Objective To investigate the clinical efficacy and safety of nebulization treatment for childhood respiratory virus infection with human recombinant interferon α-1b.Methods A randomized,controlled clinical re-search was designed.375 subjects with children respiratory tract virus infection were randomly divided into the treat-ment group(250 cases) and control group(125 cases).In addition to conventional therapy,the treatment group with recombinant human interferon α-1b and the control group with ribavirin were executed by using nebulization treat-ment.Results A total of 357 subjects were statistically included in the trail.Sore throat,cough,wheezes,rale of lung disappearing time and the days of hospitalization of treatment group were significantly different(u=5.83,6.51,6.33, 7.39,5.57,6.62,all P<0.01) compared with the control group;The treatment group in the cure rate and total effec-tive rate was significantly higher(χ2 =7.85,25.71,all P<0.01),and no obvious adverse reactions were reported. Conclusion Nebulization treatment of childhood respiratory virus infection with human recombinant interferon α-1b is safe and effective.The method of operation is simple and thus its application is worth promoting in clinic.

Jingui Yaolue is a part ofTreatise on Cold-Attack and Miscellaneous Diseases. Because of the archaic words, students lost the interest on it. So it became the questions that how to make students interested in learning theJingui Yaolue and to make traditional Chinese medicine(TCM) classical guide clinical treatment. Thus, a try has been made to teach the TCM classic in the clinical practice apprentice setting rather than the classrooms. Here, some experiences about apprentice teaching in clinical practice of Jingui Yaolue were shared.

Objective To evaluate the diagnostic rate and treatment effect of close renal trauma.Methods The clinical data of 129 cases of close renal trauma were analyzed retrospectively. Results Lumbago or bellyache occurred in 109 cases,hematuria 113 cases,coexistent injuries of other organs 81 cases. 129 cases were examined by type B-ultrasonography, 102 cases by CT scan open operation on 17 cases and others were treated non-operatively. 118 cases have been followed up for 3 months to 56 months with normal urine routine and IVU.Conclusions Usually urine inspection and B-ultrasonography were simple,instant reliable and safe. The accurate diagnosis rate was higher with CT scanning,CT scan was helpful in detecting the degree of renal injury and any coexistent injuries,and to estimate the treatment effect. Laparotomy should undertaken for the case of severe injury or with coexistent injuries in rime.

Objective To investigate the effects of alcohol extract of Kunmu decoction on proliferation and apoptosis of rheumatoid arthritis fibroblast-like synoviocytes (RA-FLS). Methods Synovial tissues were obtained from patients with active RA received joint replacement or arthroscopy. The surface antigen and the amount of apoptotic cells were determined by flow cytometry. The inhibitive effect was detected by MTT assay. Results The CD90+surface antigen of synoviocytes was (94.78 ± 0.98)%. The inhibitive effect on the proliferation in all treatment groups were in a time-and dose-dependent manner. The apoptosis rate was increased in a dose-dependent manner among all dosage alcohol extract groups. Conclusion Kunmu decoction might inhibit proliferation and induce apoptosis of RA-FLS.

Objective: To investigate work-related musculoskeletal disorders (WMSDs) of workover workers in an oilfield and explore the influencing factors. Methods: In June 2016, 685 workover workers were selected as working group, and 191 other workers exposed to toxic and harmful operations were selected as control group. Cross sectional investigation was conducted by self-made questionnaire, and the influencing factors of musculoskeletal disorders were analyzed by unconditional multivariate Logistic regression. Results: The total annual prevalence of WMSDs for workover workers was 90.5%, with the highest prevalence of low back pain of 71.5%. The prevalence of WMSDs increased with the increase of service age, and the difference between the drinkers was higher than that of the non drinkers (P<0.05) . Multivariate Logistic regression analysis showed that working age, drinking and the posture of lifting heavy objects were risk factors for WMSDs in workover workers. Conclusion The WMSDs appears to be a serious problem in oilfield workover workers. Corresponding measures should be taken to prevent the risk factors and control the occurrence of diseases effectively.

Objective:To investigate the efficacy of two-way needle suture technique (TNST) in the minimally invasive repair of acute closed Achilles tendon rupture.Methods:From June 2019 to June 2021, 26 patients with acute closed Achilles tendon rupture were treated at Zhengzhou Orthopedic Hospital. They were 20 males and 6 females, with a mean age of 28 (23, 31) years. The rupture end was (4.2±1.3) cm away from the calcaneal insertion, and the interval from injury to operation 4.3 (2.0, 5.0) d. Preoperative MRI examinations revealed in all the patients closed Achilles tendon rupture which was to be repaired by TNST. The operation time, incision length, incidence of complications, ankle dorsiflexion and plantar flexion were recorded. The Arner-Lindholm scoring was used to evaluate the clinical efficacy.Results:The operation time was (20.0±5.0) min and the incision length (2.5±0.4) cm. Postoperatively, all incisions healed by the first stage, with no complications like incision infection, skin edge necrosis, deep vein thrombosis at lower limbs, injury to the sural nerve, or re-rupture of the Achilles tendon. All patients were followed up for (12.0±6.0) months. At the last follow-up, the patients walked normally, their incisions healed well, the continuity of the Achilles tendon was good by palpation, their heel lift was strong, and all their activities were restored to the levels before rupture of the Achilles tendon. The ankle dorsiflexion was 22.6°±3.7° and the plantar flexion 25.3°±3.7°, According to the Arner-Lindholm evaluation, the clinical efficacy was rated as excellent in 25 cases and as good in 1 case, giving an excellent and good rate of 100% (26/26).Conclusion:In the minimally invasive repair of acute closed Achilles tendon rupture, TNST shows the advantages of limited surgical invasion, a low incidence of postoperative complications, and reliable curative effects.

Objective:To evaluate the association between thrombus composition and mechanical recanalization,operation procedure and clinical outcome.Methods:One hundred and ninety-two consecutive stroke patients with large-vessel occlusion treated by mechanical thrombectomy using a stent retriever and (or) aspiration catheter in the Affiliated Huaian No.1 People′s Hospital of Nanjing Medical University between January 2018 and January 2020 were collected. The retrieved thrombi were quantitatively analyzed for red blood cells, white blood cells, platelets, and fibrin. The patients were divided into two groups, a erythrocyte-rich group and a fibrin-rich group based on the predominant composition in the clot. The clinical prognosis, CT value of thrombus, procedure time,number of recanalization maneuvers, and degree of vascular recanalization were compared between the two groups.Results:The retrieved clot from 138 patients with acute ischemic stroke from internal carotid artery occlusion ( n=56), middle cerebral artery occlusion ( n=62), intracranial segment of vertebral artery or basilar artery occlusion( n=20) were histologically analyzed. Erythrocyte-rich clots were present in 59 cases, while fibrin-rich clots were present in 79 cases. Cardioembolic thrombi had higher proportions of fibrin/platelets [77.2%(61/79)], less erythrocytes than noncardioembolic thrombi [45.8%(27/59), χ2=8.115, P=0.004]. Patients with erythrocyte-rich thrombi had a smaller number of recanalization maneuvers [2 (1, 2) vs 3 (2, 4), Z=-7.613, P<0.001], shorter procedure time [45 (30, 60) min vs 80 (60, 90) min, Z=-6.944, P<0.001], higher thrombus CT value [42 (32, 53) vs 36 (31, 41), Z=-2.003, P=0.045], good clinical prognosis (the ratio of modified Rankin Scale score ≤2, 62.7% (37/59) vs 39.2% (31/79), χ2=7.444, P=0.006). There was no significant difference in the location of vascular occlusion between the two groups. Conclusion:For patients whose thrombotic components are mainly red blood cells, the cause of stroke may be non cardiogenic cerebral embolism, the CT value of embolus is relatively high, the embolus is easy to remove, and the clinical prognosis is relatively good.

Objective:To investigate the relations of thrombotic components with cause of stroke, procedure of mechanical thrombectomy, degrees of vascular recanalization and clinical prognoses in patients with large vessel occlusive cerebral infarction.Methods:One hundred and thirty-eight patients with large vessel occlusive cerebral infarction accepted mechanical thrombectomy using stent retriever and/or aspiration catheter in our hospital from January 2018 to January 2020 were chosen. These patients were divided into two groups, a erythrocyte-rich group and a fibrin-rich group, based on the predominant composition in the clots. The baseline clinical data, procedure time, number of recanalization maneuvers, degrees of vascular recanalization and clinical prognoses were compared between the two groups. The relations of infiltration degrees of erythrocytes and fibrin in embolus with procedure time were investigated.Results:The components of thrombus clots were mainly erythrocytes, fibrin, leukocytes, and platelets; erythrocyte-rich clots were presented in 59 patients, and fibrin-rich clots were presented in 79 patients. There was no significant difference in age, gender, preoperative NIHSS scores, proportions of hypertension, proportion of diabetes and proportion of vascular recanalization between the two groups ( P>0.05). As compared with patients from erythrocyterich group, patients in the fibrin-rich group had significantly higher proportion of cardioembolic thrombus (22.8% vs. 77.2%), statically larger number of recanalization maneuvers (2 [1, 2] times vs. 3 [2, 4] times), significantly longer procedure times (45 [30, 60] min vs. 80 [60, 90] min), and significantly lower proportion of patients with modifed Rankin scale (mRS) scores≤2 90 d after surgery (62.7% vs. 39.2%, P<0.05). Procedure time was negatively correlated with erythrocyte infiltration ( r= -0.562, P=0.005) and positively correlated with fibrin infiltration ( r=0.567, P=0.010). Conclusions:Different components of thrombus suggest the etiology of stroke may be different. Thrombus removal is relatively easy in patients with erythrocyte-rich clots, and the clinical prognosis is relatively good.

Objective:To explore the clinical efficacy of periosteum-covered iliac crest autografts for treatment of severe osteochondral lesions of talus （OCLTs）.Methods:A retrospective case series study was used to analyze the clinical data of 26 patients with severe OCLTs treated at Zhejiang Armed Police Corps Hospital from January 2013 to October 2019. There were 21 males and 5 females，aged 17-49 years ［（36.3 ± 10.9）years］. All patients were treated using periosteum-covered iliac crest autografts. The visual analogue scale （VAS），American Orthopedic Foot and Ankle Society （AOFAS） ankle-hindfoot score and ankle joint range of motion （ROM） were assessed before operation，6 months after operation and at the last follow-up （≥ 12 months）. The area of talus injury with MRI at the same level was recorded before operation and at the last follow-up. The healing of talus and joint surface was detected with CT at the last follow-up. The healing of the incision and osteotomy site and complications were observed.Results:All patients were followed for 12 to 22 months［（15.1 ± 3.2）months］. The VAS was （2.4 ± 0.9）points and （1.7 ± 0.6）points at postoperative 6 months and at the last follow-up，significantly lower than the preoperative （5.4 ± 1.2）points （ P < 0.01）. Meanwhile，the VAS at the last follow-up was significantly lower than that at postoperative 6 months （ P < 0.01）. The AOFAS ankle-hindfoot score was （71.7 ± 7.8）points and （87.8 ± 6.2） points at postoperative 6 months and at the last follow-up，significantly lower than the preoperative （66.5 ± 7.5） points （ P < 0.01）. Meanwhile，the AOFAS ankle-hindfoot at the last follow-up was significantly lower than that at postoperative 6 months （ P < 0.01）. The ankle ROM was （58.4 ± 5.5）° and （70.0 ± 4.9）° at postoperative 6 months and at the last follow-up，significantly improved when compared to the preoperative （42.3 ± 8.1）° （ P < 0.01）. Meanwhile，the ankle ROM at the last follow-up was significantly improved when compared to that at postoperative 6 months （ P < 0.01）. The area of talus injury with MRI at the same level was 0.67（0.55，0.89）cm 2 at the last follow-up，significantly improved when compared to preoperative 2.64（1.98，3.68）cm 2 （ P < 0.01）. The transplantation had neither obvious defects nor joint surface steps based on CT findings. All surgical incisions were healed by first intention. There were no complications such as incision infection，skin necrosis，nonunion of osteotomy，malunion or severe ankle joint disorder except that 8 patients had residual local subchondral bone?marrow?edema-like?signal?and 2 patients showed delayed healing of medial malleolus osteotomy. Conclusion:For patients with severe OCLTs，periosteum-covered iliac crest autografts can effectively relieve ankle pain，improve ankle function，and reduce the area of injury.
