Objective To observe the clinical efficacy of acupoint sticking plus hot compress by moxa-salt bag in treating constipation after acute cerebral stroke.Method Eighty patients with constipation after cerebral stroke were randomly allocated to a treatment group and a control group by using random number table method according to registration order, 40 cases each. The control group was intervened by acupoint sticking at umbilicus with rawDa Huang (Rheum Officinale), and the treatment group was additionally given hot compress using moxa-salt bag. The treatment was given once a day, for consecutive 3 days in total. The first defecation time, stool shape and defecation sensation were observed in the two groups. The clinical efficacies were compared between the two groups.Result The total effective rate was 90.0％ in the treatment group versus 72.5％ in the control group, and the difference was statistically significant (P<0.05). After the treatment, there was statistically significant difference in comparing the first defecation time between the two groups (P<0.05). After the treatment, the incidence rate of soft stool was 85.0％ and that of hard stool was 15.0％ in the treatment group versus 40.0％ and 60.0％ in the control group, and the differences were statistically significant (P<0.05). The incidence rate of pleasant defecation sensation was 80.0％ and that of difficult defecation was 20.0％ in the treatment group versus 35.0％ and 65.0％ in the control group after the treatment, and the differences were statistically significant (P<0.05).Conclusion Acupoint sticking plus hot compress by moxa-salt bag is an effective method in treating constipation after acute cerebral stroke.

Objective To reinvestigate the value of overnight low-dose dexamethasone suppression test in the diagnosis of Cushing syndrome.Methods Fifty-two patients with Cushing syndrome and 153 patients with simple obesity or essential hypertension in whom Cushing syndrome was excluded were studied retrospectively in order to compare the sensitivity and specificity of different serum cortisol cut-off levels in overnight 1 mg dexamethasone suppression test in the diagnosis of Cushing syndrome.Results The sensitivity of 50% of basal serum cortisol level at 8:00 and of the serum cortisol cut-off levels of 275,200,138,50 nmoL/L at 8:00 after the overnight 1 mg dexamethasone suppression test was 92.3%,92.3%,92.3%,92.3% and 100.0% respectively, and the specificity was 90.8%,98.7%,96.1%,91.5% and 78.4%,respectively.Conclusion The serum cortisol cut-off level of 50 nmol/L in the overnight 1 mg dexamethasone suppression test has very high sensitivity and can be used as a screening test for Cushing syndrome.

Objective To explore the standard clinical pathway and stratified cost insurance in patients with senile cataract operation. Methods Patients treatment by senile cataract phacoemulsification combined with IOL implantation were selected as research subjects by cluster sample from two hospitals from 2013 to 2014 . Patients were divided into different groups according to the year, chronic diseases, preoperative waiting time. The difference of hospitalization expenses and hospitalization time were compared. Different levels of hospital costs were established by CHAID decision tree used hospitalization cost as target variable. Results The waiting time for operation was 2 days, the total hospitalized time was 5 days and these can be used as reference time in clinical pathway. Patients uninsured or with long waiting time for operation had longer hospitalized time. Chronic disease, terms of payment and waiting time before operation were point factors that effect the hierarchical of decision tree. Conclusion The new standard of clinical path need to adjust constantly. Distinguish different patients condition and pay different clinical path costs.

Objective To study the changes of mRNA and protein expressions of Kras gene in thymic lymphomas induced by ionizing radiation,and to detect the methylation of CpG islands in promoter region of Kras gene,then to investigate the mechanisms for the occurrence of radiation carcinogenesis.Methods The thymic lymphoma models of BALB/c mice were made by X-ray irradiation,then the total RNA was extracted,cDNA was synthesized and the total protein was extracted from both thymic lymphoma tissue and normal thymus tissue;the mRNA and protein expressions of Kras gene in thymic lymphoma tissue and normal thymus tissue were detected by RT-PCR and Western blotting method, and the methylation of CpG islands in promoter region of Kras gene was detected by bisulfite sequencing PCR. Results The mRNA expression level of Kras gene in thymic lymphoma tissue was significantly higher than that in normal thymus tissue(P<0.01).The protein expression level in thymic lymphoma tissue was about 1.41 times higher than that in normal thymus tissue;4 CpG sites were methylated detected by bisulfite sequencing PCR in normal thymus tissue, however, 1 CpG site was methylated in thymic lymphoma tissue,the CpG islands in promoter region of Kras gene were demethylation state in thymic lymphoma. Conclusion Ionizing radiation can cause the changes of mRNA and protein expression levels of Kras gene in thymic lymphoma tissue by demethylation state of Kras gene,eventually lead to the occurrence of tumor;it might be one of the mechanisms for the occurrence of radiation carcinogenesis.

OBJECTIVETo analyze and evaluate the acceptability of mifepristone compatible with misoprostone versus conventional surgical abortion among women under unwanted early pregnancy, so as to help the unexpected pregnant women to choose the satisfactory abortion, and to provide the evidence for clinicians to make a proper clinical decision.

METHODSSix medical databases were searched, including MEDLINE, EMBASE, Cochrane library, CBMdisc, CNKI and VIP, together with twelve journals hand-searched, and references of included studies additionally searched. Two qualified reviewers reviewed the original articles, evaluating qualities of articles, and extracting data independently. After heterogeneity test, the data was pooled using Revman software if capable, or descriptive analysis was applied.

RESULTSIn total, nine original clinical controlled trials were included, containing 3565 cases. Before abortion, more unwanted pregnant women chose the medical abortion because they believed medical abortion was less painful than surgical abortion (OR = 466.51, 95% CI: 91.37 - 2381.88), but medical abortion was less time-consuming than surgical abortion (OR = 0.02, 95% CI: 0.01 - 0.06). After abortion, satisfaction with medical abortion was similar to that with surgical abortion, with insignificant difference (P = 0.89). However, second choice and recommendation rates of medical abortion were much higher than those of surgical abortion with OR and 95% CI as 2.72, 2.13 - 3.47 and 4.19, 2.16 - 11.16, respectively.

CONCLUSIONSMedical abortion was less painful than surgical abortion and the rate of second choice and recommendation to others were all also higher than those of surgical abortion. However, the process of medical abortion was not as quick as surgical abortion but the satifacation of both methods seemed similar. Therefore, the two artificial abortion methods were not recommended to replace each other at the present time.

Objective To analyze and compare the imaging features of chromophobe cell renal carcinoma(CCRC)with pathologic findings in order to improve the diagnostic accuracy.Methods The data of CT and MRI of 12 patients with CCRC were reviewed retrospectively.Ten patients underwent CT examination,including precontrast scan,the contrast eortieomedullary phase scan and the parenchymal phase scan(one patient without corticomedullary phase scan).Two patients underwent MR examination including precontrast T_1WI,T_2WI and enhanced T_1WI of the corticomedullary phase and the parenchymal phase.Results Four lesions located in left kidney and eight in right kidney.Maximum diameter of lesions ranged from 24 mm to 125 mm,average 56.7 ram.Homogenous density was observed in six lesions of ten on unenhanced CT scan and five lesions had homogenous enhancement on enhanced CT scan,which was due to the less incidence of necrosis,liquefaction and hemorrhage on pathologic findings.Nine Lesions showed hyperdense compared with renal medulla but the density was lower than renal cortex on the corticomedullary phase.The enhanced degree was positively correlated with microvessel density(MVD).All ten lesions became hypodense compared with renal medulla on the parenchymal phase scan.Central stellate scar was found in two big lesions and psudocapsula were observed in four lesions confirmed by pathology.Two patients underwent MRI examination.Compared with medulla,the two lesions showed hyperintense on unenhanced T_1WI and obviously hypointense on unenhaneed T_2WI.The enhancement pattern of them was similar to CT. Conclusion The imaging features of CCRC,such as homogeneity,special enhancement pattern and distinct hypointensity on T_2WI,help to differentiate CCRC from other renal tumors.

OBJECTIVETo summarize the clinical features and to evaluate outcomes and to assess therapeutic effects in 34 children and adolescents with Hodgkin lymphoma treated with risk-adapted combination chemotherapy and low-dose, involved-field radiation therapy (IFRT) in China.

METHODFrom January 2003 to April 2009, 34 hospitalized children with Hodgkin lymphoma were enrolled into the BCH-HL 2003 protocol (revised CCG 5942) in our hospital. Pathological samples were reviewed centrally and classified based on the World Health Organization guidelines. Staging was based on clinical evaluation and was defined by the Ann Arbor staging system. The 34 patients were treated according to the different risk factors in three treatment groups (standard, intermediate, and high risk), and received risk-adapted combination chemotherapy and IFRT. All analyses were calculated by the statistical program SPSS.

RESULTOf the 34 Hodgkin lymphoma patients, 28 were male and 6 were female. The median age was 8.7 years (range from 4 years to 15 years) at the time of diagnosis. In terms of clinical presentation, 53% had bulky lymph nodes, 47.1% had more than 4 node regions involved and 44% had "B" symptoms at presentation. The distribution for stage of disease was 0% for Stage I, 21% for Stage II, 35% for Stage III and 44% for Stage IV disease. All patients had classical histology consisting of three different sub-discipline: 22 cases of mixed cellularity (64.7%). In pathological samples of 25 cases there was EBV encoded RNA (EBER) or latent membrane protein (LMP) staining. The overall survival (OS) was 100% and the 5-year event-free survival was 94.1% with a median follow-up of (26.1 ± 16.3) months. Two patients had early relapse after treatment was finished. Organ toxicity was limited to hematological grades III and IV at rates of 40% and 71% respectively.

CONCLUSIONChildhood Hodgkin lymphoma in our study was more frequently seen in male school aged children. Combined-modality therapy using risk-adapted chemotherapy with radiation is effective and well tolerated. The overall prognosis was good.

OBJECTIVETo explore the role of inflammatory reaction mediated by p38-mitogen activated protein kinase (p38-MAPK) signal path on prevention and treatment of Parkinson disease (PD) model rats by electroacupuncture (EA).

METHODSThirty-two healthy male SD rats were randomly divided into a normal group, a sham operation group, a model group and an EA group, eight rats in each one. The PD model was established in the model group and EA group by subcutaneous injection of rotenone in skin-back area (2 mg/kg, dissolved in sunflower oil, 2 mg/mL in density), while the injection of sunflower oil emulsion without rotenone at the same point and quantity as the model group was applied in the sham operation group. The normal group was not given any intervention. The EA treatment (continuous wave, 2 Hz in frequency, 1 mA in intensity, 20 min) was applied at "Fengfu" (GV 16) and "Taichong" (LR 3) in the EA group, once a day for continuously 14 days. No treatment was given in the other groups. The expression of tyrosine hydroxylase (TH), phosphorylated p38-MAPK, cyclooxygenase-2 (COX-2) in the substantia nigra were detected with immunohistochemical method.

RESULTSThere was typical PD ethology change in the model group. Compared with the normal group and sham operation group, the expression of TH positive neuron in the substantia nigra in the model group was significantly decreased, while the expression of phosphorylated p38-MAPK and COX-2 were significantly increased (all P < 0.01). Compared with the model group, the expression of TH positive neuron in the EA group was apparently increased, while the expression of phosphorylated p38-MAPK and COX-2 were significantly decreased (all P < 0.01).

CONCLUSIONThe EA therapy could obviously reduce the expression of inflammation mediator COX-2, inhibit the phosphorylation of p38-MAPK, reduce the damage of dopaminergic neurons in the rats with PD, and this effect may be related with the impact of p38-MAPK signal path
