AIM:To investigate the protective effects and mechanism of mesenchymal stem cells on renal tubule cells treated by cisplatin.METHODS:The mesenchymal stem cells(MSCs)were separated from mouse bone marrow.The necrosis and apoptosis rate of renal tubule cells induced by cisplatin were detected by flow cytometry.After co-culture with MSCs,the above changes of renal tubule cells were detected.RESULTS:In co-culture system,the apoptotic rates of renal tubule cell were decreased obviously and the cell number increased obviously.CONCLUSION:The MSCs protect the renal tubule cells from apoptosis induced by cisplatin.This effect may be related with the paracrine effects of MSCs.

Late-onset hypogonadism (LOH) is a clinical and bio-chemical syndrome associated with advancing age in males and seriously affects the quality of life of some of the patients. A classical therapeutic option for LOH is testosterone supplementary treatment (TST). Its effectiveness has been verified, whereas its long-term safety remains to be further evaluated. With deeper insights into LOH, many new therapeutic strategies have been proposed, which include the treatments with gonadotropins, testosterone precursors (such as dehydroepiandrosterone [DHEA]), non-aromatizable androgens (such as dihydrotestosterone [DHT]), antiestrogens (such as aromatase inhibitors and estrogen receptor antagonists), and Chinese medicine. Meanwhile, studies on the transplantation of Leydig stem cells, selective androgen receptor modulators (SARMs), and selective estrogen receptor beta (ERbeta) agonists have shed new light on the treatment of LOH.

One hundred and forty-nine patients with moderate and severe organophosphorus poisoning were treated in Fangshan District Hospital, Beijing during July 2005 to July 2007, 77 cases of them with intravenous atropine and intramuscular pyraloxime methylchloride and 72 with intramuscular penehyclidime hydrochloride plus pyraloxime methylchloride. Time of atrepinization, number of medication injection, time of symptom disappearance, recovery time of cholinesterase, length of hospital stay in those with penehyclidime hydrochloride plus pyraloxime methylchloride were all better than those with atropine and pyraloxime methylchloride (P<0.05). Percentage of atropine poisoning, atropine dependence, organophosphorus poisoning rebound and adverse reaction in those with penehyclidime hydrochloride plus pyraloxime methylchloride were lower than those in those with atropine and pyraloxime methylchloride (P< 0.05).

AIM: To observe the influences of Jianwei Yuyang Pills(Radix pseudostellariae,Pericarpium citri reticulatae,Rhizoma dioscoreae, Fructus hordei germinatus,and Fructus crataegi) on the recurrence of peptic ulcer(PU),and the expressions of IL-1 and analyze its potential mechanism. METHODS: Thirty-six patients with gastric ulcer were chosen as Jianwei Yuyang Pills treatment group.In addition,the normal control group was set up(12 cases).The biospy specimens of gastric mucosa was detected to observe the change in immunohischemistry of IL-1 and in the contents of ninohexose and phosphatide of ulcerated gastric mucosa. RESULTS: The contents of ninohexose,phosphatide of PU patients increased in Jianwei Yuyang Pills group.There was a statistical significance between Jianwei Yuyang Pills group(before treatment) and Jianwei Yuyang Pills group(after treatment)(P

Objective To investigate the cavernous nerves innervation from prostate apex to glans penis and the relation between cavernous nerves and surrounding tissues and organs. Methods The urethra and penises of three formalin preserved adult cadavers were removed from prostate apex to glans penis.The sections underwent hematoxylin-eosin staining and Bielschowsky nerve staining.The course and distribution of cavernous nerves and relationship between the cavernous nerves and surrounding tissues and organs was observed microscopically and photographed from prostate apex to glans penis. Results From serial sections we found when nerve fibres run along prostate apex,while surrounding the lateral and dorsal aspects of prostate apex and urethra.from 30'clock to 9 0'clock.Most fibres went through smooth muscle and some of them went through the periphery striated muscle and urogenital diaphragm.The distance to urethra lumen was only 3-5 mm.After the nerve fibres went distally and anteriorly,they accompanied closely with cavernous vein plexus and then went into corpora cavernosa.At the distal end of corpora cavernosa,there were"windows"through which the neurovascular bundles communicated between corpora cavernosa and glans penis just like doors to glans penis. Conclusions When nerve fibres run from prostate apex to urogenital diaphragm,along dorsal lateral aspect of prostate and urethra,there are only 3-5 mm to the urethra lumen,so it is very easy to be injured in traumas or operations.In the urethral bulb fragment,the nerves run anteriorly and laterally.out of the periphary muscle,so the cavernous nerves will not be i~ured when dissect urethra bulb from surrounding muscles.Dissect glans penis from distal end of penis in operation would be avoided in order to protect the cavernous nerves between corpora cavernosa and glans penis.

Objective To investigate the efficacy and safety of full?thickness peroral endoscopic my?otomy( POEM) for achalasia in a follow?up period of 1 year. Methods Data of 28 patients who underwent full?thickness POEM in our hospital from July 2013 to June 2014 were retrospectively studied. Procedure completion and complications were assessed at the end of follow?up of 12 months. Results All patients were treated successfully by full?thickness POEM with the mean operation time of (61?7±15?6) minutes. Intraop?erative mucosal perforation occurred in 2( 7?1%) patients. Symptoms were relieved in 28 patients, but ster?num pain occurred in 6(21?4%) patients. POEM failed in one case in the first 3 months, and was successful in 27 other cases.treatment success rate (Eckardt≤3) was 89?3%(25/28). The incidences of postoperative reflux and esophagitis were 25?9%( 7/27 ) and 22?2%( 6/27 ) , respectively. Conclusion The full?thickness POEM is safe and effective with less complications, but further study is needed to evaluate long?term efficacy and complications.

Objective:To study the cytokine mechanism of Jiawei Xuanfei Toujie Ji(JXT)therapy to influenza infected mouse.Methods:Mice were inoculated intranasally with mouse lung-adapted influenza virus strain(FM1),and were treated with JXT. At 5th days after postinoculation were sacrificed, and IL-2,TNF-?,IL-6,IFN-? in their sera were measured with ELISA kits, their lungs sections were stained with hematoxylin and eosin.Results:Compared with model group ,the levels of IL-2 and IFN-? in JXT group were dramatically higher,and the levels of TNF-? and IL-6 were lower,and pathological effects of influenza pneumonia showed less lung injury.Conclusion:Regulative effects on cytokine may be one of the factors that JXT decrease the pathogenesis of influenza-induced acute lung injury.

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.
