Objective To observe the clinical efficacy of meridian massage in the treatment of lumbar disc herniation(LDH).Methods Between July 2020 and April 2023,82 patients with lumbar disc herniation were selected,including 58 males and 24 females,aged from 23 to 55 years old with an average of(43.76±6.64)years old.According to the different treatment methods,they were divided into observation group and control group with 41 cases in each group.The control group was treated with routine treatment,and the observation group was treated with meridian massage on the basis of routine treatment.In the control group,there were 30 males and 11 females;aged from 22 to 52 years old with an average of(42.27±9.34)years old;the Body mass index(BMI)ranged from 19 to 28 kg·m-2 with an average of(23.82±1.08)kg·m-2;the course of disease ranged from 0.5 to 3.0 years(2.40±0.48)years.There were 28 cases in L4,5 segment and 13 cases in L5S1 segment.In the observation group,there were 28 males and 13 females;the age ranged from 19 to 54 years old(42.19±9.26)years old;the BMI ranged from 18 to 29 kg·m-2 with an average of(23.73±1.15)kg·m-2;the course of disease ranged from 0.6 to 2.8 with an average of(2.56±0.45)years;there were 26 cases in L4,5 segment and 15 cases in L5S1 segment.Visual analogue scale(VAS),Oswestry disability index(ODI),M-JOA score and TCM syndrome score were measured before and after 3 courses of treatment,and the clinical efficacy was evaluated by the standard of curative effect evaluation.Results After treatment,VAS[(3.24±1.45)vs(4.46±0.64)],ODI[(11.45±1.98)％vs(17.21±2.74)％]and TCM symptom score[(2.03±0.27)vs(3.99±0.54)]of the observation group were lower than those of the control group.The score of M-JOA[(23.43±2.61)vs(19.37±1.62)]increased(P＜0.05).The scores of VAS,ODI andTCM symptoms in the observation group were lower than those in the control group,while the scores of M-JOA were higher than those in the control group(P＜0.05).Conclusion Meridian massage is effective in the treatment of LDH,which can effectivelyrelieve low back pain,improve clinical symptoms and increaselumbar function,which is worthy of clinical promotion.

This study explored the feasibility of mineral element content and ratios of nitrogen isotopes to discriminate the cultivation mode of Dendrobium nobile in order to provide theoretical support for the discrimination of the cultivation mode of D. nobile. The content of 11 mineral elements(N, K, Ca, P, Mg, Na, Fe, Cu, Zn, Mn, and B) and nitrogen isotope ratios in D. nobile and its substrate samples in three cultivation methods(greenhouse cultivation, tree-attached cultivation, and stone-attached cultivation) were determined. According to the analysis of variance, principal component analysis, and stepwise discriminant analysis, the samples of different cultivation types were classified. The results showed that the nitrogen isotope ratios and the content of elements except for Zn were significantly different among different cultivation types of D. nobile(P<0.05). The results of correlation analysis showed that the nitrogen isotope ratios, mineral element content, and effective component content in D. nobile were correlated with the nitrogen isotope ratio and mineral element content in the corresponding substrate samples to varying degrees. Principal component analysis can preliminarily classify the samples of D. nobile, but some samples overlapped. Through stepwise discriminant analysis, six indicators, including δ~(15)N, K, Cu, P, Na, and Ca, were screened out, which could be used to establish the discriminant model of D. nobile cultivation methods, and the overall correct discrimination rates after back-substitution test, cross-check, and external validation were all 100%. Therefore, nitrogen isotope ratios and mineral element fingerprints combined with multivariate statistical analysis could effectively discriminate the cultivation types of D. nobile. The results of this study provide a new method for the identification of the cultivation type and production area of D. nobile and an experimental basis for the quality evaluation and quality control of D. nobile.

OBJECTIVE: To study the effect of ultrasound-guided fascia iliaca compartment block on perioperative analgesia and postoperative complications in geriatric patients with hip fractures. METHODS: A total of 127 elderly patients undergoing hip fracture surgery from January 2021 to September 2021 were randomized to receive ultrasound-guided continuous fascia iliaca compartment block(group F) either intravenous analgesia control group(group C). There were 62 cases in group F, including 19 males and 43 females with an average age of (82.4±7.2) years old ranging from 66 to 95 years old, involving 25 femoral neck fractures and 37 femoral intertrochanteric fractures. There were 65 cases in control group, including 18 males and 47 females, with an average age of (81.4±8.7) years old ranging from 65 to 94 years old, involving 29 femoral neck fractures and 36 femoral intertrochanteric fractures. The visual analogue scale(VAS), minimental state examination (MMSE), observer's assessment of alertness/sedation(OAA/S) scale, modified Bromage score, postoperative complications and general conditions during hospitalization in two groups were observed. RESULTS: The resting and exercise VAS at 30 min after block, anesthesia placement and 6, 24 and 48 h after surgery were lower than those in group C(P<0.05). In group F, MMSE scores at 12 h before surgery, and 1, 3 d after surgery and OAA/S scores at 3 d after surgery were higher than those in group C(P<0.05). The incidence of adverse effects and the number requiring additional analgesia were lower than those in group C(P<0.05). Group F had better perioperative analgesia satisfaction and hospital stay than group C(P<0.05). But there was no significant difference regarding Bromage score and 30-day mortality between two group(P>0.05). CONCLUSION Ultrasound-guided continuous fascia iliacus space block was safe and effective for elderly patients with hip fracture, and could significantly reduce perioperative pain, improve postoperative cognitive function, and reduce postoperative complications, thereby shortening hospital stay and improving the quality of life during hospitalization.

Since the end of 2019,severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection has swept the world,bringing great harm to human society and significantly increasing the health burden.Due to stron-ger infectivity,faster transmission,and higher reinfection rate of the Omicron variant,it has now replaced the Delta variant as the main epidemic strain for both imported and local outbreaks in China.Chinese Diagnosis and treatment protocol for SARS-CoV-2 infection(10th trial version)emphasizes"strengthening the protection of key popula-tions,"which includes the increasing number of immunocompromised population.These people have a high inci-dence of severe diseases and a high fatality rate after infected with SARS-CoV-2,and belong to the high-risk popula-tions of severe or critical diseases.Moreover,due to underlying diseases,these people take immunosuppressants and other related drugs chronically.The interactions between anti-SARS-CoV-2 infection treatment drugs and origi-nal drugs are complicated,thus bring significant challenges to the treatment after the SARS-CoV-2 infection.Cur-rently,there is a lack of guidelines or consensus on the diagnosis and treatment of SARS-CoV-2 infection among im-munocompromised population.Therefore,the Guangzhou Institute of Respiratory Health and National Center for Respiratory Medicine organized experts from multiple disciplines(respiratory and critical care medicine,organ transplantation,rheumatology and immunology,hematology,infection,critical care medicine,etc.)in China.Af-ter multiple rounds of discussions,13 items of recommendations are made as the reference for peers based on evi-dence-based medical evidence,so as to provide a theoretical and practical reference for the diagnosis and treatment strategies of this population.

Aim To investigate the effect of microinjection of EX527, a selective SIRT1 antagonist, into the ventrolateral orbital cortex (VLO) on morphine-induced conditioned place preference (CPP), and to explore the role of CREB/BDNF in it. Methods The cannulas were implanted bilaterally in the VLO of rats by brain stereotaxis surgery, and the model of morphine-induced CPP was established. The behavioral experiment consisted of four stages:habituation (d 1), pre-test (d 2-4), conditioning training (d 5-14) and test (d 15). At the stage of conditioning training, EX527 (1 μL, 5 g·L

Since the 18th National Congress of the Communist Party of China(CPC), the CPC and the government have highligh-ted the development of traditional Chinese Medicine(TCM) and issued a series of policies, such as the Plan for Protection and Deve-lopment of Chinese Medicinal Materials(2015-2020) forwarded by the General Office of the State Council in 2015, the Plan for Healthy Development of Traditional Chinese Medicine(2015-2020) released by the General Office of the State Council in the same year, the Healthy China 2030 Plan published by the CPC Central Committee and the State Council in 2016, the Law of the People's Republic of China on Traditional Chinese Medicine which took effect on July 2017, On the Preservation and Innovative Development of Traditional Chinese Medicine promulgated by CPC Central Committee and the State Council in 2019, and Plan for the Development of Traditional Chinese Medicine during the 14th Five-Year Plan Period of China released by the General Office of the State Council in March 2022, to promote the development of the TCM industry, which have brought historical opportunities to the TCM industry. However, TCM industry faces various challenges in the development. In terms of drug development in TCM, the current studies mainly focused on the chemical research and technical requests, which neglected TCM characteristics and cased in conformity between new drug transformation of TCM and clinical practice. Therefore, a more considerable and profound authoritative guideline is needed, and innovative thought and research are necessary for academics and the industry. Through the investigation of the development TCM industry in recent years, this study summarized the policies on and trends of Chinese medicinal materials, new drug development in TCM, catalogue of national basic drugs, and national basic health insurance, and proposed suggestions for further development of TCM industry.

Through consulting the ancient herbs， medical books and modern literature， this paper made textual research on the name， origin， producing area， quality evaluation， collection and processing of medicinal materials of Sang （Mori Folium， Mori Cortex， Mori Ramulus， Mori Fructus） in famous classical formulas， in order to provide a basis for the development of famous classical formulas containing medicinal materials of Sang. According to the research， Mori Folium and Mori Cortex were first used as medicines in Shengnong Bencaojing ， Mori Ramulus was first used as medicine in Jinxiaofang， and Mori Fructus was first used as medicine in Xinxiu Bencao. Before the Tang dynasty， there were Nyusang and Shansang. Since Tang dynasty， there were many sources of medicinal materials of Sang， including Baisang （Morus alba）， Jisang （M. australis）， Shansang （M. mongolica）， etc. According to textual research， the mainstream varieties were M. australis， M. alba and their cultivated varieties. In modern times， according to the relevant information and the Chinese Pharmacopoeia， M. alba is the original base. In ancient times， the origin of mulberry changed with the development of sericulture， mulberry has been widely planted since the Song dynasty. In the Ming and Qing dynasties， mulberry has been planted most in Jiangsu and Zhejiang. In modern times， they are mainly produced in Jiangsu， Zhejiang， Anhui， Hunan and other places. In recent years， due to the related policies and strategies such as "moving silkworms from east to west"， the center of silkworm breeding has gradually transferred to the west. As for the quality evaluation and harvesting and processing of mulberry medicinal materials， Most of the ancient and modern records of Mori Folium are the same. They are harvested after frost， and dried after removing impurities. The quality is better when the leaves are large and thick， yellowish green， holding prickly hands and undergoing frost. The harvesting period of Mori Cortex is slightly different in ancient and modern records. Ancient books record that it can be harvested all the year round， but in modern times， it is mostly harvested from late autumn to the next spring. The processing methods include removing soil and fibrous roots， scraping off yellow-brown rough skin， peeling off white skin and drying in the sun. The quality is better when they are white， thick， flexible， free of rough skin and full of powder. There are few records about the collection， processing and quality evaluation of Mori Ramulus and Mori Fructus in ancient Chinese herbal books. According to modern literature， Mori Ramulus is usually collected in late spring and early summer， with leaves removed， slightly dried， sliced while fresh， and dried in the sun. The best quality of Mori Ramulus is fine and tender with the yellow and white section. Mori Fructus is harvested from April to June when the fruit turns red， and dried in the sun， or slightly steamed and dried in the sun， and it is better to be big， dark purple， oily and thick. There are many processing methods of mulberry medicinal materials. Ancient books record stir frying， baking， burning and steaming of Mori Folium， in modern times， there is honey-roasted method， but most of them are used as raw products. In ancient materia medica， Mori Cortex has firing method， baking method， stir-frying method， honey-fried method， etc. In modern times， there are stir-fried and honey-fried methods， and most of them are used as raw products. Ancient books record that Mori Ramulus has cutting and frying methods， while modern ones have cutting， frying， wine-processed and bran-processed methods. Processing methods of Mori Fructus are consistent in ancient and modern times， and they are mostly dried after being cleaned or steamed. Based on the research results， it is suggested that M. alba should be selected as mulberry medicinal materials in the famous classical formulas， and appropriate medicinal parts and processing methods can be selected according to the indications of the famous classical formulas.

Objective: To investigate the clinical, cardiac imaging characteristics and prognosis of patients with primary cardiac angiosarcoma. Methods: The clinical data of 14 patients hospitalized with primary cardiac angiosarcoma from January 2001 to December 2017 in Peking Union Medical College Hospital were collected and analyzed. Metastatic cardiac angiosarcoma was not included in this study. Patients were followed up post discharge per telephone call or clinical visit. Results: Of the 14 patients, 8 were males and 6 were females, average age was 48 years. The main clinical symptoms were shortness of breath (8/14), hemoptysis (6/14), fever (5/14), chest pain (4/14) and cough (3/14). Imaging examinations showed that the tumors of 8 patients were located in the right heart and 6 in the pericardial cavity. Tumors in the right heart often infiltrate the atrial wall and cause pericardial effusion (7/8). Tumors in the pericardium were characterized by recurrent bloody pericardial effusion (6/6), prone to progressive constrictive pericarditis (3/6), pericardial fluid cytology was often negative (6/6). MRI showed heterogeneous high signal intensity (cauliflower aspect) on T2-weighted image and heterogeneous enhancement with a"sunray" aspect at the perfusion study. At the time of diagnosis, 8 patients developed lung or adrenal metastasis (8/14). The median survival was only 305 days. Conclusions: Primary cardiac angiosarcoma is a rare disease with non-specific clinical manifestation and poor prognosis. Imaging examinations may help diagnosis. The high invasiveness and the easy-to-metastasis feature of the tumor contribute to the poor prognosis of cardiac angiosarcoma.

Objective: Long-term seroprotection the hepatitis A vaccine is essential for the prevention of disease from the hepatitis A virus (HAV). Due to documented difficulties during decade-long follow-ups after receiving vaccines, statistical-modeling approaches have been applied to predict the duration of immune protection. Methods: Based on five-year follow-up data from a randomized positive-controlled trial among Chinese children (1-8 years old) following a 0, 6 months vaccination schedule, a power-law model accounting for the kinetics of B-cell turnover, as well as a modified power-law model considering a memory-B-cell subpopulation, were fitted to predict the long-term immune responses induced by HAV vaccination (Healive or Havrix). Anti-HAV levels of each individual and seroconversion rates up to 30 years after vaccination were predicted. Results: A total of 375 participants who completed the two-dose vaccination were included in the analysis. Both models predicted that, over a life-long period, participants vaccinated with Healive would have close but slightly higher antibody titers than those of participants vaccinated with Havrix. Additionally, consistent with previous studies, more than 90% of participants were predicted to maintain seroconversion for at least 30 years. Moreover, the modified power-law model predicted that the antibody titers would reach a plateau level after nearly 15 years post-vaccination. Conclusions Based on the results of our modeling, Healive may adequately induce long-term immune responses following a 0, 6 months vaccination schedule in children induction of memory B cells to provide stable and durable immune protection.

To scientifically evaluate the intervention effect of Chinese medicine preventive administration(combined use of Huo-xiang Zhengqi Oral Liquid and Jinhao Jiere Granules) on community population in the case of coronavirus disease 2019(COVID-19), a large cohort, prospective, randomized, and parallel-controlled clinical study was conducted. Total 22 065 subjects were included and randomly divided into 2 groups. The non-intervention group was given health guidance only, while the traditional Chinese medicine(TCM) intervention group was given two coordinated TCM in addition to health guidance. The medical instructions were as follows. Huoxiang Zhengqi Oral Liquid: oral before meals, 10 mL/time, 2 times/day, a course of 5 days. Jinhao Jiere Granules: dissolve in boiling water and take after meals, 8 g/time, 2 times/day, a course of 5 days, followed up for 14 days, respectively. The study found that with the intake of medication, the incidence rate of TCM intervention group was basically maintained at a low and continuous stable level(0.01%-0.02%), while the non-intervention group showed an overall trend of continuous growth(0.02%-0.18%) from 3 to 14 days. No suspected or confirmed COVID-19 case occurred in either group. There were 2 cases of colds in the TCM intervention group and 26 cases in the non-intervention group. The incidence of colds in the TCM intervention group was significantly lower(P<0.05) than that in the non-intervention group. In the population of 16-60 years old, the incidence rate of non-intervention and intervention groups were 0.01% and 0.25%, respectively. The difference of colds incidence between the two groups was statistically significant(P<0.05). In the population older than 60 years old, they were 0.04% and 0.21%, respectively. The incidence of colds in the non-intervention group was higher than that in the intervention group, but not reaching statistical difference. The protection rate of TCM for the whole population was 91.8%, especially for the population of age 16-60(95.0%). It was suggested that TCM intervention(combined use of Huoxiang Zhengqi Oral Liquid and Jinhao Jiere Granules) could effectively protect community residents against respiratory diseases, such as colds, which was worthy of promotion in the community. In addition, in terms of safety, the incidence of adverse events and adverse reactions in the TCM intervention group was relatively low, which was basically consistent with the drug instructions.
