Objective:To evaluate the efficacy and safety of traditional Chinese medicine(TCM)in the treatment of male im-mune infertility(MII)by meta-analysis.Methods:We retrieved randomized controlled trial(RCT)on the treatment of male im-mune infertility with traditional Chinese medicine from the databases of WanFang,Chinese Biomedical Literature,Cochrane Library,Weipu,PubMed and CNKI,and performed methodological quality assessment of the RCTs identified and statistical analysis and evalua-tion of the publication bias using the RevMan5.4 software.Results:Totally,25 RCTs(2 563 cases)were included in this study.Compared with Western medicine alone in the treatment of MII,TCM achieved a significantly higher total effectiveness rate(OR=6.35,95% CI:4.96-8.13,P<0.000 01),negative conversion rate of seminal plasma anti-sperm antibodies(OR=4.52,95% CI:2.72-7.51,P<0.000 01),negative rate of serum anti-sperm antibodies(OR=2.98,95% CI:2.23-3.96,P<0.000 01),sperm concentration(MD=15.56,95% CI:11.32-19.79,P<0.000 01),grade a sperm motility(MD=3.85,95% CI:1.91-5.79,P=0.000 01),grade a+b sperm motility(MD=13.77,95% CI:7.06-20.48,P<0.000 1),sperm viability(MD=10.32,95% CI:6.78-13.86,P<0.000 01)and pregnancy rate(OR=3.53,95% CI:2.68-4.63,P<0.000 01),but a lower rate of adverse reactions(OR=0.06,95% CI:0.01-0.23,P<0.000 01).There was no statistically significant difference in the percentage of morphologically abnormal sperm between TCM and Western medicine alone in the treatment of MII(MD=-7.53,95% CI:-15.50-0.44,P=0.06).Conclusion:TCM has a definite effectiveness and high safe in the treatment of male immune infertility.

Male infertility (MI) and male sexual dysfunction (MSD) can often coexist together due to various interplay factors such as psychosexual, sociocultural and relationship dynamics. The presence of each form of MSD can adversely impact male reproduction and treatment strategies will need to be individualized based on patients’ factors, local expertise, and geographical socioeconomic status. The Asia Pacific Society of Sexual Medicine (APSSM) and the Asian Society of Men’s Health and Aging (ASMHA) aim to provide a consensus statement and practical set of clinical recommendations based on current evidence to guide clinicians in the management of MI and MSD within the Asia-Pacific (AP) region. A comprehensive, narrative review of the literature was performed to identify the various forms of MSD and their association with MI. MEDLINE and EMBASE databases were searched for the following English language articles under the following terms: “low libido”, “erectile dysfunction”, “ejaculatory dysfunction”, “premature ejaculation”, “retrograde ejaculation”, “delayed ejaculation”, “anejaculation”, and “orgasmic dysfunction” between January 2001 to June 2022 with emphasis on published guidelines endorsed by various organizations. This APSSM consensus committee panel evaluated and provided evidence-based recommendations on MI and clinically relevant MSD areas using a modified Delphi method by the panel and specific emphasis on locoregional socioeconomic-cultural issues relevant to the AP region. While variations exist in treatment strategies for managing MI and MSD due to geographical expertise, locoregional resources, and sociocultural factors, the panel agreed that comprehensive fertility evaluation with a multidisciplinary management approach to each MSD domain is recommended. It is important to address individual MI issues with an emphasis on improving spermatogenesis and facilitating reproductive avenues while at the same time, managing various MSD conditions with evidence-based treatments. All therapeutic options should be discussed and implemented based on the patient’s individual needs, beliefs and preferences while incorporating locoregional expertise and available resources.

This paper aimed to study the effect of Dalbergia cochinchinensis heartwood on plasma endogenous metabolites in rats with ligation of the left anterior descending coronary artery, and to analyze the mechanism of D. cochinchinensis heartwood in improving acute myocardial ischemic injury. The stability and consistency of the components in the D. cochinchinensis heartwood were verified by the establishment of fingerprint, and 30 male SD rats were randomly divided into a sham group, a model group, and a D. cochinchinensis heartwood(6 g·kg~(-1)) group, with 10 rats in each group. The sham group only opened the chest without ligation, while the other groups established the model of ligation. Ten days after administration, the hearts were taken for hematoxylin-eosin(HE) staining, and the content of heart injury indexes in the plasma creatine kinase isoenzyme(CK-MB) and lactate dehydrogenase(LDH), energy metabolism-related index glucose(Glu) content, and vascular endothelial function index nitric oxide(NO) was determined. The endogenous metabolites were detected by ultra-high-performance liquid chromatography-time-of-flight-mass spectrometry(UPLC-Q-TOF-MS). The results showed that the D. cochinchinensis heartwood reduced the content of CK-MB and LDH in the plasma of rats to relieve myocardial injury, reduced the content of Glu in the plasma, improved myocardial energy metabolism, increased the content of NO, cured the vascular endothelial injury, and promoted vasodilation. D. cochinchinensis heartwood improved the increase of intercellular space, myocardial inflammatory cell infiltration, and myofilament rupture caused by ligation of the left anterior descending coronary artery. The metabolomic study showed that the content of 26 metabolites in the plasma of rats in the model group increased significantly, while the content of 27 metabolites decreased significantly. Twenty metabolites were significantly adjusted after the administration of D. cochinchinensis heartwood. D. cochinchinensis heartwood can significantly adjust the metabolic abnormality in rats with ligation of the left anterior descending coronary artery, and its mechanism may be related to the regulation of cardiac energy metabolism, NO production, and inflammation. The results provide a corresponding basis for further explaining the effect of D. cochinchinensis on the acute myocardial injury.

Objective: To clarify the long-term characteristics of tinnitus following treatment of sudden deafness and its long-term physical and mental effects on patients. Methods: A retrospective analysis was performed on 88 patients (46 males and 42 females; Age from 11 to 89 years) with sudden deafness treated in Department of Otoscope Surgery of Peoples's Libration Army General Hospital in Beijing from April 2020 to January 2021, and the occurrence of tinnitus and treatment effect of all patients were analyzed. Follow-up was conducted for patients with residual tinnitus after treatment for more than 1 year by the investigation and filling in the survey information collection form, Tinnitus Evaluation Questionnaire (TEQ) and Tinnitus Handicap Inventory (THI). Descriptive statistics and SPSS 22.0 software were used for statistical data analysis. Results: In this study, 93.2% (82/88) of patients with sudden deafness were accompanied by tinnitus at the onset, and the proportion of long-term tinnitus after treatment was 90.2% (74/82). After 1 year of treatment for sudden deafness, the improvement of tinnitus was significant in low-frequency sudden deafness compared with those of high-frequency, flat and total deafness sudden deafness (χ2 value was 6.801, 4.568 and 4.038, all P<0.05). In patients with residual tinnitus, 9 (12.2%) patients felt minimal loudness or even no loudness, 34 (46.0%) patients felt slight loudness, 28 (37.8%) patients felt tinnitus was relatively loud, and 3 (4.1%) patients felt tinnitus was loud or noisy. Nine (12.2%) patients's sleep was often affected, 41 (55.4%) patients's sleep was sometimes affected, 9 (12.2%) patients's sleep was rarely affected, 15 (20.3%) patients's sleep was almost not affected. Twenty-eight (37.8%) patients basically completely adapted to tinnitus and 46 (62.2%) patients did not completely adapted to residual tinnitus. Eight (10.8%) patients had no impact on life, 39 (52.7%) patients had slight impact, 22 (29.7%) patients had moderate impact, and the other 5 (6.8%) patients had greater impact. According to tinnitus evaluation questionnaire(TEQ), there were 12 cases (16.2%) of grade Ⅰ, 26 cases (35.1%) of grade Ⅱ, 28 cases (37.8%) of grade Ⅲ, 7 cases (9.5%) of grade Ⅳ and 1 case (1.4%) of grade Ⅴ. According to tinnitus handicap inventory(THI), tinnitus disability was classified into grade Ⅰ, 22 cases (29.7%), grade Ⅱ, 14 cases (18.9%), Grade Ⅲ, 27 cases (36.5%) and grade Ⅳ, 11 cases (14.9%). Conclusion: The rate of residual tinnitus following treatment of sudden deafness is high. Some of the patients can completely adapt residual tinnitus after one year, but some of them will be affected when sleep, work and study. Residual tinnitus can lead to tinnitus disability in different degrees.

OBJECTIVE: To observe the effects of auricular thumbtack needle on breast feeding and lactation function in primiparous women with cesarean section, and to explore its mechanism of action from the perspective of lactation-related gene expression. METHODS: One hundred cases of primiparous women with cesarean section were randomly divided into an observation group (50 cases, 3 cases dropped off) and a control group (50 cases, 2 cases were eliminated). The patients in the control group were treated with routine obstetric care. Based on the treatment of the control group, the patients in the observation group were treated with auricular thumbtack needle at Neifenmi (CO₁₈), Xiong (AH₁₀), Xiongzhui (AH₁₁), Shenmen (TF₄), and Jiaogan (AH_6a), etc., with one side of auricular point selected, only once for a total of 3 d. The lactation initiation time, lactation adequacy rate at postpartum 72 h, exclusive breastfeeding rate at postpartum 42 d, and breastfeeding score after treatment were compared between the two groups. Real-time quantitative PCR and Western blot method were used to detect the mRNA and protein expression levels of TDP-43, Btn1A1 and XDH. RESULTS: After treatment, the lactation initiation time in the observation group was earlier than that in the control group (P<0.01), and breastfeeding score in the observation group was higher than that in the control group (P<0.01). The lactation adequacy rate at postpartum 72 h was 63.8% (30/47) in the observation group, which was higher than 41.7% (20/48) in the control group (P<0.05). The exclusive breastfeeding rate at postpartum 42 d was 72.3% (34/47) in the observation group, which was higher than 47.9% (23/48) in the control group (P<0.05). The mRNA and protein expression levels of TDP-43 and Btn1A1 in breast milk in the observation group were higher than those in the control group (P<0.01), while there was no statistically significant difference in mRNA and protein expression of XDH in breast milk between the two groups (P>0.05). CONCLUSION The auricular thumbtack needle in addition to routine care could promote lactation initiation, improve lactation adequacy rate and exclusive breastfeeding rate in primiparous women with cesarean section, and the action mechanism may be related to up-regulation of TDP-43 and Btn1A1 expression.

Objective: To explore the effect and mechanism of small GTP-binding protein GDP dissociation stimulator (SmgGDS) on the development of obesity. Methods: (1) 8-week-old C57BL/6J mice were randomly assigned to normal diet and high fat diet group, with 6 mice in each group. They were fed regular feed and a high fat diet containing 60% fat for 4 months, respectively. The expression of SmgGDS in epididymal adipose tissue (eWAT), liver, and skeletal muscle were measured using Western-blot. (2) 6-week-old wild-type (WT) and SmgGDS knockdown (KD) mice were divided into four groups, each receiving high fat diet for 4 months (7 in each group) and 7 months (9 in each group). Glucose tolerance test (GTT) and insulin tolerance test (ITT) were conducted; The weight, adipose tissue, and liver weight of mice were recorded; HE staining examined adipose tissue structural changes; Western-blot determined extracellular signal-regulated kinase (ERK) 1/2 phosphorylation levels in eWAT; Real time fluorescence quantitative polymerase chain reaction (RT-qPCR) was used to detect mRNA levels of CCAAT/enhancer binding protein α (C/EBPα), C/EBPβ and peroxisome proliferator activated receptor γ (PPARγ) in eWAT. (3) Mouse embryonic fibroblasts (MEFs) extracted from WT and KD mice were induced for differentiation. Oil red O staining and Western-blot were used to detect lipid droplet and expression of SmgGDS and phospho-ERK; C/EBPα, C/EBPβ and PPARγ mRNA levels were measured using RT-qPCR. (4) 10-week-old C57BL/6J mice were randomly assigned into two groups, with 7 mice in each group. Mice were infected with SmgGDS overexpressing adeno-associated virus (AAV-SmgGDS) or empty vector intraperitoneally, then fed with high fat diet. After 4 weeks, performed GTT and ITT; Recorded the weight and adipose tissue weight of mice; HE staining was used to analyze structural changes of eWAT; Western-blot was used to detect the phosphorylation level of ERK in eWAT. Results: (1) The expression of SmgGDS was significantly upregulated in eWAT of high fat diet fed mice (normal diet group: 0.218±0.037, high fat diet group:0.439±0.072, t=2.74, P=0.034). (2) At 4 months of high fat diet intervention, the glucose tolerance (60 minutes after glucose injection, WT group: 528 mg/dl±21 mg/dl, KD group: 435 mg/dl±17 mg/dl, t=3.47, P=0.030; 90 minutes, WT group: 463 mg/dl±24 mg/dl, KD group: 366 mg/dl±18 mg/dl, t=3.23, P=0.047;120 minutes, WT group: 416 mg/dl±21 mg/dl, KD group: 297 mg/dl±16 mg/dl, t=4.49, P=0.005) and insulin sensitivity (15 minutes after insulin injection, WT group: 77.79%±3.45%, KD group: 54.30%±2.92%, t=3.49, P=0.005; 30 minutes, WT group: 62.27%±5.31%, KD group: 42.25%±1.85%, t=2.978, P=0.024; 90 minutes, WT group: 85.69%±6.63%, KD group: 64.71%±5.41%, t=3.120, P=0.016) of KD mice were significantly improved compared to the WT group, with an increase in eWAT weight ratio (WT: 4.19%±0.18%, KD: 5.12%±0.37%, t=2.28, P=0.042), but a decrease in average adipocyte area (WT group: 5221 μm²±241 μm², KD group: 4410 μm²±196 μm², t=2.61, P=0.026). After 7 months of high fat diet, the eWAT weight ratio of KD mice decreased (WT: 5.02%±0.20%, KD: 3.88%±0.21%, t=3.92, P=0.001) and adipocyte size decreased (WT group: 6 783 μm²±390 μm², KD group: 4785 μm²±303 μm², t=4.05, P=0.002). The phospho-ERK1 in eWAT increased (WT group: 0.174±0.056, KD group: 0.588±0.147, t=2.64, P=0.025), and mRNA level of PPARγ significantly decreased (WT group: 1.018±0.128, KD group: 0.029±0.015, t=7.70, P=0.015). (3) The expression of SmgGDS was significantly increased in differentiated MEF (undifferentiated: 6.789±0.511, differentiated: 10.170±0.523, t=4.63, P=0.010); SmgGDS knock-down inhibited lipid droplet formation in MEF (WT group: 1.00±0.02, KD group: 0.88±0.02, t=5.05, P=0.007) and increased ERK1 (WT group: 0.600±0.179, KD group: 1.325±0.102, t=3.52, P=0.025) and ERK2 (WT group: 2.179±0.687, KD group: 5.200±0.814, t=2.84, P=0.047) activity, which can be reversed by ERK1/2 inhibitor. (4) SmgGDS over expression resulted in weight gain, increased eWAT weight (control group: 3.29%±0.36%, AAV-SmgGDS group: 4.27%±0.26%, t=2.20, P=0.048) and adipocyte size (control group: 3525 μm²±454 μm², AAV-SmgGDS group: 5326 μm²±655 μm², t=2.26, P=0.047), impaired insulin sensitivity(30 minutes after insulin injection, control group: 44.03%±4.29%, AAV-SmgGDS group: 62.70%±2.81%, t=3.06, P=0.019), and decreased ERK1 (control group: 0.829±0.077, AAV-SmgGDS group: 0.326±0.036, t=5.96, P=0.001)and ERK2 (control group: 5.748±0.287, AAV-SmgGDS group: 2.999±0.845, t=3.08, P=0.022) activity in eWAT. Conclusion: SmgGDS knockdown improves obesity related glucose metabolism disorder by inhibiting adipogenesis and adipose tissue hypertrophy, which is associated with ERK activation.

OBJECTIVE: To observe the efficacy and safety of CLAE intensive chemotherapy followed by allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with relapsed/refractory acute leukemia (R/R AL). METHODS: CLAE regimen [cladribine 5 mg/(m²·d), d 1-5; cytarabine 1.5 g/(m²·d), d 1-5; etoposide 100 mg/(m²·d), d 3-5] followed by allo-HSCT was used to treat 3 R/R AL patients. The patients received CLAE chemotherapy in relapsed or refractory status and underwent bone marrow puncture to judge myelodysplastic state. After an interval of 3 to 5 days, followed by preconditioning regimen for allo-HSCT [fludarabine 30 mg/(m²·d), d -7 to d -3; busulfan 0.8 mg/kg q6h, d -6 to d -3 or d -5 to d -2. If the bone marrow hyperplasia was not active and the blasts were less than 10%, busulfan should be used for 3 days. If the bone marrow hyperplasia was active and the blasts were more than 10%, busulfan should be used for 4 days]. Cyclosporin A, mycophenolate mofetil and short-term methotrexate were used for graft-versus-host disease (GVHD) prevention. After transplantation, the status of minimal residual disease (MRD) and bone marrow chimerism were regularly monitored in all 3 patients, and demethylation drugs or dasatinib were used to prevent recurrence 3 months after transplantation. RESULTS: 2 patients with t(11;19) translocation and relapse/refractory acute myeloid leukemia recurred within 6 months after induction of remission, and received intensive chemotherapy with CLAE regimen followed by haploidentical allo-HSCT and unrelated donor allo-HSCT, respectively. The two patients both relapsed 6 months after transplantation, then achieved complete remission by donor lymphocyte infusion, interferon, interleukin-2 and other methods, and disease-free survival was 2 years after transplantation. The other patient was chronic myelogenous leukemia who developed acute lymphoblastic leukemia during oral administration of tyrosine kinase inhibitor, accompanied by T315I and E255K mutations in ABL1 kinase region and additional chromosomal abnormalities. After morphological remission by induction chemotherapy, central nervous system leukemia was complicated. Intensive chemotherapy with CLAE regimen followed by sibling allo-HSCT was performed in the positive state of MRD. The patient relapsed 3 months after transplantation, and achieved remission after chimeric antigen receptor T-cell (CAR-T) therapy, however, he died 5 months after transplantation because of severe cytokine release syndrome (CRS) and GVHD. CONCLUSION CLAE regimen followed by allo-HSCT may be an effective salvage treatment option for R/R AL patients to prolong the overall survival.
