Conslusions Compared with the traditional operation,PPH has the advantages of simpleness,less pain,less complications and quiker recovery,but the cost is higher.

An accurate location of acupoint is one of the key factors for improving clinical therapeutic effect of acupuncture and moxibustion. From the theoretical basis, operation method, principle discussion and clinical application, the clinical practicability of the two-step location method of acupoint in Internal Canon of Medicine is discussed. This two-step location method is in accord with the original connotation of acupoint, and focuses on the function state of acupoint. As is suggested in clinical researches, the acupoint location that is acquired by using the two-step location method, as a treated area, could obviously improve the therapeutic effect of acupuncture and moxibustion. Therefore, the two-step location method of acupoint in Internal Canon of Medicine should be considered as guideline of clinical acupoint location.

Two patients underwent liver transplantation of blood type incompatibility were collected from Fuzhou General Hospital of Nanjing Military Area Command of Chinese PLA. Case 1: A male who had primary hepatic carcinoma underwent classic orthotopic liver transplantation; the blood of donor was type A, and the blood of recipient was type O. Case 2: A female having history of type B hepatitis underwent classic orthotopic liver transplantation due to pregnancy combining with severe liver disease and coagulation disorder; the blood of donor was type B, and the blood of recipient was type O. Immunohistochemistry staining was used to observe pathological changes and deposition of various immunoglobulin and complement in two cases following liver transplantation of blood type incompatibility under optic microscope and to investigate diagnostic standard of humoral rejection. The results showed that linear or granular depositions of IgG, IgM, IgA, C4c, C4d, and Clq were found in endothelial cells of hepatic sinusoid, suggesting that IgG and other immunoglobulin exhibited a strongly positively diffused deposition on the endothelial cells of hepatic sinusoid, while expression of C4d and other complements was also found. All those mentioned above could be considered as evidences to prove onset of humoral rejection in transplanted liver tissue.

Objective To investigate the aetiology of acute exacerbations of COPD (AECOPD),and the effects of moxifloxacin in the treatment of AECOPD.Methods Patients with stable COPD based on GOLD criteria were included in the study.Sputum collected at first exacerbation was analyzed for bacteria count and culture.IL-6,IL-8 and TNF-?were measured by enzyme- linked immunosorbent assay (ELISA).Eligible patients were randomized to receive moxifloxacin (400 mg qd for 5 days) or ce- faclor (250 mg q8h for 7 days).Efficacy parameters were evaluated at 7 and 14 days after treatment initiation and 1 year later. Results Of the 46 patients with moderate or severe COPD (male 38,moderate 24),21 (45.65%) were microbiologically evalu- able at baseline.The main pathogen was Haemophilus influenzae (10/21).Clinical efficacy rate was 87.0% in moxifloxacin group and 82.6% in cefaclor group.Bacterial eradication rate was 80.0% and 72.7% respectively.The difference between groups was not statistically significant in terms of clinical or microbiological efficacy.In moxifloxacin arm,the frequency of ex- acerbation was 2.6?1.0,significantly lower than control arm (3.5?1.4,P

Objective To investigate the optimal scheme about the external loading of resetting tensile stress for clavicular fracture,so as to provide some mechanical references for optimal design of external fixators for clavicular fracture.Methods The shoulder CT scanning data from a volunteer were used to establish the three-dimensional model of human left shoulder by Mimics software.In order to better simulate the actual human shoulder,the ligament tissues were added in the model and the constraints of muscles were considered,and the experimental model for simulation analysis on resetting tensile stress was established.By 3 simulation experiments,the impacts from directions of resetting tensile stress,positions of action points and value ranges were simulated and analyzed,respectively.The resetting tensile stresses obtained from clavicle of the shoulder model under various external loading cases were simulated by orthogonal test methods.Results When the θ (angle between the horizontal plane projection of shoulder force which was loaded by external fixator and the coronal axis) was greater than 45°,clavicle could obtain the resetting tensile stress,which became greater with the angle θ increasing.When η (angle between the sagittal plane projection of shoulder force which was loaded by external fixator and the sagittal axis) was 30°-45°,the resetting tensile stress of clavicle was the maximum.The farther the position on which the loads from external fixator was exerted from the horizontal position of clavicle,the larger the resetting tensile stress of clavicle was.Conclusions The results of orthogonal test show that the optimal resetting tensile stress is produced with parameter combination of θ =65°,η =50°,acting on the center of humerus head of the shoulder.

This study examined the promoter methylation of APO-1/CD95 (Fas) gene in bladder urothelial carcinoma and analyzed the relationship between the Fas promoter methylation and the biological behavior of bladder cancer. Promoter methylation of Fas gene was detected by methylation-specific PCR (MSP) in 4 bladder cancer cell lines, 50 human bladder urothelial carcinoma samples and l0 normal bladder tissue samples. Correlation of the aberrant methylation of Fas promoter with the clinicopathological parameters was statistically analyzed. The results showed that Fas was down-regulated at both mRNA and protein level in bladder cancer cell lines and tissue samples of bladder urothelial carcinoma. The positive rate of Fas protein expression in bladder urothelial carcinoma was 34.0% (17/50), significantly lower than that in normal bladder tissues (70.0%, 7/10) (P<0.01). Fas promoter methylation was detected, and the positive rate of Fas promoter methylation in bladder urothelial carcinoma was 42.0% (21/50), which was obviously higher than that in normal bladder tissues (0.0%, 0/10) (P<0.01). The aberrant methylation of Fas promoter was reversely correlated with Fas protein expression (P<0.05). Furthermore, the positive rates of Fas promoter methylation in high-grade and low-grade bladder urothelial carcinoma were 73.3% (11/15) and 34.2% (12/35), respectively, with significant difference shown (P<0.05). No statistical significance was found in the Fas promoter methylation among different clinical stages of bladder cancer. It was concluded that Fas promoter hypermethylation plays an important role in the pathogenesis of bladder urothelial carcinoma and may serve as a prognostic indicator of bladder urothelial carcinoma.

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 Cryptococcosis is a potential life-threatening systemic mycosis with a heterogeneous susceptible popu-lation which is classified into three groups according to the current guidelines, including AIDS patients, organ transplantation recipients ( OTR) , and non-HIV-infected and non-transplant hosts ( NHNT) .This study aimed to discuss the influence of basic diseases on the clinical features and prognosis of NHNT cryptococcosis patients. Methods Using a retrospective cohort study design, we retrieved the clinical data about 73 NHNT cryptococcosis patients treated in Jinling Hospital.Based on the presence or absence of immunodefi-ciency or infection-increasing complications, we divided the patients into a basic disease group ( n=35) and a non-basic disease group ( n=38) and analyzed their clinical characteristics, chest radiographic features, laboratory results, and clinical outcomes. Results Compared with the non-basic disease group, the basic disease group showed a significantly higher incidence rate of disseminated disea-ses (62.9%vs 21.1%, P<0.01), more cases of patchy consolidation (47.4%vs 16.7%, P<0.05) and mixed lesion (31.6%vs 3.3%, P<0.05) in chest radiography, and a higher mortality (30.0%vs 5.3%, P=0.016). Conclusion Basic diseases have a great impact on the clinical features and prognosis of NHNT cryptococcosis.NHNT patients with basic diseases are susceptible to dis-seminated diseases with severer clinical symptoms and a higher mortality.

Objective To investigate the effects of ropivacaine infiltration combined with dezocine on the agitation during recovery from general anesthesia in the patients undergoing cerebral surgery.Methods Sixty patients of both sexes,aged 18-64 yr,of ASA physical status Ⅰ or Ⅱ,undergoing elective neurosurgery under general anesthesia,were randomly divided into 4 groups (n =15 each) using a random number table:control group (group C),ropivacaine group (group R),dezocine group (group D),and ropivacaine + dezocine group (group RD).Group C received local infiltration with normal saline 20 ml at 10 min before skin incision,and normal saline 2 ml was injected intravenously at 30 min before the end of operation.The patients received local infiltration with 0.5％ ropivacaine 20 ml at 10 min before skin incision,and normal saline 2 ml was injected intravenously at 30 min before the end of operation in group R.Group D received local infiltration with normal saline 20 ml at 10 min before skin incision,and dezocine 10 mg was injected intravenously at 30 min before the end of operation.The patients received local infiltration with 0.5％ ropivacaine 20 ml at 10 min before skin incision,and dezocine 10 mg was injected intravenously at 30 min before the end of operation in group RD.The time for recovery from anesthesia,extubation time,and development of agitation after extubation in PACU were recorded.Agitation was assessed and scored.Ramsay sedation score and VAS score were recorded immediately after extubation.The development of cardiovascular events and respiratory depression was recorded within 10 min after extubation.Before induction of anesthesia (T0),at the end of surgery (T1) and immediately after extubation (T2),blood samples were collected from the dorsal artery of foot for deter mination of the levels of blood glucose,plasma cortisone,epinephrine and norepinephrine.Results Compared with group C,the agitation score,incidence of agitation,VAS score,and incidence of postoperative hypertension were significantly decreased in R,D and RD groups,especially in R and D groups.The time for recovery from anesthesia and time for extubation were significantly shorter in R and RD groups than in group C.Ramsay sedation scores were significantly higher at the onset of extubation in R,D and RD groups than in group C.Ramsay sedation scores were significantly higher in D and RD groups than in group R.Compared with group C,the levels of blood glucose,plasma cortisone,epinephrine and norepinephrine were significantly decreased in R,D and RD groups,especially in group RD.Conclusion Ropivacaine infiltration combined with dezocine can reduce the agitation during recovery from general anesthesia in the patients undergoing cerebral surgery.
