Retinitis pigmentosa (RP) is a hereditary disease characterized by the progressive loss of photoreceptor cells. Disease pathology primarily affects rod photoreceptor cells first but light-insensitive cone photoreceptor bodies can survivor longer. Delivered by adeno-associated viral vector or lentiviral vector, expression of microbial-type rhodopsin, channelrhodopsin-2 or archaebacterial halorhodopsin in the survived retinal cells can substitute for the native phototransduction cascade in mouse models of retinitis pigmentosa. It can also restore light sensitivity and activate all retinal cone pathways and drive sophisticated retinal circuit functions. Thus, expression of channelrhodopsins or halorhodopsin might be a potential strategy for the restoration vision of patients with RP.

ObjectiveTo evaluate the efficacy of preoperative oral pregabalin for attenuating postoperative pain after laparoscopic cholecystectomy.MethodsIn this prospective,randomized controlled double-blind study,sixty ASA Ⅰ or Ⅱ patients aged 19-72 yr weighing 46-86 kg undergoing laparoscopic cholecystectomy were randomly divided into 2 groups ( n =30 each):control group (group C) received placebo,and pregabalin group (group P) received oral pregabalin 150 mg 1 h before surgery.Anesthesia was induced with propofol,fentanyl and rocuronium and maintained with sevoflurane inhalation and intermittent iv boluses of fentanyl and rocuronium.The patients were intubated and mechanically ventilated.BIS value was maintained at 40-50 during operation.Static and dynamic VAS score,Ramsay score and consumption of morphine were recorded at 6,12,and 24 h after surgery.Side-effects including nausea,vomiting,headache and dizziness were also recorded.ResultsStatic and dynamic VAS scores and morphine consumption were significantly lower during the first 24 h after surgery while Ramsay scores were higher at 6 h after operation in group P than in group C.There was no significant difference in the incidence of side-effects between the 2 groups.No over-sedation occurred in group P.ConclusionPreoperative oral pregabalin 150 mg is safe and effective in reducing postoperative pain after laparoscopic cholecystectomy.

Objective To observe the differences of cerebral activation pattern with resting state functional magnetic resonance imaging (rs-fMRI) between patients with spasmodic torticollis (ST) and healthy controls,thus to investigate the pathogenesis of ST.Methods Nineteen ST patients and 21 age,sex and education-matched healthy controls,recruited from the Department of Neurology,First Affiliated Hospital of Guangxi Medical University between November 2012 and January 2016,were included in this study.rs-fMRI and factional amplitude of low frequency fluctuation (fALFF) were used to obtain differences between patients with ST and healthy controls,and correlative analysis was made on fALFF values of abnormal brain regions and ST patients' symptom severity (Tsui scores).Results Compared with healthy controls,patients with ST had significantly increased fALFF in the left cerebellum and significantly decreased fALFF in the left posterior cingulate cortex/precuneus,right posterior cingulate cortex/precuneus,left middle temporal gyrus,right angular gyrus,left post-central gyrus,right supplementary motor area (t =-5.714-5.920,P <0.01),and abnormal brain regions' fALFF values had no correlation with patients' age of onset,disease course,symptom severity (P > 0.05).Conclusion Abnormal sensorimotor area,default mode network and cerebellum dysfunction may play a role in the pathophysiology of ST.

BACKGROUND:Cel co-culture can maximize the simulation ofin vivomicroenvironment. Cel scratch test and interleukin-1β can destroy the balance between matrix metaloproteinases (MMPs) and matrix metaloproteinase inhibitors (TIMPs), resulting in extracelular matrix degradation of the articular cartilage, functional disorders of chondrocytes and articular cartilage degeneration. OBJECTIVE:To study the effect of interleukin-1β on migration, MMP and TIMP expression of chondrocytes co-cultured with osteoblast supernatantin vitro. METHODS:There were three groups: chondrocyte monoculture group, osteoblast+chondrocyte group (co-culture group), osteoblast+chondrocyte+interleukin-1β group (interleukin-1β group). Cel scratch test was conducted to observe the migration of chondrocytes within 24 hours. Semi-quantitative PCR test was used to detect the changes in expressions of MMP-1, MMP-2, MMP-3, MMP-9, TIMP-1, TIMP-2, TIMP-3, TIMP-9 in chondrocytes within 24 hours. RESULTS AND CONCLUSION:Compared with the monoculture group, cel migration rate of the other two groups were increased significantly (P< 0.01). Compared with the monoculture group, the gene expressions of MMP-1, MMP-2, MMP-3 and MMP-9 were increased significantly in the coculture group (P < 0. 05); the gene expressions of MMP-1, MMP-3, MMP-9 were increased significantly in the interleukin-1β group (P< 0. 01). Compared with monoculture group, the gene expression of TIMP-1 was increased significantly (P < 0. 01), but the gene expressions of TIMP-3 and TIMP-4 were declined significantly (P < 0. 05) in the other two groups. These findings indicate that co-culture of chondrocytes with osteoblasts can promote chondrocytes migration, enhance gene expression of chondrocytes MMP-1, MMP-2, MMP-3, MMP-9 and regulate gene expression of TIMPs family. Interleukin-1β inhibitsthe migration of chondrocytes co-cultured with osteoblasts and gene expression of TIMPs family.

Objective To study the effect of genetic polymorphism of leukotriene C4 synthase (LTC4S) and 5-lipoxy-genase (ALOX5) on efifcacy of leukotriene receptor antagonist (LTRA) in children with moderate persistent asthma. Methods Seventy-two children with moderate persistent asthma who visited the out-patient clinic of Shanghai Children’s Medical. Center from June 2011 to June 2013 were divided into two groups, each of which ifrst had ICS or LTRA+ICS for twelve weeks and then had the other for another twelve weeks. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to assess the genetic polymorphism of LTC4S RS730012 and ALOX5 RS2115819. Pulmonary function, clinical symptoms and C-ACT score were evaluated before and after treatment. Results After the treatment with LTRA, 75%forced expiratory lfow (FEF75) was improved more signiifcantly in patients with A/C or C/C genotype at LTC4S (RS730012) locus than in patients with A/A genotype. After the treatment with LTRA+ICS, there was no difference of pulmonary function among patients with different genotypes at ALOX5 (RS2115819). Conclusions The SNP of LTC4S (RS730012) is associated with the efifcacy of montelukast in asthmatic patients because of the improvement of small airway function.

One hundred and twenty-two infertile women with polycystic ovary syndrome (PCOS) and 112 infertile women without PCOS were interviewed with symptom checklist 90 ( SCL-90) and questionnaire of demographic and clinical characteristics to understand their psychological health status. Results demonstrated that scores of depression, interpersonal sensitivity, obsessive-compulsive and aggressive symptoms in infertile patients with PCOS were significantly higher than those in non-PCOS infertile ones (P < 0. 05 ). Acne had negative effect on their psychological health status (OR =3. 379, 95% CI = 1.096 ±10.419) . Scores of somzatization, interpersonal sensitivity, anxiety, obsessive-compulsive, aggressive and paranoid ideation symptoms were significantly higher in secondary infertile patients with PCOS than those in primary infertile ones (P<0. 05). Patients with PCOS had obviously psychological problems, especially in secondary infertile patients with PCOS ( P < 0. 05 ). Thus, it is suggested that psychological health status be evaluated in clinical diagnosis for infertile women so that they can be predicted and treated to improve its effectiveness.
