 months,10(16.4%) were alive at 24 months,and 7 cases were alive at 36 months,1 patient is still alive 5 years after operation;51 patients died within 2 years after operation.The symptoms of recurrence in 31 patients included progressing jaundice(21 cases),metastasis in liver(14 cases),and refractory ascites(12 cases).Five patients died of non-bile duct disease.Conclusions The prognosis of gallbladder cancer has a close relationship with the clinical stage and method of resection.

Objective To investigate the relationship between Atherogenic Index of Plasma(AIP) and the dorsalis pedis artery atherosclerosis in type 2 diabetes. Methods One hundred and twenty-seven patients with type 2 diabetes and 33 healthy individuals were included in the study. The diabetic patients were devided into 2 groups, with( n = 66) or without ( n = 61 ) atherosclerosis. The intima media thickness (IMT) of dorsalis pedis artery were measured by B-mode Doppler ultrasonography. The triglyceride(TG) ,high density lipoproteincholesterol(HDL-C) and other glucolipid metabolic indices were measured in all patients. The AIP was defined as the log value of TG/HDL-C ratio. The one-way ANOVA test was performed to determine the differences among three groups. The relationships between IMT and the other indicators were assessed using Pearson bivariate correlations analysis. The optimal operating point of AIP to diagnose the dorsalis pedis artery atherosclerosis in type 2 diabetes was obtained by drawing ROC curve. Results The AIP value in atherosclerosis diabetic patients,no-atherosclerosis diabetic patients and healthy subjects were 0. 229 ± 0. 132,0. 112 ± 0. 074 and -0. 045 ± 0. 033 respectively. The IMT value were (0. 71 ± 0. 24 ) mm, (0. 49 ± 0. 09 ) mm and (0. 34 ± 0. 15 ) mm respectively. Both indices shown statistical differences among the three groups (Ps = 0. 001 respectively). After adjusting for potential influence factors, AIP showed positive correlation with IMT( r = 0. 315, P = 0. 001 ). The OOP of AIP was 0. 1671 ,the area under the curve was 0. 783. Conclusion AIP was well related to the dorsalis pedis artery atherosclerosis in type 2 diabetes,and the OOP of AIP had good diagnostic reference value in these patients.

Objective The aim of this study was to establish a new method for genotyping ATP7B Arg778Leu gene mutation that does not require RFLP PCR or sequencing.Method 4-primer amplification refractory mutation system (ARMS)-PCR was performed to screen the Arg778Leu mutation in 47 unrelated Wilson's disease (WD) patients and 30 unrelated healthy controls.Direct sequencing was used to confirm the specific amplification products.Results PCR products were visualized on agarose gel electrophoresis.Among the 47 WD patients,4 were homozygous and 14 were heterozygous for this mutation.The total mutation rate was 38.3% (18/47).The results of direct sequencing completely consisted with the results of 4-primer ARMS-PCR.Conclusions The ATP7B Arg778Leu gene mutation is a hot spot for the research of Chinese WD patients.4-primer ARMS-PCR is a fast convenient and accurate method for typing mutation in high throughput population screening.This approach can be used to detect other point mutations.

Objective To analyze and discuss the effect of heat preservation on the recovery time of BIS and the concentration of propofol in the recovery period of the elderly patients with general anesthesia in order to provide guidance for clinical treatment.Methods 78 elderly patients with general anesthesia were selected as the subjects, and the patients were divided into the control group and the study group with 39 cases in each group.The patients were divided into the control group and the study group.Control group, only to be liquid input and covered by drapes, research group take liquid input and peritoneal flushing fluid heating and heating blanket coverage of insulation measures, were recorded and compared between the two groups from anesthesia began to operation to complete the different time points of esophageal temperature and MAP, and to observe the recovery time of patients and effect compartment concentration differences.Results Two groups at T0, T1 esophageal temperature no significant difference, study group T2-T6 esophageal temperatures were significantly higher than those of the control group (P<0.05), maps of the other two groups at different time points had no significant difference;when two groups of patients with propofol withdrawal BIS values had no significant difference, and in the time of discontinuation BIS is more than or equal to 80 recovery time and effect compartment concentration have significant difference (P<0.05).Conclusion The surgical treatment of elderly patients with general anesthesia can help maintain the body temperature, shorten the recovery time of BIS and reduce the concentration of propofol in the recovery period.

Objective To evaluate the effectiveness and safety of fire needle therapy for knee osteoarthritis (KOA), and provide reference for clinic and research. Methods Systematic searches were conducted in PubMed, EMBASE, the Cochrane Library, Web of science, CNKI, VIP, CBM and WanFang Data to collect randomized controlled trials (RCTs) on fire needle therapy treating KOA from inception to August 2013. Two reviewers independently screened articles according to the inclusion and exclusion criteria, extracted data and evaluated the quality of the included studies. Then meta-analysis was performed using RevMan5.2. Results A total of 8 RCTs involving 820 patients were included. According to the different measures of control groups, subgroup analyses was performed and meta-analysis results showed that compared with the routine acupuncture group, the fire needle therapy group in clinical cured rate [OR=2.12, 95% CI (1.48, 3.02), P=0.000 1] and markedly effective rate (OR=3.92, 95%CI (2.65, 5.81), P<0.000 01] aspects all have statistical difference. Compared with the warm acupuncture group, the fire needle therapy group in the markedly effective rate [OR=4.12, 95% CI (1.92, 8.87), P=0.000 3] is statistically significant, but there is no statistical difference between the two groups in clinical cured rate [OR=3.09, 95% CI (0.95, 10.05), P =0.06]. Compared with the acupuncture needle (routine acupuncture and warm acupuncture) group, the fire needle therapy group in the visual analogue scale of knee pain [OR=-0.54, 95%CI (-0.85, -0.24), Z=3.46, P=0.000 5] after treatment is statistically difference. The adverse reactions to fire needle treatment of KOA patients have not been reported. Conclusion Current clinical evidence indicates that fire needle therapy is efficient for relieving clinical symptoms of patients with KOA, and improving their quality of life. However, due to lack of enough high-quality studies, fire needle therapy has to be further studied by conducting more strictly-designed, multicenter and large-scale RCTs.
