Objective To evaluate whether high sensitivity C-reactive protein is associated with microvascular complications in patients with type 2 diabetes mellitus.Methods A total of 321 patients with type 2 diabetes mellitus were recruited.According to the results of 8 h urine albumin excretion rate,ophthalmoscope examination and nerve conduction velocity test,nephropathy,retinopathy and neuropathy were defined respectively.To evaluate differences of the serum hsCRP levels of those with and without nephropathy,retinopathy and neuropathy.Results Only diabetic nephropathy correlated with the serum hsCRP level.With increment of urine albumin excretion rate,hsCRP level was increased.Pearson correlation analysis indicated that hsCRP correlated positively with urine albumin excretion rate(r=0.448,P=0.002),triglyceride(r=0.385,P=0.008),and body mass index(r=0.261,P=0.004).Stepwise linear regression showed that hsCRP and UAER,TG and BMI existed linear correlation.Conclusion hsCRP is associated with diabetic nephropathy and its level is correlated with the degree of diabetic nephropathy.

Literatures on pain intervention with transcutaneous electrical acupoint stimulation (TEAS) were collected by searching the databases both in Chinese and English, and summarized to understand the research progress of TEAS effects on pain mediators in recent years. This will provide a more objective and scientific theoretical basis for clinical practice of TEAS to treat pain syndrome, thus promoting the clinical application of TEAS. Our literature analysis indicated that TEAS effectively regulated the release levels of various pain factors such as prostaglandin, 5-hydroxytryptamine, interleukins, substance P and tumor necrosis factor-α to achieve the analgesic effects by affecting the conduction pathways. TEAS is a safe, non-invasive and effective treatment for pain syndrome. However, further research is necessary due to the lack of rigor of the current clinical trial design.

In order to establish the stable andreliable ISSR-PCR System of Lysimachia christinae, L16 (4(5)) orthogonal design, which based on 7 levels of single factor experiment, were used in this study. The variance analysis was carried out by SPSS 19.0, and 5 main factors affecting the reaction system were optimized in 4 levels. The best annealing temperature was selected by the optimized reaction system. And the stability and reliability of this system was tested by 23 samples from different origins. The results showed that the five factors (DNA template, primer, dNTP, Mg2+ and Taq enzyme) were the most impacts on the amplified results of ISSR-PCR of L. christinae. The order of the influence was: primer > Taq enzyme > DNA template > Mg2+ > dNTP. The optimal system, which was determined by multiple comparison on different levels of each factor, was total volume of 25 microL, including DNA template 60 ng, primer 0.3 micromol x L(-1), dNTP 0.2 mmol x L(-1), Mg2+ 1.8 mmol x L(-1), Taq enzyme 1.25 U. The optimal system was stable and reliable tested by 23 samples from different origins. This study lays the foundation for genetic diversity analysis, fine varieties selection and molecular identification of L. christinae, and provides reference for optimization on ISSR-PCR system of other speciesin future.

In this paper, Fourier transform infrared spectroscopy fingerprint analysis of Marsdenia tenacissima samples was used to develop a reliable method of tracing the geographical origins. Forty-eight samples from four provinces of China were analyzed by FTIR. We analyzed and characterized the fingerprints in both the full spectrum peaks and characteristic peaks, then the principal component analysis and the cluster analysis were carried out. The results of fingerprint analysis, correlation analysis, principal component analysis and cluster analysis can identify the geographic origins correctly, which verified and supplemented each other; the identification results and the actual location showed a high degree of consistency, namely the lower the space distance, the greater the similarity of different samples. These results revealed the obvious superiority and practical value in comparison to the more tedious and time-consuming wet chemistry method normally used. Using appropriate metrology methods can trace the geographical source correctly. The M. tenacissima materials from the region of Maguan should be considered as genuine medicinal materials taking into account the good quality.

An autopsy case of sudden death induced by alimentary tract hemorrhage was presented, which was caused by the unexpected rupture of clinically unrecognized tuberculous abdominal aortic aneurysm (TAAA). The initial diagnosis was made of the syndrome of coronary heart disease and hypertensive disease. The detailed autopsy showed that the alimentary tract hemorrhage was caused by a sudden rupture of the mass after posture changing was ascertained as the cause of death. The diagnosis of TAAA was determined by the autopsy findings. Analysis for the medical dispute of TAAA was described, and the difficulty of the diagnosis and medico-legal implications were also discussed.

OBJECTIVE: To observe the changes of bone element contents in osteoporosis and their interrelationship. METHODS: Twelve female SD rats,10-month-old, were bilaterally ovariectomized (OVX group) and another ten rats were received sham-operation under anesthesia (SHAM group).The element contents in tibia, including Ca, P, Mg, Zn, Mn, Fe, Cu, Mo and Cr, were determined by atomic absorption spectrophotometer 7 month later. The data of contents of all elements were analyzed by simple regression. RESULTS: Compared with the SHAM group rats, the contents of Ca, P and Mg were decreased by 6.6 %(P<0.05), 6.3 %(P<0.05) and 14.9 %(P<0.01) respectively. The contents of Zn and Fe were reduced by 15.2 %(P<0.01) and 35.1 %(P<0.01) separately, Mo and Cr were decreased by 12.2 %(P>0.05) and 14.0 %(P>0.05), while the contents of Mn, Cu and Co were shown no change. There was a significant correlation among the contents of Mg, Mn, Zn, Ca and P. CONCLUSION: The contents of Ca, P, Mg, Zn and Fe were matkedly reduced in bone of osteoporotic rats induced by ovariectomy.

OBJECTIVETo evaluate the effect of ROUX-en-Y anastomosis and Billroth-II anastomosis after subtotal gastrectomy on blood glucose in patients with type 2 diabetes.

METHODSFrom January 2006 to December 2009, 26 and 24 type 2 diabetic patients underwent subtotal gastrectomy for gastric cancer or gastric ulcer and received subsequent ROUX-en-Y anastomosis and Billroth-II anastomosis, respectively. Perioperative and postoperative blood glucose and glycosylated hemoglobin (HbA1c) were detected in these patients to identify the variations.

RESULTSIn ROUX-en-Y group, the fasting blood glucose (FBG) of the patients decreased significantly in the first month after the operation (t=4.46, P<0.05), and the 2-hour postprandial glucose (2hPG) and HbA1c also underwent significant reductions in the first postoperative week and month, respectively (t=3.5, P<0.05; t=2.21, P<0.05). In Billroth-II group, the FBG decreased significantly till 6 months after the operation (t=2.0, P<0.05), and HbA1c reduction occurred 3 months after the operation (t=2.61, P<0.05). There were significant differences in FBG in the first postoperative month, 2hPG in the 6th month, and HbA1c in the 3rd month between the two groups (P<0.05).

CONCLUSIONThe ROUX-en-Y anastomosis and Billroth-II anastomosis after subtotal gastrectomy can both reduce blood glucose of type 2 diabetic patients, but the former approach has better effect.

The proteins encoded by the Brassica juncea chitinase gene BjCHI1 and its derived genes BjCHI2 and BjCHI3 were expressed by Multi-copy Pichia expression system. The chitinase activity of FPLC purified BjCHI1, BjCHI2 and BjCHI3 were tested and the results showed that all the three proteins degraded both CM-chitin-RBV and colloidal chitin. The Km values of BjCHI1, BjCHI2 and BjCHI3 for CM-chitin-RBV were estimated as 0.799 mg/mL, 0.544 mg/mL and 0.793 mg/mL, respectively. When the colloidal chitin was used as substrate, the Km values were 0.281 mg/mL, 0.388 mg/mL and 1.643 mg/mL, respectively, indicating chitin-binding domain can increase affinity of chitinase to insoluble substrate. In the agglutination activity assay, only BjCHI1 shows activity when the protein concentration was more than 33 micrograms/mL, while BjCHI2 and BjCHI3 without agglutination activity even when the concentration was increased as high as 800 micrograms/mL. This means that the two chitin-binding domains in BjCHI1 are essential for agglutination and BjCHI1 is the first protein which shows both chitinase and agglutination activity identified so far in plants.
