OBJECTIVE: To explore the risk factors of anxiety and depression in patients with suspected coronavirus disease 2019 (COVID-19) so as to achieve early intervention and better clinical prognosis. METHODS: Seventy-six patients with suspected COVID-19 in fever isolation wards of Second Hospital of Lanzhou University were enrolled From January 31, 2020 to February 22, 2020. Their clinical baseline data were collected. The anxiety of patients was assessed by Hamilton Anxiety Scale, and the depression of patients was assessed by Hamilton Depression Scale. Multivariate Logistic regression analysis was performed to explore the risk factors of anxiety and depression in these patients. RESULTS: Female patients are more likely to have anxiety (=3.206, 95%: 1.073-9.583, <0.05) and depression (=9.111, 95%: 2.143-38.729, <0.01) than male patients; patients with known contact history of epidemic area and personnel in epidemic area are more likely to have depression (=3.267, 95%: 1.082-9.597, <0.05). CONCLUSIONS During the isolation treatment of suspected COVID-19 patients, early psychological intervention should be carried out for the female patients with known contact history of epidemic area and personnel in epidemic area, and drug treatment should be given in advance if necessary.

Objective To explore the successful breastfeeding experience of primiparous women with natural childbirth during the first 6 months postpartum. Methods A phenomenological methodology was used. Semi-structured in depth interviews were conducted among 11 primiparous women of natural childbirth. The data were transcribed, collated, summarized and analyzed using Colaizzi′s method. Results The primiparous women who sustained exclusive breastfeeding for six months after natural delivery experienced three stages which were:anxiety of breastfeeding,gradual adaption of breastfeeding, and coexistence of puzzles and insistence. The first stage was anxiety of breastfeeding including three themes: lack of experience in breastfeeding, conflict of breastfeeding, and noticeable fatigue during feeding.The second stage was gradual adaption of breastfeeding including four themes:family and social support, presenting regular feeding schedules, identification of mother role, and establishing a good mother-child relationship.The last stage was coexistence of puzzles and insistence which containing three themes: coexistence of confusion and perseverance, fear of returning back to work, suffering of maternal separation,and commitment of breastfeed. Conclusions In order to release the anxiety and improve the confidence of breastfeeding of primiparous women, it is vital to rely on the conjoint efforts of the family members,healthcare institutions,communities,enterprises,society and other aspects to improve the rate and duration of exclusive breastfeeding.

Objective To observe the repeat administration toxicity of Guanxinning Injection in rats.Methods Totally 120 rats (males and females) were randomly divided into vehicle control group and three Guanxinning Injection groups with different dosages (3.40,1.70,and 0.85 g/kg).Rats were administered with Guanxinning Injection by consecutive intravenous injection for 13 weeks.Besides the general conditions were observed,the related indexes were detected,such as body weight,the routine control of blood,hepatic function,renal function,the metabolism condition of lipids,the glycometabolism indexes,and histopathology analysis were determined at 13 weeks of treatments and 4 weeks after the withdrawal,respectively.Results Rats in the Guanxinning Injection group at 3.40,1.70 g/kg apperance shortness of breath,unsteady gait,lying motionless,and other symptoms.There was no obvious abnormal reaction in the 0.85 g/kg dose group.There were two male rats in the Guanxinning Injection group at 3.40 g/kg died at about week 4 of treatments,and there was no death in the 0.85 and 1.70 g/kg dose groups.Compared with vehicle control group,the related indexes of blood,blood biochemistry,organ relative quality,and histopathological showed no obvious abnormalities in Guanxinning Injection 0.85 and 1.70 g/kg group.The levels of urea nitrogen (BUN) and the relative weight of kidney in Guanxinning Injection 3.40 g/kg group were significantly higher than those in vehicle control group at 13 weeks.The change of these parameters regained to normal at 4 weeks after withdrawal and the rest of the detection index showed no obvious abnormality in 3.40 g/kg dase group.Conclusion Intravenous administration of Guanxinning Injection for 13 weeks at high dose could induce reversible damage to kidney.

Objective To explore the role of TGF-βand TGIF in the pathogenesis of endometriosis. Methods The expression of TGF-β and TGIF was detected by immunohistochemistry method in the ectopic and eutopic endometrium of 30 cases with endometriosis (ec-topic endometrium group and eutopic endometrium group) and in the normal endometrium of 40 cases without endometriosis (control group). Result The expression of TGF -β in ectopic endometrium group was significantly higher than that in eutopic endometrium group and control group (P < 0.05). There was no significant difference in the expression of TGF- βbetween eutopic endometrium group and control group(P > 0.05). The expression of TGIF in ectopic endometrium group was significantly lower than that in eutopic endometrium group and control group( P <0.05). There was no significant difference in the expression of TGIF between eutopic endometrium group and control group(P > 0.05). There were negative correlation between the expressions of TGF - β and TGIF in ectopic endometrium group and eutopic endome-trium group(rs= - 0.769, - 0.549, P < 0.05). Conclusion The abnormal expression of TGF-β and TGIF in ectopic endometrium of pa-tients with endometriosis may be associated with the genesis and progression of endometriosis.

BACKGROUND:Donkey-hide glue reinforcing bone oral solution (DGRBOS) is effective on preventing and treating fracture, but the mechanism of harmacology is still not clear. Vascular endothelial growth factor (VEGF) and fibroblast growth factor 2 (FGF-2) are important cytokines, which can promote blood vessel growth and osseous anabolism during fracture healing.OBJECTIVE: To investigate the effects of DGRBOS on expression of VEGF and FGF-2 in the process of fracture healing of SD rats' fracture of tibia in bony callus, and explore the mechanism of DGRBOS in the treatment of fracture.DESIGN: A completely randomized controlled study.SETTING: Department of Traumatic Orthopedics, Union Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology.MATERIALS: Ninety female Sprague-Dawley (SD) rats, with a mean weight of (368±40) g, aged about 3 months, wereprovided by Center of Animal Experiment, Tongji Medical College, Huazhong University of Science and Technology.Experimental drug: DGRBOS was donated by Xinjiang Huashidan Pharmaceutical Co., Ltd. The qili linking bone pill,positive control drug, was purchased from Hunan Pharmaceutical Co., Ltd.METHODS: This experiment was carried out in the Laboratory for Bone Metabolism of Integration of Chinese and Western Medicine (Laboratory of Provincial Level), Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from June to November 2005. Transverse midshaft fractures were produced on the right tibia in these rats using three-point bending technique, and 90 rats were randomly divided into three experimental groups:the DGRBOS group (n =30): according to medicine conversional method between human being and animal, 2 mL DGRBOS was fed to every mouse by intragastric administration at 2 vices/day; the qili linking bone pill group (positive control group, n =30): the pills dissolved in distilled water at 225 g/L, and consequently were administered intragastrically into mice at 2 mL/vice and 2 vices/day; normal saline group (negative control group, n =30): normal saline was administered intragastrically into mice at the coordinative capacity and same frequences. Selecting 4, 7, 14,21 and 28 days during the experiment, the immunohistochemistry method was adopted to detect the change of expression of VEGF and FGF-2 through computing value of mean optical degree (MOD) and number of the positive cells.

AIM: To observe the early changes of local cerebral blood supply in dogs during the acute vertebral artery stenosis by 99 TcmECD cerebral blood flow perfusion imaging(CBFPI).METHODS: Twenty-four dogs were randomized into groups of normal controls(A),moderate stenosis(B),severe stenosis(C) and arterial occlusion(D),with 6 in each group.Group A were free from any intervention,but Group B,C and D were undergone ligation of the right vertebral arteries by the extent of 50%～69%(Group B),70%～99%(Group C) or 100%(Group D).The imaging agents were injected intravenously 0.5-1 h after ligation and the single photon emission computed tomography(SPECT) was performed after 1 h.RESULTS: CBFPI examination of the early changes of cerebral blood supply during the acute vertebral artery stenosis by visualization showed that the sensitivity was 33.3%,83.3% and 100% in Group B,C and D,respectively,with an average sensitivity of 72.2%,while semi-quantitative assessment suggested that the sensitivity was 50%,100% and 100% in the three groups,respectively,with an average sensitivity of 83.3%.When examining the activity ratio for regions of interest(ROI) by semi-quantitative 99 Tcm-ECD CBFPI,the findings suggested that Group D and C decreased significantly(exception in cerebellum in Group C),but Group B had no evident changes,as compared with Group A.By comparison of the groups of B-C,B-D and C-D,differences were observed in the right temporal lobes,whereas the changes in left temporal lobes were seen in Group B-C or B-D.The changes were seen in occipital lobes when groups of B and D were compared,but with no differences in cerebellum.CONCLUSION: The degree of stenosis in vertebral arteries may involve varied regions,the temporal lobe is susceptive,followed by occipital lobe,while cerebellum is somewhat resistant from the involvement.

Objective To discuss the effect and the method of treatment of anti-cardiolipin antibody (ACA),ANA and ENA on abnormal delivery women,and their relationship with abnormal delivery.Methods The concentrations of plasman ACA,ANA,ENA and the times of abortion in abnormal delivery for 193 cases of abnormal delivery women and 100 cases of normal pregnancy were quarnlitatively detected and satistically analyzed.The 81 ACA positive patients were treated orally with aspirin,25 ACA and ANA/ENA positive patients were treated with aspirin combined with prednisone,and 3 ANA/ENA positive patients with prednisone treatment oral.Results The number of ACA and ANA positive patients was closely related to the types of abmormal delivery. The ANA and ENA positive patients was related to the times of abortion. There was no difference in the outcome of treatment between both therapies of aspirine and aspirine combined with prednisone in abnormal delivery women.Conclusions ACA is an important factor in causing abnormal delivery. No matter what ANA and ENA are in ACA positive patients,their can be treated with aspirin alone.

Aim To study pharmacokinetics and bioavailablity of domestic penicillin V dispersion tablet in healthy volunteers. Methods According to the crossover design, each volunteer in two groups was orally given a single dose ( 0.75 g ) of domestic penicillin V dispersion tablet or imported penicillinV tablet alternately and the plasma concentrations were determined by RP HPLC. The pharmacokinetic parameters were obtained by using ATPK program and calculated on the basis of open single compartment model. Results After a single oral dose( 0.75 g ), the t 1/2(ke) was ( 0.75 ? 0.10 ) h and ( 0.70 ? 0.14 ) h ,the c max was( 8.44 ? 2.40 ) mg?L -1 and ( 8.75 ? 3.04 ) mg?L -1 at ( 0.56 ? 0.11 ) h and ( 0.63 ? 0.17 ) h and AUC 0～4 was( 8.44 ? 2.40 ) mg?h?L -1 and ( 8.75 ? 3.04 ) mg?h?L -1 for two formulations, respectively. Relative bioavailability of domestic penicillin V dispersion tablet was ( 90.50 ? 8.84 )%. Conclusion The result shows that the two formulations are bioequivalent.

AIM: To evaluate effects of diltiazem on platelet hyperreactivity in situations associated with endothelial injury and their possible relationship to cytosolic calcium concentration. METHODS: Blood samples were collected at 7 time points from 35 patients undergoing percutaneous transluminal coronary angioplasty (PTCA) who received combined diltiazem and aspirin/ticlopidine therapy or aspirin/ticlopidine therapy alone. Platelet expression of glycoprotein Ⅱb/Ⅲa and cytosolic calcium concentration were measured, respectively, by whole blood flow cytometry and fluorospectrophotometry. The effects of diltiazem of different concentrations on expression of glycoprotein Ⅱb/Ⅲa were also studied in vitro in blood samples from patients with chronic stable angina. RESULTS: Of the two treatments, aspirin/ticlopidine therapy did not prevent an acute increase of expression of glycoprotein Ⅱb/Ⅲa 5 minutes and 10 minutes after first inflation and 10 minutes after PTCA, whereas combined diltiazem and aspirin/ticlopidine therapy had a significant inhibitory effect. In the group receiving aspirin/ticlopidine therapy, there was a short-term elevation of platelet [Ca~(2+)]i immediately following PTCA which was significantly reduced by diltiazem treatment. Expression of glycoprotein Ⅱb/Ⅲa was significantly inhibited in vitro by diltiazem in the concentration of 200 ?g/L or higher, but not 50 ?g/L. CONCLUSIONS: Combined diltiazem and aspirin/ticlopidine therapy significantly inhibited platelet activation that continued in the presence of conventional aspirin/ticlopidine treatment. Antiplatelet effects of diltiazem were probably a consequence of reduction of platelet [Ca~(2+)]i and may only be achieved in higher than therapeutic concentrations. [
