BACKGROUND: With the improvement of artificial joint materials, continuous consummation of prothesis design and the maturity of total knee replacement (TKR), excellent effects has been achieved in treatment of serious rheumatoid arthritis (RA) and osteoarthritis with TKR. At present, it is generally thought in China and abroad that staged rehabilitative treatment of step by step should be conducted as early as possible after TKR, which can promote the recovery of patient's knee joint function, and enable patients to freely care themselves so as to enhance their qualities of life.OBJECTIVE: To explain the rehabilitative treatment after TKR and relevant researches.DATA SOURCES: A computer based search of Medline database for relevant articles from January 1998 to August 2005 were conducted with the key words of "total knee replacement, rehabilitation, therapy" and the language was limited to English. Meanwhile, Chinese journal full-text database and Wanfang database were retrieved for relevant Chinese papers from January 1990 to December 2004 with the key words of "total knee replacement, rehabilitation, therapy".STUDY SELECTION: Data were checked in the first trial, accepting criteria:①Items, procedures, process and announcements in the rehabilitative treatment after TKR. ② Retrospective investigations about specific cases. Exclusive criteria: repetitive researches.DATA EXTRACTION: A total of 37 literatures in accordance with above requirements were retrieved and 22 repetitive researches were excluded.Fifteen articles were in accordance with the inclusive criteria: 3 were reviews about TKR and relevant rehabilitative treatment, 8 were clinical researches related to rehabilitative treatment after TKR, 4 were analyzing researches on relevant factors of rehabilitative treatment after TKR. Besides,there were 3 other relevant monographs.DATA SYNTHESIS: Rehabilitative treatment was extremely important to the clinical effects of TKR, which was the key reason why anticipated effects could be achieved after TKR. Exercise for power, training of motion of joint, proprioceptive sensation training and gait training were the most important contents of postoperative rehabilitation treatment. Comprehensive rehabilitative training was essential to maximum recovery of knee joint function including various agonistic muscle training plus extending and flexing power of knee joint; continuous passive training of motion of knee joint in early period plus motion of joint; proprioceptive sensation training in amelioration of motor controllability, postural rectification and balance-keep capability and gait training in correction of abnormal gait.CONCLUSION: Staged rehabilitative treatment of step by step after TKR should be conducted as early as possible, which is absolutely important to exercise for power, training of motion of joint, proprioceptive sensation training, gait training and promotion of functional recovery of knee joints in patients.

OBJECTIVETo summarize laws of acupoint selection of prescriptions for treatment of cervicogenic headache by acupuncture in modern literature.

METHODSRandomized controlled trials (RCTs) involving acupuncture and moxibustion for treatment of cervicogenic headache were recruited from CBM (1978-2012), VIP (1989-2012), Wanfang Database (1998-2012), CNKI (1979-2012), PubMed (1966-2012), EMbase (1980-2012), and Cochrane Library (Volume 4, 2012). Hand recruitment was also auxiliarily used. The frequency and percentage of common acupoints, the distribution of acupoints along 14 meridians and across each part of the body, the application of specific acupoints, and features of using prescriptions for specific acupoints were statistically described.

RESULTSTotally 37 recruited papers included 42 acupoints and 159 times. Common acupoints covered Fengchi (GB20, 28 times), Jingjiaji (EX-B2, 21 times), Baihui (DU 20, 12 times), Tianzhu (BL9, 1 times), and Ashi point (11 times). Meridians along which acupoints were used mainly covered Foot-shaoyang Gallbladder Meridian, Foot-taiyang Bladder Meridian,and DU meridian. Acupoints were mainly needled from head, neck, and upper limbs. Eight confluence points and luo-connecting point were commonest used as specific acupoints. Acupuncture prescriptions were mostly composed of multiple acupoints. Filliform needle was mainly used in acupuncture methods, followed by electro-acupuncture needle.

CONCLUSIONSModern acupuncture treatment of cervicogenic headache focuses on local specific points and acupoints along meridians. Acupoints were mostly selected from head, neck, and upper limbs by syndrome typing of Chinese medicine.

Golgi protein 73(GP73) was closely correlated with primary hepatic carcinoma(PHC). GP73 had a higher sensitivity and specificity than alpha fetal protein(AFP), so GP73 had a great diagnostic value for early PHC. Although there were many related research reports in the domestic and foreign, their conclusions were inconsistent. This article reviewed these studies results.

Objective To explore the levels of serum hepatitis B surface antigen (HBsAg) in different clinical stages of hepatitis B virus(HBV) infection and their correlation with serum HBV DNA. Methods Five hundred and seventy-five patients with HBsAg-positive and without antiviral therapy were enrolled in this study. The patients were classified into six group:IT group (immune tolerant phase, 120 patients), EPH group (hepatitis B e antigen positive hepatitis, 110 patients), LR group (low replicative phase, 90 patients), ENH group (hepatitis B e antigen negative hepatitis, 110 patients), LC group (liver cirrhosis stage, 85 patients) and HCC group (hepatocellular carcinoma, 60 patients). Serum HBsAg and HBV DNA levels were quantified and analyzed through statistics. Results The levels of serum HBsAg in IT group, EPH group, LR group, ENH group, LC group and HCC group were (4.58 ± 0.40), (4.12 ± 0.50), (2.60 ± 0.68), (3.31 ± 0.27), (2.82 ± 0.57) and (3.03 ± 0.39) lg U/ml respectively, and there was significantly different among the different phase (P<0.01). The levels of serum HBsAg in IT group, EPH group, LR group, ENH group, LC group and HCC group had positive correlation with serum HBV DNA level, and the correlation coefficients were 0.627, 0.579, 0.134, 0.317, 0.159 and 0.224 respectively. Conclusions The levels of serum HBsAg is significantly different in the different clinical phase of HBV infection, and the tendency of the correlation between serum HBsAg and serum HBV DNA gradually weakens in general.

Objective To evaluate the psychological intervention ettectiveness ot socioenvironmental therapyfor heroin addicts accepting compulsory isolation.Methods Totally 100 male heroin addicts accepting compulsory isolation and Labour Camp Rehabilitation were selected and randomly assigned to socioenvironmental therapeutic group (ST group,50 cases) and control group (CT group,50 cases).A two-month socioenvironmental therapy was selectively proceeding in ST group by a same psychological team,while CT group still received conventional rehabilitation.During the 6-month follow-up,self-rating anxiety scale(SAS),self-rating depression scal (SDS) and self-made questionnaires were used every 3 months,to statistically estimate psychological status of subjects.Results Before treatment,no statistically significant difference between the two groups;after treatment,SDS score of CT group was 56.16 ± 9.12,and was lower than that in ST group(48.28-± 9.55) (P ＜ 0.01) ; SAS score of ST group was 46.28 ± 7.78,and was lower than that in CT group (50.72 ± 8.32) (P ＜ 0.01).In the 3-month follow-up evaluation,depression,anxiety scores in CT and ST group were significantly lower,the difference was statistically significant (P ＜ 0.01) ; 6 months after treatment,depression,anxiety score showed was significant difference between two groups(P＜ 0.01).Conclusion Group psychotherapy especially socioenvironmental therapy is quick and long-acting in improving the psychological status of heroin addicts in aspects of depression and anxiety levels,which is distinctly evidenced by the short-term and long-term curative results.

The interaction between the antibody and the corresponding target molecule determines the characteristics of immunoassay. In this study, a single chain variable fragment antibody (scFv4C7) derived from the hybridoma strain 4C7 were prepared via genetic engineering technique. The recognition properties of scFv4 C7 was determined and compared to those of the parent monoclonal antibody by indirect competitive enzyme-linked immunosorbent assay(ic-ELISA). Three dimensional structure of the scFv4C7 was presented by Swiss-Model, and sulfathiazole ( STZ) was docked to the scFv4C7 model to obtain the structure of the binding complex. The results from the ic-ELISA showed that the binding properties of scFv4C7 were comparable with the parent monoclonal antibody and STZ was almost completely buried in a deep binding pocket formed by the heavy chain and light chain of the antibody. The interaction between STZ and scFv4C7 was more closely related to the heavy chain and the complementarity-determining region ( CDR ) H3 loop played more important role than other CDR loops. The study preliminary provided the necessary structural information for the preparation of antibody with broader specificity and higher affinity.

Objective To investigate the relationship between the expression level of HOTAIR and cellular radiosensitivity in esophageal squamous cell carcinoma (ESCC). Methods Four ESCC cell lines ( K150, K450, TE-1, and Eca109 ) were used in this study. Quantitative real-time polymerase chain reaction was applied to measure the expression level of HOTAIR in the above cell lines;colony-forming assay was applied to measure the survival fraction of different cells irradiated by different doses of X-ray. The t-test or analysis of variance was applied for analysis of differences. The correlation analysis was used by Pearson methods. Results The four cell lines all showed high expression levels of HOTAIR and radioresistance. Compared with the other three cell lines, Eca109 had a lower expression level of HOTAIR, a lower survival fraction at each radiation dose point, and significantly lower D0 and Dq . The mRNA expression level of HOTAIR and radiosensitivity were K150

OBJECTIVE: To investigate the characteristics and influencing factors leading to sudden cardiac death (SCD) of incarcerated prisoners.
