Objective To compare the clinical application of endoscope system and dimensional disc hole mirror, and its advantages of percutaneous transforaminal endoscopic discectomy TESSY technology. Methods Two hundred and eighty patients with lumbar disc herniation randomly divided into foraminal mirror group and endoscopic group(140 cases for each groups). Patients in foraminal mirror group were given TESSY removal of nucleus pulposus through lateral approach road,while in endoscopic group were given posterior approach discectomy. The operation time,bleeding volume,postoperative time,incision length,waist and leg waist pain and functional recovery were recorded. Results The operation incision length in foraminal mirror group was(0. 8 ± 0. 1)mm,significantly shorter in the endoscopic group((1. 7 ± 0. 2)mm),the amount of bleeding in foraminal mirror group was( 9. 8 ± 4. 3 )ml,significantly less than the endoscopic group(( 78. 6 ± 18. 8)ml). The above data were statistically significant difference( t =21. 753,19. 280;P ﹤0. 01 ). The getting out of bed time after operation was(0. 3 ± 0. 1)d,significantly earlier than that in the endoscopic group ((3. 5 ± 0. 8)d;t=21. 451;P﹤0. 01). VAS scores of patients in two group at postoperative were(7. 4 ± 1. 8) and(7. 3 ± 1. 6),significantly decreased than that of preoperative((2. 7 ± 1. 7)and(2. 5 ± 1. 6);t=10. 259, 11. 465;P﹤0. 01),But there were no significant differences between the two groups before and after treatment ( P﹥ 0. 05 ). After treatment,waist function recovery in the two groups were 97. 1%( 136/140 ),95. 7%(134/140),and the difference was significant(χ2 =0. 415,P﹥0. 05). Conclusion Foraminal mirror TESSY technique in the treatment of lumbar disc herniation with microendoscopy discectomy with small incision is proved a good approach with less bleeding,postoperative early rehabilitation.

Objective To study the changes of lipopolysaccharide binding protein (LBP) in the serum of Wistar rats with obstructive jaundice and to investigate its potential mechanism.Methods Eighty male Wistar rats were randomly divided into obstructive jaundice group (OJ group, n =40) and sham operation group (SO group, n =40). Before operation and the 5th, 10th, 15th, 20th day after common bile duct ligation, the levels of LBP, endotoxin, tumor necrosis factor alpha (TNF ?) and interleukin 6 (IL 6) in plasma were detected in all the rats. Results LBP levels in serum increased significantly in OJ group on the 10th day after operation compared with those of SO group. Moreover, LBP levels gradually increased in OJ group with the prolongation of obstructive time. A positive correlation existed between serum LBP and plasma endotoxin, TNF ? and IL 6.Conclusion The study demonstrates that LBP in serum is high and plays an important role in the pathogenesis of multiple organ injury secondary to obstructive jaundice. It may be an appropriate way to treat patients with obstructive jaundice by decreasing LBP levels in serum.

Objective To study the influence of postoperative chemotherapeutic regimens on menstruation in pre-menopausal patients with breast cancer. Methods 120 pre-menopausal patients with breast cancer from Jan 2010 to Dec 2012 were followed-up. The occurrence rate and recovery rate of chemotherapy-induced amenorrhea (CIA) were analyzed. The relationship between different chemotherapeutic regimens and CIA of various age groups was analyzed. Results 120 women were followed-up, 94 (78.3 %) patients developed CIA. The frequency of CIA in younger patients (≤ 35 years) was significantly lower than that in patients older than 35 years (P < 0.05). 50 (53.2 %) patients returned to normal menses. The recovery situation of CIA was significantly different among various age groups (P < 0.05). The difference of the occurrence rate of CIA was not statistically significant between the patients who received anthracycline-based chemotherapy and docetaxel-based chemotherapy (P > 0.05). Conclusions Age is an important influence factor of the CIA. Chemotherapy has less influence on the menstruation of younger patients (≤35 years) and most amenorrhea is reversible. The effects of sequential addition of taxanes in chemotherapy and anthracyclines alone on menstruation have no significant difference.

Objective To retrospectively analyze the clinical and pathological characteristics of breast cancer in women ≤ 40 years of age.Methods One hundred and thirty one young (≤ 40 years) female patients with breast cancer pathologically confirmed in the General Hospital of PLA from January 1 st 2008 to December 31st 2012 (young group) were collected,and 262 elderly (41-69 years) female patients with breast cancer in the same period (old group) were collected as control using the random number table method.The clinicopathological characteristics involved TNM staging,histological grade,the expression levels of estrogen receptor (ER),progesterone receptor (PR),human epidermal growth factor receptor-2 (Her-2) and clinical stage of the two groups were contrastively analyzed.Results Compared with elderly patients,young female patients with breast cancer had lower positive rate of ER or PR (64.9％ vs.76.7％;x2 =6.171,P =0.013),higher positive rate of Her-2 (26.7％ vs.15.3％;x2 =7.415,P =0.006) and higher histological grade (grade Ⅱ 38.2％ vs.35.1％;grade Ⅲ 55.7％ vs.49.6％;x2 =6.835,P=0.033).There were no significant differences in T stage (x2 =1.764,P =0.623),N stage (x2 =0.129,P =0.988),clinical stage (x2 =4.916,P =0.178),molecular subtype (x2 =7.475,P =0.058) and different surgical procedures (x2 =0.913,P =0.339) between the two groups.Conclusion Young (≤ 40 years) female patients with breast cancer have specific clinical and pathological characteristics including higher histological grade,higher positive rate of Her-2,lower positive rate of ER or PR and higher degree of malignancy,who should be diagnosed and treated as soon as possible.

Objective Many studies have suggested that cardiovascular risk factors seem to be more common in psoriasis patients than in general population.In this study we aimed to investigate the prevention and treatment of cardiovascular risk in psoriasis patients by Framingham cardiovascular risk assessment in patients with psoriasis vulgaris and normal people using Framingham score.Methods We conducted a prospective study including 90 outpatients with psoriasis vulgaris and 137 controls without psoriasis from October 2015 to October 2016 in our hospital.All psoriasis patients were diagnosed clinically and histopathologically.The severity of psoriasis was assessed according to the psoriasis area and severity index (PASI) score.Along with a thorough medical history and physical examination, serum lipid profile, blood pressure and fasting plasma glucose tests were carried out.The 10-year Framingham risk score (FRS) for general cardiovascular disease included indexes concerning age, gender, total cholesterol, HDL-cholesterol, systolic blood pressure and smoking history.Results We found the 10-year FRS was significantly higher in patients with psoriasis vulgaris than in controls (P<0.05).The 10-year FRS was in positive relation with gender(r=0.358), age(r=0.678) and course of disease(r=0.257).No relation has been found in 10-year FRS and psoriasis features(r=0.184, P>0.05).No significance was found in the 10-year FRS of patients with mild and severe psoriasis (P>0.05).FRS was significantly higher in male patients and in patients above 50 years old (P<0.05).Conclusion Psoriasis patients, especially the older male patients, tend to have high risks of cardiovascular disease.Therefore, risk assessment for cardiovascular diseases should be conducted in psoriasis patients, and complications should be actively prevented and treated.

To study the effect of cholesterol and 25-OH-cholesterol on cholesterol metabolism in HepG2 cells and the effect of coptisine (Cop) extracted from Coptidis Rhizoma (CR) in reducing and regulating cholesterol. In this study, TC, TG, LDL-c and HDL-c were measured by biochemical analysis; mRNA and protein expressions of LDLR, HMGCR and CYP7A1 were detected by qRT-PCR and Western blot. According to the results, cholesterol and 25-OH-cholesterol inducing could decrease in mRNA and protein expressions of LDLR and CYP7A1, so as to increase TC and LDL-c contents. However, Cop could up-regulate mRNA and protein expressions of LDLR and CYP7A1 and down-regulate that of HMGCR, so as to reduce TC and LDL-c levels. These findings suggested that Cop has potential pharmacological activity for reducing cholesterol, and may reduce cholesterol by regulating mRNA and protein expressions of key genes involved in cholesterol metabolism, such as LDLR, CYP7A1 and HMGCR. This study laid a firm theoretical foundation for developing new natural drugs with the cholesterol-lowering activity.

OBJECTIVETo study the effects of Zuogui Pill (, ZGP) and Yougui Pill (, YGP) on the expressions of brain-derived neurotrophic factor (BDNF) and cyclic adenosine monophosphate (cAMP)/protein kinase A (PKA) signaling of axonal regeneration in the Lewis rats with experimental autoimmune encephalomyelitis (EAE), in order to explore the possible mechanism of ZGP and YGP on promoting axonal regeneration.

METHODSThe rats were randomly divided into normal control (NC), model (MO), prednisone acetate (PA), ZGP and YGP groups. The EAE model of rat was established by injecting antigen containing myelin basic protein (MBP)68-86. The brain and spinal cord were harvested on the 14th and 28th day post-immunization (PI), the protein and mRNA expression of BDNF and PKA in the brain and spinal cord of rats were detected by Western blot analysis and real-time quantitative polymerase chain reaction (PCR), and the cAMP levels were detected by using enzyme-immunoassay method.

RESULTS(1) On the 28th day PI, the mRNA expression of BDNF in brain white matter and spinal cord of rats in ZGP and YGP groups were up-regulated, especially in YGP group (P<0.05 or P<0.01). (2) On the 14th day PI, the cAMP levels in brain white matters significantly increased in PA and YGP groups compared with MO group (P<0.05 or P<0.01), and the cAMP level in YGP group was higher than that in ZGP group (P<0.05). The cAMP level in spinal cord also significantly increased in YGP group compared with MO, PA and ZGP groups, respectively (P<0.01). (3) On the 14th day PI, the PKA expression in spinal cord of rats in ZGP group was significantly decreased compared with MO and YGP groups, respectively (P<0.05). (4) On the 28th day PI, there was a positive correlation between cAMP and PKA expression in the brain white matter of YGP rats.

CONCLUSIONSThe results suggest that ZGP and YGP may promote axonal regeneration by modulating cAMP/PKA signal transduction pathway, but the targets of molecular mechanism of ZGP may be different from those of YGP.

Objective: To determine the serotypes and drug resistance profiles of Shiga toxin-producing Escherichia coli (STEC) in animal stools from the Weishan area in Shandong Province, China. To provide the basis for further study. Methods: Five hundred animal stool samples (from pigs, cattle, sheep, dogs and birds) were collected from the Weishan area and STEC strains were isolated from these samples. Strains were serotyped by a serum agglutination test, and their drug resistance profiles were determined through antimicrobial sensitivity experiments. In this study, PCR was used to detect tetracycline resistance genes (tetA, tetB, tetC, tetD) and beta-lactam resistance genes (blaSHV-1, blaCTX-M, blaTEM). Results: Sixteen strains of STEC were isolated from animal stool samples. Thirteen strains were isolated from pig stool samples, two from bovine stool samples and one from a sheep stool sample. Two of the strains were identified as E. coli O157:H7, and other 14 strains were non-O157 STEC of different serotypes. Antimicrobial sensitivity experiments showed that 15 of the strains were multidrug resistant. The rates of resistance were as follows: nalidixic acid (12/16 strains), sulfisoxazole (11/16), trimethoprim and sulphame-thoxazole (11/16), doxycycline (9/16), azithromycin (9/16), tetracycline (9/16), chloramphenicol (8/16) and streptomycin (8/16). Therefore, nalidixic acid showed the highest rate of resistance among the strains, followed by trimethoprim and sulphame-thoxazole, and sulfisoxazole. Resistance to cefepime or imipenem was not detected. In total, three types of drug resistance genes (tetA, tetB and tetC) were detected among the 16 strains. Conclusion The results showed that STEC strains isolated from animals in the Weishan area were of a range of serotypes. The 16 strains of STEC isolated from animal stools in this area were resistant to a number of antibiotics, with many strains displaying multidrug resistance.

Objective To study the molecular-biologic characteristics and epidemiological status of iatrogenic related Community-acquired methicillin-resistant Staphylococcus (S.) aureus (CA-MRSA) in China through Meta-analysis.Methods Data through systematic searching for peer-reviewed articles published before December 3rd,2015 from 4 main electronic databases including China National Knowledge Infrastructure (CNKI),Wanfang Data,PubMed and Web of Science Core Collection was collected,for this Meta-analysis.PRISMA guidelines were followed and the proportion of MRSA,CA-MRSA,hospital-acquired MRSA (HA-MRSA) and panton-valentine leucocidin (PVL) gene in certain populations were quantitatively analyzed by Stata 13.0 software.Results Average proportion of CA-MRSA from S.aureus was 12％ (95％CI:8％-16％).CA-MRSA in MRSA was 18％ (95％CI:12％-24％).42.1％ (95％CI:20.4％-63.7％) of the CA-MRSA carried a PVL gene,and the number was higher than general MRSA (t =-2.99,P=0.011).Conclusion CA-MRSA was in lower proportion than HA-MRSA,both seen in general MRSA and in S.aureu.s,but under higher proportion of carrying the PVL gene.Transmission of CA-MRSA could be prevented within the general population through conducting effective surveillances and preventive programs.
