AlM: To understand the prognostic factors of myopic rhegmatogenous retinal detachment ( RRD) surgery, and provide guidance for clinical treatment.
METHODS: This retrospective study included 288 myopic RRD eyes ( excluding trauma, aphakia, congenital diseases, tractional and exudative retinal detachment ) from April 2007 to April 2014 in our department. The surgical anatomic reduction situation was statistically recorded, the effects of hole's size, retinal detachment duration on sight restoration and surgery success rate were analyzed
RESULTS:The statistical results showed that 245 eyes (85. 1%) healed after their first operation, about 95. 1%cases finally healed after their second or third operation. The degree of myopia and aging factor influenced the RRD operation:the higher degree and the older age were, the lower success rates were (P<0. 05). Through surgery, postoperative visual acuity was significantly better than the preoperative ones ( P<0. 01 ). A higher degree of myopia RRD led to poor visual acuity ( P < 0. 01 ). Postoperative visual acuity of 152 eyes ( 52. 9%) were improved, of which 106 eyes' visual acuity was 0. 05 or more.
CONCLUSlON:Surgery is an effective means of treating myopic RRD. The older patients have lower success rates. A higher degree of myopia led lower reset rate after retinal detachment surgery and poor postoperative visual acuity. When treat myopic RRD, we should pay attention to the recovery of visual function.

Objective To observe the effect of healthy education on BMD and the risk of bone fracture in pa- tients with primary osteoporosis.Methods 628 patients with primary osteoporosis were randomly divided into two groups under the same conditions,and healthy education were conducted in treated group but were not conducted in control group.Two years later,BMD and the rates of bone fractures were collected and analysed.Results Compared with control groups,the bone loss was significantly lower at the feroral neck,Ward's triangle and the great trochanter,and the risk of bone fractures was remarkably reduced in treated group(P

Objective To observe the expression of synaptotagmin I(syt I)protein in the prefrontal cortex of adult-onset hypothyroidism rats and the effects of replicated therapy in different doses of thyroid hormone on the syt I protein.Methods All 44 aduh male Sprague-Dawley rats were divided into 4 groups randomly according to their body mass:hypothyroidism group,routine dosage thyroxine treatment group,high dosage thyroxine treatment group and control group.The adult male Sprague-Dawley rats were replicated to the adult-onset hypothyroidism and treatment models with propyhhiouracil(PTU).The levels of serum T3,T4 were assayed by the radioimmunoassay method and the level of the syt I protein in the molecular layer,external granular layer,external pyramidal layer,internal granular layer and internal pyramidal layer in prefrontal cortex was analyzed by immunohistochemistry.Results In the hypothyroidism group,the levels of serum T3 and T4[(0.34±0.04),(43.01±2.95)nmol/L]were significantly lower than those in the control group[(0.65±0.15), (55.20±3.56)nmol/L, F value: 6.026,5.940,4.503,P<0.05 or <0.01 ], the levels of the syt I protein in the molecular layer(0.018±0.010), external granular layer (0.020±0.007), external pyramidal layer(0.013±0.008), internal granular layer(0.011±0.005), internal pyramidal layer(0.024±0.013) of prefrontal lobe were significantly lower compared to the control group[(0.028±0.010,0.031 ± 0.010,0.028 ± 0.010,0.022 ± 0.008,0.038 ± 0.013), F value: 5.697,8.965,14.668,13.597,6.807,P<0.05 or <0.01 ]. In the routine dosage of the thyroxine treatment group, the levels of serum T3,T4 [(0.63 ±0.05), (55.04 ± 3.77)nmol/L] were not significantly different compared to the control group(F value: 3.162,0.367,all P>0.05), and the level of the syt I protein in the molecular layer, external granular layer, external pyramidal layer, internal granular layer and internal pyramidal layer in prefrontal cortex showed a significant improvement of the syt I protein(0.027 ± 0.013,0.025 ± 0.009,0.022 ± 0.008,0.020 ± 0.010,0.033 ± 0.010), which were similar to that of the control group(F value: 0.094,2.208,2.467,0.350,0.693, all P>0.05). In the high dosage thyroxine thyroid hormone treatment group, the levels of serum T3 and T4[ (1.11 ± 0.10), (96.68 ± 6.42)nmoL/L] were higher than the control group(F value: 6.291,12.031, all P<0.01), the expression of the syt I protein(0.028 ± 0.008,0.031 ±0.011,0.026 ± 0.012,0.023 ± 0.011,0.038 ± 0.010) were not significantly different compare to the control group (F value: 0.001,0.019,0.111,0.061,0.001, all P>0.05). Conclusions The expression of the syt I protein in the prefrontal cortex of adult-onset hypothyroidism can be decreased, which can be reversed by routine dosage of thyroxine treatment.

OBJECTIVETo explore methods of treating middle and distal tibia nonunion with the treatment of advanced bone graft combined with locking compression plate.

METHODSFrom January 2011 to December 2012, 12 patients with middle and distal tibia nonunion were treated with advanced bone graft combined with locking compression plate. Among patients, there were 8 males and 4 females aged from 20 to 69 with an average of 47 years old. The time from first injuries to bone nonunion was from 9 months to 5 years, avergaed 19 months. Four cases were treated with external fixation, 6 cases were treated with plate fixation, 2 cases of 12 patients occurred broken of plate and nail. Eleven patients were non-infective bone nonunion and 1 patient was infective bone nonunion. Preoperative X-ray and CT showed all patients had sequestration and formation of ossified bone with different degrees. Operative time, blood loss, wound healing were observed, fracture healing time was evaluated by postoperative X-ray. Johner-Wruhs scoring standards was used to evaluate ankle joint function after operation at 10 months.

RESULTSOperative time ranged from 90 to 185 min with an average of (125.00±20.15) min; blood loss ranged from 225 to 750 ml with an average of (415.00±120.00) ml. All patients were followed up from 10 months to 2.5 years with an average of 1.5 years. Postoperative X-ray showed bone union was formed around fracture after operation at 4 months in all patients, 3 cases obtained bone healing within 6 months after operation, 9 cases obtained from 8 to 12 months. No infection, injury of nerve and vessles, and broken of plate and nail were ocurred. According to Johner-Wruhs scoring at 10 months after operation, 10 cases obtained excellent results, 1 good and 1 moderate.

CONCLUSIONAdvanced bone graft combined with locking compression plate, which can build fracture multi-point supporting based on full compression of bone nonunion to get effective fixation, is an effective method in treating middle and distal tibia nonunion.

Low birth weight (LBW) and preterm birth (PB) are associated with newborn mortality and diseases in adulthood.We explored factors related to LBW and PB by conducting a population-based case-control study from January 2011 to December 2013 in Wuhan,China.A total of 337 LBW newborn babies,472 PB babies,and 708 babies with normal birth weights and born from term pregnancies were included in this study.Information of newborns and their parents was collected by trained investigators using questionnaires and referring to medical records.Univariate and logistic regression analyses with the stepwise selection method were used to determine the associations of related factors with LBW and PB.Results showed that maternal hypertension (OR=6.78,95％ CI:2.27-20.29,P=0.001),maternal high-risk pregnancy (OR=1.53,95％ CI:1.06-2.21,P=0.022),and maternal fruit intake ≥300 g per day during the first trimester (OR=1.70,95％ CI:1.17-2.45,P=0.005) were associated with LBW.BMI ≥24 kg/m2 of mother prior to delivery (OR=0.48,95％ CI:0.32-0.74,P=0.001) and gestation ≥37 weeks (OR=0.01,95％ CI:0.00-0.02,P＜0.034) were protective factors for LBW.Maternal hypertension (OR=3.36,95％ CI:1.26-8.98,P=0.016),maternal high-risk pregnancy (OR=4.38,95％ CI:3.26-5.88,P＜0.001),maternal meal intake of only twice per day (OR=1.88,95％ CI:1.10-3.20,P=0.021),and mother liking food with lots of aginomoto and salt (OR=1.60,95％ CI:1.02-2.51,P=0.040) were risk factors for PB.BMI ≥24 kg/m2 of mother prior to delivery (OR=0.66,95％ CI:0.47-0.93,P=0.018),distance of house from road ≥36 meters (OR=0.72,95％ CI:0.53-0.97,P=0.028),and living in rural area (OR=0.60,95％ CI:0.37-0.99,P=0.047) were protective factors for PB.Our study demonstrated some risk factors and protective factors for LBW and PB,and provided valuable information for the prevention of the conditions among newborns.

To investigate the effect of mycobacterium phlei F.U.36 suspended liquor (Utilin"s", U) on the culture and proliferation of dendritic cells (DCs) derived from human umbilical cord blood in vitro, the mononuclear cells (MNCs) were isolated from human umbilical cord blood and cultured with RPMI 1640 in the control group. Test groups consisted of Utilin"s" group (only Utilin"s"), GTI group (GM-CSF, TNF-alpha, IL-4) and GTIU group (GM-CSF, TNF-alpha, IL-4 and Utilin"s"). MNCs in all test groups were cultured with RPMI-1640. The growth of DCs was observed by the light microscopy, the phenotypes of DCs were determined by flow cytometry on the 10th day of culture, and some harvest cells were stained with Wright-Giemsa, then observed and photographed under the oil immersion objective. The results showed that the test groups all displayed some number of typical DCs; both CD1a positive cell rate and HLA-DR positive cell rate of the Utilin"s" group were higher than those of the control; HLA-DR positive cell rate of GTIU group increased most significantly and much higher than that of the GTI group. It is concluded that mycobacterium phlei F.U.36 not only promotes the proliferation of DCs derived from human umbilical cord blood in vitro, but also co-operates with rhGM-CSF, rhTNF-alpha and rhIL-4 in promoting the maturity of DCs.
