ObjectiveTo observe the analgesic efficacy and safety of Qihuang acupuncture theory combined with opioid analgesics in patients with moderate to severe cancer pain due to lung cancer. MethodsPatients with moderate to severe cancer pain from lung cancer were randomly divided into Qihuang acupuncture group and control group， with 33 cases in each group. The control group was treated with long-acting opioid analgesics at maintenance doses and supplementary analgesic medications as needed. In case of breakthrough pain， short-acting opioids were used for rescue. The Qihuang acupuncture group received Qihuang acupuncture treatment in addition to the treatment used in the control group， administered once every other day， with 3 sessions constituting one treatment course. The treatment duration for both groups was 5 days. The primary outcome was the change in pain intensity， measured using the numerical rating scale （NRS） before and after treatment， and the NRS change rate was calculated. Secondary endpoints included the daily NRS change rate， the Eastern Cooperative Oncology Group （ECOG） Performance Status （PS） score， the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire （EORTC QLQ-C30） score， and the 24-hour equivalent hydrocodone sustained-release tablet dose. Laboratory tests， including routine blood， urine， stool， liver function， and kidney function， were performed before and after treatment. Adverse events were recorded throughout the trial. ResultsAll patients completed the trial， and both groups showed a decrease in average NRS scores and PS scores after treatment， with the Qihuang acupuncture group showing lower average NRS scores and PS scores than the control group （P＜0.05 or P＜0.01）. After treatment， the NRS change rate in the Qihuang acupuncture group was （0.42±0.17）， significantly higher than that in the control group （0.14±0.27， P＜0.01）. The daily NRS change rate during treatment was also higher in the Qihuang acupuncture group compared to the control group （P＜0.01）. The Qihuang acupuncture group showed an increase in overall health status and functional scores in the EORTC QLQ-C30， and a decrease in symptom scores for fatigue， nausea and vomiting， pain， dyspnea， insomnia， appetite loss， constipation， and financial difficulties. In contrast， overall health status and constipation scores in the control group increased， while scores of fatigue， nausea and vomiting， pain， and appetite loss decreased （P＜0.05 or P＜0.01）. After treatment， the 24-hour equivalent hydrocodone sustained-release tablet dose did not show significant difference in the Qihuang acupuncture group （P＞0.05）， while the control group showed a significant increase in the 24-hour dose （P＜0.01）. No significant abnormalities were observed in laboratory tests before and after treatment in either group. During the study， the incidence of nausea and vomiting as well as constipation in the Qihuang acupuncture group was both 3.03% （1/33）， while the incidence in the control group was 27.27% （9/33） and 36.36% （12/33）， respectively， with the Qihuang acupuncture group showing significantly lower incidence （P＜0.01）. No serious adverse reactions were observed in either group. ConclusionQihuang acupuncture therapy combined with opioid analgesics is more effective than using opioids alone in relieving pain in patients with moderate to severe cancer pain due to lung cancer. It can improve the patients' physical condition and quality of life， reduce the dose of opioid analgesics， and has good safety.

Electroencephalography(EEG)is a noninvasive brain-activity measurement technique that uses electrodes placed on the scalp to record the bioelectrical activity of neurons in the cerebral cortex the sum of excitatory and inhibitory synaptic activity.EEG can reveal the function of different brain regions and the complex intercommunication.In recent years,many studies have focused on the use of EEG to ana-lyze the mechanism of general anesthetics and to measure the depth of anesthesia.The connectivity analysis methods of EEG are introduced and their application on anesthetic drugs are reviewed in order to explore other potential EEG analysis methods of drug action mechanism in the future.

Objective To investigate the consistency analysis between multimodal MRI in determining vaginal involvement and parametrial infiltration in cervical cancer patients and pathological examination.Methods Ninety-two patients with cervical cancer were regressively selected and who underwent preoperative multimodal MRI examination.Using pathological results as the gold standard,the receiver operating characteristic(ROC)curve was used to analyze the diagnostic efficacy of conventional MRI,diffusion weighted imaging(DWI)and dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)alone and in combination in predic-ting vaginal involvement and parametrial infiltration.Results(1)Vaginal involvement:the diagnostic sensitivity of conventional MRI was 65.96％,the specificity was 91.11％,and the area under the curve(AUC)was 0.775[95％confidence interval(CI)0.676-0.873].The sensitivity of DCE-MRI was 61.70％,the specificity was 95.56％,and the AUC was 0.797(95％CI 0.702-0.892).The sensitivity of DWI was 72.34％,the specificity was 88.89％,and the AUC was 0.817(95％CI 0.725-0.908).At the optimal cut-off point,the sensitivity of parallel combined detection was 97.87％,the specificity was 93.33％,and the AUC was 0.956(95％CI 0.907-0.918).(2)Parametrial infiltration:the diagnostic sensitivity of conventional MRI was 67.24％,the specificity was 91.18％,and the AUC was 0.783(95％CI 0.688-0.879).The sensitivity of DCE-MRI was 62.07％,the specificity was 94.12％,and the AUC was 0.781(95％CI 0.686-0.875).The sensitivity of DWI was 75.86％,the specificity was 97.06％,and the AUC was 0.865(95％CI 0.788-0.941).At the optimal cut-off point,the sensitivity of parallel combined detection was 98.28％,the specificity was 91.18％,and the AUC was 0.947(95％CI 0.888-1.000).Conclusion Combined multimodal MRI can improve the positive detection rate of vaginal involve-ment and parametrial infiltration in patients with cervical cancer,allowing for timely treatment adjustments,improved quality of life and longer survival.

Objective To investigate the effect of rehabilitation training combined with acupuncture ( RTA) on upper limb function of stroke patients by Kinect. Methods Stroke patients with upper limb dysfunction werrandomly divided into control group (rehabilitation training) and treatment group ( RTA), with 15 cases in each group. The modified Barthel Index ( MBI), Fugl Meyer assessment ( FMA), and Wolf motor function test (WMFT) were compared between two groups before and after treatment. The changes in motor time ( MT), motor unit number (MUN), index of curvature (IC), elbow flexion angle (EFA), shoulder flexion angle (SFA),and shoulder adduction angle ( SAA) during three actions, namely, placing forearm on the table, extending elbow and drinking water, were evaluated by Kinect and then compared between two groups before and after treatment. Results After 6 weeks of intervention, the scores of MBI, FMA, WMFT and elbow extension in treatment group were higher than those in control group (P<0. 05). The scores of MBI, FMA, WMFT and three actions after treatment were higher than those before treatment (P<0. 05). For three actions, the improvement of MT, MUN, IC, EFA, SFA, and SAA in treatment group were better than those in control group ( P< 0. 05). Compared with pre-treatment, for the action of forearm placement on the table and elbow extension, both treatment group and control group showed an increase in EFA (P<0. 05), and a decrease in MT, MUN, IC, SFA and SA (P<0. 05). For the action of drinking water, both treatment group and control group showed an increase in EFA and SAA (P< 0. 05), and a decrease in MT, MUN, IC and SAA ( P< 0. 05). Conclusions RTA can improve the upper limb function of stroke patients. Kinect can accurately reflect the changes in upper limb function of stroke patients, and it is suitable for clinical work.

Objective To observe the clinical efficacy of Qihuang needle therapy in treating knee osteoarthritis.Methods Sixty knee osteoarthritis patients were randomly divided into treatment group and control group,30 cases in each group.The treatment group was given Qihuang needle therapy and the control group was given conventional acupuncture therapy.After treatment for 10 days,we evaluated the curative effect of the two groups by the scores of the simplified McGill pain scale (MPQ) and the Lysholm knee scoring criteria.Results (1) After treatment for 10 days,the symptoms of pain,swelling,stiffness,and inhibited bending and stretching of knee joints of the two groups were relieved.Pain rating index (PRI),visual analogue scale (VAS) scores and present pain intensity (PPI)of MPQ in the two groups were obviously decreased,while Lysholm knee scores were markedly increased(P ＜ 0.01 compared with those before treatment),and the effect of the treatment group was superior to that of the control group (P ＜ 0.05).(2) The total effective rate of the treatment group was 86.67％,and that of the control group was 66.67％,the difference between the two groups being significant (P ＜ 0.05).Conclusion Qihuang needle therapy is effective for the treatment of knee osteoarthritis,with the advantages of shorter treatment course,better therapeutic effect and being more practical.

Objective To compare the reliability and effectiveness of anterolateral thigh flap with double vein anastomosis or one vein anastomosis for reconstruction of head and neck defects.Methods Two hundred and sixty four cases of anterolateral thigh flap transfers for head and neck reconstruction from January,2013 to September,2013 in the Second Xiangya Hospital of Central South University were reviewed.260 patients were randomly divided into 2 groups.In the experimental group,there were 138 patients 140 cases of anterolateral thigh flap with one vein one artery anastomosis.In the control group,there were 122 patients 124 cases of anterolateral thigh flap with double vein one artery anastomosis.Results Among 264 anterolateral thigh flaps,the overall success rate of free flap was 98.1％ (259/264),5 free flaps were lost.In the experimental group,there were 6 free flaps occurred venous thrombosis,two of them were lost.In the control group,there were 5 cases occurred venous thrombosis,three of them were lost.No arterial thrombosis occurred in both groups.The time of micromanipulation was 18 to 101 min,with the average of 47 min in the experimental group.In the control group,the time was 45 to 133 min,with the average of 71 min.(P =0.0003).Conclusion Anterolateral thigh flap with one vein one artery anastomosis for head and neck reconstruction did not affect the survival rate but it can absolutely reduce the operation time.

Objective To summarize the application of 909 anterolateral thigh myocutaneous flaps in the repair of oral and maxillofacial defects and to examine their benefits in maxillofacial reconstruction of these defects.Methods Patients were recruited from January 2004 to December 2012 in the Department of Oral and Maxillofacial Surgery of the Second Xiangya Hospital of Central South University.All patients underwent reconstructive surgery with anterolateral thigh myocutaneous flaps,and patient age ranged from 19 to 81 years with a mean of 51.2 years.There were 761 flaps showing single lobe and 148 flaps showing a multi-island pedicle.The largest area among the single flaps was 28 cm× 12 cm,and the smallest was 4 cm× 2 cm.Results Among the 909 transferred flaps,882 survived and 27 showed necrosis,with a survival rate of about 97.0％.The common complications at flap donor site were poor wound healing 9.6％(87/909),localized paresthesia 61.0％(500/820),and altered quadriceps force 15.0％(123/820).No case was presented with local serious complications,and 90％ of the patients achieved good functional recovery and aesthetically acceptable results after the reconstruction by anterolateral thigh myocutaneous flaps.Conclusions The anterolateral thigh myocutaneous free flaps are more suitable for oral and maxillofacial defects than other flaps and should be preferred.

Objective To identify the factors that were predictive of outcome and to determine the effect of age on perioperative complications.Methods Reviewed the records of 1 100 consecutive patients who underwent anterolateral thigh flap free flap transfers for oral and maxillofacial cancer surgery defects between February 2002 and March 2013.All patients were divided into two groups:A group (＜60 years old) and B group (≥60 years old).Postoperative complications were analyzed from all patients.Results There were 781 cases in A group and 319 in B group.The overall success rate was 97.2％(1 100/l 132)[97.3％ (781/803) in A group,97.0％ (319/329) in B group,P＞0.05].The overall complication rate was 27.5％ (302/1 100)[25.9％ (202/781) in A group,31.3％ (100/319) in B group,P=0.064].Multivariate Cox regression analyses revealed that American Society of Anesthesiologists (ASA) status (P＜0.001),operation time (P=0.021) and comorbidity (P=0.002) were the independent factor for the complication of patients.However,age (P＞0.05) was not an independent factor for the complication of patients.Conclusions Oral and maxillofacial reconstruction using anterolateral thigh flap free flaps in elderly patients can achieve similar outcomes as in younger patients.Controlling operative time is very important in reducing postoperative complications and improving the results of surgery.

OBJECTIVETo seek a new method for reconstructing bilateral intemrnal jugular vein invaded by metastasis lymph node in advanced oral cancer patients.

METHODSA combination of microvascular anastomosis and longitudinal constriction suture venoplasty was performed to reconstruct internal jugular vein. We resected the part of the bilateral internal jugular vein of advanced oral cancer patients invaded by metastasis lymph node and used the external carotid vein to reconstruct the internal jugular vein. A part of the vessel wall of the internal jugular vein could also be resected to reconstruct the vein. Longitudinal constriction suture venoplasty could slowly narrow the lumen diameter of the internal jugular vein. Thus, difference in anastomosis diameter should be avoided because it generates eddy currents and subsequently causes blood clots. A total of five advanced cases of oral squamous cell carcinoma were involved in this study. We performed bilateral radical neck dissection on all patients to reconstruct the internal jugular vein and observed their postoperative conditions.

RESULTSPostopera-tive follow-up of 5 months to 19 months was performed on all patients. Doppler or CT angiography and related tests showed no internal jugular vein thrombosis. No patient with facial edema, throat swelling, cerebral edema, and high intracranial pressure or other serious complications caused by blocked venous blood was observed. The one-year survival rate of five patients was 60% (3/5).

CONCLUSIONMicrovascular anastomosis combined with longitudinal constriction suture venoplasty is a new method for reconstructing internal jugular vein. This method was proved successful and clinically feasible.
