Objective To investigate the effect of fimH gene on type 1 fimbriae adhesion of uropathogenic Escherichia coli (UPEC) and the gene variations between type 1 fimbriae adhesion positive and negative bacteria.Methods A total of 171 UPEC strains (not catheter associated) were collected from the Second Hospital of Tianjin Medical University,Tianjin First Center Hospital,and Tianjin Children's Hospital during January 2012 and January 2013.fimH gene was detected by PCR technique,and type 1 fimbriae adhesion was detected by yeast agglutination test.RT-PCR was used to exterminate gene transcript factor impacting on adhesion.Chi-square and Yates' chi-squared tests were performed to comparefimH gene sequences between the adhesion positive and negative bacteria.Results Among 171 UPEC strains,142 (83％) werefimH gene positive,and type 1 fimbriae was expressed in 98 strains (57％).All adhesion positive strains carriedfimH gene.Among 44 strains with positivefimH gene and negative adhesion RT-PCR revealed thatfimH gene did not transcript in 8 strains (18％).The sequencing results showed that gene mutation on the 51 st amino acid site was more prevalent in the adhesion positive group compared with the negative group (x2 =6.64,P =0.010).In adhesion,mutations on the 190th and 219th amino acid sites were observed in 6 strains and 7 strains of negative group,respectively; while not observed in the adhesion positive group (x2 =4.69 and 5.87,P ＜ 0.05).Negative adhesion in other 23 strains was not attributed to single nucleotide polymorphism.Conclusion Adhesion function of type 1 fimbriae mignt be affected by mutation and deletion offimH gene.Three key site mutations may also affect the adhesion function of type 1 fimbriae.Besides fimH gene,there may be other genes that can affect the adhesion function of type 1 fimbriae.

A device for promoting normal locomotor activity recuperation was made, which was composed by frame, elastic bolt and normal gait mark carpet. The device has the effects of weight relieving, abnormal gait preventing, and safeguards providing. The patient could do gait training by he/her self or assistant self training under the weight reducing and protecting of the device in order to improve the walking ability and the normal gait formation. It is effective for preventing drop foot and leg adduction, and also helpful for the recovery of normal gait ability and the prevention of abnormal gait formation. It is applicable for the patient who can not be trained with ordinary weight relief walking training, such as severe cerebral palsy and severe spasmodic lower extremity and foot drop after brain injury. The results demonstrated that the device is effective in protecting, correcting, preventing abnormal gait as well as forming normal gait.

To make a portable apparatus for the patient self-doing joint voluntarily exercise that is keeping with the training demand of human body potential and muscle strong. Different kinds of spring belts are used for joint exercise apparatus according to the needs of joint exercise. Though active joint extension and flexion by using the method of Chinese physical and breathing exercises, the exercise was done by drawing the spring belt. The extremity multifunctional training box is easy for carrying and sutble for each mussel be trained. Because of the wide range of back spring power, it is easy to reach the best training mount and to do the continually training under the biggest training mount. It is beneficial to the joint active function improvement. From June 2006 to February 2008, this kind of apparatus was used in 30 patients with footdrop at the Beijing Tongren Hospital, Capital Medical University. The design of the extremity multifunctional training box is reasonable, and it is easy for carrying and operating. It is also helpful for the patient to do muscle exercise themselves, and the joint function can be persisted and improved by continual exercise using this apparatus.

The purpose of this study is to evaluate the effect of oligomeric grape seed proanthocyanidins (GSP) on isoproterenol (ISO)-induced cardiac remodeling in rats. ISO was given subcutaneously (5 mg x kg(-1), sc, 7 days) to induce cardiac remodeling in rats. Therapeutic groups were given GSP (50, 100, and 150 mg x kg(-1)) after ISO treatment. After 2 weeks intervention, heart rate (HR), left ventricular systolic pressure (LVSP), left ventricular end-diastolic pressure (LVEDP), rate of rise of left ventricular pressure (+/- dp/dt(max)) were examined. The myocardial hypertrophy index was expressed as heart weight/body weight (HW/BW) and left ventricle weight/body weight (LVW/BW), the histological changes were investigated by HE and Van Gieson stain. SOD activity and MDA content in serum, contents of hydroxyproline (Hyp) in the left ventricular tissue were assayed by xanthinoxidase method, thiobarbituric acid (TBA) method and alkaline hydrolysis method, respectively. After the onset of ISO-treatment, GSP therapy potently improved cardiac function, inhibited myocardial hypertrophy, improved cardiac pathology change, decreased the myocardial cross-section area (CSA), collagen volume fraction (CVF) and perivascular circumferential collagen area (PVCA), reduced the content of Hyp in the left ventricular tissue, inhibited the decrease of SOD activity and increase of MDA content in serum. GSP possess protective effect against ISO induced cardiac remodeling in rats, this may be related to reducing the oxidative stress and improving antioxidant capacity.

Objective: To investigate the incidence and clinical characteristics of urothelial carcinoma (UC) accompanied with multiple primary carcinoma (MPC). Methods: The clinical data of 121 UC patients with MPC in Peking University Third Hospital from January 2010 to May 2018 were retrospectly analyzed. Results: UC patients with MPC accounted for 9.74% (121/1 242) of all the UC patients. The ratio of male to female patients was 2.10∶1 in the total MPC patients, but it was 1∶1 in the upper urinary tract MPC subgroup. The MPC patients were more common in elderly people, whose medium age was 68 (32-93) years old. Of all the location (131 person-time) of other tumors besides UC, the digestive system tumors occurred most frequently, accounting for 41.98% (55/131), followed by the urinary and male reproductive system tumors (20.61%, 27/131) and the female reproductive system (12.21%, 16/131). The proportion of the digestive system tumors (47.37%, 9/19) was the highest in the upper urinary tract MPC, with a total number of the other primary cancer of 19 person-time. However, the proportion of the urinary and male reproductive system tumors (37.14%, 13/35) was higher in the synchronous MPC group, with a total number of the other primary cancer of 35 person-time. Some patients had a history of radiotherapy and/or chemotherapy before UC was diagnosed. We also observed 2 cases of genetically confirmed Lynch syndrome. The median overall survival (mOS) of UC patients with MPC was 132 months, and the mOS of patients with UC as the first malignancy (including synchronous MPC and UC as the first malignancy in metachronous MPC) was 120 months. The mOS of the synchronous MPC group was 84 months, which was significantly shorter than 178 months of metachronous MPC group (χ² =14.029, P<0.001). Conclusions The incidence of UC accompanied with MPC is not low, and the most common sites of MPC are the digestive system and reproductive system. Therefore, screening for MPC in UC patients, especially those with personal or family history of tumors, as well as elderly patients, may help early diagnosis and treatment of MPC patients and improve their prognoses.

Beijing has been one of the epicenters attacked most severely by the SARS-CoV (severe acute respiratory syndrome-associated coronavirus) since the first patient was diagnosed in one of the city's hospitals. We now report complete genome sequences of the BJ Group, including four isolates (Isolates BJ01, BJ02, BJ03, and BJ04) of the SARS-CoV. It is remarkable that all members of the BJ Group share a common haplotype, consisting of seven loci that differentiate the group from other isolates published to date. Among 42 substitutions uniquely identified from the BJ group, 32 are non-synonymous changes at the amino acid level. Rooted phylogenetic trees, proposed on the basis of haplotypes and other sequence variations of SARS-CoV isolates from Canada, USA, Singapore, and China, gave rise to different paradigms but positioned the BJ Group, together with the newly discovered GD01 (GD-Ins29) in the same clade, followed by the H-U Group (from Hong Kong to USA) and the H-T Group (from Hong Kong to Toronto), leaving the SP Group (Singapore) more distant. This result appears to suggest a possible transmission path from Guangdong to Beijing/Hong Kong, then to other countries and regions.

We report a complete genomic sequence of rare isolates (minor genotype) of the SARS-CoV from SARS patients in Guangdong, China, where the first few cases emerged. The most striking discovery from the isolate is an extra 29-nucleotide sequence located at the nucleotide positions between 27,863 and 27,864 (referred to the complete sequence of BJ01) within an overlapped region composed of BGI-PUP5 (BGI-postulated uncharacterized protein 5) and BGI-PUP6 upstream of the N (nucleocapsid) protein. The discovery of this minor genotype, GD-Ins29, suggests a significant genetic event and differentiates it from the previously reported genotype, the dominant form among all sequenced SARS-CoV isolates. A 17-nt segment of this extra sequence is identical to a segment of the same size in two human mRNA sequences that may interfere with viral replication and transcription in the cytosol of the infected cells. It provides a new avenue for the exploration of the virus-host interaction in viral evolution, host pathogenesis, and vaccine development.

Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.
