Objective To investigate the serum concentrations of connective tissue growth factor (CTGF) and serum cystatin C(CysC) in diabetic nephropathy(DN) patients and its clinical significance. Methods 82 cases of diabetic nephropathy patients were divided into three groups by urinary albumin excretion rate(UAER):normal al-buminuric group(group 1),microalbuminuric group(group 2),macroalbuminuric group(group 3). Serum concentra-tions of CTGF and CysC were determined by ELISA, which was compared with 20 cases of control group. Results CTGF and CysC were markedly higher in the three groups than that in healthy controls [CTGF: (87.65±6.09)、 (105.36±7.78)、(129.05±5.12) ng/L and (68.29±5.90) ng/L;CysC: (0.99±0.10)、(1.59±0.14)、 (2.53±0.27) mg/L and (0.82±0.56) mg/L, P<0.05]. CTGF, CysC were all positively correlated with UAER (r=0.80、0.21, P<0.05), all negatively correlated with glomerular filtration rate (eGFR) (r=-0.85、-0.88, P<0.01). Conclusions The serum concentrations of CTGF and CysC may be early markers in predicting diabetic nephropathy and assessing its severity.

Distress thermometer (DT) is a widely used rating scale for testing distress severity in cancer patients in recent years.Recent studies have indeed showed that DT is worth being used in oncology clinic because of its acceptable validation.More and more studies have demonstrated the important role of DT on exploring distress.It may provide important basis for improving the distress in cancer patients.

[Objective] To introduce a modified method for immunoblotting in detecting protein and to show all the details needing to be paid attention to. We take COX-2 for example. [Method] Total proteins were extracted and quantified. Denatured proteins were separated by SDS-PAGE and were transferred semi-dryly to NC membrane, then the latter was bound with specific antibody. Finally, protein expression was detected by ECL.[Result] The method was concise and easy to manipulate. The method had been successfully used to detect COX-2 protein in our lab and the pictures were reproducible. [Conclusion] Every step of the method is described in detail. It is helpful for novice to carry out immunoblotting. This established method is worthy to be recommended.

Objective To study the effect of follicle stimulating hormone(FSH)on the secretion of anti-mullerian hormone(AMH)in granulosa cells in patients with polycystic ovarian syndrome(PCOS).Methods From Aug.2008 to Dec.2009,33 patients with PCOS in Reproductive Medicine Research Center,Sixth Affiliated Hospital of Sun Yat-sen University were collected from 8-10 mm antral follicles and classified into the following three groups: FSH-unstimulated granulosa cells(unstimulated group,n =12),exogenous FSH-stimulated granulosa cells(exo-stimulated group,n =12)and internal FSH-stimulated granulosa cells(int-stimulated group,n =21).ELISA and real-time PCR were relatively used to measure protein and mRNA level of AMH.Luciferase reporting vector was constructed to detect the promoter activity of AMH.Results The levels of AMH secretion in PCOS granulosa cells were(11.4 ± 4.0)μg/L in unstimulated group,(7.9 ± 1.1)μg/L in exo-stimulated group and(5.6 ± 1.7)μg/L in int-stimulated group.Both the external and internal stimulation of FSH may suppress AMH secretion significantly(P ＜0.05).The mRNA level of AMH in PCOS granulosa cells were 2.5 ± 1.2 in unstimulated group,which were higher than 1.5 ± 0.5 in exo-stimulated group and 1.1 ± 0.7 in int-stimulated group significantly(P ＜0.05).The luciferase activity of AMH in PCOS granulosa cells were 11.5 ± 2.3 in unstimulated group,8.7 ± 2.4 in exo-stimulated group and 6.8 ± 2.4 in int-stimulated group.The luciferase activity of AMH in unstimulated group was significantly higher than those in exo-stimulated and int-stimulated groups(P ＜0.05).Conclusion FSH may inhibit the excessive secretion of AMH and stimulate follicle growth in PCOS granulosa cells by suppressing activity and expression of promoter.

Objective To investigate the concentration changes and clinical significance of hepatocyte growth factor (HGF) during the development of acute kidney injury (AKI). Methods The serum concentrations of HGF in 62 patients with AKI were measured every two days, and the relation between HGF and glomerular filtration rate (eGFR) ,the renal failure index,course of diseases,numbers of viscera injury,and short-term prognosis were an-alyzed. Results The serum concentrations of HGF were progressively rising along with the course of diseases and the amount of viscera injury (P=0.000), reached peak at the 9th day, and then decreased, which was was elevated in the death group than renal function failure group, but which in the latter group was elevated than in renal function recovery group (P<0.05 for each). AKI with liver injury patients were obviously higher than without liver injury pa-tients(P<0.05 for each). The serum concentrations of HGF were positively correlated with the renal failure index (r=0.580～0.821) but negatively correlated with eGFR(r=-0.943～-0.703) (P<0.05 for each). Conclu-sion The serum concentrations of HGF are abnormally rising in the patients of AKI ,which reflects the state of dis-ease and short-term prognosis of AKI.

Objective To compare the effectiveness of the forced-air warming system and the conventional warming care practice in preventing hypothermia in patients undergoing major surgeries.Methods A total of 62 patients were enrolled in this study. Patients of both sexes,aged≥18 years,and with an ASA physical status Ⅰ-Ⅲ were included and allocated randomly into intervention group(n=30)or control group(n=32). Patients in the intervention group were provided forced-air warming,either prior to induction or during the surgery procedure depending on core temperature monitoring results. In the control group,patients were warmed with conventional warming care without any intervention. Core temperature was measured by Spot-On sensor and tympanic membrane thermometer,blood pressure,the electrocardiogram,heart rate,pulse oxygen staturation,and partial pressure of end-tidal COwere also monitored continuously in the two groups.Crystalloid,colloid,and allogeneic blood were also recorded by strict protocol. Results Intraoperative hypothermia monitored with tympanic thermometer was observed in 23 patients(71.87%)in the control group,which was significantly higher than that (0) in the intervention group(P=0.00). In addition,the incidence of hypothermia monitored by Spot-On sensor was 81.25%(n=26)in control group and 13.33%(n=4)in intervention group(P=0.00). Conclusion Compared with the conventional warming care,forced-air warming system is more effective in preventing hypothermia during major surgeries.

OBJECTIVE:To provide reference for small interfering ribonucleic acid (SiRNA) R&D and registration in China. METHODS:The situation of SiRNA R&D at home and abroad were introduced,and problems encountered in the evaluation and approval process were summed up to put forward suggestions. RESULTS & CONCLUSIONS:SiRNA has developed slowly in Chi-na,with a gap of 5-10 years at least compared with foreign developed countries. The registration category of SiRNA is not clear;applicants lack of guidance documents;production workshop which meet requirement is in shortage;the efficiency of drug registra-tion allows of no optimism. It is recommended that pharmaceutical registration departments carry out the pilot reform for SiRNA registration,publish SiRNA registration guide,relax regulations for IND gradually,encourage applicants to participate in the inter-national multicenter clinical trials in order to improve the efficiency of SiRNA evaluation and approval efficiency.

Under the current national conditions, qualified person are repositioned, and after learning the advanced experience of the EU, the registration system is strictly carried out, which can promote the professionalism of qualified person and make relevant measures in order to restrict the behavior of qualified person.

Acromegaly is mostly caused by a pituitary adenoma secreting growth hormone ( GH ) , which leads to a wide range of endocrine morbidities, with an insidious onset and slow progression.A long-term overproduction of GH results in elevated insulin-like growth factor-1 ( IGF-1 ) level, which in turn, would cause target organ damage and an increased risk for mortality and decreased quality of life.Herein, the literature regarding the progress of drug therapy for acromegaly in recent five years is reviewed.

Objective To observe the curative effect of acupuncture on insulin receptor substrate 1 ( IRS-1) , IRS-2 and glucose transporter 4 (GLUT4) in skeletal muscle of experimental rats with insulin resistance (IR) . Methods Thirty-two rats were randomly divided into normal group, model group, acupuncture normal group and acupuncture model group. The fasting plasma glucose ( FPG) level was detected with glucose oxidase method, fasting insulin and C-peptide ( C-P) were examined with enzyme linked immunosorbent assay ( ELISA) , insulin sensitivity index ( ISI) was calculated, and IRS-1 mRNA, IRS-2 mRNA and GLUT4 mRNA of skeletal muscle were observed by real-time PCR-based fluorescent assay in each group. Results Compared to the normal group, the FPG, FINS, C-P levels were increased dramatically (P<0.01), ISI, IRS-1 mRNA, IRS-2 mRNA and GLUT4 mRNA of the model group declined remarkably ( P<0.01). Compared to the model group, the FPG, FINS, C-P levels declined evidently ( P<0.05 or P<0.01) , and ISI, IRS-1 mRNA, IRS-2 mRNA and GLUT4 mRNA of the acupuncture model group were increased dramatically ( P<0.01). Conclusion The curative mechanism of acupuncture for insulin resistance is probably related to the increase of IRS-1 mRNA, IRS-2 mRNA and GLUT4 mRNA expression in skeletal muscle which contributes to the improvement of PI3K signal pathway.
