Objective To evaluate the prophylatic effect of recombinant human erythropoietin (rhEPO) on bronchopulmonary dysplasia (BPD) of preterm infants. Methods One hundred and fifty-five infants who were born at 26-29+6 weeks of gestation in Department of Neonatology, Guangdong Women and Children Hospital from January 1, 2009 to December 31, 2010 were randomly assigned to rhEPO-treated group (n=78) and control group (n=77) on admission. Randomization was stratified according to gestational age (26 or 27 weeks and 28 or 29 weeks). rhEPO-treated group was given the rhEPO at 300 U/kg, but none for the control group. Forty-eight hours after birth, rhEPO was injected subcutaneously every other day, three times a week for 4 weeks. The supportive care was same in the two groups. The outcomes at 36 weeks gestation included:(1) mortality of the infants;(2) incidence and severity of BPD;(3) rates of the complications, such as pneumonia, sepsis, necrotizing enterocolitis (NEC), intraventricular hemorrhage (IVH), patent ductus arteriosus (PDA), and retinopathy of prematurity (ROP) ; and (4) duration of oxygen and ventilation support. Mann-Whitney U, χ2, Fisher's exact or t test were used for statistical analysis. Results The incidence of BPD in rhEPO-treated group was lower than in the control group [18.6%(11/59) vs 36.8%(25/68),χ2=5.107,P=0.030), but there was no difference in the severity of BPD (P>0.05). There was no significant difference in the mortality rate between the two groups [12.8%(10/78)vs 7.8%(6/77), P>0.05]. The duration of the mechanical ventilation and oxygen therapy was shorter in rhEPO-treated group than in the control group [oxygen therapy:166.4(138.9-198.1) h vs 288.9(287.4-312.9)h, U=361.000;mechanical ventilation:80.5(67.7-95.1) h vs 150.4(148.9-151.9) h, U=88.000;both P<0.05]. There were no significant differences between the two groups in the rates of the complications, including pneumonia, sepsis, NEC, IVH, PDA and ROP, in preterm infants during hospitalization (all P>0.05). Conclusion Prophylatic treatment of rhEPO in preterm infants could decrease the incidence of BPD, and reduce the duration of the mechanical ventilation and oxygen therapy, but without increasing any side effects.

Objective To investigate the effect of cyclic tensile stress (CTS) on the metabolism inand apoptosis of rat chondrocytes.Methods Primary rat chondrocytes were cultured on a Bioflex plate for one day and then stretched cyclically for 24 hours at a frequency of 0.5 Hz using a Flexcell-5000T apparatus.The cells were divided into 5 groups according to their stretching ratio:0％ (the control group),2％,6％,10％ and 14％.After the stretching,Col Ⅱ,Aggrecan,MMP-13 and ADAMTS-5 mRNA were measured using qPCRs,and the NO and PGE2 levels were measured using ELISA kits.Moreover,TUNEL staining and Annexin V-FITC/PI were used to analyze the apoptosis of chondrocytes.Results Compared with the control group,the average levels of Col Ⅱ and Aggrecan mRNAdecreasedin 10％ and 14％ groups [(0.738±0.11) and (0.58±0.13),(0.75±0.11) and (0.55±0.09)].In those groups,the MMP-13 [(2.47±0.47) and (2.88±0.36)] and ADAMTS-5 mRNA level [(2.39±0.33) and (2.75±0.49)],the NO [(6.96±0.96) and (8.28±0.82)] and PGE2 level [(6.83±0.66) and (7.15±0.71)] had increased significantly.In the 6％ group the average levels of Col Ⅱ(1.76±0.30) and Aggrecan mRNA (1.93±0.14)of 6％ group were significantly higher than the control group,but the NO level of the former (3.07±0.20) was significantly lower than the control group (3.89 ± 0.33).The apoptosis rate of chondrocytesin 2％ and 6％ groups were (0.065±0.013) and (0.063 ± 0.147),without significant differences to that of the control group (0.045 ± 0.008).However,compared with the control group,apoptosis in the 10％ and 14％ groups [(0.135 ±0.026) and (0.184±0.020)] increased significantly.Conclusion The effect of cyclic tensile stress on chondrocyte metabolism and apoptosis was magnitude-dependent.Ten percent and 14％ CTS can increase the catabolism and apoptosis of chondrocytes.Ten percent and 14％ strain can increase the catabolism and apoptosis of chondrocytes.Cyclic 6％ strain can increase the anabolism of chondrocytes,but 2％ strain has no impact on metabolism or apoptosis.

Objective To evaluate the clinical results of indirect reduction and fixation with the self-manufactured external fixator as a viable alternative in the surgical treatment of intraarticular calcaneal fractures.Methods From May 2006 to May 2009,a total of 30 patients undergone surgical treatment of intraarticular calcaneal fractures were analyzed,including 20 males and 10 females with an average age of 36 years (range,15-53).According to Sanders classification based on the computed tomography scan of intraarticular calcaneal fractures,16 patients were classified as type-Ⅲ,and 14 type-Ⅳ in this series.All fractures were treated first with the external fixator as indirect reduction and fixation device on the whole,which can enlarge the interspace of the subtalar joint significantly.Then,posterior articular facet of calcaneus was exposed and reduced through a small lateral incision.The calcaneal's length,breadth,thalamus height,maximum vertical displacement of the post-articular surface,and B(o)hler angle were measured preoperatively,3 days and 6 months after operation in X-ray film.Reduction results were evaluated by CT scan according to the standard of Buckley.Results The average follow-up time of all patients was 29 months (range,4-45).Lateral and axial roentgenograms showed satisfactory restoration of the calcaneal's anatomical structure.There were significant differences between preoperative values and those 3 days or 6 months postoperatively.There were no significant differences between values 3 days postoperatively and those 6 months postoperatively.The reduction results of posterior articular facet were evaluated by CT scan.Twenty-seven patients obtained anatomical reduction,3 patients obtained uneven articular facet within 2 mm.Conclusion This selfmanufactured external fixator is a vialbe alternative in the treatment of intraarticular calcaneal fractures,which has advantages of minimal invasion,practicality and less complications.

Objective To investigate the impact flat deformity of the cerebral cortex induced by congenital hydrocephalus on motor functioning and cognition.Methods Tomography was used to confirm the presence of flat cortex deformity in three congenital hydrocephalus patients ranging in age from 20 to 33.Their motor control,balance,cognition and ability in the activities of daily living (ADL) were evaluated using the Fugl-Meyer assessment (FMA),the Berg balance scale (BBS),the mini-mental state examination (MMSE) and the modified Barthel index (MBI).Speech dysfunction was judged on the basis of clinical communication.The patients were scanned using a 64-slice spiral CT and size-of-ventricle indices were calculated.Results All 3 patients underwent ventrideperitoneal shunt.Their FMA scores were 75.5,83 and 100,with BBS scores of 4,24 and 56,MMSE scores of 14,23 and 26,and the MBIs of 40,90 and 100.CT images showed obvious ventricle enlargement and a thinner cortex layer in all three,with the thinnest part 0.18 cm,0.22 cm and 0.57 cm.Their ventricle indexes were 303％,288％ and 192％,respectively.Conclusion Although there is no systematic rehabilitation therapy for such patients,their motor,cognition and speech functioning were good,indicating the great potential for plasticity of the human brain.

Objective To investigate the risk factors for postoperative deep wound infection after open reduction and internal fixation for closed calcaneal fractures.Methods From January 2014 to January 2017,190 patients with closed calcaneal fracture were treated at Department of Traumatic Orthopaedics,Taihe Hospital.They were 118 males and 72 females with an average of 39.8 years (range,from 18 to 73 years).They were divided into a deep infection group and a non deep infection group according to the presence or absence of deep wound infection in the follow-up period.The 2 groups were compared in the general clinical data.In statistical analysis,the related risk factors were first screened by single factor analysis and followed by multivariate logistic regression analysis to identify the independent risk factors associated with the postoperative deep wound infection in patients with closed calcaneal fracture.Results The 190 patients were followed up for an average of 21.3 months(range,from 13 to 31 months).Postoperative deep wound infection occurred in 11 patients,giving an overall incidence of 5.7％ (11 / 190).The single factor analysis showed that the deep infection group incurred significantly longer time for tourniquet and used significantly more conventional extensile lateral approach than the non deep infection group (P ＜ 0.05).There were no significant differences between the 2 groups in general data,injury cause,fracture type,drainage,or incision closure technique (P ＞ 0.05).The multivariate logistic regression analysis revealed that tourniquet time ＞ 80 min (OR=5.949,95％ CI:1.216～ 29.108,P=0.028) and conventional extensile lateral approach (OR =5.414,95％ CI:1.507 ～ 19.452,P =0.01) were independent risk factors fo r the postoperative deep wound infection in patients with closed calcaneal fracture after open reduction and internal fixation.Conclusions Tourniquet time and conventional extensile lateral approach may be the independent risk factors for postoperative deep wound infection in patients with closed calcaneal fracture after open reduction and internal fixation.Therefore,it is important to adopt the sinus tarsi approach and control tourniquet time within 80 minutes for prevention of deep wound infection as long as the surgical quality is ensured.

Porcine deltacoronavirus (PDCoV) is a newly emerging enteropathogenic swine coronavirus causing acute diarrhea and vomiting in pigs. The apoptosis of ST cells induced by PDCoV infection was studied in this research. In ST cells, caspase activity assay showed that the activity of caspase 3, caspase 8 and caspase 9 increased significantly with the infection of PDCoV, but not observed in UV irradiated PDCoV-infected cells, indicating that PDCoV infection activated both endogenous and exogenous apoptotic pathways in ST cells, and the induction of apoptosis depended on viral replication. To further investigate the endogenous apoptosis induced by PDCoV, cytochrome C and apoptosis-inducing factors in cytoplasm and mitochondria were detected. Compared with normal cells, the amount of cytochrome C released from mitochondria to cytoplasm increased significantly in PDCoV-infected cells, and the release increased with the prolongation of infection, while the apoptosis-inducing factor was always localized to mitochondria, suggesting that PDCoV induced apoptosis was initiated through caspase-dependent mitochondrial apoptosis pathway by promoting cytochrome C in the mitochondrial membrane gap into the cytosol. In conclusion, this study reveals the mechanism of PDCoV inducing apoptosis.
