Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in Wuhan, Hubei Province in December 2019, with severe acute respiratory syndrome (SARS) in 2002 and Middle East respiratory syndrome (MERS) in 2012 are all infectious diseases caused by coronavirus. According to the knowledge of infectious diseases such as SARS and MERS, many patients and health care workers suffered from depression and anxiety during and after the epidemic. In particular, post-epidemic survivors were more likely to suffer from post-traumatic stress disorder (PTSD). Similar conditions could be occurred during and after COVID-19. Therefore, it is also an important task to reduce the prevalence of PTSD after COVID-19 as much as possible and to relieve the tension of infected patients, first-line medical staff, quarantine personnel and so on. Traditional Chinese medicine has unique advantages in the treatment of emotional diseases. Understanding the etiology and pathogenesis of PTSD by theory of traditional Chinese medicine and looking for effective methods to treat PTSD will be helpful to treat PTSD of survivors after COVID-19. It is found that Sini Powder has potential value in the treatment of PTSD by the summary and comparison of the research on traditional Chinese medicine related to the treatment of PTSD. We hope to overcome this epidemic psychologically and spiritually. Therefore, it is considered that Sini Powder can be used as the first choice for relieving emotional diseases of related patients during COVID-19 and treating PTSD of survivors after COVID-19.

AIM: To express chimeric toxin Stx2a’-LHRH a nd to investigate the cytotoxic activity of recombinant toxin Stx2a’-LHRH to huma n carcinoma cells.METHODS: Stx2a’-LHRH sequences that added the res tri ction endonucleases NcoⅠ and EcoRⅠ at the 5' and 3 ends were amplified by PCR a nd digested with appropriate restriction enzymes. The digested fragment was subc loned into the vector obtatined by digestion of plasmid pET-28a(+) with NcoⅠ an d EcoRⅠ. E. coli BL21 (DE3) cells were transformed with plasmids of interst and cultured in LB medium containing ampicillin. Expression of the recombinant protein was induced by the addition of isopropylthio-?-D-galactoside (IPTG). T h e cytotoxity of Stx2a’-LHRH to Hep-2 cells was observed under the microscop y. RESULTS: Recombitant plasmid pET-SL was constructed successfu lly and the clones expressing pET-SL stablely were obtained. A special electroph oretic band in SDS-PAGE (a glycoprotein of 28kD) was noted. Stx2a’-LHRH killed He lp-2 cells clearly. CONCLUSION: In this study, construction of c himeric toxin Stx2a’-LHRH and its expression were described. Moreover, it has o bvious cytotoxity to Hep-2 cell. These finding could open up new vistas in the s tudy of targeted durgs.

Objective To compare the effects,stress reaction and concentration of ropivacaine in umbilical cord blood of patients who accepted combined spinal epidural analgesia or patient controlled epidural labor analgesia in latent and active phase.Methods After approved by the ethics committee and informed consents from 80 nulliparous parturients who were admitted to Beijing Friendship Hospital,Capital University of Medical Sciences between January to June 2009,and who were term,single,cephalic presentation delivery and ASA Ⅰ-Ⅱ,were divided into two groups randomly:latent phase group (Group L,cervical dilation 0.5-2.5 cm,n=40) and active phase group (Group A,cervical dilation ≥3.0 cm,n =40).Ropivacaine 2 mg and fentanyl 10 μg was administered in subarachnoid space of all patients.Then,patient controlled epidural infusion of 0.1 ％ ropivacaine plus fentanyl 2 μg/ml were administered.Pain scores (visual analogue score,VAS),lower extremity muscle strength,duration of labor,delivery mode,total dosage used,maternal satisfaction,Apgar score (1 min and 5 min) were evaluated; concentration of ropivacaine (high performance liquid chromategraphy) in cord blood,and concentration of cortisol (radioimmunoassay) in maternal venous blood and cord blood were detected.Forty nulliparous parturients without labor analgesia were taken as control group (Group C).Chi-square test and one way analysis of variance was applied for statistical analysis.Results (1) VAS in Group L and Group A were lower than that of Group C when cervix dilated at 7.0-8.0 cm (2.9± 1.4,2.6± 1.5 vs 9.2±0.7,F=201.50,P＜0.01) and fully dilated (4.7±2.2,3.6±2.0 vs 9.1±0.7,F =-62.07,P＜0.01,respectively).(2) Tbe concentration of cortisol in maternal venous blood right after delivery was higher than that before analgesia in all groups,and the change in group C was significantly greater than that in group L and group A [(902±172) μg/L vs (761±125) μg/L and (731±184) μg/L,t =-3.491 and-3.483,all P＜0.01],moreover there was no significant difference between group L and group A (P＞0.05).There were no difference in cortisol concentration of umbilical blood among the three groups [(168±46) μg/L,(159±49) μg/L and (170±86) μg/L,F=0.23,P＞0.05].(3) There was no difference between ropivacaine concentration in umbilical blood of group L and group A [(0.21±0.10) mg/L vs (0.20±0.03) mg/L,t=0.557,P＞0.05].(4) No significant differences was shown among the three groups in the duration of first and second stage of labor,rate of augmentation,neonatal birth weight,Apgar score at 1 min and 5 min (all P＞0.05).Compared with group C,group L and group A had higher rate of vaginal delivery (52.5％ vs 75.0％ and 85.0％,P＜0.05) and lower rate of cesarean section (45.0％ vs 20.0％ and 15.0％,P＜0.05).The duration of analgesia in group L was longer than that in group A [(215±143) min vs (118±50) min,t =3.722,P＜0.01] and the dosage of fentanyl was also higher [(28± 11) μg vs (17±6) μg,t =5.084,P＜0.01].Conclusions Labor analgesia with combined spinal epidural could decrease cesarean section rate and maternal stress reaction without prolonging the duration of labor and inhibiting neonatal stress reaction.Labor analgesia start from latent phase would not increase the concentration of ropivacaine in cord blood.

Objective To explore the level of serum transforming growth factor-β1 (TGF-β1) in patients with prehypertension and impaired fasting blood glucose.Methods A total of 180 healthy subjects with matched age and sex was divided into 3 groups:group A (blood pressure ＜ 120/80 mmHg and fasting blood glucose ＜6.1 mmoVL),group B (prehypertension and fasting blood glucose ＜6.1 mmol/L),group C (prehypertension and 6.1 mmol/L≤ fasting blood glucose ≤7.0 mmol/L).There were 60 subjects in every group.Serum TGF-β1 was measured by Enzyme-Linked Immunosobent Assay (ELISA),fasting blood glucose,triglyceride,total cholesterol,low-density lipoprotein cholesterol ( LDL-C),high-density lipoprotein cholesterol ( HDL-C),Uric Acid ( UA),body mass index (BMI) were determined.Results The level of serum TGF-β1 in group B and C was higher in that in group A( t =2.071,and 2.147,P ＜0.05 ).The level of serum TGF-β1 was higher in group C than group B,but no significant difference was observed ( P ＞0.05).The pearson correlation analysis showed there was a significant correlation between TGF-β1 and systolic blood pressure ( r =0.279,P =0.047).Conclusions The level of serum TGF-β1 was higher in patients with prehypertention which may mediate the target organ damage caused by the prehypertention.

Objective: To investigate the expression of EMS1 in laryngeal carcinoma and its clinical signifi-cance. Method:The expression of EMS1 protein was measured in 40 samples of, 40 samples of para carcinoma tis-sues (which were near to cutting margin of laryngeal carcinoma tissuse over 0. 5 cm) ,and 20 samples of normal la-ryngeal mucosa as controls by Flow Cytometere( Epics-XL Ⅱ ). Results:The quantity and percentage of EMS1 pro-tein expression in laryngeal carcinoma tissues was significantly higher than those in para carcinoma and in normal laryngeal mucosa tissues respectively(P<0. 05). There was no significant expression difference between the para carcinoma tissues and normal laryngeal mucosa tissues. There were positive correlation between the expressions of EMS1 protein and metastasis, pathological grade and clinical stage in laryngeal carcinoma. But there were not rela-tionship with patients' clinical classification, tumor size, smoking history, age and sex. Conclusion: The high ex-pression of EMS1 may contribute to the carcinogenesis and development of laryngeal carcinoma. The expression of EMS1 protein is an important index of judging differentiation, infiltration, metastasis and staging of laryngeal car-cinoma.

Objective To analyze the advantage of altered fractionation radiotherapy by calculating the accumulative effects of daily biologically effective dose (BED) to find out the difference between conventional fractionated radiotherapy and altered fractionation radiotherapy.Methods The data in the report of hyperfractionated or accelerated radiotherapy for head and neck cancer published by Cochrane Collaboration in 2010 was analyzed.Based on the radiotherapy processes mentioned in this report,the accumulative effects of daily BED were calculated and compared in different radiotherapy processes by using linear-quadratic mode.The variation of BED in different radiotherapy processes was find out.Results In total dose of unity as the premise of 70 Gy,altered fractionation especially the hyperfractionated accelerated radiotherapy could give a higher BED to the tumor during a shorter period,hyperfractionated radiotherapy could give a lower BED to normal tissues,and hyperfractionated radiotherapy with split course could give higher BED to the tumor while lower BED to normal tissues.Conclusions The variation of BED in different radiotherapy processes can be shown clearly by linear-quadratic mode.It can be simple and shortcut through mathematical models for the evaluation of different radiotherapy plan,on clinical symptomatic selection play a guiding role in tumor therapy.
