OBJECTIVETo compare the efficacy between moxa salt packets at acupoints combined with tropisetron hydrochloride and single use of tropisetron hydrochloride for cisplatin chemotherapy-induced gastrointestinal reaction.

METHODSSixty patients with malignant tumor who met inclusive criteria and received chemotherapy for the first time were recruited and randomly divided into an observation group and a control group, 30 cases in each one. Between the first days and fifth day into the chemotherapy, the patients in the control group were treated with daily intravenous injection of tropisetron hydrochloride (5 mg), while patients in the observation group, based on the treatment of control group, were treated with moxa salt packets at Zhongwan (CV 12). The nausea and vomiting between the first days and fifth day into the chemotherapy were compared in the two groups, and the occurrence rates of adverse reactions within the first week into chemotherapy were recorded.

RESULTSBetween the second day and fifth day into the chemotherapy, the effective rate for nausea in the observation group was higher than that in the control group (all P < 0.05); between the third day and fifth day into the chemotherapy, the effective rate for vomiting in the observation group was higher than that in the control group (all P < 0.05); one week into the chemotherapy, the occurrence rate of constipation in the observation group was lower than that in the control group (P < 0.05).

CONCLUSIONThe moxa salt packets combined with tropisetron hydrochloride can effectively reduce the cisplatin chemotherapy-induced nausea and vomiting as well as the occurrence rate of delayed-type vomiting, and improve the constipation, which is superior to single use of tropisetron hydrochloride.

Objective To assess the role of helical CT in the long-term follow-up of patients with malignant hepatic tumors treated with RFA. Methods CT findings of patients with liver malignant tumors (29 hepatocellular carcinomas and 7 metastases) were reviewed retrospectively, who underwent percutaneous ultrasound-guided radiofrequency ablation (RFA). CT images consisted of nonenhanced and dual-phase contrast-enhanced helical CT scan, the effect of ablation therapy and tumor recurrence were detected. Results The major patterns of tumor residual or local recurrence were the lesions with thick rim or nodular peripheral enhancement in arterial phase or the lesions with gross enlargement on follow-up CT images. The complete necrosis lesions in 28 cases (77.8%) were seen on the initial postablation CT scans after a single session RFA. On the subsequent follow-up CT examination, the local intra-hepatic tumor recurrences were seen in 2 cases (5.6%) as well as the remote intra-hepatic tumor recurrences were seen in 4 cases (11.1%).Conclusion For certain patients with hepatic malignant tumors, RFA is an effective therapeutic method, and dual-phase contrast enhanced helical CT scans play a important role in long-term assessment and follow-up of patients.

Objective To investigate the clinical effect of low molecular weight heparin (LMWH) and pressure pump on perioperative deep vein thrombosis (DVT) in patients with hip fracture and analyze the effect of LMWH on coagulation function. Methods Retrospective analysis of 95 cases hip fractures patients with clinical data, according to the preventive medication of DVT were divided into LMWH group of 42 cases and LMWH joint pressure pump group of 53 cases. The incidence rate of DVT and the degree of limb swelling after operation in two groups were observed. The differences of blood coagulation function indexes, blood rheology and hip function recovery were compared between the two groups. Results The the incidence rate of DVT in combination group was 1.89% (1 cases ), lower than LMWH group of 14.29% (6 cases )(χ2=5.278,P=0.022). After two weeks' treatment, the difference of anterior thigh circumference and calf circumference in combination group was less than LMWH group (P<0.05). The prothrombin time (PT) and activated partial thromboplastin time (APTT) in two groups post-treatment were lower than those pre-treatment, the D-dimer (D-D) was higher than that pre-treatment(P<0.05), but there was no significant difference between two groups. After 3 months' treatment, the Harris functional independence measure (FIM) in combination group was higher than that in LMWH group (P<0.05). Conclusion LMWH combined with pressure pump could significantly reduce the incidence of perioperative DVT in patients with hip fracture, improve the blood coagulation function and hip function.

Objective To evaluate the effects of acitretin combined with clarithromycin on tumor growth in human oral epidermoid carcinoma xenografts in nude mice,and to investigate their antitumor mechanisms.Methods A cell line of human oral epidermoid carcinoma was subcutaneously inoculated into 31 Balb/c nude mice to establish a xenograft model of human skin tumor.Then,the nude mice were randomly classified into 6 groups according to a double blind protocol:control group (n =6) remaining untreated,placebo group (n =5) treated with wheat flour,acitretin group (n =5) treated with acitretin 7.2 mg/kg per day,clarithromycin group (n =5) treated with clarithromycin 100 mg/kg per day,acitretin + placebo group (n =5) treated with both acitretin (7.2 mg/kg per day) and wheat flour,and acitretin + clarithromycin group (n =5) treated with acitretin (7.2 mg/kg per day) and clarithromycin 100 mg/kg per day.All the drugs were intragastrically administrated once daily.After three weeks of treatment,mice were sacrificed and xenografts were removed.Then,the size and weight of xenografts were measured,and pathological analysis was conducted.Real time-PCR was performed to quantify the mRNA expressions of vascular endothelial growth factor (VEGF) and nuclear factor (NF)-κB,and immunohistochemistry was carried out to observe the expression of VEGF as well as to determine microvessel density (MVD) and Ki-67 proliferation index.By using the software SPSS 19.0,analysis of variance was performed for comparison of measurement data,and least significant difference (LSD) test for paired comparisons.Results Both the size and weight of xenografts in the acitretin + clarithromycin group were significantly lower than those in the other groups (all P ＜ 0.05).Real-time fluorescence-based PCR revealed weaker mRNA expressions of VEGF and NF-κB in the acitretin + clarithromycin group compared with the control group,clarithromycin group and acitretin group (all P ＜ 0.05).As immunohistochemistry showed,the acitretin + clarithromycin group displayed a decrease in the expression rate (all P ＜ 0.01) and staining intensity of VEGF,MVD (all P ＜ 0.01) with a sparse distribution of microvessels,Ki-67 proliferation index (all P ＜ 0.05) and proliferative activity of tumor cells compared with the control group,clarithromycin group and acitretin group.Conclusion Acitretin combined with clarithromycin can synergistically inhibit the growth of human oral epidermoid carcinoma xenografts in nude mice,downregulate VEGF expression,and suppress angiogenesis and tumor proliferation.

Objective To investigate the association with death for serum parameters at the time of diagnosis and its value in predicting the death in infants with hemophagocytic syndrome (HPS).Methods A retrospective case-control study was conducted on 108 children with HPS who were admitted to our center between July 2005 and July 2012.For each patient,demographic,laboratory data and outcome information were collected.The patients were divided into death and surviving groups based on the follow-up results.The relation between serum markers and death was examined using the COX proportional hazards model and decision tree.Results Of 108 infants with HPS,33 died corresponding to a fatality rate of 30.6％ and 90.3％ of deaths occurred within 8 weeks after diagnosis.Following features were significantly associated with death:white blood cells (WBC) ＜5 x 109/L (HR =9.08,95％ CI 3.07 ～ 26.87),hemoglobin ＜80 g/L (HR =6.15,95％ CI 1.68 ～ 22.49),albumin ＜ 28 g/L (HR =4.63,95％ CI 1.12 ～ 7.39),serum ferritin ＞ 1 100 μg/L (HR =3.05,95％ CI 1.28 ～ 16.75),trigeminal ganglion ≥4 mmol/L (HR =2.88,95％ CI 1.51 ～ 8.60),and prothromin time ≥ 16 s (HR =3.60,95 ％ CI 1.28 ～ 7.24),and fever for more than 2 weeks (HR =5.39,95％ CI 1.97 ～ 14.66).Decision tree demonstrated that the probability of death was as high as 100％ for infants with WBC ＜5 x 109/L and hemoglobin ＜ 80 g/L.The odds of dying was still 66.7％ for infants who had WBC≥5 × 109/L but reported trigeminal ganglion ≥4 mmol/L after having fever for more than 2 weeks.Conclusion The first 8 weeks after the onset of HPS is the critical period of treatment.There are several easily available serum predictors of early mortality in HPS infants,particularly the WBC and hemoglobin level,which may help guide treatment decisions.

Objective To investigate the clinical value of three dimensional dynamic contrast enhanced MRA(3D DCE MRA)on esophageal and gastric varices compared with endoscopy.Methods From April 2003 to June 2008,153 patients with portal hypertension who underwent both 3D DCE MRA and endoscopy were reviewed retrospectively.All the patients were divided into bleeding group and non-bleeding group according to the clinical symptoms.The location and degree of the esophagogastric varices on 3D DCE MRA were assessed with postprocessing images,including subtraction,MIP and thin-slab maximum intensity projection(thin-MIP),and were compared with the results of endoscopy.The maximum,minimum and mean diameters of esophagogastric varices inside and outside of the wall were measured on the reformed images.The correlation between the findings of 3D DCE MRA and endoscopy were analyzed with Spearman rank correlation coefficient test The rates of esophagogastric varices outside of the wall in bleeding and non-bleeding group were compared by means of Chi-square test Results In bleeding group,severe esophageal varices were documented in 59 patients,moderate in 6 patients,mild in 5 patients;in non-bleeding group,severe esophageal varices were documented in 32 patients,moderate in 4 patients,mild in 5 patients.Severe,moderate,and mild gastric varices were documented in 28,34 and 16 in bleeding group,while they were 7,12 and 9 in non-bleeding group.Esophageal and gastric varices can be wholly presented on MIP images after subtraction,while the esophagogastric varices inside and outside of the wall can be differentiated on thin-MIP images.The location and degree of esophagogastric varices on 3D DCE MRA were correlated with the findings of the endoscopy.The range of r was from 0.544 to 0.878(P＜0.01).In 91 patients with severe esophageal varices,27 patients presented outside esophageal varices in bleeding group(n=59)and 24 patients presented outside esophageal varices in non-bleeding group(n=32).There was a significant difference in ratio of outside esophageal varices between bleeding group and nonbleeding group(X~2=7.199,P＜0.01).In 35 patients with severe gastric varices,22 patients showed adventitial gastric varices in bleeding group(n=28)and 4 patients showed adventitial gastric varices in non-bleeding group(n=7).The ratio of adventitial gastric varices in bleeding group was not significantly different from that of non-bleeding group(P=0.340).Conclusions 3D DCE MRA can display and differentiate the esophagogastric varices both inside and outside of the wall by three dimensional reconstruction.The results of 3D DCE MRA and endoscopy have good correlation.It is of importance in evaluating the esophageal varices outside of the wall,because they may indicate decreased risk of haemorrhage in patients with severe degree of esophageal varices.
