Objective To evaluate the association of serum uric acid and the incidence and prognosis of kidney diseases systematically, so as to provide reference for the treatment and prevention of kidney diseases. Methods Literatures related to the associations between serum uric acid and incidence and prognosis of kidney diseases were selected from the Chinese Biomedical Literature Database ( CBM) (January 1982 to March 2010), EMBASE (January 1966 to March 2010) and Medline (January 1950 to March 2010) for cohort studies. Two researchers independently screened the studies, assessed the risk of bias of included studies using the Newcastle-Ottawa Quality Assessment Scale for Cohort Studies and extracted data. Stata 10. 0 was used to calculate the pooled relative risk. Results Twenty-one eligible cohort studies were selected, of which 11 on incidence of kidney diseases (n =276 801 ) , and 10 on the prognosis of kidney diseases ( n = 3004). Meta analysis was performed based on data influencing incidence and prognosis factors of kidney diseases except for serum uric acid. The results showed, (1) uric acid and incidence of kidney diseases: hyperuricemia could increase the risk of kidney diseases ( RR = 1. 49, 95% CI 1. 27-1. 75) ; (2) uric acid and prognosis of patients with kidney diseases:hyperuricemia could deteriorate the kidney function (RR = 1. 35, 95%CI 1. 12-1.63) and increase the risk of mortality (RR = 1.67, 95% CI 1.29-2.16). Conclusion Uric acid is an independent risk factor for incidence of kidney diseases and poor prognosis of patients with kidney diseases. Further high quality clinical trials with long-term follow up should be conducted to determine whether lowering uric acid levels would be of clinical benefit in the prevention and treatment of kidney diseases, so as to provide direct evidence for clarifying correlation between uric acid and kidney diseases and the prevention and treatment for patients with high uric acid.

Objective To investigate the effect of soybean isoflavone on histology and uhrastructure of benign prostatic hyperplasia in rats.Methods Male SD rats were injected subcutaneously testosterone propionate for 28 d to induce prostatic hyperplasia,and the rats were divided into 5 groups:control group,model group,and 3 test groups with SI in a dose of 60 mg/(kg·d),120 mg/(kg·d) and 240 mg/(kg·d),respectively.The wet prostate weight,prostatic index,morphological,uhrastmetural and morphometrie changes of the prostatic shndular and interstitial tissues were observed.Results The prostate wet weight,prostatic index and prostatic volumes in all dose groups were significantly lower than those in the models.In comparison with the model group,height of prostatic epithelial cells,glandular average diameters,volumes and surface areas in unit volume,as well as glandular circumferences,glandular relative total volumes and interstitial relative total volumes were all significantly decreased.Glandular counts,density,ratio of glandular surface area to volume,and glandular average curvature were all increased.Conclusions Soybean isoflavone can inhibit prostatic hyperplasia in rats.

Drug testing involves many analytical instruments and test items, sample pretreatment is tedious, the industry's intelligence level remains low, making drug testing a labour-intensive job. However, in the era of Industry 4.0 intelligent manufacturing, intelligent transformation of the quality control (QC) laboratory has become the focus of industry. At the same time, driven by consistency evaluation of the quality and efficacy of generic drugs and the centralized procurement policies, pharmaceutical companies have intensified their competition, further stimulating the intrinsic demand for laboratory intelligence. Based on the current state and future trends of the pharmaceutical industry, this review discusses the development of a digital and automated QC laboratory. It points out the necessity of transitioning from the traditional centralized laboratory model to an intelligent, distributed quality control model to accommodate continuous manufacturing processes. At the same time, it also analyses the potential challenges in the implementation process and coping strategies, in order to provide relevant practitioners with ideas for building intelligent QC laboratories.

Objective To discuss the diagnosis and management of tracheomalacia complicating large goiter. Methods Clinical data of 36 patients with large goiter complicated by tracheomalacia at Xijing Hospital between 1992 and 2004 were retrospectively reviewed. Preoperative Valsalva-Mueller test were performed in all patients before undergoing subtotal thyroidectomy with tracheal suspension, and two patients were treated by subtotal thyroidectomy with tracheal suspension and tracheostomy. Results Valsalva-Mueller test was positive in all patients. The compressed tracheal cartilage disappeared in 2 cases, became thin and soft in other 34 cases. Thirty-four patients who underwent subtotal thyroidectomy with tracheal suspension recovered and 2 patients were resued by tracheal suspension with tracheostomy. There was no mortality. Postoperative 34 cases were followed-up from 6 months to 13 years. Thirty-two cases had no postoperative respiratory obstruction, 2 patients died of unrelated diseases. Conclusions The diagnosis of tracheomalacia from large goiter is based on Valsalva-Mueller test and operative detection. Subtotal thyroidectomy with tracheal suspension is the treatment of choice for tracheomalacia complicating large goiter.

OBJECTIVE To observe the preventive effect on nosocomial infection by the herbal medicine Atractylodes chinensis disinfectant for air sterilization in cardiothoracic surgery.METHODS A.chinensis disinfectant and ultraviolet irradiation were used to disinfect the patients′ rooms of our cardiothoracic surgery department.The total number of germ and fungus in the indoor air before and after using the two methods were collected.The nosocomial infection rates of the same period were also studied.RESULTS A.chinensis disinfectant had strong effect on sterilization of indoor germs and fungi,and the sterilization rate was 92.7%.The comparison between A.chinensis disinfectant and ultraviolet irradiation showed significant difference in their disinfection effects,while no significant difference in their nosocomial infection rates.CONCLUSIONS The herbal medicine A.chinensis disinfectant can achieve good sterilization effect and prevent nosocomial infection.

OBJECTIVETo investigate the effects of glycyrrihizic acid (GA) and prednisone on renal injury in chronic aristolochic acid nephropathy (AAN) rat model.

METHODSNinety-eight male Wistar rats of SPF grade were randomly divided into 4 groups, the normal control group (n = 20), the GA group, the model group, and the prednisone group, 26 rats in each group. Rats in the latter 3 groups were made into AAN model by administration of aristolochic acid (AA, contained in extract of Caulis Aristolochiae Manshuriensis) 20 mg/(kg x d) by gastric gavage, and equal volume of drinking water was given to rats in the control group. Medication was started 2 h later, the GA group was treated with GA 25 mg/(kg x d), the prednisone group with prednisone 3.15 mg/(kg x d), and to the other two groups equal volume of drinking water was given. Body weight was measured weekly, renal function related indices and morphology of the renal tissue were examined at the 4th, 8th and 12th weekend.

RESULTSAlong with the feeding time, body weight in the control group increased steadily, while that in the treated groups increased slowly. The ratio of serum creatinine/body weight increased markedly in the model group, while it significantly lowered in the treated groups. Morphological examination showed that the structural injury in the treated groups was milder than that in the model group, and its degree of fibrosis was milder also (15% - 20% vs 30%). Electronmicroscopy showed that AA induced, injury degeneration and necrosis of renal tubular epithelial cells, and markedly injured the cell organs, such as mitochondria, and induced nuclear variation, while in the treated groups, it was mainly limited in renal tubule, with normal cell organs, few nucleolus variation and less interstitial collagen fibers.

CONCLUSIONGA and prednisone could reduce the serum creatinine level, improve renal function, relieve the renal morphological changes, and decrease the inter stitial fibrosis, showing a definite preventing effect on chronic AAN in rats.
