OBJECTIVETo assess the feasibility of chromosomal microarray analysis(CMA) for studying the correlation between birth defects and chromosomal aberrations.

METHODSA total of 2000 patients with birth defects were recruited for the CMA testing.

RESULTSFive hundred twenty two patients (26.1%) were found to have chromosomal abnormalities. These included 24 cases with numerical abnormalities, 11 with mosaicisms, and 11 with uniparental disomies. The remaining 476 cases were of well-known microdeletion or microduplication syndromes. The advantage of CMA over conventional karyotyping was demonstrated in many cases.

CONCLUSIONAs a powerful tool for patients with birth defects, CMA can produce a higher diagnostic yield compared with conventional karyotyping.

Objective To further determine their possible synergistic effect on accelerating wound healing, adenovirus vector containing recombinant human hPDGF-A and hBD2 genes was constructed and the expression of exogenous genes in transformed mesenchymal stem cells derived from rat bone marrow was observed. Methods By putting IRES in the middle of hPDGF-A and hBD2, these two genes were expected to be expressed individually. The shuttle vector was named as pAdTrack-hPDGF-A-IRES2-hBD2, which homologously recombinated with Adeasy-1 in BJ5183 cells and formed the mammalian expression vector pAdeasy-hPDGF-A-IRES2-hBD2. Furthermore, the recombinant vector was packaged in 293 cells into infectious recombinant adenovirus, which were used to infect BMSCs. The expression of hPDGF-A and hBD2 in BMSCs was detected by RT-PCR. Results We successfully constructed recombinant adenovirus vector that simultaneously expressed hPDGF-A and hBD2. The expressions of hPDGF-A and hBD2 were confirmed by RT-PCR on transformed BMSCs. Conclusion The established BMSCs that overexpressed hPDGF-A and hBD2 provide a new strategy of combining cell therapy and gene therapy to promote wound healing, especially the chronic one.

Objective: To establish an autoregressive moving average model for the prediction of tuberculosis cases in students of Shanxi Province, and to provide scientific basic for the prevention and treatment of pulmonary tuerculosis among students. Methods: A optimized ARIMA model was set up based on reported monthly data of TB in students from January 2010 to September 2019 in Shanxi Province by SAS 9.3 software, and the incidence trend in the next two years was predicted. Results: The average reported rate of active TB in students of Shanxi Province was 23.52 per 100 000 from 2010 to 2019,showing an overall downward trend(χ2=999 980.46，P<0.01). The optimal model was SARIMA(0，1，1)(0，1，1)12,SBC=982.16. The fitted equation was (1-0.63B) (1-B12)Yt=(1-0.61B12)εt. The mean relative error was 19.35%,and the predicted incidence trend was consistent with the previous years,and the peak was from March to May. Conclusion Substantial progress has been made in student TB prevention of Shanxi Province. The ARIMA product season model is suitable for forecasting the TB incidence in students,so as to provide scientific guidance for its early prevention and control.

Objective To explore the safety and feasibility of guiding catheter passing through spasmodic vessels in patients undergoing percutaneous coronary intervention (PCI) via radial artery access by the aid of PCI guiding wire and balloon .Methods The clinical data of 33 coronary artery disease (CAD) patients undergoing PCI via radial artery access with radial artery or (and) brachial artery spasm ( group A ) were retrospectively analyzed .Among all these patients , guiding catheters were delivered through the spasmodic vessels successfully by the aid of PCI guiding wires and balloons .The clinical data of other 38 CAD patients having PCI during the same period performed by other operators via radial artery or ( and ) brachial artery approach and experienced vessel spasm were anlysed as the control ( group B ) .All patients in group B received conventional anti-spasm management during PCI .All vessel spasm was identified by angiography.For patients in group A , a diameter of 0.014 inch guiding wire was chosen to pass through the spasmodic vessel segment carefully and gently .The diameter of balloon should be chosen according to the diameter of guiding catheter .A balloon diameter of 2.0 mm and 2.5 mm was corresponded to 6F and 7F guiding catheter respectively .The balloon was advanced to the tip of guiding catheter , keeping a half in catheter and a half in vessel followed by inflating the balloon with a pressure of 8 atm.The balloon was kept inflated the guiding catheter was pushed in vitro carefully and slowly until the catheter passed through the spasmodic vessel segment .Then the balloon was deflated and pulled out together with PCI guiding wire . Exchanged a diameter of 0.035 inch wire and completed the positioning of guiding catheter .After finishing the PCI, radial or ( and) brachial angiography was performed again to observe if spasm disappeared and to determine if there any contrast medium exudation .For patients in group B , routine approach was applied including administration of nitroglycerine , diltiazem or nitroprusside etc . to relieve vessel spasm. Results The location of vessel spasm was similar in group A and group B ( P=0.150 ) , and the incidence rate of spasm in brachial artery was higher than that in radial artery in both groups .The chance of guiding catheter crossing the spasmodic vessel segment was significantly higher in group A than in group B ( 100%vs.39.5%, P=0.00).In patients whose guiding catheter could pass through the spasmodic vessel segment successfully , time spent in group A was shorter than in group B ( P=0.000 ) .The patient number which time spent was less than five minutes , five to 15 minutes and more than 15 minutes was 30 and 2 ( 90.1%vs.13.3%) , 3 and 7 ( 9.9% vs.46.7%) and 0 and 6 ( 0% vs.40.0%) in group A and in group B respectively.The incidence of forearm hematoma was lower in group A than in group B without statistical difference [6.1%(2/33) vs.18.4%(7/38), P =0.113].Conclusions It is safe and feasible for passing guiding catheter through spasmodic vessels during PCI via radial artery access by the aid of PCI guiding wire and balloon .

OBJECTIVE: To investigate the status of subjective well-being (SWB) for medical staffs who contact with patients directly in a tertiary hospital.
 METHODS: Staffs from a tertiary hospital in Hunan province were investigated the SWB Scale (SWBS-cc20) from 2012 to 2014.
 RESULTS: The scores of SWB for medical staffs are high (81.67±12.33). Among the 10 sub-dimensions of SWB, medical staffs performed the best in family atmosphere, personal growth, and interpersonal adaptation, while performed the worst in physical health, mental health and material contentment. Title, job nature, education and occupation significantly affected the status of SWB. Staffs who directly connected with patients have less scores of SWB than those who do not (t=-4.80, P<0.001). Moreover, they perform better in contentment (OR=0.079, 95% CI 1.278 to 2.214, P<0.001), but worse in mental health (OR=1.315, 95% CI 1.023 to 1.690, P<0.05) and physical health (OR=1.313, 95% CI 1.029 to 1.677, P<0.05).
 CONCLUSION Medical staffs have high scores of SWB. Staffs who directly connected with patients have less scores of SWB than those who do not. Moreover, they perform better in contentment, but worse in mental health and physical health.
