Objective To investigate the change of serum transforming growth factor(TGF)-?1 and vascular endothelial growth facter( VEGF) in children with different types of primary nephrotic syndrome( PNS). Methods Children involved in the experiments were divided into simple type group, 16 cases; nephrit was type group, 16 cases, collecting blood sample in prednison - pretreated stage and in prednison- treated stage;control group, 14 cases. Monoclonal EUISA detected TGF-?1 and VEGF. Results Serum level of TGF-?1 and VKGF in active stage of simple type were higher than those of remission stage. The level in nephritis type was no signifi cant difference between prednison- treated stage and prednison - pretreated stage. The level in nephritis type was significantly higher than that in simple type. Conclusion Monitoring the dynamic change of serum TGF-?1 and VEGF can assess the effect of prednison treatment,and evaluate the prognosis of nephrotic syndrome.

A novel sesquiterpenoid (1) and three known compounds identified as isoaltenuene (2), altenuene (3), and alternariol 4, 10-O-dimethyl ether (4), were isolated in our investigation of the cytotoxic constituents from solid cultures of the endophytic fungus Colletotrichum sp. The structures of these compounds were elucidated through spectroscopic data analysis. All compounds exhibited cytotoxic activity against lung cancer cell line A549, breast cancer cell line MDA-MB-231 and pancreatic cancer cell line PANC-1. Compound 4 could induce the PANC-1 cells inflation or death, but couldn't induce apoptosis at the IC50 of 60.2 microg x mL(-1).

OBJECTIVETo investigate the effects of single heat stress treatment on spermatogenic cells in mice.

METHODSWe randomly divided 36 C57 male mice into a control and a heat stress treatment group and submerged the lower part of the torso in water at 25 °C and 43 °C, respectively, both for 15 minutes. At 1, 7, and 14 days after treatment, we obtained the testicular organ indexes, observed the changes in testicular morphology by HE staining, and determined the location and expression levels of the promyelocytic leukemia zinc finger (PLZF) and synaptonemal comlex protein-3 (SCP-3) in the testis tissue by immunohistochemistry and Western blot.

RESULTSThe testicular organ index was significantly lower in the heat stress treatment than in the control group (P < 0.05). Compared with the controls, the heat shock-treated mice showed loosely arranged spermatogenic cells scattered in the seminiferous tubules at 1 day after heat stress treatment, atrophied, loosely arranged and obviously reduced number of spermatogenic cells at 7 days, and relatively closely arranged seminiferous tubules and increased number and layers of spermatogenic cells at 14 days. The number of SCP-3 labelled spermatocytes obviously decreased in the heat stress-treated animals at 1 and 7 days and began to increase at 14 days. The PLZF protein expression was significantly reduced in the heat stress treatment group at 1 day as compared with that in the control (0.19 ± 0.12 vs 0.64 ± 0.03, P < 0.01), but elevated to 0.77 ± 0.02 at 7 and 14 days, even remarkably higher than in the control animals (P < 0.01).

CONCLUSIONHeat stress treatment can induce short-term dyszoospermia in mice, which can be recovered with the prolonged time after treatment.

OBJECTIVE: To investigate the relationship between microalbuminuria and endothelial-dependent relaxing function and atherosclerosis of common carotid artery (CCA) in aged patients with essential hypertension (EH). METHODS: Sixty-four aged EH patients were recruited. According to the albumin excretion rate (AER) in the urine measured by immunoturbidimetry, patients were divided into 2 groups: normoalbuminuria group (NAU group) and microalbuminuria group (MAU group). Thirty aged persons without EH were served as the control group. The endothelium-dependent relaxing function of blood vessels, intima-media thickness (IMT) and the plaque of CCA were measured by color Doppler ultrasound. RESULTS: The flow-mediated dilation in the MAU group [(4.98+/-1.35)%] and that in the NAU group [(6.31+/-1.14)%] were significantly lower than that in the control group [(9.09+/-1.83)%, P<0.05, respectively], especially lower in the MAU group. The IMT of CCA in the MAU group [(0.97+/-0.19)mm] and that in the NAU group [(0.86+/-0.10)mm] were significantly thicker than that in the control group [(0.78+/-0.13)mm] (P<0.05, respectively), especially thicker in the MAU group. The analysis of multiple stepwise regression showed that the microalbuminuria was successively related to EDF, the IMT of CCA, the plaque index of CCA, systolic blood pressure, etc. CONCLUSION EDF is impaired, and there is the atherosclerosis of CCA in aged patients with EH. Microalbuminuria correlates with the decrease of endothelium-dependent relaxing function and the IMT of CCA in aged patients with EH.

Objective: To observe the clinical efficacy of 'Tong Du Yun Pi' (Governor Vessel-unblocking and spleen-promoting) manipulation in treating infantile diarrhea in autumn. Methods: Eighty-four kids were divided into a control group and an observation group using the random number table method, with 42 cases in each group. The control group was intervened by oral administration of montmorillonite powder, and the observation group was given additional 'Tong Du Yun Pi' pediatric massage (tuina) treatment. After treatment, the traditional Chinese medicine (TCM) symptoms scores, symptom improvement time, clinical efficacy and immune function indicators were compared between the two groups. Results: After treatment, the total effective rate was 95.2％ in the observation group versus 76.2％ in the control group, and the between-group difference was statistically significant (P<0.05); each item score in TCM symptoms was notably lower in the observation group than in the control group (all P<0.05); among the effective cases, the times to restore normal defecation, relieve abdominal bloating, arrest vomiting, and bring down the fever were markedly shorter in the observation group than in the control group, and the between-group differences were statistically significant (all P<0.05); the levels of immunoglobulin (Ig) G, IgM, CD4+ and CD4+/CD8+ were significantly higher and CD8+ was significantly lower in the observation group than in the control group (all P<0.05). Conclusion: In the treatment of infantile diarrhea in autumn, based on oral administration of montmorillonite powder, 'Tong Du Yun Pi' manipulation can notably improve diarrheal symptoms, shorten disease duration, and strengthen the immunity of kids, producing more significant efficacy than oral administration of montmorillonite powder.

OBJECTIVETo evaluate the association between serum level of leptin and leptin receptor gene (LEPR) polymorphism and patients with breast cancer.

METHODSLEPR G1n223Arg polymorphism was detected by polymerase chain reaction-restriction fragment length polymorphism in 94 patients with breast cancer and 128 healthy controls. The level of leptin were analyzed by enzyme linked immunosorbent assay.

RESULTSIn univariate regression analyses, we found serum level of leptin and LEPR Gin223Arg genotype polymorphism were significantly higrer than those of the controls (P < 0.05-0.001, respectively). Through multivariable analyses, we found that increased risk estimates for breast cancer were among those with leptin level (OR = 1.53, 95% CI: 1.13-2.07, P = 0.006), LEPR Gin223Arg genotype (OR = 4.87, 95%CI:1.30-18.22, P = 0.019), WHR (OR = 3.68, 95% CI: 1.34-10.11, P = 0.011).

CONCLUSIONResults from this study suggested that LEPR Gln233Agr polymorphism, the elevated WHR and serum level of leptin might be correlated with increased risk of breast cancer.

BACKGROUNDDiagnosis and treatment for respiratory symptoms (RSs) of gastroesophageal reflux disease (GERD) is more difficult than that for common esophageal symptoms. The goal of this study was to evaluate the efficacy and safety of radiofrequency (RF) treatment on RSs of GERD in a preliminary 12-month follow-up observation.

METHODSFrom April 2006 to October 2008, 505 GERD patients with mainly respiratory presentations such as wheezing, chronic cough or hoarseness, were treated by endoscopic RF. A questionnaire was completed before and after treatment, using a six-point scale ranging from 0 to 5 to assess symptom severity and frequency. The symptom score was the sum of frequency and severity.

RESULTSSymptom scores were significantly improved at the end of the follow-up period. The mean heartburn score decreased from 5.31 to 1.79. The mean regurgitation score decreased from 5.02 to 1.64; mean cough score decreased from 6.77 to 2.85; mean wheezing score decreased from 7.83 to 3.07; and mean hoarseness score decreased from 5.13 to 1.81 (P < 0.01). No major complications or deaths occurred. Minor complications included temporary post-procedural retrosternal unease or pain (n = 106; 21.0%), mild fever (n = 86; 17.0%), transient nausea/vomiting (n = 97; 19.2%), and transient dysphagia (n = 42; 9.3%). Thirty-five (6.9%) patients had recurrence of symptoms. Endoscopic RF treatment was repeated in six patients, and laparoscopic fundoplication was performed in seven.

CONCLUSIONEndoscopic RF is an effective and safe means to treat RSs in patients with GERD.
