RESUMEN
OBJECTIVE：To study the effect s of Bifidobacterium combined with L-carnitine on intestinal flora of dysbacteriosis diarrhea model rats. METHODS ：Totally 30 SD rats were randomly divided into blank control group ，model group ，probiotics group（Bifidobacterium triple viable enteric coated capsules 70 mg/mL），L-carnitine group （L-carnitine injection 50 mg/mL）and L-carnitine+probiotics group （L-carnitine injection 50 mg/mL+Bifidobacterium triple viable enteric coated capsules 70 mg/mL）. Except for blank control group ，the rats in other groups were given 50 mg/mL clindamycin phosphate intragastrically （2 mL/rat， once a day ，for 4 consecutive days ）to establish the model of dysbacteriosis diarrhea. On the 5th day of the experiment ，the rats in administration groups were given corresponding drugs intragastrically ，blank control group and model group were given equal volume of normal saline intragastrically ；with the dosage volume of 1 mL/rat，once a day ，for consecutive 7 days. The general situation of rats in each group was observed during the experiment. The feces of normal control group and model group at the end of the modeling and the feces of the rats in administration group after the last administration were collected for genomic DNA extraction，polymerase chain reaction amplification ，library construction and high-throughput sequencing. After processing ，the effective data were analyzed by operational taxonomic unitsclustering and species annotation ，as well as Alpha and Beta diversity of compared with blank control group ，grade 1 feces and grade 2feces were found in model group. The diversity and richness of intestinal flora ，the ratio of Firmicutes/Bacteroidetes and zhongjuanwang7@163.com the abundance of probiotics such as Lactobacillus， Bifidobacterium and Ackermann were significantly decreased （P＜0.05），while the abundance of pathogenic bacteria such as Enterococcus was significantly increased （P＜0.05）. At the end of the recovery period ，compared with model group ，the activity，fecal morphology and color of rats in probiotics group ，L-carnitine group and L-carnitine+probiotics group returned to normal，and the diversity and richness of intestinal flora had no significant difference （P＞0.05）. However ，the abundance of Lactobacillus in intestinal tract was increased to a certain extent ，and the abundance of Ackermann in intestinal tract of rats in L-carnitine+probiotics group was significantly increased （P＜0.05）. CONCLUSIONS ：Although Bifidobacterium combined with L-carnitine have no significant effect on improving the diversity and richness of intestinal flora in dysbacteriosis diarrhea model rats，it could increase the abundance of probiotics to a certain extent.
RESUMEN
Under the background of the innovative medical association, the company took the lead in promoting the senior nurses to the community hospitals in Anhui, and opened community nursing clinics to better implement the graded diagnosis and treatment system and meet the needs of residents' integrated health services. From the background of a new round of medical reform, this paper analyzes the new occupational orientation of senior nurses in the innovative medical association model, and introduces and analyzes the problems that arise in the exploration stage of the sinking community, and puts forward suggestions based on the actual situation.

RESUMEN
BACKGROUND:At present, the internal fixation and fusion surgical treatment of lumbar degenerative disease tends to diversify, but posterior lumbar interbody fusion within a single bilateral pedicle screw fixation is stil common in clinical practice; the two ways after treatment can achieve satisfactory clinical efficacy, but which way has advantages is stil controversial. OBJECTIVE:To evaluate the efficacy and safety of unilateral and bilateral pedicle screw fixation and single segment lumbar interbody fusion in the repair of lumbar degenerative disease by a meta-analysis system. METHODS: According to the Cochrane Colaboration search strategy, we searched MEDLINE, PubMed, EMBASE, CBMdisc, CNKI, VIP and WanFang Data. Randomized controled trials concerned unilateral and bilateral pedicle screw fixation and single segment lumbar interbody fusion in the treatment of lumbar degenerative diseases. By two reviewers, in strict accordance with inclusion and exclusion criteria, literatures were screened, data were extracted, and the methodology quality of included trials was criticaly assessed. RevMan5.1 software was used for meta-analysis. RESULTS AND CONCLUSION: Six randomized controled trials involving 507 patients were included. The results of meta-analysis showed that fixed unilateral and bilateral pedicle screw between single lumbar fusion and surgery in the treatment of lumbar degenerative diseases, significant differences were detected in surgical time [WMD=-40.29, 95% CI (-43.79, -36.79)], intraoperative blood loss [WMD=-74.13, 95%CI (-86.13,-62.13)], length of hospital stay [WMD=-1.04, 95%CI (-1.30,-0.79)], final folow-up Visual Analogue Scale score [WMD=0.33, 95% CI (0.24, 0.42)], final folow-up Oswestry dysfunction index [WMD=-1.07, 95%CI(-1.57, -0.56)]; unilateral side was better than bilateral side (P < 0.000 1). There was no significant difference in complication rate [RR=0.54, 95% CI(0.25, 1.17)] and fusion rate [RR=0.53, 95%CI (0.22, 1.28)] (P=0.12 andP=0.16). These results suggested that unilateral and bilateral pedicle screw fixation and single lumbar fusion in the treatment of lumbar degenerative disease has achieved satisfactory results. Unilateral pedicle screw fixation can reduce operation time, intraoperative blood loss and length of stay. Visual Analogue Scale score and Oswestry dysfunction index improved significantly in a short period after treatment.
