OBJECTIVETo explore clinical efficacy of double Endobutto reconstituting coracoclavicular ligament combined with repairing acromioclavicular ligament in stage I in treating acromioclavicular dislocation with Rockwood type III - V .

METHODSFrom January 2010 to September 2013, 56 patients with Rockwood type III - V acromioclavicular dislocation were treated by operation, including 20 males and 36 femlaes, aged from 32 to 52 years old with an average of 38.5 years old. Twenty-five patients were on the left side and 31 cases on the right side. The time from injury to operation was from 3 to 14 days, averaged 7 days. All patients were diagnosed as acromioclavicular dislocation with Rockwood type III - V, and double Endobutto were used to reconstituting coracoclavicular ligament, line metal anchors were applied for repairing acromioclavicular ligament. Postoperative complications were observed, Karlsson and Constant-Murley evaluation standard were used to evaluate clinical effects.

RESULTSAll patients were followed up from 8 to 24 months with average of 11 months. According to Karlsson evaluation standard at 6 months after operation,42 cases were grade A, 13 were grade B and 1 was grade C. Constant-Murley score were improved from (42.80±5.43) before operation to (91.75±4.27) at 6 months after operation. All items at 6 months after operation were better than that of preoperative items. Forty-eight patients got excellent results, 7 were moderate and only 1 with bad result. No shoulder joint adhesion, screw loosening or breakage were occurred during following up.

CONCLUSIONDouble Endobutto reconstituting coracoclavicular ligament combined with repairing acromioclavicular ligament in stage I for the treatment of acromioclavicular dislocation with Rockwood type III - V could obtain early staisfied clinical effects, and benefit for early recovery of shoulder joint function.

AIM: To detect the serum proteomic patterns in patients of breast cancer by the method of SELDI-TOF-MS and CM10 ProteinChip, and to screen the biomarker candidates, build and validate the diagnostic models, and evaluate its clinical value in surveillance and follow-up after operation. METHODS: The SELDI-TOF-MS technology and CM10 ProteinChip were used to detect the proteomic patterns of serum from 63 breast cancer patients and 40 healthy women. The biomarker candidates were screened and the diagnostic models were constructed by ZJU-PDAS software. Meanwhile, the model was blind-validated in another 23 patients and 20 healthy women. At the same time, 16 serum samples were detected to evaluate its value in surveillance and follow-up after operation. RESULTS: The best model was composed by two protein peaks (BC1/3.9 kD and BC2/5.6 kD) with its sensitivity and specificity of 87.30% (55/63) and 95.00% (38/40), respectively. The sensitivity and specificity in the blind-validation of new cases were 95.65% (22/23) and 85.00% (17/20), respectively. The diagnostic efficacies were the same to the patients of different stages (P>0.05). The expression of BC1 increased while BC2 decreased after operation. The expression of BC2 in the patients with recurrence or metastasis was higher than that in the tumor-free survivors (P<0.05). CONCLUSION: This method shows its potential in detection, surveillance and follow-up after operation. The method is also useful for screening the novel and better biomarkers in breast cancer.

Objective To study the relationship between common photoallergens and melasma.Methods Twenty allergens were selected according to the National Diagnostic Criteria for Photosensitive Dermatitis induced by cosmetics,National Diagnostic Criteria for Contact Dermatitis induced by cosmetics and National Diagnostic Criteria for Occupational Skin Diseases.Based on the standard procedures for photopatch test recommended by the British Photodermatology Group (BPG),photopatch test was performed on 50 patients with melasma and 30 normal controls.Results The positivity rate of photopatch test was 48.0%(24/50)in patients suffering from melasma,significantly higher than in the controls[23.33%(7/30),P<0.05].Conclusion Patients with melasma appear more likely to have positive photopatch test than normal controls.

BACKGROUND:Umbilical cord blood stem cel s can be differentiated into functional liver cel s in vivo, instead of mature liver cel s in the treatment of liver diseases. OBJECTIVE:To observe the effect of umbilical cord blood stem cel transplantation on decompensated cirrhosis in rats. METHODS:Twenty Sprague-Dawley rats were enrol ed and given 40%carbon tetrachloride peanut oil to make decompensated cirrhosis models. Eight weeks after modeling, model rats were randomized into control and experimental groups (n=10 per group), and subjected to injection of umbilical cord blood stem cel suspension (2 mL, 1.0×107/L) or cel culture medium (2 mL) via the tail vein, respectively. At 4 weeks after injection, levels of serum aspartate aminotransferase, alanine aminotransferase, albumin, total bilirubin, hyaluronic acid, laminin, procol agen III and type IV col agen were detected;rat liver tissues were sliced for pathological observation. RESULTS AND CONCLUSION:Compared with the control group, the albumin level was significantly increased but the levels of serum aspartate aminotransferase, alanine aminotransferase, total bilirubin, hyaluronic acid, laminin, procol agen III and type IV col agen decreased significantly in the experimental group (P<0.05). From the pathological view, severity of liver cirrhosis was lower in the experimental group than the control group. Therefore, umbilical cord blood stem cel transplantation can effectively restore the liver function of decompensated cirrhosis in rats.

Objective To investigate the optimal regimen of narrow-band ultraviolet B (NB-UVB) phototherapy in the treatment of chronic actinic dermatitis (CAD),and to analyze factors influencing treatment compliance.Methods Demographic data,results of photobiological tests,treatment parameters and clinical responses were collected from CAD patients who received NB-UVB phototherapy in Huashan Hospital affiliated to Fudan University from January 2008 to June 2015,and were reviewed retrospectively.Statistical analysis was done by using two independent samples t-test and chi-square test with SAS9.3 software to compare the clinical data between patients who completed and did not complete the NB-UVB phototherapy.Results A total of 79 CAD patients with Fitzpatrick skin type Ⅳ received NB-UVB phototherapy.Of these patients,61 (77％) completed the whole treatment,while 18 (23％) dropped out because of intolerance to the NB-UVB radiation.Among the 61 patients who completed the treatment,the average initial,final and cumulative radiation doses of NB-UVB were (0.08 ± 0.01) J/cm2,(0.32 ± 0.08) J/cm2and (5.9 ± 2.5) J respectively,and patients received (28 ± 8) times of treatment in average.When the radiation dose went up to 0.30 J/cm2,most skin lesions were cleared in 52 (85％) patients.A total of 19patients received phototesting again after the end of phototherapy.Among 16 patients sensitive to ultraviolet A (UVA) before the treatment,6 had normal minimal erythema dose to UVA (UVA-MED),and another 6 had improved UVA-MED after the treatment.Among 16 patients sensitive to UVB before the treatment,11 got normal UVB-MED and another 3 had improved UVB-MED after the treatment.Univariate analysis showed no significant differences in gender,age,duration of the disease,sensitivity to UVA and UVB radiation,results of photopatch test and patch test between the patients who completed and did not complete the treatment (all P ＞ 0.05).Conclusions The appropriate NB-UVB phototherapy for CAD patients should start at an initial radiation dose of 0.08 J/cm2 in spring and end at a final radiation dose of 0.30 J/cm2 for about 28 sessions,which can effectively reduce the photosensitivity to both UVA and UVB in CAD patients.Additionally,NB-UVB phototherapy can be applied in CAD patients of different gender,age,disease duration and photosensitive condition.

Methods Fibroblasts were irradiated by a single exposure of 36 seconds to 40 mJ/cm 2 UVB and at the same time incubated with, or without, tempol and detected twenty-four hours later. SOD activity and lipid peroxidation,as shown by accumulation malondialdehyde (MDA) were detected by biochemical assay. Expression of MMP-1 and MMP-3 (mRNA level) were examined by Semi-quantitative RT-PCR. Results 40 mJ/cm 2 UVB significantly inhibited cell proliferation rate to (84?8)% (P

OBJECTIVETo study on the reliability of the Akagi line as a reference axis to guide for rotational alignment of the proximal tibial component in total knee arthroplasty (TKA) the rotational alignment reference bony landmarks of the proximal tibial component on magnetic resonance image (MRI) were measured.

METHODSFrom January 2010 to December 2013, 80 normal knees of Chinese volunteers including 35 males and 45 females with an average age of (35.4±6.1) years were reviewed. The images of the knees were obtained by MRI. The surgical epicondylar axis (STEA) was identified in the femoral transverse sections and then was projected to the side of tibia, forming the SETA'. A line connecting the medial border of the patellar tendon and the middle of the posterior cruciate ligament insertion (Akagi line) and its vertical line (AK), as well as a line connecting the medial 1/3 of the patellar tendon and the middle of the posterior cruciate ligament insertion and its vertical line (AP), were identified in the tibial transverse sections. The angles were measured between the AK, AP and STEA'.

RESULTSThe angle between AK and STEA' was (0.59±2.07)°, and there was no significant difference between the two lines (t=-2.54, P=0.13). The mean angle between AP and STEA' was (3.21±2.04)°, and there was a significant difference between the two lines (t=14.05, P<0.05). There was a significant difference between the AK and AP (t=-11.68, P<0.05).

CONCLUSIONThe reliability of the Akagi line as a reference axis to guide for rotational alignment of the proximal tibial component in TKA is good.

Objective To explore effects of heroin and ephedrine on the histological structure and ChAT activity of hypothalamus and hippocampus of filial mice. Expression of Bcl-2 associated X protein(Bax protein) and keratinocyte growth factor(KGF) of hypothalamus and hippocampus were measured. Methods One hundred and eight filial mice were given intraperitoneal injection of heroin and ephedrine by gradually increase of doses, apoptosis and expression of Bax protein and KGF of hypothalamus and hippocampus were observed by Giemsa staining and immunohistochemistry, and the ChAT activity was detected by colorimetry. Results After administration of heroin and ephedrine at 5,10,15,20 days, the number of apoptotic cells and expression of Bax protein and KGF of hypothalamus and hippocampus were significantly increased and ChAT activity was lower than those of the control group(P<0.05 or P<0.01). There were differences between heroin group and the ephedrine group in the above-mentioned four indexes (P<0.05 or P<0.01). The number of apoptotic cells and Bax protein and KGF immunopositive neurons of hypothalamus and hippocampus increased by the increase in dose of heroin and ephedrine. Conclusions Heroin and ephedrine had great effect on the histological structure and ChAT activity of hypothalamus and hippocampus of filial mice, and this effects would be related to the cell apoptosis of hypothalamus and hippocampus.

In chronic kidney disease (CKD), inflammatory responses during the progression of renal tissue and tissue injury related causes its progression to end-state renal disease. Among them, nuclear factor (nuclear factor, NF)-kappaB signaling pathway by regulating the corresponding nuclear expression of target gene transcription, as well as affecting the synthesis of inflammatory mediators, induction of inflammation lead to kidney damage and renal fibrosis. Some single herbs and their extracts (such as Astragali Radix, Scutellariae Radix, Ginkgo Folium) and some traditional Chinese medicine (such as Danggui Buxue decoction, Qilian decoction) can reduce the inflammatory damage induced by renal tissue NF-kappaB signaling pathway and delay the progression of CKD.
