ABSTRACT
Objective:To investigate the relationship between peritoneal thickness and baseline solute transport function in peritoneal dialysis (PD) patients, and analyze the factors affecting the function of peritoneal transport.Methods:Non-diabetic end-stage renal disease (ESRD) patients admitted to the Second Hospital of Longyan City from January 2017 to June 2019 were enrolled in this study. The thickness of the peritoneal membrane was measured by color ultrasound instrument before the peritoneal catheterization. Standard peritoneal equilibration test (PET) was performed after one month of peritoneal dialysis. The ratio of corrected creatine in 4 h dialysate to 2 h serum creatine (D/Pcr) was used as a solute baseline transport index, and according to the D/Pcr evaluation results, the patients were divided into high/high average transfer (H) group (D/Pcr≥0.65) and low/low average transfer (L) group (D/Pcr<0.65). The clinical data, peritoneal thickness and peritoneal dialysis related indicators between the two groups of patients were compared. Binary logistic regression was used to analyze the factors affecting the function of peritoneal transport.Results:The amount of peritoneal ultrafiltration in H group was significantly lower than that in L group, intraperitoneal creatinine clearance (Ccr) and peritoneal thickness were significantly higher than those in L group (both P<0.05). Pearson and Spearman correlation results showed that the thickness of peritoneal membrane positively correlated with D/Pcr ( r=0.673, P<0.05), peritoneal Ccr ( r=0.261, P<0.05), and negatively correlated with ultrafiltration of peritoneal dialysis ( r=-0.365, P<0.05). Partial correlation analysis showed that the peritoneal thickness was positively correlated with the solute transport index D/Pcr ( r=0.539, P<0.05) and the peritoneal Ccr ( r=0.338, P<0.05). Binary logistic regression results showed that peritoneal thickening was a risk factor affecting peritoneal transport function ( OR=1.175, 95% CI 1.009-1.369, P<0.05). Conclusions:There is a positive correlation between the peritoneal membrane thickness and the baseline solute transport index in patients with non-diabetic peritoneal dialysis. Peritoneal thickening is a risk factor affecting peritoneal transport function.
ABSTRACT
Objective@#To observe the clinical effect of shock waves combined with movement therapy in the treatment of temporomandibular joint dysfunction.@*Methods@#Forty patients with class-Ⅲ temporomandibular joint function disorders were randomly divided into an observation group and a control group, each of 20. In addition to the exercise therapy, the observation group was provided with extracorporeal shock wave therapy, while the control group was given ultrashortwave therapy. The intervention lasted for 4 weeks for both groups. Before and after the intervention, discomfort was quantified using a visual analogue scale, and maximum mouth opening and Fricton′s temporomandibular joint function index were measured for both groups.@*Results@#There was no significant difference between the two groups before the intervention. After the treatment the average discomfort rating and maximum mouth opening were significantly better in the observation group. The observation group′s average Fricton index was also significantly better.@*Conclusion@#Extracorporeal shock waves can be combined with movement therapy to significantly relieve the pain of patients with temporomandibular joint dysfunction. It can improve their maximum mouth opening and the functioning of the temporomandibular joint.

ABSTRACT
The relatively independence and separation in the teaching of clinical medicine and basic medicine limits the ability training of students,and the combination of basic and clinic medicine in teaching has become the core issues and trends in medical teaching reform.So the conventional teaching patterns were reformed in pathophysiology by applying combination of basic and clinic medicine in teaching.In order to accelerate medical students to early exposure to clinical medicine Bengbu medical college changed the teachers' teaching ideas,promoted the local integration of the courses of basic and clinical medicine and the combination of basic and clinic medicine teachers in teaching,reformed mechanisms in teaching management and teaching operation.We also tested the preliminary reform effects by way of students' evaluation of the teaching and examination,and discussed the unfavorable factors affecting the educational reform and thought out some countermeasures.
ABSTRACT
Objective To investigate the influence of proprioceptive training of hemiplegic stroke patients on their visually compensatory dependence.Methods Twenty stroke patients without vestibular abnormalities were recruited.They were able to walk for 10 meters.All the patients underwent 4 weeks of rehabilitation training including proprioceptive training,treadmill exercises and isometric muscle strengthening.Static standing balance test was performed before and after 4 weeks of treatment.The parameters such as the anteroposterior and mediolateral sway of the center of gravity,center of gravity distribution were analyzed before and after the treatment,taking into consideration of visual feedback (eyes open or closed) by using t-test and multiple linear regression analysis.Results Visual feedback had significant no influence on the anteroposterior sway of center of gravity before and after training (P ＞ 0.05) ; Visual feedback had significant influence on mediolateral sway of center of gravity.Rehabilitation training significantly improved the mediolateral sway in opened-eye standing (P ＜ 0.05) but not closedeye standing (P ＞ 0.05).Visual feedback played significant role in center of gravity distribution after training (P ＜ 0.05).Conclusions Visual compensation is of significant influence on the mediolateral sway.Proprioceptive training can help decrease the patient's dependence on visual feedback and enhance the patient's balance ability.

To explore the mechanism of immune escape in tumor.Methods Peripheral blood mononuclear cells (PBMC) were cultured with different concentration of tumor cell culture supernatant. Cell proliferation was examined with standard cytometry and MTT. The apoptotic rate and immune phenotype were analyzed by FACS. The level of IL-2 was determined with ELISA.Results Adding HepG2 supernatant, there was no significant influence in activation of lymphocyte, but the proliferation rat and the secretion of IL-2 were obviously decreased. The lymphocyte apoptosis rate was raised.Conclusion The tumor cell may produce a certain soluble protein, thus escape from the immune surveillance of tumor-bearing host.
ABSTRACT
85%. The concentrated MCS in different amount was added to the IFN-?(100 pg/mL) and LPS (10 ng/mL) enriched culture media. The IL-12 production by monocytes was determined by the enzyme- linked immunosorbent assay(ELISA).The expression of CD14 and CD1a was analyzed by flow cytometry 5 days after the monocytes were co-cultured with MCS. Results The production of monocytic IL-12 was down-regulated by MCS in a dose dependent manner. The amount of IL-12 from monocytes decreased along with an increased dose (25-100?L) of MCS applied in the reaction. It was also observed that the differentiation from CD14 expressing monocytes to CD1a dendritic cells was impaired by MCS. The ability of MCS to inhibit the production of IL-12 by monocytes and to suppress the differentiation of monocytes to dendritic cells in vitro could be disrupted by PD98059,an ERK specific inhibitor. Conclusions MCS appears to inhibit IL-12p40 production by monocytes and inhibit differentiation of monocytes in vitro via secretion of ERK stimulating factor. The inhibitory factors in MCS and their chemical natures need further research.
