Objective To evaluate the effect of ultrasound-guided selective brachial plexus block on postoperative muscle strength in the block area of patients after wrist surgery.Methods Sixty patients who underwent wrist surgery,33 males and 27 females,aged 18-64 years,BMI 21-28 kg/m2,ASA physi-cal status Ⅰ or Ⅱ,were randomly divided into two groups by random number table method:ultrasound guided selective brachial plexus block in the middle of the forearm group(group A)and ultrasound guided axillary brachial plexus block group(group B),30 patients in each group.In group A,the ulnar nerve,and/or median nerve,and/or radial nerve were selectively blocked in the middle of the forearm according to the location of the surgical incision,and 0.4％ropivacaine was injected into each nerve with 5 ml.Patients in group B received conventional axillary brachial plexus block under ultrasound guidance and injected 30 ml of 0.4％ropivacaine.In the both two groups,dexmedetomidine 0.8 μg/kg was injected for 10 minutes be-fore nerve block,and was changed to 0.4 μg·kg-1·h-1 until the end of operation,and then patients were transferred to the recovery room for observation 30 minutes and then returned to the ward.Muscle strength 2,4,8,12,24,48 hours after operation and recovery time to grade 5 were recorded.VAS pain scores at rest and exercise 2,4,8,12,24,and 48 hours after surgery and tourniquet tolerance scores were recorded.Satisfaction score,nerve block operation time,anesthesia onset time,duration of analgesia,number of addi-tional postoperative analgesics,occurrence of postoperative remedial analgesia,and length of hospital stay were recorded.Complications such as hematoma,nerve injury and infection were recorded.Results Com-pared with group B,the muscle strength score of patients in group A 2,4,8 and 12 hours after surgery was significantly higher(P＜0.05),the time of muscle strength recovery to level 5 in group A was significantly shorter(P＜0.05).Compared with group B,the satisfaction score in group A was better(P＜0.05),the duration of nerve block operation and hospitalization in group A was shorter(P＜0.05),the intraoperative tourniquet tolerance score of in group A was worse(P＜0.05),and both groups were tolerated.There were no significant differences in VAS pain scores at rest and exercise,the onset time of anesthesia,duration of analgesia,number of postoperative analgesia remedies between the two groups.There were no complications such as hematoma,nerve injury and infection in the two groups.Conclusion Ultrasound-guided selective brachial plexus block has little effect on the motor function of upper arm and forearm,and muscle strength recovers quickly after operation,can be safely and effectively adopted in short wrist surgery.

Objective To observe the effect of intelligent flexible ankle stretching training on lower extremity spasm in patients with spinal cord injury. Methods From June,2021 to May,2024,28 patients with spinal cord injury were randomly divided into control group(n=14)and experimental group(n=14).Both groups received conventional rehabilitation treatment.On this ba-sis,the control group received manual extension treatment,and the experimental group received intelligent flexi-ble ankle stretching system training,for eight weeks.The modified Ashworth Scale(MAS),ankle dorsiflexion an-gle,Clinical Spasticity Index(CSI),max root mean square(RMSmax)of surface electromyography of gastrocne-mius medial head and vibration perception threshold(VPT)of great toe were compared. Results After treatment,MAS(χ2=10.378,P=0.035),ankle dorsiflexion angle(Z=-3.306,P<0.001),CSI(t=4.101,P=0.001)and RMSmax of gastrocnemius medial head(Z=-3.296,P<0.001)improved in the experimental group,while MAS(χ2=11.418,P=0.022),ankle dorsiflexion angle(Z=-1.986,P=0.047)and RMSmax of gas-trocnemius medial head(Z=-2.297,P=0.021)were better in the experimental group than in the control group.Although VPT was improved after treatment,no significant difference was found within and beteen groups(P>0.05). Conclusion The intelligent flexible ankle stretching training could improve the lower limb muscle spasticity in patients with spinal cord injury,and may be benefit for foot proprioception.

Objective To evaluate the performance of axial-pattern composite tissue flap in the repair of skin defects after lip cancer resection.Methods From July 2012 to December 2017,8 patients with lip cancer were enrolled from Department of Dermatology,the Second Hospital of Jilin University.After lip tumor resection,the full-thickness defects were as long as 1/3 to 1/2 length of the lip,and were repaired with axial-pattern composite tissue flaps based on labial arteries.Results All the axial-pattern composite tissue flaps survived after the surgery.During the follow-up of 6 months to 5 years,no tumor recurrence was observed in the 8 patients,the shape and function of lips were improved,and the patients were satisfied.Conclusion Skin defects after lip cancer surgery can be repaired with axial-pattern composite tissue flaps based on labial arteries,which can restore the anatomical structure and aesthetic function of the lip well.

Objective To establish a post management performance appraisal method for orthopedic nurses, and explore its practical effects. Methods The balanced scorecard performance tool was used in combination with two rounds of expert consultation to establish the appraisal index system. It comprises assessment indexes of four dimensions, dimension weight and index score value. Monthly performance appraisal value was calculated based on the nurses′post coefficient, and the health factor was used to reduce nurses′dissatisfaction in performance appraisal. Four orthopedics departments were selected for a one-year trial, with the results evaluated in the end. Results A comparison made before and after this appraisal found an increase of the nurses′ job satisfaction (9 out of 13 survey items, P <0.05), higher inpatient satisfaction (P<0.05), and higher nursing quality ( number of adverse nursing events Ⅳ, P <0.05). Other indicators include more nurses participate in learning and theoretical researches ( number of papers published, number of lecture hosts and the number of participants in nursing competition ( P <0.05 ). Conclusions The performance appraisal system of orthopedic nurses can improve nursing quality and patient satisfaction, effectively mobilize the initiative and creativity of nurses, and meet the characteristics of nurse post management, proving a success in use.

Aim To study the antipsychotic effects of l-Scoulerine ( l-SLR) . Methods NMDAreceptorantag-onist MK-801 was used to induce the positive and neg-ative symptoms of schizophrenia and cognitive impair-ment in animal models. The effects of l-SLR were eval-uated on schizophrenia induced by MK-801 and on ex-trapyramidal system. Results l-SLR (10,15 mg · kg - 1 , ip) could suppress pre-pulse inhibition damage in rats induced by MK-801 (0. 3 mg·kg - 1 , ip); l-SLR(30 mg·kg - 1 , ip) could inhibit climbing behav-iors in mice induced by apomorphine, which suggested that l-SLR had significant inhibiting effects on the posi-tive symptoms of schizophrenia by MK-801 and apo-morphine. l-SLR could also induce social contact inhi-bition and cognitive impairment induced by MK-801 (0. 2 mg · kg - 1 , ip), which proposed that l-SLR could improve the negative symptoms and cognitive im-pairment by MK-801. Catalepsy in mice could be caused by the treatment dose of haloperidol (0. 8 mg· kg - 1 , ip), not by that of l-SLR(30 mg·kg - 1 , ip). Conclusion I-SLR has significant effects on the posi-tive and negative symptoms of schizophrenia and cogni-tive impairment and, the effect of l-SLR under effective dose on extrapyramidal system is obviously much less than that of haloperidol and l-SPD.

Recently the studies on mosquito genomics, transcriptomics and small RNAomics developed rapidly with the novel biotechnologies of the next generation sequencing techniques. The genome sequences of several important vector mosquitoes including Anopheles gambiae, Culex quinquefasciatus, and Aedes aegypti have been published. The genome sizes vary among the different species of mosquitoes and are consistent with the number of the repeat regions. The released genome sequences facilitate gene cloning and identification as for OBP, OR and dsx genes. Transcriptomics provides a useful tool for functional analyses of the mosquito genes, and using this technique, the molecular basis of mosquito blooding, gland proteins and diapauses have been explored. Studies on small RNAomics suggest important roles of miRNAs and piRNAs in ovary development, blood digestion, and immunity against virus infection. The studies on mosquito omics have generated a big data platform for investigation of vector biology and vector-transmitted disease prevention.

Objective To observe the influence of the theory of planned behavior (TPB) in teaching patients with cervical spondylosis about their disease.Methods A hundred cervical spondylosis patients were assigned according to their admission order into an experimental or a control group.The control group received conventional health education and health education materials, including oral health education.With the intervention group,the TPB was used to design their nursing, and they received behavioral intervention addressing attitude, subjective norms and behavior control.Both groups were assessed for the degree of pain using a six-point pain score, health behavior, and recurrence, before the experiment and after 6 months.Results After six months both groups had significantly improved pain scores, but the average improvement in the intervention group was significantly greater.Their health behavior was also significantly better except for the prevention of pharyngeal infection and keeping warm.Conclusions The TPB can significantly relieve the pain and improve the health behavior of spondylosis patients, and reduce the recurrence rate.

Purpose To discuss the TCR gene rearrangements in the diagnosis of T-cell lymphomas. Methods Formalin-fixed and paraffin-embedded samples including 30 cases of T-cell lymphomas and 30 cases of reactive lymphoid hyperplasia were chosen for ex-tracting genomic DNA and PCR amplification using 56 BIOMED-2 primers. PCR products were analyzed by heteroduplex and polyacryl-amide gel electrophoresis. Results In all 30 cases of T-cell lymphomas, 25 cases (83. 3%) showed TCRβ gene monoclonal rear-rangements, 28 cases (93. 3%) of TCRγ gene monoclonal rearrangements, 4 cases (13. 3%) of TCRδ gene monoclonal rearrange-ments. 29 cases (96. 7%) with TCRβ+TCRγ+TCRδ gene monoclonal rearrangements were detected. but no clonal TCR gene rear-rangements were found in 30 cases of reactive lymphoid hyperplasia. Conclusions The detection of TCR gene rearrangements using BIOMED-2 primers is a useful assistant method for the diagnosis of T-cell lymphomas.
