Journal of Acupuncture and Tuina Science 2010;08(4):249-252
Objective: To study the clinical effect of acupuncture combined with methylcobalamin in the treatment of diabetic peripheral neuropathy. Methods: Seventy-five diabetic patients complicated with peripheral neuropathies were included and randomly allocated into a treatment group (40 cases) and a control group (35 cases). The patients in the treatment group all received acupuncture therapy plus methylcobalamin. In the control group, patients only received methylcobalamin for treatment. The therapeutic effect was evaluated 4 weeks later. Results: Both of the two groups presented improvement in nervous symptoms, signs and nerve conduction, and the improvement of the treatment group was significantly better than that of the control group (P<0.05). Conclusion: The therapy of acupuncture in combination with methylcobalamin is more effective than the monotherapy with methylcobalamin in the treatment of diabetic peripheral neuropathy.

Chinese Journal of Endocrinology and Metabolism 2017;33(6):502-505
To explore the detection of GNAS1 gene mutation from peripheral blood and non-involved bone marrow in patients with fibrous dysplasia of bone(FD). Both peripheral blood and non-involved bone marrow collected from six FD patients were used for genetic diagnosis by next generation sequencing and direct sequencing respectively. Two patients were found to have common gene mutation(positive) by next generation sequencing, accounting for 33.3% of total six people: p.R201H(CGT>CAT) was detected in both peripheral blood and bone marrow of patient No.3, and p.R201C(CGT>TGT) was detected in both tissues of patient No.6. While direct sequencing only found p.R201H(CGT>CAT) mutation in peripheral blood and bone marrow of patient No.3. Detection of GNAS1 gene mutation may contribute to the diagnosis of FD. Hot spot mutations of GNAS1 are present in peripheral blood and non-involved bone marrow samples from some Chinese FD patients, but the diagnostic value and sensitivity of GNAS1 gene mutation in non-involved tissues of FD patients is low by next generation sequencing or direct sequencing.
5.Observation of postoperative analgesic effects of intravenous parecoxib in gerontal patients undergoing laparoscopic cholecystectomy
Chinese Journal of Geriatrics 2011;30(8):654-656
Objective To observe the postoperative analgesic effects of perioperative intravenous parecoxib in gerontal patients undergoing laparoscopic cholecystectomy. Methods A prospective,randomized, double-blind, placebo-controlled, parallel group study was performed. The 40 American Society of Anesthesiologists (ASA) Ⅰ or Ⅱ patients (aged 60-80 years) undergoing elective laparoscopic cholecystectomy under general anesthesia were randomly allocated to 2 groups (n = 20,each): the parecoxib group received intravenous parecoxib 40 mg at 10 minutes before incision and 12 hours and 24 hours after incision; however, the placebo group received 5 ml normal saline instead of parecoxib at the same time. The intensity of algesia was measured using visual analogue scale (VAS)scores (1-10, 0 = no pain, 10 = worst pain), and was recorded at 2, 4, 6, 12, 24 hours after operation. The patients' global evaluation of postoperative analgesia was recorded and compared between the two groups. Results The VAS scores at the different time points were significantly less in parecoxib group than in placebo group (all P< 0.05). The patients' global evaluation of postoperative analgesia was higher in parecoxib group than in placebo group [(8. 1 ± 1.2) scores vs.(5.2± 0. 9 ) scores, t = 7. 402, P < 0. 05]. Conclusions Intravenous parecoxib can effectively relieve postoperative algesia and improve postoperative analgesia after laparoscopic cholecystectomy.

7.Fatigue in Parkinson's disease: a review
Chinese Journal of Geriatrics 2016;35(4):438-443
Parkinson's disease (PD) is a common neurodegenerative disorder with typical motor symptoms and a variety of non-motor symptoms,including neuropsychiatric symptoms,autonomic dysfunctions,abnormal sense,sleep disorders and fatigue.Studies showed that several non-motor symptoms,such as olfactory dysfunction,constipation,rapid eye movement sleep behavior disorder,depression and fatigue,can occur before the onset of motor symptoms.Fatigue has been considered as one of the most disabling symptoms,and it has a significant impact on activity of daily living and quality of life,and brings heavy burdens to caregivers.However,fatigue in PD has no special biomarkers,so clinicians are lack of the recognition and intervention.Here,we will expound the prevalence,risk factors,rating scales and potential mechanism relating to neuropathology,neuroinflammation and neurobiochemistry in PD patients with fatigue.
8.Advance in The Flowering Time Control of Arabidopsis
Progress in Biochemistry and Biophysics 2006;0(04):-
Flowering is one of the most important progresses for most plants during the transition from vegetative growth to reproductive growth. There are many factors that affect the flowering, including two main external factors, light and temperature, and the internal factors such as gibberellin acid (GA) and autonomous elements. At present, the late-flowering mutants are fallen into four pathways: photoperiod pathway, vernalization pathway, autonomous pathway and GA pathway according to factors described above. Through several floral integrators, such as SOC1, FT and LFY, the multiple flowering regulatory pathways control the flowering finely under the variable environmental condition and physiological condition.
9. Effect of phosphorylated-ERK1/2 on NF-κB p65 expression in substantia nigra of mice with MPTP-induced Parkinson's disease
Academic Journal of Second Military Medical University 2011;32(11):1176-1180
Objective To mvestigate the effect of phospholated-ERKl/2 on NF-κB p65 expresson nn the substania nigra(SN) of l-msthyi-4-phenyi-l,2, 3, 6-tetrahydropyeidine (MPTP)-induced mouse model of Parkinson's disease(PD). Methods PD mouse model was induced by MPTP and the behavoor of mouse was observed. Immunohistochemistry and Western bloiting analysis were used to observe the changes in expression of tyrosine hydroxylase (TH), NF-κB p65 and p-ERKl/2 in the SN of midbrain. Meanwhite, the above changes were also observed after treatment with U0126, a specific inhibitor of ERK. Results 1 h after the third MPTP administration, there were much more p-ERKl/2 positive cells than NF-κB p65 positive cells in the SN. 24 h after the fifth injection of MPTP, NF-κB p65 positive cells were significantly increased and p-ERKl/2 positive celiswere decreased, accompanted by marked loss of TH positive neurons. The above changes were greatly alleviated in animais treated with U0l26. Conclusion ERKl/2 pathway may regulate NF-κB p65 activation in MPTP-induced mouse model of Parkinson's disease, which leads to loss of dopamine neurons.

Background Light leads to the damage of retinal function and structure by promoting the reproduction of radicals and lipid peroxides when retina is exposed to an intense light environment for a long time.It is necessary to study how to protect the retina against light-induced injury in ophthalmology.Objective The aim of this study was to evaluate the effect of anthocyanidin extracts in preventing retinal photic damage.Methods Eighteen clean male Sprague-Dawley (SD) rats were randomly assigned to normal saline group,anthocyanidin group and mixed (hydrogen-rich saline (HRS) + anthocyanidin,1:1 in volume) group and 6 rats for each.The electroretinogram (ERG) with international standardized 5 items was recorded from all the rats before experiment.Normal saline,anthocyanidin extracts or mixed solution of 5 ml/kg were intraperitoneally injected in the three groups,respectively,for consecutive 5 days.Then the diffused light with the luminance intensity of (5000±300)lx was used to irradiate the right eyes of the rats for consecutive 3 hours during 19:00 through 7:00 in a device made by our laboratory,and the left eyes were covered at the same time.The ERG was repeatedly recorded 5 days after light irradiation.The rats were sacrificed at the end of the experiment and retinal sections were prepared for the histopathological examination.The functional and structural changes of retinas were compared among the different groups.The use of the rats followed the Statement of ARVO.Results The differences of rat body weight were not statistically significant among the three groups (before experiment:F =0.472,P =0.841 ; after experiment:F =0.658,P=0.762).No any significant difference was found in scotopic 0.01 ERG b wave,scotopic 3.0 ERG a and b waves,scotopic 3.0 oscillatory potentials,photopic 3.0 ERG b wave and 3.0 flicker P1wave between the left eyes and the right eyes in the three groups before experiment (P>0.05).The amplitudes of various waves of ERG were significantly declined in the right eyes compared with the left eyes (P<0.05).The mean differential values of scotopic 0.01 ERG b wave,scotopic 3.0 ERG a and b waves,scotopic 3.0 oscillatory potentials were significantly different(F =4.594,P=0.029; F=3.834,P=0.037; F=12.823,P=0.000; F=3.976,P=0.032),but those in photopic 3.0 ERG b wave were not statistically significant (F =1.488,P =0.259).Compared with the normal saline group,the differential values of scotopic 0.01 ERG b wave,scotopic 3.0 ERG a and b waves,scotopic 3.0 oscillatory potentials were all reduced in the anthocyanidin group and mixed group (P < 0.05).The cells of outer nuclear layer were decreased in the right eyes in the three groups compared with the left eyes,especially around the optic nerve head and the upside of the retina,with significant differences between them (P<0.05),and those in the anthocyanidin group and mixed group were significantly less than normal saline group (P<0.05).Conclusions Anthocyanidin has a protective effect on light-induced retinal damage of SD rats.The protective effect of anthocyanidin extracts is similar to the integrated effect of the mixed group.
