Objective To explore the relationship of estradiol(E_2),monoamine neurotransmitters 5-hydroxytryptamine(5-HT),dopamine(DA)and postpartum depression.Methods Totally 342 women within 42 days after childbirth were assessed with Edinburgh postnatal depression scale(EPDS),Beck depression inventory(BDI),and general health questionnaire(GHQ).Above or equal to 13 of overall score of EPDS was the diagnosis standard of postpartum depression,and the women tested were divided into depression group and normal group accordingly,using the reagent box of radio immunoassay to test estradiol and 5-HT and DA level in the serum.Results(1)Incidence:the incidence of postpartum depression was 16.7%(57/342).The highest incidence occurred in patients above 35(22.2%);the incidence among women under 23 years old was lowest(12.5%),with a significant difference between them(P0.05). Conclusions Evaluation scales such as EPDS,BDI,and GHQ should be used to screen for postpartum depression.The measurement of estradiol and monoamine neurotransmitter(5-HT,DA)level can be used as biological objective indicators for prevention and treatment of postpartum depression.

Objective To study the mechanism of hyperintensed signal at interpeduncle region in meseneephalon on DWI with diffusion sensitive gradient(Gd)applied perpendicular to the slice direetion (DWIs).Methods MRI scanning was centered at interpeduncle region.and the protocols were as follows:(1)With electrocardiograph(ECG)triggering,DWIs was acquired during systole or diastole periods respectively.(2)To observe the shape of hyperintense signal,DWIs with various slice directions was applied,which was set parallel to skull base,along Y axis,or along the oblique line between Y and Z axis with 30°to Z axis.(3)Fiber tracking was performed with the hyperintense signal as"seed"region,fractional anisotropy(FA)and ADC were derived from(multiple directions diffusion weighted imaging,MDDW).FA and ADC of hyperintease region were compared with those of the nearby fiber by using pair t-tesL Results Signal intensitv of hyperintense region on DWIs were 2296.28±38.19 and 153.81±37.91 for b=0 and b=1000 at systole period.while they were 295.36±38.84 and 154.03±37.52 at diastole period.No staffstical difference wag demonstrated between them(t=1.34,0.62,P＞0.05).The ADC valus on DWIs acquired during systole and diastole periods were(6.07±2.20)×10-4and(6.69±1.44)×10-4 mm2/s respectively.There was rio statistical difference between them(t=0.94,P＞0.05).DTI fiber tracking verified that the hyperintense region located at the decussation of superior eerebelum peduncle(SCP)in mesencephalon.It was in long and narrow heart shape or rectangular shape on DWIs.The shape depended on the direction of Gd The ADC value derived from MDDW at hyperintense region and the fiber below were(10.61±3.42)×10-4 and(9.24±2.21)×10-4 mm2/s respectively.No statistical difference was demonstrated between them(t=0.61.P＞0.05).While,the FA at hyperintensed region 0.43±0.13 was less than that of the fiber below 0.61±0.08(t=8.32.P＜0.05).Conclusions The shape of the hyperintense region on DWIs depends on the direction of Gd.The cardiac period has no effects on the hyperintense signal at peduncles,which may be attributed to the anisotropy of SCP decussation in mesencephalon.

Objective To explore the effective therapeutic methods for hepatolithiasis.Methods We retrospectively analyzed the clinical material of 178 hepatolithiasis patients who underwent surgical therapy.Among the 178 patients,107 patients were treated with T-tube drainage(including 7 patients with left hepatic lobe or quadlrate lobe resection),and 71 patients were treated with bile duct-intestinal anastomosis(including 11 patients with left hepatic lobe or quadrate lobe resection).Results Recurrence rate of postoperative angiocholitis in the two groups was 49.5 % and 24 % respectively,and the reoperation rate was 28.7 % and 8 % respectively.Conclusions The key to prevent recurrent angiocholitis and reduce the reoperation rate is to relieve biliary tract stricture,remove the focus of infection and provide unobstructed bile duct drainage.

Objective To study the clinical characters,diagnosis and principles of treatmentof acute pancreatitis during pregnancy.Methods Forty-eight cases of acute pancreatitis during pregnancy treated in the recent 8 years were retrospectively analyzed,38 cases had non-surgical treatment(of which 36 cases were cured);10 cases had surgical treatment to remove necrotic tissue and mainly termination of pregnancy.Results Most of the cases in this group had simple pancreatitis,which accounted for 64.58%(31/48).There were 5 cases of maternal(10.42%) death and three cases of fetal(6.25%) death,and all were in patients with severe pancreatitis.Fatality rate of pregnant women with severe pancreatitis was 29.41%.Conclusions Acute pancreatitis during pregnancy is a serious disease with low prevalence rate,but has high fatality rate,and is the primary cause of death in acute abdomen of pregnancy.Nonoperative treatment is the first choice of treatment in this condition.In severe cases,timely surgical intervention is warranted,and the surgical indications should not be altered because of the pregnancy.The safety of both the pregnant woman and the fetus must simultaneously be kept into mind during therapy.

Objective To evaluate the effectiveness of MGIT liquid medium fluorescence instrument manual interpretation method for rapid detection of Mycobacterium. Methods Two hundred sputa with newly diagnosed tuberculosis patients were collected from October 2008 to January 2009 in the district hospitals in Shanghai. Of these 200 sputa, 67 sputa were positive AFB, 133 were negative. All the sputa were isolated by L-J, BacT / Alert 3D system and MGIT liquid medium methods. Results Of the 200 sputa specimens,105(52. 5% ) were isolated as Mycobacterium strains. The positive culture rate of the MGIT, BacT/Alert 3D and L-J method was 49. 5% ( 99/200 ), 48. 0% (96/200) and 45.0% ( 90/200), respectively. The MGIT culture positive rate was significantly higher than that of L-J method (x2 = 5.40, P = 0. 020 1 ). Of the 133 sputa with negative AFB, the positive culture rate was 24. 8% ( 33/133 ), 23. 3% ( 31/133 ) and 18. 8% (25/133) with MGIT, BacT/Alert 3D and L-J method, respectively. The MGIT culture positive rate with the AFB negative sputum was significantly higher than that of L-J method (x2 = 5. 33, P = 0. 020 9 ).The median time of detection with MGIT, BacT/Alert 3D system and L-J method was 11 days, 15 days and 22 days, respectively. Comparing the median time of detection of MGIT with BacT/Alert 3D, the difference was statistically significant ( Z = 3.414 ,P ＜ 0. 01 ). Comparing the median time of detection of MGIT with L-J method, the difference was statistically significant (Z =7.083,P＜0. 01).Conclusions MGIT liquid medium manual method is a rapid detection method of Mycobacterium with a high positive detection rate, and do not need expensive equipment This method may suitable to resource limited medical institutions due to its low cost and short round time.

Objective To retrospectively study pathological characteristics of 1561 patients with colorectal cancer in Nanchang area.Methods Analysis was made regarding the results of colonoscopy and pathological examination in patients from 1990 to 2004.Results Totally 21 853 patients received colonoscopy during the period,and 1561 patients were diagnosed as colorectal cancer.The overall diag- nostic yield was 7.1%.The average age diagnosed was 52 years old.Ratio of male to female was 1.4: 1.The lesion located in rectum accounted for 43.4%.The percentage of cancer in left colon was higher than that in right side (30.5% vs 26.1%,P＜0.05).The proportion (57.5%) of patients with rectal can-cer under 30 years old was the highest in all patients with rectal cancer.Cancer located in sigmoid colon and left side of the colon increased with age.Well and moderately differentiated adenocarcinoma was observed in 83.6% of the patients.Comparing the clinical characteristics of every five years,increasing diagnostic yield was noted from 1990 to 1999,hut the decreased trend was found in last five years.The propor- tions of rectal cancer was also increased in the last fifteen years,and overall proportions of cancer located in left side of colon was decreased.Conclusions The overall diagnostic yield of colorectal cancer in Nanchang area was lower than other province,especially rectal cancer.The proportion of cancer of left side of colon was increased with age.The well and moderately differentiated adenocarcinoma was found increasing in the last fifteen years, while the poorly differentiated adenocarcinoma was decreased.

OBJECTIVETo observe and evaluate the phytoestrogenic effects and its mechanism of psoralen in estrogen receptor (ER) alpha and beta positive T47D and ishikawa cells.

METHODThe proliferation rate of T47D influenced by 1 x 10(-5) mol x L(-1) to 1 x 10(-9) mol x L(-1) psoralen and that of Ishikawa influenced by 1 x 10(-6) mol x L(-1) and 1 x 10(-7) mol x L(-1) psoralen were analyzed by MTT assay. PR mRNA expression in T47D was quantified by RT-PCR assay. Estrogen receptor antagonist ICI 182, 780 was employed as a tool. ER-alpha and ER-beta expression of T47D was measured by flow cytometry.

RESULTThe proliferation rates of T47D cells treated with 1 x 10(-5) mol x L(-1) to 1 x 10(-7) mol x L(-1) psoralen and ishikawa cells treated with 1 x 10(-6) mol x L(-1) to 1 x 10(-7) mol x L(-1) psoralen were increased significantly. The RT-PCR result showed that 1 x 10(-7) mol x L(-1) and 1 x 10(-6) mol x L(-1) psoralen could increase PR expression in T47D cells. The above effects could be blocked by ICI 182,780. Psoralen could also induce the augment of ER-alpha and ER-beta expression in T47D cells significantly.

CONCLUSIONPsoralen has phytoestrogenic effects. The effects are attained through ER pathway.
