This paper summarizes Professor Gao Jiansheng's clinical experience in treating herpes simplex keratitis （HSK） based on the theory of hidden pathogens. It is believed that the core pathogenesis of HSK involves deficiency of vital qi and the internal presence of pathogenic factors. In the early stage， the pathogenesis is characterized by lung and spleen qi deficiency and invasion of external pathogens. In the middle stage， pathogenesis worsens due to latent pathogens damaging the vital qi and spleen deficiency with dampness. In the late stage， kidney yang deficiency and lingering pathogenic toxins are the root cause of recurrent attacks. In clinical practice， it is recommended to strengthen and protect the vital qi. In the early stage， the Modified Yupingfeng Powder （玉屏风散） is used. In the middle stage， the Modified Linggui Zhugan Decoction （苓桂术甘汤） is used. In the late stage， a self-formulated Modified Bushen Tuodu Fomulation （补肾托毒方） is applied. Additionally， herbs of tonifying qi and strengthening the exterior are used throughout the treatment to reduce recurrence.

Background Pneumoconiosis is a chronic inflammatory disease that cannot be completely cured. Therefore, how to control lung inflammation and delay of the body aging is one of the keys to treating pneumoconiosis. The studies in past two decades suggested that many small molecule drugs are able to enhance cardiopulmonary function. Objective To explore the effects of homeopathic dosing and combined dosing of β-nicotinamide mononucleotide and taurine on experimental silicosis in rats. Methods Seventy-two SD specific pathogen-free rats were randomized into 4 groups (18 mice in each group): negative control group (ultrapure water, without dust), positive control group, homeopathic treatment group, co-administered treatment group. One mL of quartz dust suspension was injected into the rat trachea by disposable non-exposed tracheal injection method (50 mg·mL⁻¹) to establish a rat silicosis model. Rats were administered by gavage since the 4th day after dust exposure. The homeopathic treatment group rats received taurine solution (0.03 g·mL⁻¹) in the morning and β-nicotinamide mononucleotide (0.03 g·mL⁻¹) in the afternoon; the co-administered treatment group rats received a mixed solution (0.015 g·mL⁻¹ β-nicotinamide mononucleotide + 0.015 g·mL⁻¹ taurine) twice, in the morning and afternoon respectively. The positive and negative control groups received equivalent of ultrapure water in the morning and afternoon. All groups of rats were administered 5 d a week for a total of 6 weeks. The rats were neutralized after 6 weeks of administration. Organ coefficient, lung hydroxyproline content, whole lung dry and wet weights, whole lung free silica content, and cell count and classification in lung lavage fluid were measured and calculated, and lung histopathological changes in lung samples were observed. Results Compared with the positive control group, the whole lung wet weight, whole lung dry weight , total cell count, neutrophil rate, lung organ coefficient, lung hydroxyproline content, and whole lung free silica content were reduce in the homeopathic treatment group, and the co-administered treatment group (P＜0.05). Compared with the negative control group, the total cell count, neutrophil rate, lung organ coefficient, lung hydroxyproline content, and whole lung free silica content were elevated in the homeopathic treatment group and the co-administered treatment group, the whole lung dry weight was elevated in the co-administered treatment group, and those differences were all statistically significant (P＜0.05). The rat lung histopathological results showed that, in the positive control group, round or oval nodules were formed in the lung tissue, which were phagocytic cellular nodules, and the alveolar structures in some areas still existed. The histopathological changes in the homeopathic treatment group and the co-administered treatment group were similar to those of the positive group, but less severe. No pathological change was observed in the lung tissue of the negative control group. Conclusion Some improvement and dust removal in experimental silicosis rats by homeopathic dosing and combined dosing of β-nicotinamide mononucleotide and taurine are observed.

Benign essential blepharospasm(BEB)is a neurological disorder characterized by involuntary contractions of periocular muscles, which can lead to functional blindness and significantly impair patients' quality of life. This article systematically reviews the epidemiology, clinical manifestations, pathogenesis, and therapeutic advances in BEB. Epidemiological data indicate that the global prevalence of BEB is approximately 1 in 200000, with a predilection for individuals over 50 years of age and a significantly higher incidence in female than in male. The exact pathogenesis of BEB remains incompletely understood, though current evidence suggests close associations with neurotransmitter dysfunction, reduced cortical inhibition, and genetic susceptibility. Therapeutic strategies primarily focus on symptomatic management. Botulinum toxin type A(BTX-A)injection remains the first-line treatment but requires repeated administrations due to transient efficacy. Other treatments, including oral drugs, surgery, and repetitive transcranial magnetic stimulation, also have major limitations. By synthesizing recent research progress from domestic and international studies, this review aims to provide novel insights for the clinical management of BEB, ultimately improving patient outcomes.

Objective:To investigate the association of time in range with metabolic associated fatty liver disease(MAFLD) and advanced liver fibrosis in patients with type 2 diabetes.Methods:This study was a retrospective study. A total of 494 type 2 diabetic patients were recruited in the Department of Endocrinololgy of Henan Provincial People′s Hospital from November 2019 to April 2022. Time in range(TIR) was calculated with continuous glucose monitoring data. Abdominal ultrasound scan was used to diagnose fatty liver. Liver stiffness measurement(LSM) by transient elastography was used to evaluate liver fibrosis. Pearson and multivariate linear regression analysis was used to evaluate the association between TIR and LSM. Multivariate logistic regression analysis was used to analyze the association of TIR with risk of MAFLD and advanced liver fibrosis.Results:Pearson correlation analysis showed that LSM was negatively correlated with TIR( r=-0.86, P<0.001) and was positively correlated with homeostasis model assessment for insulin resistance(HOMA-IR; r=0.48, P<0.001). After adjusting for confounding factors, multivariate linear regression analysis showed that TIR significantly negatively predicted LSM( β=-0.75, P<0.001), and HOMA-IR significantly positively predicted LSM( β=0.21, P=0.025). After adjusting for confounding factors, logistic regression analysis showed that compared with TIR Q4 patients, TIR Q1 patients had an increased risk of MAFLD( OR=1.96, 95% CI 1.07-3.62, P=0.027), advanced liver fibrosis( OR=3.82, 95% CI 1.17-12.50, P=0.027), and HOMA-IR was an independent risk factor for MAFLD( OR=1.22, 95% CI 1.04-1.43, P=0.005) and advanced liver fibrosis( OR=1.26, 95% CI 1.03-1.54, P=0.025). Conclusions:TIR and insulin resistance are independent risk factors for MAFLD and advanced liver fibrosis in patients with type 2 diabetes. TIR has a significant predictive value for MAFLD and advanced liver fibrosis.

Objective:To retrospectively analyze the treatment status of tyrosine kinase inhibitors (TKI) in newly diagnosed patients with chronic myeloid leukemia (CML) in China.Methods:Data of chronic phase (CP) and accelerated phase (AP) CML patients diagnosed from January 2006 to December 2022 from 77 centers, ≥18 years old, and receiving initial imatinib, nilotinib, dasatinib or flumatinib-therapy within 6 months after diagnosis in China with complete data were retrospectively interrogated. The choice of initial TKI, current TKI medications, treatment switch and reasons, treatment responses and outcomes as well as the variables associated with them were analyzed.Results:6 893 patients in CP ( n=6 453, 93.6%) or AP ( n=440, 6.4%) receiving initial imatinib ( n=4 906, 71.2%), nilotinib ( n=1 157, 16.8%), dasatinib ( n=298, 4.3%) or flumatinib ( n=532, 7.2%) -therapy. With the median follow-up of 43 ( IQR 22-75) months, 1 581 (22.9%) patients switched TKI due to resistance ( n=1 055, 15.3%), intolerance ( n=248, 3.6%), pursuit of better efficacy ( n=168, 2.4%), economic or other reasons ( n=110, 1.6%). The frequency of switching TKI in AP patients was significantly-higher than that in CP patients (44.1% vs 21.5%, P<0.001), and more AP patients switched TKI due to resistance than CP patients (75.3% vs 66.1%, P=0.011). Multi-variable analyses showed that male, lower HGB concentration and ELTS intermediate/high-risk cohort were associated with lower cytogenetic and molecular responses rate and poor outcomes in CP patients; higher WBC count and initial the second-generation TKI treatment, the higher response rates; Ph + ACA at diagnosis, poor PFS. However, Sokal intermediate/high-risk cohort was only significantly-associated with lower CCyR and MMR rates and the poor PFS. Lower HGB concentration and larger spleen size were significantly-associated with the lower cytogenetic and molecular response rates in AP patients; initial the second-generation TKI treatment, the higher treatment response rates; lower PLT count, higher blasts and Ph + ACA, poorer TFS; Ph + ACA, poorer OS. Conclusion:At present, the vast majority of newly-diagnosed CML-CP or AP patients could benefit from TKI treatment in the long term with the good treatment responses and survival outcomes.

BACKGROUND: In recent years, the development of tissue engineering has provided a new approach for the treatment of periodontal bone defect. Tissue engineering therapy includes seed cells, scaffolds and growth factors. Platelet gel contains a large number of platelet growth factors, and collagen is often used for the preparation of scaffold materials. Therefore, the platelet gel and collagen biologically active composite membrane can provide scaffolds and growth factors for the defect bone. OBJECTIVE: To investigate the effect of autologous platelet gel-collagen biologically active composite membrane on the repair of periodontal bone defect in rats. METHODS: Forty-two Wistar rats (Shanghai Xipuer-Bikai Experimental Animal Co., Ltd., China) were selected. (1) Collagen was cut into 5 mm×2 mm size, and 10 mL of whole blood was extracted from 6 rats to obtain platelet-rich plasma. Autologous platelet gel-collagen composite membrane was prepared by adding bovine thrombin, calcium chloride and collagen in a certain proportion. Platelets in whole blood and in platelet-rich plasma were detected. The levels of platelet derived growth factor AB, transforming growth factor-β, basic fibroblast growth factor and vascular endothelial growth factor in whole blood and platelet-rich plasma were detected by ELISA. (2) The models of mandibular periosteal defect were established in 36 rats (the size of the bone defect was 5 mm×2 mm, and the root surface cementum was removed) , and randomly divided into two groups. Autologous platelet gel-collagen group placed the autologous platelet gel-collagen composite membrane in the bone defect, and the control group did not place any materials. The hematoxylin-eosin staining of periodontal tissues of rats in each group was analyzed at 2, 4 and 8 weeks after surgery. Rate of new born, new centumum formation, new alveolar bone formation, and new periodontal ligament tissue formation height were measured. The expression of bone morphogenetic protein-2 was detected by immunohistochemical staining. RESULTS AND CONCLUSION: (1) The mean platelet count in platelet-rich plasma was 4.78 times as high as the whole blood, indicating that the number of platelets increased significantly after prepared into platelet-rich plasma (P < 0.05) . The levels of platelet derived growth factor AB, transforming growth factor-β, basic fibroblast growth factor and vascular endothelial growth factor in platelet-rich plasma were 3.10, 3.45, 7.17 and 5.45 times of the whole blood, respectively (P < 0.05) . (2) The results of hematoxylin-eosin staining observed that the rate of new born, new centumum formation, new alveolar bone formation, and new periodontal ligament tissue formation height at 2 weeks in the autologous platelet gel-collagen group showed no significant difference from the control group (P> 0.05) . At 4 and 8 weeks, all above indexes in the autologous platelet gel-collagen group were significantly higher than those in the control group (P < 0.05) . (3) Results of immunohistochemical staining revealed that at 2 weeks, bone morphogenetic protein-2 in the autologous platelet gel-collagen group began to express, and the expression of bone morphogenetic protein-2 was highest at 4 weeks (P < 0.05) , and the positive expression was weakened at 8 weeks (P> 0.05) . (4) Our results clarify that autologous platelet gel-collagen bioactive composite membrane can significantly promote the regeneration of new tooth, which is associated with the expression of bone morphogenetic protein-2, and reduce the repair time after periodontal tissue defect.

OBJECTIVE:To prepare the norcantharidin (NCTD) nano-micelle and study its antitumor effect. METHODS:NCTD nano-micelle was self-formed in water using Triblock copolymers distearyl phosphatidylethanolamine-polyethylene glycol-ma-leimide;its shape was observed,the drug-loading rate,entrapment efficiency,particle size,Zeta potential were investigated. MTT was used to investigate the cell survival rate of human lung cancer A549 cells in negative control group (Phosphate buffer solu-tion),carrier group (blank nano-micelle),positive control group (NCTD APIs,5-320 μg/mL) and NCTD nano-micelle group (NCTD,5-320 μg/mL) after acting different time (24,48,72 h). Tumor nude mice were randomly divided into blank control group,NCTD injection group(1 mg/kg),NCTD low-dose,high-dose groups(0.5,1 mg/kg),6 in each group. All mice were in-travenously injected relevant medicines in tail,once a day,for 8 weeks. Tumor size was measured every week,and tumor quality was detected after the second day of finishing administration. RESULTS:NCTD nano-micelle was round,drug-loading rate was (2.82±0.05)%,entrapment efficiency was(83.67±1.78)%,particle size was(138.6±45.8)nm,Zeta potential was -(12.75± 0.34)mV(n=6). Cell survival rate of A549 cells in carrier group had no obvious changes,and was obviously decreased in posi-tive control group and NCTD nano-micelle group,which was positively correlated with concentration and time. And the decrease degree of cell survival rate in NCTD nano-micelle group was stronger than positive control group(P<0.01). Compared with blank control group,the tumor quality of mice in 3 administration groups was reduced (P<0.05),the reduction degree in NCTD na-no-micelle high-dose group was stronger than NCTD nano-micelle injection group (P<0.05). CONCLUSIONS:NCTD nano-mi-celle is successfully prepared,which has good in vitro and in vitro anti-tumor effect on A549 cells.
