ObjectiveTo observe the effects of acupuncture at channel points in treating functional dyspepsia （FD） patients of spleen-stomach weakness syndrome and to explore its potential mechanism. MethodsSixty FD patients of spleen-stomach weakness syndrome were randomly divided into an acupuncture group and a domperidone group， with 30 patients in each group. Acupuncture group was given acupuncture at Zusanli （ST36）， Neiguan （PC6）， Gongsun （SP4）， and Yinlingquan （SP9） using even reinforcing-reducing method. Unilateral points were selected alternately on the left and right sides， once daily， for 30 minutes each session， 5 sessions per course， and a 2-day interval between courses. Domperidone group was given domperidone tablets orally， one tablet each time， three times daily， 15~30 minutes before meals. The total course of treatment was 4 weeks in both groups. Pairwise comparisons of the symptom scores including postprandial fullness and discomfort， early satiety， epigastric pain， and epigastric burning discomfort， and the levels of serum 5-hydroxytryptamine （5-HT）， vasoactive intestinal peptide （VIP）， and glucagon-like peptide-1 （GLP-1） were conducted at pre-treatment， 4， and 8 weeks post-treatment. The clinical efficacy was analyzed and evaluated after treatment. ResultsCompared with baseline， the symptom scores of postprandial fullness and discomfort， early satiety， epigastric pain and epigastric burning discomfort and the levels of serum 5-HT， VIP and GLP-1 of both groups were significantly decreased after 4 weeks and 8 weeks treatment （P＜0.05）. At 4 weeks post-treatment， all symptom scores and the levels of 5-HT and GLP-1 of the acupuncture group were significantly lower than those of the domperidone group （P＜0.05）. At 8 weeks post-treatment， the symptom scores of postprandial fullness and discomfort， early satiety and epigastric pain and the levels of 5-HT and VIP of the acupuncture group were significantly lower than those of the domperidone group （P＜0.05）. The total effective rate of the acupuncture group （96.67%， 29/30） was higher than that of the domperidone group （86.67%， 26/30， P＞0.05）. ConclusionAcupuncture at channel points shows good clinical efficacy in the treatment of spleen-stomach weakness syndrome FD， and its mechanism may be related to the decreased levels of 5-HT， VIP， and GLP-1 in serum.

Rosacea is a chronic facial inflammatory skin disease. It has been proved that heredity, immunity, neurovascular disorders, microorganisms, skin barrier damage and ultraviolet rays are closely related to the occurrence of rosacea. However, the exact pathogenesis of rosacea has not been fully elucidated. This review summarizes recent advances in the pathogenesis of rosacea in the past 5 years.

The theory of “diagnosing diseases with sinews” means that through the diagnosis and examination of the channel sinews at the site of the lesion， the surplus and deficit state of qi and blood in the channel sinews， vessles and channels， and the degree of damage to the organism caused by the disease and evils， can be determined， forming the three elements （the nature of the disease， the location of the disease， and the disease tendency） of the disease diagnosis can be closely integrated to form the trinity of diagnostic modes， which is “examining the disease nature by sinews， identifying the pattern by sinews， and determining the tendency by sinews”. For intractable facial paralysis， the method of “diagnosing diseases with sinews” can be adopted， in which the morphological changes of the channel sinews are judged through diagnosis by observation， the traditional Chinese patterns are identified through diagnosis by palpation， and the points of meridian tendons and the circulation of tendon and treatment lines are determined through diagnosis by circulation. The “diagnosing diseases with sinews” not only helps to accurately determine the disease condition， patterns and development trend， but also helps to adopt targeted treatment for the disease and prevent the disease from spreading， and providing ideas and methods for the clinical diagnosis and treatment of intractable facial paralysis.

Cancer stem cells(CSCs)are a small group of cells found in tumors that have same self-renewing properties as nor-mal stem cells.In recent years,with continuous development of science and technology in various aspects,people's research on tumor diseases has been deepened.CSCs has been defined as a key factor in promoting tumor development,especially participating in pro-moting tumor recurrence,metastasis,chemotherapy resistance,etc.Currently,CD133 has become one of popular CSCs markers,and can be highly expressed in a variety of CSCs.CD133 is closely related to diagnosis of cancer diseases,and plays an important role in dignosis and drug targeting for gastric cancer,lung cancer,brain tumor,liver cancer,ovarian cancer and colorectal cancer.This article reviews structure,function,immune mechanism escape of CD133,signal pathway of CD133 in tumorigenesis,and correlation of CD133 with various tumors as well.

A case of giant liquid tophus in both lower legs was reported. The patient was a 41-year-old man with a history of gout for more than 10 years. The patient had hyperlipidemia and prediabetes, and the long-term use of hormone cortisol drugs was suspected. After standardized treatment for lowering uric acid, reducing blood lipids, and correcting glucose intolerance, the patient lost 12 kg over six months. The patient was admitted to the hospital upon discovering symmetrical enlargement of both calves. Ultrasound showed subcutaneous masses with clear boundaries behind the gastrocnemius muscle, approximately 14.9 cm×6.7 cm on the left and 13.6 cm×4.6 cm on the right. Based on the clinical information and morphological features, a diagnosis of gouty tophus was made. Following ultrasound-guided puncture drainage, aspirate about 200 mL fluid from the subcutaneous masses of each lower legs. The patient continued to receive standardized uric acid-lowering treatment and the patient′s condition improved. For such atypical giant liquid tophus, clinical practitioners should remain vigilant, differentiating them from tumors, infections, autoimmune diseases, and promptly perform pathological examinations through puncture to be diagnosed. After a definitive diagnosis, surgical excision can be performed concurrently with standardized uric acid-lowering treatment to achieve a favorable prognosis.

Osteoporosis （OP） and osteoarthritis （OA） are common bone diseases in clinic. OP is a systemic skeletal disease， and OA is a chronic degenerative joint disease with high prevalence and disability rates. With the advent of the aging population， the incidence rate of OA and OP is increasing year by year， and they have become common diseases of the elderly. The quality of life and physical and mental health of patients are severely affected by the above two bone diseases. Chinese medicine has a long history of treating bone diseases， with a good clinical effect on preventing and treating OP， OA， and other bone diseases with few side effects. It is one of the commonly used methods to treat bone diseases. Polysaccharides， as one of the active substances of Chinese medicine， have various pharmacological activities and a wide range of sources with low toxicity， and their effect cannot be ignored. The role of polysaccharides in the treatment of bone diseases has been deeply studied. It has been found that the mechanism of Chinese medicine polysaccharides in treating OP and OA involves multiple levels， targets， and pathways. Through the analysis and summary of the relevant literature on the mechanism of Chinese medicine polysaccharides in treating OP and OA， it was found that Chinese medicine polysaccharides mainly treated OP by regulating the bone dynamic balance between osteoblasts and osteoclasts and affecting bone marrow mesenchymal stem cells and bone microstructure. The mechanism of Chinese medicine polysaccharides in the treatment of OA is related to the regulation of chondrocyte growth， the increase in the proteoglycan and collagen content in the cartilage matrix， and the reduction of oxygen free radical content and inflammatory mediator level. This study aimed to further explore the internal relationship among mechanisms of Chinese medicine polysaccharides in the treatment of bone diseases， to provide relevant ideas for the study of Chinese medicine polysaccharides in the treatment of bone diseases.

Based on the resutls of literature review and interviews of experts, two rounds of Delphi surveys were conducted. The mean, importance ratio, coefficient of variation and coordination coefficient were used for assessment of survey from multiple perspectives, and finally form a framework model of factors affecting the efficacy of Tuina therapy. A total of 37 experts were selected for questionnaire surveys, the positive coefficients of experts' participatation in the first round and second round were 92.5% and 80.0%, respectively. The overall coordination coefficient in the second round is 0.68. The items were included into the consensus meeting if the importance ratio of items were equal to and more than 80%. After the expert consensus meeting, 22 items were included to form a framework model of factors affecting the efficacy of Tuina therapy, and summarized as 5 major influencing factors, including diagnostic factors, treatment factors, prognostic factors, patient factors, and doctor-patient communication. This framework can guide and help young Tuina practitioners to improve clinical efficacy. It is also clearly pointed out that the effect of Tuina for pain is not only related to disease diagnosis or manipulation, but also related to home exercise, health care, and doctor-patient communication.

Objective: To investigate the effect of silencing human leukocyte⁃associated antigen⁃G ( HLA⁃G) expression in the chorionic trophoblast cell line JEG⁃3 cells under hypoxic conditions on the biological function of JEG⁃3 cells and through the hypoxia response pathway of endothelial PAS1 region protein 1 (EPAS1)is involved in the molecular mechanism of preeclampsia under high altitude hypoxia. Methods: The expression of HLA⁃G in JEG⁃3 cells was inhibited by transfection of small interfering RNA (siRNA) . The JEG⁃3 cells after transfection were divided into four groups : normoxic control group , hypoxic control group , normoxic inhibition group , and hypoxic inhibition group. CCK⁃8 test and Transwell test were used to detect the proliferation and invasion ability of the cells in four groups ; The effects of four groups of apoptosis and cell cycle were detected by flow cytometry; HLA⁃G and EPAS1 mRNA and protein expression levels were detected by real⁃time fluorescence quantitative PCR ( qPCR) and Western blot. Results : ① Compared with the normoxic control group , hypoxic control group , normoxic inhibition group , and hypoxic inhibition group could reduce the proliferation activity and invasion ability of JEG⁃3 cells , and significantly increase the apoptosis rate. The hypoxic control group and hypoxic inhibition group also produced anobvious necrotic cell population ; Under the condition of hypoxia , after reducing the expression of HLA⁃G , the cell necrosis rate was further aggravated ; Whether under normoxia or hypoxia , inhibition of HLA⁃G expression caused the cells to be blocked in the G1 phase. ② Compared with the normoxic control group , hypoxia control group , normoxic inhibition group , and hypoxia inhibition group decreased the expression of HLA⁃G protein , and hypoxia and inhibition of HLA⁃G had a synergistic effect; Hypoxia⁃inducible factors⁃2α ( HIF⁃2α ) , vascular endothelial growth factor(VEGF) and endothelin⁃1(ET⁃1) protein expression could be added , inhibition of HLA⁃G decreased the expression of inducible nitric oxide synthase( NOS2) . Conclusion In the hypoxic environment , silencing HLA⁃G may affect the biological behavior of trophoblast through the EPAS1 hypoxic response pathway and participate in the occurrence and development of preeclampsia.

A case of Streptococcus suis sepsis and streptococcal toxic shock syndrome diagnosed by metagenomic next-generation sequencing (mNGS) was presented. A 50-year old male patient visited Zengcheng Branch of Nanfang Hospital on June 25th, 2021. The patient developed fever, dizziness and shock with typical epidemiological history. mNGS revealed Streptococcus suis in blood sample. The diagnosis of Streptococcus suis sepsis and streptococcal toxic shock syndrome were made. Meropenem was given as empirical antibiotics. Antibiotics were adjusted to meropenem and clindamycin while Streptococcus suis was detecting by mNGS and downgraded to piperacillin/tazobactam and clindamycin when symptoms improved. The diagnosis was then confirmed by blood culture. The patient developed dry gangrene and sudden deafness in the later stage and was discharged after treatment. Compared with traditional diagnostic techniques, mNGS has advantages such as timeliness and accuracy, and plays a key role in the field of severe infections and rare pathogen infections. It is suggested that combining mNGS and traditional diagnostic techniques have the advantages for early diagnosis and early treatment.

Objective:To determine the effects of menopausal stage, age and other associated risk factors on symptoms of anxiety and depression among women in a community in Beijing.Methods:This study was a community-based prospective cohort. Participants who had transitioned through natural menopause, completed two or more depressive and anxiety symptoms evaluations, aged 35 to 64 years, and did not use hormone therapy were selected from the Peking Union Medical College Hospital aging longitudinal cohort of women in midlife to this analysis. The primary outcome variables were depressive and anxiety symptoms, assessed by hospital anxiety and depression scale (HADS). The generalized estimation equation was used in the statistical analysis.Results:Followed up from 2006 to 2014, 430 women and 2 533 HADS assessments were retained in the cohort. Depressive symptoms were more common than anxiety symptoms during all menopausal stages. The incidences of depressive and anxiety symptoms were 14.5% (19/191) and 3.1% (4/191) in the premenopausal -3 stage, respectively. The incidence increased in both menopausal transition and postmenopausal stage, with the highest incidence in the +1c stage [20.6% (155/751) and 8.8% (66/751), respectively]. However, these differences were not statistically significant (all P>0.05). Depressive symptoms were highest in the ≥60-<65 age group [20.8% (74/355)], and anxiety symptoms were highest in the ≥50-<55 age group [8.2% (62/754)]; but there were no statistical significances between different age groups and depressive and anxiety symptoms (all P>0.05). Multivariable analysis showed that high body mass index, low education status, and poor health status were independently associated with depressive symptoms (all P<0.05), and that poor health status, trouble falling asleep, and early awakening were independently associated with anxiety symptoms (all P<0.01). Conclusions:Depressive and anxiety symptoms are more common during menopausal transition and postmenopausal stage compared with reproductive stage. Depressive symptoms are more common than anxiety symptoms. To screen and assess depressive and anxiety symptoms in perimenopausal women is essential, especially for women with high risk factors.
