OBJECTIVE:To study the effects and mechanism of rapamycin on invasion and metastasis of cervical cancer HeLa cell. METHODS:HeLa cells were divided into control group and rapamycin low-dose,medium-dose and high-dose groups (10, 30,100 nmol/L). After treated for 48 h,cell viability was measured by MTT assay,and inhibitory rate was calculated;migration and invasion of cell was tested by Transwell assay. The expression of matrix metalloproteinase 2(MMP-2),MMP-9,Vimentin and E-cadherin,and phosphorylation of protein kinase B (Akt),mammalian target of rapamycin (mTOR) were detected by Western blot. RESULTS:Compared with control group,the inhibition rate of cell viability was increased in rapamycin groups(P<0.01);the number of invasion and metastasis cells decreased(P<0.01);the expression of MMP-2,MMP-9 and Vimentin were decreased (P<0.01 or P<0.05);the expression of E-cadherin was enhanced(P<0.01 or P<0.05);the phosphorylation of Akt and mTOR were reduced (P<0.01). CONCLUSIONS:Rapamycin could inhibit invasion and metastasis of HeLa cell via Akt/mTOR signal pathway.

Xanthine oxidase (XOD), catalyzing purine metabolism, is the key enzyme in uric acid (UA) biosynthesis, and becomes an important target for hyperuricemia treatment. The inhibition on XOD plays an important role in the treatment of hyperuricemia-related diseases, such as gout, as well as oxidative stress-induced tissue injury. Here, studies on the natural products with XOD inhibition are reviewed.

The object of this study is to preparate the berberine hydrochloride (BBH) resin compound with taste masking effect. We took the BBH as the model drug and Amberlite IRP69 as the drug carriers, uncovered the curve of solubility of BBH in different cosolvent with a certain range of temperature, and then used it to calculate the parameters during the preparation of the complex such as adding quantity of BBH and the reaction temperature. Afterwards, the characteristic and in vitro release experiments were studied to verify the formation and predict the in vivo release behavior of the complex. The results showed that in the condition of using 60% ethanol as a cosolvent and stirring at 50 ℃ for 1 h, the drug loading and drug availability of the complex are at about 35% and 64%, respectively, and has a better taste-masking effect. In this study, a method was provided for preparing a taste-masking preparation of BBH.

OBJECTIVETo compare therapeutic effects between unilateral decompression technique only and open decompression technique with fusion and internal fixation for the treatment of lumbar spinal stenosis.

METHODSFrom March 2008 to February 2011, 82 patients with lumbar spinal stenosis were treated with operations, and divided into two groups. There were 13 males and 19 females in group A, with a mean age of (56.31±4.31) years old. The patients in group A were treated with unilateral decompression via fenestration technique only, including 23 patients obtaining single level decompression and 9 patients obtaining two levels decompression. In group B, there were 18 males and 32 females, with a mean age of (57.53±4.28) years old. The patients in group B were treated with open decompressive technique with fusion and internal fixation, including 38 patients obtaining single level decompression and 12 patients obtaining two levels decompression. The VAS of back pain and leg pain, ODI were recorded before and after surgery to evaluate low back pain,leg pain and walking tolerance.

RESULTSAll the patients were followed up, and the duration ranged from 10.9 to 43.4 months,with a mean of 32.8 months. There were no differences in age, stenosis level, VAS of back and leg pain and ODI before surgery between two groups. Compared with the corresponding ones in group B, the operation time, blood loss, hospitalization time,recovery time of routine daily life and finacial expenditure of patients were all shorter or less in group A. There was no statistically difference in complications between two groups.

CONCLUSION"Unilateral decompression via fenestration technique" is a less invasive and more effective decompressive technique for degenerative spinal stenosis without posterior elements damage. It has advantages in operation time, blood loss, hospitalization time, recovery to daily life and financial expenditure. When controlling the operative indications strictly, the technique could be an important procedure for surgical treatment of degenerative spinal stenosis, especially in the elderly population.

Commercial production of bioethanol from lignocellulosic hydrolysates requires efficient fermenting strains. The abilities of the strain to converting all types of sugars in the hydrolysate to ethanol in high yield and to effectively tolerating/metabolizing inhibitors are necessary. Genome shuffling is a novel method for breeding, and it has been applied in pharmaceutical and food industry. This review summarized the technique of genome shuffling including principle, process, applications and its prospect for strains improvement in ethanol production from lignocellulosic hydrolysates.

Objective To investigate the expression and clinical significance of p63, CD_(44v6) and human papilloma virus (HPV) 16/18 in carcinoma of cervix and precancerous lesion and to study their role in the pathogenesis of the infiltrative carcinoma of the cervix(ICC). Methods 145 patients were selected, among whom were 60 cases of ICC, 55 cases of cervical intraepithelial neoplasia (CIN) and 30 cases of normal cervical epidermis (NCE). Immunohistochemistry streptavidin peroxidase (SP) was used to detect the expressions of p63 and CD_(44v6) protein and hybridization in situ was used to measure HPV 16/18 gene on tissue microarray. Results HPV 16/18, p63 and CD_(44v6) in ICC were significantly higher than those in CIN and NCE groups (P < 0.05). The expressions of HPV 16/18 gene in CIN I 、CIN II and CIN III were 27.3 % , 43.8 %, 70.6 % respectively. p63 protein was mainly expressed in squamous cell carcinoma, but not in adenocarcinoma. p63-positive rate was related to the grade of squamous cell carcinoma and clinical stage. CD_(44v6) positive rate was related to the pathological grade and clinical stage. Moreover, the positive rate of lymph node metastasis was significantly higher than the cases without metastasis (P <0.05). The expression of HPV16/18 was positively correlated with that of p63 in ISCC (P <0.05, Cp =0.49). Conclusion HPV16/18 possibly participate in the pathogenesis and progress of cervical squamous carcinoma. p63, as the cancer gene, may participate in the occurrence and development of cervical cancer caused by HPV 16/18. p63 could be a differentiation indicator of cervical squamous carcinoma, and it could be one of the markers which would be differentiated into squamous cell in malignant tumour. CD_(44v6) could be used as one of the indicators of distant metastasis of cervical cancer.

Background Congenital fibrosis of extraocular muscles (CFEOM) affects patient' s appearance and quality of life,and no effective treatment for this disease is available.Imaging study is helpful for exploring the pathogenesis of CFEOM.Objective This study was to describe the characteristics of CFEOM associated with limb movement disorder using magnetic resonance imaging (MRI).Methods A family with CFEOM associated with limb movement disorder was investigated in Renmin Hospital of Wuhan University.Disease history was collected and the pedigree was investigated.Ophthalmologic examinations,including corrected visual acuity,refractive error,slitlamp examination,ophthalmoscopic examination,force of levator palpebrae superioris,ocular movement,eye position,forced duction test,and bell phenomenon examination,were performed.Ocular orbital and cranial MRI was performed in 4 CFEOM patients and 10 normal subjects to compare the structures of the extraocular muscles,motor nerve and cranium.Oral informed consent was obtained from each patient prior to any medical examination.Results A total of 1 1 members from 3 generations were investigated in this study,presenting with 4 cases of disease.The mode of inheritance of this family complied with the Mendelian autosomal dominant inheritance law.Clinical signs included disturbance of eye movement,deviation of eye position,ptosis,lack of Bell sign and positive reaction of passive pull test.In addition,unstable gait,improper body limb alignment,dysphasia and mental retardation were ohserved in 1 patient,which coincided with the diagnostic criteria of type 3 CFEOM.MRI results demonstrated that the levator palpebrae superioris,superior rectus and superior oblique muscle were clearly thinner,and the medial rectus,lateral rectus,inferior rectus muscle were thinning in the patients,showing significant differences in comparison with the normal controls(P＜O.05).The oculomotor and abducens nerves became thinner and even absent in the patients.Cranial MRI showed that Ⅲ-3 in the pedigree with callosum was shorter than that of the normal controls,suggesting that patient suffered from corpus callosum hypoplasia.Meanwhile,cranial MRI indicated the presence of cerebellar hypoplasia and the expansion of the fourth ventricle.Conclusions MRI demonstrates consistent abnormalities of the oculomotor nerves and abducens nerves in the affected individuals in this CFEOM 3 family,and some affected members exhibit two types of central nervous system abnormalities-corpus callosum and cerebellar hypoplasia.These findings suggest that CFEOM 3 is primarily a neuronal disease.
