Objective: To investigate the influence of Swiss ball exercises on clinical efficacy and stability of lumbar vertebra in patients with protrusion of lumber intervertebral disc. Method: Thirty patients with non-acute protrusion of lumber intervertebral disc were divided by gender and clinics orders into control and exercises group. Roland Morris questionaire(RMQ) and visual analogue seale(VAS) were selected as pain assessment. Pain, abdominal and back muscle strength were assessed respectively before treatment, 2 and 4 weeks after Swiss ball exercises. Both Swiss ball exercises and lumbar traction were used in exercises group. Lumbar traction was used in control group. Result: Compared with before treatment, RMQ and VAS scores decreased significantly after 4 weeks in control and exercises groups (P<0.05, P<0.01). Compared with control, RMQ and VAS scores in exercises group decreased significantly after 2 and 4 weeks respectively (P<0.05, P<0.01). Compared with control, abdominal and back muscle strength in exercises group increased significantly after 2 and 4 weeks respectively (P<0.05, P<0.01). Conclusion: The low back pain symptom of patients with protrusion of lumber intervertebral disc decreased significantly and abdominal and back muscle strength increased significantly by beth Swiss ball exercises and lumbar traction. The stability of lumbar vertebra of patients with protrusion of lumber intervertebral disc increased significantly.

Objective To evaluate the efficacy of Jianpi-Xiaozheng recipe combined with chemotherapy in patients with late gastric cancer. Methods A total of 124 patients with late gastric cancer were randomly divided into a control group and a treatment group by random number table method, with 62 cases in each group. The patients in the control group received chemotherapy with S-1 and oxaliplatin (SOX), and those in the treatment group received Jianpi-Xiaozheng recipe combined with SOX chemotherapy. The treatment response was evaluated using the response evaluation criteria in solid tumors. The quality of life and physical status were evaluated with the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (QLQ-C30) and Karnofsky Performance Status (KPS), respectivly. The serum levels of tumor biomarkers, carbohydrate antigen 199 (CA199) and carbohydrate antigen 72-4 (CA72-4) were detected before and after treatment. Results The response rate (complete or partial response) in the treatment group was significantly higher than that in the control group (62.9%vs. 43.5%;χ2=4.665, P=0.031). The scores of QLQ-C30 (46.8 ± 6.3 vs. 42.2 ± 5.9;t=4.196, P=0.001) and KPS (79.1 ± 7.8 vs. 72.0 ± 7.5;t=5.167, P=0.000) in the treatment group were significantly higher than those in the control group. The serum levels of CA199 (61.7 ± 16.5 U/ml vs. 113.3 ± 21.4 U/ml;t=15.036, P=0.000) and CA72-4 (27.9 ± 9.6 U/ml vs. 34.3 ± 9.7 U/ml;t=3.693, P=0.001) in the treatment group were significantly lower than those in the control group. Conclusions Jianpi-Xiaozheng recipe combined with chemotherapy can increase response rate, decrease the serum levels of tumor biomarkers, and improve the quality of life in patients with late gastric cancer.

Objective To clarify evaluation methodology of the accuracy of differential diagnosis of meningioma and glioma,taking magnetic resonance imaging (MRI) and vascular endothelial growth factor (VEGF) into account.Methods According to the unified standard of design,114 cases were selected,which were diagnosed by postoperative pathological in Shanxi Cancer Hospital from March 2010 to October 2012.On the basis of hospital routine inspection,all patients needed MRI scan,enhancement scan,VEGF,ALP and LDH,with pathological diagnosis of glioma or meningioma.Using ROC curve analysis which took VEGF,T2WI into account,the accuracy of differential diagnosis could be evaluated.Results The results showed that the differential diagnosis accuracy were high relatively,the area under the ROC curve was 91.34 ％.When the T2WI were equisignal,low signal or high signal respectively,the area under the curve ROC were 97.62 ％,90.00 ％,88.34 ％.Conclusion To consider the MRI T2WI and VEGF,ROC curve regression model analysis can enhance the differential diagnosis accuracy of meningioma and glioma.

OBJECTIVETo analyze the clinical phenotype of a Chinese pedigree affected with Papillon-Lefevre syndrome(PLS) and detect mutation of CTSC gene.

METHODSClinical phenotypes were noted, and oral examination for the proband was carried out for the clinical diagnosis of PLS. PCR and Sanger sequencing were used to identify potential mutation of the CTSC gene. Functional effect of the mutation was predicted with SIFT and PolyPhen-2. Swiss-Port was used to predict the tertiary structure of wild type and mutant proteins. The mRNA and protein expression were analyzed by real-time PCR and Western blotting.

RESULTSA homozygous mutation c.901G>A (p.G301S) in exon 7 of CTSC gene was identified in the patient. Both parents of the patient had carried a heterozygous c.901G>A mutation. The mutation was located in the conserved region of CTSC enzyme and was predicted to be damaging by changing the structure of the protein, which could affect the activity of Cathepsin C. However, no significant difference was found in the expression of p.G301S variant at the mRNA and protein levels compared with that of the wild type CTSC gene.

CONCLUSIONThe c.901G>A mutation of the CTSC gene was first reported in China, which has expanded its mutation spectrum.
