This paper　explored the disease mechanism of autism spectrum disorders （ASD） from the perspectives of “vital activity” and “qi configuration”， and it is believed that “vital activity” represents the internal regulatory mechanisms of the human body， while “qi configuration” represents the ability of the body to communicate and adapt to the external environment. Abnormal genetic factors lead to the extinction of vital activity in children with ASD， resulting in increased susceptibility to ASD. Environmental instability leads to the solitary qi configuration in ASD， triggering and exacerbating the manifestations of ASD on the basis of genetic susceptibility. In addition， epigenetic mechanisms also play an important role in the pathogenesis of ASD. Imbalances in vital activity and disruptions in qi configuration result in failure in qi transformation of zang-fu organs， with abnormal symptoms manifested through the five orifices. It is proposed that the treatment of ASD should aim to achieve a harmonious interaction between “vital activity” and “qi configuration” to accelerate the recovery of affected children.

Tingli Dazao Xiefeitang is a classic formula for treating lung abscesses and thoracic fluid retention， recognized throughout history and included in the Catalogue of Ancient Classic Formulas （Second Batch）. This article employs bibliometric methods to investigate and analyze the source， origin， and key information of Tingli Dazao Xiefeitang， providing a theoretical basis for the development and application of this renowned formula. The results show that Tingli Dazao Xiefeitang first appears in Synopsis of the Golden Chamber （Jin Kui Yao Lue）， where three clinical applications are recorded. The original text clearly states that this formula is used to treat lung abscesses and thoracic fluid retention， with symptoms such as inability to lie down due to wheezing， chest and rib fullness， facial edema， inability to rest due to thoracic fluid retention， and cough inversion. This aligns with findings from ancient application research. In later generations， the methods proposed by ZHANG Zhongjing were predominantly used for medication and formulation. Modern applications of Tingli Dazao Xiefeitang focus primarily on the respiratory system， with pleural effusion being the most common condition. For the preparation and decoction， a single dose of 5 g of Descurainiae Semen Lepidii Semen （dried and mature seeds of Lepidium apetalum） processed as stir-fried seeds and 36 g of Jujubae Fructus （dried and mature fruit of Ziziphus jujuba） prepared as raw materials were recommended. Then 600 mL of water was added and Jujubae Fructus was first boiled until the volume reduced to 400 mL. After filtering out the residue， the supernatant was retained and mixed with stir-fried Descurainiae Semen Lepidii Semen， followed by boiling to 200 mL， which should be consumed all at once. This research provides a theoretical basis for the development and application of this formula.

Objective:To compare the efficacy and safety of providing nasogastric (NG), nasojejunal (NJ), and parenteral nutrition (PN) support to pancreatitis patients who were intolerant to oral feeding.Methods:One hundred pancreatitis patients who were intolerant to oral feeding treated at the Xuanwu Hospital of the Capital Medical University from October 2018 to September 2020 were retrospectively studied. They were divided into three groups based on the nutritional support given to them: the NG group, NJ group, and PN group. The acute physiology and chronic health evaluation Ⅱ(APACHEⅡ), nutritional risk screening 2002 (NRS2002), hemoglobin, albumin, pre-albumin and other clinical data were recorded and compared among the three groups.Results:After nutrition support treatments, the hemoglobin, albumin and pre-albumin levels were significantly better than before giving nutrition support, and the APACHE Ⅱ scores were significantly improved in all the groups. The NRS2002 scores were significantly better in the NJ group ( Z=2.28, P=0.023) and the NG group ( Z=1.99, P=0.046). With compared to the PN group, the albumin and pre-albumin levels were significantly higher in the NG and NJ groups, and the NRS2002 score after giving nutrition support treatment was significantly lower ( P<0.05). Compared with the PN group, the APACHE Ⅱ score ( t=2.18) and the hemoglobin levels ( t=2.04) were significantly better in the NJ group ( P<0.05). The overall incidence of complications in the NJ group was 41.2% (14/34), which was significantly lower than the NG group [78.8%(26/33), χ 2=5.41, P=0.020] and the PN group [66.7% (22/33), χ 2=4.35, P=0.037]. Conclusion:Enteral nutrition support through NG and NJ are better than PN in acute pancreatitis patients who were intolerant to oral feeding.

Objective:To systematically evaluate the methodological quality of screening guidelines for upper gastrointestinal cancer (including esophageal cancer and gastric cancer) both at home and abroad, and provide reference for the update of upper gastrointestinal cancer screening guidelines in China.Methods:Original articles and grey literature published as of 31 th Aug 2020 were retrieved using Chinese databases (CNKI, Wanfang, China Biomedical Literature Database and China Guideline Clearinghouse), PubMed, The Cochrane Library and Embase, as well as those from International Agency for Research on Cancer and the International Guide Collaboration Network. The inclusion criteria were being independent guidelines/recommendation documents for upper gastrointestinal cancer screening and meeting the definition of the institute of Medicine, USA. The exclusion criteria were being guideline abstracts, interpretation and evaluation literature, duplicate publications, updated original guidelines, and clinical treatment or practice guidelines for esophageal or gastric cancer. Appraisal of Guidelines for Research and Evaluation (AGREE Ⅱ) and Reporting Items for Practice Guidelines in Healthcare (RIGHT) were used to compare and evaluate the quality and reporting standard of esophageal or gastric cancer screening guidelines. Results:A total of 6 esophageal cancer screening guidelines and 5 gastric cancer screening guidelines were included. The results of the AGREE Ⅱ quality evaluation showed that the overall quality of eleven guidelines varied, including two guidelines recommended for "A", one for "B", five for "C" and three for "D". The guidelines had higher scores in the areas of scope and purpose, and clarity. The esophageal cancer screening guidelines had different scores in the areas of rigor and independence. The gastric cancer screening guidelines generally had low scores in the areas of participants and application. The RIGHT evaluation results showed that the quality of eleven guidelines should be improved. The six items with poor report quality were background, evidence, recommendations, review and quality assurance, funding and conflict of interest statement and management and others.Conclusion:The quality of the included upper gastrointestinal cancer screening guidelines is general, and the standardization needs to be strengthened.

Objective To evaluate the efficacy of the new treatment regimen versus the standardized scheme for the initial treatment of smear-positive tuberculosis in the elderly.Methods A total of 302 elderly patients meeting the inclusion and exclusion criteria were selected from 14 tuberculosis-designated medical institutions in Beijing.The patients received the initial treatment of smear-positive tuberculosis from January 2014 to August 2016 in the combined prospective and retrospective study.All patients were divided into observation group(n=63)receiving treatment with 6L2 HELfx regimen from August 1,2015 to August 31,2016,and control group (n =239) receiving treatment with 6L2HELfx regimen from January 1,2014 to January 31,2015.The nation-unified standard chemotherapy regimen 2RHZE/4RH was used in tuberculosis medical service institutions for all patients.The differences between the two groups were analyzed and compared in the completion of treatment,negative conversion of sputum culture or smear,adverse drug reactions and treatment outcome.Results The completion rate of long-course therapy was significantly higher in the observation group than in control group [90.5％ (57/63) vs.79.5％ (190/239),x2 =4.034,P =0.045].The rate of negative conversion of sputum culture or smear at the end of the 2nd month was higher in the observation group than in control group,but had no significant difference[87.0％ (47/54)vs.81.6％(155/190),x2 =0.879,P=0.349].The incidence of adverse reactions was much lower in observation group than in control group[46.0％ (29/63) vs.65.3％ (156/239),x2 =7.777,P =0.005].The success rate of treatment(cure or completion of long-course therapy)was higher in observation group than in control group [90.5％ (57/63) vs.77.4％ (185/239),x2 =5.350,P =0.021].ConclusioNS As compared with the standard chemotherapy regimen,the L and Lfxcontaining treatment regimen has better effects,higher success rate of treatment and less adverse reactions in elderly patients with the initial treatment of smear-positive tuberculosis.

Objective: To explore the diagnosis and treatment of head and neck Castleman′s disease (CD), and to improve the understanding of the disease. Methods: The clinical data of 41 patients with head and neck CD treated from January 2007 to July 2017 in the First Affiliated Hospital of Zhengzhou University were analyzed retrospectively. The patients were divided into two groups: localized CD (LCD, n=27) and multicentric CD (MCD, n=14). The clinical manifestations, laboratory examinations, operations, pathological findings and follow-up data were analyzed. Results: LCD was characterized by asymptomatic enlargement of the single lymph node with mild clinical symptoms. The main pathological type was hyaline vascular type, which can be cured by surgical treatment. MCD accompanied by fever 9 cases(64.3%), anemia 8 cases (57.1%), splenomegaly 7 cases (50.0%), respiratory symptoms 6 cases (42.9%), with multiple enlarged superficial and deep lymph nodes with pain, pleural effusion, and edema of lower extremity, C-reaction protein increased in 8 cases (57.1%), hypoproteinemia 8 cases(57.1%), globulin increased 7 cases (50.0%) and neutropenia 6 cases(42.9%). The main pathological type was plasma cell type in 7 cases (50.0%), and also there were 4 cases of hyaline vascular type and 2 cases of mixed type. Chemotherapy with or without rituximab was the main treatment. Most patients received complete or partial remission except for 2 patients who died of lung infection due to chemotherapy. Conclusions The diagnosis of head and neck CD depends on pathological examination. LCD shows mild symptoms and good prognosis after surgery. However, clinical manifestations of MCD are complex, with relatively poor prognosis after comprehensive treatment.

Objective To assess the epidemiological characteristics of hypertension and its attributing factors in Heilongjiang province and establish a comprehensive basis for the prevention and control of hypertension in this region. Methods Using the stratified chunk method, a survey lasting 50 years was conducted on a sample of 299 677 (including i 58 782 males and 140 895 females) patients, aged 15 and above, residing in both rural and urban areas of Heilongjiang province from 1958 to 2007. Both blood pressure measurement and analysis on attributing factors of hypertension were carried out in 1958, 1979, 1991, 1999 and 2007. Results The prevalence of hypertension was significantly higher in Heilongjiang than in other provinces. It elevated annually, reaching a 3-fold increase in 50 years with an accelerating pace ( 17.06% to 25. 69% ) in the recent 8 years. Among the people examined, the prevalence of hypertension increased with aging. Furthermore, the prevalence of hypertension varied among different professions. Office workers had the highest prevalence (41.67%). Compared with female population, male participants had a much higher prevalence before the age of 55 (P < 0.0001 ). Body mass index, gender, hypertriglyceridemia, age, low-high density lipoprotein cholesterol and family history were identified as major risk factors for the development of hypertension in Heilongjiang province. However, the awareness (48. 90% ), treatment (25.33%) and control (4. 32% ) rates of hypertension in this region were relatively low. Conclusion The results of the present study identified Heilongjiang province as a high-risk region for hypertension. It also suggests the necessity to plan and implement actions for the effective prevention and treatment of hypertension in this region.

To investigate whether the calcium channel blocker amlodipine could inhibit macrophage matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9) expression and secretion. Methods Peritoneal macrophages were isolated from BALB/C mice and incubated with low (5μg/L), middle (15μg/L) and high (305μg/L) concentrations of amlodipine, or in the medium alone (controls) for 24 hours, and the expression and secretion of MMP-2 and MM-9 of the cells were analyzed by RT-PCR and gelatin zymography. Results Compared with controls, amlodipine at low concentration had no significant effects on the expression and secretion of either MMP-2 and MMP-9 (P＞0.05);at middle concentrationit it could inhibited MMP-2 and MMP-9 expressions completely and significantly reduced the secretion of MMP-9 (P＜0.05); but it had no effect on the secretion of MMP-2. At high concentration it also inhibited MMP-2 and MMP-9 expression completely. Conclusion Amlodipine at 15 ìg/L inhibited the expression of MMP-2 and MMP-9 and reduced the secretion of MMP-9, suggesting that amlodipine may stabilize atherosclerotic plaque.

OBJECTIVETo assess the epidemiology features of hypertension in Heilongjiang Province, China.

METHODSFrom 1959 to 1999, 289,157 people in total, ages > or = 15-year old (male 154,091, female 135,066) were investigated four times by a stratified chunk method in rural and urban areas in Heilongjiang Province. After a staff training program, this survey on blood pressure and risk factors was carried out under a worldwide uniform protocol with standardized method and interrelated quality control regulation. Among these samples, 1615 people (male 824, female 791) received blood-lipid analysis.

RESULTSThe hypertensive incidence of Heilongjiang was much higher than the average level in China (P < 0.01) and it has gotten higher from 1959 to 1999, especially in the last ten years. It increased more in males than in females (P < 0.01). It was also higher with age. The mean age of hypertensive onset became ten years younger recently. It is different in different areas and professions. Age, BMI (body mass index), drinking alcohol, gender, history of maternal hypertension, high salt diet and professional status were the main risk factors for hypertension in Heilongjiang Province in China.

CONCLUSIONThe prophylaxis and treatment of hypertension should be enhanced in this area.
