ObjectiveTo introduce the design of the instrument for percutaneous posterolateral foraminoplasty and analyze long-term outcomes of percutaneous foraminoplasty and transforaminal endoscopic discectomy in the treatment of non-contained lumbar disc herniation.MethodsFifty-six patients with noncontained lumbar disc herniation confirmed by symptom,physical sign and concordant imaging underwent percutaneous foraminoplasty and transforaminal endoscopic discectomy,including 7 cases of L3-4,30 of L4-5 and 19 of L5S1.The visual analogue scales(VAS) of pre- and post-operative low back pain and sciatica were compared,and the Macnab scores were also evaluated.ResultsAll of the procedures were performed successfully,with mean operation time of 60 min(range,40-120 min),and a mean blood loss of 30 ml (range,20-50 ml).The follow-up time was more than 36 months.Postoperative VAS of low back pain and sciatica were significantly decreased compared with preoperative VAS (P＜0.01).There were 44 cases of excellent,10of good,and 2 of fair according to Macnab score system,with total successful rate (excellent and good) up to 96.4％.Only 5 cases with L5S1 disc herniation were found complicated with sun-burn syndrome,which were relieved by pulsed electro-stimulant therapy for 1 week.ConclusionPercutaneous foraminoplasty and transforaminal endoscopic discectomy is an effective and safe minimally invasive treatment alternative for non-contained lumbar disc herniation.

In this study the relation between the extent and type of disc protrusion and the clinical severity of symptoms of low back pain was observed. Our series consisted of 300 consecutive cases of lumbar disc protrusion,with their diagnosis confirmed by intraoperative observation. Preoperative pain severity was assessed using a back pain scale that combined the symptoms of back pain and sciatica. Intraoperaative pathological findings of disc were documented and comparesd with preoperative symptoms and signs. The pathological changes of disc were classified as following four subtypes: bulging disc (85 cases), protruding disc (104 cases), extruded disc (72 cases) and sequestered disc (39 cases). Our results suggest that severity of pain in patients with herniated lumbar disc is related to position of herniation rather than magnitude and exent of herniation. Inflammed intraspinal tissues are significantly associated with low back pain and sciatica.

Objective To retrospectively analyze the results of unilater al external fixators in the treatment of the distal third fractures of humeral s hafts. Methods From October 1997 to October 2002, 33 patients from 15y-70y (ave rage 31y) with the distal third fractures of humeral shafts were treated with un ilateral external fixators. They included 3 transverses fractures, 1 oblique fra cture, 9 spiral fractures and 20 comminuted fractures. 15 cases were treated wit h open reduction and fixation with external fixators and limited internal fixati on, 10 cases were treated with open reduction and fixation with external fixator s, and 9 cases were treated with closed reduction and fixation with external fix ators. 9 cases with radial nerve injury undewent nerve exploration. External fix ators were removed after bone healing. Duration of follow-up was 8 to 24 m (ave rage 18 m). Results The time of bone healing was 11 to 22 w (average 14 w). At t he latest follow-up, the function of injured radial nerves in 9 preoperative ca ses and 2 postoperative cases and the motion function of elbow were restored to normal. There were only 7 cases of superficial pin site infection which were cur ed with oral antibiotics and pin site care with mild disinfectants. Conclusion U nilateral external fixators can play special roles and have good results in the treatment of the distal third fractures of humeral shafts, combined with open re duction and limited internal fixation.

Objective To summarize the diagnosis and treatment of congenital pulmonary airway malformation in children.Methods The clinical data of 68 children with congenital pulmonary airway malformations from June 2014 to June 2017 were analyzed retrospectively,including 39 males and 29 females with mean age(1.1 ±:0.5) years old(from 2 months 12 days to 15 years),7 cases of pulmonary cyst resection in 68 cases,3 cases with lung segment resection,1 cases with lingulectomy,57 cases with lobectomy.Results 68 cases were cured and discharged without death.Postoperative short-term complications included subcutaneous emphysema in 5 cases,pleural effusion in 2 cases,pneumothorax in 2 cases.All cases were followed up well between 3 months and 1 year.Conclusion The diagnosis of congenital pulmonary airway malformation in children mainly depends on imaging examination.Because it is easy to repeat infection,and can not rule out malignant transformation,early diagnosis and early treatment should be done.Surgical resection is the only way to treat the disease.

OBJECTIVETo investigate the epidemiological characteristics of lower back pain of truck drivers in plateau areas with an analysis of the causes and evaluated the effects of the protective measures.

METHODSThe self-reported lower back symptom was investigated by questionnaire in 1,132 male drivers in plateau areas. Vibration of the driver lumbar back was measured real time with or without wearing corset. Study the effect of the special corset for drivers and the massage on back by self-control design of big sample intervention experiments.

RESULTSThe prevalence of lower back pain of drivers in plateau areas was 86.1%. High level of its prevalence is due to many factors. Special corset for drivers and massage on back by themselves can reduce the degree of the pain.

CONCLUSIONDriving in plateau areas is a special occupational work with high level of prevalence of lower back pain which can be prevented.

Objective To explore the clinical effect of surgery-first approach (SFA) for correcting adult skeletal class Ⅲ malocclusion deformity patients.Methods A total of 28 adult patients diagnosed with skeletal class Ⅲ malocclusion were treated.Bilateral sagittal split ramus osteotomy (BSSRO) and geniplasty were performed without presurgical orthodontics treatment;postoperative orthodontics treatment was carried out after a healing period of 2-4 weeks.Lateral cephalometric radiographs were taken preoperatively (T1),within a week posoperatively (T2) and six months posoperatively (T3);cephalometric measurements were carried out by the software.Results All the patients were satisfied with the effect,no complications occured.The mean postoperative orthodontics treatment duration was 13.2 months.The mean setback of mandible at Po and B point was (7.74 ± 3.93) mm (P＜0.01) and (8.13±3.84) mm (P＜0.01),and superior movement lengths were (2.73±1.83) mm and (2.76±1.67) mm,respectively.Compared to T2,Po and B point moved forwardly with (2.36±1.23) mm and (2.66±1.65) mm,and inferior movment were (2.16±1.37) mm and (1.21±0.87) mm,respectively.The mean decrease of SNB and GA was (3.74± 1.61)° (P＜ 0.01),(3.41± 1.87)° (P＜0.01),respectively.During postoperative period,both of them increased,although these were no statistical differences.Conclusions SFA combined postoperative orthodontics therapy is feasible for the correction of adult skeletal class Ⅲ malocclusion,which has shorter treatment duration than traditional joint orthognathic-orthodontic.With the advantages of earlier improvements in patient's facial aesthetics and dental function,the reduction in difficulty and treatment duration of orthodontic management,and increasing patient acceptance.

Objective: To investigate the effects of ovarian cancer cells on the glycolysis metabolism and functions of peripheral CD4 + T cells. Methods: We established a coculture system of human CD4 + T cells with ovarian cancer cell SKOV3, and the mRNA expression levels of 8 glycolysis-related genes (mTORC1, HIF1α, GLUT1, GPI, ENO1, PKM2, LDHα and PDK1) in cocultured CD4 + T cells were determined by real-time fluorescence quantitative PCR. The levels of glucose uptake and glycolysis were detected by colorimetry. The proportion of CD4 + CD25 + Foxp3 + T cells was tested by flow cytometry. The proliferation levels of CD4 + T cells were measured by tritium incorporation method. The expression levels of 8 glycolysis-related genes in peripheral CD4 + T cells were determined by real-time fluorescence quantitative PCR in 10 ovarian cancer (OC) patients, 10 benign ovarian tumor (BOT) patients and 10 healthy control (HC). Results: Results: Compared with the CD4 + T cells in single culture without SKOV3, the expression levels of 8 glycolysis-related genes in CD4 + T cells cocultured with SKOV3 were elevated (all P＜0.01). The levels of glucose uptake and glycolysis were increased (P＜0.05). The proportion of CD4 + CD25 + Foxp3 + T cells was up-regulated (P＜0.05) and the proliferation levels of CD4 + T cells were decreased (P＜0.05). Moreover, the mRNA expression levels of all the glycolysis-related genes were increased (all P＜0.05) in the peripheral CD4 + T cells of OC patients compared with BOT patients and HC. Conclusion Ovarian cancer cells could promote the glycolysis metabolism of CD4 + T cells, which may be relevant to its differentiation and functions.

Meigs' syndrome (MS), a rare complication of benign ovarian tumors, is easily misdiagnosed as ovarian cancer (OC). We retrospectively reviewed the clinical laboratory data of patients diagnosed with MS from 2009 to 2018. Serum carbohydrate antigen 125 and HE4 levels were higher in the MS group than in the ovarian thecoma-fibroma (OTF) and healthy control groups (all P < 0.05). However, the serum HE4 levels were lower in the MS group than in the OC group (P < 0.001). A routine blood test showed that the absolute counts and percentages of lymphocytes were significantly lower in the MS group than in the OTF and control groups (all P < 0.05). However, these variables were higher in the MS group than in the OC group (both P < 0.05). The neutrophil-to-lymphocyte ratio (NLR) was also significantly lower, whereas the lymphocyte-to-monocyte ratio was higher in the MS group than in the OC group (both P < 0.05). The NLR, platelet-to-lymphocyte ratio, and systemic immune index were significantly higher in the MS group than in the OTF and control groups (all P < 0.05). The hypoxia-inducible factor-1 mRNA levels were also significantly higher, whereas the glucose transporter 1, lactate dehydrogenase, and enolase 1 mRNA levels were lower in peripheral CD4
