Objective To investigate the preventive effect of the artificial nerve canal on irritating neuralgia after neurilemmoma resection.Methods Thirty patients diagnosed as neurilemmoma were divided into artificial nerve group and control group at randomly.There were 15 patients in each group.The nerves in artificial nerve group were enclosed using the artificial nerve besides neurilemmoma resection.The nerves in control group only had neurilemmoma resection.All patients were assessed with VAS for the degree of irritating neuralgia at 3 time points after operation.Calculate the incidence of irritating neuralgia and analyze the data using statistical methods.Results In control group,the VAS scores were 7.5,5.1,2.8,and the incidences of irritating neuralgia were 80％,67％,40％,respectively.In artificial nerve group,the VAS scores were 3.2,1.5,0,and the incidences of irritating neuralgia were 33％,13％,0.The VAS scores and the incidences of irritating neuralgia of two groups had significant difference by statistical analysis (P ＜ 0.05).Conclusion The artificial nerve canal can relieve the degree and decrease the incidence of irritating neuralgia after neurilemmoma resection,which is a useful method to prevent irritating neuralgia in clinic.

Objective To evaluate the efficacy and safety of telbivudine for pregnant women with hepatitis Be antigen (HBeAg)negative chronic hepatitis B(CHB). Methods Sixty-two cases of HBeAg negative CHB pregnant women were collected from May 2007 to May 2012,and they were divided into telbivudine group (n=31 ,600 mg per day by oral administration)and compound glycyrrhizin group (n=31 ,120 mg per day by intravenous administration).All neonates were given intramuscular injection of 200 IU hepatitis Bimmune globalin at birth immediately and 15 days after birth,and 20 μg genetically engineered hepatitis B vaccine at 0,1 and 6 months after birth.The serum alanine aminotransferase (ALT)level and hepatitis B virus (HBV)DNA titer were monitored.The HBV DNA negative conversion rate,the rate of intrauterine infection,duration of pregnancy,delivery mode,neonate weight and disability rate were compared between groups.All categorical data were analyzed using the chi-square test and comparison between groups was analyzed by t test.Results In telbivudine group,the HBV DNA level before delivery ([0.20±0.11]lg copy/mL)and 6 weeks after delivery ([0.22±0.13]lg copy/mL) were lower than that before treatment [(6.24±0.75 )lg copy/mL]and the differences were statistically significant (t=303.128 and 301 .321 ,respectively;both P <0.01).The negative conversion rate of HBV DNA in telbivudine group was 28 cases before delivery,while in compound glycyrrhizin group,no one had HBV DNA negative conversion.And statistical significant differences were achieved between these two groups before delivery and 6 weeks after delivery (t = -20.285 and -8.721 ,respectively;both P <0.01).In telbivudine group,the ALT levels before delivery and 6 weeks after delivery were (13.08±5.87) U/L and (25.97 ± 17.48)U/L,respectively,which were significantly decreased compared with that before treatment (205.95± 95.69 )U/L.The differences were statistically significant (t = 93.128 and 81.321, respectively;both P <0.01).In compound glycyrrhizin group,the ALT level before delivery ([104.15 ± 69.15]U/L)was lower than that before treatment ([209.60 ± 102.24]U/L)and the difference was statistically significant (t = 9.281 ,P =0.032).However,the ALT level was fluctuant 6 weeks after delivery (150.26± 86.43)U/L,which was not significantly different from that before treatment (t =2.821 ,P =0.122).The ALT levels before delivery and 6 month after delivery were significantly different in both two groups (t=-2.559 and -3.158,respectively;both P <0.05 ).There were no statistically significant differences between these two groups in the rate of intrauterine infection, duration of pregnancy,delivery mode,neonate weight and disability rate.Conclusion The using of telbivudine for pregnant women with HBeAg negative CHB can effectively control the hepatitis activation and reduce the virus titer.

Objective To investigate the effects of acupoint massage on labor analgesia efficacy and it's related clinical factors,so to definite the analgesia mechanism and the relationship between the neurotransmitter dopamine and analgesia mechanism.Methods We choosed patients who have been hospitalized in No.1 hospital from March 2009 to September 2009,and divided them into two groups randomly: observation group and control group.Patients in the observation group were treated with acupuncture massage when the production process went into the active phase.Control group indicated that childbirth was naturally without any treatment.We observed the analgesic effect of point massage and the impact of pressure on the uterine contractions.We tested the dopamine level in the blood by fluorescent spectrophotometry before and afte the acupoint massage.We explored the effects of the point massage on the dopamine level in the puerpera.Results The observation group′s pain decreased more than that of the control group.The intensity of contractions in observation group was decreased more obvious than that of the the control group.The serum dopamine levels was significantly lower than that pre-massage(P

OBJECTIVETo develop a transparent, non-toxic, non-irritating anti-fogging agent with long-lasting effect for nasal endoscopy.

METHODSThe anti-fogging agent was prepared by mixing ethanol, propylene glycol, polyoxyethylene lauryl ether, sodium dodecyl sulfate, polyethylene glycol 400 and deionized water at different proportions based on an orthogonal test design. Twenty-seven test samples of the anti-fogging agents were obtained, which were colorless, transparent, and non-irritating, with a pH value of 7-8. Storz00 nasal endoscopy and its imaging system were used to test the anti-fogging time of the 27 samples, and each agent was tested for 3 times with medical Seoul iodine and 95% ethanol as control.

RESULTSThe optimal composition of the anti-fogging agent was 20% ethanol, 10% propylene glycol, 20% polyoxyethylene lauryl ether, 4% sodium dodecyl sulfate, 4% polyethylene glycol, 42% deionized water. The anti-fogging time of this agent reached 15 min, significantly longer than that of medical Seoul iodine (4 min) and 95% ethanol (18 s).

CONCLUSIONThis anti-fogging agent for nasal endoscopes is colorless and safe and has a long anti-fogging time by forming a homogenous transparent membrane over the endoscopic lens.

To study the genotypes of hepatitis B virus (HBV) in patients from Chongqing district and determine the prevalence of autoantibodies in these patients. HBV genotyping was carried out by restriction fragment length polymorphism analysis of venous blood serum samples from 252 chronic hepatitis B (CHB) patients and 25 healthy controls. Indirect immunofluorescent assay was used to detect autoantibodies, including antinuclear antibody, anti-mitochondrial antibody, anti-smooth muscle (SM) antibody, and anti-liver and kidney microsomal antibody. Immunospot assay was used to detect anti-ribonucleoprotein/anti-SM antibodies, anti-SS-A antibody, anti-SS-B antibody, anti-scl-70 antibody, and anti-Jo-1 antibody. Correlations between the production of autoantibodies and patient age and sex and various genetypes of HBV were analyzed by the Chi-squared test. The most frequent HBV genotype in CHB patients was B (67.3%), followed by genotype C (32.7%). Genotypes A, D, E, F, G and H were not detected in any of the CHB patients. The positive rate of autoantibodies was higher in the CHB patients than in the healthy group (76.98% vs. 12.00%, X2 = 44.60, P less than 0.05). There was no significant differences in the autoantibodies profiles of CHB patients carrying the B or C genotypes ( X2 = 0.0016, P more than 0.05). The main HBV genotypes in CHB patients in the Chongqing district are B and C. Autoantibodies are prevalent among these CHB patients, and are correlated with patient age and course of liver disease but not HBV genotype or patient sex.

Tumor angiogenesis provides adequate oxygen and nutrition for tumor development and supports tumor growth and metastasis. Stromal cell derived factor 1 (SDF-1) and its receptor C-X-C motif chemokine receptor 4 (CXCR4) in pancreatic cancer microenvironment are involved in tumor growth such as promoting tumor cell proliferation, migration, and angiogenesis. In this study, anti-CXCR4 nanobody (CXCR4 Nb) and anti-programmed cell death ligand 1 (PD-L1) &CXCR4 bispecific nanobody (PX4 BsNb) were expressed in Escherichia coli system and purified by nickel column affinity chromatography. We investigated the anti-angiogenesis activity and mechanism of CXCR4 Nb by in vivo and in vitro experiments. Ethical approval was obtained for collection of human peripheral blood mononuclear cell (hPBMC) samples from the Local Ethics Committee of Shanghai Jiao Tong University. All animal experiments were approved by the Animal Ethic Committee of Shanghai Jiao Tong University. The results showed that CXCR4 Nb at 0.1 μmol·L^-1 could effectively inhibit the proliferation and migration of human umbilical vein endothelial cells (HUVEC) promoted by pancreatic stellate cells in vitro. CXCR4 Nb and PX4 BsNb at 0.3 mg·kg^-1 obviously decreased tumor angiogenesis and inhibited the tumor growth in NOD/SCID mice, the inhibitory rates were 28.8% and 36.1%, respectively. CXCR4 Nb significantly inhibited tumor growth and angiogenesis with great safety, which provides support for application of CXCR4 Nb and anti-angiogenesis therapy of pancreatic cancer.
