Objective: To compare the time and spatial distribution of hepatitis C and HIV/AIDS cases and its correlation, in China from 2012 to 2017. Methods: Data on reported hepatitis C and HIV/AIDS cases was gathered from the Direct Reporting System of Infectious Diseases Information Network in China, 2012 to 2017 while annually collected provincial data was based on the date of review and current address. Correlation of the data was analyzed, using both simple correlation and linear regression methods. Results: The number of reported cases of hepatitis C remained stable in China, in 2012-2017, with the number of annual reported cases as 201 622, 203 155, 202 803, 207 897, 206 832 and 214 023, respectively. The number of reported cases on HIV/AIDS showed a steady growing trend, from 82 434, 90 119, 103 501, 115 465, 124 555 to 134 512. However, the numbers of hepatitis C and HIV/AIDS cases were in the same, top six provinces: Henan, Guangdong, Xinjiang, Guangxi, Hunan and Yunnan. Results from the simple correlation analysis indicated that there was a positive correlation (r>0.5, P<0.01) existed between the above-said two kinds of cases at the provincial level in China, in 2012-2017. Again, results from the linear regression analysis also showed that the correlation coefficient r(s) and year was strongly correlated (r=0.966) while r(s) had been linearly increasing with time. Conclusions: Our data showed that there were temporal and spatial correlations existed between the reported cases of hepatitis C and HIV/AIDS at the provincial level, suggesting that relevant prevention and control programs be carried out in areas with serious epidemics. Combination of the two strategies should be encouraged, especially on prevention and treatment measures related to blood transmission.

INTRODUCTIONThe subacute care unit in Tan Tock Seng Hospital (TTSH) was set up in May 2009. We examined its impact on the transitions at the nexus between hospital and community sectors, patients' discharge destination and functional performance.

MATERIALS AND METHODSWe studied patients admitted during the initial 6-month period (May to October 2009). Differences in demographics, length of stay (LOS), comorbidity and severity of illness measures, functional outcomes (modified Barthel Index (MBI)) according to discharge destinations were obtained. We also studied the impact of LOS on the geriatric department and the bill size over the pre- and post-subacute implementation periods.

RESULTSMajority of the subacute patients' hospital stay was in subacute care. Of these patients, 44.9% were discharged home, 24.2% to a slow stream rehabilitation (SSR) setting and 29.2% to nursing homes. 16.9% consisted of a subgroup of dementia patients requiring further behavioural and functional interventions, of which 50% managed to be discharged home. Functional gains were seen during subacute stay; with greatest gains observed in the SSR group. There were no differences in overall LOS nor total bill size (DRG-adjusted) for the geriatric medicine department during the first 6 months of operating this new subacute model compared with the prior 4-month period.

CONCLUSIONWe propose this subacute model of geriatric care, which allows right-siting of care and improved functional outcomes. It fulfills the role easing transitions between acute hospital and community sectors. In particular, it provides specialised care to a subgroup of dementia patients with challenging behaviours and is fiscally sound from the wider hospital perspective.

Cryptosporidium spp., ubiquitous enteric parasitic protozoa of vertebrates, recently emerged as an important cause of economic loss and zoonosis. The present study aimed to determine the distribution and species of Cryptosporidium in post-weaned and adult pigs in Shaanxi province, northwestern China. A total of 1,337 fresh fecal samples of post-weaned and adult pigs were collected by sterile disposable gloves from 8 areas of Shaanxi province. The samples were examined by Sheather's sugar flotation technique and microscopy atx400 magnification for Cryptosporidium infection, and the species in positive samples was further identified by PCR amplification of the small subunit (SSU) rRNA gene. A total of 44 fecal samples were successfully amplified by the nested PCR of the partial SSU rRNA, with overall prevalence of 3.3%. The average prevalence of Cryptosporidium infection in each pig farms ranged from 0 to 14.4%. Species identification by sequencing of SSU rRNA gene revealed that 42 (3.1%) samples were Cryptosporidium suis and 2 (0.15%) were Cryptosporidium scrofarum. C. suis had the highest prevalence (7.5%) in growers and the lowest in breeding pigs (0.97%). C. suis was the predominant species in pre-weaned and adult pigs, while C. scrofarum infected pigs older than 3 months only. A season-related difference of C. suis was observed in this study, with the highest prevalence in autumn (5.5%) and the lowest (1.7%) in winter. The present study provided basic information for control of Cryptosporidium infection in pigs and assessment of zoonotic transmission of pigs in Shaanxi province, China.

OBJECTIVES: This pilot study tested the effectiveness of a brief alcohol-related intervention delivered by the social media app WeChat to teach about ethanol-induced facial flushing and increase the willingness of students who see another student flushing to suggest that he or she should reduce or stop drinking. In the context of Chinese drinking culture, it is sometimes socially difficult to refuse a drink, even when experiencing physical discomfort, such as flushing. METHODS: Classrooms of students in a medical university in China were randomly assigned to the intervention or control group. Students in the intervention group were invited to view 3 alcohol education lessons on WeChat during a 2-week period. A pretest and posttest before and after the 2-week period assessed changes in students’ willingness to intervene if they saw someone flush while drinking. Data were collected about students’ alcohol use and their ratings of the lessons. RESULTS: Mixed-design analysis of variance yielded a significant time-by-treatment interaction effect on the variable of willingness to suggest that a flushing person stop or slow down their drinking, and the change was significant between the intervention and control groups. One-way analysis of covariance yielded a significant treatment effect at the posttest, after controlling for the pretest score. Students rated the lessons above the midpoint of the scale for being informative, interesting, and useful. CONCLUSIONS: The pilot study showed that a brief alcohol-related intervention delivered by WeChat could produce a measurable positive change in the willingness of university students to suggest that a student who flushes should stop drinking. This pilot study also suggested improvements for future lessons and evaluation design.

Objective: To describe the characteristics of newly reported HIV/AIDS cases via non-marital or non-commercial heterosexual transmission and to find out the relative factors in Hangzhou, from 2015 to 2017. Methods: Data were collected through the national HIV/AIDS comprehensive control and prevention data system. Study subjects would include those reported HIV/AIDS cases who were residents of Hangzhou and were infected via non-marital heterosexual transmission, between January 1, 2015 and December 31, 2017. Demographic characteristics and behavioral information were collected. χ(2) test was used to compare different characteristics of the non-married heterosexual transmission subjects. Logistic regression was used to assess factors that associated with non-marital but non-commercial HIV heterosexual transmission with SPSS. 20 software used to analyze statistically. Results: Non-marital HIV heterosexual transmission accounted for 38.03% (1 393/3 663) of the total new reported HIV/AIDS cases in 2015-2017. Out of the 1 393 HIV/AIDS cases, those infected through non-marital but non-commercial heterosexual transmission accounted for 50.83% (708/1 393), and those through non-martial commercial transmission was accounted for 49.17% (685/1 393). Male to female ratio was 3.51 ∶ 1 (1 084/309). Male HIV cases reported that their major way of infection was via non-marital commercial transmission (670/1 084, 61.81%), while female patients reported the way was via non-marital non-commercial (294/309, 95.1%). Results from multivariate logistic analysis showed that the related risk factors and ORs for non-marital but non-commercial transmission appeared as: female (aOR=48.25, 95%CI: 26.94- 88.44),<30 year olds (aOR=2.43, 95%CI: 1.31-4.51), 30-39 year olds (aOR=1.92, 95%CI: 1.11- 3.33), 40-49 year olds (aOR=1.80, 95%CI: 1.08-3.00), married or unmarried (vs. divorced or widowed, aOR=1.57, 95%CI: 1.10-2.24; aOR=1.78, 95%CI: 1.15-2.78), high school and above of education level (vs. primary school and under of education level, aOR=1.82, 95%CI: 1.18-2.80), administrative officers or employee (vs. farmers, aOR=2.03, 95%CI: 1.04-1.91). Number of non- marital partners less than 5 (vs. number of non-marital partners more than 5, aOR=10.65, 95%CI: 6.41-17.42). Conclusions: HIV/AIDS cases with non-marital heterosexual transmission accounted for considerable proportion regarding the HIV transmission in Hangzhou from 2015 to 2017. Differences were found in the following factors as non-marital and non-commercial heterosexual transmission with diverse gender, age, marital status, educational level and occupation among of the HIV/AIDS patients.

AIMTo determine the effects of the functional domain of saposin C (neurotrophic peptide [NP]) on androgen receptor (AR) expression and transcriptional activity.

METHODSWe constructed DNA vectors expressing NP or a chimeric peptide of the viral TAT transduction domain and NP (TAT-NP) using gene cloning technology. The effects of ectopic expression of NP or TAT-NP on cell growth were examined by 3-(4, 5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay. Reverse transcription-polymerase chain reaction (RT-PCR), Western blot, transient transfection and reporter gene assays were used to determine the effects of NP on AR expression and activation.

RESULTSNP stimulated proliferation of androgen responsive LNCaP cells in the absence of androgens. RT-PCR and Western blot analyses showed that ectopic expression of NP resulted in induction of AR gene expression, and that the NP-stimulated expression of AR could be synergistically enhanced in the presence of androgens. Furthermore, reporter gene assay results showed that NP could enhance AR transactivation by increasing androgen-inducible gene reporter activity.

CONCLUSIONWe provided evidence that ectopic expression of saposin C-originated NP could upregulate AR gene expression and activate the AR transcriptional function in an androgen-independent manner in prostate cancer cells.

Purpose: Optical coherence tomography (OCT) has the potential for in vivo clot composition characterization in difficult mechanical embolectomy cases. We performed an in vitro study to determine the OCT characteristics of red blood cells (RBCs) and fibrin rich clots. Materials and Methods: Analogues of 5 compositions of clots (5% to 95% RBCs from Group A to E) were created from human blood. The blood mixture was injected into the bifurcation of a 3D printed bifurcated silicone tube. The OPTISTM Integrated System (St. Jude Medical Inc.) was used to identify the magnitude of OCT signals from different compositions of clots. Martius Scarlett Blue trichrome (MSB) staining was performed to confirm the composition of RBCs and fibrin in each clot. Results: Group A and B showed less signal attenuation (less than 30%) from its surface to the inside, which indicated high penetration (low-back scattering). Group C indicated intermediate signal attenuation (60%) from its surface to inside the clots, in which signals were found even at the periphery of the clot. Group D and E were superficially signal rich with more signal attenuation (more than 80%) from its surface to the inside indicating low penetration (high-back scattering). Signal-free shadowing was shown in 3 clots in Group E. MSB staining indicated color change (from red in fibrin-rich clots to yellow in RBC-rich clots). Conclusion Different compositions of clots can be assessed using OCT. Fibrin-rich clots have homogeneous signals with high penetration, while RBC-rich clots can be recognized as superficially signal rich with low penetration.

OBJECTIVE： To explore the method for the development and implementation of drug abuse monitoring in medical institutions， and to provide reference for drug abuse monitoring in medical institutions. METHODS： Our hospital （the affiliated hospital of Binzhou medical college） had established the corresponding drug abuse monitoring mode from the two aspects of real-time monitoring and retrospective analysis， supplemented by relevant management measures， defined the content of drug abuse monitoring in medical institutions， and finally evaluated the implementation effect through the effective reporting quantity of drug abuse information， etc. RESULTS & CONCLUSIONS： The main contents of drug abuse monitoring in our hospital included the establishment of drug abuse monitoring management group， the improvement of drug abuse monitoring system and the sorting out of drug monitoring catalogue； the real-time drug abuse monitoring mode was established through timely reporting drug abuse information by medical， nursing and pharmaceutical personnel in daily diagnosis and treatment activities； at the same time， the retrospective analysis model of drug abuse was established by analyzing the relevant drug use data regularly through the hospital information system， paying attention to the key groups of key departments， and mining drug abuse information； a series of auxiliary management measures were taken， such as strengthening training and publicity， and establishing reward and punishment mechanism. Since the monitoring work was started in 2016， the effective number of drug abuse information reported in 2016-2018 was 38， 126 and 237 respectively， and through the monitoring， it was found that the elderly women over 60 years old （69.83％） were abusing in iatrogenic sedative hypnotic drugs. The development of drug abuse monitoring in hospital can collect drug abuse status， behavior characteristics and relevant information timely and effectively， analyze local drug abuse trends， find drug abuse risks， and provide basis for drug control of narcotics and psychotropic substances supervision.

Objective: To investigate the clinicopathological features of glomuvenous malformation (GVM). Methods: Thirty-one cases of GVM diagnosed at the Henan Provincial People's Hospital from January 2011 to December 2021 were collected. Their clinical and pathological features were analyzed. The expression of relevant markers was examined using immunohistochemistry. The patients were also followed up. Results: There were 16 males and 15 females in this study, with an average age of 11 years (range, 1-52 years). The locations of the disease included 13 cases in the limbs (8 cases in the upper limbs, 5 cases in the lower limbs), 9 cases in the trunks, and 9 cases in the foot (toes or subungual area). Twenty-seven of the cases were solitary and 4 were multifocal. The lesions were characterized by blue-purple papules or plaques on the skin surface, which grew slowly. The lumps became larger and appeared to be conspicuous. Microscopically, GVM mainly involved the dermis and subcutaneous tissue, with an overall ill-defined border. There were scattered or clustered irregular dilated vein-like lumens, with thin walls and various sizes. A single or multiple layers of relatively uniform cubic/glomus cells were present at the abnormal wall, with scattered small nests of the glomus cells. The endothelial cells in the wall of abnormal lumen were flat or absent. Immunohistochemistry showed that glomus cells strongly expressed SMA, h-caldesmon, and collagen IV. Malformed vascular endothelial cells expressed CD31, CD34 and ERG. No postoperative recurrence was found in the 12 cases. Conclusions: GVM is an uncommon type of simple venous malformation in the superficial soft tissue and different from the classical glomus tumor. Morphologically, one or more layers of glomus cells grow around the dilated venous malformation-like lumen, which can be combined with common venous malformations.
