ObjectiveThis paper aims to investigate the traditional Chinese medicine syndrome types in patients with chronic hepatitis B （CHB） complicated by metabolic dysfunction-associated fatty liver disease （MAFLD） and explore the correlations between these syndrome types and clinical indicators， as well as ocular manifestation characteristics， thereby providing a reference for syndrome differentiation and treatment strategies in traditional Chinese medicine. MethodsGeneral data， information from the four diagnostic methods of traditional Chinese medicine， clinical indicators， and ocular manifestation data were collected from 506 patients with CHB complicated by MAFLD enrolled at the Public Health Clinical Center of Chengdu between June 2024 and December 2024. Cluster analysis， principal component analysis， and complex network models were employed to identify the distribution patterns of traditional Chinese medicine syndromes. Correlations between different syndrome types and clinical indicators， as well as ocular manifestation characteristics， were further analyzed. ResultsThe predominant syndromes identified in patients with CHB complicated by MAFLD were dampness and heat accumulation （51.58%）， liver depression with spleen deficiency （31.62%）， blood stasis obstructing collaterals （8.89%）， and Qi-Yin deficiency （7.91%）. No statistically significant differences were found among the four syndrome types in routine blood tests and liver function indicators. However， patients with the dampness and heat accumulation type exhibited significantly higher levels of total cholesterol （TC）， triglycerides （TG）， low-density lipoprotein cholesterol （LDL-C）， liver stiffness measurement （LSM）， controlled attenuation parameter （CAP）， and alpha-fetoprotein （AFP）， along with lower levels of high-density lipoprotein cholesterol （HDL-C）， compared with those with other syndrome types. Regarding ocular manifestations， the incidence of moon halo signs was significantly higher in patients with the blood stasis obstructing collaterals type than in those with other syndrome types. Additionally， the incidence in scleral zone 3 （corresponding to the large intestine） was higher in patients with the damp and heat accumulation type. ConclusionDampness and heat accumulation is the core syndrome type in patients with CHB complicated by MAFLD， commonly accompanied by spleen deficiency， liver depression， blood stasis， and Yin deficiency. A complex syndrome pattern characterized by a predominance of dampness and heat， along with a mixture of deficiency and excess， is formed. Different traditional Chinese medicine syndrome types are associated with distinct clinical indicators and ocular manifestation characteristics. Among them， patients with the dampness and heat accumulation type exhibit more pronounced metabolic disturbances and liver injury， whereas those with the blood stasis type show a higher incidence of moon halo signs. Abnormalities in scleral zone 3 are also more prevalent in patients with dampness and heat type.

ObjectiveThis paper aims to investigate the distribution patterns of traditional Chinese medicine syndromes in patients with chronic hepatitis B （CHB） comorbid with metabolically associated fatty liver disease （MAFLD） and analyze their correlation with clinical characteristics and the progression of liver fibrosis. MethodsA cross-sectional study method was employed， and 506 patients with CHB comorbid with MAFLD who attended the Hepatology Outpatient Department of Public Health Clinical Center of Chengdu from June 2024 to December 2024 were enrolled. General information， traditional Chinese medicine syndromes information， laboratory indicators， and imaging examination results were collected using case report forms （CRF）. Tongue images of patients were acquired using a tongue diagnosis instrument， and tongue feature parameters were extracted using computer image processing technology. Frequency analysis， factor analysis， and cluster analysis， and other methods were used to explore syndrome categories and distribution patterns. Non-parametric tests were used to compare the differences in clinical characteristics among different syndromes. Univariate and multivariate logistic regression analyses were performed to investigate the correlation between traditional Chinese medicine syndromes and the progression of liver fibrosis. ResultsThe main traditional Chinese medicine syndromes in patients with CHB comorbid with MAFLD were mainly dominated by damp-heat accumulation syndrome， liver stagnation and spleen deficiency syndrome， and phlegm-blood stasis syndrome， with damp-heat accumulation syndrome accounting for the highest proportion （41.89%）. Compared with those without damp-heat accumulation syndrome， patients with damp-heat accumulation syndrome had significantly lower tongue proper H value， tongue coating H value， and tongue coating a^* value （P<0.05）， significantly higher tongue coating b^* value （P<0.05）， significantly increased levels of white blood cell （WBC）， red blood cell （RBC）， hemoglobin （HGB）， and glucose （GLU）， increased CAP values （P<0.05）， a higher proportion of males （P<0.05）， and a younger age （P<0.05）. Univariate and multivariate logistic regression analyses show that age， hepatitis B surface antigen （HBsAg）， diabetes， and damp-heat accumulation syndrome are independent risk factors for liver fibrosis （P<0.05）， and that damp-heat accumulation syndrome is predominantly distributed in liver fibrosis stage F0-F1. ConclusionDamp-heat accumulation syndrome is a typical syndrome in patients with CHB comorbid with MAFLD， which is significantly associated with enhanced inflammatory response， metabolic disorders， and early liver fibrosis， and is a key link in disease progression. Clinical attention and early intervention are needed.

Radical pelvic surgery is a surgical method mainly used to treat tumors in the pelvic cavity, and erectile dysfunction (ED) is a common sexual dysfunction after surgery. The incidence of ED after radical pelvic surgery is not uniformly understood due to differences in surgical approaches and methods of investigation. The main causes of postoperative ED include intraoperative neurovascular injury, psychosomatic factors and preoperative patient characteristics, with intraoperative injury to the neurovascular bundle being the most common. Studies have shown that the occurrence of postoperative ED can be prevented by active intervention, but still lack of effective treatment measures. This article reviews and summarizes the clinical epidemiological features and research progress in recent years on ED after radical pelvic surgery, and discusses specific measures for the prevention and treatment of postoperative ED.

Objective To compare the effect of nutritional support with and without tube feeding on the incidence of adverse reactions in radiotherapy for esophageal cancer.Methods A total of 120 esophageal cancer patients with high-risk factors receiving radiotherapy were selected and randomly assigned into the tube feeding (TF,n=60) and non-tube feeding groups (NTF,n=60) according to the random number method.Nutritional interventions were performed during radiotherapy in both groups.The incidence of esophagitis and myelosuppressioa,aulmonary infectioa,autritional status and the completion of radiotherapy were observed and statistically compared between TF and NTF groups.Results In the TF groua,ahe incidence of ≥ grade 2 esophagitis was lower than that in the NTF group.The incidence of grade 3 esophagitis significantly differed between two groups (P＜ 0.05).The incidence of grade 1-2 myelosuppression did not differ between two groupa,ahereas the incidence of grade 3 myelosuppression in the TF group was significantly lower than that in the NTF group (P＜0.05).In the TF groua,ahe incidence of pulmonary infection was remarkably lower than that in the NTF group (P＜0.05).The changes of BMI and prealbumin in the TF group were better than those in the NTF group (both P＜0.05).One patient in the NTF group failed to complete the radiotherapy due to grade Ⅳ esophagitia,and 5 cases in the NTF group (P＜ 0.05).In the TF groua,ahe length of hospital stay was significantly shortened by 6.2 d on average (P＜ 0.05).Conclusions During radiotherapy for esophageal cancer patients with high-risk factora,autritional support with tube feeding can effectively reduce the incidence of adverse reactiona,amprove the completion rate of treatmena,and shorten the average length of hospital stay.

Objective To investigate the application value of ultrasound-guided fine-needle aspiration cytology of lymph nodes in the pre-radiotherapy evaluation of superficial lymph nodes metastases in patients with lung cancer and esophageal cancer. Methods A total of 115 patients with lung cancer and esophageal cancer prepared for thoracic radiotherapy from February 2017 to September 2018 in Cancer Hospital of Huanxing Chaoyang District Beijing were retrospectively analyzed. Ultrasound-guided fine-needle aspiration cytology examination was performed in 166 lymph nodes. Puncture tissues were prepared for cytology production. Then cytological specialist read the film to evaluate if the cancer cells metastasis were present after conventional papanicolaou staining. The effects of short diameter of lymph nodes, blood flow signal and tumor characteristics of patients on the results of cytological examination were analyzed. Results The ultrasound results showed the median short diameter of lymph nodes was 0.6 cm (0.2-3.5 cm), and 25 (15.1％) lymph nodes had blood flow signals, 50 (30.1％) lymph nodes had positive results of puncture tissues cytology. The positive rate of puncture tissues cytology was 10.0％(4/40), 21.6％(21/97) and 86.2％(25/29) in the shortdiameter of lymph nodes <0.5 cm group, ≥0.5 cm and <1 cm group, and ≥1 cm group, respectively (P<0.01). Cytology positive rate of lymph nodes with or without blood flow signal detected by ultrasound was 48.0％ (12/25) and 27.0％ (38/141), and there was a statistical difference (P = 0.034). Location of primary tumor, T stage and chemotherapy history had no significant influence on the cytological results in patients with lung cancer (all P> 0.05). Pathological types had a significant influence on cytological results (χ2= 8.050, P= 0.045). Lymph node metastasis of the upper mediastinum was a risk factor for lymph node metastasis in lower neck and supraclavicular region (χ2= 9.699, P= 0.002). Location of primary tumor, T stage and chemotherapy history had no significant influence on cytological results in patients with esophageal cancer (all P> 0.05). Conclusions Ultrasound-guided fine-needle aspiration cytology is safe and efficient. It can be used to evaluate the metastasis status of superficial lymph nodes in pre-radiotherapy patients with lung cancer and esophageal cancer.

OBJECTIVETo explore the effects of electrical stimulation at acupoints in the distribution area of auricular vagus nerve combined with sound masking on auditory brainstem response (ABR) and contents of neurotransmitters of γ-aminobutyric acid (γ-GABA), 5-hydroxytryptamine (5-HT) and acetyl choline (Ach) in inferior colliculus of tinnitus rats.

METHODSTwenty-four male adult SD rats were randomized into a control group, a model group, a 7-d treatment group and a 15-d treatment group. Except the control group, rats in the remaining groups were treated with intraperitoneal injection of 10% salicylate sodium at a dose of 350 mg/kg to establish tinnitus model. Rats in the control group were treated with injection of 0.9% NaCl. Rats in the 7-d treatment group and 15-d treatment group were treated with electrical stimulation at "Shenmen (TF₄)" and "Yidan (CO₁₁)" in the distribution area of auricular vagus nerve combined with sound masking, once a day, for 7 days and 15 days. The SigGenRP software of TDT system was applied to provide voice for single ear and collect the signal, and the voice threshold of ABR was tested. The levels of γ-GABA, 5-HT and Ach in inferior colliculus of rats were detected by enzyme linked immunosorbent assay (ELISA) and compared.

RESULTSCompared with the model group, the threshold values of ABR in 12 kHz and 16 kHz voice stimulation in the 7-d treatment group were significantly lower all P < 0.05); the threshold values of ABR from 4 kHz to 28 kHz voice stimulation in the 15-d treatment group were signally reduced (P < 0.05, P < 0.01), which was more significant than those in the 7-d treatment group. The level of γ-GABA in the model group was significantly lower than that in the control group (P < 0.05), and that in the 15-d treatment group was apparently higher than that in the model group (P < 0.05). The level of 5-HT in the model group was markedly higher than that in the control group (P < 0.05), and that in the 7-d treatment group was lower than that in the model group (P < 0.05), while that in the 15-d treatment group was apparently higher than that in the model group (P < 0.05). The level of Ach in the model group was obviously; lower than that in the control group (P < 0.05), and that in the 7-d treatment group was higher than that in the model group (P < 0.05).

CONCLUSIONElectrical stimulation at auricular vagus nerve combined with sound masking) could regulate the threshold of ABR, especially in the 15-d treatment group. This may be ascribed to modulating the levels of neurotransmitter of γ-GABA, 5-HT and Ach in inferior colliculus.

Objective To explore the rule of traditional Chinese medicine in treating tinnitus based on literature and Logistic multiple regression analysis. Methods Articles about tinnitus treatment using traditional Chinese medicine were searched in several databases, i.e. CNKI (1984-2013), VIP (1989-2013), CBM (1990-2013), and PubMed (1984-2013), and medication frequency was analyzed. Then, models for tinnitus medication were established through metrological method and Logistic multiple regression. Results The common prescriptions with highest frequency usage were Liuwei Dihuang Pill, Longdan Xiegan Decoction, and Erlong Zuoci Pill. Corni Fructus, Psoraleae Fructus, and Lycii Fructus were commonly used for kidney-deficiency type of tinnitus;Astragali Radix, Atractylodis Macrocephalae Rhizoma, and Codonopsis Radix were commonly used for the spleen-qi-deficiency type of tinnitus;Gardeniae Fructus, Gentianae Radix et Rhizoma, and Cyperi Rhizoma were commonly used for the liver-qi-dysfunction type of tinnitus;Pinelliae Rhizoma, Aurantii Fructus Immaturus, and Stephaniae Tetrandrae Radix were commonly used for the phlegm-fire disturbance type of tinnitus;Forsythiae Fructus, Menthae Haplocalycis Herba, and Mori Cortex were commonly used for the wind-fire-invasion type of tinnitus. Conclusion Analysis of medication frequency and Logistic multiple regression analysis can provide evidence and reference for the treatment of tinnitus and syndrome differentiation.

Objective To analyze the occurrence of clinical adverse drug reaction (ADR) of tonic Chinese medicinal herbs. Methods Articles about ADR of tonic Chinese medicinal herbs reported from January 1990 to February 2014 were collected from databases of CNKI, VIP, CBM, Pubmed and Embase according to incorporation and exclusion standard. Metrology analysis was also conducted. Results Totally 378 effective articles showed tonic Chinese medicinal herbs most likely to induce ADR were as follows:individual Chinese medicinal herbs including Polygoni Multiflori Radix, Ginseng Radix et Rhizoma, Lycii Fructus and Astragali Radix;injection containing Shenmai Injection, Shengmai Injection and Acanthopanax Injection;other herbal preparation covering Polygoni Multiflori tablets. The most common ADR involved the damage on skin tissue, nervous system and digestive system, with prominent relevant clinical symptoms such as itching, skin rash, dizziness, unconsciousness, nausea, vomiting, and liver dysfunction. Conclusion Correct understanding adverse reaction of tonic Chinese medicinal herbs will be conducive to rational drug use and avoiding risk.
