Objective To analyze the genetic subtypes of human immunodeficiency virus (HIV) and the prevalence of pretreatment drug resistance in the newly reported HIV-infected men in Guangxi. Methods The stratified random sampling method was employed to select the newly reported HIV-infected men aged≥50 years old in 14 cities of Guangxi from January to June in 2020.The pol gene of HIV-1 was amplified by nested reverse transcription polymerase chain reaction and then sequenced.The mutation sites associated with drug resistance and the degree of drug resistance were then analyzed. Results A total of 615 HIV-infected men were included in the study.The genetic subtypes of CRF01_AE,CRF07_BC,and CRF08_BC accounted for 57.4% (353/615),17.1% (105/615),and 22.4% (138/615),respectively.The mutations associated with the resistance to nucleoside reverse transcriptase inhibitors (NRTI),non-nucleoside reverse transcriptase inhibitors (NNRTI),and protease inhibitors occurred in 8 (1.3%),18 (2.9%),and 0 patients,respectively.M184V (0.7%) and K103N (1.8%) were the mutations with the highest occurrence rates for the resistance to NRTIs and NNRTIs,respectively.Twenty-two (3.6%) patients were resistant to at least one type of inhibitors.Specifically,4 (0.7%),14 (2.3%),4 (0.7%),and 0 patients were resistant to NRTIs,NNRTIs,both NRTIs and NNRTIs,and protease inhibitors,respectively.The pretreatment resistance to NNRTIs had much higher frequency than that to NRTIs (2.9% vs.1.3%;χ²=3.929,P=0.047).The prevalence of pretreatment resistance to lamivudine,zidovudine,tenofovir,abacavir,rilpivirine,efavirenz,nevirapine,and lopinavir/ritonavir was 0.8%, 0.3%, 0.7%, 1.0%, 1.3%, 2.8%, 2.9%, and 0, respectively. Conclusions CRF01_AE,CRF07_BC,and CRF08_BC are the three major strains of HIV-infected men≥50 years old newly reported in Guangxi,2020,and the pretreatment drug resistance demonstrates low prevalence.

Objective:To investigate the predictive value of MRI radiologic extranodal extension (rENE) for distant metastasis of prostate cancer (PCa).Methods:The data of 107 patients of initial visit with clinically diagnosed N1 PCa who underwent MRI and 68Ga-prostate specific membrane antigen (PSMA) PET/CT examinations were retrospectively analyzed at Xijing Hospital, Air Force Medical University from January 2017 to April 2022. The rENE was evaluated with MRI. According to the results of 68Ga-PSMA PET/CT, the patients were divided into the distant metastasis group (group M1, 87 cases) and the non-distant metastasis group (group M0, 20 cases). Independent sample t test, Mann-Whitney U test or χ 2 test were used to compare the differences in clinical indicators and rENE between the two groups. The multivariate logistic regression analysis was used to screen the independent risk factors affecting distant metastasis. The receiver operating characteristic (ROC) curve was used to evaluate the predictive efficacy of independent risk factors for PCa distant metastasis. Results:In group M1, 72 cases (82.8%) were rENE positive and 15 cases (17.2%) were rENE negative, and in group M0, 7 cases (35.0%) were rENE positive and 13 cases (65.0%) were rENE negative, and there was a statistically significant difference in rENE between the two groups (χ 2=19.20, P<0.001). There were significant differences in total prostate specific antigen level, International Society of Urological Pathology grade and T stage between the group M1 and the group M0 ( P<0.05). Multivariate logistic regression analysis showed that rENE (OR=6.248, 95%CI 1.807-21.600, P=0.004) was an independent risk factor for distant metastasis of PCa, and the area under the ROC curve of rENE in the diagnosis of distant metastasis of PCa was 0.739 (95%CI 0.607-0.871), the sensitivity was 82.8%, and the specificity was 65.0%. Conclusion:rENE is an independent predictor of distant metastasis of PCa, which has a high efficacy. Compared with patients with rENE negative, PCa patients with rENE positive have a higher degree of invasion and are more likely to have distant metastasis.

Objective: To summarize and analyze the clinical effect of fecal microbiota transplantation (FMT) combined with nutritional support and psychotherapy in patients with "Tetralogy of Tongji" (comprising chronic gastrointestinal dysfunction, mental and psychological disorders, malnutrition, and endocrine disorders). Methods: A longitudinal study was conducted. The inclusion criteria were as follows: (1) patients were under 70 years of age; (2) patients exhibited chronic gastrointestinal dysfunction (in accordance with the Rome IV diagnostic criteria for irritable bowel syndrome ie. chronic functional constipation, diarrhea, abdominal pain and abdominal distention) with onset occurring more than one year previously; (3) patients exhibited malnutrition (body mass index ≤ 18.5 kg/m²); (4) patients exhibited depression, anxiety, or state as diagnosed by a psychologist using the Hamilton anxiety rating scale (HAMA) and the Hamilton depression scale (HAMD); (5) patients were women of childbearing age with amenorrhea or menstrual disorder with a duration ≥6 months. Patients were excluded if they exhibited gastrointestinal bleeding, short bowel syndrome, radiation-induced intestinal injury, intestinal obstruction or inflammatory bowel disease, recurrent/metastatic tumors, systemic infectious diseases, life-threatening systemic comorbidities, intorlerate to nasojejunal, percutaneous gastrostomy / jejunostomy or FMT. The clinical data of 43 patients at Shanghai Tenth People's Hospital exhibiting the "Tetralogy of Tongji" and who received microflora transplantation combined with nutritional support and psychotherapy from June 2017 to June 2021 was prospectively collected. There were 12 males and 31 females with a mean age of 35.2±16.7 years. All 43 patients had chronic gastrointestinal dysfunction. Of these, 24 patients had depression and 19 had anxiety. There were 26 women of reproductive age, including 13 cases of menstrual disorder and 9 cases of amenorrhea. The treatment intervention was a combination of FMT (microflora solution or microflora capsule), nutritional support (enteral nutrition) and psychological intervention. The following were assessed before treatment and 1, 3, 6 months after treatment: (1) gastrointestinal function was assessed using the gastrointestinal symptoms rating scale (GSRS), where a higher score is indicative of more serious gastrointestinal symptoms, and the gastrointestinal quality of life index (GIQLI), where a higher score is indicative of higher quality of life; (2) psychological status was assessed using HAMA and HAMD scores, where a lower score is indicative of reduced severity of anxiety or depression symptoms, respectively; (3) nutritional status was assessed by measurements of total blood protein, albumin, fibrinogen and prealbumin, as well as measurements of body mass and body mass index (BMI); (4) neuroendocrine function was assessed by measurement of blood levels of cortisol, dopamine and noradrenaline, as well as menstruation in women of reproductive age. Results: The follow-up rates at 1, 3 and 6 months after treatment were 90.7% (39/43), 72.1% (31/43) and 55.8% (24/43), respectively. The total effective rate for chronic gastrointestinal dysfunction was 81.4% (35/43), of which the average GSRS score decreased from 29.35±3.56 before treatment to 18.25±2.56 in the sixth month (P<0.001). The average GIQLI score increased from 56.23±10.34 before treatment to 91.04±20.39 in the sixth month (P<0.001). All patients had malnutrition before treatment. After 6 months, their body weight had increased from 40.61±8.88 kg to 50.45±6.23 kg (P<0.001), and BMI had increased from 15.17±1.87 kg/m² to 19.58±1.42 kg/m² (P<0.001). The average total protein level was 60.99± 5.99 g/L before treatment. After 6 months, this had increased to 64.21±4.23 g/L (F=2.715, P=0.022). The average prealbumin level increased from 150.14±56.04 mg/L before treatment to 258.17±86.94 mg/L after 6 months (F=15.124, P<0.001). In this study, 24 patients with depression/depressed state were included. After treatment, the average HAMD score in these patients decreased from 22.79±6.63 before treatment to 9.92±7.24 after 6 months (P<0.001). There were 19 patients with anxiety disorder/anxiety state. After treatment, the average HAMA score in these patients decreased from 17.15±4.34 before treatment to 7.73±4.10 after 6 months (P<0.001). Observing the endocrine efficacy of 26 women of childbearing age, it was found that the effective rate of this treatment on endocrine regulation was 69.2% (18/26). Although there was no significant change in blood cortisol levels after 6 months, average blood dopamine levels decreased from 32.91±10.65 nmol/L before treatment to 13.02±5.58 nmol/L after 6 months (P<0.001). Average blood norepinephrine levels decreased from 49.75±15.23 ng/L before treatment to 19.21±9.58 ng/L after 6 months (P<0.001). Conclusion: The strategy of FMT combined with nutritional support and psychological intervention is effective in improving the symptoms of the "Tetralogy of Tongji".

Aim To study the electrophysiological mechanism of dopamine inhibiting insulin secretion hv voltage-dependent potassium ( Kv) channels.Methods Islets and (3 cells were isolated from male SD rats.D,-like receptor agonist ( SKP38393), D2-like receptor agonist (Quinpirole) and antagonist (Epiclopride) were used according to the experiment.Insulin secretion was detected by insulin radioimmunoassay.Whole-cell j J patch-clamp technique was applied to detect Kv channel currents and action potential duration of p cells.Di- BAC4(3) staining was used to observe membrane potential.Results SKF38393 did not affect insulin secretion and the Kv channel currents.Quinpirole signifi cantly inhibited insulin secretion and increased Kv channel currents.Dopamine significantly inhibited insulin secretion, increased Kv channel currents and shortened action potential duration of p cells, which could be reversed by epiclopride.In addition, dopamine de-creased membrane potential of INS-1 cells.Conclusions Dopamine inhibits insulin secretion by acting on D2-like receptors, resulting in actived Kv channels, shortened action potential duration and decreased cell membrane potential.

Objective:To investigate the effect of hourly ambient temperature exposure on emergency calls in Xuchang city and Zhengzhou city.Methods:The hourly meteorological data, air pollution data and emergency calls of Xuchang city and Zhengzhou city were collected from January 1, 2017 to October 31, 2019. A distributed lag non-linear model was used to calculate the excess relative risk ( ERR). The lag effect and cumulative effect of extreme temperature exposure on emergency calls were evaluated. Results:The relationship between hourly temperature exposure and emergency calls was a U-shaped curve. In Xuchang city and Zhengzhou city, both low and high temperatures would increase the number of hourly emergency calls. The earliest effect of low temperature occurred at a lag of 22 h and 52 h, with ERR values (95% CI) about 0.20% (0.00%, 0.39%) and 0.11% (0.00%, 0.22%), respectively. The earliest effect of high temperature occurred at a lag of 0 h with ERR values about 1.59% (1.09%, 2.09%) and 1.45% (1.22%, 1.69%), respectively. High temperature had the greatest impact on the number of emergency calls of cardiovascular disease at a lag of 4-8 h. The cumulative ERR values (95% CI) of the two cities were 8.70% (4.98%, 12.75%) and 3.89% (2.61%, 5.22%), respectively. Conclusion:High temperature exposure could increase the number of emergency calls within a few hours, while the effect of low temperature would not occur until 22 hours later.

OBJECTIVE: To investigate the incidence rate of infectious diseases during hospitalization in late preterm infants in Beijing, China, as well as the risk factors for infectious diseases and the effect of breastfeeding on the development of infectious diseases. METHODS: Related data were collected from the late preterm infants who were hospitalized in the neonatal wards of 25 hospitals in Beijing, China, from October 23, 2015 to October 30, 2017. According to the feeding pattern, they were divided into a breastfeeding group and a formula feeding group. The two groups were compared in terms of general status and incidence rate of infectious diseases. A multivariate logistic regression analysis was used to investigate the risk factors for infectious diseases. RESULTS: A total of 1 576 late preterm infants were enrolled, with 153 infants in the breastfeeding group and 1 423 in the formula feeding group. Of all infants, 484 (30.71%) experienced infectious diseases. The breastfeeding group had a significantly lower incidence rate of infectious diseases than the formula feeding group (22.88% vs 31.55%, CONCLUSIONS Breastfeeding can significantly reduce the incidence of infectious diseases and is a protective factor against infectious diseases in late preterm infants. Breastfeeding should therefore be actively promoted for late preterm infants during hospitalization.

Objectives: This study aimed to observe the change of arachidonic acid-induced platelet aggregation rate (AA-Ag) and short-term adverse reactions after taking 50 or 100 mg/d aspirin(enteric-coated sustained-release formulation) or 100 mg/d aspirin (enteric-coated aspirin tablet)in the elderly Chinese population (aged 60 years or older). Methods: A total of 1 194 participants aged 60 or older, who should be recommended to take aspirin therapy due to medical reasons, were recruited and randomly assigned into three groups to receive enteric-coated sustained-release aspirin tablet (50 mg, once daily, group A), or 100 mg, once daily (group B) or enteric-coated aspirin tablet 100 mg once daily (group C), respectively. AA-Ag was measured after (14±3)days of aspirin treatment. Adverse events and bleeding events were recorded during the (28±3)days of follow-up. Results: The AA-Ag in group A (n=347), B (n=338) and C (n=332) post 14-day aspirin therapy were 6.65 (4.03,10.84)%, 5.89(3.22,10.03) % and 6.00(3.68,10.09) %, respectively (P>0.05). During the 28 days follow-up, the adverse events rate of group A (n=388), B (n=387) and C (n=385) was 3.87%,3.36%, and 7.95%, and the mild bleeding events rate was 3.09%, 2.33%, and 6.23%, respectively. Adverse events rate and mild bleeding events rate were significantly higher in group C than in group A and B (P<0.05). Conclusions: Compared with 100 mg-dose aspirin, 50 mg-dose aspirin achieves similar anti-platelet aggregation effect in this elderly Chinese population. The short-term adverse events and mild bleeding risk of aspirin with enteric-coated sustained-release formulation were fewer than that of enteric-coated formulation.

Objective To explore the impact of diagnosis related groups (DRGs) payment and drug zero plus on the management of intensive care medicine department. Methods The clinical data of patients in one year from 2016 to 2017 admitted into the Department of ICU in Liuzhou Worker's Hospital concerning their numbers of discharged patients, transferred patients, bed utilization rate, number of bed turnover, average length of stay of discharged patients, cure and improvement rates, admission and discharge diagnostic coincidence rate, 3-day definite diagnosis rate, clinicopathological diagnosis coincidence rate, rescue success rate, total income, drug proportion, consumable proportion, DRGs payment and settlement data, etc were retrospectively analyzed to explore the dual challenges, DRGs payment and drug zero plus, facing the department and how to respond and deal with them. Results In 2016 and 2017, the total incomes of the department of critical care medicine in our hospital were 42.107 0 million yuan and 41.371 3 million yuan respectively, and the medical insurance incomes were 15.03 million yuan and 16.69 million yuan respectively;in 2016 and 2017, 2 693 patients and 2 922 patients were admitted and treated respectively; 595 patients and 577 patients were discharged respectively, with 2 071 patients and 2 334 patients transferred respectively; the balances of the department were 15.48 million yuan and 29.11 million yuan, respectively. From July to December 2017, the medical insurance DRGs payment data suggested that the proportion of loss of the department be 7.02%. Accelerating the Grade 6 electronic medical records and informationization construction, adopting the severe disease information solution program and fine quality control management in the department of critical care medicine can reduce the cost of manpower. Conclusion Our future development direction in the Department of Intensive Care Medicine includes the following aspects: Open source and reduce expenditure, strictly control the proportions of drugs and consumables, improve the balance of the department, and actively respond and deal with the medical insurance DRGs payment.
