New application of endobutton suspension plate in hallux valgus deformity / 中国组织工程研究

BACKGROUND: Hallux valgus is a complex deformity. There is no gold standard for the treatment of hallux valgus. Osteotomy is highly recommended at present, but there are many complications. Whether we can correct hallux valgus without osteotomy Is a new attempt In our group. OBJECTIVE: To explore the efficacy of an Endobutton suspension plate treatment for hallux valgus deformity. METHODS: From April 2013 to August 2018 at Department of Orthopedics, Changzhou Tumor Hospital Affiliated to Soochow University, 26 cases of hallux valgus were treated with Endobutton suspension plate, without osteotomy. All patients signed the Informed consents and the study was approved by the hospital ethics committee. The hallux valgus angle and angle between metatarsal 1 and 2 were detected preoperatively and postoperatively. The American Orthopaedic Foot & Ankle Society score was detected at 12 months postoperatively. RESULTS AND CONCLUSION: (1) All patients were followed up from 8 to 38 months. (2) The hallux valgus angle (28.95±4.12)° and angle between metatarsal 1 and 2 (15.82±1.81)° preoperatively were significantly decreased to (14.15±3.60)° and (7.88±0.90)° postoperatively (both P < 0.01). (3) The American Orthopaedic Foot & Ankle Society score at 12 months after surgery (89.15±7.81) was significantly higher than that at baseline (62.08±7.10) (P < 0.01). (4) In summary, Endobutton suspension fixation between metatarsal 1 and 2 for treating hallux valgus is a viable treatment option.

Comparative study of extra vascular occlusion of low abdominal aorta and low abdominal aortic balloon occlusion in the treatment of placenta previa with implantation / 实用医学杂志

Objective To compare the clinical efficacy of extra vascular occlusion of low abdominal aorta and low abdominal aorta balloon occlusion in the treatment of placenta previa with placenta previa.Methods From January 2014 to July 2017,68 implantable placenta previa patients were divided into two groups,elective cesarean section of extra vascular occlusion of low abdominal aorta in 34 cases(group A)and cesarean section on the lower abdominal aorta balloon occlusion in 34 cases(group B),and observation of pregnant women was compared between surgery of two groups. Results Operation time,complications of vascular injury and thrombosis,fetal radiation exposure in group A were significantly lower than that of group B(P<0.05);two groups of patients with sensory dysfunction incidence,cesarean operation time,intraoperative blood loss,blood transfusion rate,the uterus resection rate,hospitalization time had no statistically significant difference postoperatively(P > 0.05). Conclusion Two kinds of operation can safely and effectively reduce the bleeding during the treatment of placenta previa. While group A surgery operation time is short,without intraoperative and postoperative bleeding of the puncture site,without pelvic and lower extremity arterial thrombosis,without X-ray exposure,more safety of the womb and can be popularized in clinic.

The length measurement of adult women abdominal aortic bifurcation to the femoral artery puncture points on interventional methods / 实用放射学杂志

Objective To measure the length between the bifurcation of abdominal aorta to the femoral artery puncture point in adult women.Methods 127 patients were enrolled in the study.Femoral artery puncture using of the roberts uterine catheter (RUC) for the diagnosis and treatment of obstetrics and gynecologic disease was conducted.When the RUC bending vertex code located at the bifurcation above, fingers fixed femoral artery puncture point at the mouth of the catheter's sheath and evacuate the catheter and measure the code to the fixed position.Results In this group, the length of the bifurcation of abdominal aorta to the femoral artery puncture point was 24.38-25.33 cm.There was no significant difference in the length with patient age (P>0.05), but there were statistical significances with the patients height and weight(P<0.05).Conclusion The length of adult women abdominal aortic bifurcation to the femoral artery puncture point has no significant difference with patient age.The individual height and weight are very much significant.The length estimation can be done according to the patient's height and weight for low abdominal aortic catheter,on clinic for avording X-ray irradiation or no X-ray equipment condition.

Biological characteristics of Chinese hamster infected with Babesia / 中国比较医学杂志

Objective To establish a Chinese hamster model of babesia infection, to find the changing pattern of organs and biochemical parameters in Chinese hamster infected with Babesia, and to promote the detection and treatment of babesiosis.Methods Healthy 5-week old Chinese hamsters were infected by intraperitoneal injection of blood containing Babesia.Blood samples were collected at 0, 2, 4, 6, 8, 10, 12, 14, 16, 23, 30, and 37 days after infection from 5 hamsters at each time point.Blood smears were prepared to detect the parasites using Giemsa staining.ELISA assay was employed to test the IL-2 concentration.The blood biochemical indexes were detected using an automatic biochemical analyzer.DNA was extracted from the whole blood and REAL-TIME RCR was performed to determine the reproduction of Babesia.Aftert the animals were sacrificed, the heart, lung, spleen, liver, and kidney were taken to analyze the changes of organ coefficients.Results The highest level of Babesia in the hamsters occurred on day 4 after the Babesia injection, and then showing a decreasing tendency.However, there was a transient increase on the 12th day after infection.The liver and spleen displayed most extensive response to the infection showing hepatomegaly and splenomegaly, but the variation of heart and kidneys coefficients was within the norm.There were prominent changes of blood cells, especially leucocytes, with two peaks at day 10 and 23 after the Babesia infection.The peak changes of blood biochemical indexes occurred at day 12 after infection.The concentration of serum IL-2 reached a peak on the 10th day after infection.Conclusions The Chinese hamsters display typical characteristics of tick-borne diseases such as hepatomegaly and splenomegaly.The immunological system is activated along with the infection and reaches a highest stage in the second week.Afterwards the Babesia can live in the hamster body for a long period of time.The results of this study provide useful information supporting further studies on the detection, treatment and prevention of Babesiosis.

Wiltse paraspinal muscle splitting approach for treatment of L5-S1 spondylolisthesis / 中华全科医师杂志

Forty three patients with L5-S1 spondylolisthesis undergoing surgical treatment from April 2012 to November 2014 were included for analysis,including 20 cases received transforaminal lumbar interbody fusion (TLIF group) and 23 cased received posterior lumbar interbody fusion (PLIF group).The incision length,operative time were shorter and blood loss was less in TLIF group than those in PLIF group [(9.6±0.9) vs.(16.1±1.5) cm,(125.6±13.0) vs.(156.4±11.8) minand (218.7±22.5)ml vs.(326.5 ±20.1) ml,respectively,all P =0.000].There was no statistical difference in the S1 pedicle screw (S1PS) insertion point between two approaches[(29.4 ± 1.9) vs.(28.5 ± 1.0) mm,P =0.069],but the distance from the midline to the lateral edge of the screw (12.9 ±3.6) mm,S1PS angle (23.3 ±2.1) ° and length of S1PS length with the sacral body (40.9 ± 2.6) mm in the TLIF group were better than those in PLIF group (P =0.000).Our results demonstrate that the paraspinal muscle approach for the treatment of L5-S1 spondylolisthesis may be superior with less trauma,better functional recovery and stable screw placement.
