Objective To explore the changes of estrogen receptor (ER) and progesterone receptor (PR) in the endometria of pro-liferative phase in polycystic ovary syndrome (PCOS) patients. Methods Thirty-two patients who suffered PCOS combined with infertilitas feminis were enrolled in this study, and 20 cases of tubal infertilitas feminis having the corresponding time period were selected as controls. The expressions of estrogen receptor (ER) and progesterone receptor (PR) in the endometria were observed by pathological examination and immunohistochemical staining. Results The expressions of ER and PR in the PCOS group in the glands and interstitium of endometrial a-mong three different periods were not significantly different. The expressions of ER and PR in the glands and interstitium of endometrial a-mong three different periods in the control group were significantly different. There was no statistical difference in the expressions of ER, PR in the glands and interstitium of the early endometria between PCOS group and control group. The expressions of ER in the glands and inter-stitium of the middle endometrial in PCOS group was significantly lower than that of control group. The expressions of ER and PR in the glands and interstitium of the late proliferative endometrial in PCOS group was significantly lower than that of control group. Conclusion ER and PR of endometrial in the PCOS patients decreased. The cyclical of ER and PR in the PCOS patient were irregular.

Objective To investigate the effects of estrogen receptor alpha (Erα) gene polymorphism on the efficacy of ursodeoxycholic acid (UDCA) in female primary biliary cirrhosis (PBC) treatment. Methods The polymorphism of Xba Ⅰ and Pvu Ⅱ sites in No. 1 Intron of Erαgene was detected by polymerase chain reaction-restriction fragment length polymorphism in 65 female patients with PBC. The patients were treated with UDCA tablets daily (13-15 mg·kg-1 · d- 1,divided for 3 times oral taking). The variations of patients' serum total bilirubin (Tbil), alanine aminotransferase (ALT), alkaline phosphatase (ALP), γ-glutamyle transpeptidase (GGT) were followed up totally for 24 months. Results Totally the complete follow-up data had been obtained in 60 patients. Four indicators of XX or PP type patients slowly declined till the end of follow-up point still had not reached the effective treatment standard. Four indicators of Xx type patients were also slowly declined, while the effective treatment standard was achieved till the end of follow-up. Four indicators of Pp/pp or xx type patients were rapid declined to the effective treatment standard. The effective rate of UDCA in PBC treatment was 75.0％ (45/60). The distribution difference of Pvu Ⅱ between the UDCA treating effective group and the ineffective group in PP, Pp, pp types patients and XX、Xx、xx types patients was statistic significant (x2 = 12.13、 P = 0.003 and x2 = 9.95 、 P = 0.007 respectively). The distribution difference of Xba Ⅰ between the effective group and the ineffective group with UDCA treatment in XX, Xx and xx types patients was also significant (P ＜0.05). The effective rate of Pp, pp, Xx, xx types patients [82.61％ (19/23)、80.65％ (25/31) 、9/14、83. 33％ (35/42) respectively] was higher than PP and XX types patients (1/6 and 1/4 respectively).Conclusion Erα gene polymorphism influenced the efficacy of ursodeoxycholic acid in treating primary biliary cirrhosis.

Objective: To compare the fracture resistance of pulpless teeth restored with three types of post core.Methods: A total of 21 recently extracted sound upper incisors were randomly distributed into 3 groups. In group A the teeth were restored with prefabricated glass fiber post and composite core; in group B with custom cast titanium alloy post and core; and in group C with Ni Cr alloy dowel core. The size and shape of posts were identical in the 3 groups. All teeth were fully covered with Ni Cr alloy cast crown. Fracture resistance was measured by applying a point force at 130 degrees to the long axis of the teeth. Results: Mean fracture threshold was (276.6?15.1)N in group A, (394.7?29.1)N in group B and (373.4? 53.8 )N in group C. In group B and C, however, fracture always affected the tooth itself,whereas in group A,the core always failed first. Conclusion: Fiber reinforced composite(FRC) post may meet the clinical need, FRC post combined with composite core may prevent tooth root from fracture.

Objective To evaluate the applicability of the simplified equation of MDRD to predict glomerular filtration rate(GFR)from serum creatinine in Chinese patients with chronic kidney disease(CKD),and refit the MDRD equation parameter estimates with Chinese patients data.Methods A total of 760 hospitalized CKD patients were investigated from 2002 to 2005.Patients'sex,age,height and body weight were recorded;plasma creatinine and ~ 99m Tc-GFR(standardized by body surface area)were measured in all patients;GFR was estimated with simplified equation of MDRD and Cockcroft-Gault;the accurancy of estimated GFR with MDRD and CG were compared with~ 99m Tc-GFR in different stage of CKD.Totally 670 patients were randomly selected as the training sample,the remaining 90 patients constituted the validation sample.We used stepwise multiple regression to refit the equation of MDRD and the regression models were developed by using the training sample.The refitting equation was then tested and compared with the other equation in the validation sample.Results (1)Both the MDRD and CG-GFR prediction equations seemd to systematically underestimate GFR,but the accurancy of MDRD equation was better than CG-GFR in stage Ⅰ~Ⅲ of CKD.(2)The bias of estimated GFR(MDRD or CG-GFR equation)with ~ 99m Tc-GFR was lower in stage Ⅰ~Ⅲ than in stage Ⅳ~Ⅴ of CKD.(3)Refitting of the MDRD equation parameter estimates to Chinese patients data set resulted in the following prediction equations:GFR=234.96?(Scr)~ -0.926 ?(Age)~ -0.280 ?0.828(Female).(4)Comparing with~ 99m Tc-GFR,the bias of estimated GFR calculated by the refitting MDRD equation was lower than that of estimated with MDRD or CG especially in the stage Ⅳ~Ⅴ of CKD in Chinese patients.Conclusion the simplified equation of MDRD can estimate GRF accurately,but the equation must be refitted in Chinese patients.

Objective To observe the clinical efficacy of Lao Shi Jiu (moxibustion at a group of ten acupoints) plus Wu Zhu Xiang Sha Liu Jun decoction in treating chronic gastritis due to deficient cold in spleen-stomach. Method Ninety patients with chronic gastritis due to deficient cold in spleen-stomach were randomized into a moxibustion-medication group and a Western medication group by using the random number table, 45 cases each. The moxibustion-medication group was intervened by Lao Shi Jiu plus Wu Zhu Xiang Sha Liu Jun decoction, while the Western medication group was prescribed with conventional medications. The clinical efficacy and changes in symptoms were observed after the intervention. Result The total effective rates were respectively 88.9% and 75.6% in the moxibustion-medication group and Western medication group, and the rate in the moxibustion-medication group was significantly higher than that in the Western medication group (P<0.05); the gastroscopy-based total effective rates were respectively 91.1% and 77.8% in the moxibustion-medication group and Western medication group, indicating that the moxibustion-medication group was superior to the Western medication group (P<0.05); the improvement of stomachache in the moxibustion-medication group was more significant than that in the Western medication group (P<0.05). Conclusion The moxibustion-medication group is superior to the Western medication group in comparing the clinical efficacy and improvement of symptoms in treating chronic gastritis due to deficient cold in spleen-stomach.

Objective To investigate the hemostasis effect of alginate dressing for puncture point bleeding after peripherally inserted central catheter (PICC) by ultrasound-guided modified Seldinger technique (MST).Methods Between November 2013 and May 2016, 538 cases of cancer in our department underwent PICC, including 270 cases from November 2013 to February 2015 selected as control group (after PICC was successfully placed, sterile gauze and 3M transparent film were used to fix the puncture point) and 268 cases from March 2015 to May 2016 selected as observation group (after PICC was successfully placed, alginate dressing, sterile gauze and 3M transparent film were used to fix the puncture point).The patients in both groups were given 20 minutes of pressure for puncture point and elastic bandage compression fixation for 24 h.The degree of puncture point bleeding and times of dressing change in 24 h and 24-72 h between the two groups were compared.Results In the observation group, mild, moderate, and severe bleeding was seen in 232 cases, 34 cases, and 2 cases within 24 h, and in 242 cases, 25 cases, and 1 case between 24-72 h, respectively.In the control group, mild, moderate, and severe bleeding was seen in 12 cases, 196 cases, and 62 cases within 24 h, and in 21 cases, 212 cases, and 37 cases between 24-72 h, respectively, with significant differences (Z=-18.647, P=0.000;Z=-18.768, P=0.000).In the observation group, there were zero, once, twice, and ≥3 times of puncture point dressing change in 232 cases, 33 cases, 3 cases, and 0 case within 24 h and in 242 cases, 25 cases, 1 case, and 0 case between 24-72 h, respectively.In the control group, there were zero, once, twice, and ≥3 times of puncture point dressing change in 12 cases, 196 cases, 51 cases, and 11 cases within 24 h and in 21 cases, 209 cases, 37 cases, and 3 cases between 24-72 h, respectively, with significant differences (Z=-18.560, P=0.000;Z=-18.755, P=0.000).Conclusion The hemostasis effect of alginate dressing for puncture point bleeding after ultrasound-guided PICC by MST is satisfactory.
