OBJECTIVE: The aim of this study is to explore the clinical efficacy and safety of endocrinotherapy combined with Shenqi Pills on hormone-sensitive prostate cancer (HSPC). METHODS: Eighty patients who were diagnosed with HSPC and renal-yang deficiency at the First Affiliated Hospital of Hunan University of Traditional Chinese Medicine and the Hospital of Traditional Chinese Medicine of Mayang Miao Autonomous County from 1st April 2021 to 30th April 2024 were randomly divided into 2 groups. The patients in the control group were treated with androgen deprivation therapy (ADT). And the patients in treatment group were treated with Shenqi Pills orally on the basis of the control group. The baseline data of the two groups were analyzed. After 36 months of treatment, the differences between the two groups were compared in terms of overall survival (OS), prostate-specific antigen (PSA) level, PSA response rate, Functional Assessment Scale for Prostate Cancer Therapy (FACT-P), Chinese medicine evidence scores, testosterone level and safety. RESULTS: A total of 80 study subjects were included in this study, including 42 cases in the treatment group and 38 cases in the control group. There was no statistical difference in the baseline data between the two groups before treatment (P>0.05). At the end of the observation period, a statistically significant difference in OS was found in the treatment group compared to the control group in the subgroup of patients with a disease duration ranged of 0-6 months (P<0.05). There was no statistically significant difference in PSA levels in the treatment group at 3 months (P>0.05). And the differences in the proportion of PSA50 (98.1% vs 91.4%), PSA90 (92.9% vs 84.6%) and the proportion of decrease in PSA (56.7% vs 33.8%) in the treatment group were found compared to those in the control group after 6 months of tre atment. After 12 months of treatment, the scores of FACT-4 and renal-yang deficiency in the treatment group were (95.28±7.93) and (15.73±5.70) respectively, compared to the scores in the control group (［85.46±10.12］ and ［18.20±4.27］ (P<0.05). However, there was no significant difference in serum testosterone (［0.60±0.24］ nmol/L vs ［1.09±2.10］ nmol/L) between the two groups (P>0.05). After 24 months of treatment, there were significant differences in in the FACT-4 total score (［97.95±7.54］ vs ［80.33±8.58］), renal-yang deficiency syndrome score (［14.64±5.15］ vs ［24.94±8.75］) between the treatment group and the control group (P<0.05). However, there was no significant difference in serum testosterone ( ［0.73±1.01］ nmol/L vs ［0.59±0.25］ nmol/L) between the two groups (P> 0.05). Better therapeutic results were showed in the treatment group in terms of total FACT-P score, physical situation score, social and family situation score, emotional state score, functional state score, additional score and renal-yang deficiency symptom score (P<0.05). After treatment, there was no serious adverse reaction in the course of treatment, and no obvious abnormality was found in the liver and kidney function of the patients from two groups. CONCLUSION Endocrinotherapy combined with Shenqi Pills is safe and effective in HSPC and can reduce the risk of death in HSPC patients, and the earlier the intervention, the longer the overall survival of the patients. In addition, this treatment regimen can increase the PSA response rate, improve patients' quality of life, and reduce the renal-yang deficiency syndrome score without the risk of elevating serum testosterone levels.

Objective:To analyze the disease burden in middle-aged and elderly population aged ≥55 in Shenzhen from 2016 to 2030 and provide evidence for the development of healthy aging strategies.Methods:The years of life lost (YLL), years lost due to disability (YLD), and the disability-adjusted life year (DALY) in this population from 2016 to 2022 were calculated. Joinpoint log-linear regression model was used to analyze the time trend. Bayesian age-period-cohort model and grey system model were used to predict YLL, YLD, and DALY in this population in 2030.Results:From 2016 to 2022, the crude DALY rate showed a transient fluctuation in age group 55-74 years, but a pronounced increase in age group ≥85 years. The proportions of YLL and YLD due to non-communicable diseases in all age groups was considerably higher than those due to communicable and nutritional diseases and injuries. In 2022, in all age groups, the YLL due to neoplasms (55-74 years old) and cardiovascular disease (≥75 years old) ranked first, and the YLD due to musculoskeletal disorder ranked first. By 2030, the causes of YLL and YLD ranking first in each age group would be remained, while the ranks of some causes would increase.Conclusions:The age specific characteristics of current and predicted disease burden differed in individuals aged ≥55 years. Therefore, it is necessary to allocate social and medical resources according to the disease burden pattern.

OBJECTIVE To explore the effect of Tuoli Xiaodusan(MDX)on ischemia-reperfusion injury of rat skin flaps and its potential mechanism.METHODS Rats were randomly divided into sham operation group(Sham group),Model group,MDX high-dose group(MDX-H group)and MDX low-dose group(MDX-L group),with 10 rats in each group.After the rat back skin flap model was successfully constructed,the drug was administered by gavage immediately,once a day for 14 consecutive days.The changes of rat skin flaps in each group after surgery were observed,and the survival rate of rat skin flaps in each group was measured on the 14th day after surgery;the histopathological changes of rat skin flaps were observed by HE staining;the protein expression of p-p65 and p-IκBα in the rat skin flap tissue was detected by Western blot;ELISA method was used to detect the expression of TNF-α,IL-1β,and IL-6 cytokines;Ki67 and CD31 immunohistochemical staining were used to observe epidermal basal layer cell prolifera-tion and vascular regeneration.RESULTS Compared with Model group,MDX-H group and MDX-L group had a small amount of e-dema and inflammatory fluid exudation after surgery,and the scab removal time was advanced;the ischemic necrosis of the skin flap was significantly improved,the area of skin flap necrosis was significantly decreased,and the survival rate of rat skin flaps was signifi-cantly increased(P<0.01).In addition,MDX could significantly improve the pathological morphology of ischemia-reperfusion injury in rat back skin flaps,reduce the expression of p-p65 and p-IκBα proteins(P<0.001),and decrease the levels of TNF-α,IL-1β,IL-6 inflammatory factor levels(P<0.05,P<0.01,P<0.001,P<0.000 1).The differences in Ki67 and CD31 also suggested that treatment with MDX accelerate re-epithelialization and blood vessel formation after ischemic flap injury.CONCLUSION MDX plays a role in improving ischemia-reperfusion injury of skin flaps by regulating the NF-κB signaling pathway and accelerating epithelializa-tion and angiogenesis.

Objective To provide references for reasonable equipping of airborne medical equipment oriented to different tasks by constructing a medical equipment requirement model for the helicopter evacuation and rescue team.Methods Relevant basic data were collected and organized on time for routine and emergency medical treatment and elementary medical equipment requirements for types of medical treatment.AnyLogic multi-agent modeling was used to established a medical equipment requirement model for the helicopter evacuation and rescue team,with the casualty,equipment and medical personnel as the agent modules and the logical relationship-based access rules between the agents.An example was taken with a Z-8 helicopter transformed into an ambulance platform to transport the rescue team and casualties,in which a variety of evacuation tasks with multi combinations of light and serious casualties were simulated and the model developed was used to record and analyze the data on waiting time for medical treatment,completion rate,personnel utilization rate and equipment requirement during 100 times of simulation flight.Results The model developed could provide generalized medical equipment allocation programs for the helicopter evacuation and rescue team to complete a variety of evacuation tasks in terms of electronic device,treatment equipment,auxiliary instrument and medical consumables.Conclusion The model developed facilitates rational allocation of medical equipment for the helicopter evacuation and rescue team.[Chinese Medical Equipment Journal,2024,45(5):28-33]

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective To investigate the changing distribution and antibiotic resistance profiles of clinical isolates of Staphylococcus in hospitals across China from 2015 to 2021.Methods Antimicrobial susceptibility testing was conducted for the clinical isolates of Staphylococcus according to the unified protocol of CHINET(China Antimicrobial Surveillance Network)using disk diffusion method and commercial automated systems.The CHINET antimicrobial resistance surveillance data from 2015 to 2021 were interpreted according to the 2021 CLSI breakpoints and analyzed using WHONET 5.6.Results During the period from 2015 to 2021,a total of 204,771 nonduplicate strains of Staphylococcus were isolated,including 136,731(66.8％)strains of Staphylococcus aureus and 68,040(33.2％)strains of coagulase-negative Staphylococcus(CNS).The proportions of S.aureus isolates and CNS isolates did not show significant change.S.aureus strains were mainly isolated from respiratory specimens(38.9±5.1)％,wound,pus and secretions(33.6±4.2)％,and blood(11.9±1.5)％.The CNS strains were predominantly isolated from blood(73.6±4.2)％,cerebrospinal fluid(12.1±2.5)％,and pleural effusion and ascites(8.4±2.1)％.S.aureus strains were mainly isolated from the patients in ICU(17.0±7.3)％,outpatient and emergency(11.6±1.7)％,and department of surgery(11.2±0.9)％,whereas CNS strains were primarily isolated from the patients in ICU(32.2±9.7)％,outpatient and emergency(12.8±4.7)％,and department of internal medicine(11.2±1.9)％.The prevalence of methicillin-resistant strains was 32.9％in S.aureus(MRSA)and 74.1％in CNS(MRCNS).Over the 7-year period,the prevalence of MRSA decreased from 42.1％to 29.2％,and the prevalence of MRCNS decreased from 82.1％to 68.2％.MRSA showed higher resistance rates to all the antimicrobial agents tested except trimethoprim-sulfamethoxazole than methicillin-susceptible S.aureus(MSSA).Over the 7-year period,MRSA strains showed decreasing resistance rates to gentamicin,rifampicin,and levofloxacin,MRCNS showed decreasing resistance rates to gentamicin,erythromycin,rifampicin,and trimethoprim-sulfamethoxazole,but increasing resistance rate to levofloxacin.No vancomycin-resistant strains were detected.The prevalence of linezolid-resistant MRCNS increased from 0.2％to 2.3％over the 7-year period.Conclusions Staphylococcus remains the major pathogen among gram-positive bacteria.MRSA and MRCNS were still the principal antibiotic-resistant gram-positive bacteria.No S.aureus isolates were found resistant to vancomycin or linezolid,but linezolid-resistant strains have been detected in MRCNS isolates,which is an issue of concern.

Objective:To retrospectively analyze and summarize the clinical experience and therapeutic effect of anterograde Needle-perc combined with RIRS, namely N+ R (Needle perc + RIRS) technique in the treatment of complex calyceal diverticular stone.Methods:Retrospective analysis of 23 cases of complex renal caliceal diverticulum stones admitted to our hospital from January 2020 to December 2022. The complex factors mainly include the invisible cervical orifice of diverticulum, large stone volume, and special anatomical location, which makes single RIRS or PCNL treatment difficult or unsuccessful. There were 14 males and 9 females with an average age of (42.3±6.1) years. Three cases were upper calyceal diverticular stone, average size was (0.9±0.2)cm. Nine patients had diverticular stone in the middle posterior calyx, and the average size was (1.2±0.3)cm. The average size of four diverticular stone was (1.8±0.2)cm in the anterior middle calyx. Seven patients had diverticular stone with an average size of (1.3±0.1)cm in lower calyx. Among them, 12 patients underwent RIRS which were difficult or stone undiscovered, and 3 patients underwent PCNL and the operation was terminated due to failure of channel establishment. In our center, oblique supine lithotomy position (male) or prone split-leg position (female) was adopted, and the combined treatment of Needle-perc and RIRS was performed. Needle-perc puncture was completed under the guidance of full ultrasound. During the operation, methylene blue reagent or mutual guidance of two endoscopes was used to find the diverticulum neck and expand the outlet with holmium laser incision. Depending on the size and location of the stones, a single Needle-perc laser lithotripsy combined with stone removal in flexible ureteroscope was used, or dual lasers were be used simultaneously for stone removal under double endoscopes. The first stage stone free rate, operation time, hemoglobin decrease, complications, postoperative hospital stay and other conditions were analyzed.Results:All the 23 operations were completed successfully. The stone free rate within 48 hours and one month after surgery was 78.2% and 100.0% respectively. The average operation time was (61.5±12.2)min. The mean postoperative hospital stay was (2.8±0.6) days. The mean decrease of hemoglobin was (3.6±0.4)g/L. Three patients had fever and one patient had renal subcapsular effusion. After anti-inflammatory and symptomatic treatment, the patient was discharged. There was no incidence of Clavien-Dindo≥Ⅱcomplications such as blood transfusion, abdominal organ injury or urosepsis.Conclusions:Treatment of complex renal caliceal diverticulum stones using N+ R technique of anterograde needle-perc combined with RIRS can effectively improve the success rate of first-stage surgery. Overall, it is safe, efficient and feasible with the advantages of high stone free rate, lower damage, and few postoperative complications.

Knowledge about the neuronal dynamics and the projectome are both essential for understanding how the neuronal network functions in concert. However, it remains challenging to obtain the neural activity and the brain-wide projectome for the same neurons, especially for neurons in subcortical brain regions. Here, by combining in vivo microscopy and high-definition fluorescence micro-optical sectioning tomography, we have developed strategies for mapping the brain-wide projectome of functionally relevant neurons in the somatosensory cortex, the dorsal hippocampus, and the substantia nigra pars compacta. More importantly, we also developed a strategy to achieve acquiring the neural dynamic and brain-wide projectome of the molecularly defined neuronal subtype. The strategies developed in this study solved the essential problem of linking brain-wide projectome to neuronal dynamics for neurons in subcortical structures and provided valuable approaches for understanding how the brain is functionally organized via intricate connectivity patterns.
