0.05).The medical expenses of the Hysteroscopic Group was significantly lower than that of the Laparoscopic Group(t=-85.584,P=0.000).Conclusions As compared with laparoscopic conservative operation,hysteroscopic tubal catheterization with MTX injection is another simple,cost-effective,and minimally invasive alternative for early tubal pregnancy.

Objective To compare the different ways of alkaline mouthwash slobber use in preventing the oral infection in patients with fever. Methods The patients who satisfied the requirements were involved and randomly divided into A, B and C group. A group did not use alkaline mouthwash; B group prescribed alkaline mouthwash slobber following the doctor's advice; C group received propaganda and demonstration of intensive use of the alkaline mouthwash, and then used the slobber in right way under the surveillance of nurses. The infection rates of oral ulcer and oral leukoplakia were compared and analyzed among the three groups. Results The incidence rates of oral ulcer and oral leukoplakia gradually decreased among the three groups and the differences had statistical significance (χ2=9.243,P=0.010;χ2=6.495,P=0.033).Compared with A group, there was no significant differences in the rates of oral ulcers and oral leukoplakia between Group A and B(OR=0.486, 95%CI:0.113-2.087;OR=0.557, 95%CI: 0.120-2.583), but the incidence rates of oral ulcers and oral leukoplakia gradually decreased(OR=0.024, 95%CI:0.002-0.293;OR=0.036, 95%CI:0.003-0.448)in C group. Conclusions Strengthening use of alkaline mouthwash slobber is more effective in preventing oral infection in patients with fever compared with the routine way of mouthwash use.

Trigerninal neuralgia is a common refractory disease in clinic. Professor FANG Jianqiao has rich experience through diagnosing and treating the disease for many years. In the first diagnosis, professor FANG underlines the position of damaged neuron and syndrome differentiation. He considers acupuncture should be implemented by stages,namely according to whether the patients are in the period of pain attack, different acupuocture prescriptions are made. Acupuncture manipulation and needle-retention time should be adjusted according to the condition of disease. And the appropriate application of electroacupuncture and transcutaneous electrical acupoint stimulation can strengthen the effect.

OBJECTIVE:To investigate the use of prophylactic use of antibiotics for special diagnosis and treatment in our hos-pital,and to provide reference for rational use of antibiotics. METHODS:The patients receiving special diagnosis and treatment were collected from our hospital during Jan.-Aug. 2016. The prophylactic application of antibiotics was analyzed statistically. RE-SULTS:Among 149 included patients,there were 62 cases of prophylactic use of antibiotics with utilization rate of 41.61％. Among 62 patients receiving antibiotics,5 cases were given medicine orally and others were via injection. Nine categories 18 types of antibiotics were used,involving 69 times;cephalosporin were used in 49 times(71.01％),among which top 3 types in the list of use sequence were cefodizime,cefotetan and cefazolin;prophylactic use of antibiotics was not found in angiography(including coronary artery) and stent implantation. Utilization rate of antibiotics for other diagnosis and treatment was more than 50％. The prophylactic use of antibiotics was complex in ureteroscopy and cystoscopy,shock wave lithotripsy;the selection of drug types started from the high level. There were 59 cases of single drug(95.16％)and 3 cases of two-drug(4.84％). Total of 41 cases were given medicine 0.5-2 h before surgery or at the beginning of anaesthesia (66.13％). Medication time of 18 cases was ≤24 h (29.03％);that of 11 cases was >24-48 h(17.74％). CONCLUSIONS:The prophylactic use of antibiotics is relatively standard in angiography(including coronary artery),stent implantation and implantation of peritoneal dialysis tube in our hospital. There are some problems during special diagnosis and treatment,such as the indication of drug delivery is not strict;the selection of drug types starts from the high level;medication timing is not suitable;medication course is excessively long.

Objective To detect the serum antibody to HPV6 in patients with condylomata acuminata (CA) by use of human papilloma virus(HPV)6bL 1 virus-like particles (VLPS), and to assess the significance of detecting HPV infection. Methods HPV6bL 1 VLPS were produced by a HPV6bL 1 recombinant baculovirus in insect cells,purified by CsCl density gradients centrifugation,and used for ELISA to screen 136 human serum samples in three groups. Results The prevalence of antibody to HPV6bL 1 VLPs was much higher in patients with codylomata acuminata (75%Ab+;mean abs 0.111?0.094) than that in patients with cervical cancer (14.3%Ab+;mean Abs 0.029?0.022)and that in control groups (2.9%Ab+;mean Abs 0.012?0.024). The differences among three groups are significant(P

ObjectiveTo explore the effects of heat treatment and ultraviolet B (UVB) radiation alone or in combination on the expression of heat shock protein (HSP) 72 in human epidermal melanocytes.Methods Melanocytes were obtained from human foreskin,and subjected to primary culture.After 3 to 5 passages,the melanocytes were classified into 4 groups:control group (receiving no treatment),heat treatment group (treated with heat at 42 ℃ for 1 hour every day for 3 days),UVB group(irradiated with UVB at 50 mJ/cm2 daily for 3days),combination group(treated with heat at 42 ℃ for 1 hour followed by irradiation with UVB at 50 mJ/cm2daily for 3 days).After another 2- to 6-hour culture following the last treatment,melanocytes were collected and subjected to real time PCR and Western blot for the detection of HSP72 mRNA and protein expression,respectively.ResultsThe mRNA and protein expressions of HSP72 were significantly higher in the heat treatment group and combination group than in the control group (mRNA:6.584 ± 0.871 and 7.269 ± 0.454 vs.0.975 ± 0.089,both P ＜ 0.001; protein:2.022 ± 0.058 and 2.080 ± 0.045 vs.0.532 ± 0.033,both P ＜ 0.001 ),but was similar between the UVB group and control group (mRNA:0.832 ± 0.084 vs.0.975 ± 0.089,P ＞ 0.05;protein:0.546±0.021 vs.0.532 ± 0.033,P ＞ 0.05).The ANOVA of factorial design showed that neither heat treatment nor UVB irradiation had interaction effect on the mRNA or protein expression of HSP72 (F =2.106,1.399 respectively,both P ＜ 0.05).ConclusionsHeat treatment can cause an increase in the expression of HSP72,which may enhance the function of melanocytes and protect melanocytes from UVB induced damage.

ObjectiveTo investigate the effect of heat treatment combined with narrow band ultraviolet B(NB-UVB) on cultured normal human melanocytes in vitro.MethodsMelanocytes were isolated from the foreskin of normal human,cullured in vitro,and irradiated with NB-UVB of different doses(20,30,50,70,90,120 and 180 mJ/cm2).Then,MTT assay was performed to evaluate the proliferation and activity of melanocytes to determine the optimal dose of UVB for the next experiment.Melanocytes were classified into 3 groups to be treated with heat at 42 ℃ for 1 hour (heat group),irradiated with UVB at 50 mJ/cm2 (UVB group),or irradiated with UVB at 50 mJ/cm2 followed by heat treatment at 42 ℃ for 1 hour (combination group),daily for 3 successive days; those receiving no treatment served as the control.After 24-hour culture following the last treatment,tyrosinase activity was evaluated with L-dopa as the substrate,melanin content was detected by NaOH assay,and cell cycle stages were determined by flow cytometry.ResultsNB-UVB irradiation decreased the viability of melanocytes in a dose-dependent manner,and the optimum dose of UVB was 50 mJ/cm2.The tyrosinase activity of melanocytes was 0.244 ± 0.018 and 0.310 ± 0.015 respectively in the UVB group and combination group,and increased by 3.8％ (P ＜ 0.05) and 31.9％ (P ＜ 0.05) respectively compared with the control group (0.235 ± 0.018); the melanin content was 0.201 ± 0.016 and 0.286 ± 0.019,respectively in the UVB group and combination group,and increased by 17.5％ (P ＜ 0.05 ) and 67.3％ (P ＜ 0.05) compared with the control group (0.171 ± 0.016).In comparison with the control group,the percentage of melanocytes in G1 phase was decreased by 23.94％ in the UVB group(P＜ 0.05) and 33.51％ in the combination group(P ＜ 0.05),while that in S phase and G2 phase increased by 15.35％ (P ＜ 0.05 ) and 11.93％ (P ＜ 0.05),respectively in the UVB group,and 17.76％ (P ＞ 0.05) and 16.08％ (P ＞ 0.05),respectively in the heat group.ConclusionHeat treatment and NB-UVB can synergistically enhance the tyrosinase activity and accelerate melanogenesis,proliferation and differentiation,of melanocytes.

ObjectiveTo observe the increasing effect of infrared irradiation on tyrosinase activity and melanin content in cultured normal human epidermal melanocytes in vitro and to explore the optimal dose of infrared irradiation.MethodsEpidermal melanocytes were isolated from normal human foreskin tissue,and subjected to primary culture.Methyl thiazolyl tetrazolium(MTT) assay was performed to evaluate the effect of different doses(0,20,60,80,100,140,240,320 J/cm2)of infrared light on the proliferation of melanocytes and to select the optimal irradiation dose.Then,melanocytes were irradiated with infrared light at the optimal dose for 3 consecutive days followed by the determination of tyrosinase activity,melanin content,and cell cycle via dopa oxidation assay,NaOH solubilization method and flow cytometry,respectively.ResultsThe best intervention dose of infrared light was 80 J/cm2.The tyrosinase activity(A492 nm) and melanin content(A492 nm)were 0.3601 ± 0.0301 and 0.2748 ± 0.0243 respectively in melanocytes after irradiation with infrared light of 80 J/cm2 for 3 days,significantly higher than those in unirradiated melanocytes(0.3114 ± 0.0341,0.2325 ±0.0254,respectively,both P ＜ 0.05),with an increase rate of 15.64％ and 18.19％ respectively.Cell cycle analysis revealed a decline in cell percentage in G1 phase(P ＜ 0.01 ) but a concomitant increase in cell percentage in G2 and S phase (both P ＜ 0.05) in irradiated melanocytes compared with unirradiated melanocytes.ConclusionsThe optimal dose of infrared light is 80 J/cm2 for the irradiation of melanocytes,and this dose of infrared light can increase melanin content,tyrosinase activity,differentiation and proliferation of melanocytes.

Objective To analyze the status and influencing factors of job satisfaction of nurses at public hospitals, providing references for the teambuilding strategy of nurses. Methods Questionnaire survey method was used, in October 2017, to study job satisfaction of 1,047 nurses at 13 public general hospitals, for a countermeasure study. Results Job satisfaction of the nurses was found at a medium level. Specifically, their overall job satisfaction score was 3. 68, and the satisfaction scores of the following dimensions from high to low were: on-the-job training (3. 91), hierarchical nurse use (3. 79), performance appraisal (3. 68), promotion evaluation (3. 67), and remuneration (3. 62) respectively. Contents of the five dimensions are strongly related to the overall job satisfaction (r＞0. 6). Job satisfaction scores of nurses with their differences in positions, annual income, and hospital level were significantly different (P＜ 0. 05). The three main influencing factors for talent turnover rate are remuneration, workplace pressure and work environment. Conclusions Higher remuneration, improved hierarchical management system, and greater attention to nursing care at secondary hospitals are very important for effectively improving the job satisfaction of nurses and ensuring the health care industry.

OBJECTIVETo evaluate the effects of polymorphisms in XRCC1 and APE1 genes on vinyl chloride (VC)-induced chromosomal damage in peripheral lymphocytes.

METHODSIn this study, 317 workers occupationally exposed to VC were recruited from a factory in Shandong Province, China. The micronucleus (MN) frequency in peripheral lymphocytes was used as an indicator of chromosomal damage. Polymerase chain reaction-restriction fragment length polymorphism and created restriction site combined with restriction fragment length polymorphism were used to determine the five single nucleotide polymorphisms in XRCC1 and APE1 genes in the base excision repair pathway. The association of chromosomal damage with these polymorphisms and the haplotype of XRCC1 was analyzed using Poisson regression and PHASE 2.0.2.

RESULTSIt was found that among the VC-exposed workers, individuals with XRCC1 polymorphisms (-77C/T, Arg194Trp, Arg280His, and Arg399Gln) had a significantly higher MN frequency than those with homozygous wild-type genotypes, with frequency ratios (FR) as follows, respectively: FR = 1.21, 95%CI: 1.05∼1.39 (P < 0.05); FR = 1.14, 95%CI: 1.00∼1.38 (P < 0.05); FR = 1.26, 95%CI: 1.11∼1.44 (P < 0.05); FR = 1.23, 95%CI: 1.08∼1.46 (P < 0.05). APE1 Asp148Glu was found of no significant relationship with MN frequency. Haplotype analysis of XRCC1 demonstrated that the MN frequencies in subjects with CTAA/CTAA and CCAA/CTAA were significantly higher than that in those with TCGG/TCGG (FR = 1.19, 95%CI: 1.02∼1.32, P < 0.05; FR = 1.41, 95%CI: 1.02∼1.87, P < 0.05). Furthermore, association was found between accumulated exposure to VC and XRCC1 polymorphisms (-77C/T, Arg194Trp, Arg280His, and Arg399Gln) after adjustment for age, sex, drinking, and smoking.

CONCLUSIONVC can induce chromosomal damage even when the exposure level is lower than the national occupational health standard of China (PC-TWA: 10 mg/m(3)); the polymorphisms in XRCC1 and APE1 are associated with chromosomal damage induced by VC.
