AIM: To evaluate the preservation of anterior capsule during vitrectomy and lensectomy.ment (RD) and grade C proliferative vitreoretinopathy (PVR)underwent pars plana vitrectomy (PPV) and pars plana lensectomy (PPL) with preservation and polishing of the anterior capsule. Of the 15 eyes, 4 eyes had giant tear, 3 had recurrent rhegmatogenous retinal detachment (RRD), 2 had diabetic retinopathy. Totally 6 eyes had gas and 9 had silicone oil tamponade. The surgeries were evaluated according to the visual acuity (VA) and the postoperative complications during the follow-up of at least 3 months.in all eyes, improved by 3± 3 lines overall. Eight eyes were implanted posterior chamber intraocular lens (PCIOL) successfully at 2-3 months after operation, including 6 having gas and 2 having silicone oil tamponade. No eyes had central anterior capsule opacity, corneal decompensation, puplillary block, retina redetachment or other complications.an intact anterior capsule in eyes with RD and PVR. Preserving the anterior capsule can help preventing intraoperative and postoperative complications of gas or silicone oil, simplify future PCIOL placement, and maintaining a normal iris appearance.

BACKGROUND: Current commonly used bone graft materials include cancellous bone or bone blocks from ilium, tibia, fibula and others. There is no report of bone graft and fusion in cervical spine from manubrium sterni. OBJECTIVE: To measure lateral X-ray of cervical vertebrae with no degeneration and manubrium sterni samples to explore feasibility of autologous cancellous bone graft of manubrium sterni with pyramesh in anterior cervical spinal fusion surgery, so as to develop a new source of autogenous bone graft.METHODS: A total of 40 manubrium sterni specimens were selected and the length, maximum width and minimum width, thickness, anterior and posterior cortex thickness of manubrium sterni were measured. Manubrium sterni area was calculated: the length, maximum width and minimum width were 4 mm reduced from those of manubrium sterni, its thickness was 2 mm reduced from that of manubrium sterni. The formula of measuring the manubrium sterni volume is (maximum width of manubrium sterni + the minimum width of manubrium sterni)×length of manubrium sterni × thickness of manubrium sterni×1/2. Intervertebral height and vertebral height from C2 to C7 were measured from lateral cervical radiograph of 106 patients with cervical radiolopathy, and the length of pyramesh needed in anterior cervical spinal surgery for one, two, three discs resection, one vertebra plus two discs resection and two vertebrae plus three discs resection was calculated. RESULTS AND CONCLUSION: The manubrium sterni volume was (17 735.51±5 234.92) mm3 and the volume of bone-grafting area was (8 982.83±2 427.76) mm3. The length of pyramesh and volume of bone used in operation were minimal for one disc resection, and maximal for two vertebrae plus three discs resection. The volume of bone graft in the pyramesh was significantly less than the donor area in any anterior cervical spinal fusion operation. Results show that autologous cancellous graft of manubrium sterni combined with pyramesh supporting can be used in anterior cervical spinal fusion surgery. Compared with autologous iliac graft, this method is simpler and does not influence early functional exercise or walking bearing weight.

In view of the predominance problems in present experimental teaching of medical microbiology, we reformed the experimental contents and experimental teaching methods,to establish an entire experimental curriculum teaching system to be suitable for seven-year system and long educational system students,which manifests the creative teaching idea.

In this study, we use pot experiment to evaluate the effect of plant growth regulator on plant morphology and biomass allocation of Salvia miltiorrhiza. Different concentrations of uniconazole were supplied to S. miltioohiza by means of foliar spray. Height, breadth and stem diameter were measured dynamically, the biomass of leaf, stem, flower and fruit, root biomass and biomass ratio were also examined at the harvest time. Owing to the treatment, plant morphology showed significant changes, the height had been greatly reduced and the breadth decreased largely. Meanwhile, the biomass allocation changed too. The biomass ratio of leaf and stem had been notably reduced while the biomass ratio of root had been increased remarkably. It appears that foliar application of uniconazole during vigorous growth period in S. miltioohiza has dramatic effect on dwarfing plant and improving resistant to lodging. This measure could also be applied to condensed cultivation of S. miltioohiza to increase production.

The types of 3D printing rapid prototyping manufacturing technology were introduced,and the advantages and disadvantages of 3D printing technology and traditional printing technology were compared.Examples were taken to describe the problems and countermeasures of 3D printing technology in clinical medicine,and it's pointed out 3D printing technology may have of great significance for enhancing medical service,decreasing medical cost and promoting individualized medical service.

The aim of the present study was to examine the relationship between the protein expression of vascular endothelial growth factor (VEGF) and lymph node metastasis (LNM) in papillary thyroid cancer (PTC).VEGF-related articles that had been published until August 2016 were searched from the PubMed,EMBASE,and MEDLINE to identify the risk factors of LNM in PTC.RevMan 5.3 software was used for the meta-analysis.Finally,9 articles met the inclusion criteria and were included in our meta-analysis.LNM was found to be present in 176 of 318 patients (57.8％) with high VEGF expression and in 71 of 159 patients (47.0％) with low VEGF expression.The overall OR was 2.81 (95％ confidence interval,1.49-5.29).LNM occurred more frequently in patients with high VEGF expression than in those with low VEGF expression (P=0.001).Heterogeneity was markedly decreased in the subgroup analyses of LNM in terms of the patients' country of origin and the detection methods.Our meta-analysis concluded that the VEGF protein expression is associated with LNM in PTC.

OBJECTIVETo investigate the efficacy of oral sweet solutions in relieving pain caused by vaccination in infants aged 1 to 12 months.

METHODSRelated databases were searched to find related randomized control trails (RCTs). The quality of these RCTs was evaluated. The Meta analysis was performed using RevMan 5.3.

RESULTSA total of 20 RCTs involving 2 376 infants were included, and quality assessment showed that 6 RCTs had grade A quality and 14 had grade B quality. The Meta analysis showed that compared with sterile water, 25%-75% oral sweet solution significantly reduced crying time (WMD=-21.16, 95%CI -39.66 to -2.77, P<0.05) and the proportion of crying time (the duration of crying /3-minute periods after the injection) (WMD=-13.83, 95%CI -20.88 to -6.78, P<0.01), while the crying time showed no significant difference between the group treated with oral administration of 12% sucrose solution and non-intervention group.

Objective To investigate the role of overexpression of Smad7,the inhibitory factor of TGF-?/Smads signaling,in epithelial-mesenchymal transition (EMT) of peritoneal mesothelial cells.Methods Peritoneal fibrosis rat model was built by daily intraperitoneal injection with 4.25% Dineal (100 ml/kg) and lipopolysaccharide(LPS) (0.6 mg/kg) at day 8,10,12,22,24,26. Smad7 or control empty vectors was transferred at day 0,14 and was induced by doxycline in the daily drinking water (200 mg/L).Rats were sacrificed on day 28 and the expression of TGF-beta/ Smads,?-SMA and E-cadherin was examined.Results Compared with normal rats,empty vector rats showed higher expression of phosphorylated Smad2/3.?-SMA expression was elevated but E-cadherin was reduced.Under electron microscope,the mesothelial cells removed to submesothelial zone and showed large bundles of actin microfilaments and dense bodies within the cytoplasm. Basement membrane was broken.After induction of Smad7 in peritoneal fibrosis rats,the morphology of mesothelial ceils normalized partly,phosphorylated Smad2/3 was reduced.Moreover,expression of E-cadherin was increased,expression of?-SMA was dramatically reduced.Conclusion Inhibition of TGF-?/Smad signaling by Smad7 overexpression may inhibit the epithelial-mesenchymal transition of mesothelial cell,which may provide a new therapeutic method for peritoneal fibrosis by overexpression of Smad7.
