Objective:To investigate the impact of China's Mental Health Law on the work of psychological counseling in colleges and universities, and to explore ways to improve the law. Methods: Totally 12 heads of college and university counseling centers in Beijing were conducted with semi-structured interviews. The average age of the interviewees was (40 ±7) years old, with master or doctor degrees in psychology or related disciplines. The method of content analysis was used to analyze the interviewees' understanding of the " Mental Health Law". Results: All of the 12 interviewees had gained some understanding of the "Mental Health Law", and accordingly amended the regulation of their counseling centers. Also, interviewees suggested the positive and negative impacts brought by the law, such as enhancing practitioners' legislative sense, clarifying their responsibilities and boundaries as college and university counseling, as well as difficulties to distinguish psychotherapy and psychological counseling, ambiguity in the legality of working with students who were diagnosed with mental disorders. Moreover, interviewees threw out suggestions on improving the law from the aspect of industry standard, supervision department and vocational qualification. Conclusion: The execution of "Mental Health Law" improves practitioners' legislative sense, clarifies their responsibility. Nevertheless, it does not clearly distinguish psychotherapy from psychological counseling, and be lack of regulation on the psychological counseling industry.

Objective To screen the prevalence and related risk factors of minor hallucinations(MH)in newly diagnosed Parkinson's disease(PD).Methods From November 2018 to December 2022,274 newly diagnosed patients with untreated PD were enrolled in the PD Clinic of Brain Hospital Affiliated to Nanjing Medical University.According to the score of item 2 of the unified PD rating scale Ⅰ(UPDRSⅠ),the PD patients with MH were selected(MH group,score≥2).The patients matched in age,sex,education and course of disease level were screened in non-MH PD patients(NMH group,score = 0).Cognitive function,depressive symptoms,anxiety symptoms,sleep quality,non-motor symptoms,rapid eye movement sleep disorder(RBD)symptoms,activities of daily life,motor function and disease severity were evaluated with appropriate scales.The differences between two groups were compared,and the risk factors of MH in PD patients were analyzed by univariate and multivariate progressive Logistic regression.Results Among the 274 newly diagnosed PD patients,11 cases(4.01%)had MH.Compared with those in NMH group(22 cases),MH group had higher Hamilton depression scale(HAMD)scores,higher Hamilton anxiety scale(HAMA)scores,higher PD non motor symptoms(PDNMS)scores and higher RBD scores(all P＜0.05).Univariate Logistic regression analysis showed that high HAMD scores,high HAMA scores,high PDNMS scores and high RBD scores were risk factors for MH in PD patients(all P＜0.05).Multivariate Logistic regression analysis showed that high HAMD score(OR =1.182,95%CI:1.004-1.392,P =0.045)and high RBD score(OR =4.448,95%CI:1.066-18.557,P =0.041)were independent risk factors for MH in PD patients.Conclusions MH may occur in newly diagnosed PD patients with probability.Depression and RBD are independent risk factors for MH in PD patients.Attention should be paid to screening patients like this and early intervention measures should be taken.

Objective: The clinical data involving pediatric dental trauma and the features of dental trauma in children were summarized to provide a reference for the treatment and prevention of dental trauma. Methods: A retrospective analysis was performed on 644 children with dental trauma who were admitted to the Department of Children s Stomatology, Stomatology Hospital of Xiamen Medical College from January to December 2022. Descriptive methods were used to analyze the general demographic characteristics of the children and clinical features of dental trauma. Results: The characteristics of the children with dental trauma were as follows: male-to-female ratio, 2.16∶1; mean age, (6.73±3.42) years; most frequently affected age groups, 2-4 and 7-9 years (26.09%, 33.85%); most frequent season for dental trauma, spring (27.61%) and autumn (28.55%); least common season for dental trauma, summer(18.88%); most frequent time of day for dental trauma, evening (51.47%); least common time of day for dental trauma, morning (2.68%); >24 h elapsed from dental trauma-to-treatment (42.08%); most common type of injuries; simple tooth hard tissue and pulp injury in permanent teeth(65.25%) and simple periodontal tissue injury of primary teeth( 53.35 %); most likely teeth involved, maxillary central incisors (80.10%); and number of affected teeth, 1-2. Conclusions The incidence of dental trauma in children has common features, but most children do not see a dentist timely after dental trauma occurs. Educating parents of children with dental trauma should be encouraged to reduce the incidence of dental injury.

Objective:To investigate the therapeutic effect of reverse proximal segment dorsal flap of radial digital artery of the thumb in repairing thumb tip defects.Methods:A retrospective case series study was conducted to analyze the clinical data of 56 patients with thumb tip defects admitted to Renqiu People 's Hospital from February 2010 to October 2020. There were 37 males and 19 females，aged 17-66 years［（37.8±12.2）years］. The injury on the right side was observed in 35 patients and on the left side in 21 patients. All of them were thumb tip defects with exposed distal phalanx. Dimension of skin defects was 2.9 cm×1.8 cm-3.3 cm×2.6 cm.The reverse proximal segment dorsal flap of thumb radial digital artery was used，with the dorsal digital nerve sutured with the proper digital nerve. The donor site was repaired with free skin graft from the ulnar side of the affected forearm. The time of flap harvesting，operation time and healing of the flap were measured. At the last follow-up，the shape，texture，sensory recovery and complications of the flap were observed. One month after operation and at the latest follow-up，the upper limb function evaluation standard set up by hand surgery branch of Chinese Medical Association and Vancouver Scar Scale（VSS）score were used to evaluate the recovery of sensory function of the flap and scar formation of the donor sites，respectively. Results:All patients were followed up for 6-26 months［（13.2±6.4）months］. The time of flap harvesting ranged from 20 to 35 minutes［（26.0±5.3）minutes］. The operation time was 1-2 hours［（1.3±0.3）hours］. Blisters appeared at the distal end of the flap in 2 patients after operation，but they were not treated. After 7 days，the blisters subsided and the flaps survived. The other flaps survived successfully. The donor sites healed by first intention. At the last follow-up，the flaps showed relatively cosmetic appearance，similarities in texture，elasticity and color to the surrounding area and good sensory recovery，without scar contracture and dystrophy of interphalangeal joint. According to the upper limb function evaluation standard set up by hand surgery branch of Chinese Medical Association，56 patients exceeded S3 grade compared to none at postoperative 1 month（ P<0.01），and the VSS score was 3-7 points［（5.0±1.4）points］compared to 6-12 points［（8.8±1.5）points］at postoperative 1 month（ P<0.01）. The donor site left a linear scar，which had no significant effect on its shape and function. Conclusion:The reverse proximal segment dorsal flap of the radial digital artery of the thumb can be used to repair thumb tip defects，for it has advantages of easy operation，a high survival rate as well as good appearance and sensory function recovery，with less damage to the donor area.

Objective:To report our clinical efficacy of pedicled transplantation of proximal thumb dorsal transverse flap to repair tissue defects at thumb pulp and fingertip.Methods:From February 2010 to November 2020, 97 patients with tissue defects at thumb pulp and fingertip were treated by pedicled transplantation of proximal thumb dorsal transverse flap at Department of Orthopedics, People's Hospital of Renqiu. They were 55 men and 42 women, aged from 17 to 66 years (average, 41.3 years). Altogether 55 right and 42 left sides were affected. The size of soft tissue defects ranged from 2.8 cm×1.8 cm to 3.9 cm×2.8 cm. Postoperatively, flap survival, shape, color and sensory recovery at the recipient area were observed; wound healing, function and complications at the donor site were also observed.Results:All the 97 flaps survived and all the wounds healed at the first stage. Blisters appeared at the distal end of the flap in only 2 cases but subsided 7 days after operation with no special treatment and the flaps survived smoothly. All the skin grafts at the donor site survived uneventfully. The 97 patients were followed up for 6 to 26 months (average, 10.7 months). Their flaps were not swollen, finger abdomen was full, finger appearance satisfactory, and finger feeling recovered well. The two-point discrimination at the last follow-up ranged from 4 to 11 mm (average, 7.6 mm). By the trial criteria for assessment of upper limb function suggested by Hand Surgery Society of Chinese Medical Association, sensory function of the affected finger was assessed as S 4 in 21 cases and as S 3+ in 76 cases at the last follow-up. No scar contracture was observed at the donor site and no movement restriction at the interphalangeal joint. Conclusion:Proximal thumb dorsal transverse flap is a reliable choice for reconstruction of complex tissue defects at thumb pulp and fingertip because of the advantages of easy harvest, constant vascular anatomy, full appearance and good sensory function at the recipient site, and limited damage to the donor site.

Drug therapy is a common method to cure diseases and relieve symptoms.The value of patient-reported outcome(PRO)in evaluating the effect of drug therapy has been increasingly paid attention.The PRO scale is a standardized questionnaire,which can scientifically evaluate the experiences and subjective effects of drug use from a patient-centered perspective,and help patients and clinicians make more reasonable medication decisions.By reviewing and sorting out relevant global literature,this paper found that the content of the PRO scales relevant to drug therapy focused on five fields:"medication satisfaction""medication adherence""drug treatment burden""medication-related quality of life"and"adverse drug reactions".This paper described the basic information,measurement characteristics and application of common scales in recent years respectively,and summarized and analyzed the problems and enlightenment of scale development,aiming to provide theoretical reference for the selection,application and development of PRO scales.

Objective:To investigate the correlation between gender, age, blood collection time, season and changes in cTnT concentration.Methods:In this study, 3548 patients (non-cardiovascular diseases) in Zhongshan Hospital of Fudan University were selected from 1 January to 31 December 2019. The basic data of the patients were collected, including gender, age, time of blood collection, medical history, clinical diagnosis, and results of cTnT testing. 1 840 males and 1 708 females were finally enrolled, with an age distribution of 65 (53, 75) years. The distribution of the data was assessed using the Kolmogorov-Smirnov (K-S) test, where non-normally distributed data were expressed as M( Q1, Q3). The Mann-Whitney U-test was used to compare cTnT concentrations between men and women, and to analyse the influence of gender on cTnT results. The Kruskal-Wallis test was used to compare cTnT levels between gender groups, to analyse the correlation between different times of blood collection, seasons, and other factors and cTnT concentrations. Result:cTnT concentrations increased with age in both males and females over the age of 60 years. cTnT levels were highest in individuals over the age of 90 years (0.028 ng/ml in males and 0.018 ng/ml in females). cTnT levels were higher in males (0.012 ng/ml) than in females (0.009 ng/ml) in all age groups ( H=6.340, P<0.01). The concentrations of cTnT varied at different time points of blood collection. In both males and females, cTnT concentrations reached a maximum at 8:00 and 13:00 (0.013 ng/ml and 0.012 ng/ml, respectively). Analysis of the physiological effect of season on cTnT secretion showed that cTnT levels were generally higher in spring and winter(0.012 ng/ml) than in summer and autumn(0.010 ng/ml). Conclusions:cTnT concentration is influenced by gender, age, time of blood collection and season. When analysing cTnT results in clinical practice, the gender and age of the individual should be taken into account, as well as the time point of blood collection and seasonal factors.
