Guided by the theories of yin-yang and collateral disease， this paper identifies the dysregulation of yang qi ascent and descent as the core pathomechanism of hypertension. Based on clinical experience， a treatment approach centered on the method of raising yang and promoting descent was proposed. Clinically， three major syndrome types were identified. Firstly， deficiency of zong qi （ancestral qi） with blood stasis， obstruction of phlegm-turbidity and blood stasis， and hyperactivity of liver yang. Corresponding empirical formulation， Yizong Huoxue Decoction （益宗活血汤） was applied to tonify zong qi， invigorate blood， and raise yang. Secondly， Lizong Huoxue Decoction （理宗活血汤） was used to resolve phlegm， promote yang qi circulation， and regulate qi and blood. Thirdly， Qinggan Tongluo Decoction （清肝通络饮） was used to clear the liver， dredge collaterals， and subdue hyperactive yang. For special types such as non-dipper hypertension， time-specific syndrome differentiation and treatment can be applied based on a thorough understanding of the underlying pathomechanism， aiming to provide new insights into clinical diagnosis and treatment of hypertension.

Objective:To investigate the influencing factors for microvascular invasion (MVI) in hepatocellular carcinoma based on three-dimensional visualization and the construction of its nomogram model.Methods:The retrospective cohort study method was conducted. The clinico-pathological data of 190 patients with hepatocellular carcinoma who were admitted to Henan University People′s Hospital from May 2018 to May 2021 were collected. There were 148 males and 42 females, aged (58±12)years. The 190 patients were randomly divided into the training set of 133 cases and the validation set of 57 cases by the method of random number table in the ratio of 7:3. The abdominal three-dimensional visualization system was used to characterize the tumor morphology and other imaging features. Observation indicators: (1) analysis of influencing factors for MVI in hepatocellular carcinoma; (2) construction and evaluation of nomogram model of MVI in hepatocellular carcinoma. Measurement data with normal distribution were expressed as Mean± SD, and independent sample t test was used for comparison between groups. Measurement data with skewed distribution were expressed as M( Q1, Q3), and non-parametric rank sum test was used for comparison between groups. Count data were expressed as absolute numbers, and the chi-square test was used for comparison between groups. Corresponding statistical methods were used for univariate analysis. Binary Logistic regression model was used for multivariate analysis. Receiver operator characteristic (ROC) curves were plotted, and the nomogram model was assessed by area under the curve (AUC), calibration curve, and decision curve. Results:(1) Analysis of influencing factors for MVI in hepatocellular carcinoma. Among 190 patients with hepatocellular carcinoma, there were 97 cases of positive MVI (including 63 cases in the training set and 34 cases in the validation set) and 93 cases of negative MVI (including 70 cases in the training set and 23 cases in the validation set). Results of multivariate analysis showed that alpha-fetoprotein, vascular endothelial growth factor, tumor volume, the number of tumors, and tumor morphology were independent factors affecting the MVI of patients with hepatocellular carcinoma ( odds ratio=5.06, 3.62, 1.00, 2.02, 2.59, 95% confidence interval as 1.61-15.90, 1.28-10.20, 1.00-1.01, 1.02-3.98, 1.03-6.52, P<0.05). (2) Construction and evaluation of nomogram model of MVI in hepatocellular carcinoma. The results of multivariate analysis were incorporated to construct a nomogram prediction model for MVI of hepatocellular carcinoma. ROC curves showed that the AUC of the training set of nomogram model was 0.85 (95% confidence interval as 0.79-0.92), the optimal fractional cutoff based on the Jordon′s index was 0.51, the sensitivity was 0.71, and the specificity was 0.84. The above indicators of validation set were 0.92 (95% confidence interval as 0.85-0.99), 0.50, 0.90, and 0.82, respectively. The higher total score of the training set suggested a higher risk of MVI in hepatocellular carcinoma. The calibration curves of both training and validation sets of nomogram model fitted well with the standard curves and have a high degree of calibration. The decision curve showed a high net gain of nomogram model. Conclusions:Alpha-fetoprotein, vascular endothelial growth factor, tumor volume, the number of tumors, and tumor morphology are independent influencing factors for MVI in patients with hepatocellular carcinoma. A nomogram model constructed based on three-dimensional visualized imaging features can predict MVI in hepatocellular carcinoma.

Objective·To measure the parameters of the uterine artery,umbilical artery and middle cerebral artery in a rat model of preeclampsia(PE)by Doppler ultrasound,and compare the pathological changes in placental blood vessels and pregnancy outcomes,in order to provide an effective method and reference for evaluating placental function in PE animal models.Methods·PE(n=8)and normal pregnancy(NP,n=8)groups in Sprague-Dawley(SD)rat models were established by intraperitoneal injections of N'-nitro-L-arginine methylesterhydrochloride(L-NAME)and 0.9%sodium chloride solution.Blood pressure and proteinuria indexes were detected to evaluate whether the model was successfully established.On gestational day 19(GD19),Doppler ultrasound was utilized to measure the parameters of the uterine artery,umbilical artery and the fetal middle cerebral artery in both the PE and NP groups.After termination of the pregnancies,placental function was evaluated through the pathology of placental blood vessels and the quality of the fetuses and placentas.Results·In the PE group,both blood pressure(GD15:P=0.001;GD19:P=0.001)and proteinuria(GD15:P=0.001;GD19:P=0.001)were significantly higher than those in the NP group.The pulsatility index(PI)of the umbilical artery and uterine artery was notably elevated in the PE group compared to the NP group(both P=0.000).Furthermore,the resistance index(RI)of the fetal middle cerebral artery was significantly lower than that in the PE group(P=0.000).While the number of fetal rats did not differ significantly,the quality of placental and fetal rats was notably lower in the PE group(P=0.006 and P=0.000,respectively).Immunohistochemical staining of placental tissue revealed that the number of placental micro vessel densities in the PE group was less than that in the NP group(P=0.001).Correlation analysis revealed that placental micro vessel density,fetal quality and placental quality were inversely related with the RI of the umbilical artery and the PI and RI of the uterine artery,and positively correlated with the S/D,PI and RI of the fetal middle cerebral artery(all P<0.05).Conculsion·Doppler ultrasound assessment of the uterine artery,umbilical artery and middle cerebral artery indices in L-NAME-induced PE rat models effectively reflects pregnancy outcomes and placental vascular pathology.This method is valuable for evaluating placental vascular perfusion in PE rat models,offering practicality and convenience for research involving animal models.

Objective:To explore the nutritional status and quality of life of gastric cancer patients one month after operation in the context of enhanced recovery, and analyze the correlation between them.Methods:From August 2020 to August 2021, 168 patients discharged from the Gastrointestinal Surgery of Ningbo First Hospital after radical resection of gastric cancer were selected as the study subject by convenience sampling. The Nutritional Risking Screening 2002 (NRS2002) and the Global Leadership Initiative on Malnutrition (GLIM) step 2 (excluding muscle mass measurement index) were used to assess the postoperative nutritional status of patients. The quality of life of patients with gastric cancer after operation was investigated with the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30) . Logistic regression analysis was used to explore the influencing factors of nutritional status of postoperative patients with gastric cancer. A total of 168 questionnaires were distributed, and 168 valid questionnaires were recovered, with a valid recovery rate of 100.0%.Results:A total of 104 patients (61.9%) had nutritional risk and 46 patients (27.4%) had malnutrition. There were statistical differences in age, education level, tumor stage, body mass index, physical function, role function, emotional function, cognitive function, general health, fatigue, nausea and vomiting, and loss of appetite among gastric cancer patients with different nutritional status after operation ( P<0.05) . Logistic regression analysis showed that body mass index, physical function, role function, emotional function and fatigue were the influencing factors of the nutritional status of patients one month after operation ( P<0.05) . Conclusions:In the context of enhanced recovery, the nutritional risk and malnutrition rate of gastric cancer patients one month after operation are high, and are closely related to the quality of life. When implementing enhanced recovery after surgery, medical and nursing staff should strengthen and optimize the nutrition management of gastric cancer patients before hospital, during perioperative period and after discharge, improve the nutritional status after operation and the quality of life of patients.

Objective:To construct a cluster care of oral nutrition supplements (ONS) , and to explore its effect in home care of postoperative patients with gastric cancer.Methods:Literature search was conducted to review the status quo of ONS compliance at home in patients with gastric cancer after surgery, and analyze the existing problems. We summarized and formulated the cluster care plan according to the evidence, and established the home ONS management team and process. From November 2020 to October 2021, 107 patients with gastric cancer who needed to implement ONS at home in Gastrointestinal Surgery of Ningbo First Hospital were selected as research objects by convenience sampling. Postoperative patients with gastric cancer from November 2020 to April 2021 were set as the control group ( n=40) , and those from May to October 2021 were set as the observation group ( n=67) . The control group was treated with conventional ONS, and the observation group was treated with home ONS cluster care plan on the basis of the control group. The compliance of nutritional support, weight gain, body mass index increase and follow-up experience between the two groups were evaluated. Results:After six months of intervention, the scores of ONS compliance, weight gain, body mass index increase and follow-up experience in the observation group were significantly higher than those in the control group, and the differences were statistically significant ( P<0.05) . Conclusions:The cluster care plan improves the ONS compliance at home, nutritional status and satisfaction with the follow-up by medical and nursing staff in patients with gastric cancer after surgery, which is worthy of clinical promotion.

Objective: To summarize the clinical manifestations of IgG4-related diseases in the head and neck, explore treatment methods. Methods : The clinical data of 21 patients diagnosed with IgG4-related diseases were retrospectively analyzed. The clinical data and the results of glucocorticoid and immunosuppressive therapy were studied retrospectively. Results: All patients had swollen sclerotic masses, and CT showed irregular high-density masses with uniform enhancement in the enlarged glands. Some patients had mucosal thickening and mass-like changes in theoral cavity, nose, sinuses, throat and other tissues, and most of the patients had cervical lymphadenopathy and elevated serum IgG4 levels (≥ 1.35 g/L). Histopathological examination of affected exosine glands and affected mucosa and lymph nodes in all patients showed infiltration of lymphocytes, plasma cells and IgG4+ plasma cells. In 21 patients, the mass in the affected glands and mucosa (including head, neck and other tissues) disappeared, and the clinical symptoms were relieved after the application of glucocorticoids. However, with a reduction in glucocorticoids, the mass recurred or even worsened. Conclusion For patients with a single mass in the submandibular gland, parotid gland and other salivary glands, as well as lymph node enlargement, CT is the first choice to identify the nature of gland neoplasms. Combined with pathological examination, related auxiliary examination and peripheral blood examination are also needed to obtain a definitive diagnosis. Glucocorticoid therapy is used to achieve a good prognosis, and long-term follow-up and timely adjustment of medication regimens are required.

Objective:To investigate the effect of sarcopenia on physical performance and nutritional status in elderly patients with gastrointestinal tumors.Methods:a total of 120 eligible in-patients were enrolled from gastrointestinal surgery department of a Grade A tertiary hospital in Ningbo city from September 2021 to January 2022. General clinical data were collected, nutritional risk was screened using Nutritional Risk Screening 2002 (NRS 2002), physical performance was assessed by Short Physical Performance Battery (SPPB), skeletal muscle index at the third lumbar vertebra level (L3 SMI) was calculated using abdominal CT scan, and grip strength/muscle strength, gait speed by 6 Meter Timed Walk Test and calf circumference were measured. Subjects were divided into sarcopenia and non-sarcopenia group according to the diagnostic criteria of the Asian Working Group for Sarcopenia (AWGS). Impacting factors of sarcopenia and the correlation between muscle mass and physical performance in elderly patients with gastrointestinal tumors were analyzed.Results:The overall prevalence rate of sarcopenia in elderly patients with gastrointestinal tumors was 28.3% (34/120) and it was 28.9% (22/76) and 27.3% (12/44) in males and females respectively. There were statistically significant differences in age, tumor stage, nutritional risk, body mass index, calf circumference, L3 SMI, grip strength/muscle strength, gait speed and SPPB score between patients with and without sarcopenia (P<0.05). Muscle strength/grip strength, L3 SMI and gait speed were closely correlated with the occurrence of sarcopenia in elderly patients with gastrointestinal tumors (P<0.05). The L3 SMI was positively correlated with physical performance as assessed with SPPB in both groups.Conclusions:Sarcopenia is a common complication in elderly patients with gastrointestinal tumors with multiple influencing factors. Timely nutritional intervention and exercise intervention should be incorporated into the treatment of elderly gastrointestinal tumor patients with sarcopenia in order to improve nutrition status.

Objective:To retrieve relevant evidence for early enteral nutrition support in patients after gastric cancer surgery and summarize the best evidence, so as to provide evidence-based evidence for clinical implementation of postoperative enteral nutrition management for gastric cancer.Methods:Evidence-based questions were established according to PIPOST principles, UpToDate, Cochrane Library, Joanna Briggs Institute Library, BMJ Best Practice, Agency for Healthcare Research and Quality website, Medlive, European Society for Clinical Nutrition and Metabolism website, American Society for Parenteral and Enteral Nutrition website, Embase, Medline, PubMed, SinoMed, Wanfang Database, China National Knowledge Infrastructure were searched according to the "6S" evidence model. The retrieval period of every database was from January 1, 2016 to May 31, 2021. The Evidence Pre-Grading and Evidence Recommendation Grading System (2014) of Australian Joanna Briggs Institute Evidence-Based Health Care Center was used to extract evidence from the literature that met the quality standards, determine the evidence grading and recommendation level and form the best evidence.Results:A total of 317 literatures were retrieved, and 10 literatures were included, including 1 guideline, 4 expert consensus and 5 systematic reviews. The 10 evidences were summarized from 4 aspects, including indication evaluation, timing management, route and preparation management and risk management.Conclusions:Current evidence shows that early enteral nutrition is safe and feasible in patients after gastric cancer surgery. In the process of implementing enteral nutrition, medical staff should fully evaluate the indications and needs of patients and make clear and prudent choices for nutritional support channels and preparations of patients, so as to form the best evidence and clinical management programs for early enteral nutrition support for patients after gastric cancer surgery and accelerate postoperative recovery of patients.

Objective:To investigate the relationship between discharge readiness and nutritional status of patients undergoing gastric cancer surgery in the context of enhanced recovery after surgery (ERAS) , so as to provide individualized guidance for patients after discharge.Methods:Using the convenient sampling method, a total of 120 patients who underwent radical gastrectomy for gastric cancer from June 2020 to June 2021 in Ningbo First Hospital were selected as research objects, and they all received ERAS nursing care. One day before discharge, Nutritional Risk Screening Table and Discharge Readiness Scale were used for questionnaire analysis.Results:The total score of discharge readiness of 120 patients with gastric cancer after surgery was (81.42±6.87) . Among the three dimensions, personal status was (19.65±2.19) , adaptability was (29.67±3.10) and anticipatory support was (32.10±2.61) . 57.5% (69/120) of gastric cancer patients discharged from hospital had nutritional risk. The scores of hospital discharge readiness and the scores of each dimension in the nutritional risk group were lower than those in the non-nutritional risk group, and the differences were statistically significant ( P<0.05) . Multivariate analysis showed that nutritional status was an influencing factor for the total score of hospital discharge readiness in patients with gastric cancer surgery (standardized regression coefficient was 0.321, P<0.05) . Conclusions:Under the background of ERAS, the discharge readiness of patients after gastric cancer surgery is at a moderate level, postoperative patients are generally at nutritional risk and the discharge readiness of patients with nutritional risk is lower than that of patients without nutritional risk. Perioperative nutrition management by nursing staff can improve the discharge readiness of patients undergoing gastric cancer surgery, and continuous nutrition management should be carried out for discharged patients with nutritional risk, in order to promote home rehabilitation of patients with gastric cancer surgery.

Objective: To examine the outcome of surgical treatment in patients with stages Ⅱ-Ⅲ bisphosphonate-related osteonecrosis of the jaw. Methods: Twenty-nine patients with bisphosphonate-related osteonecrosis of the jaw were examined. The patients were followed up for more than 6 months, and the treatment outcome was reviewed. Results: After curettage of local lesions, 19 out of the 21 patients were cured, and 2 were relieved of symptoms. Six patients underwent subtotal resection of the maxilla, and the symptoms disappeared completely after the surgery. Two patients underwent partial resection of the mandible and recovered. Conclusion Surgical debridement is an effective measure for the treatment of patients with bisphosphonate-related osteonecrosis of the jaw in stages Ⅱ-Ⅲ. In most cases, curettage of local lesions via the intraoral approach can completely remove sequestrum and inflammatory granulomatous tissue. Subtotal maxillary resection or partial mandible resection is performed when the bone death reaches the level of the maxillary sinus floor or continues to the mandible. By timely surgical intervention, the bone lesion is removed to maintain the sterile, active bone microenvironment locally.
