Clinical research of adenosine triphosphate and spermatic vein ligation combined treatment of children with primary varicocele disease / 中国生化药物杂志

Objective To study the clinical effect of adenosine triphosphate and spermatic vein ligation combined treatment of children with primary varicocele disease.Methods80 cases of children with primary varicocele disease who were treated in pediatric surgery department of Hangzhou City Yuhang District MCH from May 2014 to May 2016 were selected, these children were divided into adenosine triphosphate and spermatic vein ligation combined treatment group (combined treatment group, n= 40) and spermatic vein ligation treatment group (monotherapy group, n=40) two groups according to the random number table, the postoperative pain score, gastrointestinal recovery time, hospital stay, cost of hospitalization, incidence of complications and recurrence of the two groups were statistically analyzed.ResultsThe postoperative pain score and hospitalization cost of the combined treatment group were significantly lower (P<0.05), the gastrointestinal function recovery time and hospital stay were significantly shorter (P<0.05), the incidence of complications 2.5% (1/40) was significantly lower than the monotherapy group 17.5% (7/40) (P<0.05), the recurrence rate 2.5% (1/40) was significantly lower than the monotherapy group 10.0% (4/40) (P< 0.05).ConclusionThe clinical effect of adenosine triphosphate and spermatic vein ligation combined treatment of children with primary varicocele disease is better than spermatic vein ligation treatment alone, so is worthy of promotion in the clinical.

DSSylation, a novel protein modification targets proteins induced by oxidative stress, and facilitates their degradation in cells

Timely removal of oxidatively damaged proteins is critical for cells exposed to oxidative stresses; however, cellular mechanism for clearing oxidized proteins is not clear. Our study reveals a novel type of protein modification that may play a role in targeting oxidized proteins and remove them. In this process, DSS1 (deleted in split hand/split foot 1), an evolutionally conserved small protein, is conjugated to proteins induced by oxidative stresses in vitro and in vivo, implying oxidized proteins are DSS1 clients. A subsequent ubiquitination targeting DSS1-protein adducts has been observed, suggesting the client proteins are degraded through the ubiquitin-proteasome pathway. The DSS1 attachment to its clients is evidenced to be an enzymatic process modulated by an unidentified ATPase. We name this novel protein modification as DSSylation, in which DSS1 plays as a modifier, whose attachment may render target proteins a signature leading to their subsequent ubiquitination, thereby recruits proteasome to degrade them.

The cost-effect iveness analysis of patients with urinary tract infection treated with moxifloxacin and gatifloxacin / 中国医师进修杂志

Objective To estimate the curative effect and cost-effectiveness of moxifloxacin and gatifloxacin for treatment of urinary traet infection. Methods Eighty patients with urinary tract infection were randomly divided into treatment group (40 cases) and control group (40 cases). The patients in treatment group were given 400 mg moxifloxacin once a day for 7 d, while in control group were given 400 mg gatifloxacin once a day for 7d. Results The total clinical effective rate of treatment group and control group were 95.0%(38/40) and 92.5%(37/40) respectively, and the bacterial eliminating rate were 77.50% (31/40) and 76.92% (30/39), and the rate of adverse reaction were 5.0% ( 2/40 ) and 7.5% (3/40) respectively. There was no significant difference between two groups (P>0.05). The cost-effectiveness ratio of moxifloxacin was 2296 and 779 for gatifloxacin (P<0.01). Conclusion The therapeutic scheme of gatifloxacin seems to be the best one for treating urinary tract infection.

STUDIES ON CHARACTERISTICS OF SNAIL DISTRIBUTION IN CANAL AREA INSIDE EMBANKMENT AND FACTORS FORMING HIGH RISK AREA OF SCHISTOSOMIASIS / 中国血吸虫病防治杂志

Zishi township of Jiangling city is located in the canal area inside embankment,a heavy endemic area of schistosomiasis japonica in Hubei province. The population and cattle preva-lence was 29.5% and 66.7% respectively in 1992. There are 66 canals and it covered a total area of 300000m2. 97.0% of the canals and 99.3% of the total area had snail inhabitants, and 7.6% of the snails distributed in canal was infected which covered 18.3% of the total area. The snails were mainly distributed in the main canal and their branches. The rate of snail distribution was 45.2% and 39.8% respectively. Cattle was pastured all year round in this area. Examination of scattered cattle feces and water revealed that the major factor of water contamination was scattered cattle feces. It explained why the infection rate of snail was high and the distribution of infected snail was extensive and how the major high rise area inside embankment was formed.
