ABSTRACT
Vibrio parahaemolyticus, the main pathogen causing seafood related food poisoning worldwide, has strong biofilm formation ability. ToxR is a membrane binding regulatory protein, which has regulatory effect on biofilm formation of V. parahaemolyticus, but the specific mechanism has not been reported. c-di-GMP is an important second messenger in bacteria and is involved in regulating a variety of bacterial behaviors including biofilm formation. In this study, we investigated the regulation of ToxR on c-di-GMP metabolism in V. parahaemolyticus. Intracellular c-di-GMP in the wild type (WT) and toxR mutant (ΔtoxR) strains were extracted by ultrasonication, and the concentrations of c-di-GMP were then determined by enzyme linked immunosorbent assay (ELISA). Three c-di-GMP metabolism-related genes scrA, scrG and vpa0198 were selected as the target genes. Quantitative real-time PCR (q-PCR) was employed to calculate the transcriptional variation of each target gene between WT and ΔtoxR strains. The regulatory DNA region of each target gene was cloned into the pHR309 plasmid harboring a promoterless lacZ gene. The recombinant plasmid was subsequently transferred into WT and ΔtoxR strains to detect the β-galactosidase activity in the cellular extracts. The recombinant lacZ plasmid containing each of the target gene was also transferred into E. coli 100λpir strain harboring the pBAD33 plasmid or the recombinant pBAD33-toxR to test whether ToxR could regulate the expression of the target gene in a heterologous host. The regulatory DNA region of each target gene was amplified by PCR, and the over-expressed His-ToxR was purified. The electrophoretic mobility shift assay (EMSA) was applied to verify whether His-ToxR directly bound to the target promoter region. ELISA results showed that the intracellular c-di-GMP level significantly enhanced in ΔtoxR strain relative to that in WT strain, suggesting that ToxR inhibited the production of c-di-GMP in V. parahaemolyticus. qPCR results showed that the mRNA levels of scrA, scrG and vpa0198 significantly increased in ΔtoxR strain relative to those in WT strain, suggesting that ToxR repressed the transcription of scrA, scrG and vpa0198. lacZ fusion assay showed that ToxR was able to repress the promoter activities of scrA, scrG and vpa0198 in both V. parahaemolyticus and E. coli 100λpir. EMSA results showed that His-ToxR was able to bind to the regulatory DNA regions of scrA and scrG, but not to the regulatory DNA region of vpa0198. In conclusion, ToxR inhibited the production of c-di-GMP in V. parahaemolyticus via directly regulating the transcription of enzyme genes associated with c-di-GMP metabolism, which would be beneficial for V. parahaemolyticus to precisely control bacterial behaviors including biofilm formation.

Objective:To explore the clinical effect of open reduction in the treatment of Tile C pelvic fracture combined with acetabular fracture in a specific sequence.Methods:Retrospectively analyzed the clinical data of 53 patients with Tile C type pelvic fracture combined with acetabular fracture from January 2014 to January 2019, and were divided into specific sequence group and non-specific sequence group according to the sequence of intraoperative reduction. A total of 29 cases were observed in the specific sequence group, including 20 males and 9 females; aged 43.8±14.8 years old (18-71 years), and the fractures were reduced in the sequence of "inside and out, then up and down" during the operation. There were 24 cases in the non-specific sequence group, including 14 males and 10 females; aged 44.4±14.7 years old (18-69 years), and fracture reduction was not performed in this sequence during the operation. According to the type of pelvic and acetabular fracture injury, we choose the appropriate position and surgical approach. After open reduction, the fracture was fixed with internal plants. The intraoperative blood loss, operation time, visual analogue scale (VAS) score were compared between the two groups. The quality of fracture reduction was evaluated by Matta score, pelvic fracture function recovery was evaluated by Majeed score, and acetabular fracture was evaluated by hip joint modified Merle d'Aubigné-Postel score.Results:There was no statistically significant difference in general data between the two groups before operation ( P>0.05), which was comparable. The intraoperative blood loss of the specific sequence group and the non-specific sequence group were 1 031.1±513.7 and 1 406.3±738.1 ml, and the operation time was 3.5±1.0 and 4.8±1.4 h; The differences between the two groups were statistically significant ( P<0.05). 53 patients were followed up for 14.8±1.6 months (12-18 months) after operation. The average postoperative VAS scores of specific sequence group and non-specific sequence group were 1.3±1.1 and 1.5±1.3 respectively, and there was no statistically significant difference. The effectiveness of the pelvic fracture Matta score standard was evaluated in the specific sequence group: excellent in 22 cases, good in 5 cases, fair in 2 cases, excellent and good rate was 93.1%; non-specific sequence group excellent in 10 cases, good in 6 cases, fair in 5 cases, poor in 3 cases, excellent and good rate was 66.7%, the difference was statistically significant ( P<0.05). Matta score of acetabular fracture: 21 cases were excellent in specific sequence group, 5 cases were good, 3 cases were poor, excellent and good rate was 89.7%; 9 cases were excellent in non-specific sequence group, 8 cases were good, 7 cases were poor, excellent and good rate was 70.8 %, the difference is statistically significant ( P<0.05). The results of the last follow-up pelvic fractures were evaluated by Majeed score: 20 cases were excellent in the specific sequence group, 7 were good, 2 were fair, excellent and good rate was 93.1%; 10 were excellent in the non-specific sequence group, 5 were good, 5 were fair, and 4 were poor, excellent and good rate was 62.5%, the difference was statistically significant ( P<0.05). At the last follow-up, the modified Merle d'Aubigné-Postel score was used to evaluate the efficacy: 20 cases were excellent in the specific sequence group, 5 were good, 4 were fair, the excellent and good rate was 86.2%; In the non-specific sequence group, 9 cases were excellent, 7 cases were good, 4 cases were fair, and 4 cases were poor, excellent and good rate was 66.7%, the difference was statistically significant ( P<0.05). During the follow-up period, none of the patients in the two groups developed fracture nonunion, heterotopic ossification, iatrogenic neurovascular injury, and femoral head necrosis. Trauma arthritis occurred in 4 patients in the non-specific sequence group. Conclusion:"Inside and out, then up and down" sequential reduction of Tile C pelvis combined with acetabular fracture can significantly shorten the operation time and reduce the amount of intraoperative blood loss. The surgical procedure is reasonable, which helps to improve the quality of fracture reduction and promote the functional recovery of patients.
ABSTRACT
Objective:To explore the clinical diagnosis and treatment experience of pelvic fracture complicated with anterior sacroiliac joint dislocation.Methods:The data of 19 patients with pelvic fracture and anterior sacroiliac joint dislocation admitted from June 2013 to September 2019 were retrospectively analyzed. There were 12 males and 7 females; aged 9-67 years, with an average of 28.0 years. There were 11 cases of traffic accident injury, 6 of falling injury and 2 of crashing injury caused by machine extrusion. According to the Tile classification, there were 8 cases of type C1, 2 of type C2, and 9 of type C3; 6 cases of modified mangled extremity severity score (MESS) were greater than or equal to 7, of which 2 cases underwent hip amputation, 4 cases underwent king-steelquis semipelvectomy. 13 cases underwent limb-salvage surgery, of which 3 cases underwent external fixation surgery, and the remaining 10 cases underwent open reduction and internal fixation with steel plate. The reduction quality was evaluated according to the Matta imaging criteria of pelvis, the pain was evaluated according to the visual analogue scale (VAS), and the pelvic function was evaluated according to the Majeed score.Results:The operation time was 2 to 4 hours, with an average of 3.2 hours; the intraoperative blood loss was 400 to 1 200 ml, with an average of 768.4 ml. The 18 surviving patients were followed up for 6 to 24 months, with an average of 11.6 months. One of the 6 amputation patients died one week after the operation due to septic shock and multiple organ failure. The overall survival rate of the patients was 94.7% (18/19), and the amputation rate was 31.6% (6/19). The pelvic fractures of the 18 surviving patients were all healed, and the fracture healing time was 3 to 6 months, with an average of 4.2 months. No delayed union or nonunion occurred. At the last follow-up of the 18 surviving patients, the VAS was 2.4±1.9 points (range, 0-6 points). Among them, there were no pain in 3 cases, mild pain in 9 cases and moderate pain in 6 cases. At the last follow-up, 13 patients undergoing limb salvage treatment evaluated the quality of reduction according to Matta imaging criteria. Among them, 6 cases were excellent, 4 were good, 2 were fair, and 1 was poor. The excellent and good rate was 76.9% (10/13). The Majeed functional score was 81.8±11.9 points (range, 53-95 points). Among them, 6 cases were excellent, 5 were good, 1 was fair, and 1 was poor. The excellent and good rate was 84.6% (11/13). In the limb salvage treatment group, 4 patients with lumbosacral nerve injury caused limited hip joint movement function, and unilateral lower limb sensation and movement were weakened. After neurolysis and nutritional support treatment, the patient's sensorimotor function was significantly improved.Conclusion:The mortality and disability rate of pelvic fractures combined with anterior sacroiliac joint dislocation is high. In order to save the patient's life, early diagnosis of limb injury and early surgical intervention should be performed. If necessary, hip disarticulation or king-steelquis should be selected.
ABSTRACT
Objective:To investigate the application value of magnetic resonance neurography (MRN) in pelvic fractures with lumbosacral plexus injury.Methods:From January 2014 to June 2020, data of 9 patients with pelvic fractures combined with lumbosacral plexus injury who were diagnosed with MRN and were performed surgical treatment were analyzed retrospectively. Among them, there were 8 males and 1 female, aged from 18 to 54 years, with an average age of 40.6±11.0 years. There were 2 fresh fractures within 3 weeks and 7 old pelvic fractures in 9 patients. According to AO classification, there were 6 cases of C1.3 type, 3 cases of C3 type. According to Denis classification of sacral fracture, there were 8 cases of Denis II type, 1 case of Denis III. Gibbons classification of nerve injury: 2 cases of grade II, 4 cases of grade III, 3 cases of grade IV; According to the criteria by the Nervous Injury Committee of British Medical Research Council (BMRC): 2 cases of M1, 3 cases of M2, 2 cases of M3, 2 cases of M4. Before the operation, the MRN technology was used to accurately locate the location and extent of the lumbosacral nerve injury, and nerve exploration release or internal fixation combined with nerve exploration release was employed for treatment.Results:All 9 patients underwent surgery successfully. The operation time ranged from 150 to 360 min, with an average of 217.8±63.8 min; intraoperative blood loss ranged from 200 to 1 100 ml, with an average of 388.9±293.4 ml. All patients were followed up for 21.6±19.3 months. All the fractures were healed, and the healing time was 12.7±2.2 months (range, 10-18 months). At the last follow-up, Gibbons classification of nerve injury: 3 cases of grade I, 5 cases of grade II, and 1 case of grade III. According to the criteria of BMRC: the muscle strength achieved M5 in 6 cases, M4 in 2 cases, M3 in 1 case. One patient developed a urinary system infection 2 months after discharge and recovered after treatment.Conclusion:MRN technique can assist the surgeon to fully understand the compression and traction damage of the lumbosacral nerve by the fracture before the operation, and make clear qualitative and localized diagnosis of the nerve damage, making the operation more precise and minimally invasive, which is a supplement to the traditional diagnosis method of lumbosacral plexus injury.
ABSTRACT
Objective:To construct a risk prediction model for attention deficit hyperactivity disorder (ADHD) in children.Methods:A total of 1 000 children patients diagnosed with ADHD who received treatment in the Department of Pediatrics, the Third People's Hospital of Yuyao, China between January 2017 and June 2020 were included in the ADHD group. Additional 1 000 school-age children who concurrently received health examination were included in the control group. Questionnaire surveys were performed among the subjects' close relatives. The risk prediction models for ADHD were constructed.Results:Mother's irritability, abnormal emotion during pregnancy, father's history of ADHD symptoms, mother's smoking, rearing style and fetal distress were independent risk factors for ADHD. The area under the ROC curve of prediction model application was 0.929 (0.894-0.964).Conclusion:The constructed risk prediction models for ADHD have good performance in the prediction of ADHD. Children at high risk of ADHD should be followed up as early as possible. Parents' health education and parenting intervention should be strengthened to prevent the occurrence of ADHD.
ABSTRACT
Objective:To investigate the risk factors for nosocomial infection in older adult inpatients in some psychiatric hospitals in Ningbo of Zhejiang Province.Methods:The clinical data of 832 inpatients who received treatment in Ningbo Kangning Hospital and the Third Branch of Healthcare Group of Xiangshan Hospital of Traditional Chinese Medicine were retrospectively analyzed. These patients were divided into one infection group ( n = 45) and one non-infection group ( n = 787). The risk factors for nosocomial infection were analyzed. Results:Univariate analysis results showed that there were significant differences in age, disease type, primary pulmonary infection, time of antibiotics use, length of hospital stay, suffering from mental diseases, and use of urinary catheters ( χ2 = 10.721, 18.127, 12.183, 67.127, 56.326, 65.114, 27.153, all P < 0.001). Multivariate analysis showed that age ≥ 75 years, disease type, primary pulmonary infection, time of antibiotics use, length of hospital stay, suffering from mental diseases, and use of urinary catheter were independent risk factors for nosocomial infection in older adult inpatients ( OR = 3.360, 3.777, 5.238, 3.364, 3.939, 4.428, all P < 0.001). Conclusion:Age ≥ 75 years, disease type, primary pulmonary infection, time of antibiotics use, length of hospital stay, suffering from mental diseases, and use of urinary catheters are independent risk factors for nosocomial infection in older adult inpatients in some psychiatric hospitals in Ningbo of Zhejiang Province.
ABSTRACT
High-energy trauma-induced pelvic fractures often cause hemodynamic instability which is the first cause of death in their victims. Rapid and effective control of massive bleeding in patients with pelvic fracture is still a clinical challenge for which there have been no well-accepted standards for clinical diagnosis and treatment. Although the development of pelvic packing and angiographic embolization has raised the survival rate for patients undergoing massive hemorrhage after pelvic fracture, their martality rate still fluctuates between 30% and 50%. This review introduces the recent advances made in pelvic packing and angiographic embolization used in clinical emergency treatment of massive hemorrhage following pelvic fracture, hoping to provide useful knowledge for clinicians who may handle this condition.
ABSTRACT
Objective:To explore the clinical effect of iliolumbar fixation combined with internal fixation (INFIX) and plate fixation in treatment of Tile type C3 pelvic fracture in obese patients.Methods:A retrospective case series study was conducted to analyze the data of 14 obese patients with Tile type C3 pelvic fracture admitted to Shandong Provincial Hospital from March 2014 to June 2019, including 10 males and 4 females, aged 14-46 years [(37.1±8.9)years]. The body mass index was 28.0-38.6 kg/m 2 [(30.7±3.4)kg/m 2]. All patients were treated by posterior iliolumbar fixation, followed by INFIX and plate fixation in the anterior ring. The operation time, intraoperative blood loss, and fracture healing time were observed. The visual analogue scale (VAS) was used to evaluate the improvement of limb pain before operation, immediately after operation, at postoperative 3 months and 6 months, and at last follow-up. The fracture reduction was evaluated by Matta criteria, and function was evaluated by Majeed functional score at last follow-up. Postoperative complications were observed. Results:All patients were followed up for 6-18 months [(13.5±4.0)months]. The operation time was 4-10.5 hours [(6.9±2.3)hours], and the intraoperative blood loss was 800-2 200 ml [(1 071.4±357.4)ml]. All fractures were healed at 12-32 weeks [(19.1±5.9)weeks]. The VAS was (8.2±1.0)points preoperatively, (5.9±0.8)points immediately after surgery, (3.9±0.9)points, (3.0±0.8)points and (1.9±1.1)points respectively at postoperative 3 months and 6 months, and at last follow-up (all P<0.01). At last follow-up, according to the Matta criteria, the results were excellent in 10 patients, good in 2, fair in 1, poor in 1, with the excellent and good rate of 86%. At last follow-up, the results for Majeed functional score were excellent in 8 patients, good in 3, fair in 2 and poor in 1, with the excellent and good rate was 79%. One patient had venous thrombosis of lower extremities, with good therapeutic effect after anticoagulation therapy. Two patients had lateral femoral cutaneous nerve injury and recovered gradually after the internal fixation was removed. Conclusions:Iliolumbar fixation combined with INFIX plus plate fixation in the treatment of obese patients with Tile type C3 pelvic fracture has the advantages of good fracture healing, pain relief, satisfactory pelvic reduction and function recovery, and less postoperative complications. The procedure is an alternative surgical plan for treatment of Tile type C3 pelvic fracture in obese patients.

ABSTRACT
Objective@#To compare the clinical efficacy of the preserving insertion point of the rectus abdominis-Pfannenstiel approach with traditional Pfannenstiel approach in the treatment of pelvic anterior ring injuries.@*Methods@#A retrospective analysis was performed on 43 cases with pelvic anterior ring injuries treated from September 2008 to February 2016. Among them, 20 cases were treated with the preserving insertion point of the rectus abdominis-Pfannenstiel approach (modified approach group) including 14 males and 6 females, aged 18-58 years, with an average age of 36.9 years. According to Tile classification of pelvic fractures, there were 8 cases of B1 type, 4 cases of B2 type, 2 cases of B3 type, 4 cases of C1 type and 2 cases of C2 type. And 23 cases were treated with traditional Pfannenstiel approach (traditional approach group, 16 cases of males and 7 cases of females, aged 19-59 years, with an average age of 36.8 years). Tile classification of pelvic fractures: 9 cases of B1, 4 cases of B2, 3 cases of B3, 4 cases of C1 and 3 cases of C2). The operative time, intraoperative blood loss, postoperative hospital stay, postoperative reduction, postoperative functional and complications were compared between the two groups.@*Results@#43 patients were followed up for 12-40 months, with an average of 20.5 months. All fractures healed in 8-20 weeks, with an average time of 10 weeks. Duration of anterior approach: 119.0±18.3 min in the modified approach group and 93.7±17.8 min in the traditional approach group (t=4.597, P< 0.05). Intraoperative blood loss: 206.0±38.2 ml in the modified approach group and 252.4±46.1 ml in the traditional approach group (t=-3.560, P< 0.05). Postoperative hospital stay: 14.5±3.0 d in the modified approach group, and 20.0±4.4 d in the traditional approach group (t=-4.775, P< 0.05). Postoperative reduction was evaluated according to the Matta reduction criteria, among which 15 cases were excellent and 5 cases were good in the modified approach group; 17 cases were excellent and 6 cases were good in the traditional approach group. According to the Majeed score, the postoperative function of pelvic fracture was excellent in 10 cases, good in 7 cases, and acceptable in 3 cases, with an excellent and good rate of 85.0% (17/20). There were 11 excellent cases, 8 good cases and 4 fair cases in the traditional approach group, with an excellent and good rate of 82.6% (19/23). There was no statistically significant difference between the two groups (χ2=0.04, P >0.05).

ABSTRACT
Objective To compare the clinical efficacy of the preserving insertion point of the rectus abdominis?Pfannen?stiel approach with traditional Pfannenstiel approach in the treatment of pelvic anterior ring injuries. Methods A retrospective analysis was performed on 43 cases with pelvic anterior ring injuries treated from September 2008 to February 2016. Among them, 20 cases were treated with the preserving insertion point of the rectus abdominis?Pfannenstiel approach (modified approach group) including 14 males and 6 females, aged 18-58 years, with an average age of 36.9 years. According to Tile classification of pelvic fractures, there were 8 cases of B1 type, 4 cases of B2 type, 2 cases of B3 type, 4 cases of C1 type and 2 cases of C2 type. And 23 cases were treated with traditional Pfannenstiel approach (traditional approach group, 16 cases of males and 7 cases of females, aged 19-59 years, with an average age of 36.8 years). Tile classification of pelvic fractures: 9 cases of B1, 4 cases of B2, 3 cases of B3, 4 cases of C1 and 3 cases of C2). The operative time, intraoperative blood loss, postoperative hospital stay, postoperative reduc?tion, postoperative functional and complications were compared between the two groups. Results 43 patients were followed up for 12-40 months, with an average of 20.5 months. All fractures healed in 8-20 weeks, with an average time of 10 weeks. Duration of anterior approach: 119.0±18.3 min in the modified approach group and 93.7±17.8 min in the traditional approach group (t=4.597, P<0.05). Intraoperative blood loss: 206.0±38.2 ml in the modified approach group and 252.4±46.1 ml in the traditional ap? proach group (t=-3.560, P<0.05). Postoperative hospital stay: 14.5±3.0 d in the modified approach group, and 20.0±4.4 d in the traditional approach group (t=-4.775, P<0.05). Postoperative reduction was evaluated according to the Matta reduction criteria, among which 15 cases were excellent and 5 cases were good in the modified approach group; 17 cases were excellent and 6 cases were good in the traditional approach group. According to the Majeed score, the postoperative function of pelvic fracture was excel?lent in 10 cases, good in 7 cases, and acceptable in 3 cases, with an excellent and good rate of 85.0% (17/20). There were 11 excel?lent cases, 8 good cases and 4 fair cases in the traditional approach group, with an excellent and good rate of 82.6% (19/23). There was no statistically significant difference between the two groups (χ2=0.04,P >0.05). Complications: 2 cases of internal fixation loosening and 2 cases of coital pain occurred in the modified approach group after surgery, with a complication rate of 20.0% (4/20). Postoperatively, 1 case of superficial infection, 1 case of pulmonary infection, 1 case of internal fixation loosening, 1 case of screw broken and 4 cases of coital pain occurred in the traditional approach group, with a complication rate of 34.8% (8/23). Conclu?sion Both approaches can achieve satisfactory results in the treatment of anterior pelvic ring injury. The preserving insertion point of the rectus abdominis?Pfannenstiel approach for the treatment of anterior pelvic ring injuries has the advantages of less bleeding, faster recovery and shorter hospitalization time.
ABSTRACT
Objective To build a predictive model of depression with secondary mild cognitive impairment (MCI) in elderly patients based on current clinical diagnosis and treatment technology,and to analyze its application.Methods Elderly patients with depression hospitalized in three hospitals were consecutively included in our study from September 2013 to December 2015 for collecting relevant clinical data,and followed up for 18 months to confirm a prognosis.The follow-up results were used to predict influencing indices for secondary MCI risk,and to verify judgement effectiveness of the critical value of the relevant indices on the window of time of the secondary MCI.Results A total of 216 elderly patients with depression were included in this study,of whom 9 patients were lost to follow-up.Finally,27 patients had secondary MCI,and 180 patients had normal cognitive function during the follow-up period.Cox multiple regression analysis showed that the risk model of secondary MCI in elderly patients with depression was composed of age (HR:1.30,95 ％ CI:1.12-1.64,P =0.03),education years (HR:0.56,95 ％ CI:0.41-0.80,P =0.01),regular psychological treatment (HR:0.73,95％ CI:0.58-0.92,P=0.03),and BSSI scale (HR:1.24,95％ CI:1.08-1.56,P=0.03).Age and BSSI scale were risk factors,while education years and regular group psychotherapy were protective factors.For an elderly patient with depression who was characterized by age ≥ 72.3 years,education years ＜8.3 years,and BSSI scale ≥75.1,the window of time for secondary MCI was shorter,and these critical values of the independent factors had significant judgement effectiveness.Conclusions Age,education years,regular psychological treatment,and BSSI scale are independently influencing factors for secondary MCI in elderly patients receiving the treatment for depression.Furthermore,age ≥72.3 years,the education period ＜8.3 years,and BSSI scale ≥75.1 points are critical values of secondary MCI.
ABSTRACT
Objective To explore the application value of external fixator in obsolete hip dislocation.Methods Retrospective analysis of 9 cases of obsolete hip dislocation treated with external fixator from January 2010 to January 2017.There were 6 males and 3 females,with an average of 32.0±8.3 years old (range 19-47).The time from injury to operation was 3-9 months,with an average of 6.2± 1.9 months.The patient's limb shortening length,traction time,traction length,operation time,surgical bleeding volume,preoperative and last follow-up VAS score,Epstein score,D'Aubigne functional score were recorded.Results The length of the limb shortened 5-11cm,with an average of 6.7±2.0 cm.The preoperative traction time ranged 20-45 d,with an average of 26.9±8.2 d.The length of traction ranged 5-12 cm,with an average of 7.1±2.2 cm.The second reconstruction operation time was 2.0-4.0 hours,with an average of 2.8±0.7 h.The bleeding volume was 800-2 000ml,with an average of 1 216.7±422.8 ml.The Epstein score at the last follow-up was excellent in 4 cases,good in 4 cases and improved in 1 case.The preoperative VAS score and the final follow-up VAS score were 0.9±0.8 points and 4.6±0.9 points respectively.There was a significant difference between preoperative and postoperative VAS scores (t=8.981,P=0.000).The D'Aubigne functional scores of preoperative and final follow-up were 5.2±1.0 points and 13.1±2.0 points respectively and the difference was statistically significant (t=-12.044,P=0.000).Conclusion The external fixation in the treatment of obsolete dislocation of the hip is helpful and accepted in patients with femoral head dislocation.It is easy to carry and tract for patients and convenient for functional exercise.The external fixation makes operation simple and flexible;the traction force is strong and the effect of the femoral head reduction is obvious,the operation method is simplified and the quality of the reduction is improved.
ABSTRACT
Objective To study the effect of olanzapine combined with repetitive transcranial magnetic stimulation(rTMS) in the treatment of phonism dominated schizophrenia.Methods From August 2015 to November 2016,112 patients with phonism based schizophrenia in Ningbo Kangning Hospital were selected in the research . According to the different treatment ,the patients were divided into observation group and control group ,with 56 cases in each group.The observation group was treated with olanzapine combined with rTMS chemotherapy ,the control group was treated with olanzapine.Before and after treatment,the positive and negative symptom scale ( PANSS) score, Wisconsin Card Sorting Test ( WCST) score of the two groups were observed.The clinical efficacy was compared between the two groups.Results Before treatment,there were no statistically significant differences in PANSS score and WCST score between the two groups ( all P＞0.05).After treatment for 1 week,2 weeks,4 weeks,the PANSS scores of the two groups were significantly lower than those before treatment (F＝170.710,106.028,28.530,30.328, 25.806,10.832,203.342,372.253,all P＜0.05).The PANSS scores decreased more significantly in the observation group.After treatment for 1,2,4 weeks,the scores of positive symptoms in the observation group were (25.95 ±3.50)points, (24.72 ±4.50)points and(16.51 ±2.70)points,respectively,which were significantly lower than those in the control group[(27.27 ±2.03)points,(27.80 ±5.37)points,(19.53 ±3.07)points](t＝2.441,3.290,5.528,all P＜0.05).After treatment for 1 week,2 weeks,4 weeks,the continuous response scores in the observation group were (45.62 ±5.41)points,(44.69 ±4.91) points,(35.89 ±3.30) points,respectively,which were significantly lower than those in the control group[(50.61 ±5.35)points,(46.80 ±5.14)points,(42.70 ±5.04)points](t＝4.908, 2.221,8.459,all P＜0.05).The scores of continuous errors in the observation group were (49.47 ±4.59) points, (46.53 ±6.05) points and (36.35 ±5.18) points,respectively,which were lower than those in the control group [(83.1 ±6.58)points,(81.85 ±6.70)points and (76.86 ±76.86)points](t＝31.369,29.279,38.464,all P＜0.05).After treatment for 1 week,2 weeks,the classification scores in the observation group were (4.21 ±2.03) points and (5.35 ±2.23) points,respectively,which were significantly higher than those in the control group [(3.35 ±1.24)points and (3.95 ±1.24)points] (t＝2.705,4.106,all P＜0.05).The effective rate was 91.0%in the observation group ,which was 89.2%in the control group,there was no statistically significant difference (χ2＝0.022,P＞0.05).Conclusion Olanzapine combined with rTMS is effective in the treatment of schizophrenia ,and olanzapine combined with rTMS is more effective in improving the cognitive ability of patients than olanzapine alone .
ABSTRACT
Objective To report the effects of surgical treatment of old die-punch fractures of the distal radius.Methods A retrospective study of case series was made of the 21 old die-punch fractures of the distal radius which had been surgically treated from January 2012 to January 2017 at Department of Orthopaedics,Shandong Provincial Hospital.There were 13 males and 8 females,aged from 34 to 63 years (average,46.9 years).According to the preoperative definite diagnoses by the X-ray and CT images,there were 14 metacarpal compression fractures and 7 dorsal compression fractures.The palmar approach was used in 13 cases,the dorsal approach in 7 and the combined approach in one.Autogenous iliac bone grafting was performed for all the cases.Their preoperative and postoperative Cooney scoring and visual analogue scale (VAS) of the wrist,and postoperative complications as well,were observed and recorded.Results This cohort was followed up for 8 to 14 months (average,9.2 months).All their postoperative wounds healed by the first intention.Their Cooney functional scores of the wrist were,respectively,58.5 ± 4.2 and 84.0 ± 3.1 points preoperatively and at the final follow-up,and their corresponding VAS scores 7.6 ± 0.9 and 3.4 ± 1.3 points,showing significant differences between preoperation and the final follow-up (P ＜ 0.05).Carpal arthritis was observed in one case.Conclusion For old die-punch fractures of the distal radius,surgical treatment can obviously reduce pain,improve function of the wrist and enhance the quality of life of the patients.
ABSTRACT
Objective To evaluate clinical outcomes of the Kocher-Langenbeck (K-L) approach combined with partial proximal Watson-Jones incision for the treatment of acetabular fractures involving the weight-bearing area.Methods From January 2012 to January 2017,20 patients were treated by the K-L approach combined with partial proximal Watson-Jones incision for acetabular fracture involving the weight-bearing acetabular dome.They were 13 males and 7 females,with an average age of 40.7 years (range,from 22 to 67 years).According to the Letournel-Judet classification,there were 8 posterior wall fractures,one transverse fracture,one T-shaped fracture,one transverse and posterior wall fracture,3 posterior column and posterior wall fractures,and 6 double-column fractures.All patients received open reduction and internal fixation with plates and screws.The outcomes of reduction were evaluated at follow-ups according to the Matta criteria.The hip function was evaluated according to the modified Merle d'Aubigne-Postel criteria and the abductor strength by the American Medical Research Council criteria at final follow-ups.Results All the 20 patients were followed up for an average of 8.2 months (range,from 7 to 21 months).They all obtained bony union after 10 to 18 weeks (average,11.4 weeks).No fracture displacement,internal fixation loosening or deep infection occurred.According to the Matta criteria,anatomic reduction was achieved in 13 cases,satisfactory reduction in 6 cases,and unsatisfactory in one (a satisfactory rate of 95％).The modified Merle d'Aubigne-Postel scoring for the hip function at the final follow-ups yielded 9 excellent cases,7 good cases,3 fair cases and one poor case (an excellent to good rate of 80％).Ectopic ossification of Brooker grade Ⅰ occurred in one case.The abductor strength was rated as grade Ⅳ in 3 cases and as grade Ⅴ in 17.Conclusions In the treatment of acetabular fractures involving the acetabular dome,the K-L approach combined with partial proximal Watson-Jones incision can increase the operation view of the weight-bearing area,enhance the anatomic matching of femoral head and acetabular roof,and reduce the difficulties in reduction and fixation.
