Objective To compare the clinical efficacy of traditional excision of involved lymph nodes and functional neck dissection in the treatment of patients with multiple cervical tuberculous lymphadenopathy(MCTLP).Methods From Jan 2006 to May 2008,76 patients with MCTLP who presented with focal liquefaction or sinus formation after ineffective conservative therapy were randomly divided into study group(functional neck dissection) and control group.Data regarding the 3-month recurrence rate,postoperative neck function,the mean hospitalization days and medical costs of the 2 groups were compared.Results There was significant difference in relapse rate 3 months postoperatively between study group(1 case,2.56%) and control group(7 cases,16.22%)(

Objective To analyze the changes of the urine sodium and serum sodium in different types and different duration and different temperature in children with febrile seizures,to explore its clinical significance. Methods The children with febrile seizures(n =50)were selected as the group Ⅰ,and the children with fever but without seizure(n =50)were selected as the group Ⅱ,both of them were from pediatric ward.The control group(n =20)without fever or seizure was from Children's Health Section.All the children were checked serum sodium level and urine sodium and urine creatinine level.Results The sodium/creatinine ratio in the groupⅠ[(25.07 ±6.517)] was significantly higher than that in the group Ⅱ[(20.43 ±5.48)]and group Ⅲ[(14.88 ±5.11)](F =33.519, P <0.05),but there was no significant difference of the sodium/creatinine ratio in different ages and different types of the group Ⅰ,and there was negative relevance between the serum sodium and the sodium/creatinine ratio in the groupⅠ(r =-0.517,P <0.05).The mean serum sodium level in the groupⅠ[(133.50 ±3.14)mmol/L]was signifi-cantly lower than that in the group Ⅱ[(137.60 ±2.59)mmol/L]and group Ⅲ[(138.90 ±2.24)mmol/L](F =39.220,P <0.05),but there were no significant differences of the serum sodium in different types and different dura-tion and different temperature of seizure in the group Ⅰ.Conclusion The study shows that serum sodium is lower and the urine sodium is higher in children with febrile seizures,the changes of the urine sodium and serum sodium are not related to the types.The children with febrile seizures should be timely monitoring of serum sodium,urine sodium levels,and according to changes in the level of serum sodium,urine sodium,early appropriate supplement containing sodium liquid and maintaining the blood sodium to normal levels can reduce the recurrence of seizure.

The study included 24 patients of lung cancer with bone metastasis, 26 patients of lung cancer without bone metastasis and 27 healthy controls. The serum levels of β-crosslaps of type Ⅰ collagen (β-CTX), M-MID and urinary β-CTX/creatinine (CTX/CR) were measured by ELISA. Results showed that the serum levels of β-CTX and urinary CTX/CR in lung cancer patients with bone metastasis were significantly higher than those without bone metastasis (P ＜ 0. 01 ). The findings suggest that the measurement of serum β-CTX and urinary CTX/CR may indicate bone metastasis in lung cancer.

Objective To observe the effects of vitamin K3(VK3) on cell growth and apoptosis in the cell line SMMC-7721 of human liver cancer and the changes in expression of survivin gene.Methods The inhibitory effect of VK3 on SMMC-7721 cells was examined by CCK-8 (cell counting kit).Morphological evaluation of apoptosis was performed by Hoechst33342 staining.The amount of apoptotic cell was assayed by flowcytometry.The changes of survivin gene expression were detected by RT-PCR.Results The inhibitory rate of VK3 (at concentrations of 2,5,10,20,25 mmol/L for 48 h) on SMMC-7721 growth was 3.8%,50.1%,63.9%,78.5%,84.7% respectively.The cells in apoptosis were strongly stained by Hoechst33342 compared with the cells in control group.The apoptostic rate of cells was 33.28%,63.97%,77.69%,87.30% and 92.40%.Following exposure to VK3 at the concentration of 2,5,10,20 and 25 mmol/L for 48h,the survivin mRNA expression in SMMC-7721 was downregulated.Conclusion VK3 inhibits the proliferation of SMMC-7721 cells and induce apoptosis.The mechanism may related to survivn gene.

Objective To evaluate the efficacy and safety of caspofungin in the treatment of invasive fungal disease (IFD) in advanced age patients. Methods A retrospective analysis of the clinical data was conducted. IFD patients who had received caspofungin treatment in elderly wards were included. Results From January 2007 to August 2009, 29 IFD patients aged 80-100 years (mean 89 ) were treated with caspofungin. Except that one patient dead on the first drug administration day, there were 28 evaluable patients, 13 were cured (46.4%), 6 were markedly improved (21.4%), 3 progressed (10.8%) and 6 dead (21.4%). The overall effective rate was 67. 8%. Of 13cured patients, 12 were Candida bacreremia, 1 was Candida albicans disease of lung. Of 6 dead patients, 2 were Candida bacteremia, 1 was Candida albicans disease of lung and 3 was suspected of lung IFD. One patient performed that alanine aminotransferase was increased, considering drug-related impairment of liver function. Conclusions Caspofungin is effective and safe in the treatment of IFD in advanced age patients.

Objective To analyze the correlation of nonalcoholic fatty liver disease (NAFLD) with waist,hip circumference and body mass index in order to explore the prevention countermeasures.Methods The datum of routine physical examination and questionnaire survey among 2 503 employees of 12 enterprises in November 2013 were collected.The indexes of height,weight,waist circumference,hip circumference,blood pressure,blood lipid and blood glucose of the subjects were measured.The grouping was according to whether the subjects suffering from NAFLID.The correlation and epidemiological characteristics between each group and the risk factors of body weight,waist,hip circumference and body mass index were analyzed.Results 2 503 subjects were collected including 490 NAFLID patients (19.57％).The body weight and body mass index of NAFLID patients were significantly lower than those of the control group.The result of BMI classification showed that the subjects of the control group were overweight while the subjects with NAFLID were obesity.The waist circumference and hip circumference of NAFLID patients were significantly larger than that of the control group.Conclusions Larger waist and hip circumference and overweight are risk factors of NAFLID.Effective intervention measures,scientific control of body weight,rational diet,the strengthening of physical exercises should be taken in order to prevent and control the development of fatty liver.

Objective To investigate the features and prevention measures of complications secondary to severe traumatic hemorrhagic shock (THS) of different crowds in plateau (3 658 meters above the sea level).Methods A retrospective study was conducted on 591 severe THS patients undergone traditional resuscitation (traditional resuscitation group,n =103) from October 1976 to October 1990 and integrated treatment (integrated treatment group,n =488) from October 1991 to October 2012.The patients included native Tibetans,Han immigrants in plateau (≥ 3 months) and Han people who entered plateau rapidly (＜ 7 days).Outcome of the two treatments was compared.Results With regard to the traditional resuscitation group,native Tibetans sustained the main complications including stress ulcer (n =2),pulmonary edema (n =1),MODS (n =3) and death (n =3) ； Han immigrants in plateau sustained the main complications including stress ulcer (n =9),pulmonary edema (n =8),ARDS (n =3),cerebral edema (n =1),acute renal failure (n =3),disseminated intravascular coagulation (DIC) (n =2),MODS (n =13) and death (n =11)； Han people who entered plateau rapidly sustained the main complications including stress ulcer (n =5),pulmonary edema (n =4),ARDS (n =4),cerebral edema (n =2),acute renal failure (n =3),DIC (n =2),MODS (n =6) and death (n =4).Whereas in contrast to the relevant patient crowds in the traditional resuscitation group,the native Tibetans,Han immigrants in plateau and Han people who entered plateau rapidly presented significant reduction of complication rate and mortality rate in the integrated treatment group.Conclusions (1) Traditional resuscitation for severe THS patients in plateau results in much more complications with quick occurrence,high incidence,rapid progression,high severity and high mortality.Moreover,the complications are more severe in Han people who entered plateau rapidly than in the Han immigrants in plateau and native Tibetans.(2) The incidence of complications and death rate are significantly reduced after integrated treatment.(3) Han people who entered plateau rapidly present larger dependence on integrated treatment than the Han immigrants in plateau and native Tibetans.

The accuracy and repeatability of computer aided cervical vertebra landmarking (CACVL) were investigated in cephalogram. 120 adolescents (60 boys, 60 girls) aged from 9.1 to 17.2 years old were randomly selected. Twenty-seven landmarks from the second to fifth cervical vertebrae on the lateral cephalogram were identified. In this study, the system of CACVL was developed and used to identify and calculate the landmarks by fast marching method and parabolic curve fitting. The accuracy and repeatability in CACVL group were compared with those in two manual landmarking groups [orthodontic experts (OE) group and orthodontic novices (ON) group]. The results showed that, as for the accuracy, there was no significant difference between CACVL group and OE group no matter in x-axis or y-axis (P>0.05), but there was significant difference between CACVL group and ON group, as well as OE group and ON group in both axes (P<0.05). As for the repeatability, CACVL group was more reliable than OE group and ON group in both axes. It is concluded that CACVL has the same or higher accuracy, better repeatability and less workload than manual landmarking methods. It's reliable for cervical parameters identification on the lateral cephalogram and cervical vertebral maturation prediction in orthodontic practice and research.
