Objective:To analyze the epidemiological, clinical characteristics and treatment of coronavirus disease 2019 (COVID-19) in Northeastern Sichuan, and summarize experience in time to provide reference for clinical diagnosis and treatment.Methods:A retrospective study was conducted. Fifty-nine patients with COVID-19 admitted to Bazhong Central Hospital and Dazhou Central Hospital from January 27th to February 9th, 2020 were selected as the subjects. The data of demography, epidemiology, laboratory examination, chest CT and related clinical treatment were collected. According to the severity of the disease, the patients were divided into three types: mild, general and severe types, and the differences of the above indices among different clinical types were compared.Results:① General information and epidemiology: 31 cases (52.5%) were male, 28 cases (47.5%) were female, the average age was (42.0±16.4) years old, and the patients over 40 years old accounted for the largest proportion (35 cases, 59.3%). The proportion of clinical type was 72.9% (43 cases) in general type, and 62.7% (37 cases) were imported type. With the increase of disease severity, the average age of patients also showed a significant increase trend [the age of the mild, general and severe patients were (30.9±13.6), (42.7±15.3), (55.8±18.9) years old, P < 0.01]. The proportion of patients with more than one basic disease in severe patients was significantly higher than those in mild and general patients [66.7% (4/6) vs. 20.0% (2/10), 9.3% (4/43), both P < 0.05]. In the distribution of clinical symptoms, the proportion of severe patients with chest distress/dyspnea was significantly higher than those in mild and general patients [66.7% (4/6) vs. 10.0% (1/10), 11.6% (5/43), both P < 0.05]. ② Laboratory examination index: the total number of white blood cell count (WBC), neutrophils count (NEU), C-reactive protein (CRP) in severe patients were higher than those in mild patients and general patients [WBC (×10 9/L): 7.21±4.35 vs. 5.85±1.69, 5.43±2.04; NEU (×10 9/L): 6.09±4.43 vs. 3.95±1.45, 3.54±1.83; CRP (mg/L): 16.00 (8.20, 46.43) vs. 5.00 (0.00, 16.13), 15.00 (3.13, 28.58)], the albumin (Alb) level in severe patients was lower than those in mild and general patients (g/L: 38.00±5.35 vs. 49.23±5.27, 39.81±2.15, both P < 0.05), while the hemoglobin (Hb) level in mild patients was higher than that in severe and general patients (g/L:155.2±12.1 vs. 141.3±6.8, 131.1±11.7, both P < 0.05). ③ Chest imaging: the CT manifestations of typical cases were single or multiple ground glass shadows. With the progress of the disease, the focus gradually increased, the scope gradually expanded, and multiple solid shadows of lung lobes were involved. ④ Treatment: all patients received at least 2 kinds of antiviral therapy, and the application rate of Interferon and Ribavirin in severe patients were higher than those in mild and general patients [100.0% (6/6) vs. 80.0% (8/10), 97.7% (42/43); 83.3% (5/6) vs. 0% (0/10), 20.9% (9/43); all P < 0.05]. ⑤ Prognosis: until March 6th 2020, 50 patients (84.8%) were discharged from the hospital after rehabilitation, and the remaining 9 patients were still under treatment, none deaths. Conclusions:The proportion of severe patients with chest distress/dyspnea is higher, the older the patients are and the more basic diseases are, the more likely they are to develop into severe type. High resolution chest CT could be considered for suspected cases or even fever patients, which may show the progress of the disease.

Objective To investigate the common types of fetal cardiac malformations and complicated malformations,and to assess the value of classifying on these types.Methods 3201 pregnant women were undergone with fetal echocardiography (FECG),239 fetuses of them were diagnosed to be suffered with congenital heart disease(CHD),and 8 cases were one of twins with abnormal heart confirmed by FECG.All new-births were examined by echocardiography within half year after their births.Results 155 complex CHD in 239 fetuses were diagnosed by FECG,in them the common malformations were in turn 59 cases with diagnosed univentricular heart,29 cases with double outlet right ventricle,19 with atrio ventricular septum defect,12 with tetralogy of Fallot or quinalogy of Fallot,11 with persistent truncus arteriosus,6 with right ventricular dysplasia syndrome,6 cases transposition of the great vessels.100 cases were induced labor,41 of them were comfirmed by pathology.16 fetuses were born,123 cases were being pregnanted or un-followed up.Conclusions Complex and multi-malformation were common in fetal cardiocascular abnormalities.Diagnosing rate of fetal CHD(FCHD) in our enroll fetuses was 7.47 ％,rate of complex CHD vs CHD was 64.85 ％.According different types of FCHD,able to be operated or not after birth,surgery methods,as well as prognosis evaluations,all FCHD cases were classified into three subtypes:curable type,curable palliative type and untreatable type.This newly viewpoint will help pregnant women and their family to make reasonable selection.

We established xenograft mouse models for studying human lung cancer by using an in vivo imaging system. We first transfected pGL4.17 (luc2/neo) plasmid into human non-small lung cancer A549 cells and screened cell lines stably expressing a luciferase reporter gene with G418. Then we analyzed the correlation of luciferase activity and cells number by in vitro bioluminescence. Furthermore, we compared cell growth characteristics by cell counting. We selected suitable clones and inoculated subcutaneously into nude mice or intravenously into SCID mice to construct lung cancer xenograft models. Using an in vivo imaging system, we monitored the growth and metastasis of the tumors. Finally, we verified the extents of tumorigenesis and metastasis by tissue sections with Hematoxylin and Eosin (HE) staining. In our study, we successfully established the xenograft mouse models for in vivo imaging with luciferase expressed lung cancer cells. These models provided convenient, sensitive, intuitive and stable tools for studying the mechanisms of lung cancer progression and development of anticancer drug.

Objective To evaluate the effects of the two methods of propaganda and education, conventional training method and that combined with hand contamination survey method, on the medical and nursing staffs' hand hygiene compliance. Methods From October 2017 to April 2018, all medical and nursing staffs in 6 Departments:General Surgery Ⅰ, General Surgery Ⅱ, Orthopedics Ⅰ, Orthopedics Ⅱ, Internal Medicine Ⅰ and Internal Medicine Ⅲin Cangnan Second People's Hospital receiving health education were divided into two groups; both groups received routine training, while in the observation group, on the basis of routine training, the hand hygiene pollution investigation training mode was added, In the combined training method, when the wrong hand hygiene mode occurred, the hand specimens were collected and the correct hand washing method was instructed on the spot, and then the following hand specimens were taken to investigate the contaminated condition. One month before the training, the real situations of hand hygiene compliance in the two groups were investigated. In the 1st month after the beginning of training, both groups were cultivated by conventional propaganda and training methods. From the second month to the sixth month, the observation group was additionally trained to investigate hand hygiene pollution situation on the basis of conventional propaganda and training methods. After 6 months, the compliance rates of hand hygiene in the two groups were observed. Results Before training, there was no significant differences in the compliance rate of hand hygiene in the observation group and the routine trainning group [37.14% (52/140) vs. 36.36% (48/132), P > 0.05]. The compliance rates of hand hygiene after 1, 2, 3 months of training in the observation group were 56.61% (77/136), 60.61% (80/132) and 61.20% (82/134), respectively, and those in the routine trainning group were 56.25% (72/128), 59.26% (80/135) and 58.70% (81/138), which were all significantly higher than those before the training (all P < 0.05), but there were no statistical significant differences between the two groups (all P > 0.05). From the 4th month to the 6th month after training, the compliance rates of hand hygiene in the observation group were significantly higher than those in the observation group [61.97% (88/142) vs. 49.23% (64/130), 62.50% (80/128) vs. 47.73% (63/132), 62.31% (81/130) vs. 46.03% (58/126)], the differences between the two groups being statistically significant (all P < 0.05). Conclusion The routine training combined with hand contamination investigation survey training for consecutive 3 months can nicely promote the improvement of hand hygiene compliance of medical and nursing staffs.

We hereby reported the clinical manifestations and genetic diagnosis of a rare case of congenital adrenal hyperplasia (CAH) caused by cytochrome P450 oxidoreductase ( POR ) gene mutation. The case was an 11-year-old girl presented with craniofacial and skeletal malformation such as a depressed nasal bridge, radiohumeral synostosis and camptodactyly in feet. Moreover, she was diagnosed with ambiguous genitalia, and her mother had obvious masculine features during pregnancy. Laboratory tests showed that the levels of peripheral blood progesterone, 17-hydroxyprogesterone and adrenocorticotrophic hormone (ACTH) had increased significantly, which were consistent with the symptom of CAH. Genetic testing revealed a complex heterozygous mutation in POR gene of maternally inherited c.744C>G (p.Tyr248Ter) and paternal inherited c.1370G>A (p.Arg457His). Therefore, she was diagnosed with cytochrome P450 oxidoreductase deficiency (PORD), which is a rare type of CAH. The patient received oral glucocorticoid therapy and underwent knee arthroplasty.

OBJECTIVETo optimize the methods for genetic detection and prenatal diagnosis of Duchenne muscular dystrophy (DMD).

METHODSDenaturing high-performance liquid chromatography (DHPLC), multiplex PCR (mPCR), sequencing and other molecular techniques were used in combination for molecular diagnosis of 8 cases diagnosed as DMD.

RESULTSAmong the 8 cases, 4 have carried large deletions, 3 have point mutations, among which 6 were of de novo type. Prenatal diagnosis were offered for 5 families, the results showed that none of the fetuses had carried large deletions or point mutations. The pregnancies had continued and healthy babies were born.

CONCLUSIONCombined use of short tandem repeat, DHPLC, mPCR and sequencing can improve the detection of DMD gene mutations. By establishing and optimizing genetic and prenatal diagnostic methods, accurate genetic counseling can be provided for families affected with DMD.
