A Grading System for Assessing the Status of the Sphincter of Oddi During Intraoperative Choledochoscopy: A Surgeon's Perspective.

BACKGROUND: The aim of this study was to establish a simple and practical grading system for evaluating the status of the sphincter of Oddi (SO) during intraoperative choledochoscopy. This system helps identify relevant variables that influence the status of the SO and provides recommendations for preventing stone recurrence. METHODS: Ninety-three patients were selected retrospectively from a total of 316 patients diagnosed with choledocholithiasis between July 2020 and June 2023. All patients underwent common bile duct (CBD) exploration surgery and intraoperative choledochoscopy. The status of the SO was assessed during choledochoscopy. According to the severity of the condition, the patients were categorized into 4 groups. Data from each group, grades 1, 2, 3, 4, was analyzed statistically. RESULTS: The number of patients in grade 1 was significantly lower than that of the other 3 groups. Except for grade 1, patients in grade 4 exhibited significant differences compared with the other 2 groups in terms of the diameter of the CBD, size of stones, presence of pneumobilia, and history of endoscopic retrograde cholangiopancreatography (ERCP) (P<0.05). There were no significant differences between the groups in terms of sex, age, liver function, number of stones, history of gastrectomy, cholecystectomy, or CBD exploration. CONCLUSIONS: The grading system helps us classify different sphincter functions and better understand the formation of choledocholithiasis by subdividing the status of the SO. Endoscopic sphincterotomy (EST) treatment can easily result in the loss of SO function, which increases the risk of stone recurrence.

Surgical Treatment of Brucellar Cervical Epidural Abscess.

OBJECTIVES: Brucellar cervical epidural abscess (CEA) is a rare condition with potentially permanent neurological damage if left untreated. This study aims to define the clinical presentation of brucellar CEA and evaluate the outcome of surgical treatment, specifically decompression and fusion surgery. The findings will contribute to understanding whether all patients with brucellar CEA could benefit from this surgical intervention. METHODS: A retrospective study on brucellar spondylitis was conducted at the First Hospital of Jilin University from August 2018 to August 2022. During this period, a total of 37 patients were diagnosed with brucellar spondylitis at the hospital. Out of the 37 cases, six patients (16.2%) were confirmed to have CEA through cervical magnetic resonance imaging examination and serology test results.. RESULTS: Six patients were diagnosed with brucellar CEA (16.2%), of whom 5 successfully underwent anterior cervical decompression and fusion surgery. One patient had a large prevertebral abscess that could only be drained. In combination with effective antibiotic therapy, the clinical performance of the 5 patients who underwent surgery improved after the surgery. The remaining one patient required delayed surgery due to instability of the cervical spine. The follow-up period of all the 6 patients was 6 months. CONCLUSIONS: Brucellosis should be considered as a potential cause of CEA, especially in endemic areas. Timely detection and effective management of this condition are crucial in order to minimize the associated morbidity and mortality. For patients with detectable brucellar CEA, we recommend decompression and fusion surgery.

ObjectiveTo explore the effect of Buzhong Yiqitang on the immune imbalance of helper T cell 17 （Th17）/regulatory T cell （Treg） and Notch1 signaling pathway in mice with autoimmune thyroiditis （AIT）. MethodA total of 60 8-week-old NOD.H-2h4 mice were randomly divided into the normal group， model group， western medicine group （selenium yeast tablet， 32.5 mg·kg-1）， and low-dose （4.78 g·kg-1·d-1）， middle-dose （9.56 g·kg-1·d-1）， and high-dose （19 g·kg-1·d-1） Buzhong Yiqitang groups， with 10 mice in each group. The normal group was fed with distilled water， and the other groups were fed with water containing 0.05% sodium iodide for eight weeks. After the animal model of AIT was formed spontaneously， the mice were killed under anesthesia after intragastric administration for eight weeks. Serum anti-thyroglobulin antibodies （TGAb）， thyroid-stimulating hormone （TSH）， free triiodothyronine （FT3）， and free thyroid hormone （FT4） were detected by enzyme-linked immunosorbent assay （ELISA）， and thyroid tissue changes were observed by hematoxylin-eosin （HE） staining. The mRNA and protein expressions of retinoid-related orphan receptor-γt （RORγt）， interleukin （IL）-17， forkhead box P3 （FoxP3）， IL-10， Notch1， and hair division-related enhancer 1 （Hes1） in thyroid tissue were detected by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot， respectively. ResultCompared with the normal group， the thyroid structure of the model group was severely damaged， and lymphocytes were infiltrated obviously. The levels of serum TGAb， FT3， and FT4 contents were significantly increased， and TSH content was significantly decreased （P<0.01）. The mRNA and protein expression levels of RORγt， IL-17， Notch1， and Hes1 were significantly increased， while those of FoxP3 and IL10 were significantly decreased in the model group （P<0.01）. Compared with the model group， thyroid structural damage and lymphocyte infiltration were improved in the treatment groups， and serum TGAb， FT3， and FT4 contents were significantly decreased. TSH content was increased， and mRNA and protein expression levels of RORγt， IL-17， Notch1， and Hes1 were decreased. mRNA and protein expression levels of FoxP3 and IL-10 were increased to different degrees （P<0.05， P<0.01）， and the middle-dose Buzhong Yiqitang group had the most significant intervention effect. ConclusionBuzhong Yiqitang can alleviate the thyroid structural damage in AIT mice， and its mechanism may be related to improving the abnormal differentiation of Th17/Treg immune cells and inhibiting the activation of the Notch1 signaling pathway.

Expert Consensus on Clinical Diseases Responding Specifically to Traditional Chinese Medicine： Threatened Abortion / 中国实验方剂学杂志

Threatened abortion is a common disease of obstetrics and gynecology and one of the diseases responding specifically to traditional Chinese medicine （TCM）. The China Association of Chinese Medicine organized experts in TCM obstetrics and gynecology， Western medicine obstetrics and gynecology， and pharmacology to deeply discuss the advantages of TCM and integrated Chinese and Western medicine treatment as well as the medication plans for threatened abortion. After discussion， the experts concluded that chromosome， endocrine， and immune abnormalities were the key factors for the occurrence of threatened abortion， and the Qi and blood disorders in thoroughfare and conception vessels were the core pathogenesis. In the treatment of threatened abortion， TCM has advantages in preventing miscarriages， alleviating clinical symptoms and TCM syndromes， relieving anxiety， regulating reproductive endocrine and immune abnormalities， personalized and diversified treatment， enhancing efficiency and reducing toxicity， and preventing the disease before occurrence. The difficulty in diagnosis and treatment of threatened abortion with traditional Chinese and Western medicine lies in identifying the predictors of abortion caused by maternal factors and the treatment of thrombophilia. Recurrent abortion is the breakthrough point of treatment with integrated traditional Chinese and Western medicine. It is urgent to carry out high-quality evidence-based medicine research in the future to improve the modern diagnosis and treatment of threatened abortion with TCM.

OBJECTIVE@#To investigate the effectiveness of Flow-through bridge anterolateral thigh flap transplantation in the treatment of complex calf soft tissue defects.@*METHODS@#The clinical data of the patients with complicated calf soft tissue defects, who were treated with Flow-through bridge anterolateral thigh flap (study group, 23 cases) or bridge anterolateral thigh flap (control group, 23 cases) between January 2008 and January 2022, were retrospectively analyzed. All complex calf soft tissue defects in the two groups were caused by trauma or osteomyelitis, and there was only one major blood vessel in the calf or no blood vessel anastomosed with the grafted skin flap. There was no significant difference between the two groups in general data such as gender, age, etiology, size of leg soft tissue defect, and time from injury to operation ( P>0.05). The lower extremity functional scale (LEFS) was used to evaluate the sufferred lower extremity function of the both groups after operation, and the peripheral blood circulation score of the healthy side was evaluated according to the Chinese Medical Association Hand Surgery Society's functional evaluation standard for replantation of amputated limbs. Weber's quantitative method was used to detect static 2-point discrimination (S2PD) to evaluate peripheral sensation of the healthy side, and the popliteal artery flow velocity, toenail capillary filling time, foot temperature, toe blood oxygen saturation of the healthy side, and the incidence of complications were compared between the two groups.@*RESULTS@#No vascular or nerve injury occurred during operation. All flaps survived, and 1 case of partial flap necrosis occurred in both groups, which healed after free skin grafting. All patients were followed up 6 months to 8 years, with a median time of 26 months. The function of the sufferred limb of the two groups recovered satisfactorily, the blood supply of the flap was good, the texture was soft, and the appearance was fair. The incision in the donor site healed well with a linear scar, and the color of the skin graft area was similar. Only a rectangular scar could be seen in the skin donor area where have a satisfactory appearance. The blood supply of the distal limb of the healthy limb was good, and there was no obvious abnormality in color and skin temperature, and the blood supply of the limb was normal during activity. The popliteal artery flow velocity in the study group was significantly faster than that in the control group at 1 month after the pedicle was cut, and the foot temperature, toe blood oxygen saturation, S2PD, toenail capillary filling time, and peripheral blood circulation score were significantly better than those in the control group ( P<0.05). There were 8 cases of cold feet and 2 cases of numbness on the healthy side in the control group, while only 3 cases of cold feet occurred in the study group. The incidence of complications in the study group (13.04%) was significantly lower than that in the control group (43.47%) ( χ 2=3.860, P=0.049). There was no significant difference in LEFS score between the two groups at 6 months after operation ( P>0.05).@*CONCLUSION@#Flow-through bridge anterolateral thigh flap can reduce postoperative complications of healthy feet and reduce the impact of surgery on blood supply and sensation of healthy feet. It is an effective method for repairing complex calf soft tissue defects.

Exogenous pancreatic kininogenase protects against tacrolimus-induced renal injury by inhibiting PI3K/AKT signaling: The role of bradykinin receptors.

BACKGROUND: Tissue kallikrein offers a wide spectrum of biological activity in the protection against various types of injury. However, information on its role in tacrolimus (TAC)-induced renal injury is limited. OBJECTIVES: This study aimed to assess the beneficial effects of pancreatic kininogenase (PK) in a rat model of chronic TAC nephrotoxicity and in vitro. METHODS: Sprague Dawley rats were treated daily with either TAC or PK or a combination of the two for four weeks. The influence of PK on renal injury was examined in terms of renal function, histopathology, cytokine expression, oxidative stress, intracellular organelles, programmed cell death, and PI3K/AKT signaling. Human kidney proximal tubular (HK-2) cells and mouse mesangial (SV40 MES13) cells treated with TAC and PK were also studied. RESULTS: PK treatment improved renal function and histopathology. This effect was paralleled by downregulation of proinflammatory and profibrotic cytokine expression. TAC-induced oxidative stress was closely associated with endoplasmic reticulum stress and mitochondrial dysfunction, resulting in excessive programmed cell death (apoptosis and autophagy) that was significantly abrogated by concurrent PK interference with PI3K/AKT signaling. PK also stimulated bradykinin receptor 1 (B1R) and B2R mRNA synthesis and increased bioactive nitric oxide (NO) and cAMP concentrations in TAC-treated kidneys. Blockade of either B1R or B2R eliminated the renoprotective effects of PK. In HK-2 and SV40 MES13 cells, PK decreased TAC-induced overproduction of intracellular reactive oxygen species and inhibited apoptotic cells, whereas cell viability was improved. Moreover, activated PI3K/AKT signaling in HK-2 cells was inhibited by PK and the PI3K inhibitor, LY294002. CONCLUSIONS: These findings indicate that PK treatment protects against chronic TAC nephrotoxicity via inhibition of PI3K/AKT signaling.

Repair of complex soft tissue defect in calf by ALTF with a cross-limb bridged "Y" shape vascular anastomosis: a report of 33 cases / 中华显微外科杂志

Objective:To explore the clinical effect of ALTF transfer with cross-limb bridged "Y" shape vascular anastomosis in repair of complex soft tissue defects in calf.Methods:From August 2010 to September 2020, 33 patients(23 males and 10 females) with complex traumatic soft tissue defects in calf were treated. Preoperative angiography and intraoperative exploration confirmed that there was only 1 main vessel remained in the affected calf or the wound surface and the vessel could not be anastomosed with the vascular pedicle of the ALTF. The size of flap were 16 cm × 8 cm to 25 cm × 18 cm. Two patients received bilobed ALTFs. A "Y" shape anastomosis between the artery of ALTF vascular pedicle and the posterior tibial artery of the contralateral lower limbs was made in all 33 patients to establish the blood supply to the transferred free ALTF. The "Y" shape cross-limb bridged blood vessels at the proximal end of the vascular pedicle artery of the flap were embedded at both ends of the cut-off superior ankle posterior tibial artery of the contralateral lower limb. The vein of the flap was anastomosed with the saphenous vein that associates with the posterior tibial artery. The surface of the suspended blood vessel "bridge" was wrapped with a free skin craft, and the lower limbs were fixed in a straight and parallel position with an external fixation frame. The perfused area of the flap was directly sutured or covered with a free skin craft. The vascular bridge was kept for 3 to 6 weeks before being separated. Outpatient follow-up after discharge.Results:All the patients were entered the postoperative follow-up was 13 months to 7 years, in an average of 25 months. Among the 33 flaps, 31 survived completely, except 1 had necrosis and the other 1 had partial necrosis at the distal end of the flap. The flaps received good blood supply, hence with soft texture and satisfactory appearance. Doppler or DSA was performed after the surgery on the posterior tibial artery of the healthy limb, and the vascular pulsation and patency were found normal. Donor sites for the free skin graft healed well.Conclusion:The ALTF transfer with cross-limb bridged "Y" vascular anastomosis is one of the effective techniques and it was employed in the repair of complex defects of calf soft tissue. It solved the tissue that there was only 1 main vessel or even without a suitable vessel could be anastomosed with the pedicle of the flap.

Effect and Safety of Kangfuyan Capsules () for Relieving Chronic Pelvic Pain: A Multicenter, Randomized, Controlled, Double-Blind, Parallel-Group Clinical Trial / 中国结合医学杂志

OBJECTIVE@#To evaluate the effect and safety of Kangfuyan Capsules () for treating pelvic inflammatory disease (PID) in patients with chronic pelvic pain (CPP) in a multicenter, randomized, controlled, double-blind, parallel-group clinical trial.@*METHODS@#Totally, 240 PID patients with CPP were randomized into 2 groups using a computer generated random number at a 1:1 ratio from 10 hospitals in China between September 2014 and November 2015. Patients received either oral Kangfuyan Capsules or Gongyanping Capsules (, control); the regimen for both groups comprised 4 capsules (3 times daily) for 12 weeks, with follow-up visit 4 weeks after treatment. The visual analogue scale (VAS) scores, clinical responses, remarkable cure rates for each symptom, and quality of life scores were assessed at baseline, and after 1, 2, and 3 months. Adverse events were also recorded.@*RESULTS@#The VAS scores were significantly lower (P<0.05), whereas the clinical responses, remarkable cure rates for lower abdominal pain, uterine tenderness, adnexal mass, and adnexal tenderness, and Health-related quality of life (EQ-5D) scores were higher in the Kangfuyan group than in the control group at 3 months (P<0.05). Common treatment-related adverse events included high hepatic enzyme levels, reduced hemoglobin levels, and elevated platelet counts, although all the adverse events were either mild or moderate in severity.@*CONCLUSION@#Compared with Gongyanping therapy, Kangfuyan therapy yielded markedly better analgesia effects for CPP caused by PID, with obvious long-term efficacy and good safety.

L-carnitine treatment attenuates renal tubulointerstitial fibrosis induced by unilateral ureteral obstruction

Background/Aims@#Accumulating evidence indicates that L-carnitine (LC) protects against multiorgan damage through its antioxidant properties and preservation of the mitochondria. Little information is available about the effects of LC on renal fibrosis. This study examined whether LC treatment would provide renoprotection in a rat model of unilateral ureteral obstruction (UUO) and in vitro. @*Methods@#Sprague-Dawley rats that underwent UUO were treated daily with LC for 7 or 14 days. The influence of LC on renal injury caused by UUO was evaluated by histopathology, and analysis of gene expression, oxidative stress, mitochondrial function, programmed cell death, and phosphatidylinositol 3-kinase (PI3K)/ AKT/forkhead box protein O 1a (FoxO1a) signaling. In addition, H2O2-exposed human kidney cells (HK-2) were treated with LC. @*Results@#LC treatment inhibited expression of proinflammatory and profibrotic cytokines, and was followed by a significant attenuation of tubulointerstitial inflammation and fibrosis. The increased oxidative stress caused by UUO was associated with mitochondrial dysfunction and excessive apoptosis and autophagy via PI3K/AKT/FoxO1a-dependent signaling, and this was abrogated by administration of LC. In H2O2-exposed HK-2 cells, LC decreased intracellular production of reactive oxygen species, and suppressed expression of profibrotic cytokines and reduced the number of apoptotic cells. @*Conclusions@#LC protects against the progression of tubulointerstitial fibrosis in an obstructed kidney.

Nicotine exacerbates tacrolimus-induced renal injury by programmed cell death

Background/Aims@#Cigarette smoking is an important modifiable risk factor in kidney disease progression. However, the underlying mechanisms for this are lacking. This study aimed to assess whether nicotine (NIC), a major toxic component of cigarette smoking, would exacerbates tacrolimus (TAC)-induced renal injury. @*Methods@#Sprague-Dawley rats were treated daily with NIC, TAC, or both drugs for 4 weeks. The influence of NIC on TAC-caused renal injury was examined via renal function, histopathology, oxidative stress, mitochondria, endoplasmic reticulum (ER) stress, and programmed cell death (apoptosis and autophagy). @*Results@#Both NIC and TAC significantly impaired renal function and histopathology, while combined NIC and TAC treatment aggravated these parameters beyond the effects of either alone. Increased oxidative stress, ER stress, mitochondrial dysfunction, proinf lammatory and profibrotic cytokine expressions, and programmed cell death from either NIC or TAC were also aggravated by the two combined. @*Conclusions@#Our observations suggest that NIC exacerbates chronic TAC nephrotoxicity, implying that smoking cessation may be beneficial for transplant smokers taking TAC.

Application of "mastery learning" in medical education / 中华医学教育探索杂志

Mastery learning is a competency-based mixed education method, which divides complex medical education contents into several teaching units according to the degree of difficulty and sets minimum passing standard for each teaching unit. Formative assessment was used to evaluate whether the learners had reached the mastery standard and finally mastered the knowledge through pass-continue or fail-repeat approach. The learners who had reached the mastery standard were usually able to use their knowledge more freely in clinical practice, and were able to accomplish more complex tasks through their own judgment with less supervision.

Efficacy and safety of Shexiang Baoxin pill (MUSKARDIA) in patients with stable coronary artery disease: a multicenter, double-blind, placebo-controlled phase IV randomized clinical trial / 中华医学杂志(英文版)

BACKGROUND@#The Shexiang Baoxin Pill (MUSKARDIA) has been used for treating coronary artery disease (CAD) and angina for more than 30 years in China. Nevertheless, methodologically sound trials on the use of MUSKARDIA in CAD patients are scarce. The aim of the study is to determine the effects of MUSKARDIA as an add-on to optimal medical therapy (OMT) in patients with stable CAD.@*METHODS@#A total of 2674 participants with stable CAD from 97 hospitals in China were randomized 1:1 to a MUSKARDIA or placebo group for 24 months. Both groups received OMT according to local tertiary hospital protocols. The primary outcome was the occurrence of a major adverse cardiovascular event (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction (MI), or non-fatal stroke. Secondary outcomes included all-cause mortality, non-fatal MI, non-fatal stroke, hospitalization for unstable angina or heart failure, peripheral revascularization, angina stability and angina frequency.@*RESULTS@#In all, 99.7% of the patients were treated with aspirin and 93.0% with statin. After 2 years of treatment, the occurrence of MACEs was reduced by 26.9% in the MUSKARDIA group (MUSKARDIA: 1.9% vs. placebo: 2.6%; odds ratio = 0.80; 95% confidence interval: 0.45-1.07; P  = 0.2869). Angina frequency was significantly reduced in the MUSKARDIA group at 18 months (P = 0.0362). Other secondary endpoints were similar between the two groups. The rates of adverse events were also similar between the two groups (MUSKARDIA: 17.7% vs. placebo: 17.4%, P = 0.8785).@*CONCLUSIONS@#As an add-on to OMT, MUSKARDIA is safe and significantly reduces angina frequency in patients with stable CAD. Moreover, the use of MUSKARDIA is associated with a trend toward reduced MACEs in patients with stable CAD. The results suggest that MUSKARDIA can be used to manage patients with CAD.@*TRIAL REGISTRATION@#chictr.org.cn, No. ChiCTR-TRC-12003513.

Shen-Kang protects against tacrolimus-induced renal injury

BACKGROUND/AIMS@#Evidence suggests that Shen-Kang (SK), a traditional Chinese herbal medicine, protects against various types of renal injury. In this study, we evaluated whether SK treatment confers renoprotection in a rat model of chronic tacrolimus (TAC) nephropathy.@*METHODS@#Rats were treated daily with TAC (1.5mg/kg, subcutaneously) and SK (450 mg/kg, intravenously) for 4 weeks. The effects of SK on TAC-induced renal injury were assessed by measuring renal function, urine albumin excretion, histopathology, inflammatory cell infiltration, expression of profibrotic (transforming growth factor β1 [TGF-β1] and TGF-β inducible gene-h3 [βig-h3]) and proinflammatory cytokines, oxidative stress, and apoptotic cell death.@*RESULTS@#Administration of SK preserved glomerular integrity (fractional mesangial area and Wilms tumor 1-positive glomeruli), attenuated tubulointerstitial fibrosis, and reduced the number of ectodermal dysplasia 1-positive cells, and this was paralleled by improved urine albumin excretion and renal dysfunction. At the molecular level, SK treatment suppressed expression of TGF-β1/Smad2/3, βig-h3, and proinflammatory cytokines. Oxidative stress and apoptotic cell death were significantly decreased with SK treatment, and apoptosis-related genes were regulated toward cell survival (active caspase-3 and the B-cell lymphoma-2/Bcl2-associated X [Bcl-2/Bax] ratio).@*CONCLUSIONS@#SK protects against TAC-induced renal injury.

miRNA-99b inhibits the invasion ability of glioma cells by targeting mTOR / 中国药理学通报

Aim To detect the expression of miRNA-99b and mTOR in glioma tissues and to investigate the effect of miRNA-99b on the cell invasion ability of hu-man glioma cell line U251. Methods The expres-sions of miRNA-99b and mTOR mRNA in glioma tis-sues and normal brain tissues were detected by real-time PCR. After co-transfection with miRNA-99b mim-ics and wild or mutation type mTOR 3′UTR recombina-tion vector,the specific binding ability of miRNA-99b to 3′-UTR in mTOR gene was examined by luciferase gene reporter system. The expression levels of miRNA-99b,mTOR mRNA and mTOR protein in glioma cell line U251 after transfected with miRNA-99b mimics were measured by real-time PCR and Western blot,re-spectively. The cell invasion was measured by Tran-swell assay. The changes of mTOR and miRNA-99b expression levels in U251 cells after transfection with mTOR PsiCHECK were detected by real-time PCR. The correlation between the expression of miRNA-99b and prognosis was analyzed statistically. Results The expressed level of miRNA-99b was lower, and the ex-pression level of mTOR was higher in the glioma tissues than that in the normal brain tissues. The expression of miRNA-99b was up-regulated, and the expressions of mTOR mRNA and protein were down-regulated in U251 cells after transfection with miRNA-99b mimics. However, the abilities of invasion of U251 cells after transfection with miRNA-99b mimics were inhibited. The relative protein expression levels of mTOR in mTOR PsiCHECK group were significantly different from those in negative control group, but the relative expression levels of miRNA-99b had no signifi-cant difference compared with those in negative control group. Over-expression of mTOR restored the abilities of cell invasion in U251 cells, which was reduced by miRNA-99b. The Kaplan—Meier analysis and Log-Rank Test showed that there were significant differ-ences in overall survival (OS) between the miRNA-99b high-expression and low-expression group. Con-clusions The expression level of miRNA-99b is low in human glioma tissue. miRNA-99b may inhibit the cell invasion activity of glioma cell line U251 in vitro via inhibiting mTOR expression.
