Objective To study the frequencies and therapeutic effect of anxious and depressive disorders in patients with stroke.Methods 86 patients were assessed with Hamilton anxiety scale(HAMA)and Hamilton depression scale(HAMD).The patients with anxious and depressive disorders were treated with antianxiety agents and antidepressants such as benzodiazepines,fluoxetine,and venlafaxine.Results In the 86 patients,the frequencies of anxious and depressive disorders were 48\^8%,38\^4%,respectively,recovery rates of treatment were 83\^3%,75\^8%,respectively,in which the scores of HAMA and HAMD after treatment were much less than that before treatment(P

Objective To investigate the effective and inexpensive therapy to partial denture arches with seriously interlaced occlusion. Methods Occlusal reconstructions with fixed and removable prosthesis were taken to cure partial denture arches with seriously interlaced occlusion. Masticatory efficiency was measured and X-rays of Schillers position were taken before and after therapy. Results After therapy masticatory efficiency was raised. And the function of TMJ was better. Conclusion Occlusal reconstruction with fixed and removable prosthesis is an effective way to cure partial denture arches with seriously interlaced occlusion.

Objective To optimize the proportion of three transdermal penetration enhancers on transdermal absorption of ligustrazine hydrochloride.Methods Permeation tests in vitro through BALB/c nude mouse skin in two compartment diffusion cells were performed to study the effect of synthetic borneol,menthol,and Azone on trandermal absorption of ligustrazine hydrochloride by changing their concentrations,and uniform design method was used to determine the penetration coefficient of ligustrazine hydrochloride and optimize the proportion of three transdermal penetration enhancers.ResultsThe optimal proportion and contents of synthetic borneol,menthol,and Azone were 1.5%∶1.5%∶1.5%(15 mg/mL∶15 mg/mL∶15 mg/mL),the real penetration coefficient of ligustrazine hydrochloride was 69.575 ?g/(h?cm2),while the theoretical penetration coefficient was 69.749 ?g/(h?cm2).Conclusion Uniform design method is an effective way to optimize the proportion of three transdermal penetration enhancers on trandermal absorption of ligustrazine hydrochloride.

OBJECTIVE:To observe the effect of different concentration of borneol nasal drops on the vasopermeability of nasal mucosa and the cerebral vessels.METHODS:Guinea pigs were divided into5groups,i.e.borneol group in3different concentrations(0.5%,1.0%and2.0%),histamine group and liquid paraffin group.Guinea pigs were injected i.v with2%evans blue(EB)after administration with nasal drops,which were then put to death10min later;the nasal mucosa and brain tissue of which were obtained and the EB contents in which were determined.RESULTS:Compared with the liquid paraffin group,the EB contents in the nasal mucosa and brain tissue in the borneol groups were higher(P

Objective:To discover the epidemiological characteristics and clinical manifestations of Nontyphoidal Salmonella(NTS) infection in children suffering from diarrhea in Guangzhou, and to provide references for the prevention and treatment of salmonella infection. Methods:A total of 570 diarrhea children and 296 non-diarrhea controls were collected with stratified sampling from three districts of Guangzhou Women and Children′s Medical Center from January 2019 to December 2019. Through bacterial culture, corresponding colonies were selected and Salmonella diagnostic serum was applied for preliminary serum diagnosis, and then systemic biochemical method was adopted for diagnosis. A structured questionnaire was conducted to record the demographic information and clinical symptoms from each subject. Results:The detection rate of NTS was 6.67% (38/570 cases, 95% CI: 4.90%-9.02%) in children with diarrhea, and 1.01% (3/296 cases, 95% CI: 0.34%-2.93%) in children without diarrhea. There were statistically differences in NTS detection rate between children with diarrhea and the control ( χ2=13.805, P<0.05, OR=6.976, 95% CI: 2.135-22.796). There were no significant differences in NTS detection rate between male and female children with diarrhea ( χ2=0.395, P>0.05, OR=1.254, 95% CI: 0.619-2.541). The detection rate of NTS was 5.30% (22/416 cases, 95% CI: 3.52%-7.88%) in children younger than 2 years old, and was 10.40% (16/154 cases, 95% CI: 6.50%-15.21%) in children over 2 years old. There were statistically differences ( χ2=4.700, P<0.05, OR=2.076, 95% CI: 1.060-4.068) between the younger and the older groups.The detection rate of NTS was 5.40% (25/460 cases, 95% CI: 3.70%-7.89%) for children with diarrhea in outpatient department and 11.80% (13/110 cases, 95% CI: 7.04 %-19.18%) for children with diarrhea in inpatient department, with statistically significant differences ( χ2=5.813, P<0.05, OR=2.332, 95% CI: 1.152-4.721). The detection rate of NTS diarrhea in children was 4.60% (10/217 cases, 95% CI: 2.52%-8.28%) in spring, 8.50% (12/141 cases, 95% CI: 4.93%-14.29%) in summer, 9.60% (15/144 cases, 95% CI: 6.41%-16.48%) in autumn and 1.50% (1/168 cases, 95% CI: 0.11%-3.30%) in winter, respectively, with statistically differences among the four seasons( χ2=9.404, P<0.05). There were significant differences in most common clinical symptoms of fever, vomiting, abdominal pain, bloody stool and pasty stool between NTS positive and negative children(all P<0.05). Salmonella enteritis is the main type, and Salmonella typhimurium is the second type. Conclusions:NTS is one of the most important bacterial pathogens and leads to diarrhea in children in Guangzhou city, without differences in gender.Children over 2 years old are more likely to suffer from NTS infection.High incidence is in autumn.The most common clinical symptoms include fever, vomiting, abdominal pain, bloody stool and pasty stool. Salmonella enteritis is the main type, and Salmonella typhimurium is the second type.Laboratory tests can provide references for the diagnosis and treatment of NTS-related diarrhea.

Objective To establish a method of quick three-dimensional (3D) reconstruction of pubic symphysis based on magnetic resonance imaging. Methods The pelvis images of adult male were generated on a 3.0 T scanner using a T1 Gradient Echo FLASH-3D (T1- FL3D) sequence and imported the images into medical image control system. Segmentation of binaryzation threshold was conducted and pelvic soft tissue image was extracted by regional growth, 3D structure model of pubic symphysis was obtained by Boolean operation. The 3D structure model of pubic symphysis was established by the noise reduction of reverse engineering software. And compared with the 3D reconstruction model pubic bone CT scan. Results The morphological characters of the MRI pubic symphysis 3D model, such as the ridges and furrows on the symphysial surface, lower extremity, dorsal margin (beveling), margin (beveling) and pubic tubercle, were highly consistent with the morphological characters of the 3D model established by CT scan. Conclusion MRI scan can be used to reconstruct the 3D structure of pubic symphysis quickly and effectively, and it can provide a safe radiation-free 3D visualization imaging technique for forensic age estimation for the living.

Standardized residency training is the only way for medical students to grow into clin-icians. At present, the number of under training residents in China has reached 190000 (excluding special-ized degree graduate students). It is very important to manage each stage of this training well, which is an guarantee for improving the effect of standardized training. The residents who attend the training are com-posed of "unit personnel" and "intra-industry social personnel", and after standardized and homogenized training, the two types of students have officially become the new force in the medical industry after passing the final examination. In order to do a good job in the management of standardized residency training, to achieve fine management at all stages , this paper focuses on the differences between the two types of students, analyzes in detail the characteristics of these two types of students in the recruitment, training and welfare guarantee stages. "Unit personnel" are given the security, supervision and containment of the origi-nal unit, while due to the pressure of job-hunting and the uncertainty of future welfare, "intra-industry so-cial personnel" are equipped with more initiative. Based on advanced management experience in Beijing,Shanghai, Sichuan and Tianjin, this paper aims to summarize the key points in management of the two types of students in training, propose countermeasures to the difficulties in management, innovative management solutions, and provide reference for the optimization management of standardized residency training.
