ObjectiveTo observe the characteristic of pulmonary function of children with spastic diplegia and the effects of hydrotherapy on it. Methods30 children with spastic diplegia were divided into hydrotherapy group and control group, who received hydrotherapy and routine rehabilitation or routine rehabilitation only. All patients were tested their pulmonary function and the maximum phonation time before and 2 months after treatment. The longest breath holding time in water of the hydrotherapy group were recorded. ResultsThe vital capacity (VC), expiratory reserve volume (ERV), inspiratory capacity (IC), forced vital capacity (FVC), forced expiratory volume in one second (FEV1), maximum ventilatory volume (MVV), peak expiratory flow (PEF) in all the children decreased significantly compared with the predicted value (P=0.000), but a second rate (FEV1/FVC) didn't （P=0.141）. After treatment, the VC, FVC, FEV1, FEV1/FVC, MVV, PEF values and their percentage of predicted value improved （P＜0.05）, as well as the maximum phonation time （P＜0.05）. ERV, IC values and their percentage of predicted value improved a little from pre-treatment in the control group （P＞0.05）, but significantly in the hydrotherapy group （P<0.05）. The percentage of predicted value of VC, ERV, IC, FVC, FEV1, FEV1/FVC, MVV, and PEF, and the maximum phonation time improved more in the hydrotherapy group than in the control （P＜0.05）. The longest breath holding time in water improved in the hydrotherapy group after treatment （P=0.000）. ConclusionThe pulmonary function impaired in spastic diplegic children, and can be improved with the rehabilitation, especially with the hydrotherapy in addition.

OBJECTIVE: To evaluate the influence of fewer courses and prolonged intervals of chemotherapy on survival rate of advanced non small cell lung cancer (NSCLC) patients treated by sequential chemo-radiation therapy combined with traditional Chinese medicine (TCM). METHODS: From Jan. 2000 to Dec. 2001, 54 untreated advanced NSCLC patients (2 stage IIIa, 18 stage IIIb, 34 stage IV) were treated by sequential chemo-radiation therapy combined with TCM. The courses of chemotherapy were reduced and the intervals of chemotherapy were longer than that of the standard regimen. The efficacy and survival rate were documented and the prognostic factors were analyzed. RESULTS: Complete remission (CR) was observed in 1 case and partial remission (PR) in 20 cases. The overall objective response rate was 40.4%. Median survival was 15.3 months, 1-, 2- and 3-year survival rate were 53.7%, 28.9% and 9.6% respectively. The median survival of stage III and IV were 21.8 months and 12.5 months respectively. The 1-, 2-, and 3-year survival rates of stage III were 65.0%, 49.5%, 24.7% and that of stage IV were 47.0%, 23.3%, 0%, respectively. The quality of life was improved in most of the patients. Cox's proportional hazards regression showed that improved quality of life and treatment of TCM were the significant prognostic factors of overall survival. CONCLUSION: Chemotherapy and radiotherapy combined with TCM is beneficial to extending the interval of chemotherapy, improving the quality of life, and increasing the survival rate of advanced NSCLC patients.

To observe the dynamic change of parasites in the brains of BALB/c mice infected with Angiostrongylus cantonensis in order to explore its possible mechanism of pathogenesis', BALB/c mice infected with the III stage larvae of A.cantonensis were observed and killed in different times after infection. The number and distribution of parasites in the brains of the infected mice were observed microscopically and macroscopically. It was found that the larvae of A.cantonensis were distributed in the cerebrum and cerebellum of mice in accordance with the rule of parasitization of worms in the host, i.e.multiplication at first and then dropping in number. And the places where the parasites located were damaged due to mechanical action or inflammatory reactions. The time of onset of symptoms, such as ataxia and twitch was coincided with the dynamic changes in the brains of the infected mice.

: Objective To evaluate the value of rehabilitation direction for the treatment of the children with spastic cerebral palsy. Methods 116 children with spastic cerebral palsy were investigated. 56 children who accepted rehabilitation direction and training in family participated in study group and 60 children who wouldn't accept rehabilitation direction participated in control group. All the children received comprehensive rehabilitation treatment in hospital, including physical therapy, acupuncture, low frequency electrotherapy and occupational therapy. All the children were assessed with Gross Motor Function Measure-88 (GMFM) before and 3 months after treatment. Results There was a significant difference before and after treatment in scores of GMFM in each dimension and total in both groups (P<0.01), and the treatment group improved more than control group(P<0.05). Conclusion Rehabilitation direction can facilitate the recovery of spastic cerebral palsy children.

Objective To evaluate combined effect on different population through 2 459 data of SAA,hs-CRP and PCT from 8 three-level hospitals in Guangdong region.Methods Subjects were divided into five groups by ages,and every group had bacterial and virus type.In order to confirm diagnostic effect on infection,methods were performed including in tendency of SAA and hs-CRP,Paired t test between bacterial and virus group,efficiency of 3 indexes in judging infection depending on ROC and parameters,multiple logistic regression,consistency between positive bacterial infection and bacterial culture.Re-sults There were statistically significant differences in SAA and hs-CRP between bacterial and virus in infants and children (P <0.001).SAA had the biggest AUC area 0.824 with sensibility 71.8% and specificity 82.6% in younger group.Corre-sponding,hs-CRP had the biggest area 0.806 with sensibility 84%.There was the accuracy of 78.8% for differential diagno-sis in younger group,while 65.1% in elder group.AUC of SAA was 0.883 for positive bacterial culture with sensibility 71.2% and specificity 90.7%,accuracy of 95.2% for differential diagnosis.Conclusion There was obvious trend of age in SAA and hs-CRP,3 indexes could be used for differential diagnosis alone or combined,especially in younger group.SAA is the best index as a separated index.There is less value at ratio of SAA and hs-CRP.

Objective To investigate the regulatory role of HK2 in the metastasis of hepatocellular carcinoma ( HCC) . Methods The protein expressions of HK2 in 73 HCC tumor tissues and paired adjacent non?tumor tissues were evaluated by using immunohistochemical analysis. The scratch wound healing assay and Transwell assay had been used to analyze the migration and invasion of HCC cells with HK2 knockdown. Expressions of epithelial?to?mesenchymal transition ( EMT) markers, such as E?cadherin, ZO?1, N?cadherin and vimentin,in HCC cells with HK2 knockdown were determined by qRT?PCR and Western blot analysis. Results The expression levels of HK2 in tumor tissues and adjacent non?tumor tissues were 5.39±3.40 and 2.16±1.55, respectively. The protein expression of HK2 was significantly higher in tumor tissues compared with adjacent non?tumor tissues of HCC (P<0.05). Knockdown of HK2 in HCC cells decreased the cell motility from 1.00±0.54 to 0.56±0.09 (P<0.05), andknockdown of HK2 in HCC cells decreased the number of invaded cells form 345±42 to 215±34 (P<0.05). The expression of epithelial markers ZO?1 and E?cadherin were up?regulated, while mesenchymal markers vimentin and N?cadherin were down?regulated in HCC cells when HK2 was knockeddown. Conclusions HK2 is up?regulated in HCC and promotes cell motility by stimulating EMT.

OBJECTIVETo investigate the apoptosis rules of the astrocytes and oligodendrocytes induced by Ca(2+) reperfusion.

METHODSThe apoptosis of purified cultured astrocytes and oligodendrocytes induced by Ca(2+) reperfusion and the relationship between the development of the cell apoptosis and post-reperfusion time was observed.

RESULTSBoth the astrocytes and oligodendrocytes were obviously in a time-dependent fashion, and the apoptosis ratios of the oligodendrocytes (39.73%+/-4.16%) were higher than the astrocytes (19.64%+/-4.67%) 24 hours after Ca(2+) reperfusion. The TUNEL positive cells were 13.6+/-1.82 and 21.4+/-1.95 at every visual field of astrocytes and oligodendrocytes respectively 24 hours after Ca(2+) reperfusion.

CONCLUSIONSThe astrocytes and oligodendrocytes are similar wi th the development rules on apoptosis and have different susceptiveness to the situation.
