AIM: To evaluate the different conditions inducing mouse embryonic stem cells (ESC) in vitro to differentiate into cardiomyocytes. METHODS: BRL conditioned medium was used to promote the growth of ESC and maintain them in an undifferentiated state. During the inducing process, retinoic acid (RA), DMSO, activin-A and TGF-? 1 were used as inducing reagents, and made up six kinds of differentiating medium. Then a three-step method inducing ESC cultured in hanging drops, in suspension and in plating was used to induce the differentiation of ESC. RESULTS: ESC were induced in vitro to differentiate into cardiomyocytes. Of all groups, the highest differentiating rate was observed in the group induced by activin-A (20 ?g/L) and TGF-? 1 (2 ?g/L). CONCLUSION: The inducing conditions including activin-A (20 ?g/L) and TGF-? 1 (2 ?g/L) is very valuable in inducing ESC differentiation into cardiomyocytes. [

This study was aimed to compare the effects of acupuncture stimulation on different acupoints, which included LR14-Qimen, ST25-Tianshu, GB34-Yanglingquanand CO11-pancreas and gallbladder (auricular vagus nerve intensively distributed areas) on gallbladder pressure and Oddi sphincter function of guinea pig, in order to discuss acupuncture effect on different acupoints in the regulation of motor function of extrahepatic biliary system. A total of 20 adult guinea pigs of both sexes were randomly divided into two groups, with 10 in each group. The detection was made on changes of Oddi sphincter electromyography and gallbladder pressure before and after acupuncture. A double-hook electrode was implanted into the Oddi sphincter for the detection of Oddi sphincter electromyography. And one small artificial balloon was put into the gallbladder to measure the intrabiliary pressure. After the guinea pig was anesthetized, changes of gallbladder pressure as well as the electromyography frequency and amplitude index of Oddi sphincter of the normal guinea pig were recorded. When the guinea pig was stabilized, acupuncture was given on LR14, ST25, GB34 and CO11 for 1 min. Observations were made on acupuncture effects of gallbladder pressure and Oddi sphincter function of guinea pig. The results showed that after acupuncture on LR14 and ST25, the electromyography frequency of Oddi sphincter was obviously increased compared with before acupuncture (frequency:P < 0.01, amplitude:P < 0.05); the gallbladder pressure was obviously decreased (P < 0.05). After acupuncture on CO11 and GB34, the electromyography frequency and amplitude index of Oddi sphincter were obviously decreased compared with before acupuncture (P < 0.05); the gallbladder pressure was obviously increased (P < 0.01). It was concluded that acupuncture on LR14 and ST25 can obviously inhibit the movement of gallbladder and promote the myoelectricity release of Oddi sphincter. Acupuncturing on CO11 and GB34 can apparently promote the shrinking movement of gallbladder and inhibit the myoelectricity release of Oddi sphincter.

Objective To investigate the correlation of the expressions of P170,topoisomerase Ⅱ(TOPⅡ)and the proliferation in gliomas.Methods Ki-67 was used as the marker of the proliferation in gliomas.The expressions of P170,TOPⅡ and Ki-67 were tested by S-P immunohistochemical technique using monoclonal antibody to their protein in 54 cases of low-grade gliomas(WHO Ⅰ～Ⅱ grade)and 54 cases of high-grade gliomas(WHO Ⅲ～Ⅳ grade),analysis of the clinical and follow-up were performed.Results The expressions of P170,TOPⅡ and Ki-67 had significant differences between low-grade and high-grade gliomas(P<0.01).Correlation analysis showed that the expression of P170 was negatively related with Ki-67(r=-0.276,P=0.019);the expression of TOPⅡ was positively related with Ki-67(r= 0.637,P<0.001);there was no correlation between the expressions of P170 and TOPⅡ.Conclusion The expressions of P170 and TOPⅡ are associated with the malignant prognosis in gliomas.

OBJECTIVETo evaluate the fatality rate of pneumoconiosis as well as the contributory factors in China in order to provide a foundation for prolonging the patients' lives.

METHODSChina National Knowledge Infrastructure (CNKI) and Wanfang Databases were searched to collect observational studies published between Jan, 2000 and Oct, 2013 on pneumoconiosis case fatality rate. Articles meeting the inclusion criteria were reviewed systematically, and analyzed by using Stata/SE 12.0, according to stage and type of pneumoconiosis and whether complicated with tuberculosis.

RESULTS41 papers were included for meta-analysis. The pooled total case fatality rate of pneumoconiosis was 31.2%. The pooled case fatality rate of pneumoconiosis patients of stage 1, 2 and 3 were 25.4%, 39.8%and 57.5%, respectively. The pooled case fatality rate of patients with silicosis, coal worker's pneumoconiosis, foundry worker's pneumoconiosis, asbestosis and cement pneumoconiosis were 35.8%, 32.4%, 24.7%, 35.1%and 5.5%, respectively. The complication with tuberculosis was a risk factor for the death of pneumoconiosis patients and the pooled RR was 1.82 (95%CI: 1.59∼2.08).

CONCLUSIONThere are significant differences in the case fatality rate of pneumoconiosis among different stages and different types of pneumoconiosis and whether complicated with tuberculosis.

Objective:To investigate the effect of tele-rehabilitation program on ataxic dysarthria following stroke.Methods:A total of 101 patients with stroke and dysarthria who received treatment at The First People's Hospital of Huzhou between January 2021 and October 2023 were included in this study. They were divided into an observation group ( n = 51) and a control group ( n = 50) using the random number table method. Patients in the control group received conventional family rehabilitation guidance, while those in the observation group participated in a tele-rehabilitation program. All patients were treated for 12 weeks. Before and 12 weeks after the intervention, the Frenchay Dysarthria Assessment (FDA) and speech clarity tests were used to assess speech function. Changes in FDA scores and speech clarity scores post-intervention were compared with pre-intervention scores. The observation group was further divided into mild, moderate, and severe groups based on FDA scores, and the differences in effect of tele-rehabilitation program on ataxic dysarthria among the three groups after the intervention were compared. Results:At 12 weeks after intervention, both the observation and control groups showed improvements in FDA scores and speech clarity [observation group: (43.88 ± 16.13) points, (68.65 ± 16.99)%; control group: (49.68 ± 12.09) points, (62.36 ± 14.20)%] compared with their baseline measurements [observation group: (55.12 ± 12.63) points, (57.96 ± 13.48)%; control group: (54.16 ± 10.69) points, (57.84 ± 12.78)%] ( t = 12.23, -14.01, 12.42, -13.86, all P < 0.001). Moreover, the observation group showed significant improvements compared with the control group ( t = 2.04, -2.01, both P < 0.05). At 12 weeks after intervention, both the mild and moderate groups showed improvements in FDA scores and speech clarity score [mild group: (31.41 ± 3.08) points, (82.94 ± 6.97)%, moderate group: (40.08 ± 4.67) points, (70.92 ± 6.26)%] compared with their baseline measurements [mild group: (42.24 ± 6.78) points, (70.53 ± 7.98)%, moderate group: (56.17 ± 4.65) points, (57.58 ± 6.54)%, t = 10.06, -20.25, 45.21, -21.34, all P < 0.001]. There were no significant improvements in the severe group for FDA scores and speech clarity score [(74.20 ± 4.29) points, (38.90 ± 5.80)%] compared with their baseline measurements [(74.50 ± 4.01) points, (37.50 ± 4.74)%, t = 1.96, -1.44, both P > 0.05]. Conclusion:The tele-rehabilitation program can improve post-stroke ataxic dysarthria, particularly showing significant effectiveness for patients with mild to moderate ataxic dysarthria.

Objective To explore the long-term clinical effect of kidney transplantation in children.Methods The clinical data of 53 children with kidney transplantation from March 2008 to September 2014 were retrospectively analyzed.The influence of the dependent factors on the estimated glomerular filtration rate (eGFR) (greater than 90 mL/min/1.73 m2 or ＜90 mL/min/1.73 m2) was estimated in the three years after the operation,and the influencing factors were analyzed by the dual logistic regression equation.Results There were 19 cases of living donors,17 cases of organ donors after death,and 6 others.The 53 patients were followed up for 3-9 years.The level of blood creatinine was decreased from the preoperative (820.1 ± 323.1) μmol/L to (51.6 ± 24.9) μmol/L 3 years after the operation (P＜0.05).eGFR was increased to (103.5 ± 11.4) mL/min/1.73 m2at 3rd year after the operation from the preoperative (17.1 ± 7.8) mL/min/1.73 m2 (P＜0.05).The age of recipients,preoperative dialysis time,number of HLA mismatching and postoperative delayed graft function healing (DGF),rejection and infection were the influencing factors of eGFR at 3rd year postoperation (P＜0.05).The multi-factor binary logistic regression equation analysis showed that only rejection was the risk factor for eGFR at 3rd year p0ostoperation.Eight cases of DGF (8/53,15.1％) recovered rapidly.There were 6 cases of acute rejection (6/47,12.8 ％) and 1 case of chronic rejection (1/47,2.1％).There were 9 cases of infection (9/47,19.1％).There were 6 cases of recurrence after surgery.The 3-year recipient and kidney survival rate was 94.3％ (50/53) and 88.7％ (47/53) respectively.The average height of the patients in the first,second and third year after the surgery was increased by (4.6 ± 1.9) cm (0.5-19.1 cm),(3.7 ± 1.8) cm (0.7-14.3 cm) and (2.8± 1.2) cm (0.3-8.7 cm) respectively.Conclusion The long-term effect of children kidney transplantation is satisfactory.

Objective To evaluate the clinical efficacy of en-bloc kidney transplantation from pediatric organ donation after death. Methods Clinical data of donors and recipients undergoing en-bloc kidney transplantation from pediatric donor kidneys were retrospectively analyzed. The 1-year survival rates of the recipient and grafted kidney were calculated. The recovery of renal function at postoperative 1 year was observed. The changes in the length of grafted kidney and incidence of postoperative adverse events were monitored. Results The 1-year survival rate of the recipients was 8/9, and 72% for the grafted kidney. During 1-year follow-up, the serum creatinine (Scr) level was down-regulated from (747± 170) μmol/L before transplantation to (83±27) μmol/L post-transplantation, the blood urea nitrogen concentration was decreased from (24.5±4.9) mmol/L to (6.8±2.0) mmol/L, and the length of transplanted kidney was increased from (61.1±9.8) mm to (100.3±1.7) mm. Two recipients suffered from delayed graft function(DGF) and restored after hemodialysis. Two cases developed acute rejection and healed after methylprednisolone shock therapy. One recipient presented with lung fungal infection at postoperative 2 weeks after transplantation, and was treated by the withdrawal of immunosuppressive agents and antibacterial treatment with poor clinical efficacy. Then the recipient died at 3rd month. One case had renal arterial thrombosis at postoperative 7 d, underwent nephrectomy at postoperative 10 d and returned to hemodialysis. At postoperative 1st month, one recipient suffered from thrombosis of unilateral renal artery. The grafted kidney in other side normally functioned and significantly grew in size at postoperative 6 months. In addition, two cases had ureterostenosis of the transplanted kidney, albuminuria in 2, abdominal aortic stenosis in 1 and urinary fistula in 1. All these symptoms were cured or alleviated after corresponding treatment. Conclusions The incidence of perioperative complications is relatively high in en-bloc kidney transplantation from pediatric organ donation after death, whereas the clinical efficacy of such kidney transplantation can be gradually increased along with the accumulation of clinical experience.
