Alzheimer's disease(AD),which is one type of senile deimentia, has three remarkable pathologic characteristics-senile plaque,neurofibrillar tangles and neuronal death. As a neurotrophic factor, basic fibroblast growth factor(bFGF)is closely related to AD. This article reviewed the interaction between bFGF and AD-associated gene products(such as amyliod ? protein,presenilin, apoloprotein E and microtubulin associated protein tau)and neuronal apoptosis. Some researchers suggested that bFGF may be put forward as potential therapeutic agent in AD and play a role in preventing or retarding the pathological process of this disease, alleviating or even eradicating the pathological insults of this disease.

Objective To discuss the therapy modalities and their efficacy for Cobb's syndrome Methods Data from 14 cases of Cobb's syndrome were retrospectively reviewed of which diagnosis, management and follow-up were discussend. Results Follow-up period of the 14 cases was 4 months to 3 years, of them, no complete cure occurred, 12 cases improved, 2 cases deteriorated. Conclusions Early diagnosis and early treatment using in terventional and surgical method are the key point for this kind of in curable diseases.

This study was aimed to find the relationship between lung function injured characteristic of ulcerative colitis (UC) and endoscopic index. It will verify and enrich Chinese medicine theory to guide clinical diagnosis and treatment. UC patients without respiratory system diseases were selected between September 2009 and March 2011 from several triple-A hospitals in China. Furthermore, disease history, lung function, colonoscopy and histopathology were taken. The results showed that among 171 enrolled cases, there were statistical differences in endoscopic index of residual-function and diffusion-function between the abnormal group and the normal group (P< 0.05). The resid-ual-function group was r = 0.003. There were no statistical differences in ventilatory-function and small-airway-function in the abnormal group. It was concluded that there were different types of injured lung function in UC. A-mong them, the abnormalities of residual-function and diffusion-function had strong correlation with the intestinal damage degree. The change on residual-function was more obvious.

OBJECTIVETo analyze clinical manifestations and genetic mutation in a child with severe short stature and other malformations.

METHODSThe child has undergone history taking and physical examination. Genome DNA was extracted from peripheral blood samples of the proband and her family members. Candidate genes were captured with Agilent SureSelect and sequenced on an Illumina platform. Suspected mutation was verified by Sanger sequencing.

RESULTSThe patient, a six-year-and-10-month old girl, presented with non-symmetrical short stature, dysmorphism, abnormalities of limbs and spine, amblyopia of left eye, and cataract of right eye, in addition with frequent respiratory infection and micturition. Laboratory testing suggested 25-hydroxy vitamin D deficiency (18.9 ng/mL). Spine X-ray showed multiple malformations with centrums. Her mother also featured short stature (138 cm). Her aunt had short stature (130 cm) and limb-length discrepancy. Her little brother was 2.5 years old, and his height was 81 cm (-3.4 SD). Exome sequencing revealed a heterozygous mutation c.184C to T (p.Arg62Trp) in the proband and her mother. The same mutation was not found in her father and brother.

CONCLUSIONThe patient was diagnosed with X-linked chondrodysplasia punctata 2. Mutation of the EBP gene probably underlied the disease in this family.

Objective To analyze the incidence and risk factors of de novo malignant tumors in renal transplant recipients. Methods Clinical data of 1 549 renal transplant recipients were retrospectively analyzed, including the basic status, pathological type and incidence rate of patients with de novo malignant tumors after renal transplantation. The survival situation of these patiensts was assessed. And the risk factors of de novo malignant tumors after renal transplantation were identified. Results The incidence rate of de novo malignant tumors in renal transplant recipients was 3.03%(47/1 549). The 47 recipients were (48±12) years old when undergoing renal transplantation, and they were (55±12) years old when diagnosed malignant tumors. The time interval between transplantation and diagnosis was 66 (36, 100) months. Among the de novo malignant tumors, colorectal cancer was the most common, with a cumulative incidence rate (CIR) of 0.58%. The survival time of 47 recipients with de novo malignant tumors after renal transplantation was 59 (2, 135) months, and the 5-year survival rate was 50%. The recipients with the age > 45 years old when undergoing renal transplantation was a risk factor for de novo malignant tumors after renal transplantation (P < 0.05). Conclusions The incidence rate of de novo malignant tumors is relatively high in renal transplant recipients. The recipients with the age > 45 years old when undergoing renal transplantation is a risk factor for de novo malignant tumors.

The twenty-first century has already recorded more than ten major epidemics or pandemics of viral disease, including the devastating COVID-19. Novel effective antivirals with broad-spectrum coverage are urgently needed. Herein, we reported a novel broad-spectrum antiviral compound PAC5. Oral administration of PAC5 eliminated HBV cccDNA and reduced the large antigen load in distinct mouse models of HBV infection. Strikingly, oral administration of PAC5 in a hamster model of SARS-CoV-2 omicron (BA.1) infection significantly decreases viral loads and attenuates lung inflammation. Mechanistically, PAC5 binds to a pocket near Asp49 in the RNA recognition motif of hnRNPA2B1. PAC5-bound hnRNPA2B1 is extensively activated and translocated to the cytoplasm where it initiates the TBK1-IRF3 pathway, leading to the production of type I IFNs with antiviral activity. Our results indicate that PAC5 is a novel small-molecule agonist of hnRNPA2B1, which may have a role in dealing with emerging infectious diseases now and in the future.
