Objective To investigate the relationship between the severity of diabetic retinopathy and serum bilirubin level. Methods From August 1 2008 to December 31 2009, hospitalized patients of 1062 cases with type 2 diabetes were divided into three groups according to fundus examination: no diabetic retinopathy (NDR) group (457 cases), non-proliferative diabetic retinopathy (NPDR) group (484 cases)and proliferative diabetic retinopathy (PDR) group ( 121 cases). The difference in serum bilirubin level was compared. Results Total bilirubin in PDR, NPDR and NDR group were (9.96 ± 3.84), ( 11.41 ± 3.82),( 13.38 ± 3.98) μ mol/L respectively. There was significant difference among three groups (P < 0.01 ). Logistic multivariate regression analysis showed that a drop in serum total bilirubin level was an independent risk factor of diabetic retinopathy. Conclusions Bilirubin level and the severity of diabetic retinopathy have some relationship. The antioxidant bilirubin and anti-inflammatory effect should be paid attention to.

Objective: To objectively evaluate the short-term and long-term efficacies of arthrolysis under brachial plexus anesthesia in treating adhesive capsulitis of the shoulder (ACS). Methods: One hundred patients diagnosed with ACS were divided into two groups using the random number method. The two groups both received same active rehabilitation exercises. Besides, 55 cases in the treatment group were given one session of arthrolysis under brachial plexus anesthesia, and 45 cases in the control group were given tuina treatment. Changes in the visual analog scale (VAS) score, Melle score and pressure pain index were observed 1 month and 3 months after treatment. The therapeutic efficacies were also compared. Results: The total effective rate was 96.4% at the 1-month follow-up and 96.4% at the 3-month follow-up in the treatment group. The total effective rate was 33.3% at the 1-month follow-up and 28.9% at the 3-month follow-up in the control group. There were significant differences between the two groups comparing the total effective rate at the two time points (both P<0.05). The scores of VAS, Melle and pressure pain were significantly different at the 1-month and 3-month follow-ups from those before treatment in the treatment group (all P<0.05); the three scores did not show significant differences at the 1-month and 3-month follow-ups compared with those before treatment in the control group (all P>0.05). Conclusion: Based on the active rehabilitation exercises, one session of arthrolysis under brachial plexus anesthesia can release the adhesion and restore the range of motion and function of shoulder joint in ACS patients. It is superior to rehabilitation exercises plus tuina treatment comparing both short-term and long-term efficacies.

Heat shock protein 27 ( HSP27 ) is an endogenous protein that plays an important role in a great variety of physio-logical and pathological processes. It can express a large number under body stress conditions. Recent studies have shown estro-gen upregulates the expression of HSP27 through a number of ways, playing a perfect “triple protection” role. In the early stage of atherosclerosis, estrogen induces the phosphorylation of HSP27 via PI3K/Akt signaling pathway. Phosphorylation of HSP27 can resist the injury of vascular endothelial cells( VECs) through an antioxidant and anti-apoptotic pathway as well as the inhibition of cytochrome C. In the stage of forming foam cells, estrogen induces the expression and release of HSP27 from mac-rophages by stimulating the estrogen receptor β ( ERβ) , then HSP27 inhibits the LDL uptake and the release of proinflammato-ry cytokine by binding scavenger receptor A ( SR-A) . During the proliferation and migration of vascular smooth muscle cells ( VSMCs) , estrogen induces estrogen receptor α ( ERα) and protein phosphatase 2 ( PP2A) to form a complex that enhances the activity of PP2A, then it can lead to the dephosphorylation of HSP27 and finally inhibit cells proliferation and migration. In summary, the anti-atherosclerotic effect of estrogen is closely re-lated to the role of HSP27. Given the side effects of estrogen re-placement therapy( MHT) , regulating HSP27 may provide a no-vel therapy for the prevention and treatment of cardiovascular dis-eases in menopausal women clinically.

OBJECTIVE:
To analyze postmortem chemical changes in Landrace costal cartilages and ribs using attenuated total reflection-Fourier transform infrared (ATR-FTIR) spectroscopy, and to provide a novel technique for estimation of postmortem interval (PMI).
METHODS:
The swines were sacrificed by hemorrhage and their costal cartilages and ribs were kept in 20 degrees C. The chemical analysis of the costal cartilages and ribs were performed using ATR-FTIR every 72 h. The correlation between the certain spectral parameters and PMI was also analyzed. The time-dependent changes of costal cartilages were more significant than ribs.
RESULTS:
There were no obvious changes for the main absorbance bands position, and some absorbance band ratios showed time-dependent changes and significant correlations with the PMI.
CONCLUSION
ATR-FTIR has the ability to analyze postmortem chemical changes of the swine costal cartilages and ribs, and it can be a new method to estimate PMI based on spectroscopy.
