Mid-ventricular hypertrophic obstructive cardiomyopathy (MVHOCM) is a rare type of cardiomyopathy thatcan be accompanied by apical aneurysm.We presented here a case report of MVHOCM with cornary artery disease.The sixty-fouryears old man was sent to hospital because of ventricular tachycardia.Large inversion T wave was showed on electrocardiography in the presence of abnormal coronary arteries and normal cardiac enzyme.Echoeardiogmphy showed an hourglass appearance of the leftventricle with an aneurysm in the apex and a pressure gradient between the outflow tract of left ventricle and the middle of the leftventricle was revealed by left-heart catheterization.

The examinations of optical coherence tomography (OCT) images were obtained in 136 patients. Lactated Ringer's solution or physiological saline was used randomly as perfusate. Their electrocardiogram and cardiac enzymes were acquired to compare the safety and image quality of two perfusates.The incidence of ventricular arrhythmia and rise of cardiac enzymes were lower in the lactated Ringer's solution group than those in the physiological saline group.Yet the image quality of OCT had no difference.The use of lactated Ringer's solution as perfusate instead of physiological saline in OCT examination may protect the ischemic myocardium and reduce the incidence of complications.

OBJECTIVE: To investigate the correlation of bone mineral density changes with vertebral deformation and clinical manifestations in patients with cervical spondylotic myelopathy.METHODS: A total of 42 cervical spondylotic myelopathy patients who received treatment at the Department of Sports Medicine,First Affiliated Hospital of Anhui Medical University from January to June 2009 were selected and randomly divided into the normal (n=20) and lower bone density (n=22) groups. The cervical lateral of the C_(3-8) spinal canal, sagittal diameter of vertebral body ratio, vertebral body deformation index in all cases was measured, and the clinical manifestations between two groups were compared.RESULTS: The cervical (C_3, C_4, C_5, C_6) sagittal diameter of vertebral body ratios of lower bone density group were significantly decreased than those of the normal group (P ＜ 0.05, or P ＜ 0.01), and the cervical (C_3, C_4, C_5, C_6)vertebral body deformation indexes of the two groups showed no significant difference (P ＞ 0.05); While the clinical manifestations (symptoms and physical signs) was significantly greater in the lower bone density group than the normal group (P ＜ 0.05).CONCLUSION: Cervical myelopathy can cause osteoporosis in patients with vertebral bone hyperplasia, spinal stenosis, in particular, the clinical manifestations are more obviously in lower bone density patients.

Studies on the origin of the afferent acetylcholinesterase-containing fibres of the nucleus accumbens in the brain stem of 27 rats were carried out by retrograde fluorescent labeling combined with AChE histochemistry. DAPI or Pr was injected into the nucleus accumbens. The animals survived for 2.5-3 days. DFP was injected intramuscularly 6 to 8 hours before left intraventricular perfusion by 10％ formalin-containing phosphate buffer solution (0.1mol/L, pH 7.4). The frozen serial transverse sections of the brain stem were incubated in Karnovsky-Roots solution. The fluorescent retrograde labeled cells with AChE reaction-positive products were traced under OLYMPUS fluorescence microscope and light microscope simultaneously. The results were as follows: (1) On the ipsilateral side, the retrograde fluorescent labeled cells with AChE reaction-positive products were found in the following nuclei: area ventralis tegmentalis (AVT), substantia nigra (SN), nucleus raphes mesencephali caudalis(cmr), nucleus tegmenti pedunculopontinus(tpt), nucleus raphe dorsalis(dr), nucleus centralis superior (cs), nucleus reticularis tegmenti pontis(rtp), Locus ceruleus (Lc), nucleus tractus solitarus(tsol), nucleus raphe pallidus (rpa), nucleus reticularis paramedianus (rpm), subnucleus reticularis ventralis(rv), nucleus reticularis lateralis(rL). (2) On the contralateral side, a few of the above mentnioned cells were also found in AVT, SN, dr, cs, and tsol.

Objective To compare the effect of percutaneons coronary interventions (PCI) combined with polydanshinolate on myocardial reperfusion with PCI combined with regular medicine in patients with acute myocardi-al infrarction ,and whether polydanshinolate would decrease no-reflow,improve the myocardial micro-circulation and the ventricular remodeling and clinical end-point events at the sixth month. Methods Random,parallel control and prospective clinical design was used in the current study. Sixty eligible patients for PCI, who were diagnosed as first-time acute myocardial infrarction with ST stage increasing,were recruited in the study with informed consent. All par-ticipants were divided into two groups randomly. Group A was treated with PCI combined with polydanshinolate, group B was treated with PCI combined with regular medicine. The participants were followed up for six months. The resolution of the sum of ST segment elevation (sum STR) ,corrected TIMI frame count (CTFC) and myocardial con-trast echocardiography (MCE) were used to assess myocardial perfusion. Bleeding events, heart function and major adverse cardiac events (MACE) were observed during hospitalization and follow-up visit. Results No significant difference was observed between two groups on the clinical condition and the results of emergency CAG and PCI. Compared to group B,the incidence of TIMI grade 3 was significantly higher in group A (90.0% vs 63.3% ,χ~2 = 4.565, P=0.0326). Sum STR one hour after PCI in group A was siguificanfly higher than that in group B (80.0% vs 50.0%, χ~2=4.689, P=0.0304). CTFC after PCI also differed significantly between the two groups (24.1±8.3 vs 33.4±15.9 respectively,P=0.0062). Localized myocardial blood flow 48 hours after PCI showed no significant difference between the two groups (P>0.05), whereas both increased at the 7th day after PCI (5.85±1.26 vs 2.09±1.85,t=9.2008,P<0.0001 ;3.95±1.35 vs 1.95±1.29,t=5.8666,P<0.0001) ,and there were signifi-cant difference between the two groups (P<0.05). No significant difference of LVEF, LVEDV, LVESV were found between the two groups during the hospitalization and follow-up visit after 6 months (P>0.05). The incidences of cardiovascular events and severe heart failure during hospitalization and follow-up visit in group A were significantly lower than that in group B (P<0.05 ). Conclusions Polydanshinolate addition to PCI could reduce no reflow phe-nomenan in patients of acute myocardial infrarction, improve myocardial reperfusion, and furthermore, decrease cardi-ovascular events and ameliorate prognosis.

Objective To determine any relationship among detrusor wall thickness (DWT),bladder capacity (BC) and neurogenic lower urinary tract dysfunction (NLUTD),and to study the clinical implications of using DWT to predict the risk of renal injury after spinal cord injury (SCI).Methods Forty-eight adults with NLUTD due to SCI were recruited for the SCI group,and another 41 healthy adults formed a control group.Both groups underwent urodynamic evaluation and maximum bladder capacity (MBC) detection.The DWT of all subjects was measured by ultrasound imaging of the anterior bladder wall.Thereafter,the SCI group was divided into low and high risk subgroups based on the results of the urodynamic tests.Patients with detrusor leak point pressure ＜40 cmH2O were classified as low risk.Results At MBC,the average DWT in the SCI group was (0.97 ± 0.31)mm and (0.59 ± 0.08)mm in the control group,demonstrating a significant difference in DWT between patients with NLUTD and normal adults.The average DWT among the patients with type A detrusor sphincter dyssynergia was (1.10 ± 0.34)mm,which was significantly higher than among the patients with external urethral sphincter contraction without detrusor contraction (type C).DWT was significantly correlated with detrusor leak point pressure.A DWT of 0.87 mm (sensitivity 89.5％,specificity 58.6％) could be used as a critical point for predicting risk of renal injury in patients with NLUTD.Conclusions DWT is significantly greater among SCI patients with NLUTD and it correlates positively with detrusor leak point pressure.DWT could be used as a risk predictor for renal injury in patients with NLUTD due to SCI.

Objective To investigate the effectiveness of botulinum toxin A (BTX-A) injection to the external urethral sphincter guided by ultrasound in the treatment of various types of lower urinary tract dysfunction.Methods Twenty-two patients with urinary retention caused by neurological dysfunction (neurogenic bladder) were recruited,of which 18 were men and 4 women.They had various types of lower urinary tract dysfunction including detrusor external sphincter dyssynergia (DESD) in 7,nonrelaxing urethral sphincters in 5,and detrusor underactivity in 10.BTX-A (100 U) was injected into the external urethral sphincter at three different points guided by ultrasound.Clinical effects and urodynamic parameters were compared at baseline and after treatment.Results After treatment the urinary function and urodynamic parameters in each group improved significantly compared with the baseline.Maximum efficacy was observed at the 4th week.In the DESD group,3 patients (43％) had an excellent result and 3 (43％) had significant improvement; in the nonrelaxing sphincter group 3 (60％) had excellent results and 2 (40％) showed significant improvement; in the detrusor underactivity group 5 (50％) had excellent results and 3 (30％) had significant improvement.There were no obvious side effects.Conclusions BTX-A injections guided by ultrasound can accurately locate the external urethral sphincter.It is a simple and repeatable method for the treatment of lower urinary tract dysfunction.

Objective: To investigate the clinical efficacy of laparoscopic stomach intestinal pylorus sparing surgery (SIPS) in the treatment of severe obesity. Methods: The retrospective and descriptive study was conducted. The clinical data of 5 patients with severe obesity who were admitted to the China-Japan Union Hospital Affiliated to Jilin University from October to November 2018 were collected. There was 1 male and 4 females, aged from 18 to 55 years, with an average age of 33 years. All the 5 patients underwent laparoscopic SIPS. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) follow-up. Follow-up was performed by outpatient examination, telephone interview and Wechat up to February 2019, including general condition, changes in body weight, body mass index, waistline, blood pressure, percentage of excess weight loss, fasting plasma glucose, glycosylated hemoglobin, blood lipid, and uric acid at 3 months after surgery. Measurement data with normal distribution were represented as Mean±SD, and they were tested with Hotelling T² test. Measurement data with skewed distribution were represented as M (range). Results: (1) Surgical situations: 5 patients underwent successfully laparoscopic SIPS under clear surgical field, without obvious bleeding, conversion to open surgery or perioperative death. The operation time was 240 minutes (range, 165-345 minutes). (2) Postoperative situations: the time to initial out-of-bed activity, time to first and flatus, and time to initial drinking and liquid intake were 2 days (range, 2-3 days), 3 days (range, 2-3 days), and 3 days (range, 3-4 days), respectively. On the third day after surgery, all the 5 patients were confirmed anastomotic patency, without gastric leakage, stenosis, or obstruction by upper gastrointestinal contrast. The abdominal drainage-tube was removed on the fourth day after feeding without obvious discomfort and foreign substances extraction from the drainage-tube. The duration of postoperative hospital stay was 6 days (range, 6-7 days). (3) Follow-up: 5 patients with severe obesity were successfully followed up for 3 months. During the follow-up, one patient had significantly increased frequency of defecation, roughly 5-8 times a day, especially after eating greasy food. According to the dietary guidance of the case manager, diarrhea was improved significantly after reducing the intake of oily food. Of the 5 patients with severe obesity, color doppler ultrasonography examination revealed that cholestasis was found in 2 patients at 3 months after operation, which may be related to significant weight loss, ratio imbalance of bile acid to and cholesterol, intestinal microbiota, injury of vagus nerve, significant increasing in mucin of gallbladder, and without oral ursodeoxycholic acid as prescribed by the doctor. The body weight, body mass index, waistline, systolic blood pressure, and diastolic blood pressure of 5 patients with severe obesity were (100±15)kg, (36±4)kg/m^2, (111±10)cm, (130±12)mmHg (1 mmHg=0.133 kPa), and (78±14)mmHg at 3 months after operation, respectively, showing significant differences compared with these of preoperation (F=61.631, 75.558, 87.045, 9.501, 16.248, P<0.05). The percentage of excess weight loss was 44%±9%. Among the 5 patients with severe obesity, the fasting plasma glucose of 2 patients with type 2 diabetes mellitus decreased from 9.55 mmol/L and 13.49 mmol/L to 5.18 mmol/L and 5.62 mmol/L after operation, respectively. Level of glycated hemoglobin decreased from 10.0% and 9.9% to 5.2% and 6.2% after operation, respectively. In the 2 patients with hyperlipidemia, one patient with hypertriglyceride had level of triglyceride, total cholesterol, and low density lipoprotein increased from preoperative 2.24 mmol/L, 4.84 mmol/L and 2.92 mmol/L to 2.47 mmol/L, 6.68 mmol/L and 5.51 mmol/L after operation, another patient with hypercholesterol had cholesterol level decreased from preoperative 5.97 mmol/L to postoperative 5.75 mmol/L after operation. In the 3 patients with hyperuricemia, two patients had the uric acid decreased from 404 μmol/L and 484 μmol/L to 319 μmol/L and 417 μmol/L after operation, respectively, one had the uric acid increased from 531 μmol/L to 674 μmol/L after operation. Conclusions Laparoscopic SIPS has a significant short-term effect on patients with severe obesity, but its long-term safety and efficacy need to be further followed up.

Obesity can not only lead to various metabolic diseases such as non-alcoholic fatty liver, hypertension, hyperlipidemia, diabetes, and cardiovascular disease, it is also closely related to the occurrence and development of heart failure. Heart transplantation is the ultimate treatment for patients with heart failure. However, heart failure patients with obesity are usually excluded from the list of heart transplants. That is to say, obesity is considered a contraindication for heart transplantation. The traditional weight loss methods, including lifestyle interventions and medications, can not effectively alleviate obesity and its comorbidities because of their limited effect and time-consuming. In addition, weight-loss drugs cannot be used in heart transplantation because they can affect the absorption of immunosuppressive drugs. At present, metabolic surgery has become the most effective method for the treatment of obesity and its comorbidities, and is now gradually applied in the field of heart transplantation most of the heart failure patients with obesity meet the standards of heart transplantation after metabolic surgery, greatly increasing the transplantation rate as well as obesity, obesity-related metabolic diseases, and cardiac function were significantly improved, even some patients with heart failure no longer need heart transplantation after their cardiac function has been significantly improved. However, the application of metabolic surgery in the field of heart transplantation has not yet reached a consensus, and only a few reviews on this topic have been published. In this article, the application status and prospects of metabolic surgery in the field of heart transplantation are reviewed so as to provided reference for clinical practice.

Objective:To investigate the clinical efficacy of laparoscopic biliopancreatic diversion with duodenal switch (BPD-DS) for obesity.Methods:The retrospective and descriptive study was conducted. The clinical data of 10 patients with obesity who were admitted to the China-Japan Union Hospital Affiliated to Jilin University from September 2019 to January 2020 were collected.There were 7 male and 3 females, aged (32±9)years. Patients underwent laparoscopic BPD-DS. Observation indicators:(1) intraoperative and postoperative situations;(2) follow-up.Follow-up was performed by telephone interview and wechat up to July 2020, to detect complications, physical index, remission of preoperative comorbidity and blood biochemical index at 3 months and 6 months after operation. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Repeated data were analyzed using the repeated ANOVA and pariwise comparison was done using the LSD method. Measurement data with skewed distribution were represented as M(range). Count data were represented as absolute numbers, and comparison between groups was analyzed using the chi-suqare test. Results:(1) Intraoperative and postoperative situations:10 patients underwent successfully laparoscopic BPD-DS, including 1 patient undergoing concomitant cholecystectomy due to gallstone disease. There was no obvious hemorrhage, conversion to open surgery or perioperative death for the 10 patients. The operation time and duration of postoperative hospital stay were (256±28)minutes and 11 days(range, 4-38 days). Two patients had postoperative complications. (2) Follow-up: 10 patients were followed up for 6 months. During the follow-up, 3 patients had increased frequency of defecation, with 3-5 times per day, 7 patients had defecation frequency of 1-2 times per day. Of 10 patients, 4 cases had postoperative cholestasis, 2 cases development to gallstone, and the remaining 4 patients had no abnor-mality. The body weight, body mass index, waist circumference of 10 patients were (139±22)kg, (46±10)kg/m 2,(139±14)cm before operation, (107±19)kg, (35±8)kg/m 2, (118±17)cm at 3 months after operation, and (92±17)kg, (30±6)kg/m 2, (104±12)cm at 6 months after operation, showing significant differences ( F=170.01, 104.42, 120.25, P<0.05). The excess body mass reduc-tion rates at 3, 6 months after operation of 10 patients were 58%±36% and 81%±42%, showing a significant difference ( t=73.00, P<0.05). Of 10 patients, cases with type 2 diabetes, hypertriglyceri-demia, hypercholesteremia, elevated low density lipoprotein cholesterin level, hyperuricemia, hypertension were 5, 4, 6, 8, 9, 9 before operation, cases with complete remission were 4, 2, 5, 5, 1, 1 at 3 months after operation, and cases with complete remission were 5, 3, 4, 6, 7, 5 at 6 months after operation. Cases with partial remission of hypertension were 8 and 4 at 3, 6 months after operation. For 5 patients with type 2 diabetes, the fasting blood glucose and hemoglobin Alc were (11.4±3.1)mmol/L and 9.3%±1.6% before operation, (5.6±1.0)mmol/L and 5.5%±0.5% at 3 months after operation, (4.9±0.5)mmol/L and 4.8%±0.5% at 6 months after operation, showing significant differences ( F=14.55, 39.84, P<0.05). Of 10 patients, the retinal-binding protein, vitamins E, serum iron, serum zinc were normal before operation, cases with deficiency of above indicators were 5, 2, 1, 1 at 3 months after operation and 3, 3, 2, 4 at 6 months after operation. There was no clinical symptoms in patents with nutrient deficiency. Cases with deficiency of vitamins A, hypocalcemia, folic acid deficiency were 2, 2, 0 before operation, 5, 0, 0 at 3 months after operation and 3, 0, 1 at 6 months after operation. No deficiency of vitamins D, vitamins B12, ferritin or anemia occurred to the 10 patients. Conclusion:Laparoscopic BPD-DS is safe and effective for obesity.
