Objective To investigate the clinic diagnosis value of CT scan and the determination of serum NSE, Cyfra21-1 for SCLC. Methods ① The CT findings and pathologic basis of 220 cases with SCLC were analyzed retrospectively.② Between February 2000 and December 2001, 120 consecutive patients with pulmonary lesions by CT scan, which suspiciously suffered lung cancer, were studied prospectively. Serum samples were obtained by venous puncture from all patients 1 week prior to surgery or puncture biopsy. The serum concentration of NSE, Cyfra21-1 were determinated using ELISA. According to the pathologic result, the diagnostic value of CT scan, NSE and Cyfra21-1 were evaluated.Results ① Most CT findings of SCLC were central and spindly or eggplant-shape mass, hilar and/or mediastinal lymph nodes enlargement.The obstructive pulmonary lesions were found rarely.② Using CT scan, NSE and Cyfra21-1 alone, the sensitivity were 75%,72.5% and 32.5%,the specificity were 73.75%, 83.75% and 48.75%,the accuracy were 74.16%, 81.67% and 43.33% respectively. With combination of CT scan and NSE, the diagnostic accuracy was 78.3%, and the sensitivity was 87.5%. However, CT scan combined with Cyfra21-1 can not be improve the diagnostic value. Conclusion SCLC has specific CT findings. The sensitivity of CT scan was 75%, combinated with NSE, its accuracy was higher(78.3%), and the sensitivity was 87.5%.

It is very difficult for stroke patients to complete the action of squatting-standing because their equilibrium function ability has been seriously declined. It was necessary, therefore, to do a deep research on the action of human squatting-standing and to set up an accurate model and simulation. In our modeling research, the movements of upper limbs and head was neglected, and a seven-segment model was developed to establish the coordinate system of human squatting-standing action. It calculated the knee joint moment and hip joint moment during squatting and standing by utilizing Lagrange method, and then simulated this mathematical model by utilizing Matlab. Geometric model of human squatting-standing was developed and simulated in ADAMS which proved that the established Lagrange model was reasonable. It would also provide significant theoretical references for further study and development of squatting-standing rehabilitation training equipment.

4.Naringin reduced polymethylmethacrylate-induced osteolysis in the mouse air sacs model.
China Journal of Orthopaedics and Traumatology 2015;28(4):345-349
OBJECTIVETo evaluate the influence of naringin on PMMA-induced osteoclastic bone resorption using the mouse air sacs model.
METHODSTotal 48 female Balb/c mices with the age of 8 to 10 weeks were chosen in the study. Air were injected into the back in 32 mices and formed the air sacs, 6 d later, the skulls (originated from other 16 mices) were implanted to the air sacs. Thirty-two animals were divided into naringin treatment group (with 2 concentrations of 150 mg/kg and 30 mg/ kg) , DMSO group and PBS blank group, 8 animals in each group. Polymethylmethacrylate (PMMA) particles were injected into the air sacs in naringin treatment groups and DMSO group so as to irritate inflammatory reaction. Naringin with 2 concentrations of 150 mg/kg and 30 mg/kg were dissolved in DMSO of 0.2 ml, and were injected into air sacs, respectively. In PBS black group, no stimulation with PMMA particles, only injected PBS, and in DMSO group, injected DMSO without naringin. Tartrate resistant acid phosphatase (TRAP), Ca2+ release, modified Masson stain and histological analysis were performed on the 7th day after stimulation.
RESULTSCompared with DMSO group, naringin treatment group's cellular infiltration decreased (P < 0.01); concentration of 150 mg/kg was better than that of concentrations of 30 mg/kg (8.90 ± 1.75 vs 15.23 ± 1.86). Naringin can decrease calcium release in the lavage of the air sacs bone resorption model, especially obvious in naringin with concentration of 150 mg/kg. Naringin can ameliorate the inflammatory reaction and the subsequent bone resorption (including bone collagen loss, TRAP positive cells amount and so on) in air sacs with bone implant and PMMA particles. Naringin with concentration of 150 mg/kg appeared to be an optimal dosage to deliver the therapeutic effects.
CONCLUSIONNaringin inhibits PMMA-induced osteoclastogenesis and ameliorates the PMMA-associated inflammatory reaction and the subsequent bone resorption.

Objective: To determine whether paroxetine would be effective in the treatment of patients with chronic insomnia and to compare efficacy of paroxetine and estazolam on chronic insomnia. Methods: 74 patients with chronic insomnia were divided into 2 groups, receiving treatments of paroxetine and estazolam respectively. All of the subjects were assessed with Pittsburgh Sleep Quality Index (PSQI) and sleep diary. Results: 1. On the eighth day of treatment, estazolam group showed improvement, all the indexes of sleep were better than those before treatment and those of paroxetine group; 2. On the fifteenth day of treatment, paroxetine group showed improvement, all the indexes of sleep were better than those before treatment and those of estazolam group, while the indexes of the estazolam group returned to pre-treatment level. 3. At the end of treatments and 3 months' follow up, paroxetine group still showed better effect in sleep indexes than estazolam group and the pre-treatment level. Conclusion: paroxetine is effective in the treatment of chronic insomnia and shows long-term effect.

Objective To observe the influence of ulinastatin (UTI) on curative effect,inflammatory response and cellular immune function in patients with acute respiratory distress syndrome (ARDS).Methods 96 patients with ARDS were randomly divided into two groups:the control group (48 cases) were treated with conventional treatment,and the UTI group (48 cases) were added with UTI injection based on the control group treatment.The changes of oxygenation index,vital signs,inflammatory factors and T lymphocyte subsets of patients in the two groups were compared before treatment and after treatment in 7 days,recorded the duration of mechanical ventilation time,ICU treatment time and mortality rate in ICU in the two groups.Results After treatment in 7 days,the vital signs (RF,HR,MAP),inflammatory factors (TNF-α,IL-6,IL-8,PCT,CRP,WBC),liver function (AST,ALT),renal function (BUN,Cr) and APACHE Ⅱ score,MODS score of UTI patients in the UTI group were lower than those in the control group (P < 0.05 or P < 0.01).Oxygenation index (PaO2/FiO2) and cellular immunity (CD4+,CD4+/CD8+) in the UTI group were higher than those in the control group (P < 0.01).Mechanical ventilation time,ICU treatment time in the UTI group were shorter than those in the control group (all P < 0.05),the mortality rate of ICU in the UTI group was lower than that in the control group (P < 0.05).There was no significant difference in the incidence of adverse reactions between the two groups (P > 0.05).Conclusions UTI can more effectively improve oxygen metabolism,vital signs for ARDS,liver and kidney function,reduce the APACHE Ⅱ score and MODS score,shorten the mechanical ventilation time and ICU treatment time,reduce the mortality rate of ICU.Its mechanism may relate to clearance of inflammatory factors and regulate cellular immune function of UTI.
