Objective:To analyze the factors for low libido in male patients with sexual dysfunction and provide some evidence for the clinical diagnosis and treatment of the condition.Methods:We retrospectively analyzed the clinical data on 111 cases of sex-ual dysfunction(including disorders in erection,ejaculation or libido)treated in the Zhengzhou University First Hospital from June to September 2023.According to the patients'complaints of low libido or accompanied symptoms,we divided them into a normal libido group(n=68)and a low libido(n=43),obtained their scores on IIEF-5,Premature Ejaculation Diagnostic Tool(PEDT),13-1-tem Self-Rating Libido Scale for Males(SRLS-M),Patients'Health Questionnaire-9(PHQ-9)and General Anxiety Disorder-7(GAD-7),examined the levels of the sexual hormones FSH,LH,PRL,T,free testosterone(fT),E2,?insulin-like growth factor 1(IGF-1)and growth hormone(GH),compared the basic parameters between the two groups,and analyzed their correlation with the libido values.Results:The IIEF-5,PEDT and libido scores and IGF-1 level were significantly higher and the GAD-7 score remark-ably lower in the normal than in the low libido group(P＜0.05),but no statistically significant differences were observed between the two groups in the PHQ-9 score and the levels FSH,LH,PRL,T,fT,E2,T/E2 and GH(P＞0.05).The libido value was correla-ted positively with the I1EF-5(r=0.28,P＜0.01)and PEDT scores(r=0.29,P＜0.01)and IGF-1 level(r=0.23,P＜0.05),but negatively with the GAD-7 score(r=-0.21,P＜0.05).Conclusion:Low libido results from multiple factors,which cannot be fully explained by sexual hormone levels but is closely related to the decreased level of IGF-1 and severity of ED and anxiety.

Since 2015 when the transmission of schistosomiasis was controlled in China, the country has been moving towards elimination of schistosomiasis, with the surveillance-response as the main interventions for schistosomiasis control. During the period of the 13th Five-Year Plan, the transmission of schistosomiasis had been interrupted in four provinces of Sichuan, Jiangsu, Yunnan and Hubei and the prevalence of schistosomiasis has been at the historically lowest level in China. As a consequence, the goal set in The 13th Five-Year National Schistosomiasis Control Program in China is almost achieved. However, there are multiple challenges during the stage moving towards elimination of schistosomiasis in China, including the widespread distribution of intermediate host snails and complicated snail habitats, many types of sources of Schistosoma japonicum infections and difficulty in management of bovines and sheep, unmet requirements for the current schistosomiasis control program with the currently available tools, and vulnerable control achievements. During the 14th Five-Year period, it is crucial to consolidate the schistosomiasis control achievements and gradually solve the above difficulties, and critical to provide the basis for achieving the ultimate goal of elimination of schistosomiasis in China. Based on the past experiences from the national schistosomiasis control program and the challenges for schistosomiasis elimination in China, an expert consensus has been reached pertaining to the objectives, control strategy and measures for The 14th Five-Year National Schistosomiasis Control Program in China, so as to provide insights in to the development of The 14th Five-Year National Schistosomiasis Control Program in China.

Objective To investigate the application and advantages of alternative vascular hemihepatic occlusion in anatomic mesohepatectomy.MethodsThe clinical data of 57 patients with liver cancer who underwent operation in hepatobiliary surgery of Fuzhou general hospital from January 2014 to December 2017 were retrospectively analyzed.According to the surgery method, the patients were divided into observation group and control group, 34 cases in observation group were performed anatomic mesohepatectomy with alternative hemihepatic occlusion, 23 cases in control group were treated with non-anatomical liver lobectomy.The clinical effect of two groups were compared.Results The observation group was significantly better than the control group in terms of operation time, intraoperative blood loss, length of hospital stay, hospitalization costs, ALB at 1, 3, 5 days after surgery, ALT and AST at 1, 3, 5, 7 days after surgery, the differences were significant (P＜0.05).There was no perioperative deaths in the two groups.ConclusionApplied alternative hemihepatic vascular occlusion in anatomic mesohepatectomy can achieve good short-term curative effect and high safety.

AIM:To analyze the imageological changes of acute and chronic central serous chorioretinopathy (CSC) by 2 types of optical coherence tomography (OCT). METHODS:A retrospective analysis was performed, inclu-ding data of 60 eyes from 56 patients with CSC diagnosed by conventional eye examination, fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA), which were divided into acute group (28 eyes of 28 patients) and chronic group (32 eyes of 28 patients) according to imageological examinations and duration (6 months). Optical coher-ence tomography angiography (OCTA) and spectral domain optical coherence tomography ( SD-OCT) were performed to study the vessel density of the chorioretinal leyers and the integrity of the outer retinal structure. RESULTS:In the pa-tients with chronic CSC, OCTA in 4 eyes ( 12.50% ) revealed the presence of a distinct choroidal neovascularization (CNV), while no evidence of CNV in ICGA was observed. However, no sign of CNV in acute CSC group both on OCTA and ICGA was found. The occurrence of 'dark areas' in chronic CSC was much higher than that in acute CSC ( P <0.01). In addition, the integrity of the outer retinal structure (defined as tissue between external limiting membrane and retinal pigment epithelium) in acute group was significantly better than that in chronic group ( P <0.01). CONCLU-SION:Our study demonstrates the existing secondary CNV that is not demonstrated by ICGA in the chronic CSC patients, and the different characteristics of retinochoroid structures between acute and chronic CSC in OCTA and SD-OCT are ob- served. Chronic CSC has more severe structural changes.

Chlamydia trachomatis infection is one of the most prevalent sexually transmitted diseases in males and studies on its pathogenic and immunologic mechanisms are rather limited. Animal models play an important role in studying the pathogenesis, course and treatment of human diseases, and those of male genital tract chlamydial infection are relatively few and not well developed. This article focuses on the chlamydia species, animal species, infection route, infected organ, and infection process of chlamydia, as well as its impact on reproduction, aiming to provide some help for further studies of male genital tract chlamydial infection.

Objective: To explore the expressions of transient receptor potential vanilloid 1 (TRPV1) and TRP ankyrin 1 (TRPA1) in the dorsal root ganglion (DRG) and their action mechanisms in the rat model of orchialgia. METHODS: The models of orchialgia were established in male SD rats by injection of 2% acetic acid into the testis. Then the number of spontaneous pain responses and withdrawal latency in the model rats were recorded by behavioral tests and the expressions of TRPV1 and TRPA1 in T13－L1 DRGs determined by RT-qPCR, Western blot and immunofluorescence staining. RESULTS: Compared with the normal control rats, the orchialgia models showed a significant increase in the number of spontaneous pain responses (0.13 ± 0.35 vs 22.63 ± 3.42, P<0.01) and a decrease in the withdrawal latency at 4 hours after injection (［12.75 ± 1.50］ vs ［4.85 ± 1.00］ s, P<0.05). The mRNA expressions of both TRPV1 and TRPA1 were observed in the membrane of the neurons in the DRG, the former increased by 1.77 times and the latter by 1.75 times that of the control (P<0.05). CONCLUSIONS The expressions of TRPV1 and TRPA1 were up-regulated in the DRG of the rat models of orchialgia, which may be involved in the allodynia and hyperalgesia of the rats.

OBJECTIVES: To explore the correlation between early postmortem interval （PMI） and eight RNA markers of rat's brain at different temperatures. METHODS: Total 222 SD rats were randomly divided into control group （PMI=0 h） and four experimental groups. And the rats in the experimental groups were sacrificed by cervical dislocation and respectively kept at 5 ℃, 15 ℃, 25 ℃ and 35 ℃ in a controlled environment chamber. The RNA was extracted from brain tissues, which was taken at 9 time points from 1 h to 24 h postmortem. The expression levels of eight markers, β-actin, GAPDH, RPS29, 18S rRNA, 5S rRNA, U6 snRNA, miRNA-9 and miRNA-125b, were detected using real-time fluorescent quantitative PCR, respectively. Proper internal reference was selected by geNorm software. Regression analysis of normalized RNA markers was performed by SPSS software. Mathematical model for PMI estimation was established using R software. Another 6 SD rats with known PMI were used to verify the mathematical model. RESULTS: 5S rRNA, miR-9 and miR-125b were suitable as internal reference markers for their stable expression. Both β-actin and GAPDH had well time-dependent degradation patterns and degraded continually with prolongation of PMI in 24 h postmortem. The mathematical model of the variation of ΔCt values with PMI and temperature was set up by R software and the model could be used for PMI estimation. The average error rates of model validation using β-actin and GAPDH were 14.1% and 22.2%, respectively. CONCLUSIONS The expression levels of β-actin and GAPDH are well correlated with PMI and environmental temperature. The mathematical model established in present study can provide references for estimating early PMI under various temperature conditions.

OBJECTIVETo investigate the indications, safety and efficacy of catheter directed thrombolysis for early left lower extremity deep venous thrombosis (DVT) without vena cava filters protection.

METHODSClinical data of 54 cases of early left lower extremity DVT received catheter directed thrombolysis without vena cava filters from July 2008 to June 2010 were retrospectively analyzed. The thrombosis was entire without free floating clots and no thrombosis in vena cava detected with ultrasound scan. Twenty-five patients were male and 29 were female with the average age of 52.8 years. Fifty-one of which were iliofemoral and popliteal, the other 3 were iliofemoral. The course were ≤ 7 d in 45 cases and these were 8 to 30 d in 9 cases. Urokinase of 300 000 U was infused through catheters per 2 h twice a day. Meanwhile 4000 U of low weight heparin was administered subcutaneously per 12 h, or heparin infusion at dosage of 18 U×kg(-1)×h(-1).

RESULTSThe procedure technically succeeded in all patients. In total cases venous score decreased to 4.6 ± 2.1 post 6 to 10 d of thrombolysis from 10.8 ± 1.0 with thrombolysis rate of 58% ± 18% which was not significantly different between groups of ≤ 7 d and 8 to 30 d (t = 1.02, P = 0.34). On 14(th) day, 11 patients (20.4%) completely recovered, 35 cases (64.8%) experienced large improvement, 8 patients (14.8%) had mild improvement and nobody was failed, resulting in total efficacy of 100%. No patient developed clinical symptomatic pulmonary embolism. SpO2 did not alter markedly post thrombolysis [(91.0 ± 2.6)% vs. (90.8 ± 2.4)%, t = 2.03, P = 0.05]. No patients suffered from cerebral hemorrhage and haemoturia, and catheter induced inflammation occurred in 4 cases (7.41%). There was mild bleeding in puncture sites in 11 patients (20.4%) during the course. There were 36 patients (66.7%) had been followed up with the time of 6 to 21 months. In which 31 cases had no lower extremity edema or had mild edema after activities. Two patients developed serious edema after activities for deep venous insufficiency. Three cases combined with malignant tumor or renal failure recurred.

CONCLUSIONSFor early left extremity DVT which is entire without free floating clots and no thrombosis in vena cava, catheter directed thrombolysis without filter protection maybe administered with safety, efficiency and lower expense.

Recent randomized controlled clinical trials in Africa have demonstrated that adult male circumcision (MC) efficiently decreases the rate of HIV, HPV and HSV-2 infections. Many studies have clearly shown that MC is a simple, safe, and cost-effective method for the prevention of sexually transmitted diseases and urinary tract infection, and for improving genital hygiene. While a 30% MC prevalence exists worldwide, only 5% or less of the Chinese males have undergone circumcision. In this review, we report recent trends in international MC and HIV prevention efforts, as well as the potential benefits and importance of promoting MC in China. We appeal to medical and public health authorities to pay close attention to the international experience in MC and HIV prevention.
