Objective To analyze the association HLA DQ gene polymorphism to MG susceptibility.Methods HLA DQA1 and DQB1 were genetyped using PCR RFLP Results Comparing the frequency of HLA DQA1 alleles between MG patients with hyperplasia or MG males with disease onset less than 30 years and the healthy controls It was found that the frequency of DQA1*0301 was significantly increased Furthermore,in comparison with the frequency of HLA DQB1 alleles between MG patients (included subgroups)and the healthy controls,the frequency of DQB1*0303 was significantly increased,while the frequencies of DQB1*0601 and DQB1*0602 were significantly decreased And these differences were statistically significant. Conclusions HLA DQA1*0301 contributes to the genetic susceptibility of MG with hyperplasia and MG males with disease onset ≤30 years old DQB1*0303 was susceptible to MG DQB1*0601 and DQB1*0602 were protective genes

This paper aims to prepare polyanhydride-Pirarubicin dose long-acting sustained-release implants for the treatment of bladder cancer and for the prevention of postoperative recurrence of bladder cancer. Pirarubicin hydrochloride (THP) and polyanhydride, in accordance with a certain proportion, were fully mixed in the agate morta and dissolved in dichloromethane, and then were cast into a film within a mold put in the dryer set at 4 degrees C. Each tablet implanted contained 5.0 mg of THP. Polyanhydride-pirarubicin sustained-release was implanted into the bladder mucosa of the rabbits, and blood and urine samples were taken at different times after the operation. The THP drug concentrations in urine and blood were determined with high-performance liquid chromatography. The THP concentration in urine was significantly higher than the THP concentration in plasma. The drug concentration in urine reached (92.5 +/- 7.4) microg/L at 250 d time after the operation. Polyanhydride-pirarubicin implants possess long-acting sustained-release level dynamics in the body. It can maintain a stable long-term drug release and can be expected to last a year and can effectively prevent recurrence of bladder cancer. The present experiments proved that the implants with sustained-release drug treatment are expected to be useful in the clinical application in prevention of bladder cancer recurrence.

Objective To analyze the multi-component,multi-target and multi-pathway mechanism of peony leaf in the treatment of cervical cancer based on network pharmacology. Methods The possible active components and targets in peony leaf were screened and predicted by pharmacological database and analysis platform of traditional Chinese medicine system,and the related targets of cervical cancer diseases were ob-tained by searching Therapeutic Target Database and others. The potential targets for the disease regulation were screened according to the active components of peony leaves entering blood,then the key target names and the pathways involved in the treatment of peony leaf were selected according to the network topological characteristic parameters. Then,the enrichment analysis was carried out by using ClueGO software plug-in. Results There were 194 target sites for 11 blood entry components in peony leaves. Finally,171 signal pathways were ob-tained,and 21 key pathways related to cervical cancer were obtained after the wide pathway was excluded,such as estrogen signaling pathway,neurotrophin signaling pathway and so on. Conclusion Peony leaves may play a vital role in the treatment of cervical cancer by acting on inflammatory,metabolic,immunological,endocrine and cell cycle related protein targets and pathways.

Objective To observe the effects of Levo-tetrahydropalmatine(l-THP)on the expression,regression and relapse of conditioned place preference(CPP)in ketamine induced rats,and to detect the content of dopamine(DA)in the striatum(caudate putamen,CPu)of the rat brain at different time points.Methods Ketamine addiction rat model was established by CPP.The effects of l-THP on the expression,regression and relapse of ketamine induced rat CPP were investigated using CPP score as the index.The content of DA in CPu of rats was determined by ultra-performance liquid chromatography coupled to tandem mass spectrometry(UPLC-MS/MS)after ketamine administration and l-THP intervention at 30 min,60 min,90 min,120 min and 150 min.Results It indicated that 1-THP could decrease the expression of CPP in ketamine induced rats,promote the process of CPP resolution and inhibit the process of relapse.In addition,l-THP combined with ketamine administration significantly inhibited the ketamine-induced increase in DA content in the CPu of the rats.Conclusion The mechanism of l-THP inhibiting the reward effect of ketamine may be related to blocking DA receptors and reducing the release of DA neurotransmitters.l-THP has potential implications for the treatment of ketamine addiction.

OBJECTIVETo investigate whether or not the gamma-aminobutyric acid (GABA) receptor subtype A genes GABRA5 and GABRB3 are associated with childhood absence epilepsy (CAE).
METHODSTwo microsatellite DNA, GABRA5 and GABRB3, adjoining to chromosome 15q11.2-q12 were used as genetic markers. Both case-control study and transmission/disequilibrium test (TDT) as well as fluorescence-based semi-automated genotyping technique were used in 90 trios with CAE and 100 controls to conduct association analysis.
RESULTSThe allele frequencies of the 2 microsatellite DNA in Chinese normal population are in good agreement with Hardy-Weinberg equilibrium. The polymorphism information content of microsatellite DNA GABRA5 and GABRB3, are 0.80 and 0.66 respectively. The allele 2 frequency of microsatellite DNA GABRA5 and the allele 5 frequency of microsatellite DNA GABRB3 are significantly higher in CAE patients than those in normal controls(P<0.001).
CONCLUSIONBoth microsatellite DNA GABRA5 and GABRB3 are good genetic markers. The gamma-aminobutyric acid receptor subtype A genes GABRA5 and GABRB3 may be directly involved either in the etiology of CAE or in linkage disequilibrium with disease-predisposing sites.

Objective:To investigate the prognosis and risk factors for children diagnosed with all types of subaortic stenosis(SAS) who developed recurrent left ventricular outflow tract obstruction after surgical treatment.Methods:The study retrospectively included patients aged 0-18 years old who underwent open heart SAS surgery at Fuwai Hospital from 2016-2019. Children with hypertrophic obstructive cardiomyopathy were excluded. Detailed operative notes, medical records and ultrasound information, and follow-ups were extracted. Recurrent SAS was defined as left ventricular outflow tract gradient 30 mmHg(1 mmHg=0.133 kPa) 1 month after SAS surgical treatment.Results:A total of 137 children were included in this study. The medium age of children at the time of SAS surgery was 4.6 years old(3 months-17.8 years old). After a median follow-up of 4.36 years(3.2-5.7 years), a total of 30 patients developed recurrent LVOTO, with a recurrence rate of 21.9%, and 7(5.1%) underwent a second surgery. Compared to the non-recurrent group, children in the recurrent group were younger at the time of surgery( P=0.0443), had a smaller body surface area( P=0.0485), and a longer length of stay( P=0.0380). In Cox analysis, when only considering preoperative variables, the independent risk factor for LVOTO recurrence were a peak left ventricular outflow tract gradient higher than 50 mmHg( HR=5.25, P=0.001), a BSA less than 0.9( HR=2.5, P=0.023), and a length of SAS 5 mm( HR=2.29, P=0.050). When both preoperative and intraoperative variables were considered, preoperative peak left ventricular outflow tract gradient 50 mmHg( HR=4.91, P=0.002) and peeling from the aortic valve( HR=3.23, P=0.010) were independent risk factors for postoperative recurrence. Conclusion:Recurrent LVOTO after SAS surgical repair is common, and regular postoperative follow-up is crucial to evaluate whether a secondary intervention is required. Regular postoperative follow-up is needed for children at high risk.
