[Analysis of traditional Chinese medicine diagnosis and treatment for erectile dysfunction related to COVID-19 infection].

The incidence of erectile dysfunction (ED) has been reported to increase after COVID-19 infection, and it is common in COVID-19 patients during recovery. This paper presents a summary of the latest research progress on COVID-19-induced ED and explores the traditional Chinese medicine (TCM) diagnosis and treatment approach based on TCM theory and clinical experience. COVID-19 infection may lead to ED through endothelial dysfunction, testicular injury, hormonal imbalance, and psychological factors. The pathogenesis of COVID-19-related ED is mainly characterized by deficiency of the body's essence and excess of pathogenic factors. In the early stage, it is dominated by deficiency of qi and yin, while in the middle stage, it is mainly due to deficiency of qi and blood stasis. In the long-term, ED is based on the imbalance of yin and yang, with liver stagnation and qi stagnation often co-existing. Clinical manifestations of ED vary, and treatment should focus on tonifying qi and nourishing yin, promoting blood circulation, regulating yin and yang, and soothing liver depression according to TCM diagnosis and treatment principles.

Reduced SARS-CoV-2 infection risk is associated with the use of Seven-Flavor Herb Tea: A multi-center observational study in Shanghai, China / 中西医结合学报

OBJECTIVE@#Omicron, a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant, is responsible for numerous infections in China. This study investigates the association between the use of Seven-Flavor Herb Tea (SFHT) and the risk of SARS-CoV-2 infection to develop precise and differentiated strategies for control of the coronavirus disease 2019 (COVID-19).@*METHODS@#This case-control study was conducted at shelter hospitals and quarantine hotels in China. A total of 5348 laboratory-confirmed COVID-19 patients were enrolled between April 1 and May 31, 2022, while 2190 uninfected individuals served as healthy controls. Structured questionnaires were used to collect data on demographics, underlying diseases, vaccination status, and use of SFHT. Patients were propensity-score-matched using 1:1 nearest-neighbor matching of the logit of the propensity score. Subsequently, a conditional logistic regression model was used for data analysis.@*RESULTS@#Overall, 7538 eligible subjects were recruited, with an average age of [45.54 ± 16.94] years. The age of COVID-19 patients was significantly higher than that of uninfected individuals ([48.25 ± 17.48] years vs [38.92 ± 13.41] years; t = 22.437, P < 0.001). A total of 2190 COVID-19 cases were matched with uninfected individuals at a 1:1 ratio. The use of SFHT (odds ratio = 0.753, 95% confidence interval: 0.692, 0.820) was associated with a lower risk of SARS-CoV-2 infection compared to untreated individuals.@*CONCLUSION@#Our findings suggest that taking SFHT reduces the risk of SARS-CoV-2 infection. This is a useful study in the larger picture of COVID-19 management, but data from large-sample multi-center, randomized clinical trial are warranted to confirm the finding.

[Professor LIN Guo-hua's experience in the clinical application of "Dayingxiang"].

The paper introduces professor LIN Guo-hua's experience in treatment with acupuncture-moxibustion at "Dayingxiang". Based on the application of Neiyingxiang (internal LI 20), professor LIN defines the entire nasal cavity and its adjacent nasopharynx as "Dayingxiang", of which, "Neiyingxiang" and "Biyandian" (nasopharynx point) are commonly stimulated with acupuncture-moxibustion. "Dayingxiang" may regulate lung qi and promote the circulation of the marrow sea in treatment of the disorders of lung system and the marrow. Fire needling with twirling or burning-scallion technique is predominated in manipulation. "Neiyingxiang" is stimulated for the shallow-located disorders, while, "Biyandian" is for the deep-located ones. These two points are optioned alternatively or in combination to enhance the therapeutic effect.

The In Vitro Effect of Psoralen on Glioma Based on Network Pharmacology and Potential Target Research.

Glioma is an aggressive tumor, currently there is no satisfactory management available. Psoralen, as a natural product, has been found to have an effect of treating cancer in recent years, but its effect on glioma has not been explored. In this study, we investigated the in vitro inhibition effect and potential targets of psoralen on glioma through network pharmacology and in vitro glioma treatment experiments. First, we used network pharmacology to preliminarily predict the 21 core genes of psoralen in the treatment of glioma, including PIK3CA, PIK3CB, PIK3CG, and JAK2. The CCK-8 method was used to detect the effect of psoralen on the proliferation of glioma U87 and U251 cells, and the results showed that psoralen could significantly inhibit the proliferation of U87 and U251 cells. The flow cytometry was used to detect the apoptosis and cell cycle changes, and it was found that psoralen could significantly promote the early apoptosis of U87 and U251 cells and had a significant cycle arrest effect on the two cells. The cell scratch test showed that psoralen could significantly inhibit the migration of U87 and U251 cells. The relative expression levels of PIK3CA, PIK3CB, PIK3CG, and JAK2 were analyzed by Real-time Quantitative polymerase chain reaction (QT-PCR), and the results showed that psoralen could inhibit the gene expression of PIK3CA, PIK3CB, PIK3CG, and JAK2. Later, Western blotting (WB) experiments showed that psoralen could inhibit the protein expressions of PI3K and JAK2. This study has preliminarily explored and verified the antiglioma effect of psoralen in the form of inhibiting cell proliferation and migration, promoting cell apoptosis and organizing cell cycle in vitro. And may play a role by inhibiting the expression of PIK3CA, PIK3CB, PIK3CG, JAK2 gene and PI3K, JAK2 protein, psoralen has become a potential antiglioma drug.

Effect of Antioxidants Supplementation on Erectile Dysfunction: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

INTRODUCTION: In Erectile dysfunction (ED) patients, phosphodiesterase type 5 (PDE5) inhibitors are considered as the first-line therapy. However, 30-50% of ED patients fail to follow this therapeutic option because of adverse events, lack of efficacy, or drug costs. Antioxidant supplementation is widely applied in clinical practice and viewed as a potential therapeutic option for ED. Therefore, it is attractive to assess the effect of antioxidants supplementation on ED patients. OBJECTIVES: To evaluate the effects of antioxidants supplementation on ED. METHODS: Published randomized controlled trials of antioxidants in ED were searched in the PubMed, Embase, and Cochrane Library databases from inception to October 3, 2021. Meta-analyses were carried out using a random-effects model. The results were presented as standard mean differences (SMDs) with their 95% confidence intervals (CIs). RESULTS: Eighteen studies with 1,331 ED patients were included in the study. Compared with placebo, antioxidants alone treatment showed a statistical increase in International Index of Erectile Function (IIEF) score (SMD = 1.93; 95% CI: 0.15, 3.72; P = .034). Compared with placebo, antioxidants compound treatment elicited a significant increase in IIEF score (SMD = 2.74; 95% CI: 1.67, 3.81; P < .001) as well as sexual satisfaction score (SMD = 1.61; 95% CI: 0.63, 2.59; P = .001). Compared with the PDE5 inhibitors alone, combination of PDE5 inhibitors and antioxidants showed a significant increase in IIEF score (SMD = 1.1; 95% CI: 0.51, 1.68; P < .001) and sexual satisfaction score (SMD = 1.28; 95% CI: 0.06, 2.51; P = .04). CONCLUSION: This study found that the effect of antioxidant alone treatment on ED may be limited. However, antioxidant compound treatment, as well as combination of PDE5 inhibitors and antioxidants, were associated with improved ED, and can be considered as an accessary therapeutic option for ED.

Complementary Copper-Catalyzed and Electrochemical Aminosulfonylation of O-Homoallyl Benzimidates and N-Alkenyl Amidines with Sodium Sulfinates.

A complementary copper-catalyzed and electrochemical aminosulfonylation of O-homoallyl benzimidates and N-alkenyl amidines with sodium sulfinates was developed. The terminal alkene substrate produced sulfone-containing 1,3-oxazines and tetrahydropyrimidines in the presence of Cu(OAc)2, Ag2CO3, and DPP, and under similar reaction conditions, sulfonylated tetrahydro-1,3-oxazepines were prepared from 1-aryl-substituted O-homoallyl benzimidates in moderate to good yields. For certain electron-rich 1,1-diaryl-substituted alkene substrates, the corresponding tetrahydro-1,3-oxazepines could also be obtained in similar or even higher yields via a green electrochemical technique.

[Professor LIN Guo-hua's clinical experience in staging treatment for post-stroke dysphagia].

The paper summarizes professor LIN Guo-hua's clinical experience in staging treatment for post-stroke dysphagia. Professor LIN Guo-hua adheres to "essence and marrow deficiency and primary yang decline" as the pathogenesis and "conducting yin from yang " as the treating principle. By regulating the conception vessel and the governor vessel and focusing on yang meridians, in association with meridian differentiation and the location differentiation, professor LIN provides the staging treatment for post-stroke dysphagia. At the oral phase, yangming is dysfunction, manifested as facial paralysis and flaccid tongue. In treatment, reducing method is predominated at yangming meridian specially. At the pharyngeal phase, shaoyang is invaded by pathogens, manifested as pivoting dysfunction. The treatment focuses on communicating the exterior with the interior and promoting shaoyang meridian. At the esophageal phase, yangming meridian is deficiency and the turbid qi fails to descend, thus the reinforcing method is dominated to promote and tonify yangming. Additionally, the kinesiotherapy of acupuncture is assisted and the Lingnan fire needling therapy is used particularly. All of the summaries above provide the reference for the clinical treatment of post-stroke dysphagia.

Effect of Antioxidants on Sperm Quality Parameters in Subfertile Men: A Systematic Review and Network Meta-Analysis of Randomized Controlled Trials.

Antioxidant supplementation has been identified as an important intervention for subfertile men. However, the effectiveness of different antioxidants in improving sperm quality remains unclear. In this study, a network meta-analysis (NMA) was designed to evaluate the effects of different antioxidants on sperm quality parameters in subfertile men. Published randomized controlled trials (RCTs) of antioxidants in subfertile men were searched in the PubMed, Embase, and Cochrane Library databases from inception to 31 January, 2021. Eight antioxidants (folic acid, zinc, vitamin E, carnitine, selenium, coenzyme q10 [CoQ10], N-acetylcysteine, and vitamin C) and a placebo (control) were included in our study. A Bayesian NMA with random effects was performed for each outcome (sperm concentration, sperm motility, and sperm morphology); the surface under the cumulative ranking curves (SUCRAs) for the effectiveness of each intervention was applied to identify the optimal intervention. Eighteen studies with 1790 subfertile men were included in the study. CoQ10 elicited a significant increase in sperm concentration (mean difference [MD] = 5.95; 95% CI: 0.05, 10.79) compared with the placebo; it achieved the highest rank in efficacy among all the antioxidants (SUCRA: 79.4%). With regard to sperm motility, carnitine (MD = 12.43; 95% CI: 4.07, 20.26) and CoQ10 (MD = 7.33; 95% CI: 0.35, 14.17) showed significant beneficial effects compared with the placebo; the efficacy of carnitine was the highest among all the antioxidants (SUCRA: 88.7%). With regard to sperm morphology, the efficacy of vitamin C tended to be the highest (SUCRA: 93.6%), although it did not show a significant beneficial effect (MD = 7.73; 95% CI: -0.94, 16.33) compared with the placebo. Overall, for subfertile men, CoQ10 and carnitine interventions showed better effectiveness in increasing sperm concentration and sperm motility, respectively.

[ZHANG Jia-wei's experience for treating press ulcer with fire-moxibustion].

To summarize ZHANG Jia-wei 's experience for treating press ulcer with fire-moxibustion. Through syndrome differentiation and examined factors, ZHANG Jia-wei believes that the disease is caused by qi deficiency and blood stasis, and advocates that the treatment should be weighed against deficiency and excess, and selection by stages. The cotton-moxibustion is used to diffusing and obstruction-removing qi and blood duingⅠstage of press ulcer. The Lingnan fire-needling is adopted for removing dampness, blood stasis and toxic substance to generate new muscles duringⅡand Ⅲ stage of press ulcer. Stage Ⅳof pressure ulcer and deep pressure ulcer should be treated with Taiyi moxa stick and aconite cake-separated moxibustion combined or alternately to expel toxin and grow muscles.

[Professor LIN Guo-hua's experience in treating intractable sudden deafness with acupuncture and moxibustion].

Professor LIN Guo-hua's experience and medical record in the treatment of intractable sudden deafness with acupuncture is introduced. Professor LIN believes that this disease is mainly caused by the blockage of shaoyang meridians, and should be treated with acupuncture therapy as soon as possible. According to the root cause and the pathogenesis of shaoyang blockage, the method of "soothing shaoyang, clearing the ear and opening the orifices" is adopted. In the treatment, Tinggong (SI 19) and acupoints in shaoyang meridians are selected as the main acupoints, and other acupoints based on meridian differentiation are selected as assisting acupoints. The manipulatingmethods of "fameng acupuncture" "blowing warm air into ear", and "Lingnan fire needling" are used synthetically. And qi and spirit are also regulated and front mu points are added if necessary to obtain satisfied effect of restore hearing.

A large dose of methamphetamine inhibits drug­evoked synaptic plasticity via ER stress in the hippocampus.

Drug addiction is a chronic and recurrent disease associated with learning and memory. Shaped by drug use and cues from the environment, drug memory serves a key role in drug­seeking behaviour. Methamphetamine (MA), a globally abused drug, causes cognitive impairment, and endoplasmic reticulum (ER) stress is one of the mechanisms via which this occurs. In the current study, it was hypothesized that ER stress may serve a role in the disturbance of drug memory. The present study demonstrated that 5 mg/kg MA inhibited conditioned place preference behaviour via ER stress, which caused a disruption in long­term potentiation in the hippocampus. When mice were pre­treated with the ER stress inhibitors 4­phenyl butyric acid or tauroursodeoxycholic acid, drug­evoked synaptic plasticity was induced. Western blotting results indicated that treatment with 5 mg/kg MA enhanced the expression of cyclin­dependent kinase­5 and decreased the expression of Ca2+/calmodulin­dependent protein kinase II α via ER stress. Collectively, the present results suggested that a large dose of MA inhibited drug­evoked synaptic plasticity and disrupted drug memory by inducing ER stress.

[An in vitro study on metabolic interaction between main active components of Salviae Miltiorrhizae Radix et Rhizoma and tacrolimus].

The purpose of this study was to investigate the inhibitory effects of the main active components of Salviae Miltiorrhizae Radix et Rhizoma on the metabolism of tacrolimus mediated by CYP3 A4/5 enzyme, so as to predict the potential drug-drug interaction(DDI) in clinical use. First, the reversible inhibitory activities of five active components of Salviae Miltiorrhizae Radix et Rhizoma(tanshinone Ⅰ, tanshinone Ⅱ_A, cryptotanshinone, salvianolic acid B, dihydrotanshinone Ⅰ) on the metabolism of tacrolimus was investigated by using human liver microsomes(HLM) and recombinant human CYP3 A4/5 enzyme in vitro, then the dose-dependent inhibition of CYP3 A4/5 activity was calculated in HLM. Finally, the time-dependent inhibition(TDI) activities of five active components were studied in HLM through the robust single point inhibition test. In addition, a simple and rapid liquid chromatography tandem mass spectrometry method(HPLC-MS/MS) for the determination of tacrolimus was established in this study. The results showed that dihydrotanshinone Ⅰ had a strong inhibitory effect on the metabolism of tacrolimus in both HLM and rCYP3 A4/5 enzyme systems, and the inhibitory potential IC_(50) in HLM was 6.0 µmol·L~(-1), while the other four active components of Salviae Miltiorrhizae Radix et Rhizoma exhibited relatively weak inhibition on CYP3 A4/5 activity with inhibition rate less than 30% at 10 µmol·L~(-1). Furthermore, the TDI activity of five active components of Salviae Miltiorrhizae Radix et Rhizoma at 50 µmol·L~(-1) was 5.5%-15.9%. The above results suggested that clinical DDI between tacrolimus and Salviae Miltiorrhizae Radix et Rhizoma may occur when the active components of Salviae Miltiorrhizae Radix et Rhizoma achieved a relative high concentration in human. In conclusion, this study provided a data reference for the research on drug interaction of tacrolimus and Salviae Miltiorrhizae Radix et Rhizoma as well as rational drug use in clinical practice.

[Professor LIN Guo-hua's experience in the new clinical application of Yinjiao (GV 28)].

Yinjiao (GV 28) is generally used in treatment of lumbago and anorectal diseases. Professor LIN Guo-hua believes that Yinjiao (GV 28) is indicated in the disorders related to the sea of marrow and lower jiao by regulating the governor vessel and the conception vessel, promoting qi and blood circulation, tonifying the sea of marrow and adjusting the lower jiao. Based on professor Lin's clinical experience, "three Yinjiao" points are innovated, named Yinjiao (GV 28, upper Yinjiao), external Yinjiao and lower Yinjiao. Acupuncture therapy is generally optioned at Yinjiao (GV 28) and 5 needling principles are emphasized, i.e. accurate acupoint location, strong needling sensation, needling combined with body movement, alternative stimulation and allied stimulation. All of those mentioned above provide a new approach to the clinical treatment for the disorders related to the sea of marrow and lower jiao.

[Exploration of fire needling therapy on coronavirus disease 2019].

Combined with previous clinical experience in anti-epidemic and acupuncture, the prevention program of fire needling therapy for coronavirus disease 2019 (COVID-19) was drawn out. Fire needling therapy has the effects of clearing heat, removing dampness, replenishing for the deficiency, removing stasis and detoxifying, which is mainly aimed at preventing populations, light and common types cases, and cases in the recovery period. Acupoints of governor vessel, lung meridian, bladder meridian and stomach meridian are mainly used in this program. For the special groups, such as children, elderly and weak, and pregnant women, Shenzhu (GV 12), Danshu (BL 19), Geshu (BL 17), Zhigou (TE 6), etc. are added. It is hoped that fire needling therapy will be applied in the community and square cabin hospitals as an effective supplement to anti-epidemic of traditional Chinese medicine (TCM).

[Professor LIN Guo-hua's clinical experience of acupuncture for oculomotor nerve paralysis].

Professor LIN Guo-hua's clinical experience of acupuncture for oculomotor nerve palsy was summarized and one typical case was introduced. Professor LIN skillfully applied traditional acupuncture theory and classical acupuncture method, and proposed a diagnosis and treatment system combining meridian syndrome differentiation and specific acupuncture techniques. In addition, Professor LIN combined the yuan-primary and luo-connecting acupoints combination method, theory of "removing the stagnation of blood and qi " and theory of root-stem and origin-end, etc. into the treatment of oculomotor nerve palsy, and achieved good results.

[Professor LIN Guo-hua's experience in treatment of progressive muscular dystrophy with acupuncture].

Professor LIN Guo-hua's experience is introduced in treatment of progressive muscular dystrophy with acupuncture. It is believed that the pathogenesis of this disease is related to spleen and kidney deficiency, qi and blood insufficiency and malnutrition of tendon and muscle. The treatment is determined in terms of the pathogenesis and focuses on the regulation of spleen and kidney functions. The thinking of treatment is summarized as exerting the strong stimulation of acupuncture specially at the acupoints on the head, supplementing the sea of marrow, adjusting simultaneously the three yang meridians, rather than treating particularly yangming meridian and regulating qi in priority and considering the lung function for wei (flaccid) syndrome. Moreover, in clinical treatment, the acupoint thread-embedding therapy is commonly combined to ensure the significant therapeutic effect.
