OBJECTIVETo observe the impacts of the acupoint catgut implantation on postpartum pain of uterine contraction with qi and blood deficiency.

METHODSOne hundred and ten primiparas of natural delivery differentiated as qi and blood deficiency pattern in TCM were selected as the subjects. They were randomized into an acupoint catgut implantation group (55 cases) and a routine nursing group (55 cases). In the acupoint catgut implantation group, the catgut was implanted in Zigong (EX-CA 1), Zusanli (ST 36), Sanyinjiao (SP 6), Pishu (BL 20) and Geshu (BL 17) in 6 h after delivery; additionally, the routine post-delivery nursing was adopted. In the routine nursing group, the routine post-delivery nursing was applied simply. Visual analogue scale (VAS) and the pain relief time of uterine contraction were compared in 24 h, 48 h, 72 h and 96 h after acupoint catgut implantation between the two groups.

RESULTSVAS Scores in 24 h, 48 h, 72 h and 96 h after acupoint catgut implantation in the acupoint catgut implantation group were lower apparently than those in the routine nursing group (3.31 +/- 0.39 vs 4.31 +/- 0.29, 1.86 +/- 0.29 vs 2.66 +/- 0.25, 0.89 +/- 0.21 vs 1.59 +/- 0.24, 0.35 +/- 0.10 vs 0.69 +/- 0.13, all P < 0.05). The pain relief was achieved in (72.06 +/- 6.83) h in the acupoint catgut implantation group and was (123.42 +/- 11.12) h in the routine nursing group. The pain relief in the acupoint catgut implantation group was achieved more quickly (P < 0.01).

CONCLUSIONThe intervention of acupoint catgut implantation in 6 h after natural delivery in primiparas prevents effectively postpartum pain of uterine contraction.

AIM:To investigate the safety and effect of femtosecond laser-assisted cataract surgery with Cionni modified capsular tension ring (MCTR) implantation in the management of traumatic lens subluxation.METHODS: Totally 11 patients (11 eyes) with traumatic lens subluxation were divided into three groups according to the severity of lens dislocation, ranging from 90° to 120° (4 eyes), 120° to 180° (5 eyes) and 180° to 270° (2 eyes).The contact LenSx femtosecond laser cataract surgery platform was applied to create the capsulotomy, prepare nuclear fragmentation and make corneal wound creation.Anterior vitrectomy was performed in some patients during the surgery.After capsular retractors insertion and phacoemulsification, the MCTR was inserted to the capsular bag and fixed to the sclera.Finally, the IOL was implanted into the capsular bag.Postoperative visual acuity, intra-and post-operative complications, anterior capsular opening, IOL and MCTR position and intraocular pressure (IOP) were assessed.RESULTS:The duration of follow-up was 2mo.All the operations were completed successfully.Five eyes underwent cataract surgery combined with anterior vitrectomy.Four eyes had been inserted with 2-eyelet MCTR and seven eyes with 1-eyelet MCTR.The best corrected visual acuity (BCVA) after operation was better than 0.5 in 4 eyes, between 0.3 and 0.5 in 3 eyes, between 0.1 and 0.3 in 3 eyes, and less than 0.1 in 1 eye.Compared with preoperative BCVA, the difference was statistically significant (P<0.05).All the IOLs were stably centered and the eyelet of MCTR was fixated steadily between the iris and the anterior capsule.The common intra-and post-operative complications were subconjunctival hemorrhage, incomplete capsulotomy, residual cortex, secondary glaucoma and posterior capsular opacification.CONCLUSION:Femtosecond laser-assisted cataract surgery can improve the success rate of capsulorhexis, and reduce the difficulty of nuclear fragmentation.Femtosecond laser-assisted cataract surgery combined with MCTR implantation is an ideal surgical method for traumatic lens subluxation.

To perform a systemic review and meta-analysis of the diagnostic accuracy of PET (CT) and metaiodobenzylguanidine (MIBG) for diagnosing neuroblastoma (NB),electronic databases were searched as well as relevant references and conference proceedings.The diagnostic accuracy of MIBG and PET (CT) was calculated for NB,primary NB,and relapse/metastasis of NB based on their sensitivity,specificity,and area under the summary receiver operating characteristic curve (AUSROC) in terms of per-lesion and per-patient data.A total of 40 eligible studies comprising 1134 patients with 939 NB lesions were considered for the meta-analysis.For the staging of NB,the per-lesion AUSROC value of MIBG was lower than that of PET (CT) [0.8064±0.0414 vs.0.9366±0.0166 (P＜0.05)].The per-patient AUSROC value of MIBG and PET (CT) for the diagnosis of NB was 0.8771±0.0230 and 0.6851±0.2111,respectively.The summary sensitivity for MIBG and PET (CT) was 0.79 and 0.89,respectively.The summary specificity for MIBG and PET (CT) was 0.84 and 0.71,respectively.PET (CT) showed higher per-lesion accuracy than MIBG and might be the preferred modality for the staging of NB.On the other hand,MIBG has a comparable diagnosing performance with PET (CT) in per-patient analysis but shows a better specificity.

Objective To assess the association between air temperature and emergency room visits among patients covered by medical care program from ' third-grade' hospitals in Shanghai.Methods Generalized additive model (GAM) was used to analyze time series,and AR(P) was used to deal with auto correlation of time series.After controlling factors as both medium-term and long-term trends,day of the week,vocation,typical pneumonia and pollutants,the association between air temperature and emergency room visits in virtue of quadratic curve and differential coefficient principle were estimated.Results When air temperature was below 14.71℃,the increase of 95% confidence interval to relative risk in corresponding emergency room visits along with 1℃ increase of air temperature,was less than 1.However,when air temperature was above 19.59℃,the relative risk' s 95% confidence interval was greater than 1.When air temperature varied at the range of 14.71℃-19.59℃,the 95% confidence interval of the relative risk would include 1.Hence,air temperature range between 14.71℃-19.59℃,was called the optimum temperature range.Conclusion Our findings indicated that the current air temperature had an acute impact on the number of emergency room visits among patients covered by medical care program visiting those third grade hospitals in Shanghai.

Objective To evaluate the role of cerebral state index(CSI),burst suppression (BS)and electromyograph(EMG)in monitoring coma/consciousness depth and damage degree of brain. Methods CSM was done in 50 cases with brain injury and coma to analyze its relation with physical reflection,auditory evoked potential(AEP),Glasgow coma score(GCS)and Glasgow outcome scale (GOS).Results As scale range meaning from consciousness to deep coma and to brain death,CSI 0- 100 was positively correlated with coma depth,coma score of GCS and physical reflection.CSI changes under invariable ache stimulation in combination with BS and EMG can accurately estimate prognosis and quantify changes of brain function.Conclusions The quantifiable digit of coma/consciousness depth and damage degree in brain function by CSM can attain real time judgment of dynamic evolvement course of coma and objective guide clinical therapy and assure prognosis,as will change absolutely scoring coma/ consciousness depth and prognosis under current state of artificial diversity and lacking objective evi- dences.

OBJECTIVETo establish chemiluminescence enzyme immunoassay (CLEIA) for quantitative detection of procollagen III N-terminal peptide (P III NP) in serum.

METHODSA sandwich reaction was preformed with horseradish peroxidase labeled monoclonal antibody of P III NP as the catalytic enzyme and the luminol as the luminescence reagent. Several reactions liquid's concentration and reaction conditions were optimized. The method was evaluated in all aspects such as linear range, sensitivity, specificity, stability and so on. The CLEIA was compared with imported ELISA kits, by detecting clinical serum.

RESULTSThe linear range was 0.8-85 ng/ml. The detection limit was 0.5 ng/ml. Inter-assay and intra-assay RSD were both less than 10%. The recoveries of three different spiked concentration samples were 96.2%, 91.2% and 101.1%. After stored at 4 degrees C and 37 degrees C for 3, 5, 7 days, the analysis showed correlation coefficient higher than 0.99 and RSD lower than 6%. The detected results of clinical sera with CLEIA closely corresponded to those with imported ELISA.

CONCLUSIONEstablished CLEIA for quantity determination of serum P III NP has high accuracy, sensitivity and repeatability.

OBJECTIVETo study the changes of microRNA expression in cortex tissues in neonatal rats with hypoxic-ischemic brain damage (HIBD)and the possible roles of microRNA in the pathogenesis of HIBD. METHODS Rat HIBD model was prepared. The cortex tissues were obtained 14 days after the HIBD event. The microRNA expression profiles were measured using microRNA microarray. Expression of 9 microRNAs (miR-126,-26a,-674-5p,-21,-25,-290, miR-124,-125b-5p and microRNA-9a) was determined by quantitative real-time PCR.

RESULTShe results of microRNA expression profiles indicated that 27 pieces of microRNA were up-regulated more than 2 folds and 60 pieces were down-regulated more than 2 folds compared with the normal control group. The results of the 9 microRNAs detected by quantitative real-time PCR were consistent with those detected by microRNA microarray.

CONCLUSIONSHIBD rats have significant changes in microRNA expression, suggesting that microRNA expression may play important roles in the pathogenesis of HIBD.

OBJECTIVETo analyze the differential proteomics in human umbilical cord mesenchymal stem cells (MSC) induced by chemical hypoxia-mimetic agent cobalt chloride (CoCl(2)) by two-dimensional gel electrophoresis (2-DE) and mass-spectrometry.

METHODS2-DE was performed to separate proteins from treated and untreated human umbilical cord MSC with CoCl(2). 2-DE images were analyzed by ImageMaster 2D Platinum software 6.0. The differential expressed proteins was identified by MALDI-TOF-MS. The differential proteins were classified based on their functions.

RESULTS2-DE reference patterns of CoCl(2) treated human umbilical cord MSC were established. A total of twenty-six differential proteins were identified, of them eleven proteins were up-regulated and fifteen down-regulated. Their biological functions involved in carbohydrate metabolism, protein metabolism and modification, lipid metabolism, coenzyme and prosthetic group metabolism, cell cycle, immunity and defense, cell structure and motility, signal transduction, protein targeting and localization, neuronal activities, muscle contraction, etc. Peroxiredoxin1 (Prdx) was down-regulated, whereas alpha-enolase (ENO1) and vesicle amine transport protein 1 homolog (VAT1) up-regulated.

CONCLUSIONThe effects of hypoxia on human umbilical cord MSC were participated by multiple proteins and involved in multiple functional pathways.

OBJECTIVETo study the effects of Down syndrome cellular adhesion molecule (DSCAM) on differentiation of rat marrow mesenchymal stem cells (MSCs) into neurons in vitro.

METHODSMSCs from Sprague-Dawley rats were induced into neurons by baicalin. The expression of DSCAM before and after induction was evaluated by immunocytochemical staining and Western blot assay. After knockdown of DSCAM by siRNA transfection, the differentiation rate of neurons derived from MSCs was measured.

RESULTSBefore induction, the expression of DSCAM was not detectable in MSCs. After bFGF preinduction for 24 hrs, DSCAM was slightly expressed in MSCs (1.71+/- 0.67%). The DSCAM expression increased 6 hrs after baicalin induction (15.79+/- 4.24%), reached a peak at 3 days (53.16+/- 5.94%) and then decreased gradually. The DSCAM expression 6 days after baicalin induction (28.99+/- 6.72%) was significantly lower than that at 3 days (P<0.01). However, after DSCAM-siRNA transfection, the DSCAM expression in MSCs was significantly reduced. MSCs did not express neuron-specific beta-III-tubulin before induction. After baicalin induction for 6 hrs, 3 days and 6 days, the expression of beta-III-tubulin was 1.40+/- 0.79%, 41.59+/- 3.17% and 59.11+/- 4.76% respectively. But the beta-III-tubulin expression significantly decreased 3 and 6 days after DSCAM-siRNA transfection (28.57+/- 2.91% and 43.90+/- 12.31% respectively).

CONCLUSIONSDSCAM may play an important role in MSCs differentiation into neural cells.
