Objective To evaluate the efficacy of potassium sodium dehydroandroan drographolide succinate (PSDS) combined with routine therapy for rotavirus enteritis in children.MethodsA total of 148 children with rotavirus enteritis were included and divided into an observation group and a control group by random number table method, 74 in each group. The children in the observation group were treated with intravenous PSDS combined with routine therapy, and those in the control group with intravenous ribavirin combined with routine therapy. Serum interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were determined by enzyme-linked immunosorbent assay, and plasma lactate dehydrogenase (LDH), creatine kinase (CK), and creatine kinase-MB (CK-MB) were determined using standard clinical laboratory procedures. The clinical efficacy was evaluated. Results The total efficacy rate in the observation group was significantly higher than that in the control group (91.9%vs. 78.4%;χ2=2.314,P<0.05). After the treatment, the serum levels of IL-6 (18.24 ± 3.62 ng/mlvs. 25.36 ± 5.25 ng/ml; t=2.425,P<0.05) and TNF-α (20.86 ± 4.28 ng/mlvs. 31.22 ± 7.15 ng/ml;t=2.503,P<0.05), and the plasma levels of LDH (104.25 ± 22.06 U/Lvs. 150.26 ± 37.22 U/L;t=2.316,P<0.05), CK (84.25 ± 13.57 U/Lvs. 107.88 ± 16.28 U/L;t=2.327,P<0.05) and CK-MB (22.30 ± 4.24 U/Lvs. 32.26 ± 7.14 U/L;t=2.426,P<0.05) in the observation group was significantly lower than those in the control group. The time to diarrhea resolution (2.42 ± 0.53 dvs.3.56 ± 0.78 d;t=2.316,P<0.05) and the time to fever resolution(2.11 ± 0.32 dvs.2.63 ± 0.43 d;t=2.472,P<0.05) in the observation group were significantly delayed than those in the control group, and the hospital length of stay longer (6.23 ± 1.42 dvs. 4.35 ± 0.96 d;t=2.413,P<0.05).Conclusions PSDS combined with routine therapy may reduce inflammatory response, protect from myocardial injury, and promote recovery in children with RVE.

Recently,commercialized infant body plethysmography has been widely used in clinic and re-search,especially with the publication of recommendation for this equipment and methodology. As the most valu-able equipment in measuring airway resistance and lung volume,infant body plethysmography can show series of valuable data on lung function,which is important in assessing pulmonary growth and development,evaluating respiratory mechanics and helping diagnose disease. However,the application of infant body plethysmography in clinic and physiology measurements is still limited by the effectivity of this equipment and appropriate reference values. This review is to introduce body plethysmography in infants,describe frequently-used data of lung func-tion,and discuss its potential clinical significance and availability of reference values.

The automatic nervous system(ANS) has 2 main branches:the sympathetic nervous system and the parasympathetic nervous system.The ANS controls mainly automatic bodily functions that are engaged in homeostasis.Autonomic dysfunction lead to many diseases,for example,orthostatic intolerance etc.The relationship between vitamin D and cardiovascular disease has becomes the focus of study gradually in recent years.1,25-dihydroxy vitamin D participates in the regulation of renin-angiotensin axis,vascular effects.Vitamin D deficiency triggers secondary hyperparathyroidism,promotes the development of hypertension,diabetes,dyslipidemia which can influence the incidence and prognosis of cardiovascular disease as well.The study confirmed that vitamin D deficiency is one of the risk factors of cardiac autonomic dysfunction diseases such as orthostatic intolerance.The mechanism is still not very clear.Supplement of vitamin D can offer an effective method to decrease cardiovascular disease risk in populations with low vitamin D status.

Objective To investigate the therapeutic mechanisms for differentiated thyroid cancer by using CIK and IL-2, to find out the better adjunctive clinical therapies for thyroid cancer patients after operation, and to evaluate the effects of cytokine-induced kill cell (CIK) and IL-2 on the secretion of thyroxine by thyroid papillary carcinoma. Methods The samples of thyroid papillary carcinoma were taken from the excised tissues of patient with thyroid cancer, and then dispersed with collagenase and trypsin for culturing. The carcinoma cells were then seeded in 24-well cell culture plates at 37℃, 5% CO2 and 95% humidity for 3 days. At the fourth day, the cells in the wells were separately stimulated four times with different dosage of CIK and IL-2, and the stimulation lasted for 72 hours each time. 12 days later, the solution of T3, T4 was detected with radio-immunity kits, TSH was detected with immuno-radiation kits, and the cell proliferation was detected with mono-nuclear cell direct cytotoxicity assay. Results The thyroid cancer cells did not respond to IL-2 in median and low concentrations, but responded to IL-2 in a higher concentration which may depress the secretary function of thyroid cancer cells. IL-2 of high concentrations can obviously decrease the hormone secretion, such as Thyroxine and Thyrotropin, of papillary carcinoma, and improve the CIK's ability of killing cancer. CIK can kill the cancer cells only when companied with IL-2. Conclusion IL-2 of high concentrations can't inhibit the proliferation of thyroid cancer cells, but can depress the secretary function of thyroid cancer cells, which is different from the killing mechanism of CIK.

Objective To develop a willpower scale for Chinese civil pilots.Methods 695 civil aviation pilots were collected by stratified random sampling based method on different positions.Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to analyzed the data and tested the reliability and validity of scale.Results The scale consisted of 16 items and 4 dimensions (pressure resistance,self-control,insist and decisiveness).4 dimensions explained 59.978% of the total variance.The Cronbach's α coefficient of full scale was 0.800,and the Cronbach's α coefficient of each factors were from 0.715 to 0.783.Coefficient of stability of the scale was beyond 0.805 (P<0.01).The correlation coefficient among each dimensions were from 0.050 to 0.366 (P<0.01),and the coefficient between each dimensions and the total score were from 0.565 to 0.699(P<0.01) and criterion validity of the questionnaire was 0.655 (P<0.01).Confirmatory factor analysis showed that the fitting effect of the four factors model was optimal (GFI=0.909,IFI=0.948,TLI=0.934,CFI=0.946,RMSEA=0.054).Conclusion The scale meets the requirements of psychological surveying,and it can be used as an effective tool for willpower of Chinese civil pilots.

Objective To investigate outcomes of different surgical approaches for treating cases of fracture and dislocation of the lower cervical spine.Methods The study involved 26 cases of fracture and dislocation of the lower cervical spine treated surgically from December 2002 to January 2012,including 19 males and 7 females with age ranging from 27 to 62 years (average 39 years).According to the AO classification,there were 12 cases of type B3.1,three of type B3.2,two of type C2.1,three of type C3.1,and six of type C3.2.Preoperative spinal cord function graded by Frankel criteria was six cases of grade A,five of grade B,seven of grade C,six of grade D,and two of grade E.Conventional skull traction was done for all patients before operation.Vertebral cannal decompression and interbody fusion through anterior,posterior or anterior-posterior approaches were determined according to type of fracture dislocation and severity of spinal cord injury.Radiography was performed regularly after operation to review the correction of dislocation,restoration of vertebral height,and interbody fusion.Spinal cord function was also evaluated postoperatively.Results No large blood vessel injury or aggravation of spinal cord injury occurred intraoperatively.There were no complications of incision infection,leakage of cerebrospinal fluid,herniation of bone graft or implant breakage postoperatively.All cases obtained successful correction of fracture and dislocation of the lower cervical spine as well as the recovery of cervical sequence,physiological curvature,and vertebral height in the 12 to 24 months of follow-up (average 16 months).Bony fusion was obtained for all cases at postoperative 3-6 months (average 3.5 months).Spinal function evaluated by Frankel criteria at the latest follow-up showed was grade A in six cases,grade B in three,grade C in five,grade D in five and grade E in seven,with different degree of improvement for all cases.Conclusions Operative approaches should be selected according to the specific status of fracture and dislocation of the lower cervical spine.Anterior approach can be performed for vertebral or intervertebral disc injury straightly and the procedure handles cervical instability immediately.Posterior surgical approach can be used to settle dislocation and interlocking of the articular process directly,but the intervertebral disc injury should be ruled out simultaneously in order to avoid further injury of spinal cord during the reduction process.Combined anterior and posterior surgical approach can be applied to treat fracture and dislocation of lower cervical spine and intervertebral disc injury concurrently but has high risk and large operation wound.

Objective To explore the lowest and most effective dose of dezocine in preventing postoperative pain after painless artificial abortion.Methods A total of 180 ASA Ⅰ ～ Ⅱ patients who accepted painless artificial abortion were randomly divided into 6 groups (n =30 patients per group).Group 1 (control) was given the placebo (0.9％ NS; 2 ml) by vein while other groups were given dezocine by vein with 0.01 mg/kg (group 2),0.02 mg/kg (group 3),0.03 mg/kg (group 4),0.04 mg/kg (group 5),and 0.05 mg/kg (group 6),respectively.The dosage of propofol,BP,HR,SpO2 during the operation,operation time,consciousness recovery time,analgesic effect (VAS score),leaving time,defecation feeling,and untoward reaction of each group were recorded and compared.Results The dosage of propofol in the 5 dezocine groups were significantly lower than that in the control group,respectively (t =2.38,4.72,6.03,4.57,3.96,P ＜ 0.05),while the difference in the operation time,consciousness recovery time and leaving time between the 5 dezocine groups and the control group had not statistical significance (P ＞0.05).The effect of postoperative analgesia and defecation feeling were apparently improved in the group 3,4,5 and 6,compared to the control group(group 3:x2 =3.36,6.94,P ＜ 0.05;group 4:x2 =7.17,15.01,P ＜ 0.05 ; group 5:x2 =15.5,24.3,P ＜ 0.01 ; group 6:x2 =13.01,20.24,P ＜ 0.01).Conclusions The lowest and most effective dose of dezocine was 0.05 mg/kg in preventing postoperative pain after painless artificial abortion.

Major breakthrough and challenge that encountered by modern western medicine were described in this article. Some standpoints about the necessity of innovative revolution for the development of traditional Chinese medicine, together with the key points should be bring to the attention during ideological emancipation have been put forward here. Chinese scientists agreed that it is the most appropriate timing for us to establish a new medicine system, which we named Holistic Systems Medicine (HSM). The concept and research contents of Holistic Systems Medicine were also introduced in this article.

The objective of this study is to fully investigate the therapeutic effect and mechanisms of action of Gegen Qinlian decoction (GD) on type 2 diabetes mellitus (type 2 DM). A rat model of type 2 DM was established with the combination of high-fat diet and multiple low doses of streptozotocin (STZ). Biochemical indicators related to glucose metabolism disorders, insulin resistance, oxidative stress were observed. The type 2 DM rats were administrated with GD for 80 days, the above-mentioned indexes were detected. The results indicated that the hepatic glycogen synthesis level was promoted, fasting blood glucose level and fasting blood insulin level were significantly reduced, insulin sensitivity index was significantly improved; the level of superoxide dismutase (SOD) was increased and the level of malondialdehyde (MDA) was reduced; pathologic morphology of pancreas and kidney was ameliorated in the GD group. It was indicated that the therapeutic mechanisms of action of GD on type 2 DM might be related to its effect of ameliorating glucose metabolism disorders, relieving insulin resistance, increasing the tissues' sensitivity to insulin, improving the antioxidative ability of living system, GD has therapeutic effect on type 2 DM and protective effects against damaged pancreatic function.
