The current situation of childrearing in the elderly and low birth rate showed that the prevention and treatment of infertility risk caused by the decline of male reproductive function are increasingly becoming prominent.The decline of male reproductive function is closely related to the hypothalamic-pituitary-gonadal axis,oxygen free radicals,blood-testis barrier,and the apoptosis of spermatogenic cells.Traditional Chinese medicine believes that the kidney stores essence and is in charge of reproduction,and the decline of reproductive function is closely related to the imbalance of yin and yang of the kidney.Therefore,kidney-supplementing method is helpful for treating the decline of reproductive function caused by kidney deficiency.Kidney-supplementing prescriptions were effective on systematically regulating the function of the hypothalamic-pituitary-gonadal axis,thus to significantly delay the decline of reproductive function,were effective on removing excessive oxygen free radicals in the body and protecting cells from oxidative damage,and were effective on improving spermatogenesis by restoring the blood-testis barrier and regulating the apoptosis of spermatogenic cells.The representative kidney-supplementing prescriptions for improving the decline of reproductive function caused by kidney deficiency include Wuzi Yanzong Pills,Shenqi Pills,Yougui Pills,Liuwei Dihuang Pills,Zuogui Pills and Guilu Erxian Soft Extract.The above formulas presented no single therapeutic mechanism but multiple-way,multiple-level and multiple-target mechanism,and the formulas can comprehensively regulate the internal environment of the body,so as to achieve the purpose of improving male reproductive function.The kidney-supplementing therapy of traditional Chinese medicine plays an irreplaceable role in the treatment of male reproductive function decline.The in-depth study of its therapeutic mechanism will provide guide for clinical practice and will supply theoretical basis for improving male reproductive function decline.

Abstract: Objective To analyze the distribution characteristics of the main pathogens of HIV/AIDS patients with wound infections and provide basis for clinical diagnosis and treatment. Methods The clinical data of 294 patients with positive secretions or pus specimens from 2016 to 2020 were analyzed retrospectively. Results A total of 357 strains of pathogenic bacteria were isolated from 294 cases, of which 123 strains of Gram-negative bacilli (G-b), accounting for 34.5%, were mainly Escherichia coli (15.4%), Klebsiella pneumoniae (3.9%), and Pseudomonas aeruginosa (3.6%); Gram-positive bacilli (G+b) 14 strains, accounting for 3.9%; 108 Gram-positive cocci (G+c), accounting for 30.3%, of which 44 strains were coagulase-positive Staphylococcus aureus (12.3%), Coagulase-negative staphylococci were mainly Staphylococcus epidermidis (4.2%) and Staphylococcus hemolyticus (2.8%); 37 strains of fungi, accounting for 10.4%, were mainly Candida albicans (5.9%); 75 strains of Mycobacterium, accounting for 21.0%, including 41 strains of Mycobacterium tuberculosis (11.5%) and 34 strains of non-tuberculosis mycobacteria (9.5%). 52 of the 294 HIV/AIDS patients had mixed infections, accounting for 17.7%. There was significant difference in the distribution of G+c, G-b, mycobacteria and mixed infection among different specimen sources (P<0.05), and there was significant difference in the distribution of mycobacteria among different CD4+T lymphocyte counts (P<0.05). There was significant difference in the level of CD4+T lymphocytes between patients of different ages (P<0.05), and there was significant difference in the level of CD4+T lymphocytes from postoperative incision and other parts (P<0.05). Conclusions Patients with HIV/AIDS are prone to combined wound infections with various pathogenic bacteria. We should strengthen the research on wound infection in HIV/AIDS patients, and timely send patients with a low number of CD4+T lymphocytes for secretion or pus culture, so as to carry out targeted treatment and improve the prognosis of patients.

OBJECTIVE:
To explore whether the ethanol extract of Herpetospermum caudigerum Wall (EHC), a Xizang medicinal plant traditionally used for treating liver diseases, can improve imiquimod-induced psoriasis-like skin inflammation.
METHODS:
Immunohistochemistry and immunofluorescence staining were used to determine the effects of topical EHC use in vivo on the skin pathology of imiquimod-induced psoriasis in mice. The protein levels of interferon-γ (IFN-γ), tumor necrosis factor-α (TNF-α), and interleukin-17A (IL-17A) in mouse skin samples were examined using immunohistochemical staining. In vitro, IFN-γ-induced HaCaT cells with or without EHC treatment were used to evaluate the expression of keratinocyte-derived intercellular cell adhesion molecule-1 (ICAM-1) and chemokine CXC ligand 9 (CXCL9) using Western blotting and reverse transcription-quantitative polymerase chain reaction. The protein synthesis inhibitor cycloheximide and proteasome inhibitor MG132 were utilized to validate the EHC-mediated mechanism underlying degradation of ICAM-1 and CXCL9.
RESULTS:
EHC improved inflammation in the imiquimod-induced psoriasis mouse model and reduced the levels of IFN-γ, TNF-α, and IL-17A in psoriatic lesions. Treatment with EHC also suppressed ICAM-1 and CXCL9 in epidermal keratinocytes. Further mechanistic studies revealed that EHC suppressed keratinocyte-derived ICAM-1 and CXCL9 by promoting ubiquitin-proteasome-mediated protein degradation rather than transcriptional repression. Seven primary compounds including ehletianol C, dehydrodiconiferyl alcohol, herpetrione, herpetin, herpetotriol, herpetetrone and herpetetrol were identified from the EHC using ultra-performance liquid chromatography-quadrupole-time of flight-mass spectrometry.
CONCLUSION
Topical application of EHC ameliorates psoriasis-like skin symptoms and improves the inflammation at the lesion sites.

Objective: To compare the effect of direct surgery or surgery after second-line chemotherapy for colorectal cancer patients with liver metastases who did not achieve objective remission after neoadjuvant chemotherapy. Methods: A retrospective case cohort study was used. The clinical and pathological data of 107 patients with colorectal cancer liver metastases who did not achieve objective response to neoadjuvant chemotherapy at Department of Hepatobiliary Surgery,Cancer Hospital,Chinese Academy of Medical Sciences from December 2008 to December 2016 were retrospectively collected. There were 71 males and 36 females, median age was 57 years (range: 28 to 79 years). According to the different treatment regimens after neoadjuvant chemotherapy,107 cases were divided into a direct surgery group (direct group,n=65) and an operation after receiving second-line chemotherapy group (second-line group,n=42). The propensity score matching(PSM) of the Logistic regression model was used to match the bilobar distribution of liver metastases and the number of first-line chemotherapy cycles in the two groups of patients. The caliper value was set to 0.10 and the matching ratio was 1∶2. T test, Mann-Whitney U test, χ2 test or Fisher's exat test was used to analyzed the data between the tuo groups, respectively. Survival analysis design was used to investigate the difference in prognosis between the two groups of patients. Results: The follow-up time(M(IQR)) was 56.3(34.3) months (range: 2.1 to 95.0 months),and all patients were followed up. After PSM,there were 28 cases in the direct group and 42 cases in the second-line group, there were no significant differences in whether R0 resection was feasible,blood loss,blood transfusion,postoperative complications and postoperative hospital stay between the two groups (all P>0.05). The 1,3,and 5-year progression-free survival(PFS) rates of the direct group were 40.0%,16.5%,and 11.0%,and the 1,3,and 5-year overall survival(OS) rates were 98.5%,61.2%,and 41.4%,respectively, the second-line group 1,3,5 years PFS rates were 35.7%,14.3%,14.3%,1,3,5-year OS rate were 95.2%,55.1%,44.4%,respectively. The median PFS time of the direct group and the second-line group was 8.5 months and 7.5 months,respectively,and the difference was not statistically significant (P=0.826). The median OS time of the direct group and the second-line group were 33.8 months and 46.9 months,respectively. The difference was not statistically significant(P=0.646).The median PFS time of the direct group and second-line chemotherapy complete remission and partial remission group(CR/PR group) was 10.2 months and 9.1 months,respectively,and the difference was not statistically significant(P=0.669). The median OS time of the direct group and the second-line CR/PR group was 51.0 months and 46.9 months,respectively,and the difference was not statistically significant(P=0.427). The results of survival analysis suggested that major liver resection was an independent prognosis factor for PFS (HR=1.809,95%CI: 1.067 to 3.067,P=0.028) and OS(HR=2.751,95%CI: 1.317 to 5.747,P=0.007). Second-line chemotherapy was not an independent prognostic factor for PFS (HR=0.945, 95%CI:0.570 to 1.567,P=0.828) and OS (HR=0.866,95%CI: 0.468 to 1.602,P=0.646). Conclusions: There is no significant difference in the short-term outcome and long-term prognosis between direct surgery patients and second-line chemotherapy followed by surgery. Second-line chemotherapy is not an independent prognostic factor for colorectal cancer liver metastases patients who fail to achieve objective response after neoadjuvant chemotherapy.

Background:
and Purpose Intracranial hemorrhage (ICH) is thought to be a rare but probably underestimated presentation of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). We conducted a systematic review and meta-analysis with the aim of comprehensively revealing the occurrence of ICH in patients with CADASIL.
Methods:
English-language studies published up to September 30, 2021 were searched for in the MEDLINE (PubMed), Web of Science, and Cochrane Library databases. The design, patient characteristics, occurrence rate of ICH, and associated risk factors were retrieved for each identified relevant study.
Results:
We enrolled 13 studies in the final meta-analysis, which included 1,310 patients with CADASIL. The probability of ICH occurrence in patients with CADASIL was 10.1% (95% confidence interval [CI]=5.6%–18.0%, I2 =85.1%). When stratified by geographic region, the occurrence rate of ICH was much higher in Asians (17.7%; 95% CI=11.0%–28.5%, I2 =76.3%) than in Europeans (2.0%; 95% CI=0.4%–10.8%, I2 =82.8%). A higher burden of cerebral microbleeds (CMBs) and a history of hypertension were the most commonly recorded risk factors for ICH, which were available for three and two of the included studies, respectively.
Conclusions
Our study suggests that ICH is an important clinical manifestation of CADASIL, especially in Asians. A higher burden of CMBs and the existence of hypertension were found to be associated with a higher probability of ICH occurrence in patients with CADASIL.

Ginkgo biloba Extract( GBE50) Dispersible Tablets is a new standardized prescription,which is widely used in the treatment of ischemic cardiovascular and cerebrovascular diseases. However,there are still many problems in its clinical application.Rational and safe use of GBE50 Dispersible Tablets is pivotal to the medication safety and clinical prognosis of patients. This consensus has been jointly formulated by clinical experts of traditional Chinese medicine and western medicine in cardiovascular and cerebrovascular diseases and followed the Manual for the Clinical Experts Consensus of Chinese Patent Medicine published by the China Association of Chinese Medicine. The present study identified clinical problems based on clinical investigation,searched the research papers according to PICO clinical problems,carried out evidence evaluation,classification,and recommendation by GRADE system,and reached the expert consensus with nominal group technique. The consensus combines evidence with expert experience. Sufficient evidence of clinical problems corresponds to " recommendations",while insufficient evidence to " suggestions". Safety issues of GBE50 Dispersible Tablets,such as indications,usage and dosage,and medication for special populations,are defined to improve clinical efficacy,promote rational medication,and reduce drug risks. This consensus needs to be revised based on emerging clinical issues and evidencebased updates in practical applications in the future.

Vascular endothelial cells and oxidation reduction system play an important role in the pathogenesis of atherosclerosis (AS). If these conditions are disordered, it will inevitably lead to plaque formation and even rupture. Astragaloside IV (AsIV) and salvianolic acid B (Sal B) are the main active ingredients of Astragalus membranaceus and Salvia miltiorrhiza, respectively, and found to ameliorate vascular endothelial dysfunction and protect against oxidative stress in recent studies. However, it is still unknown if the combination of AsIV and Sal B (AsIV + Sal B) can inhibit the development of plaque through amplifying the protective effect of vascular endothelial cells and anti-oxidative stress effect. To clarify the role of AsIV + Sal B in AS, we observed the efficacy of each group (Control, Model, AsIV, Sal B, and AsIV + Sal B) by biomolecular assays, such as observing the pathological morphology of the aorta by oil red O staining, evaluating the level of oxidative stress and endothelial cells in the serum by the Elisa test, and analyzing the changes of all small molecule metabolites in liver tissue by UPLC-QTOF-MS. Results showed that AsIV, Sal B and AsIV + Sal B decreased the deposition of lipid in the arterial wall, so as to exert the effect of anti-oxidant stress and vascular endothelial protection, where the inhibitory effect of AsIV + Sal B was the most obvious. Metabonomics analysis showed that Sal B regulated the metabolic pathways of arginine and proline. AsIV regulated glycerol metabolism and saturated fatty acid biosynthesis metabolism. AsIV + Sal B is mainly related to the regulation of the citrate cycle (TCA cycle), alanine, aspartic acid, and glutamate metabolism, cysteine, and methionine metabolism. Succinic acid and methionine are synergistic metabolites that exert an enhancing effect when AsIV and Sal B were used in combination. In conclusion, we demonstrated that AsIV acompanied with Sal B can be successfully used for anti-oxidative stress and vascular endothelial protection of AS, and succinic acid and methionine are the synergistic metabolites.
