Objective To investigate the role of regulatory B cells (Breg)in children with newly diagnosed immune thrombocytopenia (ITP).Methods A total of 35 newly diagnosed ITP children admitted to the Pediatric De-partment,the First Affiliated Hospital of Zhengzhou University from January to December 201 4 were recruited in this study,and another 20 gender -and age -matched healthy children from the Department of Medical Examination Center of the same Hospital were recruited as controls during the same period.Peripheral blood samples (3 mL from each chil-dren)were collected from all the newly diagnosed ITP children and the normal controls.Breg cells were tested by Flow Cytometry,and the expression levels of interleukin -1 0 (IL -1 0)and transforming growth factor -β1 (TGF -β1 ) mRNA were measured by real time fluorescence quantitative polymerase chain reaction.Meanwhile,the correlation be-tween Breg cells and the expression levels of IL -1 0,TGF -β1 mRNA were analyzed by Pearson correlation.Results The percentages of Breg cells in the peripheral blood of the newly diagnosed ITP children [(2.37 ±0.67)%]were sig-nificantly lower than those of the normal controls [(4.92 ±1 .32)%],and there was a significant difference (t =-7.47,P =0.000);the expression levels of IL -1 0 mRNA in the newly diagnosed ITP children(0.202 ±0.059) were significantly decreased compared with those of the normal controls(0.41 5 ±0.21 2),and there was a significant difference(t =-5.1 75,P =0.000);while the expression levels of TGF -β1 mRNA in the newly diagnosed ITP chil-dren(1 .587 ±0.823)were significantly increased than those in the normal controls(0.61 9 ±0.322),and there was a significant difference(t =4.081 ,P =0.001 ).There was a significant positive correlation between Breg cells and the ex-pression levels of IL -1 0 mRNA(rs =0.828,P <0.05),but no correlation between Breg cells and expression level of TGF -β1 mRNA was found (rs =0.527,P =0.1 1 7).Conclusions The decrease expressions of Breg cells can be found in the newly diagnosed ITP children,and the abnormal expression of Breg cells may play a key role in the immu-nological pathogenesis of the newly diagnosed ITP children.

Objective To explore the effects of the neotype hand-arm sling on shoulder subluxation and transferring movement in hemiplegic stroke patients.Methods Thirty hemiplegic stroke survivors with shoulder subluxation and poor elbow flexor muscle tone (＜2 on the Modified Ashworth Scale).were selected and randomly divided into three groups.Group 1 was trained in static upright standing,plus 10 min of sit-to-stand training and 20 min of walking training with no support for the hemiplegic,subluxed shoulder.Group 2 did the same training using a bagtype shoulder sling,and group 3 used the neotype hand-arm sling.Index finger palpation was used to evaluate the degree of shoulder subluxation,and the Five Times Sit-to-Stand (FTSST) and Timed Up-and-Go (TUG) times for the three groups were compared.Results In the static standing training,both the bag-type sling and the neotype hand-arm sling could effectively reduce shoulder subluxation.However,after 10 min of sit-to-stand training the neotype hand-arm sling was found to be significantly superior to the bag-type shoulder sling in improving shoulder subluxation,with the latter having no effect on shoulder subluxation.In the 20 rin of walking training,the neotype hand-arm sling provided significantly more effective support than the bag-type shoulder sling,although both could support the shoulders.Those using the neotype sling had shorter FTSST times,though there were no significant differences in the average TUG times.Conclusions The neotype slings can more effectively counter shoulder subluxation in upright stance,especially during sit-to-stand maneuvers and walking.It might have positive effects on transferring ability.

Aim: To evaluate the effects of bioactive extracts from Fructus Jujubae in attenuating the inflammation induced by Radix Kansui. Methods: Exoteric splenic lymphocyte ( SPL) of mouse and peritoneal macrophage ( PMψ) of rat were used as cell model to evaluate the anti-inflammatory effects of fractions from Fructus Jujubae. MTT method was used to assay SPL proliferation, and Griess method was used in NO release of PMψ. Firstly, Radix Kansui fraction was applied to induce inflammatory effects of the cells, and then, the anti-inflammatory effects of five extracts of Fructus Jujubae were investigated to determine the active fractions in Fructus Jujubae, which probably contribute to the attenuation of Radix Kansui. The effects of Fructus Jujubae extract in interfering the gastrointestinal acute damages caused by the extract of Radix Kansui were observed according to the pathological sections of mice. Results: The extract RK-3 ( diterpenes) exhibited the most significant pro-inflammatory effect. The bioactive extracts B (micromolecule saccharides and amino acids), D(flavonoid glycosides), and E (triterpenes) of Fructus Jujubae could attenuate the action of RK-3. The effective extract of Fructus Jujubae protected stomach and duodenum of mouse from acute damages caused by the extract of Radix Kansui. Conclusion: Fraction RK-3 (diterpenes) of Radix Kansui had pro-inflammatory effects, and some extracts of Fructus Jujubae could attenuate this effect of Radix Kansui. The results helped to clarify that Fructus Jujubae attenuates the toxic effect of Radix Kansui in certain cases, and the bioactive extracts of Fructus Jujubae discovered in the experiments offer the basis for further research to the active components of Fructus Jujubae.

Objective To provide Meta-analysis evidence of laparoscopic partial nephrectomy (LPN) vs open partial nephrectomy (OPN) in assisting clinical decision making.Methods By searching CHKD,PUBMED,Wanfang and VIP database self-built library up to June 30,2012,both Chinese and English literatures of LPN and OPN efficacy in controlled study were included with strict exclusion criteria by two independent screenings of the literature.Data extraction and quality assessment were done by using the RevMan 5.1 META analysis software.Results A total of four English and six Chinese literature were included in this Meta-analysis.There were 1636 cases of partial nephrectomies.Of these patients,794 cases were treated with LPN,842 cases were treated with OPN.Meta analysis results showed that:in terms of operative time (SMD =0.10,95％ CI-O.40-0.59,P =0.70),surgical complication (OR =1.03,95％ CI0.73-1.44,P =0.88),positive surgical margin (OR =1.64,95 ％ CI0.83-3.23,P =0.16),warm ischemia time (SMD =1.07,95％ CI-0.02-2.16,P =0.05),postoperative tumor recurrence (OR =0.58,95％ CI 0.26-1.30,P =0.18),there was no significant difference.But in terms of intraoperative blood loss (SMD=-1.08,95％CI-1.57--0.59,P＜0.01),postoperative hospital stay (SMD=-0.81,95％CI-0.97--0.65,P ＜0.01),the differences were significant in favor of LPN.Conclusion Comparing with OPN,LPN has advantages in intraoperative blood loss and post-operative hospital stay,no obvious advantages in operative time,surgical complications,positive surgical margin,warm ischemia time and tumor recurrence.

Objective To observe the effects of ICB orthopedic sole combined with rehabilitation training on balance and walking function in stroke survivors.Methods Thirty hemiplegic stroke patients were recruited and divided into a study group (n =15) and a control group (n =15) by using a random number table.Both groups took exercises based on the principles of a motor relearning program and conducted core stability control training,and the study group additionally undertook hemiplegic lower extremity weight-bearing exercises and walking with ICB orthopedic sole used in daily living.The program was administered 20 min twice per day for 4 weeks.All patients were evaluated with Rest Calcaneus Standing Position (RCSP),Malleolar Position (MP),Forefoot Position (FP),Berg Balance Scale (BBS),l0 m Maximum Walking Speed (MWS) and walking section of Motor Assessment Scale (MAS)before and after the program.Results After 4 weeks of intervention,all the measurements except the FP in both groups improved significantly,and significant differences were observed between the two groups.After 4 weeks of training,the average RCSP (1.78 ± 0.32) ° and MP (13.33 ± 2.51)° were improved significantly compared to those of the control group [(2.58 ± 0.59) ° and (12.45 ± 3.31) °,respectively].Moreover,the average BBS,MAS and MWS improved significantly compared to the control group.Conclusions ICB orthopedic sole combined with rehabilitation training can improve the weight-bearing,balance and ambulation abilities of stroke survivors.
