Objective To investigate the distribution of camptothecin(CPT),tryptophan synthase(TSB),and tryptophan decarboxylase(TDC) in Camptotheca acuminata seedlings.Methods The CPT content,TSB and TDC activities in different organs of C.acuminata seedlings subjected to different nitrogen forms treatments by sand culture in greenhouse were determined by HPLC.Results The CPT content in the young leaves of C.acuminata seedlings with different N-forms was significantly higher than that in other organs(P

Objective To investigate the feasibility of video-assisted thoracoscopic sympathetic trunk clipping in the treatment of craniofacial hyperhidrosis. Methods A total of 10 patients were operated on under general anesthesia with double-lumen endotracheal intubation. The patients were placed in lateral recumbent position with one-lung ventilation. A 7 mm trocar and a 4.5 mm trocar were inserted at the 2~3 intercostal space on the midaxillary line and at the 4~5 intercostal space on the posterior axillary line, respectively, to introduce surgical instruments and thoracoscopic camera. Alongside the sympathetic chain, the sympathetic nerve trunk immediately below the second costal margin was blocked with small-sized titanium clips. Then the lung was inflated and the incision sutured. Afterwards, the procedure in the contralateral hemithorax was performed using the same method. Results The operating time was 55~130 min (mean, 110 min). Symptoms of craniofacial hyperhidrosis disappeared in the 10 patients, all of who were satisfied with curative results. The postoperative hospital stay was 2~3 days. Neither Horner’s syndrome nor other serious complications were observed. Seven of the patients developed slight compensation hyperhidrosis in their chest, abdomen, back or legs. All the patients had normally returned to work and physical exercises in 7~10 days. Postoperative follow-up for 1~9 months (mean,6.3 months) in all the patients found no recurrence. Conclusions Video-assisted thoracoscopic block of sympathetic trunk below the second costal margin for craniofacial hyperhidrosis is safe and effective.

Objective:To analyze the immunotherapy and clinical characteristics of coronavirus disease 2019 (COVID-19) patients, and focus on exploring the effects of immunotherapy and mesenchymal stem cells (MSC) transplantation in the critically ill patients' treatment.Methods:Fity-five COVID-19 patients were admitted to the Fifth People's Hospital of Wuxi from January 23rd to March 31st, 2020 as the research object. The demographic characteristics of the cases and the methods of immunotherapy were analyzed, focusing on the immunized indicators, positivity of pathogens and clinical indicators of critically ill COVID-19 patient, and the effects of immunotherapy and stem cell transplantation were evaluated.Results:Aged, male and people with comorbidities were the main risk factors in the development of severe and critical COVID-19. All of confirmed COVID-19 cases (n = 55) had been treated with interferon-α (IFN-α), of which 81.8% (n = 45, mild and ordinary) of the patients were recovered, 14.6% (n = 8) of the patients were converted to severe, 3.6% (n = 2) of the patients were converted to critical, and some severe patients were treated with gamma globulin and albumin as adjuvant treatment. Critically ill patients were not only treated with IFN-α, gamma globulin and albumin, but also treated with convalescent plasma and MSC transplantation. Due to pulmonary hemorrhage and persistently low blood oxygen saturation, terminal lung transplantation therapy was implemented. The total number of lymphocytes, CD4 +, CD8 + T lymphocytes, natural killer (NK) cells and B cells in peripheral blood of the two critical COVID-19 patients were significantly reduced, and the functions of lung, liver, and kidney were severely damaged on admission, manifested as significant increase of the levels of blood C-reactive protein (CRP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and blood urea nitrogen (BUN), etc. and decrease of blood oxygen saturation, and type Ⅰ respiratory failure, and the noninvasive assisted ventilation was needed to improve. After adjuvant immunotherapy such as gamma globulin, the nucleic acid of 2019 novel coronavirus (2019-nCoV) turned into negative. The CRP of one critically ill patient was significantly lower than the value at admission (minimum of 21 mg/L). But the lung inflammation progressed rapidly, and the pathological results of the lung tissue from the lung transplantation showed hemorrhage and irreversible fibrosis. The ability to secrete immunoglobulin A (IgA) was significantly reduced. Liver function had been significantly improved and stabilized after treatment with convalescent plasma during the recovery period. MSC transplantation treatment reduced the BUN level by > 50% compared with the previous period, and the total number of lymphocytes in the patient increased by more than 2 times (rose from 0.23×10 9/L to 0.57×10 9/L), but the total amount of lymphocytes was still lower than the normal reference value (< 1.1×10 9/L). The lung inflammation lesions were obviously absorbed, and the vital signs were stable. Conclusions:In addition to IFN, gamma globulin, antiserum and MSC transplantation therapy can help clear the virus and reduce inflammation. Although MSC transplantation fail to completely change the immunecompromised state of critically ill patients, it controlled the progression of inflammation in the liver and kidneys.

Objective To determine main factors associated with quality of life in epileptics in northen China especially seizure severity and stigma, and the variations between men and women. Methods All patients with epilepsy aged 18-65 years were selected from the First Affiliated Hospital of China Medical University, tested from March 2014 to March 2015. All of them completed the general social science data, the Quality of Life Inventory in Epilepsy-31 (QOLIE-31), Liverpool Adverse Events Profile (LEAP), the National Hospital Seizure Severity Scale (NHS3), Epilepsy Stigma Scale (ESS), Self-rating Anxiety Scale ( SAS) and Hamilton Depression Scale ( HAMD) assessment. Results A total of 123 patients with epilepsy (60 men, 63 women) were interviewed. QOLIE-31 scores were 55. 81 ± 10. 17 in female patients, 65. 35 ± 10. 89 in male patients, the difference being statistically significant (t=2. 90, P<0. 05). ESS (1(0,2)), SAS(31. 85 ± 8. 16), HAMD (4. 38 ± 2. 90) scores of female patients were higher than that of male patients (0(0,0), 26. 93 ± 3. 45, 2. 80 ± 1. 39;U= -2. 710, t=2. 48, 2. 20, all P<0. 05). Multiple factors analysis and multiple stepwise regression analysis on quality of life revealed that depression (β= -0. 516, P<0. 01) and the severity of epilepsy (β= -0. 338, P=0. 01) were two strong predictors of QOLIE-31 overall scores. The linear regression showed that there was a direct link between shame and degree of depression (β = 0. 515, P= 0. 001 ) . Conclusions The main factors affecting the quality of life in epileptics in northen China are depression and seizure severity. Compared with male patients, female patients have a lower quality of life, and poorer psychological status, such as shame, depression and anxiety. There is a direct link between shame and depression in epileptics.

CONCLUSIONS Humen are the main facters that make the air polluted in these wards.The bacteria content will decline by good environment cleaning sanitation,ventilation and strengthening steriling management.Infection will decline in the hospital.

Objective: To develop the Chinese version of the Neuropsychiatric Inventory Questionnaire (NPI-Q) and evaluate its reliability and validity. Methods: Three investigators assessed 10 dementia cases together with the NPI-Q to evaluate the inter-rater reliability. Eighty-six dementia cases and 30 healthy controls were assessed with the Behavioral Pathology in Alzheimer's Disease (BEHAVE-AD), the Brief Psychiatric Rating Scale (BPRS) and NPI-Q to evaluate the criterion validity. A subgroup of 30 dementia cases was tested with the NPI-Q again 24 h later to evaluate the test-retest reliability. Results: (1) Internal consistency. Cronbach's a coefficient of the severity subscale was 0.589, mean inter-item correlation coefficient of the severity subscale was 0.107. Cronbach's α coeffi-cient of the distress subscale was 0.612, and the mean inter-item correlation coefficient of the distress subscale was 0.114. (2) Inter-rater reliability. Intraclass correlation coefficient (ICC) of the severity subscale was 0.97, and ICC of the distress subscale was 0.94. (3) Test-retest reliability. The test-retest correlation coefficient of the severi-ty subscale was 0.89, and the test-retest correlation coefficient of the distress subscale was 0.86. (4) Criterion va-lidity. The severity subscale total score was correlated significantly with BEHAVE-AD (r=0.70, P <0.001) and BPRS(r=0.40, P<0.001) total score; the distress subscale total score was correlated significantly with the global ratings in part 2 of BEHAVE-AD (r=0.76, P<0.001) . (5) The severity subscale total score in demen-tia group was significantly higher than that in control group (median: 10 vs.1.5, P <0.001). The distress sub-scale total score in dementia group was significantly higher than that in control group (median: 10 vs 0; P< 0.001) . (6) Exploratory factor analysis identified 4 common factors, including psychosis, abnormal behavior,discontrol and affective symptoms, which explained 58.3% of total variance. All of the items loaded were between 0.596 and 0.803 on their conrresponding factor. Conclusion: The reliability and validity of the Chinese version of NPI-Q meet the psychometrics properties, and deserves to conduct further study in larger samples.

Objective To investigate the effect of Terpinen-4-ol on the proliferation of lung adenocarcinoma A-549 cells and its related mechanism. Methods A-549 cells were treated with different concentrations of Terpinen-4-ol. The inhibitory effect of Terpinen-4-ol on A-549 cells was tested by MTT method. Cell grow ability was determined by CCK-8 colorimetry. The ultrastructure of A549 cells were observed by transmission electron microscopy before and after Terpinen-4-ol treatment. The changes of cell cycle, apoptosis, and the level of intracel-lular calcium were inspected by flow cytometry. Inoculated the lung adenocarcinoma A-549 cells on the nude mice to form transplantation tumor. The experimental nude mice with transplantation tumors were divided into three groups:negative control group,high dose positive con-trol group and low dose positive control group. The mice were given continuously intraperitoneal injection for 10 days, and then the transplan-tation tumors were taken and the size and weight of them were detected. Results After Terpinen-4-ol treatment for 24 h,MTT assay showed that the IC50 value of A549 cells was 0. 067% v/v. The growth curves of positive control groups were significantly smooth than the negative control group. The formation of autophagosome increased after treatment with Terpinen-4-ol. The results of flow cytometry showed that the cell cycle was arrested in S phase,Terpinen-4-ol could induce apoptosis of A549 cell, The intracellular calcium concentrations in positive control groups were significantly higher than the negative control group(P<0. 05). Low dose group and high dose group restrained the growth of the transplantation tumor obviously, and the tumor inhibitory rate were 53. 33% and 77. 76% respectively. Conclusion Terpinen-4-ol has inhibitory effect on the proliferation of A-549 cells in vitro and in vivo.

The resident standardized training is an important stage in clinical medical personnel training sys-tem. Medical ethics education and accomplishment is one of the main training contents in this stage is, the necessa-ry requirement for physician growth, and the effective guarantee for training organization and implementation. Learning for relevant theory of medical ethics is the basis of medical ethics education, and the medical practice is the fundamental way of medical ethics accomplishment. In medical practice, the inner perception is the gradual sublimation of medical ethics accomplishment. The formation of residents′ medical ethics quality is dominated by heteronomy and guided by medical morality code. It emphasizes more on self-regulating the ethical behaviors and abiding by medical ethics faith and standards.
