OBJECTIVETo evaluate the effect of lateral supramalleolar artery descending branch antidromic flap for the repair of soft tissue defects in the foot and ankle.
METHODSFrom May 2009 to October 2013,12 patients with soft tissue defects combined with tendon and bone exposure in the foot and ankle were treated by lateral supramalleolar artery descending branch antidromic flap for the repair of soft tissue defects in the foot and ankle, including 9 males and 3 females with an average age of 37.5 years old ranging from 19 to 58 years. Ten cases had the soft tissue defects in the dorsum of foot and 2 in the ankle. The defect area of soft tissue was from 11 cm x 9 cm to 8 cm x 5 cm.
RESULTSTwelve patients were follow-up for 3 to 12 months (averaged 7.3 months). The flaps of 9 cases were survived,the flaps edges of the other 3 cases were necrosis,and healed after dressing change. The flaps were slightly swelling without ulcer occurrence.
CONCLUSIONLateral supramalleolar artery descending branch antidromic flap can repairing the damage by one-stage operation with advantage of dissection easy,rich blood supply without sacrifice of major artery.

Objective To analyze the optimal scales of secondary public hospitals so as to optimize the expansion of public hospitals.Methods Forty-six secondary public general hospitals in Beijing were selected as the sample,with input and output indicators pinpointed,for analysis of the status of economic return to scale of such hospitals from 1996 to 2012,and identification of inflexion points of the returns to scale.These efforts will help find an optimal scale of such hospitals.Resalts The period from 1996 to 2012 found the general effectiveness of such hospitals in a decline.In 2012,only 4 of the 46 hospitals were in DEA effectiveness status,and the other 42 hospitals were not; Forty-three inflexion points were identified.This study found that the strict control standards for secondary public general hospitals in Beijing were 298 beds and 585 staffs; the flexible control standards were 421 beds and 807 staffs.Conclclsion The optimal scales for secondary public hospitals were drown from the analysis,for references of other regions in China.The hospitals should prioritize resources efficiency instead of scale expansion.

Objective To analyze the effect of quality of life (QOL) on the prognosis of long-term survivors with nasopharyngeal carcinoma (NPC). Methods A total of 192 NPC patients treated between 1999 and 2000 and with tumor-free survival before July 2003 were enrolled in this study. All patients received QOL measurement between July and August in 2003. Measurement scales included Chinese SF-36 questionnaire and a checklist consisting of fourteen items about self-rating symptoms. The median follow-up time was 7.9S years (range 2.67-9.55 years). The effects of QOL, social demographic and clinical factors on prognosis were analyzed. Results Univariate analysis showed that QOL affected the tumor-free survival and overall survival. Multivariate analysis showed that hypomnesia was an independent prognostic factor of tumor-free survival, while trismus, headache and age were independent prognostic factors of overall survival. The younger and the better QOL had better prognosis. The other sociodemographic and clinical factors had no prognostic value. Conclusion QOL is an important factor affecting the prognosis of long-term survivors with NPC, and it should be routinely evaluated during the follow-up.

OBJECTIVETo explore the relationship between the insertion/deletion (I/D) polymorphism of angiotensin converting enzyme (ACE), and blood stasis syndrome (BSS) in patients with coronary heart disease (CHD).
METHODSThe ACE gene type in 48 patients of CHD of BSS type, 52 CHD patients of non-BSS type and 54 healthy subjects (control) was determined by PCR assay, also levels of endothelin (ET), angiotensin II (Ag II), and nitric oxide (NO) were determined.
RESULTSOccurrence of DD genotype and allele genotype of ACE gene was higher in patients of BSS than that in patients of non-BSS and control (P < 0.01). ET/NO level was higher in patients of BSS than that in control (P < 0.01). ET and Ag II levels in patients of BSS were significantly higher than those in patients of non-BSS (P < 0.05) and control (P < 0.01). Levels of ET/NO and Ag II in subjects with DD genotype in various groups were higher than those in subjects with Ag II or ID genotype, the highest level occurred in patients of BSS with DD genotype, when compared with the other two groups, the difference in Ag II was significant (P < 0.05 and P < 0.01), when compared with control, the difference in ET/NO was significant (P < 0.01).
CONCLUSIONDD genotype of ACE gene may be the susceptible gene of CHD in patients of BSS type.

OBJECTIVETo carry out genotype analysis of enterovirus type 71, detected from hand-foot-mouth disease patients in Shenzhen in 2004.
METHODSAll samples were tested by reverse transcription-polymerase chain reaction (RT-PCR) using EV71 specific primer. The VP1 and VP4 of EV71 were cloned and sequenced. A phylogenetic tree was constructed by comparing the sequences with genogroups A, B and C genotypes using TreeView and PHYLIP software (3.6b).
RESULTSThe VP1 nucleotide sequence of 4 strains isolated from Shenzhen shared 87.8% - 92.0% identity with genogroup C, while the homogeneity of the VP4 nucleotide sequence was between 85.9% - 87.4%. The homogeneity of the VP1 nucleotide sequence with genotypes A and B was between 81.9% - 84.2% and was 80.6% - 85.0% with VP4. Among the 4 strains, the homogeneity of the VP1 nucleotide sequence was between 94.1% - 99.8% and was 100% with VP4 which formed a small group and could denominate EV71 genetype C4.
CONCLUSIONSimilar results were obtained from phylogenetic analysis of EV71 based on VP1 and VP4 nucleotide sequence. The four EV71 strains causing epidemic in Shenzhen could be named as C4 subgroups.

Intestinal fibrosis associated stricture is a common complication of inflammatory bowel disease usually requiring endoscopic or surgical intervention. Effective anti-fibrotic agents aiming to control or reverse intestinal fibrosis are still unavailable. Thus, clarifying the mechanism underpinning intestinal fibrosis is imperative. Fibrosis is characterized by an excessive accumulation of extracellular matrix (ECM) proteins at the injured sites. Multiple cellular types are implicated in fibrosis development. Among these cells, mesenchymal cells are major compartments that are activated and then enhance the production of ECM. Additionally, immune cells contribute to the persistent activation of mesenchymal cells and perpetuation of inflammation. Molecules are messengers of crosstalk between these cellular compartments. Although inflammation is necessary for fibrosis development, purely controlling intestinal inflammation cannot halt the development of fibrosis, suggesting that chronic inflammation is not the unique contributor to fibrogenesis. Several inflammation-independent mechanisms including gut microbiota, creeping fat, ECM interaction, and metabolic reprogramming are involved in the pathogenesis of fibrosis. In the past decades, substantial progress has been made in elucidating the cellular and molecular mechanisms of intestinal fibrosis. Here, we summarized new discoveries and advances of cellular components and major molecular mediators that are associated with intestinal fibrosis, aiming to provide a basis for exploring effective anti-fibrotic therapies in this field.

OBJECTIVETo study the expression of peptidyl-prolyl cis/trans isomerase (PPIase or Pin1) in malignant hematopoietic cells and its relation with cell cycle.
METHODSRealtime quantitative PCR with fluorescence probe hybridization was used to measure expression of Pin1 mRNA in malignant hematopoietic cell lines and normal mononuclear cells separated from bone marrow. HeLa cells were blocked with Thymidine and Nocodazole in different cell phases and then the expression of Pin1 mRNA and protein were detected by realtime-PCR and immunoblotting.
RESULTSThe expression of Pin1 in malignant hematopoietic cell lines was significantly higher than that in normal controls (0.339 +/-0.093 compared with 0.038 +/-0.005, P<0.01). Its expression in myeloid malignant hematopoietic cell lines was significantly higher than that in normal controls (0.388 +/-0.115 compared with 0.038 +/-0.005, P<0.01) and so was the malignant lymphocytic cell lines (0.226 +/-0.166 compared with 0.038 +/-0.005, P<0.01). The expression of Pin1 was closely correlated with cell cycle. It was the highest in G1 phase and the lowest in S phase (110.762 +/-16.737 compared with 4.080 +/-0.634, P<0.01).
CONCLUSIONPin1 is overexpressed in malignant hematopoietic cell lines and its expression is different during cell cycle that is highest in G1 phase and lowest in S phase.
