The main purposes of translational Medicine is to break the barrier among the basic medicine,clinical medicine and drug R&D in order to establish direct and close connection and cooperation between them.However,so far almost in the world wide,translational medicine is still at the exploration stage and far away from the real transformation.This article reviewed the difficult position of translational medicine cooperation from the three aspects of cooperative resources,sponsor and domestic culture,and then suggested to promote clinical medicine research,set up new assessment systems which focus on classified evaluation and representative work,as well as create the culture of cooperation.

Objective To intensify clinical evaluation on the manifestation, diagnosis and treatment of primary malignant duodenal tumors. Method The clinical data of 81 patients with primary malignant duodenal tumors from 1990 to 2002 were analyzed retrospectively. Result Tumors located above, around and below the duodenal papilla accounted for 16%, 78%, 6% respectively. The common clinical presentations were weight loss(72%)?abdominal pain(64%)?jaundice(45%)?alimentary tract bleeding(40%)?vomiting(33%) and anemia(24%). The preoperative diagnosis rate was 80%. Pancreatoduodenectomy was performed in 54 cases, bypass operation in 21 cases, segmental duodenectomy and simple laparotomy in 2 cases each. The postoperative 3- and 5- year survival rate was 36% and 21% for patients undergoing curative resection. In those with bypass operation, the survival time was between 1～18 months. Two cases undergoing segmental duodenectomy died within one year. Conclusion Patients usually lack special symptoms and signs, early diagnosis is fairly difficult, pancreaticoduodenectomy performed for purpose of curative resection could improve the prognosis of this malignancy.

Objective:To explore the correlation among psychological flexibility, pain stimulation and adaptation of patients with chronic pain.Methods:From July to September 2020, convenience sampling was used to select 491 patients admitted to the Department of Orthopedics in 5 Class Ⅲ Grade A hospitals in Beijing and Shanghai. The survey was conducted with the self-designed General Information Questionnaire, Psychological Inflexibility in Pain Scale (PIPS) , Pain Disability Index (PDI) , Tampa Scale of Kinesiophobia (TSK-11) and the Chinese version of World Health Organization Quality of Life-BREF (WHOQOL-BRIF) , and the structural equation model hypothesis was proposed.Results:Among patients with chronic pain, the total PIPS score, PDI score, and the total TSK-11 score were (51.06±14.35) , (31.41±18.31) and (30.42±6.43) respectively. The scores of physical health, psychological health, social relationships, environment, overall quality of life and general health were (12.55±2.19) , (13.04±2.42) , (14.29±2.97) , (12.98±2.79) , (3.17±0.98) and (2.73±0.99) respectively. Painful stimulation could produce exercise fear ( β=3.382, t=21.754, P<0.05) , and exercise fear affected stereotype psychology ( β=3.382, t=21.754, P<0.05) , and stereotype psychology had a direct negative impact on the quality of life ( β=-0.092, t=-6.516, P<0.05) . Conclusions:The pain stimulus of patients with chronic pain affects the patient's psychological flexibility through exercise fear, thereby further affecting the patient's quality of life.

Objective:To explore the role of Mycoplasma pneumoniae (MP) in hospitalized children with community-acquired pneumonia (CAP) in Suzhou.Methods:Pathogen data of 2 367 patients with bronchiolitis, bronchopneumonia, lobar pneumonia, and interstitial pneumonia were retrospectively analyzed from January 2017 to December 2018 in Children′s Hospital of Soochow University. The detected pathogens were MP, respiratory syncytial virus (RSV), adenovirus (Adv), influenza A, B, parainfluenza virus (PIV) 1, 2 and 3, human metapneumovirus (hMPV), boca virus (HBoV) and bacteria.Results:The most common pathogen of bronchiolitis was RSV (34.9%, 249/713), followed by MP (15.8%, 113/713) and hMPV (11.4%, 85/713). The most common pathogen of bronchial pneumonia was Streptococcus pneumoniae (Sp, 14.8%, 180/1 220), followed by RSV (13.1%, 160/1 220) and MP (10.2%, 124/1 220). The most common pathogen of lobar pneumonia was MP (47.8%, 141/295), followed by Sp(12.9%, 38/295). The most common pathogen of interstitial pneumonia was MP (35.3%, 49/139), followed by RSV (23.0%, 32/139) and Adv (6.5%, 9/139). Compared with non-MP infections, children with MP infections were older, and had higher percentage of fever and less shortness of breath. The adjusted OR(95% CI) was 2.4 (1.1-3.5), 5.1 (3.2-10.4) and 0.2 (0.0-0.4), respectively. Conclusions:MP is the most common pathogen of lobar pneumonia and interstitial pneumonia and the second most common cause of bronchiolitis. MP infections are usually associated with older age, higher percentage of fever and less shortness of breath.

Objective To explore the clinical efficacy and safety of betaquiline fumarate tablets in the treatment of multi drug resistant pulmonary tuberculosis.Methods Patients with multidrug-resistant tuberculosis(MDR-TB)admitted to the Third People's Hospital of Kunming from March 2019 to September 2022 were selected as the research objects.They were divided into two groups by random number table method.The observation group(n = 93)received anti tuberculosis treatment with a regimen containing bedaquiline fumarate tablets,while the control group(n = 90)received anti tuberculosis treatment with a regimen without bedaquiline fumarate tablets.The lesion absorption rate,sputum negative conversion rate,cavity reduction rate,treatment efficiency,and adverse drug reactions during treatment were collected at the end of 24 weeks.Results At the end of the 24th week of treatment,the differences between the observation group and the control group in the rates of lesion absorption rate(85.7%,63.3%),negative conversion of sputum smears(89.7%,71.4%),negative conversion of sputum cultures(82.1%,68.6%),cavity shrinkage rate(88.2%,69.4%),and total treatment efficacy(81.9%,60.2%)were statistically significant(P<0.05).The difference in the incidence of adverse drug reactions between the observation group and the control group(69.9%and 83.4%)was statistically significant(P<0.05),but the difference in the severity of adverse reactions was not statistically significant(P>0.05).Conclusion The regimen containing betaquiline fumarate tablets has good efficacy and is safe in the treatment of multidrug-resistant pulmonary tuberculosis.

Objective To investigate the mechanism of Guizhi Tongluo Tablets(GZTLP)on improving atherosclerosis in APOE knockout mice by regulating neutrophil extracellular trapping nets(NETs).Methods After modeling,24 APOE knockout mice aged 8 weeks were randomly divided into 4 groups:GZTLP high-dose group,low-dose group,model control group and normal control group,with 6 mice in each group.GZTLP was given 1.87 mg·g-1 and 0.47 mg·g-1 intragastric administration in high-dose group and low-dose group,respectively.The normal control group and model control group were given 0.9%sodium chloride solution intragastric administration for 6 weeks,and the lipid plaque deposition in aorta was observed by gross oil red O staining.Lipid deposition in aortic root was observed by oil red O staining.The pathological changes of lipid plaques in aortic root were observed by HE staining.The levels of interleukin-1β(IL-1β)and tumor necrosis factor α(TNF-α)in peripheral blood of mice were detected by enzyme-linked immunosorbent assay(ELISA).The expression of lymphocyte antigen 6G(Ly6G),myeloperoxidase(MPO)and citrulinated histone(Cit-H3)in plaques of the aortic arch and the colocalization of Ly6G,MPO and Cit-H3 were detected by immunofluorescence assay.Results Compared with the normal control group,the aorta of mice in the model control group showed serious lipid plaque deposition,morphological damage,and a large number of inflammatory cells infiltration,the contents of serum inflammatory factors IL-1β and TNF-α were increased,and the protein expressions of Ly6G,Cit-H3 and MPO were significantly increased.Compared with model control group,GZTLP group reduced the amount of lipid plaque deposition in aorta,the arrangement of aortic cells was more regular,the inflammatory cell infiltration was improved,and the contents of serum inflammatory factors IL-1β and TNF-α were significantly decreased(P<0.05).The colocalization and the protein expression of Ly6G,MPO and Cit-H3 were significantly decreased in aortic tissues(P<0.01).Conclusions GZTLP can improve atherosclerosis,and its mechanism may be related to the inhibition of neutrophil extracellular trapping nets.
