Objective To investigate the effect of micro-ecological agent on the intestinal flora of patients with posterior lumbar spine surgery.Methods Seventy-two patients with lumbar spine surgery were selected as our subjects.Of them,42 patients with occurred the intestinal flora dysfunction were served as experimental group (group A),other 30 patients were as control group (group B).The levels of plasma endotoxin,plasma tumor necrosis factor-α (TNF-α),Interleukin 6 (IL-6) were detected before and after operation.The patients in group A were treated with micro-ecological agent Jinshuangqi.Collected stool samples at preoperative,postoperative first natural defecation (after 1-4 d),and compared intestinal flora difference and Bifidobacterium (B)/Enterobacteriaceae (E) value of two groups patients.Results The levels of plasma endotoxin in group A were (1.82 ±0.12),(2.29 ±0.15),(1.91 ±0.08) ng/L at before surgery,the 2nd and 7th day after surgery,and that in group B were(1.91 ±0.21),(2.35 ±0.16),(2.26 ±0.24) ng/L The TNF-α level in group A were (275 ±51),(309 ±45),(276 ±34) ng/L and that in group B were (269 ±48),(318±67),(297 ±53) ng/L at before surgery,the 2nd and 7th day after surgery.The IL-6 levels in group A were (138 ± 22),(159 ± 15),(137 ± 17) ng/L and that in group B were (159 ± 16),(187 ± 19),(174 ± 21) ng/Lat before surgery,the 2nd and 7th day after surgery.The repeated measured repeated measures analysis of variance showed that among three indexes of plasma endotoxin,TNF-α,IL-6 levels,differences of between group and interaction were statistically significant (P ＜ 0.05),but there was no significant difference within groups (P＞ 0.05).The levels of plasma endotoxin,TNF-α,IL-6 decreased after surgery ware gradually decreasing with hospitalization prolonged.There was significant difference between before surgery and at the 2nd,7th day after surgery(P ＜ 0.05),and there was significant difference between the 2nd and the 7th day after surgery(P＜ 0.05).At the 2nd day after surgery,there was significant difference between group A and group B in terms of the level of plasma endotoxin,TNF-α,IL-6.At the 7th day,the levels of plasma endotoxin,TNF-α,IL-6 were slowly decreased in group A,and there were significant difference compared to group B (P ＜ 0.05).The numbers of intestinal Bifidobacterium,Bacteroides,and B/E values of group A were decreased after surgery compared to group B((9.17 ±0.54) lg cfu/g vs.(10.01 ± 0.75) lg cfu/g,(9.23 ± 0.47) lg cfu/g vs.(10.09 ± 0.81)lg cfu/g,(1.01 ± 0.16) vs.(1.20 ± 0.11)),and the difference was significant (P =0.031,0.042,0.029respectively).The levels of Enterobacter and Enterococcus in group A were (9.11 ± 1.02) lg cfu/g,(7.80± 1.02) lg cfu/g,higher than that of group B ((8.81 ± 0.89) lg cfu/g,(7.29 ± 0.98) lg cfu/g(P =0.037,0.043)).There was no significant difference between two groups in terms of small clostridium and lactobacillus (P ＞ 0.05).After treated with micro-ecological agent Jinshuangqi,the levels of intestinal Bifidobacterium,Bacteroides,and B/E value at was increased compared to before treated in group A (Bifidobacterium:(13.01±0.87) lg cfu/g vs.(9.17 ±0.54) lg cfu/g; Bacteroides:(14.12 ±0.75) lg cfu/g vs.(9.23 ±0.47)lg cfu/g; B/E value:(1.28 ± 0.45) vs.(1.01 ± 0.16) ;P =0.045,0.034,0.038 respectively).No significant difference was seen in terms of the levels of Enterobacter,Enterococcus,small clostridium and lactobacillus between two groups(8.71 ±0.91) lg cfu/g vs.(9.11 ± 1.02) lg cfu/g,(7.01 ±0.54) lg cfu/g vs.(7.80± 1.02) lg cfu/g,(5.23 ± 1.04) lg cfu/g vs.(5.15 ± 0.89) lg cfu/g,(6.71 ± 1.04) lg cfu/g vs.(6.53± 0.86) lg cfu/g respectively; P ＞ 0.05).Conclusion Posterior lumbar operation patients with intestinal dysbacteriosis often associated with endotoxemia and inflammatory reaction,the levels of bifidobacteria,Bacteroides intestinal Enterobacteriaceae decrease while Enterococcus,opportunistic pathogens increase,and intestinal microbial colonization resistance decrease.Micro-ecological agent Jinshuangqi treatment can ease the body's endotoxemia and inflammatory response,improved lumbar surgery intestinal flora after surgery,and beneficial to rebuild the intestinal microflora balance.

Objective To evaluate the efficiency of multimodal analgesia for the patients who had the posterior lumbar spine surgery.Methods Sixty-four cases of patients who were scheduled to the posterior lumbar spine surgery were randomly divided into two groups, multimodal analgesia group (n =32) and control group(n=32).Multimodal analgesia group patients were given oxycodone acetaminophen 1 day before and the next day after operation, during the operation the patients received injiection of multimodal drugs (consisting of ropivacaine 150 mg, flurbiprofen 50 mg, phenylephrine 0.4 ml, normal saline 50 ml) around the incisions by infiltrated injection before the skin incision closed, then had controlled intravenous analgesia.In the control group, the incisions were sutured without the local infiltration analgesia.Then only had patient controlled intravenous analgesia after operati on.Visual analogue scale(VAS) ,Japanese Orthopedic Association(JOA) and Prolo lumbar function score was recorded respectively perioperatively.Results (1) VAS: the patients of multimodal analgesia group had significantly lower rest pain scores and activity pain scores at 6, 12,24 hours, first moving than the control group((3.1±1.6) ,(2.8±1.1),(2.4±0.9) ,(2.3±1.1) vs.(3.5±1.8) ,(3.4± 1.3), (3.4±0.8), (3.0± 1.5), P＜0.05).There was no significant difference at the discharge between the two groups (P＞0.05).(2)JOA:JOA scores of the patients of multimodal analgesia group were obviously higher than that of the control group at 1,3,7 days after operation (P＜0.05).There was no significant difference at the discharge between the two groups (P＞0.05).(3) Prolo lumbar function score : Prolo scores of the patients of the multimodal analgesia group were obviously higher than that of control group at 1,3,7 days after operation (P ＜0.05).There was no significant difference at the discharge between the two groups(P＞0.05).Conclusion Multimodal Analgesia is shown to safely provide excellent pain control and functional recovery.It can reduce visual analogue pain score and improve lumbar function after surgery.

Primary vitreoretinal lymphoma (PVRL) is a rare and aggressive high-grade non-Hodgkin lymphoma. PVRL always with non-specific symptoms and has therefore been called as masquerade syndrome. Thus, the early and correct diagnosis of PVRL is a difficulty. For PVRL, the imaging findings can be specific but variety, histological diagnosis is still the gold standard. Its diagnosis needs to be combined with clinical manifestations, imaging features, pathological diagnosis and molecular biology. With the advancement of technology, especially in the field of the cytokines detection and the gene expression profiling research, molecular biology diagnosis of PVRL is becoming a research hotspot and an important auxiliary diagnostic method.

Objective To design and evaluate a new type of acromion & clavicle anatomic plate with combinatorial hinge more suitable for acromioclavicular joint dislocation and distal clavicular fracture.Methods The new type of acromion & clavicle anatomic plate with combinatorial hinge we had designed was used in 21 patients (21 shoulders) who were treated for acromioclavicular joint dislocation or distal clavicular fracture from October 2016 to April 2017 at Department Ⅰ of Orthopaedics,The 2nd People's Hospital of Lu'an.They were 15 men and 6 women,aged from 24 to 63 years(average,41.5 ±4.2 years).Of the 14 cases of acromioclavicular joint dislocation,7 were type Ⅲ,5 type Ⅳ and 2 type Ⅴ,according to the Rockwood classification;all the 7 distal clavicular fractures were Neer type Ⅱ.They were all treated by open reduction and internal fixation with our self-designed acromion & clavicle plate with combinatorial hinge.They were followed up at the outpatients department at 3 weeks,3,6,12 and 15 months postoperatively for evaluation of their shoulder functions by Constant-Murley score,changes in coracoclavicular clearance before and after operation and loss of coracoclavicular clearance after removal of internal fixation by X-ray.Results All the 21 patients were effectively followed up for 15 to 20 months (average,18 months).As for their Constant-Murley scores,preoperation (49.7±4.9) ＜3 weekspostoperation (57.6±5.9) ＜3 monthspostoperation (83.2±5.7) ＜6 months postoperation (90.4 ±4.0) ＜ 12 months postoperation (94.3 ±4.2) ＜ 15 months postoperation (98.1 ±4.2),with significant differences between different time points (P ＜ 0.05).The postoperative coracoclavicular clearances at different time points were all significantly decreased than the preoperative value (P ＜ 0.05).With the aid of our new type of acromion & clavicle anatomic plate,the shoulder functions of the patients were gradually improved,the postoperative acromioclavicular joint and reduction of the distal clavicular fracture were stable,and no re-dislocation occurred after removal of internal fixation.Conclusion Our new handy type of acromion & clavicle anatomic plate with combinatorial hinge can provide more effective internal fixation for acromioclavicular joint dislocation and clavicular distal fracture,facilitating functional recovery of the shoulder.
