Objective To evaluate the therapeutic efficiency and side effect of concurrent radiotherapy and weekly chemotherapy with low-dose eisplatin(DDP) and 5-fluorouracil(5-FU) for advanced cervical canc-er. Methods 73 patients with advanced cervical cancer were randomized into two groups: 37 cases in the chemo-radiotherapy group received radiotherapy combined with DDP 40 mg and 5-FU 500 mg weekly for 6-7 weeks. 36 cases in the only radiotherapy group received radiotherapy alone. Radiotherapy was given with conven-tional fraction,the total tumor dose was 50 Gy. Results The rate of overall response and three-year survival and local recurrenc and distant metastasis for the chemo-radiotherapy group and the only radiotherapy group were 97.30%, 89. 19%, 8. 11% and 10. 81%, and those for the only radiotherapy group were 77.78%,66. 67% ,30.56% and 33.33%. The difference of the four groups was statistically significant ( P <0. 05). The rate of bone marrow inhibition and reaction of digestive tract in chemo-radiotherapy group were higher than those in simple radiotherapy group, but most reactions were grade 1 and grade 2, without statistically significant dife-renee between two groups. Conclusion Concurrent radiotherapy and weekly chemotherapy with low-dose cis-platin and 5-fluorouracil for advanced cervical cancer can significantly improve local control rate and survival rate, and have slight side effects.

AlM: To explore the clinical significances and changes of related parameters of corneal endothelial cell in keratouveitis patients before and after treatment.
METHODS:Fifty-two keratouveitis patients ( 52 eyes ) diagnosed and treated in our hospital from October 2012 to December 2013 were collected. Before and after treatment, the related parameters of corneal endothelial cell in all patients were measured with non - contact corneal specular microscope and these parameters were statistically analyzed.
RESULTS: Compared with the normal group, obvious endothelial cell edema and great variation was observed in diseased group. The shorter duration of treatment, the better the recovery of endothelial cells and the fewer cells lose. Conversely, the longer the healing of normal hexagonal cell ratio was smaller, the larger the coefficient of variation. Before and after treatment, the differences of each parameter were statistical significance (P<0. 05).
CONCLUSlON: The functional recovery of corneal endothelial cell has directly relation with disease times.

Objective To learn the present efficiency of medical equipments at public hospitals in Liaoning province, and provide scientific basis for rational distribution of such resources, and for control of medical expenses.Methods Data envelop analysis (DEA) was used to appraise the deployment efficiency of 2 784 such equipments worth over 100 000 yuan per unit, with equipments randomly sampled from 31 public hospitals in the province.Results The equipment deployment at public hospitals in Liaoning was found at a low level.9.7% of the hospitals were found as relatively efficient, 3.2% of them as in relatively weak efficiency, while 87.1% of them relatively inefficient.Gaps were found between urban hospitals and tertiary hospitals, and rural hospitals and secondary hospitals in their deployment efficiency, as evidenced in overinvestment of equipments and insufficiency of competent operators.Conclusions Hospitals should strengthen their scientific management of the equipments, and emphasize human resource investment, thus elevating the efficiency of equipment deployment.

Objective To observe the therapeutic effect of the Valpar system combined with computer-aided technology in treating early vascular cognitive impairment (VCI).Methods Forty patients in the early stage of VCI were randomly divided into a treatment group and a control group,each of 20.Regular and computer-aided cognition training were applied in both groups,while training using the Valpar system was additionally used in the treatment group.Patients in both groups were assessed using the Loewenstein Occupational Therapy Cognitive Assessment (LOTCA) and the modified Barthel Index (MBI) before,and after 4 and 8 weeks of treatment.Results Before the treatment,there were no significant differences between the 2 groups in LOTCA and MBI scores (P＞0.05).After 4 and 8 weeks of treatment,the average total LOTCA score in the observation group was significantly better than before the treatment,as were the average scores on the various dimensions,and the average MBI score (P＜0.05).After 4 weeks of treatment the control group showed significant improvement in the patients' orientation (3.50±0.89),visual perception (13.50± 1.43),spatial perception (2.40±0.50),visuomotor construction (24.00± 1.17) and attention (2.30±0.87).However,after both 4 and 8 weeks of treatment,all the measurements of the observation group were significantly better than those of the control group at the same time point (P＜0.05).Conclusion The Valpar system can significantly improve the recovery of cognitive function and ability in the activities of daily living of patients in the early stage of VCI.It is worth applying in clinical practice.

OBJECTIVETo study pharmacokinetic effect of Aikeqing Granule (AG) by different medication ways on zidovudine (AZT) in highly active antiretroviral therapy ( HAART) of rats.

ObjectiveTo evaluate the efficacy of PEEP set according to pressure-volume (P-V) curve for one lung ventilation (OLV) in patients undergoing thoracic surgery.MethodsOne hundred and twenty ASA Ⅱ or Ⅲ patients of both sexes aged 20-60 yr weighing 40-80 kg undergoing lobectomy under general anesthesia were enrolled in this study.Double lumen tube was inserted.Correct positioning was verified by fiberoptic bronchoscopy.The patients were mechanically ventilated.P-V curve was determined at 3 min of two-lung ventilation (TLV).Lower inflection point (LIP) was measured and the pressure at LIP (PLIP) was recorded.The patients were randomly divided into 5 groups (n ＝ 24 each):control group (group C) and 4 lung protective ventilation regimen groups ( groups P1-4 ).PEEP was set at 0 and VT was set at 10 ml/kg in group C.PEEP was set at 0 and VT was set at 6 ml/kg in group P1.PEEP was set at PLIP- 2 cm H2O and VT was set at 6 ml/kg in group P2.PEEP was set at PLIP and VT was set at 6 ml/kg in group P3.PEEP was set at PLIP + 2 cm H2O and VT was set at 6 ml/kg in group P4.Peak airway pressure (Ppeak),plateau airway pressure (Pplat),airway resistance (Raw) and lung compliance (CL ) were measured and recorded during OLV and TLV after a period of stabilization.Arterial blood samples were taken before induction of anesthesia and at 20 min of TLV and 20 min of OLV for blood gas analysis.Qs/Qt was calculated.Arterial blood samples were collected at the beginning and end of OLV for determination of plasma concentrations of IL-6 and TNF-α(by ELISA).ResultsCompared with group C,Ppeak and Pplat were significantly increased while Raw was decreased and plasma IL-6 concentration was significantly decreased at the end of OLV in group P4.PaCO2 was significantly higher during TLV and OLV in groups P1-4 than in group C.There was no significant difference in the parameters of respiratory mechanics,blood gases and plasma IL-6 and TNF-α concentrations among groups P1,2.3.Compared with groups P1,2,3,Ppeak and Pplat were significantly increased while plasma IL-6 concentration was decreased at the end of OLV in group P4.ConclusionMechanical ventilation with VT set at 6ml/kg and PEEP at PLIP + 2 cm H2 O provides best venfilatory efficacy for OLV in terms of oxygenation and inhibition of inflammatory response.

Objective To investigate the episodes and influencing factors on self-harm and to explore the relationship between self-harm episodes and suicidal psychology and behaviors in college students. Methods Four universities were selected using cluster sampling method in Anqing city and Chaohu city. Totally, 2713 college students completed this survey. Data were analyzed by Pearson Chi-square and logistic regression. Results In the last six months, rates of highly lethal self-harm,less lethal self-harm with visible tissue damage, self-injury without visible tissue damage,self-harmful behaviors with latency damage, other self-harmful behaviors with menticide were 1.9%,5.5%, 15.3%, 21.2% and 17.0% respectively. The total rate of self-harm was 31.3%. 73.1% of the students with self harmful experiences had the above mentioned behaviors more than 3 times in the last six months. The top 3 reasons for taking self-harm actions were: having learning problems (43. 1% ), failed love affairs (25.0%) and having conflicts with others (23.9%). There were different influencing factors among different kinds of self-harm episodes. Depression was the risk factor of self-harm. The higher score of having high self-esteem was the protective factor of all kinds of self-harm actions except highly lethal ones. Higher score of difficulties in identifying feelings was one of the risk factors. The rates of suicidal psychology and behaviors in students with self-harm were significantly higher than those in students without those behaviors. Result from linear x2 test indicated that the graveness of tissue damage of self-harm was higher along with the rates of suicidal psychology and behaviors (P＜0.01). Conclusion Among 2713 college students, about 1/3adolescents having experienced self-harm in the last 6 months, many with repeated ones. Depression and difficulties in identifying feelings were the two risk factors while self-esteem was the protective factor related to most of the self-harm cases.

Aim To investigate the protective role of salvianolic acid B ( Sal B ) on cardiac hypertrophy in type 2 diabetes mice , and to explore its influence on peroxisome proliferator activated receptors-α( PPARα) .Methods The type 2 diabetes melitus ( T2DM) mouse model was established by 4 weeks ' high fat diets feeding and one time STZ intraperitoneal injection .The animals were randomly divided into:control, T2DM, T2DM+SalB(100 mg· kg -1 · d-1 ) and Sal B(100 mg· kg -1 · d-1 ) groups.Eight weeks later, heart weight, tibial length, cross section area of cardiomyocytes , protein expression of PPARαin heart tissue were recorded .In vitro, high glucose and high insulin ( HGI ) were used to induce hypertrophic growth in cultured neonatal rat cardiomyocytes ( NRC-Ms) .And cell surface area , 3 H-leucine incorporation , 3 H-D-glucose uptake and PPARαprotein level were measured to observe the effect of Sal B and MK 886, a PPARαinhibitor.Results In T2DM model mice, Sal B could lower heart weight/tibial length and cross sec-tion area of cardiomyocytes , while PPARαprotein level in hearts were improved .In cultured cardiomyocytes , Sal B ( 10 ～100 μmol · L-1 ) ameliorated the in-creased levels of cell surface area ,3 H-leucine incorpo-ration and improved the decreased 3 H-D-glucose up-take and PPARαexpression induced by HGI . But those function could be abolished by MK 886.Conclu-sion Sal B ameliorates cardiac hypertrophy in T 2DM mice, which may be related to its function on PPARαactivation .
