The paper analyzes the current status of and problems in the development of non-government medical institutions in Shanghai, the advantages non-government medical institutions possess and the difficulties they face in the process of development. It advances the development orientation of non-government medical institutions, arguing that it is imperative to create circumstances and conditions for fair competition, formulate perfect supporting policies, and lead non-government medical institutions to the integration of their own development with the reform and development of the medical and health cause of the country. It argues, on the other hand, that non-government medical institutions must stress simultaneously the accumulation and the operation of capital so as to have a niche in the fierce competitions of the medical market.

ObjectiveTo investigate the clinical application of tacrulimus (TAC, FK506) in children with primary nephrotic syndrome (NS). MethodsSixty-five primary NS children received routine or decreased-dosage glucocorticosteroid according to clinical NS types after hospitalization. At the same time, TAC was given orally with the dosage of 0.1 to 0.15 mg/kg, once every 12 hours, for 6 to 24 months. And the serum concentration of TAC was monitored during the course. ResultsAfter the treatment of TAC for 1 to 2 months, 65 patients were recovered with gradually reduced urinary protein, rapidly increased serum albumin, and improvement of cholesterol and triglycerides. Total remission rate was 83.1% and onset time was 7 to 54 days. Twelve cases experienced recurrence. Increased CD4, as well as 3/3 or 3/1 TAC genotype, indicated higher remission rate. Various pathological types had different remission rates or ratio, which were as follows: minimal change nephropathy (96.4%), mesangial proliferative glomendonephritis (90.0%), membranous nephropathy (2/3), membranous proliferative glomerulonephritis (3/5), focal segmental glomerulosclerosis (4/9). The patients would recover in the course of treatment under the conditions of TAC initial dose as 0.1 to 0.15 mg /kg per 12 hours and controlled serum concentration as 5 to 10 g/L. During the treatment, 12 cases appeared gastrointestinal symptoms, mainly as anorexia, nausea and vomiting, 1 abdominal pain, 2 headache, 1 tremor, 1 paresthesia, 3 insomnia, 4 transient increased Scr, 8 slightly increased NAG, 6 increased C3 and α-2 macroglobulin. The symptoms disappeared within one week or after stopping TAC. ConclusionsTAC is effective in primary NS children, even with abnormal liver function or tuberculosis infection. TAC can also be a substitute to cyclosporine A.

Objective To investigate the application of secondary prevention medication for patients with high risk of recurrent ischemic stroke in Changzhou city,analyze the reasons for decreased medication compliance,and evaluate the current secondary prevention medication.Methods We investigated 300 consecutive hospitalized patients with acute non-cardiogenic and ischemic stroke high risk.High risk of recurrent stroke was defined as ESSEN Stroke Risk Score (ESRS) ≥3.Different ESRS scales consisting of different parameters were analyzed.All of the patients received standard secondary prevention of ischemic stroke at discharge.After three months and a year follow up,antiplatelet therapy,therapy of risk factors (hypertension and diabetes mellitus),lipid lowering therapy,and medication compliance were investigated.Results Except for age (x2 =126.54,P =0.000) and previous cerebral ischemic stroke or transient ischemic attack (TIA) (x2 =21.27,P =0.000),there were no significant differences in other risk factors (hypertension,diabetes,previous myocardial infarction,heart diseases,smoke) in patients with different ESRS scale scores (all P＞ 0.05).Antiplatelet therapy utilization was 98.3％ (295/300),antihypertensive and antidiabetic drug use rates were 95.0％(255/268) and 100％(72/72),statin use rate reached to 99％ (297/300) at discharge.After three months follow up,medication compliance in hypertension and diabetes mellitus therapy was the best [88.1％(222/252)and 86.2％ (56/65)],followed by aspirin [82.0％ (228/278)],and clopidogrel [6.1％ (17/278)].The medication compliance in lipid lowering therapy was the worst [60.1％ (167/278)].After a year follow-up versus the previous three-month follow-up,the medication compliance in hypertension and diabetes mellitus therapy was increased,but had no significant difference [89.9 ％ (220/245) vs.88.1％ (222/252),93.4％(57/61)vs.86.2％(56/65),P＞0.05],and the medication compliances inantiplatelet therapy with aspirin and clopidogrel,and lipid lowering therapy were increased significantly [93.2％ (245/263)vs.82.0％ (228/278),30.8(81/263) vs.6.1％ (17/278),88.9％ (234/263) vs.60.1％ (167/278),all P＜0.01].The increment of use rate was higher in clopidogrel therapy than in aspirin therapy.Conclusions The secondary prevention medication achieves certain efficacies in patients with high risk of recurrent ischemic stroke in changzhou city.Long term follow-up and good communication between doctor and patient can effectively improve the medication compliance in secondary prevention,and can increase the use rate of antiplatelet therapy in patients with high risk of recurrent ischemic stroke.

Objective To determine the optimal pressure for facemask ventilation during induction of general anesthesia by real-time ultrasonographic measurement of antral cross-sectional area (CSA) in adult patients.Methods Sixty American Society of Anesthesiologists physical status Ⅰ or Ⅱ patients,aged 18-60 yr,with body mass index of 20-25 kg/m2,scheduled for elective operation under general anesthesia,were divided into 5 groups (n=12 each) using a random number table:P10 group,P13 group,P16 group,P19 group and P22 group.After induction of anesthesia,an oropharyngeal airway was inserted,and the patients were ventilated for a 2-min period in a pressure-controlled mode using the two-handed mask ventilation technique.The pressure for facemask ventilation was 10,13,16,19 and 22 cmH2O in P10,P13,P16,P19 and P22 groups,respectively.The antral CSA was measured using real-time ultrasonography before and after facemask ventilation.Respiratory parameters were recorded.Results Compared with group P1O,the number of patients in whom CSA＜340 mm2 after facemask ventilation was significantly decreased in P16,P19 and P22 groups,and the number of patients in whom the tidal volume ≥ 6 ml/kg was increased in P13,P16,P19 and P22 groups (P＜ 0.01).The number of patients in whom optimnal pressure for facemask ventilation was achieved was 2,10,6,4 and 1 in P10,P13,P16,P19 and P22 groups,respectively,with the most cases in group P13 (P ＜ 0.01).Conclusion The optimal pressure is 13 emH2O for facemask ventilation during induction of general anesthesia when determined by realtime ultrasonographic measurement of antral CSA,and it can ensure adequate oxygen supply and reduce gastric insufflation in adult patients.

Myricetin(MYR)was cocrystallized with caffeine(CAF)by suspension and the single crystal of MYR-CAF cocrystal was cultured by slow solvent evaporation. Cocrystals obtained by two different methods were the same in crystal form after characterization with X-ray diffraction. Structural analysis of single crystal of MYR-CAF showed that its crystal system and the space group were monoclinic and P21/n, respectively. In MYR-CAF cocrystal, 4′-OH in ring B and 7-OH in ring A of MYR interacted with CAF at(8)C=N and(2)C=O through hydrogen bonds. In comparison to the original MYR crystal, the intrinsic dissolution rate of MYR was significantly enhanced for about 17-fold after cocrystallization with CAF.

OBJECTIVE: To analyze the action of miRNA-326 on its target gene BCL-XL and the molecular mechanism of platelet apoptosis regulated by miRNAs. METHODS: Dual-luciferase vectors containing respectively the wild-type and mutant 3'-untranslated region (3'UTR) fragments of the BCL-XL gene were constructed with firefly and renilla luciferases and transfected into 293T cells. Relative fluorescence intensities of the transfected cells were measured. RESULTS: Dual-luciferase reporter gene vectors for PsiCHECK- BCL-XL -3'UTR-WT (wild-type) and PsiCHECK- BCL-XL -3' UTR-MT (variant) were respectively constructed. Relative fluorescence intensities of the 293T cells co-transfected by miRNA-326 and PsiCHECK- BCL-XL -3'UTR-WT plasmid were significantly lower compared with the control group (co-transfected by a miRNA-326 negative sequence and PsiCHECK- BCL-XL -3' UTR-WT plasmid) ( P = 0.034). The relative fluorescence intensity was also significantly reduced in cells co-transfected by miRNA-326 and PsiCHECK- BCL-XL -3' UTR-WT plasmid compared with the mutant control group co-transfected by miRNA-326 and PsiCHECK- BCL-XL -3'UTR-MT plasmid (P = 0.022). CONCLUSION miRNA-326 may participate in the regulation of platelet apoptosis by acting on the 3'-UTR of the BCL-XL gene.

OBJECTIVE To investigate the regulatory effects of couplet medicinals of Atractylodes macrocephala-Aucklandia lappa on gut microbiota and short-chain fatty acids （SCFAs） in the diarrhea-type irritable bowel syndrome （IBS-D） rats with spleen deficiency. METHODS The IBS-D rat model with spleen deficiency was induced by intragastric administration of Senna alexandrina combined with restraint stimulation. The model rats were divided into model group， positive control group （pinaverium bromide 1.5 mg/kg）， A. macrocephala-A. lappa low-dose， medium-dose and high-dose groups （0.7， 1.4， 2.8 g/kg）， with 6 rats in each group. Another 6 healthy rats were taken as the blank control group. The blank control group and the model group were given normal saline intragastrically， and other groups were given relevant drug liquid intragastrically， once a day， for consecutive 14 days. The general characteristics of rats and fecal water content were observed， and intestinal sensitivity [evaluating by abdominal wall withdrawal reflex （AWR） threshold] and the intestinal propulsion rate were determined. The serum levels of 5- hydroxytryptamine（5-HT）and SP were detected， and the pathological changes of colon tissue were observed； the protein expressions of 5-HT-3 receptor（5-HT3R）， 5-HT4R and 5-HT transporter（SERT） in colon tissue of rats were detected. 16S rRNA sequencing was performed for the feces of rats in blank control group， model group and A. macrocephala-A. lappa high-dose group； the contents of acetic acid， propionic acid and butyric acid in the feces of the rats were determined. RESULTS Compared with the model group， the body weight after 7 and 14 days of medication， fecal water content， AWR threshold， and the protein expressions of 5-HT4R and SERT in colon tissue were increased significantly in the A. macrocephala-A. lappa medium-dose and high-dose groups （P＜0.05 or P＜0.01）； serum contents of 5-HT and SP， intestinal propulsion rate （except for A. macrocephala-A. lappa medium-dose group）， the protein expression of 5-HT3R in colon tissue were decreased significantly （P＜0.01）； diarrhea relief， mental state recovery， and partially recovery of the structure of colon tissue were all found； moreover， the diversity and species number of gut microbiota were reduced in A. macrocephala-A. lappa high-dose group and the content of butyric acid in fecal samples was significantly reduced （P＜0.05）. CONCLUSIONS The compatibility of A. macrocephala and A. lappa can improve intestinal motility and sensitivity of IBS-D model rats with spleen deficiency， and alleviate diarrhea. This may be related to improving changes in intestinal microbiota structure， reducing 5-HT expression and butyric acid content， and increasing 5-HT4R and SERT expression.

Objective: To investigate the role of long non-coding RNA double homeobox A pseudogene 9 (DUXAP9) in head and neck squamous cell carcinoma (HNSCC) and to evaluate the expression level, molecular function and mechanism of DUXAP9 in HNSCC cells. Methods: Differential expression of lncRNAs between normal and tumor tissues in HNSCC tissues were screened using lncRNA microarray, the expression level of DUXAP9 in HNSCC tissues and its relationship with prognosis were analyzed in the TCGA database. The expression levels of DUXAP9 in HNSCC tissues and cell lines were detected using qRT-PCR. The function in HNSCC cells after DUXAP9 silencing was evaluated using the CCK-8 assay, wound healing assay, Transwell migration assay and subcutaneous xenograft assay in nude mice. Changes in the transcription and translation of epithelial-mesenchymal transition (EMT)-related proteins in head and neck squamous cell carcinoma cells after DUXAP9 silencing were detected using qRT-PCR and Western blot. Results: lncRNA microarray results showed that, compared to adjacent normal tissues, DUXAP9 was abnormally upregulated in HNSCC tissues. Analysis from TCGA database showed that, compared to HNSCC patients with low DUXAP9 expression, HNSCC patients with high DUXAP9 expression had poorer survival. The relative expression of DUXAP9 in HNSCC tissues and 4 HNSCC cell lines increased compared to paired adjacent normal tissues as detected using qRT-PCR. Silencing DUXAP9 significantly inhibited the proliferation, migration and expression of EMT-related genes in HNSCC cells. The silencing of DUXAP9 significantly inhibited subcutaneous tumorigenesis of the HNSCC cell line CAL27 in nude mice. Conclusion Silencing DUXAP9 significantly inhibited the proliferation of HNSCC cells and subcutaneous xenografts in nude mice. DUXAP9 may mediate the migration of head and neck squamous cell carcinoma cells via the EMT pathway.

This study aimed to obtain the first national estimate of the prevalence of autism spectrum disorder (ASD) in Chinese children. We targeted the population of 6 to 12-year-old children for this prevalence study by multistage convenient cluster sampling. The Modified Chinese Autism Spectrum Rating Scale was used for the screening process. Of the target population of 142,086 children, 88.5% (n = 125,806) participated in the study. A total of 363 children were confirmed as having ASD. The observed ASD prevalence rate was 0.29% (95% CI: 0.26%-0.32%) for the overall population. After adjustment for response rates, the estimated number of ASD cases was 867 in the target population sample, thereby achieving an estimated prevalence of 0.70% (95% CI: 0.64%-0.74%). The prevalence was significantly higher in boys than in girls (0.95%; 95% CI: 0.87%-1.02% versus 0.30%; 95% CI: 0.26%-0.34%; P < 0.001). Of the 363 confirmed ASD cases, 43.3% were newly diagnosed, and most of those (90.4%) were attending regular schools, and 68.8% of the children with ASD had at least one neuropsychiatric comorbidity. Our findings provide reliable data on the estimated ASD prevalence and comorbidities in Chinese children.
