ObjectiveTo determine the impact of lupus flares on maternal and fetal outcomes in pregnant patients with systemic lupus erythematosus(SLE).MethodsData was obtained from 46 pregnancies of 44 pregnant women with SLE.The relationship between lupus flares and pregnant outcomes,and the risk factors for adverse maternal and fetal prognosis were analyzed.T-test,X2 test or Fisher's exact test and Logistic regression were used for statistical analysis.Results① Lupus flares occurred in19(41%)pregnancies(group A) and stable lupus disease was observed in 27(59%) pregnancies(group B) during pregnancy.Compared to pregnancies in patients with stable lupus disease at the conception(n=32),pregnancies in patients with unstable lupus disease at the conception(n=8) had higher lupus flare during pregnancy( 100% vs 16%,P<0.05).(②) The common manifestations of lupus flares during pregnancy were lupus nephritis (LN) (11 cases),skin rashes (10 cases),arthritis (7 cases),and the common complication was infection ( 11 cases).(③) The incidence of premature labor,fetal growth retardation (FGR) and fetal loss in group A was 42%,47% and 26% respectively,which was significantly higher than that of the group B (7%,15% and 0 respectively)(P<0.05).There was no difference in the incidence of preeclampsia,fetal distress and neonatal asphyxia between the two groups ( 16% vs 7%,16% vs 19%,5% vs O,respectively,P>0.05).The incidence of premature labor and FGR in patients with active LN was higher than that of patients without active LN (55% vs 11%,64% vs 17%,respectively,P<0.05).(④)The binary Logistic regression analysis showed that renal impairment,hypocomplementemia,aPL and serum urea nitrogen level were independent risk factors for premature delivery,FGR,fetal loss and fetal distress.Conclusion(①) Lupus flares during pregnancy increase the incidence of premature labor,FGR and fetal loss.Active LN during pregnancy can increase the incidence of premature labor and FGR.② Renal impairment,hypocomplementemia,aPL and serum urea nitrogen level are associated with adverse fetal outcomes in pregnant patients with SLE.

OBJECTIVETo evaluate the efficacy of Wuling Capsule (WLC) in treating patients with poststroke depression.
METHODSOne hundred and eight patients with poststroke depression were randomly assigned to three groups, 36 in each. All were treated with routine medicine, but to the WLC group and the FLX group, additional WLC and fluoxetine was given respectively, while to the combined group, both of the two were given. Patients' neurological and cognitive function were estimated by HAMI) scale, MMSE scale, SSS scale and Barthel index (BI) before treatment and at 4 weeks and 12 weeks after treatment.
RESULTSHAMD score and SSS score significantly decreased (P < 0.01) while MMSE score and BI score significantly increased (P <0.05) in all the three groups, but the improvement in decrease of HAMD score and in increase of BI score in the combined group was more significant than those in the other two groups respectively (P<0.05).
CONCLUSIONSWLC is effective in treating patients with poststroke depression and shows synergism with fluoxetine.

OBJECTIVETo develop a chitosan (CH)/polyethylene glycols succinate acid (PEG-SA)-mediated mitomycin C (MMC) delivery system and investigate its drug release characteristics in vitro and its effect against scar tissue adhesion in vivo.
METHODSMitomycin C loading in the composite CH/PEG-SA/MMC films was determined using ultraviolet. The freeze-dried films were dispersed in 1 ml PBS (pH7.4) and mitomycin C release in vitro was determined according to the mitomycin C concentration-UV value standard curve. The influence of the film structure on the drug release was evaluated. The drug delivery system was then implanted in SD rats, and 4 weeks later, immunohistochemical and histological examinations were carried out to assess the therapeutic effect on epidural scar tissue.
RESULTSThe linear regression equation of the mitomycin C concentration-UV value standard curve was y=0.593x(3)-2.563x(2)+25.944x-0.236 (R(2)=1.000). The film demonstrated good drug delivery capability, and 20 mg of the samples in PBS showed a peak mitomycin C release after 12 days of 14.9616 microg/ml, which was higher than the ID(50) of mitomycin C (10.4713 microg/l) to the fibroblasts. On days 18 and 32, another two drug release peaks occurred (14.4824 microg/ml and 11.4092 microg/ml, respectively), followed by maintenance of slow release. Till day 60, the accumulative mitomycin release reached 0.1793 microg/ml, and the loaded drug was ultimately completely released. Significant differences were noted in the hydroxyproline content in the scar tissues of different groups (F=12.085, P=0.000), and the CH/PEG-SA/MMC DDS reduced the amount of scar tissue and promoted its orderly alignment to control potential scar hyperplasia that may compress the spinal cord and nerve roots.
CONCLUSIONThe composite film for drug delivery possesses good flexibility and mechanical properties and allows sustained drug release of mitomycin C to prevent epidural scar tissue adhesion following lumbar laminectomy.

Objective To study the application value of dynamic monitoring of blood pressure in the prevention and treatment of elderly hypertension. Methods 519 hypertensive patients from December 2017 to December 2018 were monitored with ambulatory blood pressure monitoring, and were divided into the elderly group (≥60 years old, 264 cases) and the control group (<60 years old, 255 cases). The results of ambulatory blood pressure monitoring in two groups were analyzed, which inclued the circadian rhythm of blood pressure, blood pressure, pulse pressure, coefficient of variation of blood pressure, blood pressure load value, average heart rate and morning blood pressure surge. Results The incidence of abnormal circadian rhythm of ambulatory blood pressure in the elderly group was 76.5%. Compared with the control group, there were differences in the indexes of diastolic blood pressure (DBP), diastolic blood pressure load value (DBPLV), pulse pressure (PP), 24 h average heart rate (24 hAHR), systolic blood pressure coefficient of variation (SBPCV), 24 h diastolic blood pressure coefficient of variation (24 h DBPCV) and morning diastolic blood pressure surge (MDBPS) between the two groups(all P<0.05). There were differences in 24 h systolic blood pressure (24hSBP), night systolic blood pressure (nSBP), night diastolic blood pressure (nDBP), night pulse pressure (nPP), day systolic blood pressure load value (dSBPLV), ninght systolic blood pressure load value (nSBPLV), 24 h SBPCV, 24 h dDBPCV and other indicators among different blood pressure types in the elderly group (all P<0.05). Conclusion Ambulatory blood pressure monitoring indicators have important guiding value for the prevention and treatment of elderly hypertension.

Laryngeal and hypopharyngeal carcinomas are common malignant tumors of the head and neck, and the incidence of both is increasing. Laryngopharyngeal reflux refers to the retrograde flow of gastric contents into the larynx, oropharynx, and/or nasopharynx. It remains controversial whether laryngopharyngeal reflux is a risk factor for laryngeal and hypopharyngeal cancers. The refluxing substances mainly include hydrochloric acid, pepsin, and occasionally bile acids and bile salts, as well as bacteria that colonize the gastrointestinal tract. Loss of epithelium in the mucous membrane of the larynx and hypopharynx is thought to be caused by pepsin. Here, we review the relationships between laryngopharyngeal reflux and both laryngeal and hypopharyngeal carcinomas, as well as the significance of pepsin, methods of clinical detection, and the mechanism of carcinogenesis.

A simple, reliable and sensitive liquid chromatography-isotope dilution mass spectrometry (LC-ID/MS) was developed and validated for quantification of olanzapine in human plasma. Plasma samples (50 microL) were extracted with tert-butyl methyl ether and isotope-labeled internal standard (olanzapine-D3) was used. The chromatographic separation was performed on XBridge Shield RP 18 (100 mm x 2.1 mm, 3.5 microm, Waters). An isocratic program was used at a flow rate of 0.4 m x min(-1) with mobile phase consisting of acetonitrile and ammonium buffer (pH 8). The protonated ions of analytes were detected in positive ionization by multiple reactions monitoring (MRM) mode. The plasma method, with a lower limit of quantification (LLOQ) of 0.1 ng x mL(-1), demonstrated good linearity over a range of 0.1 - 30 ng x mL(-1) of olanzapine. Specificity, linearity, accuracy, precision, recovery, matrix effect and stability were evaluated during method validation. The validated method was successfully applied to analyzing human plasma samples in bioavailability study.
