Objectives To investigate the treatment and curative effect on paranasal sinuses and bronchitis in children. Methods Treatment of 62 cases of paranasal sinuses and bronchiolitis was retrospectively analyzed. Antibiotics was used in conventional treatment group (n=23). On top of conventional treatment, conventional plus topical treatment group (n=39) was additionally treated with nasal inhaled corticosteroids, sinus puncture, adenoid or tonsil surgery, etc. Results In conventional treatment group and conventional plus topical treatment group, the total effective rate of treatment for more than 8 weeks was 86.96%and 100.00%respectively, the effective rate for those treated for 4-8 weeks was 39.13%and 61.54%respectively. There was signiifcant difference in the effective rate of treatment for more than 8 weeks and for 4-8 weeks (both P<0.05) between two groups. Signiifcant difference also existed between the effective rate of treatment for more than 8 weeks and for 4-8 weeks (P<0.05) in each group. Conclusions Childhood sino-bronchitis should be treated not only with conventional treatment, but also with cor-rect topical treatment for local pathological changes in nasal sinus and nasopharynx. Longer treatment is needed for children with recurrent chronic sino-bronchitis.

●METHODS: Retrospective study. A total of 126 cases (150 eyes) were selected from Jan. 2014 to Dec. 2015 in Changzhou First People′s Hospital of cataract extraction combined with foldable intraocular lens implantation for cataract patients as the research samples. According to the different operation for three groups, the first group of 42 patients ( 50 eyes ) underwent above 3 mm clear corneal incision;52 cases in group 2 (60 eyes) underwent temporal side 3 mm clear corneal incision. The third group, 32 cases (40 eyes) underwent 3 corner above the scleral tunnel incision. All the cases were measured at different time point in patients with naked eyes far visual acuity, best corrected visual acuity, spherical degree, the degree of astigmatism and astigmatic axial, comparative analysis of after cataract surgery in patients with refractive change regularity and stability of refraction.
●RESULTS: The uncorrected distance visual comparison within the group, and each time point after preoperative differences were significant ( P< 0. 01 ), and the early postoperative period after 1, 3mo significantly different (P<0. 05). Three groups of patients after surgery compared with preoperative uncorrected distance visual acuity improved significantly, and were stable after 1mo. Compare the best corrected distance vision within the group, and each time point after preoperative differences were significant (P<0. 01), postoperative 1wk and after 1, 3d significantly different (P<0. 05), after 1wk and after 1, 3mo was not significantly different ( P > 0. 05 ), three groups of patients were compared with the preoperative best corrected distance visual acuity were increased significantly, and were in stable after 1wk; relatively spherical degree within the array, after 1d and 3d was not significantly different (P>0. 05), hyperopia drift, after 1wk and 1, 3d was significantly different (P<0. 05), after 1wk and 1, 3mo was not significantly different ( P>0. 05 ). Three groups of patients′spherical degrees after 1wk were stabilized. Comparative degree of astigmatism within the array, postoperative compared with preoperative corneal astigmatism were increased 1d after surgery. Corneal astigmatism in each group reached the maximum, and then decreases 1wk and 1d after surgery, compared with postoperative 3d was significantly different ( P<0. 05 ). After 1wk and 1, 3mo was not significantly different ( P>0. 05 ) . Three groups of patients were compared with preoperative astigmatism were significantly increased, and in operation after 1wk were stabilized;astigmatic axis were three groups in the preoperative astigmatism against the rule, the first and third group after 1d, three Tianshun rule astigmatism proportional were increased, and then decreased. Group 2 the- rule astigmatism proportion, after 1wk, 1 and 3mo, the first and third group gradually reduced the proportion of cis regulatory astigmatism, and compared with preoperative increased, increasing the-rule astigmatism group 2 ratio, and increased compared with preoperative.
●CONCLUSION: Above 3 mm the transparent corneal incision, temporal clear corneal incision and above the scleral tunnel incision different surgical postoperative visual acuity are good. lt can be used as a routine surgical procedure in treatment of cataract;phacoemulsification in cataract patients with former majority against the rule astigmatism. After cataract surgery, early refractive state is a state of mild hyperopia and stabilized about 1wk, combined with clinical guide glasses.

A total of 183 patients of ectopic pregnancy due to tubal factors were divided into the methotrexate (MTX),conservative surgery and salpingectomy groups.The dose of gonadotropin,counts of harvested oocytes and high-quality embryos and pregnancy rate were compared among three groups to analyze the differences of in vitro fertilization and embryo transfer (IVF-ET).And the above parameters showed no significant differences (P ＞0.05 ).The clinical pregnancy rate of the conservative group was higher than the other two groups.And the difference was statistically significant compared with salpingectomy ( P ＜ 0.05 ).It suggested that the treatments of ectopic pregnancy had some effects on the outcome of IVF-ET.The pregnancy rate was slightly higher in the conservative surgery group.

BACKGROUND:Selection of resin core materials may affect the overal strength of the fiber posts.
OBJECTIVE:To compare the overal flexural strength of five kinds of resin core materials combined with glass fiber posts.
METHODS:Fifty viva glass fiber posts were randomly divided into five groups respectively binding to five different resin materials for repair:group A, MEDENTAL dual curing resin cement+glass fiber post;Group B, Tina dual curing resin cement+glass fiber post;group C, Bisco BisCem+glass fiber post;group D, 3M nano composite resin curing light P60+glass fiber post;group E, PULPDENT dual curing resin cement+glass fiber post. The root canals were embedded with self-curing plastic, and fixed in the universal testing machine. The load in tooth length axis was added onto the core at a 135° angle with a loading speed of 1.0 mm/min, until the fracture. Then, the stress at fracture and the fracture mode were measured.
RESULTS AND CONCLUSION:The flexural strength was (83.248±7.857) N in group, (89.230±4.326) N in group B, (95.188±5.147) N in group C, (76.646±6.463) N in group D, and (83.064±3.964) N in group E. Except groups A and E, there were significant differences between every two groups (P<0.05). These findings indicate that Bisco BisCem resin cement binding to the fiber post can obtain a higher flexural strength.

BACKGROUND:Expanded polytetrafluoroethylene is a kind of porous polymer materials which is commonly used as clinical implants, and it has good biocompatibility, and is not easy to deformation or metamorphism. There is no existence of inflammation absorption reaction, and it al ows the cel migration and tissue ingrowth.
OBJECTIVE:To study the biocompatibility of expanded polytetrafluoroethylene scaffold and human adipose-derived stem cel s.
METHODS:The passage 4 human adipose-derived stem cel s were co-cultured with expanded polytetrafluoroethylene scaffold in vitro. The morphology and function of cel s adhered to the scaffold were observed by inverted phase contrast microscope, and cel adhesive rates and proliferation rates were also calculated by MTT assay.
RESULTS AND CONCLUSION:The inoculated cel s were round and bright, distributed on the surface of scaffolds uniformly, with good cel viability. After 3 hours a large number of adherent cel s were observed from the micrograph;after 24 hours there were a smal amount of short-spindle adipose-derived stem cel s. After cultured for 3 days, the short fusiform or polygon cel s could be seen clearly. After cultured for 7 days, the number of cel s increased significantly, few cel s fel off from the scaffold, and cel adhesion rate was up to an average of 95.7%. Meanwhile, the cel s revealed normal splitting proliferation rate. These findings indicate that human adipose-derived stem cel s are able to attach, grow and proliferate wel on the scaffold. Expanded polytetrafluoroethylene reveals excel ent cel ular compatibility and can be used as a vehicle for adipose tissue engineering.

Objective To explore the value of dynamic monitoring of the neutrophils/lymphocyte ratio ( NLR ) in peripheral blood for the prognosis of patients with bloodstream infection ( BSI ). Methods A retrospective study was conducted. 205 patients who were≥18 years old, their length of hospital stay>24 hours, and they were treated in the China-Japanese Friendship Hospital from January 2013 to October 2014 were enrolled. According to the 28-day survival, the patients were divided into survival group ( n=160 ) and death group ( n=45 ). The white blood cell ( WBC ), neutrophils count ( NEU ), neutrophils ratio ( Neut%), lymphocyte count ( LYM ), lymphocyte ratio ( Lym%), and NLR in peripheral blood were recorded at 1, 3, 7 days after admission. Receiver-operating characteristic curve ( ROC ) was plotted for evaluating the value of these factors on the 28-day prognosis, and logistic regression analysis was used to evaluate the risk factors for predicting the outcome. Results ①On the 1st day, WBC, NEU, Neut%, NLR, and procalcitonin ( PCT ) in the death group were significantly higher than those in the survival group [ WBC (×109/L ):15.28±8.23 vs. 11.58±6.55, NEU (×109/L ):13.34±7.53 vs. 10.03±5.31, Neut%:0.886±0.076 vs. 0.845±0.102, NLR:21.20 ( 13.10, 28.80 ) vs. 12.08 ( 6.81, 20.47 ), PCT (μg/L ):3.13 ( 0.85, 10.12 ) vs. 1.34 ( 0.36, 5.81 ), P<0.05 or P<0.01 ], while hemoglobin ( Hb ), platelet count ( PLT ), albumin ( ALB ) content were significantly lower than those of the survival group [ Hb ( g/L ):86.09±19.83 vs. 107.89±22.82, PLT (×109/L ):157.51±117.81 vs. 195.44±97.28, ALB ( g/L ):24.11±6.94 vs. 31.99±6.89, P<0.05 or P<0.01 ]. On the 3rd day and 7th day, WBC, NEU and NLR in the death group were significantly higher than those of the survival group [ WBC (×109/L ):16.61±10.25 vs. 8.91±4.93, 16.05±9.46 vs. 8.79±4.45; NEU (×109/L ): 14.15±9.98 vs. 6.97±4.64, 14.36±9.03 vs. 6.59±4.07; NLR: 24.13 ( 8.49, 38.26 ) vs. 5.52 ( 3.58, 8.87 ), 17.74 ( 10.74, 32.85 ) vs. 4.35 ( 2.78, 7.27 ), all P<0.01 ], and the LYM and Lym%were significantly lower than those in the survival group [ LYM (×109/L ):0.61 ( 0.38, 1.04 ) vs. 1.05 ( 0.78, 1.43 ), 0.69 ( 0.35, 0.92 ) vs. 1.37 ( 0.93, 1.76 );Lym%:0.039 ( 0.024, 0.101 ) vs. 0.135 ( 0.094, 0.186 ), 0.056 ( 0.033, 0.082 ) vs. 0.170 ( 0.108, 0.237 ), all P<0.01 ].②It was shown by ROC curve that the maximum area under the ROC curve ( AUC ) of WBC, NEU, Neut%, LYM, Lym%, and NLR about prognosis of BSI were observed on 7 days ( 0.777, 0.819, 0.905, 0.755, 0.880, 0.887 ). Based on Neut%>0.855 on the 7th day as a predictor of cut-off value of death in 28 days, the sensitivity was 78.8%, specificity 89.1%, respectively. When Lym%<0.088 on the 7th day as a predictor of cut-off value of death on 28 days, the sensitivity was 89.5%, and specificity was 83.9%. When NLR>10.34 on the 7th day as a predictor of cut-off value of death in 28 days, the sensitivity was 81.8%, and specificity was 91.0%.③Survival analysis showed that the 28-day survival rate in the patients with 7-day NLR<10.34 was significantly higher than that in those with 7-day NLR>10.34 ( 95.0%vs. 34.1%,χ2=82.650, P=0.000 ).④It was shown by multi-factor logistic regression analysis that the levels of 1-day Hb and 7-day NLR were the independent prognostic predictors of 28-day mortality [ Hb: odds ratio ( OR ) = 0.946, 95% confidence interval ( 95%CI ) = 0.913-0.981, P = 0.003; 7-day NLR:OR=34.941, 95%CI=8.728-139.884, P=0.000 ]. Conclusions The trend of changes in NEU, LYM and NLR as shown by repeated routine blood examinations contributes to prediction of the outcome of patients with BSI. The levels of 1-day Hb and 7-day NLR are the independent prognostic predictors for 28-day mortality.
