ObjectiveTo evaluate the clinical efficacy of intravenous catheter in combination with ultraviolet radiation for postherpetic neuralgia (PHN).Methods96 patients with PHN were randonly divided into three groups.Intravenous catheter plus UVB radiation was given in the test group(32 patients).Intravenous catheter or UVB radiation was only given in two control groups (32 patients/group), respectively.ResultsThe total effective rate in the test group was 96.88％ (31/32) and the average onset time was 1.55 days.However,the total effective rate in two control groups was 81.25％ (26/32) and 68.75％ (22/32) ,and the average onset time was 2.48 days and 7.41days.There was a statistical difference observed in curative rate (x2 = 5.33,42.42, P ＜ 0.05 or P ＜ 0.01), the total effective rate(x2 =4.59,8.89,P＜0.05 or P＜0.01) and the average onset time(t =22.96,11.96,all P＜0.01)between the test group and two control groups.Moreove,there was also a statistical difference observed in curative rate (x2 = 22.44, P ＜ 0.001) and the average onset time (t = 29.30, P ＜ 0.01) between two control groups.ConclusionIntravenous catheter in combination with UVB radiation was much better than intravenous catheter or UVB radiation only in the treatment of PHN.

Mitogen - activated protein kinases (MAPKs), including extracellular signal - regulated kinases (ERKs), c - Jun NH2 - terminal kinases (JNKs) and p38 MAPK, play an important role in transducting environmental stimuli to the transcriptional machinery in the nucleus in mammalian cells by virtue of their ability to phosphorylate and regulate the activity of various transcription factors. It was recently found that the changes in activity of MAPKs occurred during ischemia/reperfusion, but the biological significance of the changes was still controversial.

Objective To evaluate the in vitro antimicrobial activity of tigecycline in combination with imipenem against multi-drug resistant and pan-drug resistant Acinetobacter baumannii isolates,so as to discuss the feasibility of drug combination and provide the basis for chnical rational use of antimicrobial agents.Methods Sixteen multi-drug resistant and pan-drug resistant Acinetobacter baumannii isolates were collected between January and April in 2015 from all kinds of infected specimens of Nanjing Drun Tower Hospital.The protocol was designed by checkerboard method,and the minimum inhibitory concentration (MIC) of antibiotics was determined by microdilution broth method,and the fractional inhibitory concentration (FIC) index was calculated according to MIC results.Results The average value of MIC (MICG),MIC50,MIC90 of tigecycline and imipenem single were 1.73,1,4 μg·mL-1and 31.00,32,64 μg·mL-1.When tigecycline was combined with imipenem,MICG,MIC50,MIC90 of tigecycline and imipenem were 0.24,0.25,0.50 μg·mL-1 and 8.16,8.00,16.00 μg·mL-1,respectively.Compared with the drug single use groups,MIC was significandy decreased in the drug combination group.In 6 strains (37.50％),synergy effect (FIC≤0.5) was observed,and in 10 strains (62.50％),additive effect (0.5 ＜ FIC ≤ 1) was found.No negative and independent effects were shown.Conclusion Both additive and synergistic action is observed when tigecyclineis combined with imipenem against multi-drug resistant and pan-drug resistant Acinetobacter baumannii isolates.No negative and independent effects are shown.This combination use against multi-drug resistant and pan-drug resistant Acinetobacter baumannii may be an effective therapy for clinical treatment.

Objective To study the clinical efficacy of the treatment of traditional Chinese medicine combined with western medicine for extended -spectrum β-lactamase (ESBLs ) bacterial infection associated pneumonia.Methods 80 patients with ESBLs bacterial infection associated pneumonia in our hospital from January 2015 to June 2016 were randomized into the control group (western medicine routine treatment)and the observation group (treatment of traditional Chinese medicine combined with western medicine)according to the random number method,40 patients in each group.The disappearance time of clinical symptoms and signs and hospitalization time, sputum culture results,and the clinical efficacy of treatment in the two groups were compared.Results Compared with the control group,the disappearance time of cough[(6.5 ±1.3)d vs (8.2 ±1.5)d],t=4.38,P<0.05],fever [(5.1 ±1.2)d vs (6.8 ±1.4)d,t=4.19,P<0.05],pulmonary rales[(6.2 ±1.3)d vs (7.8 ±1.6)d,t=4.27,P<0.05]and the hospitalization time[(9.1 ±1.3)d vs (11.8 ±1.6)d,t=5.06,P<0.05]were significantly reduced in the observation group.Compared with the control group,the negative rates of pneumonia klebsiella (25.0% vs 8.0%,χ2 =4.30,P<0.05)and Escherichia coli (70.0%vs 60.0%,χ2 =4.75,P<0.05)in sputum were obviously increased in the observation group.Compared with the control group,the markedly effective rate of treatment was significantly improved in the observation group(92.5%vs 75.0%,χ2 =4.50,P<0.05).Conclusion The treatment of traditional Chinese medicine combined with western medicine can significantly increase the clinical efficacy of ESBLs bacterial infection associated pneumonia,improve the negative rates of sputum bacteria,and it is worthy of clinical promotion.

Objective To discuss the effect of the application of anti-reflux venous indwelling needle after gastrointestinal polyps endoscopic resection.Methods 400 cases of patients after gastrointestinal polyps endoscopic resection were selected in our department.200 cases of patients using ordinary venous indwelling needle were set as the control group.In addition,200 cases of patients chose anti-reflux indwelling needles which were produced by a certain medical instrument Co.,Ltd were set as the experimental group.The incidence rate of phlebitis,tube blocking,blood return and indwelling time in the process of using anti-reflux indwelling needle were observed in two groups.Results During the indwelling time of two kinds of indwelling needles,the incidence rates of phlebitis,tube blocking and blood return of anti-reflux indwelling needle in the experimental group were significantly lower than those of the control group.The average indwelling time of the experimental group was 1.2 days,longer than that of the control group.Conclusions Anti-reflux indwelling needle can effectively protect the blood vessels,ensure the patients to use drugs in time,improve the work efficiency of nurses,reduce the damage to patients and effectively reduce the burden of patients.

Objective To investigate the relationship between hepatitis B virus (HBV) infection and hepatic metastasis from colorectal cancer.Methods Published literatures and unpublished conference papers from January 1990 to December 2011 were searched in PubMed,Cochrane library,Wanfang Database and CNKI.Data of the literatures were extracted by a table.All the patients with colorectal cancer were divided into the infected group and the control group according to the patients whether infected by HBV or not.The hepatic metastatic rate was analyzed.The Meta analysis was carried out by using the Review Manager 5.0 software,and the heterogeneity between studies was analyzed using the I2.Random effect regression model or fixed effects regression model was used according to the P value.The funnel plot was drawn to assess the potential for publication bias.The count data were presented by odds ratio (OR) and 95％ confidence intervals (95％ CI).Results Fifty-six articles were retrieved,and 11 of which met the criteria.The number of patients with colorectal cancer was 5622,and 924 were in the infected group,4698 in the control group.There was no statistical difference in the heterogeneity between all the articles (I2 =0,df=10,P ＞ 0.05).The hepatic metastatic rate was 10.61％ (98/924) in the infected group,which was significantly lower than 23.84％ (1120/4698) of the control group (OR =0.35,P ＜ 0.05).The funnel plot showed that there was no obvious publication bias in these studies.Conclusion Patients with colorectal cancer and infected by HBV have lower incidence of hepatic metastasis.

AIM: To investigate the change and the possible role of mitogen-activated protein kinase(MAPK) subfamilies in early recovery process following acute renal ischemia/reperfusion injury. METHODS: Ischemia/reperfusion renal injury model was made by placing an atraumatic vascular clamp in renal pedicel. The morphologic change was observed by transmission electron microscope. The proliferating cell nuclear antigen(PCNA) positive renal cells were detected by immunohistochemistry. Extracellular signal-regulated kinase (ERK) and c-Jun NH 2-terminal kinase(JNK) activity was assayed by specific substrate phosphorylation with immunoprecipitation. RESULTS: After acute ischemia, microvilli in renal tubular cells appeared again after 2h of reperfusion. At the same time, the PCNA-positive cells were initially increased. ERK activity decreased at 45 min of ischemia, and completely recovered at 5 min of reperfusion. JNK activity was not influenced by ischemia, but increased at 5 min of reperfusion, reaching its maximal activity at 20 min of reperfusion, and prolonged within 2h reperfusion. CONCLUSION: After renal ischemia/reperfusion injury, the early recovery of renal tubule damage was related to the changes of MAPKs in which the increase of JNK activity might be more important.
