Objective To compare the effect of proximal femoral intramedullary nail fixation and femoral retrograde intramedullary nail combined with hollow lag screw fixation in the treatment of ipsilateral femoral neck and shaft fractures.Methods Data of 42 patients with ipsilateral femoral neck and shaft fractures who were admitted in our hospital from January 2007 to January 2016 were retrospectively analyzed.According to different fixation methods,the patients were divided into two groups:single intramedullary nail group (SIN group) (20 cases,treated with single proximal femoral intramedullary nail,15 males and 5 females with an average age of 39.4);combined internal fixation group (CIF group) (22 cases,treated with femoral distal intramedullary nail combined with femoral neck hollow lag screw,17 males and 5 females with an average age of 42.2 years).In the SIN group,4 cases were type A,9 cases type B,7 cases type C according to AO classification.And 14 cases belonged to Ⅰ or Ⅱ (stable fracture),6 cases of type Ⅲ or Ⅳ (unstable fracture) according to Garden classification.In the CIF group,3 cases were type A,10 cases type B,9 cases type C according to AO classification.And 16 cases belonged to type Ⅰ or type Ⅱ,6 cases type Ⅲ or Ⅳ according to Garden classification.The incision length,operation time,intraoperative blood loss,fracture healing time,postoperative weight time,stability of internal fixation,hip function score,pain in the knee and postoperative complication rate were compared between the two groups.Results There was no significant difference in gender,age and fracture classification between the two groups.The operation time (75.0±10.2 min),intraoperative blood loss (150.6±80.4 ml),hip Harris score excellent rate (80％) of incidence of knee pain in postoperative 3 months (10.0％) of the SIN group were significantly lower than those of the CIF group (105.2±18.4 min,180.0±56.8 ml,86.4％ and 31.8％).The length of incision (8.3±1.4 cm) in the SIN group was significantly longer than that in the CIF group (4.0±0.6 cm).There was no significant difference in fracture healing time (SIN group 20.O±4.0 weeks,CIF group 19.6±4.2 weeks) and postoperative weight time (SIN group 8.2±4.0 weeks,CIF group 8.0±4.2 weeks) between the two groups.The main complications of the two groups were delayed union (3 cases of SIN group and 1 case of CIF group),nonunion of fracture (1 case of SIN group) and,coxa vara (1 case of SIN group).The complication of SIN group (30％) was significantly higher than that of CIF group (4.5％),which occurred mainly in unstable femoral neck fracture cases.Conclusion Both proximal femoral intramedullary nail fixation and femoral retrograde intramedullary nail combined with hollow lag screw can effectively treat femoral ipsilateral femoral neck and shaft fracture.Femoral retrograde intramedullary nail combined with hollow lga screw has more therapeutic advantages for unstable femoral neck fractures (Garden Ⅲ and Ⅳ).

Objective To investigate the risk factors for postpartum cardiac events in pregnant women with heart diseases and to provide prenatal counseling for them.Methods A retrospective analysis was made in cases of pregnant women with heart diseases admitted to the surgical intensive care unit (SICU) of Anzhen Hospital from May 2004 to May 2012.Data were used to identify univariate and multivariate predictors for postpartum cardiac events.Results A total of 190 patients (≥ 20 weeks gestation) were enrolled in the study with 134 (70.5％) of congenital heart disease,30 (15.8％) of rheumatic heart disease,10 (5.3％) of cardiomyopathy,2 (1.1％) of peripartum cardiomyopathy and 14(7.4％) of hypertensive heart disease.Postpartum cardiac events were observed in 42 cases with the incidence of 22.1％.A total of 7 cases resulted in death with the mortality rate of 3.7％.Among them,5 cases were dead of circulatory collapse and pulmonary hypertensive crisis postpartum,while the other 2 cases with secondary pulmonary infection were died of respiratory and circulatory collapse.The baseline parameters of New York Heart Academy(NYHA) ＞ 1,left ventricular ejection fraction (LVEF) ＜ 50％,use of cardiac drugs and pulmonary artery hypertension(PAH) ＞ 80 mm Hg(1 mm Hg =0.133 kPa) were the independent predictors for postpartum cardiac events by univariate and multivariate logistic regression analysis.Conclusions The incidence of postpartum cardiac events is high in pregnant women with heart diseases.Pulmonary artery hypertension and heart failure are the main causes of death.

Objective To study the effects of Schwann cell-derived neurotrophic factor(SDNF) on myoblast stem cells(called satellite cells,SCs) in vitro. Methods After setting up SCs culture system in vitro, SCs which treated with various SDNF concentrations culture medium were dynamically evaluated by cell morphology,MTT growth curve and fusion rate. Results The ability of SCs preceding their participation in muscle repair include proliferation and differentiation, 200 ng/ml SDNF stimulated cell proliferation more than the other medium,but 50 ng/ml,100 ng/ml,200 ng/ml,400 ng/ml SDNF made SCs differentiation significantly for their high myotube fusion rate. Conclusion SDNF can regulate the proliferation and differentiation of rat skeletal satellite cellsin vitro,but in differentiation significantly.SDNF might play a role in slowing down denervated muscle atrophy.

Objective To compare the clinical effect between small incision surgery and traditional resection for thyroid adenoma. Methods 60 patients with thyroid adenoma were divided into two groups according to different surgical methods. 30 patients in the observation group underwent small incision resection, and 30 patients in the control group underwent conventional thyroid tumor resection. The postoperative surgical results, the intraoperative blood loss, operation time, hospital stay and postoperative complications were compared between the two groups. Results The intraoperative blood loss of the observation group was (19.15±8.30) mL, which was significantly than that of the control group. The operation time of the observation group was (78.73±12.61) min, which was significantly than that of the control group.The hospitalization time of the observation group was (3.74±1.05) d, which was significantly shorter than that in the con trol group, and the difference was significant (P<0.05). After operation, the total effective rate of the observation group was significantly higher than that of the control group, and the difference was significant (P<0.05). The postoperative complication rate of the observation group was significantly lower than that of the control group. There was significant difference between the two groups (3.3％ vs 16.7％, P<0.05). Conclusion Small incision surgery is more effective than traditional resection for thyroid adenoma. It has the advantages of small incision, less bleeding, less complications, and quick recovery after surgery.It is worthy of widespread application and application.

Objective To investigate the perinatal outcome , risk factors and long-term outcome of pregnancy complicated with pulmonary arterial hypertension (PAH) and congenital heart diseases (CHD). Methods Clinical data of 110 pregnant women who were diagnosed as PAH-CHD were retrospectively analyzed in the Department of Obstetrics and Gynecology and Surgical Intensive Care Unit at Beijing Anzhen Hospital from 2004 to 2013.The survival and treatment status were followed up .Results 110 subjects consisted of 11 mild PAH, 33 moderate and 66 severe ones .The incidences of deterioration in New York Heart Association ( NYHA ) classes (≥2 ) during pregnancy , respiratory failure , pulmonary hypertension crisis and arrhythmia were 25.5% (28/110),7.3% (8/110),10.0% (11/110),10.0% (11/110) respectively.Among them, the difference of deterioration in NYHA classes (≥2) during pregnancy among the three groups was statistically significant .A total of 8 ( 7.3%) maternal deaths occurred during hospitalization , all of whom were severe PAH cases .Multivariate analysis showed that pulmonary artery systolic pressure was a risk factor of perioperative death (OR=1.042, P=0.005).There were 55 cases (50.0%) of term delivery, and 35 cases (31.8%) of iatrogenic abortion.The proportion of term delivery in the severe PAH group was significantly lower . The proportion of iatrogenic abortion and small for gestational age infant ( SGA ) were higher in severe group .The incidence of neonatal malformations was 8.0%(6/75).The follow-up rate was 61.8%(63/102).Sudden death was reported in a parturient a few days after discharge .The remaining 62 patients survived during follow-up, while 53 patients (85.5%) were functional class ( FC ) Ⅰ -Ⅱ, 9 ( 14.5%) were FC Ⅲ -Ⅳ at follow-up.The cardiac function deterioration during pregnancy was not significantly correlated with long-term deterioration (P =0.767). Conclusions Perinatal mortality and the incidence of maternal and fetal adverse events were high in pregnancy with PAH-CHD.Pulmonary artery systolic pressure is a major risk factor for perioperative mortality in pregnant women .PAH-CHD woman had good overall outcome after puerperium .

Objective:To study the clinical and laboratory characteristics of neonatal isolated sulfite oxidase deficiency (ISOD).Methods:An infant with neonatal ISOD admitted to our hospital was retrospectively analyzed. Using key words "isolated sulfite oxidase deficiency", "SUOX gene", "Infant, newborn", databases including CNKI, Wanfang database, National library and literature center of science and technology, China science paper online, PubMed, Web of Science and EMBASE (up to January 2021) were searched and literature review was conducted. The clinical manifestations, laboratory results, treatment and prognosis were analyzed.Results:Our patient was a full-term male infant with eye movement disorder, refractory seizures, feeding difficulties, increased muscle tone, developmental retardation and microcephaly. Urine sulfite paper-strip test was positive. Uric acid was normal. Whole exon sequencing (WES) revealed SUOX c.475G>T and c.1201A>G compound heterozygous mutations. Cranial MRI showed multiple encephalomalacia and brain atrophy at 5-month of age. The infant died at 8-month. In the literature review, a total of 29 articles and 32 cases of neonatal ISOD were found. 87.5% of the cases developed symptoms within 1-week after birth. All had convulsive seizures. Some of them had feeding difficulties, muscle tone changes, developmental retardation, microcephaly and ectopia lentis. Cranial imaging showed white matter cystic lesions and brain atrophy. Laboratory examination showed elevated urinary sulfite and S-sulfocysteine. Uric acid and xanthine/hypoxanthine were normal. Blood homocysteine was decreased. 23 cases received genetic testing and all of them had SUOX mutations. The treatment was mainly symptomatic relief and supportive treatment. During follow-up, 15 cases died, 13 cases survived and 4 cases were unknown. All the surviving children had drug-resistant convulsions and developmental retardation.Conclusions:Neonatal ISOD may present with refractory convulsions, feeding difficulties and developmental retardation. Cystic white matter changes and brain atrophy may be seen on cranial imaging. Elevated urinary sulfites, decreased blood homocysteine and normal uric acid are important clues for diagnosis. Genetic testing is helpful for early diagnosis.

Objective:To evaluate the functional and anatomical outcomes of autologous single retinal pigment epithelium (RPE) transplantation for severe obsolete submacular hemorrhage (SMH) in late age-related macular degeneration (AMD).Methods:A retrospective clinical study. From January 2012 to December 2015, 11 patients with AMD (11 eyes) with obsolete SMH who were diagnosed and treated by pars plana vitrectomy (PPV) combined with autologous RPE transplantation at the Department of Ophthalmology, Xin Hua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine were included. Among them, there were 9 eyes in 9 males and 2 eyes in 2 females. All the eyes underwent the examinations of best corrected visual acuity (BCVA) and optical coherence tomography; 4 eyes underwent macular fixation function (MAIA) at the same time. The BCVA examination was carried out using the international standard visual acuity chart, which was converted into logarithm of the minimum angle of resolution (logMAR) visual acuity during statistics. All eyes were treated with PPV combined with autologous single-layer RPE transplantation or autologous RPE-choroidal full-thickness transplantation, and were divided into S group and C group, with 5 and 6 eyes respectively. The differences of age ( t=-0.363), gender composition ratio ( χ2=0.549), course and thickness of SMH ( t=0.118, 0.231), average times of anti-vascular endothelial growth factor drug treatments ( t=0.129), times of PPV ( t=-0.452) between the two groups were not statistically significant ( P>0.05). The follow-up period was 6-40 months after the operation, and the BCVA, MAIA, graft status and complications of the eyes after the operation were observed. The comparison of continuous variables between groups was performed by independent-sample t test; the comparison of categorical variables was performed by χ2 test. Results:At the last follow-up, the average logMAR BCVA of the eyes in group S and C were 1.62±0.34 and 1.03±0.20, respectively; group C was better than group S, however, the difference was not statistically significant ( t=1.532, P=0.160). There were 4 eyes (80%, 4/5) and 6 eyes (100%, 6/6) in S group and C group with BCVA better than preoperative, the difference was no statistical significance ( χ2=0.677, P=0.895). There were 2 (40%, 2/5) and 3 (50%, 3/6) eyes with logMAR BCVA better than 1.0 in S group and C group, and the difference was not statistically significant ( χ2=0.572, P=0.423). After the operation, 6 eyes of grafts were in good condition and 5 eyes were in poor condition; the BCVA of grafts in good condition was significantly higher than that of poor condition, the difference was statistically significant ( t=4.894, P=0.001). Among the 4 eyes that underwent MAIA examination, 2 eyes were unstable and diffusely fixed on the graft; the fixation point was located at the normal retina adjacent to the graft area in 2 eyes. Secondary subretinal hemorrhage occurred in 3 eyes after the operation; the intraocular pressure was high in 1 eye after the operation. During the follow-up period, no intraocular infection, secondary retinal detachment, recurrent choroidal neovascularization or low intraocular pressure occurred in all eyes. Conclusions:Both autologous single-layer RPE transplantation and autologous RPE-choroidal full-thickness transplantation can help stabilize or even improve the visual function of eyes with severe SMH secondary to advanced AMD. The visual acuity after surgery is closely related to the state of the graft.

Objective:To investigate the clinical significance of changes of serum Clara cell secretory protein(CC16) and pulmonary surfactant protein A(SP-A) in neonates with acute respiratory distress syndrome(ARDS).Methods:The data of 30 neonates with ARDS who needed mechanical ventilation in neonatal intensive care unit of Xi′an Children′s Hospital from January 2016 to November 2018 were collected as observation group, including 12 cases in mild group, 10 cases in moderate group and 8 cases in severe group.The data of healthy newborns during the same period were taken as control group.The serum levels of CC16 and SP-A were detected by ELISA.The serum levels of CC16 and SP-A among different groups were compared.Results:The levels of serum CC16 and SP-A in ARDS group were (59.35±3.67)mg/L and(75.38±6.27)mg/L respectively, (11.26±1.32)mg/L and(18.15±2.69)mg/L in healthy group.The difference was significant( P<0.05). And the differences of serum CC16 and SP-A levels among different degree ARDS groups were significant( P<0.05). The levels of serum CC16 in mild, moderate and severe subgroup were(38.27±16.01)mg/L, (51.25±15.63)mg/L, (84.76±13.12)mg/L and SP-A were(47.02±7.18)mg/L, (73.12±7.98)mg/L, (96.45±12.50)mg/L, which increased with disease severity. Conclusion:Serum CC16 and SP-A are increased and correlated with the severity of neonatal ARDS, which may be used as the index for evaluating the severity of neonatal ARDS in the future.
