Objective To study the clinic features and prognosis of juvenile rheumatoid arthritis (JRA)-associated iridocyclitis.Methods Ten cases of JRA -associated iridocyclitis choosed from 107 cases with JRA were reviewed and analysed.Results Polyarticular( n =9) and pauciarticular( n =1) were observed among JRA -associated iridocyclitis.Four were acute cases and all were recovered.Secondary glaucoma ( n =1) and ablepsia( n =1) were find in the chronic cases of 6,respectively.Conclusions Iridocyclitis is a common complication of JRA. Most of them are polyarticular group. The acute cases have better results compared to the chronic cases which often have more complications such as glaucoma,cataract, et al .

Objective To evaluate the development of immature oocytes after freezing-thawing by conventional cryopreservation method for mature oocytes.Methods Immature oocytes were collected from stimulated ovaries of intracytoplasmic sperm injection(ICSI)cycles.Immature oocytes were in vitro matured directly or after slow freezing-fast thawing and immunostained for tubulin and chromatin and at last visualized by confocal microscopy.Results No statistical difference was found in maturity rate between freezing groups and the controls.There was a statistically significant increase in abnormalities of chromosome(23.7% vs. 50%)and spindle(28.9% vs.53.9%)in the GV freezing group compared with the GV control(P

OBJECTIVETo investigate the pathogenesis of globozoospermia, fertilization ability of round-headed sperm, and the application value of assisted oocyte activation in intracytoplasmic sperm injection (ICSI) for the wives of glohozoospermia men.

METHODSWe collected oocytes from the wives of 2 globozoospermia patients and randomly divided them into two groups after ICSI to receive calcium ionophore A23187-activation and conventional treatment, respectively. We reviewed the relevant literature published at home and abroad, and discussed the etiology of globozoospermia, fertilization ability of round-headed sperm, and treatment options for this disease.

RESULTSQuality embryos were obtained in the A23187-activation group while no fertilized oocytes, oocyte cleavage, quality embryos, or blastular formation were found in the conventional treatment group. Both women achieved pregnancy and gave birth to healthy neonates after transfer of the quality embryos from the A23187-activation group.

CONCLUSIONCalcium ionophore A23187 can be applied to ICSI for the wives of globozoospermia men and bring about desirable clinical outcomes. Meanwhile, attention should be paid to its safety.

Objective To observe the clinical efficacy of wrist-ankle acupuncture plus bloodletting cupping in treating diabetic peripheral neuropathies (DPN). Method A total of 120 patients were randomized into two groups by using the random number table. Sixty cases in the treatment group were intervened by wrist-ankle acupuncture plus bloodletting cupping; sixty cases in the control group were treated with Mecobalamin tablets. The clinical efficacies were evaluated and electroneurogram was tested after 28-day treatment. Result The total effective rate was 95.0% in the treatment group versus 88.3% in the control group. The clinical efficacy of the treatment group was significantly superior to that of the control group (P<0.05). The treatment group was significantly better than the control group in comparing the major symptoms and signs including numbness, pain, and weakness in limbs (P<0.05); there were no significant between-group differences in comparing symptoms including cold limbs, short of breath and unwilling to speak, lassitude, and thirsty with desire to drink (P>0.05). The treatment group had better effect than the control group in comparing the motor conduction velocity of superficial peroneal nerve and sensory conduction velocity of common peroneal nerve (P<0.05). Conclusion Wrist-ankle acupuncture plus bloodletting cupping is effective in treating DPN, and it benefits the recovery of motor and sensory function of the impaired peripheral nerves.

Objective:To observe the effect of electroacupuncture (EA) on the expressions of acetylcholine (ACh) and mucin 5AC (MUC5AC) in the lungs of rats with chronic obstructive pulmonary disease (COPD),and explore the mechanism of EA in treating COPD.Methods:Thirty Sprague-Dawley (SD) rats were randomly divided into a control group,a COPD group,and an EA group,with 10 rats in each group.The control group was a group of normal rats.The COPD rat model was induced by cigarette smoke combined with lipopolysaccharide (LPS).The COPD rats were treated with EA at bilateral Feishu (BL 13) and Zusanli (ST 36) in the EA group,30 min each time,once a day,successively for 14 d.The lung function was tested.The contents of ACh and MUC5AC in lungs and bronchoalveolar lavage fluid (BALF) were detected by enzyme-linked immunosorbent assay (ELISA).Pearson method was used to analyze the correlation between pulmonary function and the content of MUC5AC in lungs.The mRNA and protein expressions of MUC5AC in lung tissues were detected by real-time polymerase chain reaction (RT-PCR) and Western blot (WB),respectively.The immune response of MUC5AC was observed by immunohistochemistry.Results:Eight rats were left in each group,and the other two died.Compared with the control group,the total airway resistance (Raw) increased significantly and dynamic compliance (Cdyn) decreased significantly in the COPD group (P＜0.01);compared with the COPD group,the Raw level declined significantly and Cdyn increased significantly in the EA group (P＜0.01).The contents of ACh and MUC5AC in the lungs and BALF were remarkably higher in the COPD group compared with those in the control group (P＜0.01,P＜0.001);compared with the COPD group,the contents of ACh and MUC5AC were significantly lower in the EA group (P＜0.05,P＜0.001).There was a negative correlation between MUC5AC content and lung function (P＜0.001).The mRNA and protein expressions of MUC5AC in the lungs were significantly higher in the COPD group than in the control group (P＜0.001);compared with the COPD group,the expressions were significantly lower in the EA group (P＜0.01).Compared with the control group,the immune response of MUC5AC in the airway epithelium significantly increased in the COPD group (P＜0.001);the immune response of MUC5AC was significantly lower in the EA group compared with that in the COPD group (P＜0.001).Conclusion:EA treatment can improve the lung function of COPD rats,which may be related to its effect in the down-regulation of ACh and MUC5AC contents in the lungs as well as the inhibition of mucus hypersecretion.

OBJECTIVETo observe the effects of mesenteric lymph drainage on erythrocyte rheology and blood viscosity in hemorrhagic shock rats.

METHODSWistar rats were randomly divided into sham-shock group, shock group (establishing hemorrhagic shock model), drainage group (establishing hemorrhagic shock model plus drainaging shock mesenteric lymph from hypotension 1 h). At 3 h of hypotension or corresponding time, blood samples were harvested from the abdominal aorta for determining the erythrocytic parameters, erythrocyte electrophoresis, erythrocyte sedimentation rate (ESR) and blood viscosity, and the erythrocytes aggregation index and erythrocyte deformability index were calculated.

RESULTSCompared with the sham-shock group, the red cell contents, hematocrit (HCT), hemoglobin (Hb), mean corpuscular hemoglobin concentration (MCHC), erythrocyte electrophoretic rate and mobility, erythrocyte deformability index, whole blood viscosity, whole blood relative or reduced viscosity at low and high shear rates in shock group were observably lower, and mean corpuscular volume, electrophoretic time of erythrocyte, ESR, K value of equation and K value of emendation, erythrocytes aggregation index, plasma viscosity in shock group were increased markedly; the MCHC, erythrocyte electrophoretic rate and mobility, whole blood viscosity, whole blood relative viscosity at low and high shear rates in drainage group were reduced, and the red blood cell volume distribution width -SD (RDW-SD) was increased remarkably. At the same time, in drainage group, the HCT, RDW-SD, erythrocyte deformability index, whole blood viscosity and relative viscosity at low and high shear rates were higher, the ESR, K value of equation and K value of emendation, erythrocytes aggregation index, plasma viscosity were lower than that of shock group.

CONCLUSIONThe results indicate that the mesenteric lymph drainage could improve the erythrocyte rheological behavior, as a result, improve the hemorrheological properties in hemorrhagic shock rats.

OBJECTIVETo explore the clinical effect of low dose pituitrin in children with septic shock.

METHODSA total of 48 pediatric cases with septic shock, in whom 6 hours, conventional treatment could not reverse shock from January 2008 to December 2010, were selected for this study. The patients were divided into two groups randomly (completely random design) (control group 24, remedial group 24). The conventional treatment included antibiotics/fluid resuscitation/correcting acid-base imbalance, glucocorticoid, organ (heart/lung) support, dopamine 1 - 15 µg/(kg·min) and norepinephrine 0.5 - 2 µg/(kg·min) pumped in continuously in the control group. In initial 6 hours the same treatment was given to the remedial group, while low dose pituitrin (0.01 - 0.03 U/min) was pumped additionally during the rest of time. The therapeutic effect on correcting shock was evaluated in both groups.

RESULTSThe total effective rate was 76.2% in the remedial group and 40.0% in the control group; the mortality was 33.3% and 60% respectively. The difference between both groups was significant (P = 0.025).

CONCLUSIONLow dose pituitrin could improve the clinical effect significantly in children with septic shock in whom 6 hours conventional treatment failed to correct shock, shorten the total periods of treatment, and decrease mortality.

OBJECTIVETo compare the effects of the cryoprotectant containing glucose and that containing sucrose on the motility of post-thaw human sperm.

METHODSThe cryoprotectant containing glucose and that containing sucrose were applied to 50 semen samples and the motility of the post-thaw human sperm was compared before and after cryopreservation and between the study groups.

RESULTSThe forward motility and total motility of the sperm were (58.4 +/- 5.7)% and (63.4 +/- 6.1)% before cryopreservation, (43.8 +/- 7.6)% and (48.4 +/- 7.6)% after thawing with the cryoprotectant containing glucose, and(42.6 +/- 8.9)% and (48.0 +/- 8.5)% after thawing with the cryoprotectant containing sucrose. Decreased sperm motility was observed after cryopreservation, with statistic significance (P < 0.01). There was no significant difference in the forward and total motility of the post-thaw sperm between the two cryoprotectants.

CONCLUSIONCryopreservation inflicts obvious damage on sperm. Sucrose is a feasible sperm cryoprotectant.

Preparation of a poly (gamma-glutamic acid)-cisplatin conjugate was introduced and its in vitro antitumor effect was investigated. Poly (gamma-glutamic acids) was obtained by using fermentation methods. The hydrolyzed small molecular weight of poly (gamma-glutamic acids) was prepared by acid hydrolysis. The interaction between poly (gamma-glutamic acids) -cisplatin conjugate (PGA-CDDP) and DNA was investigated by PCR model. MTT assay was used to investigate the in vitro anticancer activity of the conjugate. Apoptosis assay of the conjugate was investigated by FCM assay and the in vivo toxicity was also proceeded. The results showed that the poly (gamma-glutamic acids) -cisplatin conjugate was obtained successfully and its yield is 10% - 12%. It has obvious antitumor effects on human liver tumor BEL7404 cells, human lung tumor H446 cells and human colon tumor RKO cells. At the same time, it also has apoptosis effects on the three kinds of tumor cell lines. The in vivo toxicity of PGA-CDDP was examined in normal mice and the results showed that the in vivo toxicity of this conjugate was significantly lower than that of free CDDP. In conclusion, the poly (gamma-glutamic acids) -cisplatin conjuate could be used as a potential clinic antitumor drug. The poly (gamma-glutamic acids) obtained by fermentation can be used as a valuable drug carrier system.
