Autosomal dominant polycystic kidney disease (ADPKD) is a most common inherited renal disease, about 50% with a family history, although the exact etiology not yet clear. To date, ADPKD, a multisystem disorder without effective preventive and therapeutic means, has been shown to be detrimental to human health. Recent studies show that severe oligoasthenozoospermia, necrospermia, immotile sperm, azoospermia, epididymal cyst, seminal vesicle cyst, and ejaculatory duct cyst found in male ADPKD patients may lead to male infertility, though the specific mechanisms remain unknown. Structural anomaly of spermatozoa, defect of polycystin, mutation of PKD genes, and micro-deletion of the AZF gene could be the reasons for the higher incidence of abnormal semen quality in male ADPKD patients. Assisted reproductive techniques can increase the chances of pregnancy, whereas the health of the offspring should be taken into consideration. This article presents an overview of reproductive issues concerning infertile male ADPKD patients from the perspective of the morbidity, pathophysiological mechanism, diagnosis, and management of the disease.

Aim To study effects of total flavonoids from stems and leaves of Scutellaria baicalensis Georgi(SSF)on learning and memory deficits, automatic dyskinesia, neural and hepatic pathological changes and free radicals abnormal alterations.Methods Aluminum toxic model of mice was produced by introperitoneal injection (ip) of AlCl_3 for 50 d. Behavioral test of mice was used to examine the learning and memory ability;the number of automatic action determined the automatic dyskinesia;the neural and hepatic pathological changes were assessed by alterations of cerebral cortex and liver;MDA level and SOD activity in brain and liver were measured to evaluate free radicals.Results AlCl_3(100 mg?kg~-1 ,ip,50 d)resulted in a decreased ability of learning and memory in water maze task, lowered automatic action numbers, neuronal-hepatic-pathological changes and free radicals abnormal alterations, as compared with control group. The dose of SSF 50, 100 and 200 mg?kg~-1 significantly reversed the above pathological changes in toxic mice caused by aluminum. Conclusion SSF could reduce cognitive deficits and automatic dyskinesia, improve neuronal-hepatic-pathological changes and free radicals abnormal alterations.

Postweaning multisystemie wasting syndrome (PMWS) is an important swine disease that is closely associated with porcine circovirus type 2 (PCV2). The capsid protein (Cap protein) is a major structural protein that has at least three immunoreactive regions, and it can be a suitable candidate antigen for detecting the specific antibodies of a PCV2 infection. In the present study, an indirect enzyme-linked immunosorbent assay (TcELISA)based on a truncated soluble Cap protein produced in Escherichia coli (E.coli) was established and validated for the diagnostic PCV2 antibodies in swine. The TcELISA was validated by comparison with an indirect immunofluorescence assay (IIFA). The diagnostic sensitivity (DSN), specificity (DSP), and accuracy of the TcELISA were 88.6%, 90.7% and 89.4%, respectively. The agreement rate was 89.38% between results obtained with TcELISA and IIFA on 113 field sera. A cross-reactivity assay showed that the method was PCV2-specific by comparison with other sera of viral disease. Therefore ,the TcELISA will be helpful for the development of a reliable serology diagnostic test for large scale detection of PCV2 antibodies and for the evaluation of vaccine against PCV2 in swine.
5.Developing integrative medicine should pay attention to basic research.
Chinese Journal of Integrated Traditional and Western Medicine 2012;32(6):836-838
After over five decades of vigorous development in China, integrative medicine (IM) has developed into an academic discipline with some overlaps but independent from both Chinese medicine (CM) and Western medicine (WM). CHEN Zhu, the Minister of the Ministry of Health pointed out that IM represents the developing direction for future medicine at the conference commemorating the 50th anniversary of Chairman MAO Zedong' s important instructions on WM doctors learning from CM, which was sponsored by State Administration of Traditional Chinese Medicine and Chinese Association of Integrative Medicine in Beijing on November 27,2008. In this article, the author stresses basic research should be paid attention to in developing IM from the concepts and connotation, development and evolution, achievements and problems, layers and pathways of IM.

Although traditional Chinese medicine (TCM) shows its effectiveness undoubtedly in clinical practice, the deficiency in objective assessment methods is yet a bottleneck which has restricted its development of modernization and internationalization. On the basis of clinical experiences, the authors discussed the title cutting from current situation and tendency, and expanded gradually. It is concluded that by aiming directly at problems and referring to the principle and methods of evidence-based medicine (EBM), using rationally the design in clinical practice and combined with individualization and standardization should be a feasible way for TCM clinical therapeutic effect assessment.

To learn about the economic studies on traditional Chinese medicines in domestic literatures, in order to analyze the current economic assessment of traditional Chinese medicines and explore the existing problems. Efforts were made to search CNKI, VIP, Wanfang database and CBM by computer and include all literatures about economic assessment of traditional Chinese medicines published on professional domestic journals in the systematic assessment and quality evaluation. Finally, 50 articles were included in the study, and the systematic assessment and quality evaluation were made for them in terms of titles, year, authors' identity, expense source, disease type, study perspective, study design type, study target, study target source, time limit, cost calculation, effect indicator, analytical technique and sensitivity analysis. The finally quality score was 0.74, which is very low. The results of the study showed insufficient studies on economics of traditional Chinese medicines, short study duration and simple evaluation methods, which will be solved through unremitting efforts in the future.

OBJECTIVETo evaluate the effect and safety of L-carnitine in the treatment of idiopathic oligoasthenozoospermia based on current clinical evidence.
METHODSWe searched the Cochrane Library, PubMed, MEDLINE, EMBASE, CNKI, VIP, CBM and Wanfang Database from the establishment to April 2014 for the published literature on the treatment of idiopathic oligoasthenozoospermia with L-carnitine. We conducted literature screening, data extraction, and assessment of the methodological quality of the included trials according to the inclusion and exclusion criteria, followed by statistical analysis with the RevMan 5. 2 software.
RESULTSSeven randomized controlled trials involving 751 patients with idiopathic oligoasthenozoospermia met the inclusion criteria, and 678 of them were included in the meta-analysis. L-carnitine treatment achieved a significantly increased rate of spontaneous pregnancy as compared with the control group (RR = 3.2, 95% CI 1.74 to 5.87, P = 0.0002). After 12-16 and 24-26 weeks of medication, total sperm motility (WMD = 5.21, 95% CI 2.78 to 7.64, P < 0.0001 and WMD = 9.29, 95% CI 1.28 to 17.29, P = 0.02) and the percentage of progressively motile sperm (WMD = 12.44, 95% CI 4.58 to 20.31, P = 0.002 and WMD = 9.76, 95% CI 3.56 to 15.97, P = 0.002) were remarkably higher than those in the control group, but no statistically significant differences were observed in sperm concentration between the two groups (WMD = 4.91, 95% CI -2.63 to 12.45, P = 0.2 and WMD = 0.93, 95% CI -3.48 to 5.34, P = 0.68). After 12-16 weeks of treatment, the percentage of morphologically abnormal sperm was markedly decreased in the L-carnitine group as compared with the control (WMD = -2.48, 95% CI -4.35 to -0.61, P = 0.009), but showed no significant difference from the latter group after 24-26 weeks (WMD = -4.38, 95% CI -9.66 to 0.89, P = 0.1). No statistically significant difference was found in the semen volume between the two groups after 12-16 or 24-26 weeks of medication (WMD = -0.13, 95% CI -0.43 to 0.18, P = 0.42 and WMD = 0.28, 95% CI -0.02 to 0.58, P = 0.07). No serious L-carnitine-related adverse events were reported in 4 of the randomniized controlled trials.
CONCLUSIONThe current evidence indicates that L-carnitine can improve spontaneous pregnancy and semen parameters in the treatment of idiopathic oligoasthenozoospermia, with no serious adverse reactions.

OBJECTIVETo evaluate the therapeutic effect of Longjintonglin Capsules on type IIIA prostatitis accompanied by abnormal semen liquefaction.
METHODSWe selected 140 patients with type IIIA prostatitis accompanied by abnormal semen liquefaction according to the diagnostic standards of the American Institutes of Health (NIH) and treated them with Longjintonglin Capsules orally 3 capsules once tid for 12 weeks. We obtained the NIH Chronic Prostatitis Symptom Indexes (NIH-CPSI), traditional Chinese medicine (TCM) syndrome scores, leukocyte count in the expressed prostatic secretion (EPS), semen liquefaction time, and the results of semen analysis and compared these indicators before and after the treatment.
RESULTSOf the 140 cases, 132 were included in this study, excluding 8 due to their incomplete case histories. Before and after 4, 8 and 12 weeks of medication, the total NIH-CPSI scores were 24.52 ± 5.43, 21.28 ± 4.85, 18.01 ± 4.28, and 14.49 ± 3.65 (P < 0.01), the TCM syndrome scores were 35.63 ± 6.07, 26.66 ± 5.03, 17.37 ± 4.18, and 11.11 ± 3.96 (P < 0.01), and the leukocyte counts (/HP) were 27.50 ± 7.01, 22.38 ± 5.22, 16:76 ± 4.10, and 11.40 ± 4.74 (P < 0.01), respectively. After 12 weeks of treatment, 31 of the patients with type IIIA prostatitis were cured and another 72 well responded, with an overall response rate of 78.0%. Of those with abnormal semen liquefaction, 61 were cured, 39 well responded, and 32 failed to respond, with an overall effectiveness rate of 75.8%. Semen analysis showed significantly increased percentage of progressively motile sperm after 4, 8 and 12 weeks of medication as compared with the baseline (P < 0.01). No abnormal liver or renal function or other adverse reactions were observed during the treatment.
CONCLUSIONLongjintonglin Capsules, with its advantages of safety, effectiveness and no obvious adverse effects, deserve to be recommended for the treatment of type IIIA prostatitis accompanied by abnormal semen liquefaction.

The effect of L-proline as a promoter on the condensation reaction of salicylaldehyde or its derivatives with ethyl acetoacetate in neutral ionic liquid [emim]BF4 was studied. All reactions were carried out under mild reaction conditions and achieved high yields. Moreover, the ionic liquid containing L-proline could be recycled and reused for several times without noticeably decreasing in productivity. The results show that the L-proline-[emim]BF4 system has a potential in contribution to the development of environmentally friendly and inexpensive processes in organic syntheses.
