Serum concentrations of total and ester cholesterol and Lp-X of 82 hepatobi-liary diseases were determined. It shewed that the levels cf total cholesterol and LP-X in cholestasis due to extrahepatic obstruction are significantly higher than that in intrahepatic cholestasis. Both levels exceeded 200 mg/dl in 12 out of 18 cases of extrahepatic obstruction caused by carcinoma, but they never exceeded 200 mg/dl in 41 cases of intrahepatic cholestasis.Quantitation of both Lp-X and total cholesterol in cholestasis appears to provide more informafions than the determination of other one of them alone. Determination of free or ester cholesterol gives little clinical value in distin-quishing extrahepatic from intrahepatic cholestasis.

Objective To investigate the clinical characteristics of islet auto-antibodies and ?-cell function in patients with ketosis-prone diabetes(KPD). Methods A total of 78 patients with KPD were divided into four categorical groups based on the presence or absence of auto-antibodies (A+ or A-) and of ?-cell functional reserve(?+ ?-):A+?+(group 1,n=13),A-?-(group 2,n=18),A-?+(group 3,n=28),A+?-(group 4,n=19).Islet auto-antibodies,including glutamic acid decarboxylase antibody(GAD-Ab),islet cell antibody(ICA)and insulin autoantibody(IAA) were measured. The clinical characteristics,biochemical parameters and serum peptide were compared among four groups. Results Compared with group 1,2 and 4,group 3 showed the oldest age at onset,and higher levels of BMI,hypertension,serum triglyceride,cholesterol,fasting and postprandial C-peptide. Patients in group 2 had the youngest age at onset,the lowest level of serum C peptide. The phenotypes of patients in group 1 and group 4 were intermediate between group 2 and group 3. Conclusions About 39.7% of patients with KPD have positive islet auto-antibodies. Patients with KPD show significantly different levels of ?-cell function,clinical characteristics and biochemical parameters,which may need different therapeutic strategies.

Topical photodynamic therapy (PDT),a highly effective,safe and non-invasive therapeutic method,exerts good therapeutic effects on various diseases in dermatology,such as actinic keratosis,condyloma acuminatum,acne,and so on.The major drawback of PDT is pain during the treatment.Some patients have to interrupt or terminate the treatment because of pain intolerance.Some progress has been made in the management of PDT-related pain.It has been revealed that multiple factors are associated with PDT-related pain,including individual factors,lesion characteristics,therapeutic parameters (such as light sources,photosensitizers).Many methods can be used to manage PDT-related pain,including local cooling,oral analgesics,two-step irradiance protocol,topical anesthesia,injection anesthesia,inhalation anesthesia,transcutaneous electric nerve stimulation,hypnosis.

Objective To discuss compatibility regularity of Banxia Xiexin Decoction adjusting gastric mobility. Methods Ninty healthy SD male rats were divided into normal group (10 rats) and model group (80 rats). Rat models of electrogastric dysrhythmias were established. After the evaluation of gastric electrophysiology, Banxia Xiexin Decoction were divided into Xinkai, Kujiang, Ganbu, Xinkaikujiang, Xinkaiganbu, and Kujiangganbu groups according to the compatibility regularity of Banxia Xiexin Decoction, 10 rats for each group. Rats in each medication administration group received gavage with same concentration but different volume for 4 weeks. Each group was analyzed for gastric electrical parameters after administration. The expressions of Cx43 and Cx43 mRNA in the gastric tissue of rats in each group were analyzed by immunohistochemistry and real-time fluorescent quantitative PCR. Results Compare with the normal group, the expressions of Cx43 and Cx43 mRNA in the gastric tissue of rats increased significantly in the model group. Compared with the model group, variable coefficient of electrogastric slow wave frequency in all medication administration groups decreased obviously. Banxia Xiexin Decoction and its components had decreased the expression of Cx43 and Cx43 mRNA to some extent, among which Xinkaiganbu group had best effects. Conclusion The mechanism of Banxia Xiexin Decoction adjusting gastric motility maybe related to its function of decreasing the expressions of Cx43 and Cx43 mRNA, as to adjust disordered electrogastric rhythm.
