Objective:To explore the clinical effect of combining kinesio taping with filtered infrared-A irradiation in the treatment of scapulohumeral periarthritis.Methods:Eighty-six patients with scapulohumeral periarthritis were randomly divided into a control group ( n=43) and an observation group ( n=43). Both groups received 20 minutes of irradiation with water-filtered infrared-A per day for 14 days, while the observation group was also given kinesio taping after the irradiation on 6 days of each week for the two weeks. Before and after the 2 weeks of treatment, both groups were evaluated for pain, their active and passive range of motion (AROM and PROM) of the shoulder, as well as the range of motion (ROM) of the shoulder joint, and their Constant-Murley score (CMS). The subjects also evaluated the functioning of their own shoulders using a visual analogue scale (VAS). Results:After the treatment, the average VAS scores of both groups were significantly higher than before the treatment, but the observation group′s average was significantly higher than that of the control group. There was significant improvement in the average AROM and PROM in both groups, but in the observation group the average AROM in anteflexion, rear protraction, abduction and extorsion and the average PROM in anteflexion and abduction were significantly better than the control group′s averages. The average total CMS scores of both groups had also improved significantly, but with significantly greater improvement in the observation group leading to a significant difference between the two groups after the intervention.Conclusions:Supplementing water-filtered infrared-A irradiation with kinesio taping is very effective in relieving pain, as well as improving ROM and life quality for persons with scapulohumeral periarthritis.

ObjectiveTo investigate application of the anterior cervical pedicle screw in the lower cervical spine.MethodsTwenty disarticulated human vertebrae(C3-C7) were evaluated with computed tomography for pedicle morphometry Parameters included vertebral body height,vertebral body depth,vertebral body width,outer pedicle width,outer pedicle height,pedicle axis length,transverse section angle,sagittal section angle,transverse intersection point distance and sagittal intersection point distance.On the basis of these data,the screw channel was determined and the screws were inserted in the specimen.Five patients underwent surgical reconstruction using anterior pedicle screw fixation.After surgery,physical examination and roentgenograms and CT scans were performed in all patients.ResultsThe transverse section angle increased from C3(45.7°±4.0°) to C5(52.1°±5.9° ),but decreased from C6(47.8°±6.7°) to C7(44.4°± 8.3°).The sagittal section angle gradually increased from C3 (93.4°±7.2°) to C6( 112.1°±6.2°) but decreased a little to C7(102.7°±8.5°).The distances in transverse section was about 1.97-3.98 mm and in sagittal section was 3.4-7.5 mm.Anterior pedicle screws were inserted successfully in all specimens without critical pedicle wall perforations.Patients were permitted to ambulate the next day after surgery with a cervical collar.Postoperative neurological improvement was observed in all cases.Postoperative radiographic evaluation confirmed proper insertion of anterior pedicle screws without pedicle perforaton.The average follow-up time was 10.6 months.No anterior pedicle screw breakage and loosening was observed.ConclusionThe entry point in anterior pedicle screw should located in 5mm to upper endplate and near anterior median line.The transverse section angle should be 45.7°-52.1°and the sagittal section angle should be 93.4°-112.1°.The lengths of the screw should be about 32 mm.

Objective To identify the feasibility and the anatomical parameters of posterior transarticular pedicle screw fixation in the thoracic spine, provide a reference for clinical applications. Methods Twenty human cadaveric thoracic spine segments were dissected posteriorly and anteriorly, with care taken to expose the laminas and pedicles. The entrance point of transarticular pedicle screws was located in the 7 mm away from the above at the inferior margin of the lamina and the inside at the exterior margin, respectively. Posterior transarticular pedicle screws implantation was performed under direct visualization into T1,2,T5,6 and T9,10 Under direct abservation, the feasibility of posterior transarticular pedicle screw fixation was assessed. Then a CT was done. On the morphologic CT scan, the angle and length of the transarticular pedicle crew trajectory were measured. Results The thoracic transarticular pedicle screw trajectory were caudal tilting in the sagittal plane and lateral tilting in the axial plane with successful placement. Screws were placed across the facet joint, and from the inferior articular process of upper thoracic vertebra into the pedicle of lower thoracic vertebra. There was little difference between different number of thoracic vertebrae of the angle, but without significance. The average angles of the screws were 41.4°+3.2°caudal tilting in the sagittal plane and 2.1°±0.7° lateral tilting in the axial plane. The average trajectory lengths were (40.6±4.9)mm, and the lengths increased gradually from upper thoracic vertebra to middle and lower. There were significant differences statistically among T1,2, T5,6 and T9.10 (F=74.09, P＜0.01 ). Conclusion Posterior transarticular pedicle screw fixation is feasible, and there are some directions for implantating the screws. Transarticular pedicle fixation in the thoracic spine affords an alternative to standard pedicle screw placement for thoracic stabilization.

Objective To analyze the feasibility and effect of combining intramedullary nails and plates in the treatment of ipsilateral unicondylar tibial plateau fractures with non.contiguous tibial shaft fractures.Methods From May 2003 to November 2005,21 patients with ipsilateral unicondylar tibial plateau fracture and non-contiguous tibial shaft fracture were treated with combining intramedullary nails and plates,including 15 males and 6 females,with the mean age of 34 years (range,20-55 years).The tibial plateau fractures were classified according to Schatzker et al.; 4 cases were type Ⅰ,11 cases type Ⅱ,6 cases type Ⅲ and 1 case type Ⅵ.Middle third tibial shaft fractures were in 13 patients,and distal third tibial shaft fractures were in 8 patients.Once the reduction was obtained,we first fixed tibial plateau with plate and then tibial shaft with medullary nail in 19 cases; in 2 cases,we first fixed the tibial shaft with medullary nail and then tibial plateau with plate.Results 1All patients were followed up for 0.9 to 4 years (average,2.2 years).Bone union was obtained in all patients.The tibial plateau fractures united after an average of 12 weeks,and the tibial shaft fractures united after an average of 29 weeks.Delayed union of the tibial shaft fracture occurred in 3 patients,and the fracture healed finally by removing the proximal locking.Tibial plateau malunion occurred in one patient due to malreduction.According to HSS scores,excellent result was obtained in 17 patients (80.95％),good in 3 patients (14.29％),fair in 1 patient (4.76％).Conclusion With careful attention to some techniques,ipsilateral unicondylar tibial plateau fractures with non-contiguous tibial shaft fractures can be treated successfully by combining medullary nail and plate.

Objective:To investigate the feasibility and safety of laparoscopic liver tumor resection in children.Methods:The clinical data of 6 children undergoing laparoscopic liver tumor resection from June 2018 to March 2020 in the Affiliated Tumor Hospital, Zhengzhou University were retrospectively analyzed.Results:There were 4 males and 2 females among the 6 cases, with the average age of (7±2)years.All the children were admitted to the hospital with a liver occupying examination due to physical discomfort.Preoperative diagnosis: 3 cases of hepatoblastoma, 1 case of primary liver cancer, 1 case of hepatic adenoma and 1 case of hepatic nodular hyperplasia.All the children successfully completed laparoscopic liver tumor resection without conversion to open surgery.Among them, 3 children obtained left hemihepatectomy, 1 child underwent hepatic left lobectomy, 1 child was given VI hepatectomy, and 1 child accepted hepatic caudate lobectomy.The operation time was(90±9)min, and the average intraoperative blood loss was (83±26) mL.All children had no blood transfusion during or after operation.There were no bleeding, bile leakage, infection and liver failure after operation.All children had no gastric tube before surgery and the fluid diet was given on the first day after operation, and the postoperative median hospital stay was 4(3-5) days.The pathology were consis-tent with the preoperative diagnosis, and the resections were all radical operation resections.The follow-up period was from 2 to 23 months, and all the children recovered well and no recurrence was observed.Conclusions:Laparoscopic liver tumor resection in children is safe and feasible, which can minimize trauma, reduce intraoperative bleeding and shorten the hospital stay without increasing the incidence of postoperative complications.Laparoscopic liver tumor resection in children has certain advantages.

Hepatocellular carcinoma (HCC) is one of the most common malignant tumors, and its features of insidious onset, rapid development, and high recurrence bring great challenges to the long-term survival of HCC patients. Molecular-targeted drugs and immune checkpoint inhibitors have become the research hotspots in the treatment of HCC, and a large number of clinical trials have found that combined therapy has achieved a good clinical effect. This article mainly introduces the application of combined therapy with molecular-targeted drugs and immune checkpoint inhibitors and other combined therapies in HCC and points out that combined therapy related to systemic therapy or local therapy has become the latest research hotspot in HCC treatment.

This study shows the case of a patient with peroneus brevis tendon rupture in ankle fracture. The patient com-plained of swelling, pain and activity limitation in her right ankle caused by sprain. She was diagnosed with ankle fracture, supina-tion-adduction (Lauge-Hansen typing) by medical history, physical examination and imaging. The peroneus brevis tendon was not-ed complete ruptured when suturing the incision after ORIF, which was then repaired by "8" shaped suture. Based on literature re-view, the injury mechanism of the case may be because of overload inversion force toward to lateral inferior from the fracture of fib-ula on the peroneus brevis tendon. Additional attention should be paid to patients who suffered from an supination-adduction ankle fracture for whether peroneus brevis tendon tears before and during surgery.

Using mutation PCR, we cloned the target gene containing 421-480nt (141-160aa) and 598-639nt (200-213aa) of VP1 gene of foot and mouth disease virus (FMDV) into the deleted region (508-532aa) of Nsp2 gene of a highly pathogenic porcine reproductive and respiratory syndrome virus derived vaccine strain (HuN4-F112) that was used as vector. The recombinant cDNA was in vitro transcribed followed by transfection of BHK-21 cells for 36 h. Then, the supernatant of the cell culture was continuously seeded to monolayer of MARC-145 cells for recovery of the recombinant virus. CPE was obviously visible after a couple of passages in the seeded MARC-145, and the rescued virus (designated as rPRRSV-F112-O/VP1ep) was identified by Mlu I digestion, sequencing and immunofluorescence assay. Meanwhile, expression of inserted FMDV epitopes was also detected by indirect immunofluorescence assay with polyclonal antibodies against VP1 protein of FMDV. The analysis of biological characteristics shows that the titer of the rescued recombinant PRRSV (TCID50 = -log10(-6.75)/0.1 mL) was similar to its direct parental virus rHuN4-F112-delta508-532, but higher than rHuN4-F112.

Objective To analysis the short-term quality of life and clinical outcome of early enteral immunonutrition(EIN)used after operation in patients with totally endoscopic esophagectomy.Methods This randomized controlled trial enrolled 110 patients receiving totally endoscopic esophagectomy in department of thoracic surgery of the fourth hospital of Hebei medical university between May 2015 and November 2016.The patients were randomly divided into enteral immunonutrition group (EIN group,n =56) and parenteral nutrition group (PN group,n=54).The scale scores of quality of life,the time of first postoperative anal exhaust,the time of removal of drainage tube,the number of postoperative infections and the length of hospitalization were compared between the two groups before operation and after operation.Results (1) There were no significant differences in age,gender,education,marital status,tumor location,clinical stage,intraoperative bleeding between the two groups (P＞0.05).(2) There were no significant differences in the quality of life before operation (P＞0.05);All functional scale scores of EIN group were significantly higher than PN group (P＜0.05),while the symptom scale score were significantly lower than PN group(P＜0.05).(3) There were significant differences in the time of first postoperative anal exhaust,the time of removal of drainage tube,the number of postoperative pneumonia compliCations and the length ofhospitalization in the two groups (P＜ 0.05).There was no significant difference in the incidence of anastomotic fistula between the two groups(x2=0.621,P=0.431 4) The scale scores of quality of life (the overall health status as the representative) had a negatively linear relationship with the clinical outcome(P =0.000),the absolute value of correlation coefficient in EIN group was higher than that in PN group.The higher score of the quality of life,the shorter time of the postoperative anal exhaust,removal of drainage tube and the length of hospitalization.Conclusion Enteral immunonutrition can improve the quality of life,improve the prognosis and promote the rapid recovery of patients with totally endoscopic esophagectomy.

Hepatocellular carcinoma (HCC) is mostly treated by surgery combined with interventional therapy, chemotherapy, radiotherapy and local treatment. However, it often relapses after the operation. And the prognosis of advanced patients is poor, and the effective rate of chemotherapy and molecular targeted therapy is low. Recent studies indicated that the occurrence and progress of HCC are closely related to the immune function of the body. Immunotherapy, as a new type of tumor therapy, has drawn much attention. By improving the immunogenicity of tumor cells and the killing sensitivity of effector cells, it stimulates the immune function of the body, prolongs the progression-free survival time and the overall survival time of patients, and becomes an integral part of the comprehensive treatment of liver cancer. This article reviewd the progress in immunotherapy of HCC in the recent years.
