Objective To compare the efficacy and safety of three regiments of transient intensive insulin therapy for type 2 diabetes mellitns: thrice preprandial injection of premixed insulin aspart 30, thrice preprandial injection of insulin aspart and injection of glargine at bedtime, thrice preprandial injection of regular insulin and injection of NPH at bedtime. Methods Patients were randomly divided into 3 groups, treated with 3 kinds of intensive insulin therapy. After achieving the target goal, continuous glucose monitoring system was used to compare the blood glucose level, therapeutic time, dosage of insulin, occurrence of hypoglycemia. Results Detected by continuous glucose monitoring system, there was no statistical difference in average blood glucose [(8.3±2.1,7.5±1.9, 6.8±0.8) mmol/L, P > 0.05], blood glucose area under curve 3 hours (AUC1-3) after breakfast, therapeutic time [ (8.3±2.5, 9.1±3.8, 8.4±1.7)d, P > 0.05], dosage of insulin [(0.63± 80%, P > 0.05) among three kinds of transient intensive insulin therapy. There were no patients complaining of hypoglycemic symptom. Conclusion The short-term efficacy and safety among three intensive insulin therapeutic methods are similar. More attention should be paid to monitor the blood glucose during sleep.

PURPOSE: To analyze the correlation of polymorphisms of toll-like receptor 7 (TLR7) (rs179009) and toll-like receptor 9 (TLR9) (rs187084) in hepatitis C virus (HCV) infections in the Han population. MATERIALS AND METHODS: The genotypes of TLR7IVS2-151 in HCV infection were detected by Sanger sequencing using polymerase chain reaction-restriction fragment length polymorphism to determine the TLR9 T-1486C single nucleotide polymorphisms (SNP) for all enrolled patients. RESULTS: We found no significant difference between males with spontaneous clearance of HCV versus those chronically infected [chi2=2.71, p=0.10, odd ratios (OR)=0.58, 95% confidence interval (CI) 0.31-1.11]. However, significant differences were found for the distribution of TLR7 (rs179009) in females (chi2=9.46, p=0.01). In females, a significant difference was also found between chronic hepatitis C and those with spontaneous clearance of HCV in terms of TLR7 IVS2-151G/A allele frequencies (chi2=9.50, p=0.00, OR=0.46, 95% CI 0.28-0.75). In HCV-infected patients, no significant association was found between the frequency of TLR9 genotypes and alleles. CONCLUSION: The site of TLR7 IVS2-151 (rs179009) G/A may be a factor for susceptibility of chronic HCV in the female Han population. TLR9T-1486C (rs18084) SNP may not play a major role in HCV infection. However, individual risk profiles for HCV infection did vary by sex and this relationship should be further investigated.

OBJECTIVETo evaluate the clinical efficacy and safety of transperineal ultrasonic therapy for chronic prostatitis (CP) by analyzing the scores of NIH-CPSI and the results of prostate fluid routine examination.

METHODSWe conducted a randomized, double-blind, multi-centered trial on 96 CP patients that met the inclusion criteria. We divided the patients into groups A (trial) and B (control) of equal number, the former treated by transperineal ultrasound, while the latter with the same machine but no ultrasound waves, 10 min a time qd alt for 2 weeks. Then we evaluated the therapeutic effect and safety by comparing the scores of NIH-CP-SI and counts of white blood cells (WBC) and lecithin corpuscles (LC) in the prostate fluid between the two groups before and after treatment.

RESULTSThe total effectiveness rate was 70.83% in group A and 25% in group B (P < 0.01). The scores on prostate pain, urinary symptoms and quality of life as well as the total NIH-CPSI score were significantly improved in group A as compared with pretreatment (P < 0.05), and so were the prostate pain score and total NIH-CPSI score in group B (P < 0.05). Statistically significant differences were observed between the two groups in the scores on prostate pain and urinary symptoms and total NIH-CPSI score after treatment (P < 0.05), but not in any of the NIH-CPSI scores before treatment (P > 0.05), nor were there any significant differences in the counts of WBCs and LC either between the two groups or within each group before and after treatment (P > 0.05). Two patients experienced adverse events in group A, and 1 in group B (P > 0.05).

CONCLUSIONTransperineal ultrasonic therapy is highly effective for CP, especially in relieving prostate pain. With its advantages of safety, easy operation and high acceptability, it deserves a wider clinical application.

OBJECTIVETo probe into the morphological and histological characteristics of the telencephalon of Onychodactylus fischeri, and to enrich the comparable neurobiology.

METHODHE-staining method was used to describe the characters of the telencephalon of Onychodactylus fischeri.

RESULTSThe olfactory bulb of Onychodactylus fischeri locates in the rastral and lateral to the cerebral hemisphere, and six distinct layers can be identified from the lateral to the medial, quite similar to Batrachuperus tibetanus and Hynobius leechii. In the cerebrum, the primordial hippocampus developed better than the primordial piriform. The former belongs to archipallium and the latter is paleopallium. Ventral to the primordial hippocampus there is a septal area which cannot be divided into medial and lateral parts. In the ventrical wall, there is neither medial limiting sulcus nor lateral limiting sulcus to separate the primordial hippocampus and the septal area, or the primordial piriform and the corpus striatum. The corpus striatum of Onychodactylus fischeri is paleostriatum. There is choroids plexus anterior in the lateral ventricle. The cell group that located at two sides of the third ventricle is the amygdale. Besides, the shape and size of neurons within the telencephalon are poorly differentiated.

CONCLUSIONOnychodactylus fischeri is a relatively primitive type in the amphibian. The present data will help us to further understand the nerve system of tailed amphibian.

BACKGROUNDUp to now there have been no satisfactory drugs to treat psychiatric disorders, and now bioactive compound from entomagenous fungi (BCEF0083) is a new type of bioactive compound from entomopathogenic fungi. Our previous investigations have shown that BCEF has an inhibition effect on monoamine oxidase. So, BCEF may be a latent antidepressant. This study aimed at observing the antidepressant effects and its mechanism of BCEF in the chronic unpredictable stress models in mice.

METHODSThe antidepressant effects of BCEF were examined on the chronic unpredictable stress models in mice. Sixty mice were randomly divided to six groups. Animals were housed and isolated except saline group. Mice were exposed to different stressors per day randomly from day 1 to day 21. Body weight were weighed on day 1, day 10 and on day 21 during the 21-day stress procedure. Awarding response was detected by using method of calculating the 24-hour consumption of saccharum water. Step through test was used to evaluate the behavioral response. AVP contents in plasma were also detected by using radioimmunoassays.

RESULTSChronic unpredictable stress resulted in a significant decrease of the body weight and could apparently cause escape behavior disturbance and gradual reduction of sensitivity to reward in animal models. Drug treatment (BCEF 25, 50, 100 mg/kg) could significantly ameliorate the decreased body weight and effectively reverse the escape behavior disturbance. The gradual reduction of sensitivity to reward, the anhedonic state, was also effectively reversed by BCEF. BCEF (50, 100 mg/kg) could also effectively restore the AVP content in the plasma.

CONCLUSIONSThis evidence suggests that BCEF can effectively inhibit the depression behavior and show strong antidepressant effect. BCEF can effectively restore the plasma AVP release and this may be an important mechanism of its antidepressant effect.

This study is to determine age-specific prostate-specific antigen (PSA) distributions in Chinese men without prostate cancer (PC) and to recommend reference ranges for this population after comparison with other studies. From September 2003 to December 2006, 9 374 adult men aged from 18 to 96 years agreed to participate in the study. After all cases of PC were excluded, 8 422 adult men participated in statistical analysis and were divided into five age groups. Simple descriptive statistical analyses were carried out and quartiles and 95th percentiles were calculated for each age group. The age-specific PSA reference ranges are as follows: 40-49 years, 2.15 ng mL(-1); 50-59 years, 3.20 ng mL(-1); 60-69 years, 4.10 ng mL(-1); 70-79 years, 5.37 ng mL(-1). The results indicate that the ethnic differences in PSA levels are obvious. The currently adopted Oesterling's age-specific PSA reference ranges are not appropriate for Chinese men. The reference ranges of this study should be more suitable to Chinese men.
