Objective To investigate the clinical effects of arthroscopic patelloplasty combined with lateral patellar retinaculum release and circumpatellar denervation for treatment of moderate and severe patellofemoral osteoarthritis.Methods A retrospective case-control study was done on 80 patients with moderate to severe patellofemoral osteoarthritis who were treated in our hospital between March 2013 and March 2015.According to treatment methods,the patients were divided into two groups:Group A including 40 cases (22 cases of Outerbridge grade Ⅲ degree and 18 cases of Outerbridge grade Ⅳ) undergone arthroscopic debridement,and Group B including 40 cases (22 cases of Outerbridge grade Ⅲ degree and 18 cases of Outerbridge grade Ⅳ) undergone arthroscopic patelloplasty combined with lateral patellar retinaculum release and circumpatellar denervation.The Kujula scores and Lysholm scores of the patellofemoral joint were compared between the two groups before and after operation.The lateral patellofemoral angle was measured according to patellar axial X-ray performed 3 months after operation to evaluate patellofemoral joint function.Results All patients were followed up for 13-36 months (average 19.8 months).The patellofemoral joint scores of the two groups was increased at different degrees after operation.In moderate patellofemoral osteoarthritis patients,at 3 months after operation and the last follow-up of Group B,Kujula scores [(85.1 ± 6.8)points,(86.8 ± 4.6)points] and Lysholm scores [(88.1 ± 1.8) points,(88.4 ± 2.3) points] were higher than that of Group A [(78.1 ± 5.7) points,(78.3±5.3)points,(82.4 ±2.9)points,and (82.5 ±2.5)points] (P＜0.05).In each group,the Kujula scores and Lysholm scores at 3 months after operation and the last follow-up were improved to be higher than preoperation (P ＜ 0.05),with insignificant statistical difference between the two groups (P ＞ 0.05).According to the Lysholm scores,the excellent rate after operation in Group B (86％) was higher than that of Group A (55％) (P ＜ 0.05).For patients with severe patellofemoral osteoarthritis,Kujula scores [(72.3 ± 5.3) points,(72.7 ± 3.6) points] and Lysholm scores [(75.1 ± 1.9) points,(75.3 ± 2.3) points] at 3 months postoperatively and at the last follow-up in Group B were higher than that of Group A [(70.8 ± 5.2) points,(71.1 ± 4.2) points,(73.4 ± 2.8) points,and (73.6 ± 2.5) points],but the difference was not statistically significant (P ＞ 0.05).Within each group,although the Kujula scores and Lysholm scores at 3 months postoperatively and at the last follow-up were improved compared with before operation,but the difference was not statistically significant (P ＞ 0.05).According to the Lysholm scores,although the excellent rate after operation of Group B (33％) was higher than that of Group A (28％),with insignificant statistical difference (P ＞ 0.05).No matter Outerbridge Ⅲ or Ⅳ patellofemoral osteoarthritis a patient was,the lateral patellofemoral angle of Group A after operation had no significant improvement (P ＞ 0.05),while Group B showed significant improvement after operation (P ＜0.01).Group B had better improvements than that of Group A (P ＜0.01).Conclusions Compared with simple arthroscopic debridement,patelloplasty combined with lateral patellar retinaculum release and circumpatellar denervation can better relieve the symptoms of moderate patellofemoral osteoarthritis and improve knee function.But for patients with severe patellofemoral osteoarthritis,this method is not effective.

Objective To explore the effects of anxiety-like behaviors on the levels of sex hormones and severity of erectile dysfunction(ED) in young men.Methods A total of 120 young men with ED,between the ages of 23 and 35 years,were prospectively studied,and all of them were the outpatients from the Affiliated Hospital of Jining Medical University from January 2012 to October 2013.Self-Rating Anxiety Scale (SAS) was used.According to the scores of SAS,the patients were divided into four groups.26 were rated by SAS as in the normal,36 in the mild,32 in the moderate and 26 in the severe state of anxiety.The levels of serum sex hormone (FSH,LH,PRL,T,E2) were detected by immunochemiluminometric assays.ED was assessed using the IIEF-5.Further,the responses were divided into three diagnosing groups on the basis of cutoff scores for IIEF-5.The relationship between the SAS scores of measuring anxiety,serum sex hormone levels,and the indicators for ED,Spearman rank correlations were carried out.Results Comparing with the normal control group,the levels of serum sex hormones (FSH,LH,PRL,E2) increased in other groups,but there were no significant differences (F=0.28,P=0.08 ; F=2.91,P=0.06; F=0.90,P=0.44; F=0.80,P=0.15).The levels of serum testosterone and the scores of IIEF-5 in the moderate and severe anxiety group decreased.The more severe symptoms of anxiety,the more likely that the ED would occur(x2=72.423,P=0.00),and ED was significantly positively correlated with anxiety(r=0.637,P=0.00).Testosterone played the partial intermediary role on the relationship between anxiety score and the IIEF-5 score.Conclusion Anxiety may contribute to ED through disturbing the sex hormone and lowering the level of serum testosterone.

Objective To observe the effect of hydrogen on ultraviolet B (UVB)-induced oxidative damage to skin fibroblasts.Methods Primary human skin fibroblasts from foreskin tissues were divided into five groups:normal control group receiving no treatment,hydrogen control group treated with hydrogen-rich saline,UVB group receiving irradiation only,post-treatment group irradiated with UVB followed by hydrogen-rich saline treatment,and pre-treatment group treated with hydrogen-rich saline followed by UVB irradiation.The dose of UVB was 30,60 and 90 mJ/cm2 in the cell proliferation assay and 90 mJ/cm2 in the other experiments.Methyl thiazolyl tetrazolium (MTT) assay was performed to evaluate the proliferative activity of fibroblasts,a chemiluminescence method to estimate the activity of superoxide dismutase (SOD) and catalase as well as to determine the level of malondialdehyde in the culture supernatant of fibroblasts,enzyme linked immunosorbent assay (ELISA) to determine the supernatant level of 8-isoprostane-prostaglandin F2α (8-iso-PGF2α),Western blot to detect the expression of heme oxygenase-1 (HO-1) in fibroblasts.One-factor analysis of variance was conducted to assess differences in these parameters among these groups.Results UVB irradiation decreased the proliferative activity (absorbence value at 490 nm) of fibroblasts in a dose-dependent manner.Both the pre-treatment group and post-treatment group showed a statistical increase in proliferative activity of cells compared with the corresponding UVB control groups (all P ＜ 0.05).The activity of SOD and catalase as well as the protein expression of HO-1 were significantly higher (all P ＜ 0.05),whereas the supernatant levels of malondialdehyde and 8-iso-PGF2α were statistically lower (both P ＜ 0.05) in the pre-treatment group and post-treatment group than in the UVB control group.Conclusion Hydrogen may mitigate UVB-induced oxidative damage to skin fibroblasts.

Objective To investigate the therapeutic effect of the meso-cavo-atrial shunt (MCAS) in the treatment of combined Budd-Chiari syndrome (BCS). Methods The clinical data of 17 cases of combined BCS with all or bilateral hepatic vein occlusion and long range occlusion or obstruction of inferior vena cava (IVC) were admitted to the Qilu Hospital from February 2000 to May 2004. All patients were treated by MCAS with artificial blood vessels. The pre- and postoperative clinical symptoms, the IVC and portal venous (PV) pressures, the incidence of postoperative complications and the patency rate of the artificial vessels were analyzed. The survival of patients was analyzed using the Kaplan-Meier analysis, and the data were analyzed using the chi-square test and t test. Results No patient died during the perioperative period, and the symptoms of 15 patients disappeared or were relieved after operation, with a significant difference compared with those before operation (χ2 =9.78, P <0. 05 ). Three patients had complications after the operation. The postoperative PV and IVC pressures were decreased by 1.2 cm H2O (1 cm H2O =0.098 kPa) and 18.5 cm H2O, respectively. There were significant differences in the decrease of IVC and PV pressures ( t = 2.38, 3.06, P < 0.05 ). The 1-, 3-, 5-year survival rates were 16/17, 15/17 and 14/17, respectively, and the 5-year patency rate of the artificial vessels was 14/17.Conclusions MCAS can simultaneously relieve IVC and PV hypertension for patients with combined BCS. The postoperative complication rate was decreased, the 5-year survival rate and the patency rate of the artificial vessels were improved after the treatment, so MCAS is an optional surgical method for treating combined BCS.

Objective To measure the morphological parameters of the acromion with CT and to analyze their match with the hook plate. Methods From October 2009 to February 2010,spiral CT scanning (with Somatom Emotion16) and three-dimensional reconstruction of bilateral shoulders were conducted in 61 Chinese subjects.They were 24 men and 37 women,aged from 20 to 83 years (average,45.2 years).The thickness,length and width of the acromion were measured and the subacromial shape was observed with software of the CT system to analyze the match between the hook plate and the acromion.Results The mean thickness of the acromion was 0.85 ± 0.13 cm in all subjects,0.94 ± 0.12 cm in males and 0.79 ± 0.10 cm in fe males,with a significant difference between males and females ( t =2.382,P =0.202).The mean acromion length was 2.08 ± 0.20 cm in all subjects,2.09 ± 0.21 cm in males and 2.06 ± 0.18 cm in females,with no significant difference between males and females( t =1.541,P =0.129).The mean acromion width was 3.81 ± 0.52 cm in all subjects,4.34 ± 0.32 cm in males and 3.47 ± 0.25 cm in females,with a significant difference between males and females ( t =2.296, P =0.025 ). Conclusions The acromial morphology varies significantly between genders in Chinese population,particularly in the thickness and width.It is,therefore,necessary to modify the morphological parameters of the hook plate to match better the gender difference in Chinese population.It is optimal that the hook plate should allow individualized pre-moulding to enhance its therapeutic efficacy.

OBJECTIVEIn order to get the method for improving the salt resistance of Lycium ruthenium seeds and seedlings under NaCl stress, the seed germination and physiological characteristics of L. ruthenium seedlings was studied.

METHODSeveral physiological indexes of L. ruthenium seeds under NaCl stress, such as the germination rate (Gr), germination vigor (Gv), germination index (Gi), vigor index (Vi), and relative salt damage rate were measured. Other indexes of the seedlings like relative water contents (RWC) , chlorophyll contents, soluble protein contents, electrolyte leakage, the contents of malondialdehyde (MDA), and peroxidase (POD) were also measured.

RESULTNaCl at lower concentration could promote the seed germination but inhibit the seed germination at higher concentration. After the treatment by CaCl2 at the different concentrations, all germination indexes were increased. With the increase of salt concentration, the relative water contents and the contents of chlorophyll were decreased, the content of MDA and electrolyte leakage were increased. The change trend of POD activity showed the first increase and then decrease with the increase of salt concentration, which was similar to that of the soluble protein. After the treatment by CaCl2, relative water contents, chlorophyll and POD activities were decreased more slowly, and also electrolyte leakage and MDA contents increased slowly.

CONCLUSIONThe CaCl2 could significantly alleviate the damages to the seeds and seedlings of L. ruthenium under NaCl stress, and promote the salt resistance to the seeds and seedlings of L. ruthenium.
