Chaihu Guizhi Ganjiangtang （CGG）is a classic prescription in the Treatise on Cold Damage，which has the effects of clearing and relieving stagnation heat in Shaoyang，warming and dissolving water drink，and relieving the pivot mechanism. It is a classic prescription for treating spleen deficiency and liver depression and stopping internal stagnation caused by water drink. The formula is exquisite and well-matched and is often modified and used by ancient and modern medical practitioners to treat various miscellaneous diseases of internal and external medicine，with significant therapeutic effects. In recent years，with the rapid development of modern pharmacology，research on the micro mechanism of CGG has been continuously developed and deepened，providing new ideas for the treatment of diseases with CGG. Therefore，the authors systematically searched databases such as China National Knowledge Infrastructure，Wanfang Data Knowledge Service Platform，VIP Database， and PubMed for literature on the clinical application and pharmacological mechanism of CGG published by Chinese and foreign scholars in recent years. This article summarized the literature from two aspects：the modern clinical application and mechanism of action of CGG and elaborated on the diseases treated by CGG in modern literature，involving digestive system，respiratory system，nervous system，endocrine system，circulatory system，urinary system，gynecology，as well as its application in reducing the side effects of radiotherapy and chemotherapy， gynecology， dermatology， ophthalmology， and orthopedics. At the same time，the mechanism of CGG in treating diseases may be related to anti-inflammatory，anti-oxidative stress， regulation of immunity， anti-fibrosis， anti-tumor， improvement of gastrointestinal flora and motility， protection of liver tissue， reduction of blood lipids and blood sugar， and regulation of hormone levels.

Objective:To evaluate the effect of ultrasound-guided subserratus anterior plane block on postoperative analgesia in patients un-dergoing laparoscopic radical gastrectomy.Methods:Sixty patients who underwent elective laparoscopic radical gastrectomy were enrolled between May 2022 and October 2023 at Tianjin Medical University Cancer Institute&Hospital.Patients were assigned into two groups us-ing a random number table method:the control(group C)and the ultrasound-guided serratus anterior plane block(SAPB)(group S).Patient-controlled intravenous analgesia(PCIA)was administered at the end of the surgery.After surgery,visual analogue scale(VAS)of static pain scores was evaluated at 1,6,12,24,and 48 hours.PCIA pump was started at the VAS pain score≥4 after surgery,and sufentanil 0.1μg/kg was intravenously injected when the efficacy was inadequate.The requirement for PCIA use,time to first postoperative anal exhaust,first postoperative out-of-bed activity,first oral intake,and the duration of hospitalization stay were recorded for the two groups.Results:VAS scores were significantly lower at postoperative 1,6,and 12 h in group S than in group C(P<0.05).Additionally,the number of effective uses of PCIA,and rescue analgesia were significantly lower in group S[(6.1±0.4)(2)]than in group C[(18.6±1.4)(17)](P<0.001).The time to first postoperative anal exhaust,first postoperative out-of-bed activity,first oral intake,and duration of hospital stay were shortened in group S than in group C(P<0.05).There were no significant differences in other parameters between these two groups.Conclusion:Ultrasound-guided SAPB can reduce postoperative pain and facilitate fast recovery in laparoscopic radical gastrectomy patients.

Objective:To evaluate the effect of ultrasound-guided internal branch of superior laryngeal nerve(ibSLN) block on the quality of anesthesia recovery in the patients undergoing intracranial tumor surgery.Methods:The data from patients of either gender, aged 18-65 yr, with a body mass index of 18-28 kg/m 2, who underwent intracranial tumor surgery from December 2022 to October 2023, were retrospectively collected. Patients were divided into control group (group C) and ultrasound-guided ibSLN block group (group U). Bilateral ibSLN block was performed with 0.375% ropivacaine hydrochloride 2 ml.The tracheal extubation time, emergence time, development of cardiovascular events within 15 min after extubation, emergence agitation, Ramsay sedation score, Steward recovery score, visual analogue scale scores at 10 min after extubation and development of postoperative sore throat and hoarseness in postanesthesia care unit were recorded. Results:Compared with group C, the incidence of emergence agitation, Ramsay sedation score, visual analogue scale scores and sore throat were significantly decreased, the incidence of hoarseness was increased ( P<0.05), and no significant change was found in the extubation time, emergence time and Steward recovery score in group U( P>0.05). No hypertension, hypotension, tachachycardia and bradycardia were found in two groups. Conclusions:Ultrasound-guided ibSLN block can improve the quality of anesthesia recovery in the patients undergoing intracranial tumor surgery.

Objective To explore the relevant protective/risk factors during the development of coronary heart disease blood stasis evidence in the process of pre-existing evidence based on the macro-,meso-,and micro-health state characterization parameter system of Chinese medicine state science.Methods 253 cases of coronary heart disease to be investigated were collected from the outpatient and inpatient departments of the Department of Cardiology in the hospitals affiliated to Hunan University of Traditional Chinese Medicine,and questionnaires were formulated according to the three dimensions of macro,meso,and micro,and the collected parameters were categorized with Python software,and the patients were diagnosed as pre-coronary heart disease blood stasis evidence(150 cases)and coronary heart disease blood stasis evidence(100 cases),and statistical analyses were performed with frequency analysis,χ2 test,and Logistic regression and other methods for statistical analysis.Results ①The results of univariate analysis showed that:age,BMI,history of smoking,history of alcohol consumption,history of hypertension,history of diabetes mellitus,average monthly high temperature,air quality,season,type of occupation,social environment,coronary artery angiographic stenosis,diastolic blood pressure,systolic blood pressure,creatinine,uric acid and total cholesterol differed between patients diagnosed as pre-Coronary artery disease blood stasis evidence and those diagnosed as Coronary artery disease blood stasis evidence,and all the differences were statistically significant(P<0.05).② Binary logistic regression analysis showed that age,BMI,history of alcohol consumption,type of occupation,coronary angiographic stenosis,diastolic blood pressure,creatinine,and dark red tongue were independent risk factors.A prediction model was established:P=1/[1+exp(16.522-1.427×age-0.975×BMI-3.55×drinking history+1.982×monthly average high temperature+0.709×season-1.827×occupational type-1.1×coronary angiographic stenosis-0.072×diastolic blood pressure-0.076×creatinine+2.398×dizziness-4.108×dark red tongue+4.169×pulse asthenia)],the model prediction rate was 90.5%.Conclusion The logistic regression model of coronary heart disease with blood stasis evidence is good with clinical diagnosis,which lays the foundation for the exploration of the state between the already diseased and undiseased of coronary heart disease,and provides important basic data for the theory of subhealth.

Objective:To evaluate the effects of mind-body exercise on breast cancer patients using a Meta-analysis.Methods:Randomized controlled trials (RCTs) on the effects of mind-body exercises on breast cancer patients were systematically searched in PubMed, Cochrane Library, Embase, Web of Science, China National Knowledge Infrastructure, WanFang data, VIP, and China Biology Medicine disc, with a search period from database inception to November 30, 2023. The references of the included studies were also reviewed. After two reviewers independently screened the literature, extracted information, and evaluated the quality of the included studies, a Meta-analysis was performed using RevMan 5.3 software.Results:A total of 23 RCTs involving 1 730 breast cancer patients were included. The Meta-analysis showed that, compared to conventional care, mind-body exercise significantly reduced anxiety in breast cancer patients [ SMD=-0.46, 95% CI (-0.71, -0.21), P<0.01], as well as in those undergoing chemotherapy [ SMD=-0.30, 95% CI (-0.54, -0.07), P=0.01]. Mind-body exercise also alleviated depression in breast cancer patients. Subgroup analysis found that the Baduanjin group [ SMD=-1.13, 95% CI (-1.63, -0.64), P<0.01] was more effective in alleviating depression than the yoga group [ SMD=-0.24, 95% CI (-0.41, -0.07), P<0.01]. However, there was no statistically significant effect of mind-body exercise on improving the quality of sleep in breast cancer patients [ SMD=-0.41, 95% CI (-0.89, 0.06), P=0.09]. In terms of the effect of mind-body exercise on fatigue levels in breast cancer patients, subgroup analysis showed that Baduanjin [ SMD=-0.91, 95% CI (-1.26, -0.55), P<0.01] and Tai Chi [ SMD=-0.57, 95% CI (-0.92, -0.21), P<0.01] significantly reduced fatigue levels, while yoga [ SMD=-0.43, 95% CI (-0.98, 0.12), P=0.13] did not show a statistically significant effect on reducing fatigue levels in breast cancer patients. Conclusions:Mind-body exercises can reduce anxiety and depression and alleviate the level of fatigue in breast cancer patients. However, the effects of different exercise modalities on improving sleep quality in breast cancer patients vary.

Objective:To investigate the effects of different analgesic methods of hydromorphone on analgesic efficacy and sleep quality in patients with refractory cancer pain.Methods:Sixty patients with refractory cancer pain who received three-step analgesic treatment in Quzhou People's Hospital from August 2018 to December 2019 and acquired poor analgesic effects were included in this study. They were randomly assigned to undergo either an intravenous patient-controlled analgesia with hydromorphone (HV group, n = 30) or an intrathecal patient-controlled analgesia with hydromorphone (HI group, n = 30) for 10 consecutive days. The analgesic efficacy in each group was evaluated using the numerical rating scale (NRS) before and 2, 4, 24, 48 hours, and 10 days after administration. The frequency of breakthrough pain (BTP) at each time point was recorded. The sedation effect of medication was evaluated using the Ramsay score. The sleep quality of patients was evaluated using the Pittsburgh sleep quality index (PSQI). The activities of CD 3+, CD 4+, and CD 4+/CD 8+ lymphocyte subsets were measured by flow cytometry at different time points. The adverse reactions within 10 days after treatment were observed and recorded. Results:Before and at each time point after treatment, there were no significant differences in NRS score, the frequency of BTP, Ramsay score, and PSQI score between the two groups (NRS score: t = 0.45, 0.91, 0.52, 1.19, 0.97, 1.92, all P > 0.05; frequency of BTP: t = 0.34, 1.88, 0.86, 1.71, 1.22, 0.76, all P > 0.05; Ramsay score: t = 0.56, 0.46, 0.63, 0.22, 0.99, 0.14, all P > 0.05; PSQI: t = 0.86, 1.25, 1.46, 1.05, 0.57, 1.93, all P > 0.05). At each time point after treatment, the activities of CD 3+, CD 4+, and CD 4+/CD 8+ cells increased in each group, and the activities of CD 3+, CD 4+, and CD 4+/CD 8+ cells in the HI group were significantly higher than those in the HV group (CD 3+: t = 3.72, 3.12, 2.85, 3.13, 2.44, all P < 0.05; CD 4+: t = 3.62, 2.45, 3.31, 3.19, 2.70; all P > 0.05; CD 4+/CD 8+: t = 3.10, 2.74, 2.83, 3.24, 3.41, all P < 0.05). The total incidence of adverse reactions was slightly, but not significantly, lower in the HI group than the HV group [14.00% (7/30) vs. 26.00% (13/30), χ2 = 2.70, P = 0.100]. Conclusion:Compared with intravenous administration of hydromorphone, intrathecal administration of hydromorphone can better effectively relieve pain, decrease the frequency of BTP, improve sleep quality, has a good sedative effect, improve immune function, and has fewer adverse reactions.

ObjectiveTo develop a deep learning system for early ultrasound screening of developmental dysplasia of the hip （DDH）， a new smart-hip ultrasound technique （S-hip）， and to validate its clinical application. MethodsWe selected 11，100 annotated and reviewed coronal ultrasound images of infant hips between November 2021 and August 2022， 8，100 of which were used for the training set and 3，000 for the test set， to build a S-hip deep learning system. To verify the consistency between the automated measurement by S-hip and the manual measurements by sonographers， 174 standard coronal ultrasound images of 87 infants' bilateral hips were acquired， then α angle， β angle and femoral head coverage （FHC） were measured by S-hip， an ultrasound expert and a resident. The measurement data and the time required for the measurements were recorded and statistically analyzed. Another 100 standard coronal ultrasound images of the hips were randomly selected and measured twice respectively by the ultrasound expert and resident to assess the intra-sonographer repeatability. ResultsThe intraclass correlation coefficient （ICC） （95% CI） values of α angle， β angle and FHC results measured by S-hip and ultrasound expert were 0.799 （0.738， 0.847）， 0.798 （0.737， 0.846） and 0.934 （0.954， 0.975）， respectively. Those values measured by the ultrasound expert and resident were 0.725 （0.645， 0.789）， 0.674 （0.583， 0.748） and 0.931 （0.908， 0.949）， respectively. The mean absolute errors （MAE） of α angle， β angle and FHC results between measurements by S-hip and ultrasound expert were 2.69 °， 4.43 ° and 2.47%， respectively. The time required for measurements by S-hip， ultrasound expert and resident was （1.59±0.36） s， （18.76±2.23） s and （19.45±2.76） s， respectively. The automated measurement by S-hip cost much shorter time than the manual measurements by sonographers and the difference was statistically significant （P<0.001）. The ICC （95% CI） values of α angle， β angle and FHC results between two measurements by the ultrasound expert were 0.943 （0.916， 0.961）， 0.959 （0.940， 0.972）， and 0.981 （0.971， 0.987）， respectively. Those values by the ultrasound resident were 0.884 （0.833， 0.921）， 0.921 （0.884， 0.946）， and 0.962 （0.944， 0.974）. ConclusionThe S-hip based on a deep learning system is a highly reliable automated technique to accurately measure α angle， β angle and FHC. Compared with ultrasound residents， S-hip allows for a more simplified and significantly quicker measurement， which may enhance the widespread use of hip ultrasound screening in infants.

Objective:To evaluate the effect of stroke volume variation (SVV)-guided fluid therapy on perioperative haemodynamics and tissue perfusion in the patients with end-stage renal disease (ESRD) undergoing parathyroidectomy.Methods:One hundred and twenty-one patients of either sex, aged 18-64 yr, of American Society of Anesthesiologists Physical Status classification Ⅲ, with body mass index of 18-28 kg/m 2, with ESRD undergoing elective parathyroidectomy, who received haemodialysis treatment within 24 h before surgery, were enrolled in this study. The patients were divided into standard restrictive fluid therapy group (group SRT, n=61) and goal-directed fluid therapy group (group GDT, n=60) using a random number table method. Group SRT received restrictive fluid therapy, with a continuous infusion of 0.9% normal saline at a rate of 4 ml·kg -1·h -1. Group GDT received goal-directed fluid therapy guided by SVV, and when the SVV≥10% lasted for 5 min, the 0.9% normal saline 3 ml/kg was infused within 5 min until SVV<10%. Systolic blood pressure (SBP) was maintained at ≥90 mmHg or mean arterial pressure(MAP) at ≥65 mmHg throughout the perioperative period in both groups. The intraoperative volume of fluid infused, usage rate and consumption of intraoperative vasoactive drugs were recorded, and arterial blood lactate (Lac) level, MAP, heart rate, cardiac output, and inferior vena cava collapse index (IVC-CI) after removal of endotracheal tube at the end of surgery were measured. MAP was continuously recorded within 12 h after surgery, and MAP variability (CV MAP) was calculated. The occurrence of cardiovascular and cerebrovascular events within 30 days after operation was also recorded. Results:Compared with group SRT, the intraoperative volume of fluid infused was significantly increased, the usage rate of ephedrine and norepinephrine was decreased, the consumption of ephedrine was reduced, and the percentage of postoperative IVC-CI<50% and cardiac output were increased, the percentage of Lac≥2.0 mmol/L and CV MAP were decreased ( P<0.05), and no significant change was found in the incidence of cardiovascular and cerebrovascular events within 30 days after surgery in group GDT ( P>0.05). Conclusions:Compared with restrictive fluid therapy, SVV-guided fluid therapy can optimize the perioperative hemodynamics and tissue perfusion in the patients with ESRD undergoing parathyroidectomy.

Population ageing has become a major social issue of concern worldwide in recent years, with significant implications for national economic and social development. Globally, Singapore is one of the first countries to address ageing as a population issue and has implemented relatively well-developed initiatives to promote healthy ageing. Similar to China, Singapore has a sharp decline in the total fertility rate, resulting in changes in the population structure. This paper briefly introduces Singapore′s healthy ageing measures, summarizes Singapore′s practical measures and coping concepts in scientific research on ageing, healthcare programs for the elderly, elderly -friendly environment construction, artificial intelligence big data application, and puts forward that China should pay attention to the effectiveness of population growth incentive measures, pay attention to the scientific and technological response, increase the development and application of artificial intelligence, improve primary health care and long-term health care, and update scientific concepts.
