One hundred seventy of patients with cervical esophageal carcinoma (30 cases were treated by pre-operative radiation and surgery (combined group), 27 cases by surgery alone, 113 cases by radical radiation). The doses of the preoperative radiation and the radiacal radiation were D T40 Gy/4w and above D T 50 Gy/5w, respectively. The 5 year survival rates were 40% in the combined group, 15.3% in surgry alone, and 28% in radical radiation groups. The difference of survival rates in the combined group and surgery alone was significantly different statistically. Factors affecting the survivals were lymphnode metastasis in radical radiation and recurrent larygeal nerve paralysis in the combined group. The main causes of failure were local residual and recurrence (71%) in radical radiation and lymphnode metastasis (81%) in the combined group. The authors believe that pre-operative radiation combined with surgery could improve the survival of cervical esophageal carcinoma. Radical radiation is also one of effective treatment methods for cercical esophageal carcinoma.

A prospective clinical trial was carried out to explore the hemostatic effect of Gongxueting Mixture on metrorrhagia and metrostaxis with blood stasis syndrome and its mechanism. Bleeding time and bleeding volume in 37 cases were detected before and after treatment to assay the hemostatic effect. Indexes of blood analysis, blood rheology, blood coagulation and prostaglandin in 8 cases were determined to study the mechanism. The results showed that Gongxueting Mixture shortened the menstrual period and regulated the volume of menses (P 0.05 ). It is concluded that Gongxueting Mixture is effective for metrorrhagia and metrostaxis with blood stasis syndrome (the total effective rate being 91.89% ), and enhancement of platelet aggregation, promotion of fibrinolytic activity and regulation of prostaglandin release may be its hemostatic mechanism.

Objective To study the clinical significance of the injury and functional change of hypothalamic-pituitary-adrenal (HPA) axis after acute severe traumatic brain injury (TBI) in the rats.Methods A total of 60 adult healthy male Spraque-Dawley rats were randomly (random number) divided into 3 groups (n =20 in each group):sham operation group,model group and treatment group.The TBI models of rats were established by Feeney' s method.A low dose of dexamethasone (0.6 mg/kg) was injected into the abdominal cavity 20 minutes,24 hours and 48 hours after injury in treatment group,while rats of sham operation group and model group received equal volume of normal saline instead.All the rats were injected 1 μg adrenocorticotropic hormone (ACTH) into the abdominal cavity.The related parameters were detected at four time points,3 hours,12 hours,24 hours and 72 hours after cerebral contusion.The plasma corticosterone (CORT) and ACTH levels were measured by chemiluminescence.The hypothalamic,pituitary and adrenal of the rats were taken out for observing interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) expression detecting by immunohistochemical techniques at 72nd hour after TBI.One-way ANOVA and SNK-q test were used to analyze the results with SPSS 17.0 software package.Results The levels of ACTH and CORT on 3rd hour of model group raised remarkably compared with that of sham operation group,then they reduced gradually.The levels of CORT were lower than that of sham operation group at every time points after ACTH stimulation test (P <0.05 or P <0.01).The levels of CORT at all time points of treatment group were changed remarkably compared with that of model group.However,the ACTH levels of treatment group on 24 h increased slightly than that of model group.And the tendency of them was similar to model group (P < 0.05 or P < 0.01).The number of the hypothalamus and pituitary cells which express IL-6 and TNF-α in model group was more significantly increased when compared with that in sham operation group (P < 0.01),while the number of this kind of cell in treatment group was significantly decreased than that in model group (P < 0.01).The number of the adrenal cortex cells which express IL-6 in treatment group was more significantly decreased when compared with that in model group (P< 0.01),while the number of this kind of cell in model group was significantly increased than that in sham operation group (P < 0.01).However,there was no significant difference of the TNF-α between all the groups (P > 0.05).Conclusions Functional change of adrenal occurs early in the severe acute traumatic brain injury rats,and the response of adrenal to ACTH decreased as time goes by.Low-dose,short-course dexamethasone can delay the pathological changes,reduce the inflammatory response of HPA axis and increase the sensitivity of adrenal response to ACTH.

OBJECTIVETo investigate the variation in movement traces of different condylar reference points.
METHODSIn 30 healthy subjects, mandibular movements were recorded during protrusion and open-closing of the jaw. The kinematic center and terminal hinge axis point of the condyle were used as reference points.
RESULTSThe kinematic center was located anteriorly and superiorly with respect to the terminal hinge axis point. The trace distance of the kinematic center was longer than that of the terminal hinge axis point of the condyle during opening. In contrast to differences in trace distances of the left and right condylar terminal hinge axis points, no such left-right differences were found for the kinematic centers. The ratio between the distance of opening trace and the distance of protrusion trace of the kinematic center was above 1.5.
CONCLUSIONSIn comparison to the terminal hinge axis, the kinematic center shows fewer variations in the movement traces.

Burn rehabilitation in China started from compression therapy in the mid-1970s, which showed the dual effects of prevention and treatment of hypertrophic scars. It not only promoted functional rehabilitation but also strengthened the confidence of patients in rehabilitation treatment. Thereafter, more therapies were brought into practice, such as intra-scar injection of triamcinolone acetonide, application of plastic splints, hydrotherapy, exercises with equipment, skin care, local therapeutic massage, active and passive exercises, as well as external use of drugs for inhibiting scars and pigments. Since the beginning of the 21st century, rehabilitation therapies have been gradually increasing. Psychological rehabilitation, occupational therapy, external use of silicone gel, wax therapy and sound, light, electricity, and radiation therapy have been carried out. Many hospitals have established foundations and held summer camps for children. As far as the whole country is concerned, compared with the huge demand, we still face a number of problems such as shortage of working staff, limited working space, capital chain rupture, lack of multi-disciplinary cooperation, untimely treatment, and incomplete rehabilitation. Nowadays, with increasing knowledge of burn rehabilitation and number of practitioners, improvement of equipment and economic situation, the pace of rehabilitation has accelerated, and the overall implementation of burn rehabilitation therapy has shown great vitality. Patients with burn injury involving over 80% total burn surface area (TBSA) of total burn area or full-thickness burn over 60% TBSA were cured and recovered in different levels of hospitals nationwide, which not only reflects the superb level of burn treatment in China but also reflects the overall improvement of rehabilitation level of the country.

Objective To investigate the relationship between body composition and adequacy of dialysis,and analyze the related risk factors for inadequate delivery of hemodialysis.Methods In a prospective clinical trial,two different methods determining dialysis dose were simultaneously applied:Kt/Vdau (conventional method with Daugirdas' formula) and Kt/Vbem [online clearance monitoring (OCM) measurement with Ⅴ measured by body composition monitor (BCM)].Using the value of 1.27 as the boundary,the patients were divided into two groups:Kt/Vbcm < 1.27 group and Kt/Vbcm≥ 1.27 group.Clinical indices were compared between the two groups.Multiple linear regression was applied to analyze the potential impact factors of the difference between Kt/V values calculated by the two methods.Receiver operator characteristic (ROC) curve was applied to analyze meaningful factors.Results A total of 138 maintenance hemodialysis patients with age of (54.9±12.7) years old were enrolled,and 55.1% of them were males.There was no significant difference between Kt/Vdau and Kt/Vbcm [1.432(1.235,1.718) vs 1.434 (1.244,1.642),P=0.823].Kt/Vdau was incidentally prone to falsely high values due to operative errors,whereas in these cases OCM-based measurement Kt/Vbcm delivered realistic values.An excellent correlation was observed between Kt/Vdau and Kt/Vbcm;the mean difference was 0.07,95%CI (-0.66-0.79);the correlation coefficient was 0.842(0.821-0.862).The patients in Kt/Vbcm≥ 1.27 group had older age,lower body mass index (BMI),lower height and weight,lower total body water (TBW),lower extracellular water,lower intracellular water,and lower lean tissue index (LTI) compared to those in Kt/Vbcm < 1.27 group.Excellent correlations were observed between Kt/Vbcm and TBW or LTI (r=-0.834,P < 0.001;r=-0.721,P < 0.001).ROC curve analysis showed that the sensitivity and specificity of predicting inadequate delivery of hemodialysis were 87.1% and 86.5%,with a threshold of 30 L for TBW.It also showed that the sensitivity and specificity of predicting inadequate delivery of hemodialysis were 60.4% and 94.6%,with a threshold of 11.05 kg/m2 for LTI.Conclusions BCM can give more accurate parameters of urea distribution volume,thus modifying the result of Kt/V.TBW and LTI are important risk influencing factors for inadequately dialysis,and special attention should be paid to patients with TBW > 30 L or LTI > 11.05 kg/m2.
