OBJECTIVETo study the effective factors and difficulties in the application of Suitable Technique of Chinese Medicine(STCM) in the countryside.

METHODSA survey on current situation was carried out on incumbency doctors in 12 cities with a self-designed questionnaire.

RESULTSIn 1387 available questionnaire, 51.8% of the doctors agreed with the active application of some STCM in the countryside while 42.8% thought that they could be promoted. Factors as age,titles of professional, jobs and holding a diploma had close relation with their attitude to the application of techniques in their cities (P < 0.01).

CONCLUSIONSuitable technique of CM could be adopted by the rural doctors working at the grassroot healthcare unit, suggesting that these techniques should be popularized step by step.

Objective To investigate the role of triggering receptor expressed on myeloid cells 1 (TREM1)in rats with neuropathic pain and its possible mechanism.Methods Forty-eight male a-dult Sprague-Dawley rats,weighing 220-300 g,were successfully placed intrathecal catheters,and then randomly divided into 4 groups (n=1 2 ):sham operation group (group S),neuropathic pain group (group CCI),TREM1 shRNA group (group RNAi)and negative lentivirus group (group Vi-rus).The neuropathic pain was induced by chronic sciatic nerve compression injury (CCI).In group RNAi,30 μl pGLVU6/RFP/Puro-shRNA (1×109IU/ml)was injected intrathecally 1 week before modeling.Group Virus was injected with 30 μl negative lentivirus,whereas group CCI and group S with equal amount of normal saline.MWT and TWL were measured 1 day before (baseline)and 1,3, 7,14 day after modeling.When behavioral test finished,the expression levels of TREM1,TLR4, MyD88,IκBαand p-NF-κB p65 in spinal cord were determined by Western blot.Whereas the mRNA expression levels of IL-1β,TNF-αand IL-6 in spinal cord were measured by RT-PCR.Results Com-pared with group S,the expression levels of TREM1 in groups CCI and Virus significantly increased (P<0.05).While compared with group CCI,the TREM1 expression of group RNAi in spinal cord significantly decreased (P<0.05).Compared with group S,MWT and TWL of groups CCI,Virus and RNAi after modeling and the expression of IκBαsignificantly decreased (P<0.05),whereas the expression of TLR4,MyD88,p-NF-κB p65 increased significantly (P<0.05),as well as the expres-sion of IL-1β,TNFαand IL-6 mRNA (P<0.05).Compared with group CCI,the MWT and TWL of group RNAi after modeling and the expression of IκBαremarkably increased (P<0.05),whereas the expression of TLR4,MyD88 and p-NF-κB p65 in the spinal cord remarkably decreased (P<0.05), as well as the expression of IL-1β,TNF-αand IL-6 mRNA (P<0.05).Conclusion TREM1 knock-down can alleviate neuropathic pain,the underlying mechanism might be the inhibition of TLR4/MyD88/NF-κB signaling pathway.

Objective To investigate the effects of propofol combined with nalbuphine on diaphragmatic movement monitored by ultrasound in patients undergoing colonoscopy.Methods Forty patients, males 21 and females 19, aged 18-65 years, BMI 18-25 kg/m2, ASA physical status I or II, were recruited and scheduled to undergo elective painless colonoscopy.All patients were randomly divided into two groups (n =20):propofol group (group P) and propofol combined with nalbuphine group (group F).Patients in group F received nalbuphine 0.1 mg/kg intravenously 1 min before propofol administration, and patients in group P received same volume of normal saline.Propofol was infused by TCI and the initial target plasma concentration was set at 2μg/ml in all patients.The target concentration was adjusted gradually until the Ramsay sedation score reached 5.Then colonoscopy was started.During the colonoscopy, the propofol concentration was adjusted according to the Ramsay score.Ultrasound was used to monitor the movement of the right diaphragm of the patients.SpO2, MAP, HR, PETCO2, RR, diaphragmatic movement (DM), diaphragmatic thickness at the end of inspiration (TEI) and diaphragmatic thickness at the end of expiration (TEE) were recorded under calm breathing after entering the room (T0), Ramsay sedation score 5 points after propofol administration (T1), and Ramsay sedation score 2 after endoscopy (T2).The diaphragmatic thickening fraction (DTF) was calculated:DTF= (TEI-TEE) /TEI.Adverse reactions such as bradycardia, hypotension, body movement, and respiratory depression were recorded.Results Compared with T0, MAP, SpO2, HR and RR decreased, and PETCO2 increased at T1 time point in patients of the two groups (P<0.05).Compared with group F, the dose of propofol increased in group P (P<0.05).DM at T1 and T2, DTF at T1 were obviously higher in group F than those in group P (P<0.05).There were two cases had body movement in group P, and one case had bradycardia in group F.There was no case suffered from hypotension, respiratory depression and reflux aspiration in two groups.Conclusion Compared with propofol alone, propofol combined with nalbuphine can attenuate the dysfunction of the diaphragm.

AIM: To investigate whether oxytocin has neuroprotective effects on hippocampal CA 1 pyramidal neurons from neonatal rats exposed to hypoxic-ischemic brain injury and the underlying mechanisms.METHODS:An in vitro model of hypoxic-ischemic injury was used by exposing the brain slices to oxygen-glucose deprivation(OGD)solution. Acute dissociated brain slices(6~8 slices per rat)from 8 Sprague-Dawely rats of 7~10 d old were used.The slices were randomly divided into 4 groups: control group, OGD 20 min group, OGD 40 min group and OGD +oxytocin group.The effect of oxytocin on neuronal death was evaluated by TO-PRO-3 staining.Fresh brain slices from other 20 neonatal rats were divided into OGD group,OGD+oxytocin group,OGD+dVOT(oxytocin receptor antagonist)+oxytocin group,and OGD+bicucuclline(GABAAreceptor antagonist)+oxytocin group.The onset of anoxic depolarization in the hippocampal neurons treated with different drugs was recorded by whole-cell patch-clamp techniques.RESULTS: The results of TO-PRO-3 staining showed that neuronal deaths in hippocampal CA 1 area were increased over the prolonged OGD time.Oxyto-cin significantly reduced the hypoxic-ischemic deaths.Oxytocin dramatically prolonged the onset time of anoxic depolariza-tion after the application of OGD solution.Both dVOT and bicuculline blocked this effect.CONCLUSION: Oxytocin plays a neuroprotective role in neonatal rat hippocampal CA 1 pyramidal neurons by enhancing the inhibitory synaptic trans-mission via oxytocin receptors.Therefore,oxytocin is useful as a candidate for neuroprotective treatment after neonatal hy -poxic-ischemic brain injury.

Objective To investigate the temporal and spatial distribution characteristics of non-syndromic cleft lip with or without palate (NSCLP) who born in Gansu Province from 2010 to 2016, and to establish a predictive model for developing the strategies for the prevention and control of NSCLP. Methods Spatial epidemiological research method and geographical information systems (GIS) were used to conduct thematic mapping, spatial correlation analysis, high/low clustering analysis, hotspot analysis and Kirging interpolation prediction for NSCLP patients in Gansu Province from 2010 to 2016. Results From 2010 to 2016, the aggregation trend of NSCLP incidence in 89 counties in Gansu Province was different obviously, the southeast area was high and the northwest was low. Based on the data of the cumulative incidence of NSCLP from 2010 to 2016 in Gansu, the spatial distribution of NSCLP presented positive spatial correlation (Moran’I=0.274，Z=7.814，P<0.001) and the aggregation type was high-high cluster(Getis Gi=0.000 003，Z=4.381，P<0.001), with 22 hot spots. The Kirging interpolation prediction results showed that the main prevalence trend of NSCLP in Gansu extended from Longdong to Longxi and Longnan areas. Conclusions The geographical distribution of NSCLP had a positive spatial correlation and a high-high aggregation type in Gansu from 2010 to 2016. The high aggregation area is concentrated in Longdong, Longxi and Longnan of Gansu, which suggest that it is essential to focus on prevention and control in these areas.

Objective To investigate the clinical distribution and antimicrobial resistance of carbapenem-resistant Enterobacteriaceae (CRE) in Dongguan.Methods CRE isolated from hospitalized patients in 22 secondary and above medical institutions which participated in bacterial monitoring in Dongguan between January 2015 and June 2016 were retrospectively analyzed,antimicrobial resistance was analyzed by WHONET 5.6 software.Results A total of 71 CRE isolates were detected,with a isolation rate of 0.34％ (71/20 713).53 strains(74.65％) of CRE were isolated from patients aged 15-60 years old;46 (64.79 ％) were from male patients;CRE were mainly isolated from patients in intensive care unit(36 strains,50.70 ％);the main specimen was sputum(34 strains,47.89 ％),followed by urine (11 strians,15.49 ％) and wound secretion(6 strains,8.45 ％);the main infection type was healthcare associated infection (64 strains,90.14 ％);CRE were mainly distributed in tertiary hospitals(56 strains,78.87 ％),the isolation rate of CRE in tertiary and secondary hospitals were 0.41 ％(56/13 677)and 0.21％(15/7 036) respectively.71 strains of CRE were all resistant to imipenem,resistance rate to meropenem was 81.12％,only amikacin and tobramycin had drug resistance rates of ＜40％ (21.38％ and 38.79％ respectively),resistance rate to trime thoprim/sulfamethoxazole was 48.23 ％,while resistance rates to fluoroquinolones,third-generation cephalosporins,and enzyme inhibitors were all＞60.Conclusion The isolation rate of CRE in Dongguan is lower than that of the whole nation and the other provinces,effective prevention and control measures should be taken according to the key population and departments that isolated CRE,antimicrobial use should be rational.

To reveal the variation of polysaccharides and alcohol-soluble extractives of rhizomes Polygonatum cyrtonema from different producing areas,growing years,and harvesting seasons,25 wild samples from the main producing areas( provenances) of China and 6 artificial cultivated samples were collected and detected. The 6-year-old rhizomes of the artificial cultivation were gathered from Qingyuan,Zhejiang every 2 months during 2016 to 2017. Anthrone-sulfuric acid method and hot-dip method were used to determine the contents of polysaccharides and alcohol-soluble extractives respectively. The results showed that provenances,age sections and harvesting seasons affected the quality of Polygonati Rhizoma significantly. The content of polysaccharides from different provenances varied from 6. 96% to 20. 09%,and the content of extractives varied from 32. 08% to 78. 99%. The polysaccharides and extractives' content were the highest at 2-year-age sections,active constituents accumulation peaked in the third year,then decreased significantly with age increasing. The contents of polysaccharides and extractives accumulated were highest when aerial parts,up to 15. 39% and 78. 99% respectively. In summary,the activity and consistency fluctuated with producing areas. while such phenomenon indicated a huge potential of breeding. Additionally,the results showed that collecting Polygonati Rhizoma in February or August as herbal textual recorded were unreasonable,neither in spring or autumn according to the Chinese Pharmacopoeia( 2015 edition). Because these collecting periods didn't have the highest contents of polysaccharides and extractives. Therefore,based on phenological options,the rhizomes of P. cyrtonema should be harvested when the aboveground parts had just withered.
