Objective To explore the initial effects of the treatment of proximal femoral nail-helical blade (PFNA) in elderly patients with intertrochanteric fracture of the incomplete lateral wall type. Methods A total of 25 patients were enrolled in this study including 8 cases of type A2, 17 cases of type A3 according to AO classification. All patients under-went three-dimensional CT scan. In all patients with type A2 fracture, there were 6 cases with coronal plane fracture on the greater trochanter, and PFNA was used instead of DHS when an iatrogenic fracture occurred in 2 patients. All other patients were treated with closed reduction and fixed with PFNA. Results All patients healed and the average healing time was 11 weeks, one patient fell down once again and the fracture occurred on the shaft, when a long PFNA was used, both of the frac-tures healed 14 weeks after surgery. In all of the 25 patients,1 patient died due to cerebral hemorrhage 13 months after sur-gery;2 patients needed walking aids due to the presence of osteoarthritis of the knee and calf muscular venous thrombosis was diagnosed in 3 cases. No complications were found in the other patients, such as infection, nonunion and fixation failure. According to the Harris hip score system, there were 14 cases of“excellent”,8 cases of“good”,2 cases of“fair”and1 pa-tient of“poor”.Conclusion The PFNA treatment can provide a good fixation for intertrochanteric fractures of incomplete lateral wall type, which allow patients to do exercise early and achieve an excellent initial outcome.

The molecularly imprinted separating medium with halloysite nanotubes as carrier, which were environmentally friendly natural silica substrate nano-materials, aspirin as template molecule and acrylamide as functional monomer was synthesized using reversible addition fragmentation chain transfer polymerization. The template molecule and monomer were bound to stable composite at 1: 2 using the method of ultraviolet spectroscopy combined with Lamber-Beer theory at molecular level. The morphology and adsorption capacity of imprinted material was studied with Fourier transform infrared spectrometer ( FT-IR ) , transmission electron microscope ( TEM) , static adsorption and selective adsorption. The experimental results showed that a good uniformity of imprinted layer with the thickness of 38 nm was coated steadily on the halloysite nanotubes surface. Compared with the conventional surface imprinted material and the material with silica gel as carrier, our molecularly imprinted material had the characteristics of high adsorption capacity and favorable imprinted effect. Its imprinted factor achieved to 3. 5. The molecularly imprinted material was applied for mimetic intestinal juice diffusion experiment. The experimental results indicated that the imprinted material release the aspirin for 12 h, which was 2 times for non imprinted material for only 6 h, demonstrating excellent drug release result, which provided basic data for potential applications of drug carrier.

Objective To evaluate the effect of percutaneous transforaminal endoscopic discectomy (PTED) using tar?get puncture and 2-stage procedures in treating lumbar disc hernia. Methods Patients present in our clinic from January 2014 to June 2014 with lumbar disc hernia who were treated with PTED were collected (n=36). Lower back and leg pain were evaluated by visual analog scale (VAS) while clinic outcome were assessed by Oswestry disability index (ODI) and modified Macnab criteria. Results All surgeries were carried out successfully. On average, operation time was(125±31)min, blood loss was(8.5±2.9)mL in each operation. The average length in hospital stay was(7.6±3.5)day. Compared with the preoper?ative VAS scores,the postoperative and last follow-up scores for lower back and leg pain decreased significantly (P<0.01). The ODI of pre-operation and last follow-up were (18.90 ± 7.78)%and (73.30 ± 18.21)%respectively with statistic differ?ence. As to the modified Macnab criteria,theexcellent and goodratio was 94.4%. One case present hyperalgesia in L4 der?matome which recovered through conservative treatment. No complications such as permanent nerve root injury ,cerebrospi?nal fluid leakage,or infection were found during or after operations. All patients are in stable conditions during follow-up pe?riod without recurrence. Conclusion PTED using target puncture and 2-stage procedures is an effective method with mini?mal trauma, less bleeding, quick recovery, high security, short hospitalization time. what′s more, it can remove protruded disc and broken nucleus from the intervertebral space. It ensure efficacy and avoid recurrence.

Objective To investigate short?term clinical outcomes of XLIF through small incision approach combined with percutaneous pedicle screw fixation for degenerative lumbar scoliosis. Methods From December 2011 to June 2013, 15 pa?tients with degenerative lumbar scoliosis were treated by XLIF combined with percutaneous pedicle screw fixation (XLIF group). There were 6 males and 9 females, with an average age of 68.27±5.70 (ranging from 58 to 75) years old and Cobb angle of scoliosis 22.20°±6.66° (ranging from 14° to 35°). Meanwhile, 23 patients were treated with posterior lumber inter?body fusion (PLIF) com?bined with pedicle screw fixation (PLIF group). There were 9 males and 14 females, with an average age of 63.26 ± 6.03 (ranging from 49 to 73) years old and Cobb angle of scoliosis 23.17°±6.95° (ranging from 13° to 36°). The efficacy was assessed through cor?rection rate of Cobb angle, VAS and lumbar JOA score at the time of the latest follow?up. Results The operation time was 224.35 ± 51.53 min in the PLIF group and 197.47 ± 31.84 min in the XLIF group. No significant differences were found, but there was significantly difference in the intraoperative blood loss (PLIF group: 576.52 ± 227.89 ml, XLIF group: 181.33 ± 47.37 ml, t=-8.054, P<0.001). No patient accepted blood transfusion in the XLIF group, but in the PLIF group, 11 patients accepted blood transfusion. The Cobb angle, VAS and JOA score in two groups were improved compared with the preoperative. 38 patients were followed up for 12 to 32 months, with an average of 23 months. The correction rate of Cobb angle, VAS and JOA scores were 56.90%±11.51%, 87.97%±12.07%, 84.00%±5.59%in the XLIF group, and 62.88%±8.28%, 83.68%±12.33%, 84.79%±6.76%in the PLIF group. No significant differences were found between the two groups (P>0.05). Conclusion Treatment of degenerative lumbar scoliosis with XLIF through small incision approach combined with percutaneous pedicle screw fixation is a kind of safe and effective minimally invasive spine surgery with small trauma and less bleeding, and the recent surgery efficacy was close to PILF.

Objective To explore the value of 3.0T diffusion weighted imaging (DWI)in predicating and evaluating the efficacy of concurrent chemoraidotherapy (CCRT)in esophageal car-cinoma.Methods A total of 46 patients with esophageal carcinoma were divided into group A (with complete disappearance of high signal intensity)and group B (with incomplete disappearance of high signal intensity)based on the complete disappearance of high signal intensity of esophageal lesion and metastatic lymph node after 1 to 3 months of CCRT so as to measure the changes of esophageal lesion length and apparent diffusion coefficient (ADC)value of normal and lesion tissues, and were divided into T1-3 group (without affection)and T4 group (with affection)to analyze the differentiation of ADC values in both groups,according to the affection of esophageal lesion to sur-rounding tissues and organs distinguished by DWI.Additionally,all patients were divided into N0 group (without metastasis)and N1 group (with metastasis)on the basis of metastasis of medi-astinum lymph node determined by DWI,so as to analyze the differentiation of ADC values in both groups.Results After CCRT,esophageal lesion length decreased evidently than treatment before and the difference was statistically significant.ADC values in groups A and B were obviously lower than that in the esophageal normal tissues before and after treatment,while ADC value increased markedly in all groups after treatment compared with the treatment before,and ADC value was ap-parently higher in group A than that in group B.However,there was no significant difference be-tween T1-3 and T4 groups.Moreover,N0 group was obviously higher than N1 group in ADC value,and the difference was significant.Conclusion CCRT can obviously shorten esophageal lesion and increase ADC value in malignant lesion tissues of tumor,which suggested that ADC value can re-flect the internal metabolism changes and concurrent chemoraidotherapy of tumor earlier and more accurately.

Objective:To observe the protective effect of deproteinized extract of calf blood (DECB)on the ethanol-induced liver injury of the mice,and to preliminaryly discuss its mechanism. Methods:Sixty healthy ICR mice were divided into control group,model group,positive drug group,low,medium and high doses of DECB groups (n=10).By intragastric administration,the mice in control group were given 20 mL·kg-1 saline solution, the mice in low,medium and high doses of DECB groups were administrated with 0.125,0.250,0.500 g·kg -1 DECB,and the mice in positive drug group were administrated with 0.63 g·kg -1 Hugan Tablets;once a day for 30 d. 1 h after the last administration,except control group,the mice in other groups were administrated with one-time grant of 50% ethanol 14 mL·kg -1 ,and fasted for 16 h to establish the models of acute alcohol liver injury.The endurance alcohol time and drunk time of the mice were determined,the activities of aspartate aminotransferase (ALT)and alanine transaminase (AST)activity in serum of the mice were detected,the levels of triglyceride (TG),glutathione (GSH)and malonic dialdehyde (MDA)in liver tissue were determined,and the pathological changes of liver tissue were detected.Results:Compared with model group,the drunk symptoms of the mice in different doses of DECB groups were obviously reduced,the endurance time of the mice in high dose of DECB group and positive drug group was prolonged (P <0.05),and the drinking time was shortened (P <0.05);the ALT and AST activities in serum in mediun and high doses of DECB groups were significantly lower than those in model group (P <0.05).Compared with model group,the MDA and TG levels in liver tissue of the mice in medium and high doses of DECB groups and positive drug group were obviously reduced,and the GSH levels were increased (P <0.05);compared with model group,the pathological damages of liver tissue of the mice in high dose of DECB group caused by ethanol were significantly reduced.Conclusion:DECB can improve ethanol-induced liver injury which may be related to the inhibition of hepatic oxidative stress response.

Objective:To investigate the clinical effect of percutaneous curved kyphoplasty in the treatment of old osteoporotic vertebral body with endplate fracture.Methods:Clinical data of 58 patients suffering from old osteoporotic vertebral bodies with endplate fractures from January 2018 to January 2020 were analyzed retrospectively. All patients had a single vertebral body fracture and were treated with bilateral injection of bone cement with percutaneous kyphoplasty (PKP). According to the shape of the puncture device, the patients were divided into a curved needle group and a ordinary group. There were 28 cases in the curved needle group, including 7 males and 21 females, aged 60-84 years old, with an average age of 71.8±7.8 years. The distribution of vertebral bodies with fractures: T 11 3 cases, T 12 5 cases, L 1 6 cases, L 2 5 cases, L 3 3 cases, L 4 4 cases, and L 5 2 cases. In the ordinary group, there were 30 cases, 8 males and 22 females, with an average age of 73.2±8.4 years (range, 61-88 years). The vertebral body distribution of fracture: T 11 3 cases, T 12 5 cases, L 1 7 cases, L 2 4 cases, L 3 4 cases, L 4 5 cases, and L 5 2 cases. The surgery time, amount of bone cement injection, and bone cement leakage rate were compared between the two groups, as well as the visual analogue scale (VAS) and Oswestry disability index (ODI) at 1 week, 6 months, and 1 year after surgery. Preoperative and postoperative vertebral midpoint height and kyphosis Cobb angle were measured. Results:All patients were followed up for 12-24 months, with an average of 14.7±2.9 months. The bone cement leakage rate in curved needle group (18%, 5/28) was lower than that in ordinary group (23%, 7/30), but there was no significant statistical difference (χ 2=0.27, P=0.607). The amount of bone cement injection and surgery time in curved needle group (5.0±0.5 ml, 55.2±6.9 min) were significantly higher than those in ordinary group (3.4±0.6 ml, 42.9±3.6 min, P<0.05) . The scores of VAS (2.3±1.0, 2.6±1.5) and ODI (27.5%±9.7%, 28.7%±11.3%) in curved needle group were lower than those in ordinary group (2.7±1.0, 4.5±1.1 and 31.8%±10.5%, 43.1%±13.4%) at 6 months after surgery and at the last follow-up after surgery. In the curved needle group, the Cobb angle was 25.5°±3.5° preoperatively, 18.4°±1.6° postoperatively, and 20.5°±4.9°at the last follow-up. The height of the vertebral body was 14.2±1.9 mm before surgery, 21.5±2.2 mm after surgery, and 20.1±3.6 mm at the last follow-up. Compared with the preoperative results, the kyphosis Cobb angle decreased and the height of the fractured vertebral body increased at the last follow-up, and the differences were statistically significant ( P<0.05). In the ordinary group, the Cobb angle was 24.4°±3.6° preoperatively, 23.1°±4.0° postoperatively, and 27.8°±2.9° at the last follow-up. The height of the vertebral body was 14.5±1.8 mm before surgery, 15.4±2.0 mm after surgery, and 12.7±1.0 mm at the last follow-up. At the last follow-up, the kyphosis Cobb angle increased and the height of the fractured vertebral body decreased compared with preoperative and postoperative 1 week, and the differences were statistically significant ( P<0.05). At 1 week after surgery, 6 months after surgery and the last follow-up, the Cobb angle of curved needle group was lower than that of ordinary group ( P<0.05), the height of vertebral body was higher than that of ordinary group ( P<0.05). Conclusion:Flexible application of percutaneous curved kyphoplasty in the treatment of old osteoporotic vertebral body with endplate fractures can effectively increase the riveting force of bone cement in the vertebral body, restore the height of endplate, and reduce the occurrence of kyphosis and chronic low back pain.
