Arab countries have long tradition of using traditional medicine which enjoys mass foundation among local people. Recently, China's import and export trade of traditional medicine products with Arab countries showed an increasing trend year by year. With the implementation of the Belt and Road Strategy, Arab countries played a more important role in China's foreign trade. With the aim of promoting the spread of traditional Chinese medicine (TCM) in Arab countries, cooperation with relevant countries shall be differentiated. The Gulf region is economically advanced with its people enjoying prosperity, where is suitable for developing TCM product and service trade. The Levant has strong advantages in traditional medicine research, where academic communication shall be frequented. Countries in north Africa enjoy profound traditional friendship with China, where are suitable for dispatching Chinese foreign aid medical team to promote TCM. Meanwhile, we are supposed to take advantage of Confucius Institute and Chinese culture centers as platforms to spread TCM culture, to strengthen cooperation with medical universities and research institutions in the target countries, to enroll more Arab students to study TCM, to develop international standard Chinese-Arabic basic nomenclature of Chinese Medicine, and to carry out Traditional Arabic & Islamic Medicine researches.

Objective To observe the changes of carotid intima-media thickness(CIMT) and vascular endothelia function in patients with geriatric carotid plaque before and after intensive lipid lowering was performed.Methods 102 patients diagnosed with carotid plaque were ramdomly divided into common group (atorvastatin 10 mg/d,n=48) and intensive lipid lowering group (atorvastatin 20 mg/d,n=54).After one year of treatment,the fasting venous blood total cholesterol (TC),low density lipoprotein cholesterol (LDL-C),high density lipeprotein cholesterol (HDL-C) and triglyceride (TG) were assayed,and the thickest and thinnest CIMT and brachial arterial.endothelium dependent diastolic function (FMD) and carotid artery plaque index(PI) were measured by ultrasound.Results Two groups in the thickest CIMT and PI had no significant difference before and after treatment (P＞0.05).The levels of FMD,TC,LDL-C,TG and the thinnest CIMT had significant difference before and after therapy [common group:GIMT(0.85±0.20)mm,(0.83±0.22) mm,FMD(3.85±1.41)%,(7.91±1.05)%,TC(6.46±1.05) mmol/L,(4.82±1.26) mmol/L,LDL-C (4.71±1.00) mmol/L,(3.16±1.00) mmol/L,TG (1.55±0.45) mmol/L,(1.49±0.44) mmol/L;intensive lipid lowering group:CIMT(0.84±0.20) mm,(0.63±0.17) mm,FMD (3.74±1.38) %,(0.25±1.58)%,TC (6.36±1.06) mmol/L,(4.10±1.00) mmol/L,LDL-C (4.73±1.01) mmol/L、(2.28±1.26) mmol/L,TG (1.56±0.53) mmol/L,(1.50±0.49) mmol/L,P＜0.05].After one year's therapy,the difference in intensive lipid lowering group was more obvious than in common group (P＜0.05).Conclusions Intensive lipid lowering therapy is more effective to decrease TC,LDL-C and CIMT and to improve the vascular endothelia function.Atorvastatin is effective to stabilize the plaque and to retard the atheroscleresis development.

Objective To analyze the disease spectrum of patients admitted to the General Internal Medicine Unit at Peking Union Medical College Hospital, which is the first academic division of general internal medicine in the department of medicine within Chinese medical colleges and universities, and the value of general internal medicine unit in comprehensive hospitals. Methods A retrospective data review of patients admitted to the General Internal Medicine Unit from 2004 to 2008 was conducted from hospital information system and partially by chart review manually. Analysis of disease spectrum was performed thereafter. Results A total of 2593 patients were included in our study. It consisted of 1075 men and 1518women, with an average age of 45.1 years old. Forty point three percent of these patients were from Beijing,the local city, and the remaining 59.7% were from outside of Beijing. Sixty-four point nine percent (1683/2593)of these patients did not have a clear diagnosis on admission, including 758 fever of unknown origin (FUO) cases and 925 non-FUO cases. The final diagnostic rate of the FUO cases was 89. 2% [676/758, with the first three leading causes as diseases of the musculoskeletal system and connective tissue (29. 8%), certain infectious and parasitic diseases(26.3%), and neoplasm (14. 5%)] . The final diagnostic rate of the 928 non-FUO cases was 86. 8%(803/925), with the first three leading causes as musculoskeletal system and connective tissue(24.9%), neoplasm (15.5%), and diseases of blood and blood-forming organs(11.4%). Despite most diagnoses fitting into the above categories, the array of diseases was broad with as many as 550 discharge diagnoses from 2004 to 2008. Conclusions During 2004 -2008, there was a high proportion of cases that presented to the General Internal Medicine Unit at Peking Union Medical College Hospital with an unclear diagnosis, and the spectrum of diseases diagnosed was very broad. This kind of patient admitting model might not only benefit patients with no clear admission diagnosis and patients with multidisciplinary medical problems for whom it is usually difficult to be admitted by a specialty unit, but would also benefit medical students and residents by providing a good clinical medicine teaching base. These features show the value of general internal unit in comprehensive hospitals.

The central nervous system (CNS) plays a key regulatory role in glucose homeostasis. In particular, the brain is important in initiating and coordinating protective counterregulatory responses when blood glucose levels fall. This may due to the metabolic dependency of the CNS on glucose, and protection of food supply to the brain. In healthy subjects, blood glucose is normally maintained within a relatively narrow range. Hypoglycemia in diabetic patients can increase the risk of complications, such as heart disease and diabetic peripheral neuropathy. The clinical research finds that the use of traditional Chinese medicine (TCM) has a positive effect on the treatment of hypoglycemia. Here the authors reviewed the current understanding of sensing and counterregulatory responses to hypoglycemia, and discuss combining traditional Chinese and Western medicine and the theory of iatrogenic hypoglycemia in diabetes treatment. Furthermore, the authors clarify the feasibility of treating hypoglycemia on the basis of TCM theory and CNS and have an insight on its clinical practice.

OBJECTIVE:To establish a reasonable return level for Chinese pharmaceutical industry and to study the return level of the domestic pharmaceutical industry from 2000 to 2005.METHODS:In view of the financial data of Chinese pharmaceutical industry in the statistical yearbook from 2001 to 2006,the return level for Chinese pharmaceutical industry was established based on its risk level using the principle of "risk-return equilibrium",and the rationality of the return level of Chinese pharmaceutical industry over the 6 years was validated as well.RESULTS:Over the 6 years,the average lowest anticipating rate of return for the Chinese medicine industry was 7.72% and the actually average assets income rate stood at 8.53%,i.e.the average abnormal return rate over the 6 years was 0.81%.CONCLUSION:The return rate of Chinese pharmaceutical industry corresponds to the risk level as well as the reasonable return level.

OBJECTIVE:To probe into the profits level and profits-gaining capability of Chinese pharmaceutical industry.METHODS:Based on the data recorded in yearbooks between 2001 and 2006,the profits levels were compared between Chinese pharmaceutical industry and China social average assets,other industries in China and overseas pharmaceutical industry.RESULTS:Between 2000～ 2005,the profits level of Chinese pharmaceutical industry was lower than that of Chinese social average assets,i.e.the profit-gaining capability of Chinese pharmaceutical industry was lower than that of China social average assets.Between 2002～ 2004,the profits level of Chinese pharmaceutical industry ranked at the first 10 places among the 39 industries,but dropped far behind in 2005,meanwhile the number of pharmaceutical enterprises who suffered loss increased greatly.CONCLUSION:The prospect for the development of Chinese pharmaceutical industry and the industry environment they confronted are far from optimistic.

Objective To explore the relationship between serum miRNA-21 and miR-27b levels and prognosis of patients with renal clear cell carcinoma.Methods A total of 118 patients with renal clear cell carcinoma admitted to the Qinghai University Hospital from February 2019 to April 2021 were selected as the study subjects,and another 118 healthy patients in the same period as the control group.Real time fluorescence quantitative polymerase chain reaction(PCR)was used to detect the expression of miR-21 and miR-27b in the serum of all subjects.The relative expression levels of serum miR-21 and miR-27b between the patients with renal clear cell carcinoma and healthy control patients were compared.The expression and correlation of serum miR-21 and miR-27b in the patients with renal clear cell carcinoma of different pathological stages and Fuhrman grading were analyzed.The relationship between the expression of serum miR-21 and miR-27b and the survival and prognosis of the patients was explored as well.Results The expression levels of serum miR-21 and miR-27b in the patients with renal clear cell carcinoma were higher than those in the healthy control group(P＜0.05).The serum miR-21 expression level in stage Ⅲ patients was higher than in stageⅠ(P＜0.05),while the serum miR-21 expression level in the stage Ⅳ patients was higher than that in stagesⅠ,Ⅱ,and Ⅲ(P＜0.05).The expression level of miR-27b in the serum of patients gradually increased across the four stages,with a significant difference(P＜0.05).The pathological staging was positively correlated with the expression of miR-21 and miR-27b(P＜0.001).The expression levels of miR-21 and miR-27b in serum of patients gradually increased across grades Ⅰ,Ⅱ and Ⅲ by Fuhrman grading,with significant difference(P＜0.05).Fuhrman grading was positively correlated with the serum miR-21 and miR-27b expression(P＜0.001).There was a statistically significant difference in the survival curve between the miR-21 high expression group and the low expression group(P＜0.05).There was a statistically significant difference in the survival curve between the high expression group and the low expression group of miR-27b(P＜0.05).Conclusion The expression levels of serum miR-21 and miR-27b in patients with renal clear cell carcinoma is indicative of the progression and prognosis of the patient's condition.

This paper reports a pair of siblings with congenital short-bowel syndrome (CSBS) complicated with intestinal malrotation. Case 1 was born with a birth weight of 2 550 g and a length of 48 cm. On September 10, 2017, emergency Ladd's procedure and appendectomy were performed on the infant 23 days after birth due to intestinal obstruction at the Women and Children's Hospital, School of Medicine, Xiamen University. The small intestine of the infant had a total length of 65 cm. Postoperative enteral and parenteral nutrition supports were provided for six months. Whole exome sequencing revealed a homozygous variant (NM 024769; nucleotide deletion in the exon 3-5) in the CLMP gene (chr11:122953792-122955421), with the parents being the heterozygous carriers but without phenotype. Case 2, the younger sibling of Case 1, was born in the same hospital on March 20, 2020, with a birth weight of 2 932 g and a body length of 49 cm. Prenatal single-gene sequencing on the amniotic fluid identified the same gene variation as his sister's. The baby boy received Ladd's procedure and appendectomy on the second day after birth which found the length of his small intestine was 51 cm. Full enteral nutrition was achieved six months after the operation. Both cases were followed up for 12 months. The body weight and length of Case 1 were both below the first percentile (< P1). The body weight of Case 2 was 8.03 kg ( P3- P5) and the length was 76.0 cm ( P25- P50).

Objective:To evaluate the effect of miR-216a-5p on the radiosensitivity of liver cancer cells via targeting Krüppel-like transcription factors 12 (KLF12).Methods:Real-time reverse transcription PCR (RT-qPCR) was used to detect miR-216a-5p, KLF12 mRNA levels in normal human liver cells L-02 cells, and human hepatoma cells Huh7, HepG2, Hep3B and MHCC-97H cell lines. HepG2 cells were divided into 0, 2, 4, 6 and 8 Gy irradiation groups, and miR-216a-5p, KLF12 mRNA levels were compared among different groups. HepG2 cells overexpressing miR-216a-5p and / or KLF12 were constructed by plasmid transfection and divided into the miR-NC group (control group), miR-216a-5p group, miR-216a-5p+NC group, miR-216a-5p+KLF12 group, IR+miR-NC group, IR+miR-216a-5p group, IR+miR-216a-5p+NC group, IR+miR-216a-5p+KLF12 group, respectively. miR-216a-5p, KLF12 mRNA levels were compared among different groups. Clone formation assay was used to detect cell radiosensitivity. CCK-8 assay was employed to detect cell proliferation ability. Flow cytometry was adopted to detect cell apoptosis. Single factor ANOVA was used for inter group comparisons. LSD- t test was used for pairwise comparison. Results:Compared with L-02 cells, KLF12 mRNA levels were up-regulated, whereas miR-216a-5p levels were down-regulated in liver cancer cell lines (all P<0.05). Compared with 0 Gy group, KLF12 mRNA levels were down-regulated, whereas miR-216a-5p levels were up-regulated in 2, 4, 6, and 8 Gy groups (all P<0.05). Overexpression of miR-216a-5p or radiation therapy alone could enhance cell radiosensitivity and apoptosis levels, and reduce cell proliferation ability (all P<0.05). Simultaneous radiation treatment with overexpression of miR-216a-5p exerted more significant effects on cells (all P<0.05). Overexpression of KLF12 could partially reverse the aforementioned effects of overexpression of miR-216a-5p ( P<0.05). Conclusion:MiR-216a-5p reduces cell proliferation ability, enhances cell radiosensitivity and apoptosis via regulating KLF12.

Objective:To describe and analyze suicide risk of patients with schizophrenia,major depressive disorder,and bipolar disorder.Methods:A total of 2 016 patients with schizophrenia,903 patients with major de-pressive disorder,and 381 patients with bipolar disorder from inpatients,clinics,or communities who met the diag-nostic criteria of the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition were recruited.All patients were interviewed by psychiatrists using the Mini International Neuropsychiatric Interview to diagnose mental disor-ders and assess suicide risk,as well as Clinical-Rated Dimensions of Psychosis Symptom Severity(CRDPSS)to as-sess symptoms.Differences and risk factors of suicide risk among three types of mental disorders were explored u-sing multivariate logistic regression analysis.Results:In the past one month,37 patients with schizophrenia(1.8％),516 patients with major depressive disorder(57.1％),and 102 patients with bipolar disorder(26.8％)had suicide risk.Compared with patients with schizophrenia,suicide risk in patients with major depressive disorder(OR=36.50)and bipolar disorder(OR=20.10)increased.Female(OR=1.87),smoking(OR=1.76),family history of suicide(OR=5.09),higher score of CRDPSS hallucination(OR=1.80),and higher score of CRDPSS depression(OR=1.54)were risk factors of suicide risk of patients.Conclusions:Suicide risk of patients with ma-jor depressive disorder and bipolar disorder is higher than that of patients with schizophrenia.In clinical practice,it is important to regularly assess suicide risk of patients.Patients who experience symptoms of hallucination and de-pression should be paid more attention to.
