Objective:To identify the risk factors affecting the healing of defective bony nonunion.Methods:The studies reporting the risk factors for healing of defective bony nonunion between January 2000 and March 2022 were retrieved by computer from the VIP, Wanfangdata, CNKI, Web of Science, PubMed, and Medline databases. The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of the included studies. the RevMan 5.3 software was used to perform a meta-analysis of the general factors, injuries and surgical-related factors affecting the healing of defective bony nonunion.Results:Included in this Meta analysis were 17 studies with 1,236 patients. The NOS score of the included studies was from 5 to 8. The meta-analysis showed the following: age ( MD=-4.27, 95% CI: -8.29 to 2.91, P < 0.01), smoking ( OR=3.56, 95% CI: 2.81 to 6.32, P < 0.01), soft tissue defect ( OR=3.54, 95% CI: 2.21 to 5.69, P < 0.01), combined ipsilateral fibular fracture ( OR=4.18, 95% CI: 1.24 to 14.03, P=0.02), venous thrombosis ( OR=4.27, 95% CI: 1.05 to 17.44, P=0.04), and postoperative infection ( OR=2.96, 95% CI: 1.97 to 4.47, P < 0.01) were significant risk factors for the healing of defective bone nonunion. Minor bone defect ( SMD=-0.67, 95% CI: -1.25 to -0.10, P=0.02), proximal to distal bone transport ( OR=-0.42, 95% CI: 0.22 to 0.77, P < 0.01), short-term external fixation ( MD=-3.92, 95% CI: -7.10 to -0.73, P=0.02), and autologous bone grafting ( OR=0.39, 95% CI: 0.16 to 0.95, P=0.04) were protective factors for the healing of defective bony nonunion. Conclusions:High age (senility), smoking, soft tissue defect, ipsilateral fibular fracture, venous thrombosis, and postoperative infection are risk factors affecting the healing of defective bony nonunion. Minor bone defect, proximal to distal bone transport, short-term external fixation, and autologous bone grafting are protective factors affecting the healing of defective bony nonunion. Surgeons can predict early the prognosis of patients with defective bony nonunion based on the above factors.

Objective:To study the clinical and genetic characteristics of Wiskott-Aldrich syndrome (WAS) in neonates.Methods:From January 2016 to August 2022, neonates with WAS admitted to the neonatal department of our hospital were studied.Their clinical features, laboratory findings, genetic characteristics and clinical outcomes were retrospectively analyzed.Results:A total of 11 neonates(all male) were included. The mothers of 3 neonates had thrombocytopenia during pregnancy. The presenting symptoms included isolated bloody stool (4 cases), jaundice (3 cases), bloody stool with petechiae, bloody stool with hematemesis, cough and fever(1 case each). Eczema appeared from 6 d to 3 months after birth and in 6 cases during the neonatal period. None of the 11 cases had serious infection during the neonatal period. 9 cases had infection from 8 d to 5 months and 2 cases had not been infected until the last follow-up. Genetic sequencing showed four frameshift variants(c.30dupC, c.205dupT, c.1340_1343dupC and c.673_674delA), four nonsense variants(c.37C>T, c.295C>T, c.889C>T and c.823G>T) and three missense variants(c.134C>T, c.397G>A and c.341T>C). Pedigree verification of variants found 10 cases were inherited from their mothers and 1 case was de novo variant.Conclusions:WAS is characterized by bloody stool and eczema in the neonatal period, mostly without serious infections and lacking specific manifestations. Genetic screening for early identification of unexplained thrombocytopenia in male newborns should be performed as early as possible.

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.

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 current status of quality of working life( QWL) among medical staffs in Minhang District,Shanghai City,and to explore the relationship between QWL and occupational stress. METHODS: A stratified sampling method was used to select 522 medical staffs in Minhang District,Shanghai City. The QWL and occupational stress were assessed using the Quality of Working Life Scale and the Effort-Reward Imbalance Questionnaire,respectively.RESULTS: The total score of QWL of medical staffs was( 97. 7 ± 13. 8),and the detection rate of high occupational stress was34. 7%( 181/522). The total QWL score of medical workers in the high occupational stress group was lower than that in the low occupational stress group( P < 0. 01). The results of multivariable logistic regression analysis showed that occupational stress and average weekly working time were risk factors of reduction in QWL( P < 0. 01). CONCLUSION: Occupational stress is the influencing factor of QWL. The increased occupational stress may reduce the QWL of medical personnel.
