ObjectiveTo investigate the therapeutic effects of direct-acting antiviral agents (DAAs) combined regimens for hepatitis C virus (HCV) patients in Dehong Prefecture, Yunnan Province from 2022 to 2024, to analyze the characteristics of treatment failure patients, so as to provide a basis for discovering more effective treatment regimens in the future. MethodsData on HCV prevention and treatment in Dehong Prefecture was extracted from the China Disease Control and Prevention Information System. A total of 617 patients with HCV antiviral therapy were included, and the differences in variable characteristics among patients with different genotypes were analyzed using comparative statistical tests, including basic socio-demographic characteristics, biochemical testing indicators, and information on previous treatment and current treatment. In addition, the cure rate of HCV patients with diverse characteristics was compared, and the potential causes of treatment failure were explored simultaneously. ResultsThe cure rate of HCV was 96.8%, and statistically significant differences were observed in aspartate transaminase (AST) and alanine transaminase (ALT) levels, previous antiviral therapy history and initial treatment regimens among patients with different HCV genotypes (all P<0.05). Among the multi-type combination regimens, the cure rate of sofosbuvir (SOF)-containing regimens was 97.00%, that of velpatasvir (VEL)-containing regimens was 95.45%, and the cure rate of other treatment regimens, including the regimens with ribavirin (RIB) intervention, was 93.10%. Among the patients with treatment failure, 45.00% had genotype 3, 40.00% had abnormal abdominal ultrasound results, and all presented with elevated baseline AST test levels. ConclusionThe clinical treatment of HCV patients should consider the differences in genotype and biochemical test results. DAAs combined regimens for HCV have achieved a high cure rate in Dehong Prefecture and are applicable to HCV patients with diverse clinical characteristics, providing research evidence for wider application.

Objective To investigate the clinical value of Yishen Gujing Kangyan Prescription(with the actions of benefiting the kidneys,consolidating essence and anti-inflammatory,mainly composed of Imperatae Rhizoma,Codonopsis Radix,Corni Fructus,Moutan Cortex,Lycii Fructus,Cuscutae Semen,Dioscoreae Rhizoma,honey-roasted Astragali Radix,Poria,Rehmanniae Radix Praeparata,etc.)in the treatment of lupus nephritis(LN)of qi and yin deficiency type.Methods A total of 116 patients with LN of qi and yin deficiency type were randomly divided into observation group and control group,58 cases in each group.The control group was given conventional western medicine treatment,and the observation group was treated with the combination of Yishen Gujing Kangyan Prescription on the basis of treatment for the control group.Both groups were treated for a period of 6 months.The changes of traditional Chinese medicine(TCM)syndrome scores,renal function parameters,immune function indicators,serum interleukin 18(IL-18),homocysteine(Hcy),transforming growth factor β1(TGF-β1),cystatin C(Cys C)levels in the two groups were observed before and after the treatment.After treatment,the clinical efficacy and the negative-conversion of anti-double-stranded DNA(ds-DNA)antibody were compared between the two groups.Results(1)After 6 months of treatment,the total effective rate of the observation group was 94.83%(55/58),and that of the control group was 75.86%(44/58).The intergroup comparison showed that the therapeutic effect of the observation group was significantly superior to that of the control group(χ2 = 5.453,P＜0.05).(2)After treatment,the scores of primary symptoms(edema,fatigue)and secondary symptoms(lumbar and knee soreness,loose stools)in the two groups were lower than those before treatment(P＜0.05),and the effect on lowering the scores in the observation group was significantly superior to that in the control group(P＜0.01).(3)After treatment,the levels of renal function parameters of blood urea nitrogen(BUN),serum creatinine(Scr),and 24-hour urine protein quantification of the two groups were all lower than those before treatment(P＜0.05),and the effect on lowering renal function parameters in the observation group was significantly superior to that in the control group(P＜0.01).(4)After treatment,serum IL-18,TGF-β1,Hcy and Cys C levels of the two groups of patients were all reduced compared with those before treatment(P＜0.05),and the effect on lowering the levels of inflammatory factors and fibrosis parameters in the observation group was significantly superior to that in the control group(P＜0.01).(5)After treatment,the levels of immune function indicators of T cell subsets CD4+,CD4+/CD8+ and complement C3 in the two groups were increased compared with those before treatment(P＜0.05),and the increase in the observation group was significantly superior to that in the control group,and the differences were all statistically significant(P＜0.05 or P＜0.01).(6)The negative-conversion rate of anti-ds-DNA antibody in the observation group was 77.59%(45/58),which was significantly higher than that in the control group(55.17%,32/58),and the difference was statistically significant between the two groups(P＜0.05).Conclusion For the treatment of patients with LN of qi and yin deficiency type,Yishen Gujing Kangyan Prescription exerts synergistic effect on reducing inflammatory response,regulating immune function,promoting the recovery of renal function,and enhancing clinical efficacy.

Objective:To investigate the protective mechanism of TRPV4 channel inhibitor on blood-brain barrier(BBB)damage after traumatic brain injury(TBI).Methods:The TBI rat model was established.TRPV4 channel inhibitor HC067047 or PKC-δ inhibitor Rottlerin was used to detect changes in BBB permeability,neurological function score,and the expression of microvascular endothelial tight junction proteins ZO-1 and ZO-2 in brain injury areas after TBI.Results:Compared with the Sham group,BBB permeability significantly increased,brain neurological function score significantly decreased,and the expression of ZO-1 and ZO-2 significantly decreased in TBI group(P＜0.05).Compared with the TBI group,after administration of HC067047 or Rottlerin,changes in BBB permeability,brain neurological function score,the expression of ZO-1 and ZO-2 were partially reversed(P＜0.05).Conclusions:TBI-induced BBB injury may be mediated by TRPV4 channel regulating PKC-δ signaling pathway to affect the expression of tight junction proteins ZO-1 and ZO-2.Inhibition of TRPV4 channel function or PKC-δ signal molecule can partially alleviate BBB damage induced by TBI.This study may provide new ideas for the treatment of clinical TBI.

BACKGROUND:Intervertebral disc degeneration is an important cause of low back pain.At present,there are many modeling methods for disc degeneration in China and abroad,but there is not a model for low back pain due to disc degeneration. OBJECTIVE:To compare the effect of mechanical puncture combined with tumor necrosis factor α and complete Freund's adjuvant with a conventional disc mechanical puncture alone. METHODS:A total of 18 male adult Sprague-Dawley rats were randomly divided into 3 groups,with 6 animals in each group.No treatment was given in the blank group.Animal models of intervertebral disc degeneration were made in the L4-5 segments of rats in the control using conventional mechanical puncture.In the experimental group,on the basis of mechanical puncture,tumor necrosis factor α+complete Freund's adjuvant was injected into the L4-5 intervertebral discs using a microinjector to establish a model of disc degeneration induced by mechanical puncture combined with inflammatory factors.Four weeks after surgery,the pain threshold of rats was measured by the hot plate method for assessing the perception of heat injury in rats with intervertebral disc degeneration.MRI examination was performed to observe the disc degeneration in each group.ELISA was used to detect the levels of serum tumor necrosis factor α,interleukin 1β,interleukin 6 and prostaglandin E2.Hematoxylin-eosin and Safranin O-fast green staining were used to observe the morphological changes of the disc. RESULTS AND CONCLUSION:In terms of pain,the behavioral pain threshold of the experimental group was continuously decreased,and the levels of serum inflammatory factors were significantly higher compared with the control group.In terms of morphology,the MRI results showed that the L4-5 nucleus pulposus signal completely disappeared in the experimental group.Histopathological results showed that in the control group,the nucleus pulposus was intact,more notochord cells were visible,and some fiber rings were ruptured,while in the experimental group,there are fewer notochord cells and the structure of the nucleus pulposus and fibrous ring is disturbed,with the boundary disappearing.To conclude,mechanical puncture combined with tumor necrosis factor alpha and complete Freund's adjuvant can successfully establish a discogenic low back pain model in rats.This operation is simple and economical to achieve obvious disc degeneration and low back pain,with greatly shortened molding cycle.This model can be used as a reference for studying discogenic low back pain models.

Objective To summarize the epidemiological and clinical features of infectious diseases of the central nervous system(CNS)by a single-center analysis.Methods A retrospective analysis was conducted on the data of 1247 cases of CNS infectious diseases diagnosed and treated in the First Medical Center of PLA General Hospital from 2001 to 2020.Results The data for this group of CNS infectious diseases by disease type in descending order of number of cases were viruses 743(59.6％),Mycobacterium tuberculosis 249(20.0％),other bacteria 150(12.0％),fungi 68(5.5％),parasites 18(1.4％),Treponema pallidum 18(1.4％)and rickettsia 1(0.1％).The number of cases increased by 177 cases(33.1％)in the latter 10 years compared to the previous 10 years(P<0.05).No significant difference in seasonal distribution pattern of data between disease types(P>0.05).Male to female ratio is 1.87︰1,mostly under 60 years of age.Viruses are more likely to infect students,most often at university/college level and above,farmers are overrepresented among bacteria and Mycobacterium tuberculosis,and more infections of Treponema pallidum in workers.CNS infectious diseases are characterized by fever,headache and signs of meningeal irritation,with the adductor nerve being the more commonly involved cranial nerve.Matagenomic next-generation sequencing improves clinical diagnostic capabilities.The median hospital days for CNS infectious diseases are 18.00(11.00,27.00)and median hospital costs are ￥29,500(￥16,000,￥59,200).The mortality rate from CNS infectious diseases is 1.6％.Conclusions The incidence of CNS infectious diseases is increasing last ten years,with complex clinical presentation,severe symptoms and poor prognosis.Early and accurate diagnosis and standardized clinical treatment can significantly reduce the morbidity and mortality rate and ease the burden of disease.

Objective To evaluate the efficacy and safety of brexpiprazole in treating acute schizophrenia.Methods Patients with schizophrenia were randomly divided into treatment group and control group.The treatment group was given brexpiprozole 2-4 mg·d-1 orally and the control group was given aripiprazole 10-20 mg·d-1orally,both were treated for 6 weeks.Clinical efficacy of the two groups,the response rate at endpoint,the changes from baseline to endpoint of Positive and Negative Syndrome Scale(PANSS),Clinical Global Impression-Improvement(CGI-S),Personal and Social Performance scale(PSP),PANSS Positive syndrome subscale,PANSS negative syndrome subscale were compared.The incidence of treatment-related adverse events in two groups were compared.Results There were 184 patients in treatment group and 186 patients in control group.After treatment,the response rates of treatment group and control group were 79.50％(140 cases/184 cases)and 82.40％(150 cases/186 cases),the scores of CGI-I of treatment group and control group were(2.00±1.20)and(1.90±1.01),with no significant difference(all P＞0.05).From baseline to Week 6,the mean change of PANSS total score wese(-30.70±16.96)points in treatment group and(-32.20±17.00)points in control group,with no significant difference(P＞0.05).The changes of CGI-S scores in treatment group and control group were(-2.00±1.27)and(-1.90±1.22)points,PSP scores were(18.80±14.77)and(19.20±14.55)points,PANSS positive syndrome scores were(-10.30±5.93)and(-10.80±5.81)points,PANSS negative syndrome scores were(-6.80±5.98)and(-7.30±5.15)points,with no significant difference(P＞0.05).There was no significant difference in the incidence of treatment-related adverse events between the two group(69.00％vs.64.50％,P＞0.05).Conclusion The non-inferiority of Brexpiprazole to aripiprazole was established,with comparable efficacy and acceptability.

Gynecological cancer significantly affect the health of women.This review aimed to describe the global patterns and trends in the survival of patients with gynecological cancers.We searched PubMed,Embase,Web of Science,SinoMed,and SEER for survival analyses of cancer registration data of cervical,endometrial,and ovarian cancers published between 1980 and 2022.Globally,the highest 5-year observed survival rate for cervical cancer was 76.5%in Anshan,Liaoning,China(2008-2017).The 5-year observed survival rates of endometrial and ovarian cancers were higher in Finland(1995-1999,82.5%)and Singapore(1988-1992,62.0%).The 5-year relative survival rate of cervical cancer patients was higher in Haining,Zhejiang,China(2011-2014,85.8%).Korea ranked first at 89.0%and 64.5%for endometrial and ovarian cancers,respectively.Survival rates have improved for cervical,endometrial,and ovarian cancers.Patients aged≥75 years and those with advanced-stage disease had the worst 5-year survival rates.Survival rates were better for squamous cell carcinoma in cervical cancer,for endometrial carcinoma and mucinous adenocarcinoma in endometrial cancer,and for germ cell and sex-cord stromal tumors in ovarian cancer.Over the past four decades,the survival rates of gynecological cancers have increased globally,with notable increases in cervical and endometrial cancers.Survival rates are higher in developed countries,with a slow-growing trend.Future studies should focus on improving survival,especially in ovarian cancer patients.

Objective:To analyze the epidemic characteristics and trends of newly reported HIV-infected people among Chinese and Burmese in Dehong Dai and Jingpo Autonomous Prefecture (Dehong Prefecture) of Yunnan Province, China, from 2000 to 2023, and provide evidence for formμlating AIDS prevention and control measures for the Burmese living in Dehong.Methods:The data were obtained from the Chinese Disease Control and Prevention Information System. The distribution of HIV-infected people with different population characteristics was analyzed, and the Joinpoint regression model was used to analyze the temporal trend of crude detection rate in different genders, ethnicities, and ages.Results:From 2000 to 2023, 24 989 newly HIV infections were reported in Dehong Prefecture, of which 14 594 (58.4%) were Chinese and 10 395 (41.6%) were Burmese. Compared with Chinese, Burmese women (32.9%, 3 416/10 395), those aged 20-29 (40.9%, 4 248/10 395), and Jingpo people (26.7%, 2 773/10 395) accounted for a higher proportion. The new diagnosis rate of Chinese nationals increased from 1.0/10 000 in 2000 to 15.4/10 000 in 2004, and then showed a downward trend, falling to 1.2/10 000 in 2023. Among them, compared with other age groups, Dai and other ethnic groups and women, the new diagnosis rate among 20-49 age group, Jingpo and men were relatively higher, at 1.7/10 000, 2.3/10 000 and 1.3/10 000 respectively. Regarding the method of detection, the Chinese HIV-infected people were mainly detected by key population testing (35.7%), while the Burmese HIV-infected people by key population testing (28.9%) and physical examination for entry-exit personnel (25.3%). The transmission routes of both nationalities were mainly heterosexual transmission, but compared with Chinese HIV-infected persons, the proportion of Burmese infected persons through non-marital non-commercial transmission was relatively higher (66.4% vs. 60.6%). The proportion of Chinese nationals with a first CD4 +T lymphocyte (CD4) counts of <200 cells/μl (28.9%) was higher than that of Burmese nationals (19.8%). Conclusions:The rising trend of HIV infection among Chinese and Burmese people in Dehong Prefecture from 2000 to 2023 slowed down. The new diagnosis rate was higher in the 20-49 age group, Jingpo and men. Compared with Burmese HIV-infected people, the proportion of Chinese HIV-infected people with first CD4 counts <200 cells/μl was relatively higher. Comprehensive interventions should be further carried out for Myanmar nationals, and efforts should be made to expand testing for Chinese nationals.

The close relationship between gastric cancer (GC) and type 2 diabetes mellitus (T2DM) has garnered significant attention. On one hand, T2DM may play a role in the development and progression of GC, correlating with poor patient outcomes. On the other hand, after radical surgery for GC, T2DM can be effectively managed, potentially improving tumor prognosis. In recent years, bariatric and metabolic surgery (BMS) has revolutionized T2DM treatment for obese and overweight patients. Comparative analyses reveal similarities between surgical approaches for gastric cancer and BMS, leading to the emergence of the onco-metabolic surgery (OMS) concept, which suggests that radical tumor resection and T2DM remission in GC patients can be potentially achieved through a single procedure. However, there are notable differences between OMS and BMS, including target populations, surgical details, and perioperative management. Therefore, optimizing the application of the OMS concept in GC patients holds significant clinical importance. This article provides a review to facilitate the better implementation of this concept in practice.
