OBJECTIVE To explore the mechanism of Yishen tongluo formula （YSTLF） in improving abnormal lipid metabolism based on the sterol regulatory element binding proteins （SREBPs） pathway. METHODS Using C57BLKS/J （db/db） mice as model and C57BLKS/J （db/m） mice as normal control， the mechanism of 1， 2.5 and 5 g/kg YSTLF improving abnormal lipid metabolism of db/db mice was investigated by determining the liver coefficient， the contents of serum total cholesterol （TC）， triglyceride （TG）， low-density lipoprotein （LDL） and high-density lipoprotein （HDL）， observing steatosis and lipid accumulation in liver tissue of mice， detecting the protein expressions of SREBP-1 and SREBP-2 as well as mRNA transcription levels of Srebp- 1c， Srebp-2 and their downstream lipid metabolism-related target genes （Fasn， Acc1， Scd5， Fads1， Hmgcr， Dhcr24， Insig-1， Fdps） in liver tissue of mice. Using low-fat cultured human liver cancer cell HepG2 as an in vitro cell model for abnormal lipid metabolism， and 25-HC （SREBPs inhibitor， 10 μmol/L） as the control， the effects of 125， 250 and 500 μg/mL YSTLF on protein expressions of SREBP-1 and SREBP-2 as well as mRNA transcription of SREBP-1c， SREBP-2 and their downstream lipid metabolism-related target genes were investigated to verify the mechanism in vitro. RESULTS 1， 2.5， 5 g/kg YSTLF significantly reduced the levels of TC， TG and LDL， the percentage of lipid droplet-positive region in liver tissue and liver coefficient， significantly down-regulated protein expressions of Pre-SREBP-1， n-SREBP-1， Pre-SREBP-2 and n-SREBP-2， and mRNA transcription of Srebp-1c， Srebp-2 and their downstream target genes in liver tissue， while significantly increased HDL level， with statistical significance （P＜0.05 or P＜0.01）. In the cell experiment in vitro， the expressions of the above-mentioned proteins and genes in the cells treated with YSTLF at 125， 250 and 500 μg/mL for 24 hours were consistent with those in the animal experiment； there was no significant difference in the expressions of the above-mentioned proteins and genes between inhibitor control group and 250， 500 μg/mL YSTLF groups （P＞0.05）. CONCLUSIONS YSTLF can regulate the expression of transcription factor SREBPs， so as to inhibit the high expression of fatty acid and cholesterol synthesis-related genes， promote the degradation of TC and TG， improve the abnormality of lipid metabolism and inhibit lipid accumulation， thus playing the role of lipid-lowering.

The patient was a 62-year-old female with acute onset who was diagnosed with transient ischemic attack. This article aims to improve the knowledge of NIID with stroke-like onset by this case presentation and avoid misdiagnosis.

Objective:To analyze the influenza vaccination status of chronic disease management patients in Qingpu district of Shanghai and the vaccination characteristics of different characteristic populations, so as to provide scientific basis for improving the influenza vaccination rate of chronic disease patients in the community.Methods:By comparing the data of Shanghai chronic disease management information system, immunization planning information system and medical association platform, 89 453 subjects who met the inclusion and exclusion criteria in Qingpu district were selected as the research objects. The vaccination coverage rate of the study subjects was calculated according to gender, age group, urban and rural distribution, occupation, chronic disease type and quantity, and the vaccination coverage rate of different subgroups was compared to analyze the influencing factors of vaccination coverage rate.Results:Most of the 89 453 patients with chronic diseases were 60 years old and above (71.93%). Patients with hypertension, diabetes, chronic obstructive pulmoriary disease (COPD) and three chronic diseases accounted for 87.12%, 28.67%, 8.71% and 1.83%, respectively. Influenza vaccination coverage in the 2016/2017 flu season was low, at 0.32%. Influenza vaccination coverage rate of women (0.37%) was higher than that of men (0.27%), which was 1.41 times respectively(95% CI: 1.16, 1.72) that of men patients. The coverage rate of influenza vaccination for the 70-79 year-old group was the highest (0.74%), which was 1.74 times respectively(95% CI: 1.39, 2.19) that of 60-69 year-old patients. The vaccination coverage rate of government departments and institutions was the highest (1.14%), which was 12.58 times respectively(95% CI: 4.52, 34.99) that of retirees. The vaccination rate of COPD patients (3.68%) was 2.50 times (95% CI: 1.66, 3.77) higher than that of patients without COPD.Conclusions:Influenza vaccination rate for chronic disease management patients in Qingpu district of Shanghai is low. Gender, occupation, age and types of chronic diseases are the influencing factors. Patients with chronic disease management should be included in the priority vaccination targets for influenza vaccines, and vaccination intervention for occupational chronic diseases such as non-retired agriculture and forestry patients, especially male patients, should be strengthened to improve influenza vaccination coverage rate.

Objectives:To explore the GAA varient spectrum and the genotype-phenotype correlations in patients with glycogen storage disease type Ⅱ (Pompe disease, PD), as well as to estimate the disease incidence based on carrier rate of GAA varients in Guangzhou population.Methods:A total of 57 PD cases were retrospectively enrolled at Guangzhou Women and Children′s Medical Center from January 1, 2010 to May 31, 2020. All patients presented symptoms before the age of 18 years. Each diagnosis was further confirmed by GAA enzyme activity and GAA variants. The carrier rate of GAA varients was calculated based on variants detected by whole exon sequencing among 2 395 healthy children in Guangzhou.Results:Among the 57 PD patients (including male 26, female 31),twenty-eight patients with infantile onset PD (IOPD) presented with progressive general muscle weakness and cardiomyopathy. The mean ages of symptom onset and diagnosis were (2.5±1.4) and (5.0±3.0) months, respectively. Twenty-six cases died in the first year after birth.Twenty-three patients with late onset PD (LOPD) presented with progressive muscle weakness. Seven of them had respiratory failure at diagnosis. The mean ages of symptom onset and diagnosis were (12.0±5.0) and (17.0±7.5) years, respectively. Six children with atypical IOPD showed motor delay, muscle weakness and cardiomyopathy. Their diagnosis was confirmed at 2.5-7.0 years of age. Among the 57 patients, 47 different variants were identified in the GAA gene. Three variants: c.797C>T, c.1109G>A and c.1757C>T were novel. c.1935C>A (25/114, 21.9%) and c.2238G>C (15/114, 13.2%) were the most common variants, detected in 57.1% of IOPD and 65.2% (15/23) of LOPD patients, respectively. Among the 28 IOPD patients, 26 cases (92.9%) carried at least one missense variant which indicated positive cross-reactive immunologic material (CRIM). The carrier rate of pathogenic variants in GAA gene among healthy children was 24/2 395. The estimated incidence of PD in this population is about 1/40 000. The frequencies of pseudodeficiency variants c.1726G>A and c.2065G>A homozygotes were 26.3% (15/57) and 35.1% (20/57) in PD patients, which were significantly higher than those (1.7% (40/2 395) and 3.9% (94/2 395)) in healthy children (χ2=151.2, 121.9; both P<0.01). Conclusions:PD presents as a spectrum, some as atypical IOPD. The c.1935C>A and c.2238G>C are common variants, correlated with IOPD and LOPD respectively. The c.796C>T and c.1082C>T are usually found in atypical IOPD. The majority of IOPD patients is predicted to be CRIM positive. The estimated incidence of PD is about 1/40 000.

The two curves of the fitted values and the measured values were close,suggesting that the model has good fitting ability. Conclusion Time series analysis and the seasonal ARMA model have good predictive ability in predicting HFMD.

Objective To identify a myeloid differentiation factor 88(MyD88)in Oncomelania hupensis,and characterize the role of MyD88 against Schistosoma japonicum infection. Methods The complete cDNA of MyD88 in O. hupensis was ob-tained by using rapid amplification of cDNA ends(RACE),and homologues sequences and conserved domains were aligned and the structure of MyD88 was predicted either. A phylogenetic tree of MyD88 was further constructed with other species. In ad-dition,the mRNA expression level of O. hupensis MyD88 before and after S. japonicum infection was investigated by real-time quantitative PCR(RT-qPCR). Results The cDNA of O. hupensis MyD88 consisted of 1406 bp open reading frame(ORF),en-coding 468 amino acid residues,which contained death domain and Toll/interlrukin-1 receptor(TIR)domain,the typical fea-tures of MyD88 family proteins. The predicted amino acid sequence of O. hupensis MyD88 shared 38%-52%identity with other mollusc. O. hupensis MyD88 was phylogenetically closeted to Biomphalaria glabrata MyD88. The O. hupensis MyD88 existed in all selected tissues and expressed highly in hemocyte,up-regulated after S. japonicum infection in all selected tissues except cephalopodium,especially higher in whole snail and hemocyte. Conclusion MyD88-dependent signaling pathway is present in O. hupensis and plays an important role in innate immune response against S. japonicum infection.

OBJECTIVE:To investigate the effects of Qigong pills decoction combined with chemical drugs on hormone levels of polycystic ovarian syndrome(PCOS)patients complicated with infertility. METHODS:A total of 98 PCOS patients complicated with infertility selected from gynaecology department of our hospital during Jul. 2015-Jun. 2016 were divided into observation group and control group according to random number table,with 49 cases in each group. Control group was given Clomiphene ci-trate tablet 50 mg orally,qd,for consecutive 5 d;B-ultrasonography for follicle development was monitored at the 11th day of menstruation,and then they were given Chorionic Gonadotropin for injection 2000 U intramuscularly,qod,if there was not domi-nant follicle >10 mm till the diameter of follicle reached 18 mm. Observation group was additionally given one dose of Qigong pills decoction,every day 400 mL after decocted with water,each 200 mL for morning and night,on the basis of control group. After 3 months of treatment,the levels of FSH,LH,PRL,E2,T,DHEA-S and SHBG,the endometrial thickness,the number of mature follicle and pregnancy rate were compared between 2 groups. RESULTS:Before treatment,there was no statistical signifi-cance in the levels of FSH,LH,PRL,E2,T,DHEA-S or SHBG between 2 groups(P>0.05). 3 months after treatment,the lev-els of PRL,T and DHEA-S in 2 groups were decreased and E2,SHBG were increased significantly;the levels of FSH,PRL,T and DHEA-S in observation group were significantly lower than control group,while the levels of E2 and SHBG were significantly higher than control group,with statistical significance (P<0.05). Endometrial thickness of observation group were significantly higher than that of control group;pregnancy rate (18.37%) was significantly higher than control group (4.08%),with statistical significance (P<0.05). CONCLUSIONS:Qigong pills decoction combined with chemical drugs can help to improve pregnancy rate and regulate serum hormone level in the treatment of PCOS complicated with infertility.
