AIM To observe the effects of Guhoukang Granules (Eucommiae Cortex,Dipsaci Radix,Corni Fructus,etc.) on bone metabolism indexes of the geriatric femoral intertrochanteric fracture.METHODS A total of eighty patients meeting the inclusion criteria,cured with fixed operation of proximal femoral anti-rotation nail and given basic care,were divided randomly and equally into two groups:experiment group (Guhoukang Granules ) and control group (calcium carbonate D3 tablets).Three months made a course.Osteocalcin (OC),calcitonin (CT),bone-specific alkaline phosphatase (BALP),total procollagen type 1 aminoterminal propeptide (tPINP),β isomer of the C-terminal telopeptide of type Ⅰ collagen (β-CTX),and intact parathyroid hormone (iPTH),were examined before and after three months,respectively.RESULTS There were no significant statistical difference in the levels of OC,CT,BALP,tPINP,β-CTX and iPTH before operation in both groups.The levels of OC,CT,BALP,tPINP in the experiment group obviously increased and the levels of β-CTX,iPTH markedly decreased after the operation,and were better than those in the experiment group pre-operation and in the control group after the operation.The control group had no improvement in bone metabolism indexes pre-and post-operation.CONCLUSION Guhoukang Granules can improve bone metabolism of the geriatric femoral intertrochanteric fracture and facilitate the recovery of the fracture.

Objectives To compare the clinical features between rhinovirus and respiratory syncytial virus infection in lower respiratory tract in children. Methods From December 2012 to May 2013, direct immunofluorescence assay was per-formed to test RSV in 1 037 nasal aspirate specimens with LRTIs. RT-PCR method was used to test HRV RNA. The medical re-cords of patients with a positive test of HRV or RSV were reviewed and compared. Results The isolating rate for HRV and RSV was 8.78%(91/1 037) and 17.16%(178/1 037) respectively. The frequency of co-infection of HRV with other virus was 18.68%, higher than that of RSV (7.30%,χ2=7.867, P=0.005). The age distribution had significant difference between children infected with HRV and RSV (Z=5.40, P<0.001). 78.38% patients with HRV infection were younger than 3 years old, and 83.03%patients with RSV infection were younger than 1 year old. Dyspnea, hyoxemia and wheezing were more common in pa-tients with RSV infection. Admission occurred much later in the course of the HRV infection (P<0.01). Leukocytosis, eosinophi-lia, and an elevated total serum IgE were more common in patients with HRV infection (P<0.05). Conclusions HRV is one of the important causes of LRTIs in Suzhou. The susceptible population, clinical presentation and laboratory results of HRV infec-tions are different from that of RSV infections.

OBJECTIVETo investigate the germline mutations of the CHD7 gene and their roles in patients with congenital heart disease (CHD).

METHODSGenomic DNAs extracted from peripheral blood were subjected to screen mutations in CHD7 gene by denaturing high performance liquid chromatography (DHPLC) followed by DNA sequencing of aberrant peaks in 67 CHD patients and 100 healthy control. Case-control study and bioinformatic analysis were utilized to explore the potential functional roles of the variations detected.

RESULTSSeven kinds of single nucleotide substitution were detected in the CHD patients in different introns of the CHD7 gene. Among them, IVS11+ 127A to G and IVS12+ 21T to G were rare variations and the allele frequencies of both were 0.0075; while IVS2+ 34G to A, IVS4+ 39G to A, IVS12-5T to C and IVS16+ 51C to A were the single nucleotide polymorphisms and the allele frequency was 0.2635, 0.2156, 0.1505 and 0.3636 respectively. The frequency of IVS12-5T to C in the CHD group was significantly lower than that in the control group (5.42%versus 9.57%, P< 0.05). The variant of IVS14-35C to G was only detected in patients with CHD. Bioinformatic analysis showed that IVS12-5T to C might increase exon splicing ability comparing with the wild-type sequence.

CONCLUSIONThe CHD7 gene mutation may not be the main reason for sporadic congenital heart disease, whereas the single nucleotide polymorphism of IVS12-5T to C might play a protective role in the onset of this disease.

Objective: To investigate the clinicopathologic features and possible causes of granulomatous lobular mastitis(GLM). Methods: Three hundred cases of GLM were collected from surgical specimens diagnosed at Longhua Hospital, Shanghai University of Traditional Chinese Medicine from January 2015 to November 2017. Morphologic features were reviewed using HE staining. A total of 116 cases were investigated by Gram staining. The expression of CD3, CD20, CD68, IgG, IgG4, CD38 and CD138 was detected by immunohistochemical staining. Results: The age of the patients was 23 to 47 years and the median age was 32 years. All patients were female, 96.7% (290/300) had a history of lactation.There were 143 cases of left breasts, 138 cases of right breast and 19 cases of bilateral breasts. Serum prolactin increased in 39.7%(119/300) patients. Within 15.7%(47/300) of patients were associated with nodular erythema or joint swelling and pain of the lower extremities. Pathological observation showed that lobular-centric suppurative granulomatous inflammation, accompanied by dilatation of intralobular and interlobular ducts. There were 16 cases accompanied with duct ectasia. Immunohistochemistry showed CD3-positive lymphocytes were more than CD20-positive lymphocytes in the peripheral aggregation zone of neutrophils within granulomatous lesions. Gram positive bacteria were found in the lipid vacuoles of the 51.7%(60/116) patients. Conclusions GLM has distinctive histologic features. It may be related to corynebacterium infection, or accompanied by the increase of serum prolactin and erythrocyte sedimentation rate. The age, location and history of the disease are importance in the diagnosis and differential diagnosis.
