Laparoscopic subtotal cholecystectomy (LSC) has been a safe and viable alternative to conversion to laparotomy in cases of severe cholecystitis. The objective of this study is to determine the utility of intraoperative choledochoscopy in LSC for the exploration of the gallbladder, cyst duct, and subsequent stone clearance of the cystic duct in cases of severe cholecystitis. A total of 72 patients diagnosed with severe cholecystitis received choledochoscopy-assisted laparoscopic subtotal cholecystectomy (CALSC). A choledochoscopy was performed to explore the gallbladder cavity and/or cystic duct, and to extract stones using a range of techniques. The clinical records, including the operative records and outcomes, were subjected to analysis. No LSC was converted to open surgery, and no bile duct or vascular injuries were sustained. All stones within the cystic duct were removed by a combination of techniques, including high-frequency needle knife electrotomy, basket, and electrohydraulic lithotripsy. A follow-up examination revealed the absence of residual bile duct stones, with the exception of one common bile duct stone, which was extracted via endoscopic retrograde cholangiopancreatography. In certain special cases, CALSC may prove to be an efficacious treatment for the management of severe cholecystitis. This technique allows for optimal comprehension of the situation within the gallbladder cavity and cystic duct, facilitating the removal of stones from the cystic duct and reducing the residue of the non-functional gallbladder remnant.

The patient was a 55-year-old man who was admitted to hospital with "progressive myalgia and weakness for 4 months, and exacerbated for 1 month". Four months ago, he presented with persistent shoulder girdle myalgia and elevated creatine kinase (CK) at routine physical examination, which fluctuated from 1 271 to 2 963 U/L after discontinuation of statin treatment. Progressive myalgia and weakness worsened seriously to breath-holding and profuse sweating 1 month ago. The patient was post-operative for renal cancer, had previous diabetes mellitus and coronary artery disease medical history, had a stent implanted by percutaneous coronary intervention and was on long-term medication with aspirin, atorvastatin and metoprolol. Neurological examination showed pressure pain in the scapularis and pelvic girdle muscles, and V- grade muscle strength in the proximal extremities. Strongly positive of anti-HMGCR antibody was detected. Muscle magnetic resonance imaging (MRI) T2-weighted image and short time inversion recovery sequences (STIR) showed high signals in the right vastus lateralis and semimembranosus muscles. There was a small amount of myofibrillar degeneration and necrosis, CD4 positive inflammatory cells around the vessels and among myofibrils, MHC-Ⅰ infiltration, and multifocal lamellar deposition of C5b9 in non-necrotic myofibrils of the right quadriceps muscle pathological manifestation. According to the clinical manifestation, imageological change, increased CK, blood specific anti-HMGCR antibody and biopsy pathological immune-mediated evidence, the diagnosis of anti-HMGCR immune-mediated necrotizing myopathy was unequivocal. Methylprednisolone was administrated as 48 mg daily orally, and was reduced to medication discontinuation gradually. The patient's complaint of myalgia and breathlessness completely disappeared after 2 weeks, the weakness relief with no residual clinical symptoms 2 months later. Follow-up to date, there was no myalgia or weakness with slightly increasing CK rechecked. The case was a classical anti-HMGCR-IMNM without swallowing difficulties, joint symptoms, rash, lung symptoms, gastrointestinal symptoms, heart failure and Raynaud's phenomenon. The other clinical characters of the disease included CK as mean levels >10 times of upper limit of normal, active myogenic damage in electromyography, predominant edema and steatosis of gluteus and external rotator groups in T2WI and/or STIR at advanced disease phase except axial muscles. The symptoms may occasionally improve with discontinuation of statins, but glucocorticoids are usually required, and other treatments include a variety of immunosuppressive therapies such as methotrexate, rituximab and intravenous gammaglobulin.

Aim To investigate the protective effect of essential oil from Fructus Alpiniae Zerumbet (EOFAZ ) on type 2 diabetes-induced pancreatic injury in mice and its mechanism.Methods After C57 BL/6 mice fed with high-sugar and high-fat ( HFS) feed developed insulin resistance, streptozotocin ( STZ, 120 mg • kg 1 ) was injected intraperitoneal^ to establish type 2 diabetes model ( DM ) , then DM mice were randomly divided into: diabetes group ( DM ) , EOFAZ low-dose group (90 mg • kg 1 ) , EOFAZ high-dose group ( 180 mg • kg"1 ) , and metformin group (250 mg • kg 1 ).Healthy mice were randomly divided into : normal group and EOFAZ toxicity group ( 180 mg • kg"1).EOFAZ group and metformin group were given EOFAZ and metformin,while normal group and DM group were given an equal volume of normal saline once daily.After eight weeks of continuous intragastric administration, the mice were sacrificed, and the blood was collected to measure fasting blood glucose.HE staining was used to observe the pathological morphology of the pancreas; Western blot was used to analyze the expression of p62, Keleh-like epiehlorohvdrin-related protein 1 ( Keapl ), nuelear factor E2-related factor 2 ( Nrf2 ), and heme oxygenase- 1 ( HO-l ) , anti-apoptotic protein ( Bcl-2) and pro-apoptotic protein ( Bax).Immunohis- tochemistry was used to analyze the expression of Nr£2 in pancreatic tissue.Results Compared with DM group, after administration of EOFAZ , the pathological morphology of pancreas was significantly improved; Keapl , Bax protein expressions were significantly down-regulated and p62, Nrf2 , Ho-1 , Bcl-2 protein expressions were up-regulated ( P <0.05 ).Conclusions EOFAZ has a significant improvement effect on pancreatic injury induced by diabetes, and its effect may be related to the activation of p62/Keapl/Nrf2 to regulate apoptotic response.

Aim To explore the factors on behavior patterns of light/dark box(LDB)as an animal model of state anxiety in Kunming mice.Methods The behavior of adult,male,Kunming mice in LDB was recorded for five minutes,respectively.The following parameters were evaluated:percentage of time in the light area(Ltime%),percentage of squares crossing in the light area(Lcross%),percentage of rears in the light area(Lrear%),total number of squares crossing in the whole apparatus(Cross),total number of rears in the whole apparatus(Rear),total(Cross plus Rear),transitions between two areas(Transition),and number of fecal bolis in light box and dark box(Fbs).Subsequently,the factors,such as day-night rhythm,illumination area(L3/5 or L2/5 for ratio between Light box and Dark box:3:2 or 2:3,respectively),illumination color(in Dark box)and illumination intensity(in Light box),were investigated to screen the best experimental conditions.Results t-test showed that compared with night cycle,there was no significant difference in all LDB parameters during day cycle(P>0.05),while compared with 3/5 and 2/5,LDB parameters during day cycle such as Lcross%(t=5.363,P<0.01)in big area light box(L3/5),Lrear%(t=3.211,P<0.05)in small area light box(L2/5)increased statistically.The factorial design ANOVA showed that there was no significant difference in day-night rhythm on all LDB parameters(P>0.05),but a statistical influence of illumination area on Ltime%(F(1,20)=18.361,P<0.01),Lcross%(F(1,20)=49.148,P<0.01)and Lrear%(F(1,20)=8.424,P<0.01).The single factor ANOVA showed that there was significant influence of illumination color in dark box on Real(F(3,20)=3.746,P<0.05),Fbs(F(3,20)=3.585,P<0.05),and illumination intensity in light box on Cross(F(4,25)=2.569,P<0.05)and Total(F(4,25)=2.588,P<0.05).The Dunnett t test showed that compared with red color group,Rear(MD=-30.833,P<0.05)was significantly lower in yellow color group; while Cross(MD=-173.167,P<0.05)and Total(MD=-93.667,P<0.05)in 100 W group declined statistically compared with 15 W Group.Kruskal-Wallis test showed that there was no significant difference in illumination color and intensity on Fbs(P>0.05).Conclusions LDB as an animal model of state anxiety in Kunming mice can evaluate anxiety-,locomotion-exploration and emotionality- related behaviors,which cannot be affected by day-night rhythm,but illumination area(Ltime%,Lcross%,Lrear%),illumination color(Rear)and illumination intensity(Cross,Total).So it is recommended to adopt the uniform and fixed conditions,such as illumination area,color and intensity(less than 100 W).

Objective:To establish the normal values of water-perfused high resolution esophageal manometry (HREM)(GAP-36A) at resting period, water swallowing, semisolid swallowing and solid swallowing in Chinese population.Methods:From September 1, 2019 to June 30, 2020, 91 healthy volunteers receiving water-perfused HREM (GAP-36A) at resting period, water swallowing, semisolid swallowing and solid swallowing were selected from 9 hospitals (Union Hospital, Tongji Medical College, Huazhong University of Science and Technology; the First Affiliated Hospital of Dalian Medical University; the Second Hospital of Hebei Medical University; the Second Affiliated Hospital, Naval Medical University; the First Affiliated Hospital, Sun Yat-sen University; the First Affiliated Hospital, University of Science and Technology of China; Aviation General Hospital of China Medical University; the Affiliated Hospital of Medical School of Nanjing University and the First People′s Hospital of Yichang). Parameters included the position of the upper and lower edges of the upper esophageal sphincter (UES) and lower esophageal sphincter (LES), the length of the LES and UES, the position of the pressure inversion point (PIP), the resting pressure of UES and LES and swallow-related parameters such as the distal contraction integral (DCI), 4 s integrated relaxation pressure (IRP), distal latency (DL) and UES residual pressure. One-way analysis of variance, post-hoc test and sum rank test were used for statistical analysis.Results:A total of 87 healthy volunteers were enrolled, including 40 males and 47 females, aged (38.5±14.2) years old (ranged from 19 to 65 years old). The position of the upper and lower edges of the LES was (42.7±2.8) and (45.6±2.8) cm, respectively, the length of the LES was (2.9±0.4) cm, and the position of PIP was (43.3±2.8) cm. The position of the upper and lower edges of the UES was (18.1±3.0) and (22.6±2.0) cm, respectively, and the length of the UES was (4.8±1.0) cm. The resting pressure of LES and UES was (17.4±10.7) and (84.1±61.1) mmHg (1 mmHg=0.133 kPa), respectively. The DCI value at solid swallowing was higher than those at water swallowing and semisolid swallowing ((2 512.4±1 448.0) mmHg·s·cm vs. (2 183.2±1 441.2) and (2 150.8±1 244.8) mmHg·s·cm), and the differences were statistically significant ( t=-4.30 and -3.74, both P<0.001). The values of 4 s IRP at semisolid swallowing and solid swallowing were lower than that at water swallowing ((4.6±4.1) and (4.9±3.9) mmHg vs. (5.4±3.9) mmHg), and the differences were statistically significant ( t=3.38 and 2.09, P=0.001 and 0.037). The DL at water swallowing was shorter than those at semisolid swallowing and solid swallowing ((8.5±1.8) s vs. (9.8±2.2) and (10.6±2.8) s), and the DL at semisolid swallowing was shorter than that at solid swallowing, and the differences were statistically significant ( t=-10.21, -13.91 and -4.68, all P<0.001). The UES residual pressure at water swallowing was higher than those at semisolid swallowing and solid swallowing (9.5 mmHg, 6.5 to 12.3 mmHg vs. 8.0 mmHg, 4.5 to 11.7 mmHg and 5.5 mmHg, 2.0 to 9.3 mmHg), and the UES residual pressure at semisolid swallowing was higher than that at solid swallowing, and the differences were statistically significant ( t=3.48, 10.30 and 6.35, all P<0.001). Conclusions:The normal values of water-perfused HREM (GAP-36A) in Chinese population at resting period, water swallowing, semisolid swallowing and solid swallowing can provide a reference basis for clinical diagnosis and treatment for patients receiving water-perfused HREM examination.
