Résumé
Objective:To investigate the rationality and surgical errors in countermeasures against difficult removal of screws so as to provide reference for standardization of technical procedures.Methods:A retrospective study was conducted to analyze the data of 99 patients who had encountered difficult removal of screws in operative removal of internal fixation at Department of Orthopaedics, Wuxi NO.9 People's Hospital Affiliated to Suzhou University from January 2018 to May 2022. There were 62 males and 37 females with an average age of 38.8±14.7 years. Their internal fixation time ranged from 7 months to 11 years. The irrationality was defined as insufficient preoperative preparation or a countermeasure that failed to follow the surgical indications or scientific principles of minimal injury or priority of simplicity. A surgical error was defined as unnecessary injury, failed removal or complications related to operation. Cases of irrationality and surgical errors were analyzed to find associations between them.Results:The operative removal was successful in 92 cases and failed in 7 cases. Of the patients who experienced difficult removal of screws, irrationality was found in 26.3% (26/99) and a surgical error or errors occurred in 28.3% (28/99). In the patients with countermeasure irrationality, the incidence of surgical errors was 53.9% (14/26) while in those without countermeasure irrationality, the incidence of surgical errors was 19.2% (14/73), showing a statistically significant difference ( χ2=11.360, P<0.001). In the patients with surgical errors, the incidence of countermeasure irrationality was 64.3% (18/28) while in the patients without surgical errors, the incidence of countermeasure irrationality was and 11.3% (8/71), showing a statistically significant difference ( χ2=29.148, P<0.001). In the patients with failed removal, the rate of countermeasure irrationality was 85.71% (6/7) while in those with successful removal, the rate of countermeasure irrationality was 21.7% (20/92), showing a statistically significant difference ( χ2=13.748, P<0.001). Conclusions:Close relationships exist between countermeasure irrationality, surgical errors and failed removal. The higher proportion of countermeasure irrationality, the higher possibility of surgical errors. Therefore, following the rationality principle may avoid or reduce surgical errors in difficult removal of screws.

Objective:To study the complications and prognosis of extremely premature infants(EPIs) with gestational age (GA) <28 w.Methods:From January 2016 to December 2020, EPIs with GA <28 w admitted to NICU of our hospital were retrospectively studied. Clinical data of the infants and their mothers during pregnancy were reviewed. According to the prognosis, the infants were assigned into the survival group, the death group and the withdrawal group. According to GA, the infants were assigned into <26 w goup, 26~26 +6 w group, ≥27 w group. According to birth weight (BW), the infants were assigned in to ≤750 g group, 750~999 g group and ≥1 000 g group. SPSS 26.0 was used for data analysis. Results:A total of 265 EPIs were included, 122 (46.0%) in the survival group, 47 (17.7%) in the death group and 96 (36.2%) in the withdrawal group. GA and BW of the survival group were significantly higher than the death group and the withdrawal group ( P<0.05). The incidences of tracheal intubation (92.2%) and pulmonary hemorrhage (42.2%) in the death group were the highest among the three groups. The survival group had the highest application of prenatal glucocorticoids (80.3%) and pulmonary surfactants (99.2%) ( P<0.05). In the survival group, the top 3 common complications were bronchopulmonary dysplasia (BPD) (68.0%), pulmonary infections (65.6%) and neonatal sepsis (34.4%). The survival rate increased with GA and BW. Conclusions:The survival rate of EPIs is closely correlated with GA and BW. EPIs with pulmonary hemorrhage and tracheal intubation have poor prognosis. Prenatal glucocorticoids and pulmonary surfactant may improve clinical outcome. BPD and pulmonary infections are common complications of surviving EPIs.

Objective:To evaluate the practical effects of perioperative diet optimization in pediatric fracture surgery, and explore the clinical efficacy and application value of circular management combined with diet optimization.Methods:Totally 76 children with selective fracture surgery were selected from May 2020 to October 2020 admitted to Wuxi 9th People′s Hospital Affiliated to Soochow University. They were divided into experimental group (38 cases) and control group (38 cases) by random number table method. Experimental group conducted circular management combined with diet optimization for nursing, while control group used only simple diet optimization management. The time and the amount of fasting before and after operation of two groups were recorded, and the compliances of two groups were evaluated according to the total amount of intake. The incidence of subjective adverse feelings, including hunger, thirst, dizziness, fatigue and nausea, were observed. And the satisfactions of patients with nursing management were also evaluated.Results:The preoperative fasting time, preoperative drinking prohibition time, postoperative diet recovery time were (8.25 ± 1.56), (2.76 ± 0.69), (1.17 ± 0.58) h in experimental group, and (9.79 ± 2.51), (3.47 ± 1.18), (1.50 ± 0.80) h in control group, and the differences were statistically significant ( t=-3.21, -3.17, -2.07, all P<0.05). The compliance rates to nursing and fasting before and after operation in control group were 57.9% (22/38), 65.8% (25/38), 76.3% (29/38) and 81.6% (31/38) respectively, which were significantly lower than all 100.0% (38/38) in experimental group ( P<0.05). During preoperative period (hunger), postoperative period when allowing intake (hunger, thirst, dizziness, feebleness) and 6 hours after intake (thirst, feebleness), the incidences of subjective adverse feelings in experimental group were statistically lower than those in control group ( Z values were -3.17- -1.97, all P<0.05). The satisfaction to dietary nursing management in experimental group was (93.82 ± 4.57) scores, which remained higher than (87.24 ± 6.65) scores in control group, and the difference was statistically significant ( t=5.03, P<0.01). Conclusions:Single perioperative diet optimization can easily be affected by the unstable clinical compliance of traumatic children, resulting in a low implementation rate. The combination of circular management and diet optimization can improve the intervention implementation and treatment compliance, shorten the time of diet prohibition, accelerate the postoperative recovery, and reduce the occurrence of perioperative adverse reactions.

Objective:To compare in vivo versus in vitro fabrication of bone cement spacers in the treatment of bone defects by Masquelet technique. Methods:The data of 128 patients were analyzed retrospectively who had been treated for bone defects by Masquelet technique at Department of Orthopedics, Wuxi No. 9 People’s Hospital from January to August 2019. They were 74 males and 54 females, aged from 13 to 77 years. Their bone defects were traumatic in 54 cases and infectious in 74 cases. In 76 of them ( in vivo group), after a bone cement spacer was implanted into a bone defect during its dough phase, it was fabricated in vivo to form a cylindrical structure which was as large as or slightly larger than the defect size. In the other 52 cases ( in vitro group), before a bone cement spacer was implanted into a bone defect, it was fabricated in vivo during its dough phase into a cylindrical or block or bead chain or spherical form which was naturally solidificated at room temperature. The 2 groups were compared in terms of spacer filling time, bone healing time, delayed healing rate, infection control rate, spacer removal time, incidence of induced membrane or broken end bone lesion, as well as upper limb function evaluated by the Disability of the Arm, Shoulder and Hand Questionnaire (DASH) and the Paley lower limb grading at the last follow-up. Results:The 2 groups were comparable because there was no significant difference between them in gender, age, ratio of infected to non-infected cases, combined injuries, comorbidities or number of operations ( P>0.05). All the patients were followed up for 12 to 50 months (mean, 18.6 months). There were no significant differences between the 2 groups in spacer filling time, bone healing time, delayed healing rate, infection control rate or functional recovery for upper or lower limbs or for large or small bone defects (all P>0.05). In the in vivo group, for upper and lower limbs and for large and small bone defects respectively, the spacer removal time [(3.6±1.0) min, (4.1±1.1) min, (4.0±1.1) min and (3.9±1.0) min] and the incidence of induced membrane or broken end bone lesion [48.1%(13/27), 73.5%(36/49), 82.6%(39/46) and 66.7%(20/30)] were significantly longer or higher than those in the in vitro group [all (0.4±0.2) min; 3.2%(1/31), 9.5%(2/21), 0 (0/21) and 0 (0/31)] (all P<0.05). Conclusions:In the treatment of bone defects by Masquelet technique, in vivo and in vitro fabrication of bone cement spacers may lead to similar therapeutic effects. In vivo fabrication may be more suitable for lower limb, large or unstable bone defects but the spacer is not easy to remove and the induced membrane or bone ends are likely to get injured while in vitro fabrication may be more suitable for partial, small or upper limb defects because it may produce a variously shaped spacer.

Résumé
High-fat diet-induced insulin resistance rat model was assessed by euglycemic-hyperinsulinemic clamp technique.Compared with the control group,the vaspin mRNA expression in adipose tissue was significantly decreased in insulin resistant rats induced by high-fat diet( P<0.05 ),which was increased by metformin( P<0.05 ).These data indicate that metformin may ameliorate insulin resistance in rats via upregulating vaspin mRNA expression.
Résumé
After 4 weeks old male Sprague-Dawley rats were fed with normal diet and high-fat diet for 10 weeks,the rats were treated with metformin (200 mg/kg) for 6 weeks. Insulin sensitivity was determined by hyperinsulinemic-euglycemic clamp technique.Realtime PCR and western blot were used to measure mRNA and protein levels of chemerin in perirenal adipose tissue of rats.The results showed that the expressions of chemerin mRNA and protein were higher in high-fat diet-induced insulin resistant rats compared with rats fed with normal diet ( both P<0.05 ),and these incremental findings were diminished by metformin treatment ( both P<0.01 ).The levels of chemerin mRNA and protein were correlated well with the epididymis fat mass index.
