Objective To investigate the immediate brain effect of acupuncture at Fengchi using amplitude of low-frequency fluctuation(ALFF)and functional connectivity by the resting-state functional magnetic resonance imaging(rs-fMRI)in patients with posterior circulation ischemia vertigo(PCIV).Methods Twenty patients with PCIV were enrolled.The dizziness handicap inventory(DHI)was used to evaluate the severity of vertigo.The patients were randomly divided into acupuncture group and sham acupoint acupuncture group.Rs-fMRI scan was performed before and after acupuncture.MATLAB-based DPABI 6.1 software was used to analyze rs-fMRI data.Correlation analysis was used between the altered ALFF values and DHI scores.The regions of altered ALFF were taken as seeds to analyze functional connectivity.Results Compared with the sham acupoint acupuncture group,the increased ALFF values were mainly located on the left precuneus,left superior frontal gyrus and left caudate nucleus after acupuncture in the acupuncture group;the decreased ALFF values were mainly located on the left cerebellum and right inferior occipital gyrus.The ALFF value of the left superior frontal gyrus was negatively correlated with the DHI score(P=0.04).The increased functional connectivity was mainly found between left precuneus and the right middle frontal gyrus,the right superior frontal gyrus,the decreased functional connectivity was mainly found between left precuneus and the bilateral paracentral lobule and right cerebellum.Conclusion The ALFF value and functional connectivity are different before and after acupuncture,indicating that the vestibular network,visual and motor brain regions functional activities are changed after needling at Fengchi,which may be the brain functional basis of Fengchi for vertigo in PCIV.

Objective:To investigate the effect of right stellate ganglion block (RSGB)-serratus anterior plane block (SAPB) combined with general anesthesia in thoracoscopic radical resection of lung cancer.Methods:A total of 90 patients who planned to undergo thoracoscopic radical resection of lung cancer in Xiangya Changde Hospital from March 2020 to September 2021 were prospectively selected and divided into 3 groups by random number table method: general anesthesia group (G group), (SAPB)+ general anesthesia group (SG group), RSGB+ SAPB+ general anesthesia group (RSG group), 30 cases in each group. The SG group received SAPB on the operative side before general anesthesia, and the RSG group received RSGB+ SAPB on the operative side before general anesthesia. After the blocking effect was determined, all patients were given general anesthesia in the same scheme according to their weight, and patients were given patient-controlled intravenous analgesia (PCIA) after surgery. The mean arterial pressure (MAP) and heart rate (HR) were recorded before anesthesia (T 0), before intubation (T 1), 1 min after intubation (T 2), 5 min after intubation (T 3), at extubation (T 4) and 5 min after extubation (T 5). The intraoperative dosage of remifentanil, incidence of nausea and vomiting (PONV) within 24 hours after surgery, number of additional PCIA within 24 hours, the Visual Analogue Scale (VAS) of static and dynamic pain, the Bruggrmann Comfort Scale (BCS) and Richard Campbell Sleep Questionnaire (RSCQ) 24 hours after surgery were recorded. Results:Compared with T 0, the MAP and HR in 3 groups were increased 1 min after intubation (T 2) and at extubation (T 4), but the increases in RSG group were significantly less than those in G and SG groups (all P<0.05). The remifentanil dosage, PONV incidence and PCIA supplemental times in SG and RSG groups were less than those in G group, and the BCS score and RSCQ score were higher than those in G group (all P<0.05); the BCS score and RSCQ score in RSG group were higher than those in SG group (all P<0.05). Conclusions:RSGB+ SAPB combined with general anesthesia in thoracoscopic radical resection of lung cancer has little circulation fluctuation, good postoperative analgesia effect, less adverse reactions and high comfort level.

Objective:To explore the prognostic value of tumor deposits (TD) by number and anatomical distribution in gastric cancer (GC) patients without lymph node metastasis.Methods:From Aug 2012 to Aug 2018 all 91 GC patients undergoing radical gastrectomy and without nodal metastasis at Yijishan Hospital of Wannan Medical College were enrolled in this study. Patients were divided into L1, L2, and L3 groups according to the number of TD and into Q1 and Q2 groups according to the anatomical regions of the TD.Results:The 3-year overall survival (OS) rates of groups L1, L2, and L3 were 58.9%, 52.1%, and 31.5%, respectively ( χ2=9.769, P=0.008). The 3-year OS rates of groups Q1 and Q2 were 58.9% and 7.1% ( χ2=46.310, P<0.001). The number of TD, their distribution, neural invasion, vascular invasion, tumor size, and pT stage were all related to prognosis by univariate analysis (all P<0.05). Tumor size>4 cm ( HR=2.460, 95% CI:1.307-4.629, P=0.005), distribution of TD (non-perigastric)( HR=3.959, 95% CI:2.077-7.545, P<0.001), neural invasion ( HR=4.299,95% CI:1.953-9.461, P<0.001), and pT 4 stage ( HR=2.283, 95% CI:1.250-4.171, P=0.007) were independent risk factors for prognosis by multivariate analysis. Conclusion:The distribution of TD (non-perigastric) is an independent risk factor for poor prognosis in gastric cancer patients after radical gastrectomy and with negative lymph node metastasis.

OBJECTIVETo study the effects of a Gold Belt (GB, a traditional Chinese herbal medicine) combined with methyl-prednisolone (MP) on the motor function and brain-derived neurotrophic factor (BDNF) expression in rats with contusive spinal cord injury (SCI).

METHODSThirty adult female SD rats were randomly divided into 5 equal groups, namely the sham-operated group, SCI group, SCI with MP treatment group (MP group, with intramuscular injection of 50 mg/kg MP within 8 hours after SCI and then dosage reduced 10 mg/kg daily), SCI with GB treatment group (GB group, with intragastric gavage of GB 50 mg/kg once daily for 7 days), and combined GB and MP treatment group. The Basso, Beattie and Bresnahan (BBB) locomotor scale was used to evaluate the hindlimb motor function of the rats on days 1, 3, 7, 14, 21 and 28 after the injury. After the last evaluation the rats were sacrificed for immunohistochemistry to observe the localization of BDNF in the ventral and dorsal horn of spinal cord.

RESULTSBDNF were distributed mainly in neurons in the spinal cord grey matter ventral horn and dorsal horn of the rats. The number of BDNF-positive neurons and BBB scores in the combined treatment group were significantly higher than those in the other 4 groups (P<0.05).

CONCLUSIONGB combined with MP produces better therapeutic effects for treating SCI than GB or MP used alone, and such effects are probably related with enhanced BDNF expression in the spinal cord.

BACKGROUND:There are stil some controversies about lateral compression rotational y unstable pelvic ring injuries and fixed mode. OBJECTIVE:To evaluate the pelvic stability of locking plate fixation pelvic reconstruction repairing lateral compression rotational y unstable pelvic ring injuries. METHODS:We retrospectively analyzed 15 patients with unstable lateral compression rotational y unstable pelvic ring injuries treated with reconstruction locking plates fixation at Suzhou Xiangcheng People’s Hospital between November 2011 and November 2014. The Matta standard was used to evaluate the quality of fracture reduction. Clinical efficacy was evaluated by Majeed score. RESULTS AND CONCLUSION:Fifteen patients were fol owed up for 12-44 months (mean 24 months). According to the standard of Matta, 11 cases were excel ent, 2 cases were good, 2 cases were average, 0 case poor, and the excel ent and good rate was 87%. According to Majeed functional assessment, clinical function outcomes were graded as 9 cases excel ent, 3 cases good, 1 case average, 1 case poor;excel ent and good rate was 80%. There were no patient loss of reduction and internal fixation failure among these 15 patients in the final fol ow-up. No iatrogenic neurovascular injury occurred. Incision superficial infection was detected in 2 patients with a Morel-Laval ee lesion after subjecting to double-tube continuous negative pressure drainage, and healed after wound management. A large area of infection and skin necrosis did not occur. These results confirm that pelvic universal reconstruction locking plates in repair of lateral compression rotational y unstable pelvic ring injuries can maintain a strong and effective fixation. We should pay much attention to the cases of pelvic fractures combined with soft tissue injury around the pelvis.

This article explained that the evidence grading system occupied an important position in the evidence-based clinical practice guidelines. Through the comparative analysis on characteristics of clinical evidences between traditional Chinese medicine (TCM) and modern medicine, different possible establishment ideas of evidence grading system in TCM evidence-based clinical practice guidelines were proposed . The design for evidence grading standard of Chinese medical literature which reflected the academic characteristics of TCM was suggested.

Objective To explore the relationship between cholelithiasis and the function of sphincter of Oddi (SO). Methods To identify the existence of calculi, choledochoscopy was performed in patients 6 weeks after exploration of the common bile duct (CBD) and T tube drainage, in which 71 were patients with stones in gall bladder, CBD or intra-hepatic bile duct, and 9 with trauma of pancreas or liver.Biliary manometry was performed after choledochoscopy, and an additional manometry was applied after calculus removal if calculi were detected. The indices measured included SO basal pressure ( SOBP), amplitude of SO contractions (SOCA), frequency of SO contractions (SOF) and CBD pressure (CBDP). The patients with cholelithiasis were classified into cholecystolithiasis group, choledocholithiasis group, and hepatolithiasis group according to the position of calculi. Patients with trauma were assigned as the control group.Results All variables in 50 patients with choledocholithiasis were similar before and after the procedure.The variables in patients with cholecystolithiasis and choledocholithiasis had no difference from those of the control (P ＞ 0. 05 ). The SOBP and SOCA of patients in hepatolithiasis group were lower than those of the control group ( P ＜ 0. 05 ), while no difference in SOF was detected (P ＞ 0. 05 ). Conclusion The function of SO in patients with hepatolithiasis is abnormal ( decrease in SOBP and SOCA). Biliary manometry cannot be the reliable evidence for the existence of calculi in bile duct.

Objective To establish the canine model of esophageal variees caused by portal hyper-tension. Methods The model was established in 12 dogs with a side-to-side portacaval shunt, an ameroid constrictor around the portal vein and double ligation and cross suture of the cephalic part of the inferior vena cava (IVC), and the development of esophageal varices was confirmed 6 weeks later by endoscopy and portal vein angiography. Results The mean pre- and postoperative portal pressure were (11.0 ± 1.1) mm Hg and (22. 9 ± 1.2) nun Hg, respectively (P =0. 010). Endoscopy detected mild to moderate esophageal varices in all dogs, which was confirmed by portal vein angiography, and varices was also seen in abdominal wall. Conclusion Canine model of esophageal varices induced by portal hypertension can be established with the procedure.
