In this study, we selected 24 crewmen who worked in the high temperature circumstances in the engine cabin, resulting in a great loss of body water, together with a large amount of inorganic salts and nitrogen. We Proved that the loss of sodium, potassium, and calcium in sweat is greater than that in urine. The excretion of sodium is the highest, then potassium, the lowest is calcium. The body weight of the engine member has a prominent decrease after summer. It seems that the regaining of body weight can be promoted by great supply of vitamins. So, we should give a large amount of proteins, vitamins and calcium to the members who worked in the circumstance of such a high temperature. The amount of salt is already quite enough in an ordinary meal.

Objective To study the clinical and electrophysiological features of the patients with hereditary neuropathy with liability to pressure palsy ( HNPP) diagnosed by gene analysis.Methods Seven patients from two HNPP families were assessed on medical history, physical examination, electrophysiology findings and gene analysis.Results A clinical manifestation of acute, painless, recurrent peripheral nerve palsies was typical for HNPP.Median, ulnar and peroneal nerves were usually affected.Electrophysiology study revealed that prolonged distal motor latency and slowing nerve conduction velocity were prominent.Gene studies exhibited a deletion of the peripheral myelination protein 22 gene in all the seven patients.Conclusions HNPP usually affects areas where nerves are subject to entrapment, and many episodes are preceded by minor compression on the affected nerve.As a reliable screening tool in detecting HNPP, the electrophysiological study shows that segmental demyelination is most commonly seen at common nerve entrapment sites.

Objective To measure the femoral head-neck ratio among Chinese adults in Nanjing to explore its clinical significance. Methods 468 Chinese without hip symptoms were chosen randomly. There were 313 males and 155 females. 13 cases were less than 20 years old, 88 cases were from 21 to 30 years old, 123 cases were from 31 to 40 years old, 104 cases were from 41 to 50 years old, 102 cases were from 51 to 60 years old, 24 cases were from 61 to 70 years old, 14 cases were more than 71 years old. The mean age was 42.4 years old (ranged from 17 to 82 years old). The maximum diameter of the femoral head and the minimum vertical diameter of femoral neck length on both sides were measured by Digimizer software in the standard anteroposterior pelvis film. The femoral head-neck ratio (FHNR) was calculated and compared with that of the western. Results The normal FHNR of Chinese in Nanjing was 1.48 ± 0.09 (1.33-1.69). FHNR was 1.46±0.09 in Chinese aged less than 20 years old. It was 1.48±0.09 in Chinese aged from 21 to 30 years, and 1.47±0.10 in those aged 31-40 years, 1.46±0.09 in 41-50 years, 1.49±0.10 in 51-60 years,1.48±0.08 in 61-70 years, 1.49±0.10 in those more than 71 years. There was no difference between male and female, the left and right side or the different age groups. There was no difference between the western and Chinese in Nanjing. Conclusion FHNR measurement has not variation with regard to sex, age and side. It may be useful to understand some kind of the hip diseases.

Synchronous multiple primary carcinomas refers to 2 or more than 2 kinds of different primary malignant tumors develop synchronously or in 6 months.The incidence of synchronous multiple primary carcinoma is low.A patient with esophageal basaloid squamous cell carcinoma (BSCC) and gastric adenocarcinoma was admitted to the First People's Hospital of Lianyungang in October 2011.The main symptom of this patient was dysphagia,and multiple lesions were found in esophagus,cardia and stomach fundus by gastroscopy respectively.On computed tomography image,eminence lesion in esophageal midpiece and wall thickening from esophagus-cardia to stomach fundus were displayed and were both enhanced slightly by enhancement scanning.The esophageal and cardia tumors were resected via left thoracic approach,and postoperative pathological examination revealed esophageal BSCC and moderately differentiated adenocarcinoma of cardia respectively.Comedo necrosis and red basal membrane material were seen under light microscope.The expressions of cytokeratin 5/6 and P63 were positive,the expression of cytokeratin L was weak positive and the expressions of synaptophysin,chromogranin A and CD117 were negative.The patient suffered from pleural effusion and multiple liver metastases after 4 months follow-up and died of liver metastases in May 2012.Multiple primary carcinomas including esophageal BSCC and gastric adenocarcinoma are rarely seen in clinical practice.Their diagnosis and differential diagnosis mainly depend on histological morphology and immunohistochemical method.Surgical resection combined with postoperative radiotherapy and chemotherapy is selectable,but the prognosis is poor.

Methods A total of 72 MHD patients from two hospitals in Shanghai were enrolled in a randomized parallel controlled study.Conventional hemodialysis was performed for 4 h with PES14LF dialyzer in trial group and with German F6 dialyzer in control group.For each patient the study lasted one week.The clearances of urea,creatinine and phosphate were calculated.Adverse event and adverse reaction were recorded.Results There were no significant difierences of urea and creatinine clearance and reduction ratio between trial and control group.The phosphate clearance in trial group was significantly higher than that in control group[(144.57±27.83)ml/min vs(117.15±22.77)ml/min,P＜0.051.There was no significant difference of phosphate reduction ratio between trial and control group.The efficiency of urea clearance and urea reduction ratio achieved clinic effective target in two groups and no significant differences in above indexes between two groups were found. Conclusion PES14LF dialyzer is effective and safe for clinical application.

Objective To evaluate the nutritional status in maintenance hemodialysis patients using objective score of nutrition on dialysis.Methods Patients on maintenance hemodialysis were randomly selected and divided into three groups based on objective score of nutrition on dialysis:normal nutritional status group,moderate nutritional status group,and low nutritional status group.Logistic regression analysis was performed to identify factors of malnutrition.Furthermore,the results were compared with those of subjective global assessment.Results Totally 75 patients(male:female =1.13∶1)with a mean age of(54.90 ± 12.10)years and a mean vintage of (85.37 ± 54.17)months were enrolled.As determined by objective score of nutrition on dialysis,15 patients (20％)were divided into normal nutritional status group,42(56％)into moderate nutritional status group,and 18(24％)into low nutritional status group.Compared with the normal nutritional status group,the low nutritional status group had significantly different body mass index[(19.81 ± 2.22)vs(23.90 ± 2.44)kg/m2,P =0.030]and dry weight[(50.85 ± 7.60)vs(59.94 ± 10.89)kg,P =0.020].In addition,compared with normal nutritional status group,the moderate nutritional status group and low nutritional status group had significantly different total cholesterol[(4.60 ± 0.84)and(3.73 ± 0.68)mmol/L vs(5.71 ± 1.64)mmol/L,P =0.011,P =0.000],normalized protein catabolic rate[1.17 and 1.15 g/(kg · d)vs 1.45 g/(kg · d),P =0.030,P =0.010],triceps skinfold thickness[(1.44±0.77)and(1.00±0.41)cmvs(1.80±0.63)cm,P=0.032,P=0.020],mid-ann circumference[(24.85±1.48)and(21.66±1.48)cmvs(24.99 ±2.30)cm,P=0.046,P =0.037].Logistic regression analysis indicated C-reactive protein(OR =12.482,95％ CI =0.190-130.928,P =0.035)and normalized protein catabolic rate(OR =0.128,95％ CI =0.022-0.736,P =0.021)were significantly correlated with malnutrition.Conclusion Malnutrition is common in hemodialysis patients,with inflammation and low protein intake being its independent factors.

Objective To observe the effects of electroacupuncture combined with edaravone on the conduction velocity of sciatic nerve and oxidative stress in rats with diabetic peripheral neuropathy. Methods 60 Sprague Dawley (SD) rats were included. 10 of them were selected as normal group. The other rats were modeled as diabetic peripheral neuropathy with streptozotocin. 48 of them were randomly selected and divided into electroacupuncture group (n=12), edaravone group (n=12), electroacupuncture + edaravone group (n=12), and model group (n=12). The threshold temperature for wave tail was tested, the levels of superoxidase dismutase (SOD) and malonaldehyde (MDA) were determined, and the conduction velocity of sciatic nerve were measured, before, and 4 and 8 weeks after modeling. Results 8 weeks after modeling, the conduction velocity and SOD increased in the electroacupuncture group, edaravone group and electroacupuncture+edaravone group compared with the model group (P<0.01), with the MDA decrease (P<0.01), while it was improved more in the electroacupuncture+edaravone group than in the electroacupuncture group or the edaravone group (P<0.01). Conclusion Both electroacupuncture and edaravone can inhibit oxidative stress and improve nerve conduction velocity of the sciatic nerve in rats with diabetic peripheral neuropathy, and it is more effective of combination.

OBJECTIVETo explore the influence of lanthanum chloride on the TNFalpha expression of murine peritoneal macrophages stimulated by lipopolysaccharide (LPS).

METHODSMurine peritoneal macrophages (Mphi) were isolated, cultured and then stimulated by LPS. The influence of lanthanum chloride on the TNFalpha secretion and TNFalphamRNA expression of murine Mphi stimulated by LPS was determined by ELISA method and SYBR green fluorescence quantitative RT-PCR. Forty BALB/C mice were randomly divided into two groups and were treated by lethal dose of LPS and lanthanum chloride processed LPS, respectively. The mortality within 7 days was observed.

RESULTSThe TNFalpha secretion and TNFalphamRNA expression level of the Mphi from mice treated by lanthanum chloride processed LPS were obviously lower than those by LPS only (P < 0.01). The mortality of the mice treated by lethal dose of LPS which has been processed by lanthanum chloride was significantly lower than that by lethal dose of LPS only.

CONCLUSIONLanthanum chloride possessed the capacity of lowering down the toxicity of LPS and inhibiting the TNFalpha secretion and TNFalphamRNA expression in murine Mphi stimulated by LPS.
