Premature ejaculation refers to a sexual dysfunction in which men experience a short intravaginal ejaculation latency and a lack of control over ejaculation during sexual activity. The onset of this condition is often accompanied by anxiety and depression, which can seriously affect the quality of the patient′s sexual life and the relationship between partners. Based on the "integration of body and spirit" theory in traditional Chinese medicine, our team believes that this condition is a comorbidity of physical and spiritual factors. We propose that the core pathogenesis of this disease lies in the "loss of form and essence, impairment of spirit, and depression of the mind, "while the primary treatment principle involves "nourishing form and regulating spirit." As a result, a new diagnosis and treatment approach of "four-dimensional integration" is summarized in this study. The disease is treated through the four dimensions of shape, body, spirit, and emotion. Traditional Chinese medicine is used to adjust the shape in cases where the physical form is damaged. For individuals with depression of heart and liver qi, the treatment focuses on soothing the heart and smoothing liver qi, and the modified Wangyou Powder and Xuanzhi Decoction is used. In cases where the heart and kidney function are compromised, the treatment involves nourishing both the heart and kidney while restoring interaction between the heart and the kidney, and modified Jihuo Yansi Elixir is used. To reduce the sensitivity of the glans penis, the patient′s body is washed with a traditional Chinese medicine formula, and a delicate fumigation formula is decocted for external washing. For those who are not in tune with their god, psychological counseling can be used to regulate their spirit and advocate "self-partner" and psychotherapy. If there are issues with intimacy, partners should focus on cooperating during foreplay, sexual intercourse, and post-coital interactions. Overall, the treatment aims to harmonize the body and spirit, addressing both physical and psychological factors through a comprehensive, multi-dimensional approach. This method provides new perspectives and ideas for the clinical diagnosis and treatment of this condition.

Objective To observe the efficacy and safety of Morinda officinalis oligosaccharides in the continuation treatment of mild and moderate depression.Methods An open,single-arm,multi-center design was adopted in our study.Adult patients with mild and moderate depression who had received acute treatment of Morinda officinalis oligosaccharides were enrolled and continue to receive Morinda officinalis oligosaccharides capsules for 24 weeks,the dose remained unchanged during continuation treatment.The remission rate,recurrence rate,recurrence time,and the change from baseline to endpoint of Hamilton Depression Scale(HAMD),Hamilton Anxiety Scale(HAMA),Clinical Global Impression-Severity(CGI-S)and Arizona Sexual Experience Scale(ASEX)were evaluated.The incidence of treatment-related adverse events was reported.Results The scores of HAMD-17 at baseline and after treatment were 6.60±1.87 and 5.85±4.18,scores of HAMA were 6.36±3.02 and 4.93±3.09,scores of CGI-S were 1.49±0.56 and 1.29±0.81,scores of ASEX were 15.92±4.72 and 15.57±5.26,with significant difference(P＜0.05).After continuation treatment,the remission rate was 54.59％(202 cases/370 cases),and the recurrence rate was 6.49％(24 cases/370 cases),the recurrence time was(64.67±42.47)days.The incidence of treatment-related adverse events was 15.35％(64 cases/417 cases).Conclusion Morinda officinalis oligosaccharides capsules can be effectively used for the continuation treatment of mild and moderate depression,and are well tolerated and safe.

Objective:To investigate the effects of Wenpi Tongluo Kaiqiao Prescription combined with scalp acupuncture on the expression levels of hippocampal autophagy markers Beclin1, P62 and MAP1-LC3 in Alzheimer's disease (AD) model rats.Methods:The AD rat model was established by stereotactic drug injection, and randomly divided into model group, acupuncture-medicine group, and Western medicine group. Sham-operation group and control group were set, with 10 rats in each group. The acupuncture-medicine group was treated with scalp acupuncture plus Wenpi Tongluo Kaiqiao Prescription (16.8 g/kg); the Western medicine group was treated with donepezil hydrochloride tablets (0.08 mg/kg in week 1, 0.16 mg/kg in week 2, 0.24 mg/kg in week 3, 0.32 mg/kg in week 4) for gavage. The sham-operation group, the control group and the model group were treated with equal volume of normal saline for gavage. The drug was administered 2 weeks after modeling. Morris water maze was used to test the learning and memory abilities of rats in each group after continuous administration for 4 weeks, and the hippocampus of the animal was taken after Morris water maze. HE staining and TUNEL staining were used to observe the pathological changes of the hippocampal CA1 region in each group. Western blot was used to detect the expression levels of Beclin1, P62 and MAP1-LC3 protein genes.Results:Compared with the model group, the escape latency of rats in the acupuncture-medicine group and Western medicine groups was significantly shortened ( P<0.05), and the number of times they crossed the platform increased ( P<0.05). The HE and TUNEL results indicated that the model group rats had abnormal tissue structure and cell morphology in the CA1 area of the hippocampus, with significant cell degeneration. There were more autophagic vesicles in the cytoplasm of hippocampal neurons, and the structure of autophagic lysosomes was clear and complete; the tissue structure, cell morphology, and cellular degeneration of the CA1 area in the hippocampus of rats treated with acupuncture and medicine were significantly improved. The percentage of cell apoptosis in the acupuncture-medicine group and Western medicine group decreased ( P<0.05), the expression of Beclin1 protein in hippocampal tissue increased, and the expressions of MAP1-LC3 and P62 proteins decreased ( P<0.05). Conclusion:Wenpi Tongluo Kaiqiao Prescription combined with scalp acupuncture can suppress the apoptosis of hippocampal CA1 neurons, promote cognitive and memory recovery in AD rats by promoting the expression of Beclin1 in the hippocampus, inhibiting the expression of P62 and LC3, enhancing autophagy levels, and increasing autophagic activity.

Objective: To investigate the clinical features of coronavirus disease 2019 (COVID-19) in patients with aplastic anemia (AA) undergoing immunosuppressive therapy (IST) . Methods: In this prospective cohort study, we collected the demographic and clinical data of patients with AA and COVID-19 from December 1, 2022, to January 31, 2023. We described the clinical features of COVID-19 among patients with AA and evaluated the effects of IST on the signs and severity of COVID-19. Results: A total of 170 patients with AA and COVID-19 were included. The common early symptoms, including fever, dizziness or headache, muscle or body aches, and sore throat, disappeared within 1-2 weeks. Approximately 25% of the patients had persistent fatigue within 2 weeks. Many patients experienced cough after an initial 1-3 days of infection, which lasted for more than 2 weeks. There were no differences in the duration of total fever episodes and maximum body temperature when patients were stratified according to whether or not they underwent IST, by IST duration, or by use of anti-lymphocyte globulin (ALG) (P>0.05). No differences were observed in the occurrence of symptoms in either the early or recovery stages when patients with AA were stratified according to whether or not they underwent IST, or by IST duration (P>0.05). However, patients who received ALG had fewer fever episodes within 1 week after infection (P=0.035) and more sore throat episodes within 2 weeks after infection (P=0.015). There were no other significant differences in clinical symptoms between patients who did and patients who did not receive ALG (P>0.05) . Conclusion: The majority of patients with AA and COVID-19 recovered within 2 weeks of noticing symptoms when treated with IST.

It is an urgent demand worldwide to control the coronavirus disease 2019 (COVID-19) pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus. The 3-chymotrypsin-like protease (3CL^pro) and papain-like protease (PL^pro) are key targets to discover SARS-CoV-2 inhibitors. After screening 12 Chinese herbal medicines and 125 compounds from licorice, we found that a popular natural product schaftoside inhibited 3CL^pro and PL^pro with IC₅₀ values of 1.73 ± 0.22 and 3.91 ± 0.19 μmol/L, respectively, and inhibited SARS-CoV-2 virus in Vero E6 cells with EC₅₀ of 11.83 ± 3.23 μmol/L. Hydrogen-deuterium exchange mass spectrometry analysis, quantum mechanics/molecular mechanics calculations, together with site-directed mutagenesis indicated the antiviral activities of schaftoside were related with non-covalent interactions with H41, G143 and R188 of 3CL^pro, and K157, E167 and A246 of PL^pro. Moreover, proteomics analysis and cytokine assay revealed that schaftoside also regulated immune response and inflammation of the host cells. The anti-inflammatory activities of schaftoside were confirmed on lipopolysaccharide-induced acute lung injury mice. Schaftoside showed good safety and pharmacokinetic property, and could be a promising drug candidate for the prevention and treatment of COVID-19.

In this paper， the key technical problems in the research and development of famous classical formulas are analyzed. Firstly， the puzzled problem for a long-time， which is conversion relationship from medicinal metrology of Han dynasty （HD） to that of modern （gram，g）， is comprehensively expounded that one Liang （两） of HD=3 g is more appropriate. Secondly， the model and principles of quality consistency evaluation are given for the transformation from the quality of authoritative basic sample prepared by casserole （ABS-C） to the quality consistency in Laboratory process， pilot-scale process and industrial production. The consistency evaluation model is ξ_ABS-X=K₁（Q₁^ABS-X/Q₁^ABS-C）+K₂（Q₂^ABS-X/Q₂^ABS-C）+……+K_i（Q_i^ABS-X/Q_i^ABS-C）=∑K_i（Q_i^ABS-X/Q_i^ABS-C）（i=1，2，3……n）. In the formula， ABS-X means laboratory reference sample ABS-C （ABS-L）， pilot-scale ABS-C （ABS-mP） or industrial production ABS-C （ABS-P）， ξ_ABS-X means the quality consistency rate or similarity degree of ABS-L， ABS-mP and ABS-P processes with ABS-C， K_i means the weight of each quality evaluation index （i）， Q_i^ABS-X is the data of i in ABS-L， ABS-mP， ABS-P samples， and Q_i^ABS-C is the data （or mean） of i in ABS-C sample. Thirdly， in order to control the quality of the herbal medicines whose active ingredients were unknown， their chemical constituents should be studied deeply， and if necessary， the bioassay research should be carried out according to the main efficacy or indication of famous classical formulas. Finally， for the special processing of some herbal medicines， it is difficult to formulate the processing method， technology and standard of prepared slices. It is suggested that the scientific connotation and historical evolution of the special processing method should be thoroughly sorted out， and its technological characteristics are summarized， the modern processing technology and production processes are simulated， and then the corresponding processing methods and quality standards are formulated.

Objective: To investigate the feasibility of endoscopic lateral neck dissection via the breast and transoral approaches (ELNDBTOA) for papillary thyroid carcinoma (PTC). Methods: From February 2015 to April 2019, 10 patients with PTC (cN1b) including 1 male and 9 females aged from 22 to 53 years old received ELNDBTOA in the General Surgery Department of Zhongshan Hospital, Xiamen University. Total thyroidectomy, the central lymph node dissection and the selective neck dissection (levels Ⅱ, Ⅲ and Ⅳ) were performed endoscopically via the breast approach, and then the residual lymph nodes were dissected via transoral approach. The medical records, operation time, blood loss, complications and postoperative follow-up outcomes were analyzed retrospectively. SPSS 22.0 software package was used for statistical processing of clinical data of patients. Results: All cases were successfully treated with ELNDBTOA without transfer to open surgery. The average operative time was (362.5±79.7) min, the blood loss was (23.0±14.9) ml, and the postoperative hospital stay was (5.1±1.3) days. The mean number of harvested cervical lymph nodes were (34.2±25.8), and the mean number of positive lymph nodes were (6.5±4.9). Lymph nodes were dissected by the further dissection via oral approach in 6 patients and a total of 9 lateral lymph nodes were havested from 2 of the 6 patients, with 3 positive lymph nodes. Two patients had transient skin numbness in the mandibular area and recovered within two weeks. One patient developed transient hypoparathyroidism and recovered within two months. No secondary bleeding, recurrent laryngeal nerve paralysis, chylous leakage, neck infection, permanent hypoparathyroidism or other complications were observed. The follow-up time was from 16 to 66 months with a median of 42.5 months, no tumor recurrence or metastasis occurred, and also no obvious deformity, abnormal sensation or movement in the chest, neck and mouth was observed. Conclusions: ELNBTOA is safe and feasible, with good cosmetic outcome.

Lung cancer is a malignant tumor characterized by a rapid proliferation rate, less survivability, high mortality, and metastatic potential. This review focuses on updated research about the clinical application of traditional Chinese medicine (TCM) as an adjuvant therapy to lung cancer treatment and the mechanisms of TCM effect on lung cancer in vitro and in vivo. We summarized the recent 5 years of different research progress on clinical applications and antitumor mechanisms of TCM in the treatment of lung cancer. As a potent adjuvant therapy, TCM could enhance conventional treatments (chemotherapy, radiation therapy, and epidermal growth factor receptors [EGFRs] tyrosine kinase inhibitors [TKIs]) effects as well as provide synergistic effects, enhance chemotherapy drugs chemosensitivity, reverse drug resistance, reduce adverse reactions and toxicity, relieve patients' pain and improve quality of life (QOL). After treating with TCM, lung cancer cells will induce apoptosis and/or autophagy, suppress metastasis, impact immune reaction, and therapeutic effect of EGFR-TKIs. Therefore, TCM is a promisingly potent adjuvant therapy in the treatment of lung cancer and its multiple mechanisms are worthy of an in-depth study.

This study aimed to explore the main active ingredients and potential targets of Solanum nigrum(SN), so as to reveal the potential molecular mechanism of SN in the treatment of hepatocellular carcinoma(HCC) based on network pharmacology and molecular docking. First,the main active ingredients and predictive targets of SN were collected in the traditional Chinese medicine systems pharmacology database and analysis platform(TCMSP). Then,the targets relating to HCC were collected through retrieval of integrated bio-pharmacological network database for traditional Korean medicine(PharmDB-K), oncogenomic database of hepatocellular carcinoma(OncoDB.hcc). The common targets of disease-drug component were selected through intersection between predictive targets and disease targets. Next, based on the String platform, protein-protein interaction network(PPI) model of the potential anti-HCC targets was constructed using the software Cytoscape 3.7.1. ClueGO and CluePedia APP in Cytoscape were used to analyze the gene function of SN in the treatment of HCC, and construct the main active ingredients-potential targets-signal pathways topology network of SN. Finally,DISCOVERY STUDIO software was applied in verifying the molecular docking between the key active ingredient and potential protein target. The results showed that there were 4 main active ingredients of SN, involving 22 potential targets relating to HCC and 7 signal pathways relating to potential anti-HCC targets of SN. Network analysis showed that SN may play a therapeutic role in HCC by acting on key targets, such as EGFR, TP53, MYC, CCND1 and CTNNB1. Molecular docking results showed that quercetin and EGFR could bind stably and interact through amino acid residues LEU718, LYS745 and GLN791. This study revealed the potential active ingredients and the possible molecular mechanism of SN for treatment of HCC, providing scientific basis for follow-up exploration of the molecular mechanism of SN against HCC.
