OBJECTIVETo compare clinical effects between percutaneous compressing plating (PCCP) and proximal femoral nail antirotation (PFNA) for the treatment of patients with intertrochanteric fracture with risk external wall.

METHODSFrom September 2007 to June 2010, 43 patients with intertrochanteric fracture with risk external wall were treated by PCCP or PFNA according to different kinds of internal fixations. There were 22 cases in PCCP, including 9 males and 13 females with an average age of 68.4 (ranged, 60 to 86) years old, and 13 cases with type A2.2 and 9 cases with type A2.3; while 21 cases in PFNA, including 7 males and 14 females with an average age of 67.7 (ranged, 57 to 93) years old, and 10 cases with type A2.2 and 11 cases with type A2.3. Blood loss, operation time, hospital stay, fracture healing time, complications and Harris score after 1 years' following-up were observed and compared.

RESULTSAll patients were followed up for 12 to 22 (means 18.4) months, and all patients were obtained fracture healing, and recovered walking ability as before injury. There were no significant differences in blood loss, operation time, hospital stay, fracture healing time, complications and Harris score after 1 years' following-up (P>0.05). One case occurred displacement on the top of greater trochanter, and 1 case injuried weakness of hip abduction. One case occurred screw breakage in PCCP, while 1 case occurred hip joint pain in PFNA.

CONCLUSIONBoth of PCCP and PFNA in treating patients with intertrochanteric fracture with risk external wall can receive good clinical effects, while the effects and therapy strategy for displacement of bone on the top of lateral wall should further study.

When we did compatibility testing, we found a case of leukemia with irregular antibody. The antibody specificity was identified as anti-Ce using panel-cell, and was IgG antibody. The anti-Ce antibody had both anti-C and anti-e activity. It is very difficult to find a Ce antigen negative blood for transfusion. The compatible donors rate is very low, only 2%-3%.

Objective To investigate the protein and mRNA expressions of Toll-like receptor 2 (TLR2) and Toll-like receptor 4 (TLR4) on colons of rats with trinitrobenzene sulfonic acid (TNBS)- induced colitis,and to evaluate the effects of probiotics.Methods Thirty male Wistar rats were randomly divided into normal control group (NC group),model control group(UC group) and probiotics-treated group(PC group).The experimental colitis was induced by TNBS/ethanol enema.Rats in PC group were fed with Bifico [live probiotics of combined hifidobacterium(Bif),lactobaeillus(Lac) and enteroeoccus] by 2.2?10~9 CFU/d for 4 weeks.Inflammatory scores were studied.Expressions of protein and mRNA of TLR2 and TLR4 were measured by Western blot and real-time quantitative polymerase chain reaction (PCR),respectively.Results Inflammatory scores in NC group,UC group and PC group were 4.35?0.88,10.25?1.36 and 7.94?0.85,respectively.The inflammatory scores in PC group were decreased compared with that in UC group (P

OBJECTIVEThe study aimed to review the treatment and prognosis of acute obstruction of colorectal cancers and to compare different treatment strategies of those cancers, and to evaluate the risk factors affecting perioperative complications.

METHODSClinical data of 184 patients with acute obstruction of colorectal cancer undergone operation were analyzed retrospectively.

RESULTSA total of 184 patients with acute obstruction of colorectal cancer was collected in this study, including 58 patients with proximal and 126 patients of distal colorectal cancers. Perioperative death occurred in 2/58 patients (3.4%) with distal colorectal cancer and 6/126 cases (4.8%) of distal colorectal cancer (P > 0.05). The overall perioperative complications in the two groups were not significantly different (P = 0.794). Among the 58 patients with proximal colorectal cancer, one patient underwent colostomy, but among the 126 patients with distal colorectal cancer, 41 patients underwent colostomy, showing a significant difference between the two groups (P = 0.002). ASA scores (grade 3 - 4), elderly age (≥ 70 years) and colon perforation peritonitis were independent prognostic factors associated with perioperative mortality and morbidity. Patients in the self-expandable metallic stent (SEMS) group had a significantly shorter hospital stay (25.4 ± 8.3) d than that in the emergency surgery group (32.8 ± 16.4) d, (P = 0.039).

CONCLUSIONSEndoscopic stent implantation provides an acceptable modality of palliation for acute proximal large bowel obstruction caused by malignancies. In acute colorectal cancer obstruction, SEMS can provide a minimally invasive management compared with surgical intervention.

OBJECTIVETo assess the relationships between iodine biological exposure and subclinical thyroid dysfunctions.

METHODSThe cross-sectional survey was performed to obtain the epidemiologic data of population in three communities with different iodine biological exposure: mild iodine deficiency [median urinary iodine concentration (MUI) of 50-99 microg/L], more than adequate iodine intake (MUI of 200-299 microg/L), and excessive iodine intake (MUI over 300 microg/L). Univariate and multivariate analysis (logistic regression analysis) were used to analyze the risk factors of subclinical hypothyroidism and subclinical hyperthyroidism.

RESULTSLogistic regression analysis with sex and age controlled suggested that more than adequate iodine intake (OR = 3.172, P = 0.0004) and excessive iodine intake (OR = 6.391, P = 0.0001) increased the risk of subclinical hypothyroidism, while excessive iodine intake decreased the risk of subclinical hyperthyroidism (OR = 0.218, P = 0.0001). Logistic regression analysis including interaction of iodine intake and antibodies [thyroid peroxidase antibody (TPOAb) and thyroglobulin antibody (TgAb)] suggested that excessive iodine intake was an independent risk factor of subclinical hypothyroidism (OR = 6.360, P = 0.0001), but independent protect factor of subclinical hyperthyroidism (OR = 0.193, P = 0.0001). More than adequate iodine intake and it's interaction with TgAb increased the risk of subclinical hypothyroidism independently, in addition, it decreased the risk of subclinical hyperthyroidism at the present of TPOAb.

CONCLUSIONBoth excessive iodine intake and more than adequate iodine intake could increase risk of subclinical hypothyroidism, supplement of iodine should be controlled to ensure MUI within the safe range.

Background Research showed that exposure of 530 nm monochromatic light can induce myopia in animal,and retinal Müller cells participate in the formation of myopia.However,the effect and mechanism of retinal Müller cells during the formation of monochromatic light induced-myopia is below understood.Objective This study was to investigate biologic characteristics of rat retina Müller cells and the expression of cell factors in Müller cells after being illuminated by the 530 nm monochromatic light,and discuss the role of the retina Müller cells in myopia induced by monochromatic light.Methods Immortalized rat retinal Müller cells were cultured with DMEM containing 10％ fetal bovine serum in a self-made cell incubator with monochromatic light by adjusting luminance of 530 nm LED source.The cells were exposed to 125,250 and 500 lx luminance respectively for 6,12 and 24 hours,and the cells without light-irradiation were used as control.The growth of the cells under the different light time and different illuminations was described by MTT as the absorbance at the wavelength 570 nm (A570),and cell cycle analysis of Müller cells was performed by flow cytometry 48 hours after cultured,and the expression of transforming growth factor-beta 1 (TGF-β1),tyrosine hydroxylase(TH),inducible nitric oxide synthase(iNOS) and basic fibroblast growth factor(bFGF)in the cells were detected by reverse transcription PCR(RT-PCR),respectively.Results The Müller cells were uniform in size with polygonal shape and defined edges.No statistically significant difference was found in the A570 value in the cells of the 125 lx and 250 lx illuminated groups compared with the control group in various time points(P＞0.05).However,significant lowing was seen in the A570 value in the cells of the 500 lx illuminating for 12 hours and 24 hours in comparison with the control group (P =0.013,0.001).Compared with the control group,the ratio of the number between G2 and G1 phase was not significantly declined in 125 lx,250 lx illuminating for 48 hours (P =0.073,0.330),and the ratio in the 500 lx illuminating group was significantly lower than those in the 250 lx illuminated group and the control group (P =0.028,0.038).RT-PCR revealed that the expression of TGF-β1 mRNA in the cells was higher in the 250 lx illuminated group than that of the 500 lx illuminated group (P=0.006).The expression of iNOS mRNA was gradually upregulated in the 250 lx illuminated group compared with the control group (P =0.001),but that in the 500 lx illuminated group was downregulated (P =0.000).The expression of bFGF mRNA was raised in the 125 lx and 250 lx groups but reduced in the 500 lx group when compared with the control group(P=0.002,0.000,0.005).Also,the expression of TH mRNA was significantly increased in the 250 lx group(P=0.000),but decreased in the 500 lx group(P=0.000,P=0.001).Conclusions The monochromatic light of 530 nm can inhibit the growth of rat Müller cells and downregulate the expression of myopia-related cell factors and therefore exert effect in the formation of myopia.

Background Dry eye is increasing gradually recently,but its etiology and manifestation are very diverse.Studies showed that menopause of adult females was one of the risk factors of dry eye.In addition,some inflammatory factors also participate in the pathogenesis and development.But the study on the relationship of sex hormone with inflammation and ocular surface damage is still below understanding.Objective This study was to investigate the expressing changes of interleukin (IL) and tumor necrosis factor-α (TNF-α) in conjunctiva and the manifestation of ocular surface in ovariectomized rat model.Methods Twenty clear female SD rats were randomized into the ovariectomized group and the sham operative group according to randomized number table.Ovariectomy was performed in the ovariectomized group,and abdominal myotomy without ovariectomy was performed in the sham operative group.Serum estrogen and androgen levels were detected by radiation immunoassay 3 months after operation.Schirmer Ⅰ test (S Ⅰ t) and corneal fluorescence staining were carried out in the rats before operation and 1 month,2 and 3 months after operation.The morphology of conjunctival epithelial cells was examined by hematoxylin & eosin staining at the 3rd month after operation.The expressions of IL-17A,IL-1 β,IL-6 and TNF-α in conjunctiva were semi-quantitative analyzed by immunohistochemistry and Western blot.The use and care of the animals complied with State Science and Technology Commission Regulations for the Administration of Affair Concerning Experimental Animals.Results Serum estrogen levels were (23.53 ± 1.65) pg/L and (47.89 ± 1.05) pg/L 3 months after surgery in the ovariectomized group and the sham operative group,respectively; the serum androgen levels were (1.84±0.09) ng/L and (2.47±0.12)ng/L in the ovariectomized group and the sham operative group,respectively,showing a significant decline of serum estrogen and androgen levels in the ovariectomized group compared with the sham operative group (t=-35.37,-12.13,both at P＜0.01).No significant differences were seen in S Ⅰ t between the two groups among various time points (Fgroup =0.38,P =0.55 ; Ftime =0.13,P =0.72 ; Finteraction =0.39,P =0.76).No obvious fluorescence staining was seen in the cornea of both the ovariectomized group and the sham operative group.The histopathological examination showed that the layers of rat conjunctival epithelial cells increased with the disordered arrangement in the ovariectomized group.Immunochemistry showed that the expressions of IL-17A,IL-1β,IL-6 and TNF-α (A values) were significantly higher in the ovariectomized group than those in the sham operative group (IL-17A:t=8.22,P＜0.01 ;IL-1β:t=16.43,P＜0.01 ;IL-6:t=13.44,P＜0.01 ;TNF-α:t=16.26,P＜0.01).Western blot assay showed the similar results (IL-17A:t=19.41,P＜0.01 ;IL-1β:t=12.63,P＜0.01 ;IL-6:t=17.17,P＜0.01 ;TNF-α:t=15.19,P＜0.01).Conclusions Serum estrogen and androgen levels drop obviously,and there is an up-regulation of IL and TNF-α expression in conjunctiva tissue in the ovariectromized SD rats.However,no obvious dry eye-related sign occurs.
