Objective To study the clinical features of primary biliary cirrhosis (PBC) in order to improve the clinical diagnosis. Methods Clinical data of fifty patients with PBC were retrospectively studied. The clinical features, results of laboratory tests, pathological findings of all the fifty patients were analyzed. Results forty-four patients were female (88%), and the mean age was 44.94?12.33 years at the time when definite diagnosis was made. The most frequent symptoms complained were fatigue (34/50, 68%), anorexia (24/50, 48%) and pruritus (13/50, 26%).The major signs included jaundice (32/50, 64%), splenomegaly (24/50, 48%) and liver palms (14/50, 28%). Serum alkaline phosphatase (ALP) and r glutamyl transpeptidase (r-GT) levels were markedly elevated in most patients, and the levels of ALP and GGT declined during the advanced stage. The levels of ALT and AST were elevated slightly. The total level of serum bilirubin was elevated in thirty-two patients (64%). Positive anti-mitochondrial antibody (AMA)/AMA-M2 were found in forty-one patients (82.0%). Pathological examination was done in 32 patients, it was shown that 28 patients (87.5%) were in early stage and 4 patients (12.5%) in advanced stage. Conclusion PBC occurs mainly in middle- and old aged women. The main clinical manifestations are fatigue, anorexia and pruritus. The elevated level of ALP, r-GT and positive AMA/AMA-M2 may be crucial to diagnosis of PBC.

Objective:To observe the effect of well-designed board sanding training on the upper extremity motor functioning of hemiplegic stroke survivors.Methods:Sixty stroke survivors with hemiplegia were randomly divided into an observation group (30 cases) and a control group (30 cases). All received conventional rehabilitation. The observation group′s training involved intelligent board sanding, while the control group′s training involved traditional sanding.Results:After the treatment, significant improvement was observed in the Fugl-Meyer upper extremity scores, modified Barthel index scores and reported shoulder pain in both groups, with the observation group′s averages significantly better than those of the control group. After the intervention, the average scores of both groups on the modified Ashforth scale had also improved significantly.Conclusions:Supplementing conventional rehabilitation treatment with intelligent board sanding can significantly improve upper extremity motor function and ability in the activities of daily living of stroke survivors with hemiplegia while somewhat relieving shoulder pain. The effect is better than with traditional board sanding.
4.Sexual orientation and characteristics of sexual behaviors among 200 HIV positive male college students in Beijing
Chinese Journal of School Health 2022;43(7):999-1002
Objective:
To understand sexual orientation and characteristics of sexual behaviors related with HIV infection among HIV positive male college students in Beijing and to provide suggestions for development of sexual health education and HIV prevention strategy for student population.
Methods:
HIV positive male college students diagnosed from 2016 to June 30, 2019 in Beijing were recruited. Questionnaire was used to retrospectively investigate sexual orientation and characteristics of sexual behaviors before HIV infection. Behaviors related to HIV infection were compared between absolutely homosexual and others sexual orientation.
Results:
The average age of male students firstly identified to be HIV positive was (22.18±2.70) years old, 61.5%(123) of them were undergraduate, 69.5%(139) were not registered permanent residency in Beijing, 38.5%(77) of their interviewed sexual partners were from online chat and 83.0%(166) had homosexual behaviors. Sexual orientation score analysis showed that 50.0% of the participants self identified as exclusively homosexual. Compared with other sexual oriental group, exclusively homosexual group had lower mean age of their HIV infection firstly identified( t =2.77, P =0.01), higher rate of Rush use, firstly insertive sexual behavior with male, firstly insertive sexual behavior before 18 years old, sexual partners more than three persons, having regular partners, nonpersistent use of condom, being diagnosed of sexual transmitted disease and the frequency of homosexual behaviors more than 1 time per month ( χ 2=5.15,28.06,4.16,5.34,5.89,7.39,6.68, P <0.05). Rush users had higher rate of STD diagnosis than non users in exclusively homosexual group ( χ 2=6.26, P =0.01).
Conclusion
Risky sexual behaviors associated with HIV infection were higher in exclusively homosexual group then other sexual orientation groups among HIV positive male college students. Family and school should concern with sexual health education byreinforcing health education via network media to improve college students’ awarenees on HIV/AIDS.

OBJECTIVES:
To provide reference basis for reducing the mortality for children under 5 years old and promote the healthy development, the mortality for children under 5 years old and the main causes for death in Liuyang City from 2013 to 2020 are analyzed.
METHODS:
The data of 725 cases of death for children under 5 years old in Liuyang City from 2013 to 2020 were collected.The causes and difference of death among the children were analyzed retrospectively by descriptive statistic methods.
RESULTS:
There were a total of 144 516 live births in Liuyang City from 2013 to 2020. The mortality for children under 5 years old was 5.01‰, for infants was 3.39‰, and for newborns was 1.63‰. The male child mortality was 5.28‰, and the female child mortality rate was 4.72‰, with significant difference (P>0.05). The mortality for children under 5 years old was seasonal fluctuation, without significant difference among seasons (P>0.05). For the past 5 years, the top 3 causes for death among children under 5 years old were preterm birth and low birth weight, congenital heart disease, and pneumonia. Before death, 341 cases (47.04%) were treated in provincial hospitals, 198 cases (27.31%) in county-level hospitals, 56 cases (7.72%) in village-level hospitals, and 130 cases (17.93%) were not treated.
CONCLUSIONS
The mortality for children under 5 years old in Liuyang City is gradually reduced in the past 5 years. The main causes for death are premature birth and low birth weight, congenital heart disease and pneumonia. We should develop healthy education, improve the rate of prenatal diagnosis, promote the construction of obstetrics and paediatrics, and fundamentally reduce the mortality for children under 5 years old.

Coronavirus disease 2019 (COVID-19) has continued to spread globally since late 2019, representing a formidable challenge to the world's healthcare systems, wreaking havoc, and spreading rapidly through human contact. With fever, fatigue, and a persistent dry cough being the hallmark symptoms, this disease threatened to destabilize the delicate balance of our global community. Rapid and accurate diagnosis of COVID-19 is a prerequisite for understanding the number of confirmed cases in the world or a region, and an important factor in epidemic assessment and the development of control measures. It also plays a crucial role in ensuring that patients receive the appropriate medical treatment, leading to optimal patient care. Reverse transcription-polymerase chain reaction (RT-PCR) technology is currently the most mature method for detecting viral nucleic acids, but it has many drawbacks. Meanwhile, a variety of COVID-19 detection methods, including molecular biological diagnostic, immunodiagnostic, imaging, and artificial intelligence methods have been developed and applied in clinical practice to meet diverse scenarios and needs. These methods can help clinicians diagnose and treat COVID-19 patients. This review describes the variety of such methods used in China, providing an important reference in the field of the clinical diagnosis of COVID-19.
