Objective To observe the effect of electroacupuncture at thoracic Jiaji points (EX-B 2) on the Behavior Measurement Scale (BMS) score, and expressions of nestin and glial fibrillary acidic protein (GFAP) in spinal cord in mice after spinal cord injury, and to explore the action mechanism of electroacupuncture in protecting nerves and recovering motor function.Method Ninety-six female C57BL/6 mice were randomized into a sham operation group, a spinal cord injury group, an electroacupuncture group, and an acupuncture group, 24 mice in each group. Except for the sham operation group, spinal cord injury at T9 level was induced in the other three groups. The electroacupuncture group was intervened by electroacupuncture at Jiaji points (EX-B 2) of T7 and T11, and the acupuncture group received manual acupuncture at the same acupoints. The intervention was conducted 15 min each time, once a day, with 1 d interval every 5 d, for a total of 28 d. The BMS score was evaluated respectively after 3 d, 7 d, 14 d, and 28 d intervention. Enzyme-linked immunosorbent assay (ELISA) was adopted to detect the expression ofnestin in spinal cord, and immunofluorescence and Western blotting were used to detect the expression of GFAP in spinal cord.Result Respectively 14 d and 28 d after spinal cord injury, the main and auxiliary scores of BMS in the acupuncture group were significantly higher than those in the spinal cord injury group (P<0.05); 28 d after spinal cord injury, the main and auxiliary scores of BMS in the acupuncture group were significantly higher than those in the spinal cord injury group (P<0.05) and the auxiliary BMS score in the electroacupuncture group was significantly higher than that in the acupuncture group (P<0.05). Respectively 3 d, 7 d, and 14 d after spinal cord injury, the contents of nestin in the electroacupuncture group were obviously increased and significantly different from those in the spinal cord injury group (P<0.05). The nestin content of the acupuncture group was significantly higher than that of the spinal cord injury group 7 d and 14 d after spinal cord injury (P<0.05). The expression of GFAP in the electro-acupuncture group was significantly higher than that in the spinal cord injury group 3 d and 7 d after spinal cord injury (P<0.05); the inhibitions on the immunoreactivity of GFAP in the electroacupuncture group and acupuncture group were more significant than the inhibition in the spinal cord injury group 28 d after the injury (P<0.05).Conclusion Electroacupuncture at Jiaji points (EX-B 2) can promote the recovery of motor function after spinal cord injury, which is related to the enhancement of the expressions of nestin and GFAP within 7 d after the injury, and the two expressions are in a positive correlation. In the early stage of treatment, electroacupuncture can boost the activity of astrocytes to act as neural stem cells and inhibit the immunoreactivity of GFAP in the later stage to benefit the reconstruction of neurologic function.

AIM:By optical coherence tomography to observe macular thickness change characteristics and foveal images of patients with retinitis pigmentosa (RP).METHODS: From September 2014 to September 2016, 74 patients (148 eyes) with retinitis pigmentosa diagnosed in our hospital were selected, and 50 healthy subjects (100 eyes) as normal controls;two groups received optical coherence tomography and fundus camera detection.The images of the macular were obtained to observe and measure the thickness of the macular fovea and at 4mm temporal side, the center of papillo macular bundle.RESULTS:The results showed that: the thickness of the macular fovea and at 4mm temporal side of RP patients were the same as normal controls without statistically significant(P>0.05);the thickness of the center of papillo macular bundle was less than that of normal control with statistically significant (P<0.05).There were five types characteristics in OCT imges in RP patients: macular edema in 19 patients 38 eyes;retinal pigment epithelium and choroidal capillary thinning in 18 patients 36 eyes;retinal pigment epithelium atrophy in 12 patients 24 eyes;normal in 12 patients 24 eyes;different thickness of pigment epithelium layer in 13 patients 26 eyes.CONCLUSION: Optical coherence tomography (OCT) can be used to detect the macular lesions in a timely manner, to help understanding the development of the disease, and provide the clinical basis for the early diagnosis and treatment of patients.

The research procedure of dynamic data acquisition and analysis system for body temperature(the body temperature HOLTER) is introduced in this paper.Some aspects of software and hardware technology related to the body temperature HOLTER are discussed emphatically.The system presents a good result through the preliminary application to the clinical practice.

This paper introduces a ultra-low frequency modulated low frequency pulse transcutaneous neuromuscalar electrical stimulator.Through clinical practices,it has shown very satisfactory results.

OBJECTIVE:To strengthen the supervision of drug stocktaking,and to improve drug management. METHODS:The data of drug stocktaking were extracted from our hospital from 2011 to 2014,and was analyzed in respects of accounts coinci-dence rate,drug profit and loss account rate,the entry and exit account between departments and original record,etc. A series of supervision strategies were established,and the data of drug stocktaking was analyzed during Jan.-Jun. in 2015 statistically to evalu-ated supervision effects. RESULTS:The supervision of drug stocktaking was strengthened through limiting the right of drug profit and loss on stocktaking,strengthening original stocktaking record management,establishing Key Drug List,setting up drug stock-taking supervision institutions,etc. During Jan.-Jun. in 2015,there was obvious improvement in the drug supervision skills,in terms of account coincidence rate,profit and loss account,material safety,cash flow rate,staff responsibility and stocktaking dura-tion,etc. More specially,the accounts coincidence rate had rose from about 82.8% to more than 95%;both the key drug accounts coincidence rate and the entry and exit account between departments coincidence rate had reached to 100%;the profit and loss ac-count rate had reduced from about 7.6% to less than 0.3%;the stocktaking time had reduced from 10 h to 3 h. CONCLUSIONS:Strengthening drug stocktaking supervision can not only improve the stocktaking efficiency and quality markedly,but also contrib-utes to the development of other pharmacy work in hospital.

The host protein SAMHD1 has been identified as the first mammalian deoxynucleoside triphosphate triphosphohydrolase (dNTPase), which blocks the infection of HIV-1 in non-cycling immune cells.SAMHD1 protein is highly expressed in human myeloid-lineage cells and resting CD4+T lymphocytes, which restricts HIV-1 replication by hydrolyzing the cellular dNTPs, thus inhibiting reverse transcription and viral complementary DNA ( cDNA) synthesis. Recent studies have revealed that SAMHD 1 plays an important role in virus whole life by promoting HIV -1 genome recombination, degenerating viral genome RNA and restricting virus transmission between cells .In this review, these progress on SAMHD1 research are summarized and the mechanisms by which SAMHD 1 mediates retroviral restriction are analyzed .
