OBJECTIVE:To study the distribution of dosage form of drugs used for outpatients in a general hospital.METHODS:The general information of the outpatients in a general hospital,the total number of the varieties of the prescription drugs as well as the average number for each visit,the rate of using injection for every one hundred patients,and distribution of form of prescription drugs etc were analyzed statistically.RESULTS:Leading the first 5 places on the list of distribution of dosage forms of drugs used for outpatients were tablet,injection,capsule,granule and solution for oral use.Of the total varieties of prescription drugs,drugs taken orally,drugs for injection and drugs for external use stood at 81.07%,13.05%,and 5.88% respectively.CONCLUSION:The use of new variety of drugs such as specific tablets and capsules was little for outpatients in the general hospitals,which deserve to be widely used.

In this study, endogenous digoxin-like substance (EDLS) in the plasma was measured by radioimmunoassay in patients with congestive heart failure The EDLS levels were significantly increased in patients with heart failure and were positively correlated correlated with the heart function state, Na~+/K~+-ATPasc activity in red cells and the electrolyte change in blood cells. We believed that digoxin-like substance may participatc in the process of the compensatory mechanirsms of the heart failure.

Objective To investigate the risk factors of incidence of premature rupture of membranes and provide reference for prevention of premature rupture of membranes.Methods 890 cases of infants and maternal were studied,analyzing and screening the risk factors of premature rupture of membranes by Logistic.Results The single-factor analysis showed that the pregnant women with diabetes,pregnancy-induced hypertension,multiple preg-nancy and vaginifis had certain degree of contact with incidence of premature rupture of membranes.Multivariate Lo-gistic regression analysis showed that the multiple pregnancy and vaginitis were risk factors of incidence of premature rupture of membranes.Conclusion The multiple pregnancy and vaginitis were risk factors of incidence of premature rapture of membranes,assessment and control these risk factors could prevent and reduce the incidence of premature rupture of membranes.

Objective To study dose-response relationship for chromosome translocation and its persistence measured in human lymphocytes exposed to 60Co γ-rays.Methods The chromosome translocations in human peripheral lymphocytes were detected by fluorescence in situ hybridization using 4# and 7# combination of composite whole chromosome-specific DNA probes and Giemsa stain.Results The dose-response relationship for chromosome translocation induced by 60Co γ-rays in vitro could be described by the function:Y=0.0030+0.0134D+0.0165D2.The frequencies of chromosome translocations induced by 0.5 and 2 Gy γ-irradiation did not diminish over time,so it exhibited excellent persistence.Conclusions The results indicate that retrospective dose-reconstruction can be accomplished using chromosome translocation frequency.

Mango leaves have been widely used in the clinical practice for thousands of years in traditional Chinese medicine.Mangiferin,an effective constituent in the mango leaves,has multiple pharmacological actions involved in some basic pathological processes,such as inflammation,oxidative injury,tumor growth,micro-organism infections,metabolic regulations,and immunological regulations.The pharmacological effects of mangiferin from some published data are reviewed in this article.

Objective To discuss the clinical features,management,pregnancy outcome and prognosis of obstetric mirror syndrome.Methods The clinical data of 12 cases with obstetric mirror syndrome at Shenzhen Maternity and Child Healthcare Hospital from April 2008 to December 2010 were collected to retrospectively analyze the clinical features, management,pregnancy outcome and prognosis.Results ( 1 ) Etiology:12 cases with obstetric mirror syndrome included 9 cases of Bart's hydrops fetalis,2 cases with fetal complicated congenital cardiac anomalies,and 1 case of unknown etiology.(2)Gestational age at diagnosis and at delivery:gestational age at diagnosis ranged from 28 to 36 weeks [ mean (31.5 ±4.7) weeks],and gestational age at delivery ranged from 28+3 to 38 weeks [ mean (32.9 ±2.9)weeks].There were no significant differences between the gestational age at diagnosis and at delivery in consistented with severe preeclampsia group and mild preeclampsia group [ (31.8 ± 2.3 ) weeks vs.(30.9 ± 7.2) weeks,(32.5 ± 2.3 ) weeks vs.(33.5 ± 3.9 ) weeks,P ＞ 0.05 ].( 3 ) The patients with obstetric mirror syndrome can present a preeclampsia-like syndrome:maternal extremity edema in 12 cases,headache and visual disturbance in 1 case,proteinuria in 11 cases,elevated blood pressure in 5 cases,elevated uric acid in 9 cases,hypoproteinemia in 12 cases,elevated creatinine in 3 case,elevated liver enzyme in 1 case,thrombocytopenia in 2 cases.The major complications included 1 case of HELLP syndrome,acute pulmonary edema,placental abruption,amnionic fluid embolism,DIC respectively,3 cases of acute kidney failure and 6 cases of postpartum hemorrhage.(4) Sonographic findings:① Hydrops fetalis:fetal ultrasound revealed pleural fluid,fetal ascites,skin edema,scalp edema,encephalocolele enlargement, hydropericardium and increased cardio-chest ratio.②Placenta megaly:the placental pathological examination revealed edematous and large in 12 cases.Placental thickness was beyond 4 cm in all cases [ (6.3 ± 1.9) cm ].③Hydramnios:hydramnios could be found in 11 cases [ amniotic fluid index ( 19.7 ± 3.1 ) cm ]. (5) Postnatal conditions:all blood pressure and laboratory findings including urine protein normalized within 5 to 7 days after delivery. (6) Pregnancy outcome:all 12 patients survived,however the perinatal mortality rate was 100％.Two of 12 cases with mirror syndrome underwent cesarean section,and 10 were vaginal delivery,of which 1 need uterine artery embolisom due to postpartum hemorrhage.Conclusions Obstetric mirror syndrome seems to simulate preeclampsia although there are distinguishing features,such as hemodilution,placental edema,and polyhydramnios.When the specific cause of obstetric mirror syndrome can not be identified and corrected,the decision for delivery should be made as soon as possibly.

Objective To explore the correlation of chemosensitivity in vitro of anti-cancer drugs between peripheral blood lymphocytes and tumor cells in non-small cell lung cancer of elderly patients.Methods The MTT method was used to test the sensitivity of the peripheral blood lymphocyte and the tumor cells of 52 patients with nonsmall cell lung cancer to 13 kinds of anti-cancer drugs.Results The sensitivity test in eleven drugs include CDDP,CBP,LOHP,PTX,CTX,ICTX,THP,VP-16,GEM,VCR and NVB in the peripheral blood lymphocyte were associated with that in the tumor cells.But no dependablity in two drugs,ADM and HCPT.Conclusion The peripheral blood lymphocytes could be replace tumor cells to test the chemosensitivity of anti-cancer drugs in patients with non-small cell lung cancer.

Objective To analyze and compare the emergency therapeutic methods for renal colic,and to explore the preferable way of emergency therapies for renal colic.Methods A total of 340 cases of renal colic in emergency department were randomly divided into groups A (pethidine),B (diclofenac sodium),C (phloroglucinol),and D (diclofenac sodium + phloroglucino).The average time of therapeutic effect after given 30 min in different groups was observed.Results The average time of effect in group A [(9.53 ±3.34) min],group D[(10.49 ±2.54) min],and group B[(10.51 ±2.27)min] and they were much shorter than group C [(18.51 ±4.86) min] (P ＜0.01).There was no significant difference in the effective rate among the 4 groups(P ＞ 0.05).The relapse rate of group C (11.43％) and group D (9.00％) were much lower than group A (24.59％) and group B(23.75％).There was no adverse reaction in group C.The rates of adverse reactions in group B (2.27％) and group D (2.78％) were much lower than group A (27.27％).Conclusions Diclofenac sodium combined with phloroglucinol was preferable emergency treatment for renal colic.

This study is to investigate the protective effect of mangiferin on NF-kappaB (P65) and IkappaBalpha expression in peripheral blood mononuclear cell (PBMC) in rats with cigarette smoke induced chronic bronchitis. The rat model with chronic bronchitis was established by cigarette smoke. Real-time fluorescence RT-PCR was executed for evaluating the NF-kappaB (P65) and IKkappaBalpha gene expression in mononuclear cell, and flow cytometry for their protein expression. The serum hs-CRP (high-sensitivity C-reactive proteins) and TNF-alpha (tumor necrosis factor-alpha) were detected by enzyme-linked immunosorbent assay. The histopathological score was obtained from lung tissue HE staining slides of lung tissue. The results showed that mangiferin could markedly suppress the NF-kappaB (P65) mRNA and protein expression in mononuclear cell, while promote the IkappaBalpha mRNA and protein expression. Furthermore, mangiferin could lower serum hs-CRP and TNF-alpha level, and reduce the chronic inflammatory damage of bronchiole. These results suggested that mangiferin could notably ameliorate chronic bronchiole inflammation induced by cigarette smoke, and this protective effect might be linked to the regulation of NF-kappaB (P65) and IkappaBalpha expression in mononuclear cell.

Objective To observe the clinical effects of different fluid therapies in treating severe preeclampsia complicated by ascites. Methods Between Jan. 2010 and Dec. 2012, patients with severe preeclampsia complicated by ascites in Shenzhen Maternity and Child Healthcare Hospital were included in this study. The treatment group ( n=55 ) were given intravenous drip of 6% hydroxyl starch 130/0. 4 plus furosemide, and the control group (n=52) received intravenous drip of 5%human serum albumin plus furosemide. The mean arterial pressure, respiratory rate, heart rate, oxyhemoglobin saturation, colloid osmotic pressure, hematocrit and the incidence of acute pulmonary edema were observed and compared between the two groups. Results Twenty-four hours after cesarean section, the mean arterial pressure of the treatment group was significantly lower than that of the control group, whereas heart rate and oxyhemoglobin saturation were significantly higher (all P<0. 05). The incidence of acute pulmonary edema of the control group was 17. 3%, while no patient in the treatment group developed acute pulmonary edema. On the 5th day after surgery, the hematocrit and 24 h proteinuria were significantly lower in the treatment group, while colloid osmotic pressure was higher (all P<0. 05). There was no difference in serum albumin level between the two groups (P>0. 05). The average duration of edema after treatment was significantly shorter in the treatment group [(2. 43±0. 37) d versus (3. 74±0. 59) d, P<0. 01]. Conclusion 6% hydroxyl starch 130/4. 0 plus furosemide can effectively elevate the colloid osmotic pressure, resolve edema, improve hypovolemia, sustain oxygen supply to the organs and decrease the complication of pulmonary edema in patients with severe preeclampsia complicated by ascites.
