Objective:To investigate the expression of chemokine receptor in eupotic and ectopic endometrial tissues of women with endometriosis, and in endometrium of women without endometriosis.Methods:Normal endometrium, eutopic endometrium and endometriotic tissues were obtained from patients with endometriosis at laparoscopy. Total RNA was then extracted using the TRIzol reagent. The expression of chemokine receptors in these tissues were analyzed by way of semi-quantitative reverse transcriptase-polymerase chain reaction.Results:Compared to normal endometrium, the eutopic endometrium expressed significantly more CCR6, CCR8, CCR9 and CX3CR1(P

The response of glueagon to the change of glucose and its relation to blood pressure in 71 eidely patients with type 2 diabetes was investigated. The results showed that the postprandial increment of glucagon in the group of patients with postprandial 2h plasma glucose increment<2.5 mmol/L was significantly higher than that in the group with plasma glucose inerement≥ 2.5 mmoi/L (P<0. 05). The postprandial increment of glucagon in patients with normal blood pressure was significantly higher than that in patients with hypertension (P<0.05). The results suggest that the decreased response of glucagon to the change in plasma glucose in elderly patients with type 2 diabetes is related to increased blood glucose and high blood pressure.

Objective To investigate effect of early enteral nutrition supplemented with probiotics on gastrointestinal motility disturbance and nutritional status in patients with severe craniocerebral trauma.Methods Forty patients with severe craniocerebral trauma were randomized into study group (18patients) and control group (22 patients).Patients of both groups received enteral nutrition via nasogastric tube at 24-72 hours after admission,but the patients of study group were also supplemented with probiotics simultaneously.Rate of abdominal distention,vomiting,gastro-oesophageal reflux,gastric retention,constipation and diarrhea were recorded during the whole study.Time to first defecation and time to targeted nutritional goals were also recorded.Prealbumin and transferrin in serum were detected at days 0,4,7,and 15 after the beginning of enteral nutrition.Length of ICU stay was compared between groups.Results There were no significant differences of the two groups in terms of rate of abdominal distention,vomiting,gastric retention and diarrhea.However,less gastro-oesophageal reflux or constipation patients were observed in study group,as compared with control group (P ＜ 0.05).Time to first defecation and time to targeted nutritional goals were shorter in study group,as compared with control group (P ＜ 0.05).Levels of prealbumin and transferrin had no significant differences between the two groups at days 0,4,and 7,but study group showed both were higher than control group at day 15 (P＜0.05).Moreover,length of ICU stay showed no significant difference between the two groups.Conclusions Compared with simple enteral nutrition,early enteral nutrition with probiotics improves gastrointestinal motility,facilitates the delivery of enteral nutrition,and further ameliorates nutritional status in patients with severe craniocerebral trauma.

OBJECTIVE:To change the drug management mode in wards,promote drug use for patients timely and rationally. METHODS:Automated dispensing cabinet(ADC)was used to manage the drugs in some wards in our hospital,and introduce its use practice from aspects of drug management mode,pharmacists'management to ADC,related measures when using ADC manag-ing ward drugs,effect evaluation after using ADC(using species of base drugs,average time of dispensing temporary medical or-ders,drug returning times in 5 wards before and after using ADC as indexes),etc. RESULTS:Drug management method was es-tablished in ADC by screening drugs into the cabinet and developing process of taking drugs out. And pharmacists had achieved drug management in wards by establishing drug lists,conducting replenishment and inventory management,developing emergency plan,enhancing supervision and inspection,etc. Compared with before using ADC,average species of base drugs in the 5 wards increased from 65.8 to 157.2;average time of dispensing temporary medical orders dropped from 24.5 min to 5.8 min;and average drug returning times in 3 months decreased from about 200 times to about 20 times(P<0.05 or P<0.01). CONCLUSIONS:Us-ing ADC in wards for drug management has not only improved use convenience of drugs in wards,working efficiency of nurses as well as pharmaceutical care quality of pharmacists,but also has changed drug management mode and promoted rational drug use of patients.

The fasting and 2 h levels of glucagon, somatostatin ( SS), and C-peptide during 75 g oral glucose tolerance test in 60 patients with type 2 diabetes and 34 normal subjects were determined. Compared with control group, the fasting levels of glucagon and SS and 2 h levels of SS after glucose loading significantly decreased,while the fasting and 2 h levels of C-peptide increased in diabetes group. The 2 h levels of these hormones were significantly higher than the fasting levels in two groups. Compared with control group, the increased folds of glucagon ( 1.40±0.48 vs 1.20±0. 30, P＜0. 05 ) and SS( 2.79±2. 17 vs 1.14±0. 22, P＜0. 01 ) levels after glucose loading were higher and that of C-peptide level ( 3.58 ±3. 10 vs 8. 33 ± 6. 99, P＜0. 01 ) was lower in diabetes group. The levels of fasting glucagon were positively correlated with that of fasting SS in two groups( both P＜0. 01 ). These results suggest that disturbance exists in hormones from α and δ cells besides the dysfunction of β cells in patients with type 2 diabetes.
