ObjectiveTo explore the clinical efficacy of Huanglian Jiedutang as an adjunctive treatment for acute cerebral infarction complicated with gastric motility disorder. MethodSixty patients with acute cerebral infarction complicated with gastric motility disorder with fire toxin syndrome were randomly divided into a western medicine control group （control group） and a traditional Chinese medicine （TCM） combined treatment group （observation group）， with 30 cases in each group. The control group received basic treatment for cerebral infarction and relevant western medical symptomatic treatment based on the patients' gastrointestinal symptoms. The observation group received Huanglian Jiedutang in addition to the treatment provided to the control group. The treatment course was 7 days. Neurological deficit scores and gastrointestinal dysfunction scores were assessed in both groups before treatment and on the 4th and 7th days of treatment. Gastrointestinal electrographic parameters， serum citrulline （CIT）， and motilin （MTL） levels were measured in both groups before treatment and on the 7th day of treatment. Clinical efficacy was compared between the two groups. ResultCompared with the baseline in both groups， the neurological deficit scores and gastrointestinal dysfunction scores were significantly reduced on the 4th and 7th days of treatment （P<0.05）. The reductions in these scores were more significant on the 7th day compared with those on the 4th day of treatment （P<0.05）. On the 4th and 7th days of treatment， the observation group showed a significantly greater reduction in neurological deficit scores and gastrointestinal dysfunction scores compared with the control group （P<0.05）. On the 7th day of treatment， compared with the baseline， both groups showed a significant increase in gastric antral and gastric body electric wave amplitudes as well as serum CIT and MTL levels （P<0.05）， and there were no statistically significant differences in the frequency of gastric antral and gastric body electric waves. On the 7th day of treatment， compared with the control group， the observation group had a significant increase in gastric antral and gastric body electric wave amplitudes as well as serum CIT and MTL levels （P<0.05）， and there were no statistically significant differences in the frequency of gastric antral and gastric body electric waves. After 7 days of treatment， the total effective rate in the observation group was 90.00% （27/30）， higher than 76.67% （23/30） in the control group， but the difference was not statistically significant. ConclusionAdjunctive treatment with Huanglian Jiedutang can effectively improve the symptoms of neurological function impairment and gastrointestinal dysfunction in patients with acute cerebral infarction complicated with gastric motility disorder， increase gastric antral and gastric body electric wave amplitudes， improve gastric motility disorder， and increase serum CIT and MTL levels， thereby improving the imbalanced secretion function of the gastrointestinal tract.

Objective:To analyze the association between HbA 1C variability and the incidence of diabetes retinopathy in patients with type 2 diabetes mellitus(T2DM). Methods:All the patients with type 2 diabetes receiving regular follow-up were enrolled from Lee′s Joint Clinic from 2002 to 2014. Demographic and laboratory data like HbA 1C were collected including fundal examination. According to HbA 1C variability, which was defined as the difference between baseline and last available HbA 1C, participants were divided into three groups, stable group with HbA 1C variability of ±10%, increase group(>10%), and decline group(<-10%). Results:A total of 3 657 T2DM participants were recruited including 662(13.4%) participants with diabetes retinopathy. Blood glucose gradually rose from ideal level [HbA 1C(7.04±1.35)%] and HbA 1C was up to (9.11±1.96)% at the end of follow-up in increase group. HbA 1C gradually fell to (7.27±1.12)% from (10.05±1.99)% of baseline in decline group. HbA 1C of the third group remained relatively stable. Adjusted for age, body mass index, systolic blood pressure, pulse pressure, duration of diabetes, mean HbA 1C of follow-up, glaucoma and so on, logistic regression revealed that participants in stable group( OR=0.800, 95% CI 0.645-0.992) and increase group( OR=0.706, 95% CI 0.548-0.909) had a lower risk of diabetes retinopathy than decline group( P<0.05). Conclusion:HbA 1C variability is an important risk factor of diabetes retinopathy in patients with T2DM. Patients with blood glucose declined had increased risk of diabetes retinopathy as compared to those with rising HbA 1C.

摘要
The correlation between transient receptor potential vanilloid-1 (TRPV1) receptor and peripheral nervous system diseases has been confirmed. In recent years, studies have shown that TRPV1 plays an important role in the central nervous system; its wide distribution in the hippocampus, cortex, and midbrain bridges the correlation between TRPV1 receptor and cognitive learning and memorial function. This paper reviews the biological role of TRPV1 receptor in the nervous system at home and abroad and concludes the relations of TRPV1 receptor with cognitive associated diseases, aiming at providing theory basis for whether TRPV1 receptors can be used as therapeutic drug targets for cognitive associated diseases.

Objective:To explore the diagnostic value of breast MRI in breast imaging reporting and data system (BI-RADS) 4 mammography-detected ultrasound-negative (MG+/US-) pure calcification lesions.Methods:The data of 51 patients (52 calcification lesions) who were diagnosed with BI-RADS 4 pure calcification by mammography, had no significant abnormality on ultrasonography, and finally obtained pathological results at Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from December 2013 to December 2019 were retrospectively analyzed. Of the 52 calcification lesions, 40 were benign and 12 were malignant. The mammographic findings (breast composition, calcification morphology, and distribution) and MR findings (enhancement pattern), of benign and malignant lesions were analyzed and compared with the histopathological results. The diagnostic performance of MRI was calculated.Results:There was a significant difference between benign and malignant calcification lesions in calcification morphology on mammography and enhancement pattern on MRI ( P<0.05). On breast MRI, malignant calcifications lesions showed mass or non-mass enhancement (12/12), while benign calcified lesions mostly showed no enhancement or punctate enhancement (27/40). The sensitivity, specificity, positive predictive value, and negative predictive value of breast MRI in the diagnosis of BI-RADS 4 MG+/US- pure calcification lesions were 66.7% (8/12), 75.0% (30/40), 44.4% (8/18) and 88.2% (30/34), respectively; The sensitivity, specificity, positive predictive value and negative predictive value for BI-RADS 4A calcifications were 66.7% (2/3), 74.2% (23/31), 20.0% (2/10) and 95.8% (23/24), respectively. The sensitivity, specificity, positive predictive value and negative predictive value for BI-RADS 4B calcifications were 66.7% (4/6), 85.7%(6/7),80.0% (4/5) and 75.0% (6/8), respectively. Conclusions:MRI has a high differential diagnostic value for mammographic BI-RADS 4 pure calcifications with ultrasound-negative, especially for BI-RADS 4A calcifications. Follow-up instead of biopsy is recommended for lesions with no enhancement or punctate enhancement on MRI.

摘要
To evaluate immune efficacy of the recombinant Lactobacillus casei, we constructed pLA-Newcastle disease virus (NDV)-F/L. casei and obtained the expression products. PCR amplified the NDV F gene carrying part of the major epitopes. The target gene was inserted to the shuttle plasmid pLA, and then transformed into Escherichia coli BL21 (DE3) in order to screen positive recombinant plasmid. The positive recombinant plasmid was transformed into L. casei by electroporation to construct pLA-NDV-F/L. casei. The positive strains were identified by PCR. The reactivity of the recombinant bacteria was identified by Western blotting and the protein expression was detected by indirect immunofluorescence, flow cytometry and laser confocal microscopy. The 14-day-old chickens in each group were vaccinated by oral plus nose drops. The pLA-NDV-F/L. casei twice immunization group and three times immunization group, the commercial vaccine group, the pLA/L. casei group, the unchallenge PBS and the challenge PBS group were established. IgG in serum and sIgA in the lavage fluid of intestinal, nasal and lung were detected by ELISA. The protection rate of chickens was evaluated. The results showed that 94.10% of the recombinant bacteria expressed the F protein. The recombinant protein was highly expressed on the surface of L. casei with a protein size of 62 kDa, which specifically bound to anti-NDV serum. The levels of anti-F IgG and sIgA antibodies in each test group were significantly higher than those in the control groups. The duration of antibody in the pLA-NDV-F/L. casei three-time immunization group lasted 28 days longer than that in the twice immunized group, and there was no significant difference between antibody peak values. The attack protection rates in each group of immunized pLA-NDV-F/L. casei three times, twice, attenuated vaccine, pLA/L. casei and PBS were 80%, 80%, 90%, 0% and 0%, respectively. Therefore, the antigenic protein of NDV F was successfully expressed by L. casei expression system, which has of reactogenicity and immunogenicity, and could induce protective immune responses in chickens.

Postcholecystectomy syndrome (PCS) is a common syndrome with complex etiologies after laparoscopic cholecystectomy, rather than a specific disease. In addition to bile duct stones, bile duct injury, and sphincter of Oddi dysfunction, PCS is also associated with the abnormalities in bile acid pool, farnesoid X receptor, and GPBAR1/TGR5 pathways after surgery, reductions in fibroblast growth factor 19 and surfactant protein D, changes in gastrointestinal hormones such as motilin and cholecystokinin, and disappearance of various physiological reflexes and nerve reflexes involving the gallbladder. All these changes in physiological function can induce PCS. As the number of patients undergoing laparoscopic cholecystectomy is increasing year by year, the incidence rate of PCS is also increasing. This article briefly summarizes the etiology, pathophysiology, diagnosis, treatment, and prevention of PCS.

Objective@#To explore the relationship between overnight urinary sodium to potassium ratio and the risk of cardiovascular disease (CVD).@*Methods@#A subsample of 10 percent of the participants (35-59 years old) from the People's Republic of China-United States Collaborative Study of Cardiovascular and Cardiopulmonary Epidemiology (prospective survey) were used. Three consecutive overnight urine samples were collected in the autumn of 1983-1984 and the spring in 1985-1986, respectively. Urinary sodium and potassium were detected and calculated for 8 hours excretion. The occurrences of cardiovascular events were recorded in 2 years interval from 1987-1988 until December 31, 2005. Participants were divided into first ratio group, second ratio group, and third ratio group based on the tertiles of sodium to potassium ratio. Cox proportional hazard regression model was used to determine the relationship between sodium to potassium ratio and risk of CVD. In addition, participants were divided into 2 subgroups by the median of overnight urinary sodium and potassium, and then combined each other for 4 subgroups including low sodium-low potassium group, low sodium-high potassium group, high sodium-low potassium group, and high sodium-high potassium group, to explore the relationship between different sodium-potassium combinations and the risk of CVD.@*Results@#A total of 954 participants were included in the final analysis, of whom 459 (48.1%) were males. There were 318 cases in the first, second and third ratio group, respectively. There were 347 cases in low sodium-low potassium group and high sodium-high potassium group, and 130 cases in low sodium-high potassium group and high sodium-low potassium group. After a median follow-up of 18.6 (18.3, 19.3) years, cardiovascular events occurred in 81 participants, including 64 stroke and 20 coronary heart disease events. Multivariate analysis showed that comparing with the first ratio group, the hazard ratios (HR) in the second and the third ratio groups were 2.04 (95%CI 1.06-3.95, P=0.034) and 2.07 (95%CI 1.07-4.03, P=0.032), respectively. The CVD risk in low sodium-low potassium group was 24% higher than the low sodium-high potassium group (reference), but this result did not reach statistical significant level (P=0.685). The risks in high sodium-high potassium group (HR=3.32, 95%CI 1.26-8.76,P=0.015) and high sodium-low potassium (HR=3.04, 95%CI 1.05-8.83, P=0.041) group were both significantly increased.@*Conclusions@#Overnight urinary sodium to potassium ratio is positively correlated with the risk of cardiovascular events. High urinary sodium plays a more important role for the increased risk of cardiovascular events than low potassium.

OBJECTIVE@#To explore the prognostic factors of patients with unresectable liver metastasis colorectal cancer after failed conversion chemotherapy.@*METHODS@#A retrospective, case-controlled study was performed. Study subjects were 105 patients who were diagnosed with synchronous liver metastasis colorectal cancer after failed chemotherapy (metastasis evaluated as unresectable after the conversion chemotherapy) at Xinhua Hospital, Shanghai Jiaotong University from January 2012 to December 2015. Overall survival(OS) was retrospectively analyzed using Kaplan-Meier method. Log-rank test was used to compare survival among groups. Univariate and multivariate analysis was conducted for prognosis using Cox regression model.@*RESULTS@#Of 105 cases,70 were male and 35 were female with median age of 60 years old. Twenty-one patients had right colon cancer, 41 had left colon cancer, 42 had rectal cancer and 1 had synchronous cancers(sigmoid colon and rectum). One hundred and two (97.1%) patients were cT3-4 and 90 patients were cN+ (imaging diagnosis). Eighty-nine (84.8%) patients were loaded with 2 or more liver metastases with the median maximum diameter of 48.3 mm. The patients were followed up for 3 to 43 months from the day of diagnosis. The median OS was 11 months (interquartile range, 8-18). The median OS of patients with cN0, cN1 and cN2 stage was 17, 13 and 10 months, respectively(P=0.026). The median OS of patients with single lesion, 2-3 lesions, 4-10 lesions and more than 10 lesions was 15, 15, 17 and 9 months, respectively (P=0.002). OS of patients with maximum diameter of liver metastatic lesion ≤ 50 mm, 51-100 mm and >100 mm was 15, 10 and 8 months, respectively(P=0.003). The median OS of patients with chemotherapy response of partial response (PR), stable disease (SD) and progressive disease (PD) was 17, 14 and 8 months, respectively(P<0.001). OS was 17 months in patients receiving second line chemotherapy and was 10 months in those without second line chemotherapy (P<0.001). OS in patients undergoing primary tumor resection was 13 month and in those without primary tumor resection was 9 months; the difference was not significant (P=0.060). Multivariate analysis showed that cN2(HR=2.115, 95%CI:1.089-4.109, P=0.027), the maximum diameter of liver metastatic lesion more than 100 mm (HR=3.112, 95%CI:1.455-6.657, P=0.003), chemotherapy response of PD (HR=4.435, 95%CI:2.506-7.533,P<0.001) and without second line chemotherapy(HR=4.432,95%CI:2.186-8.986, P=0.010) were independent prognostic factors.@*CONCLUSIONS@#For patients with unresectable liver metastasis from colorectal cancer after failed conversion chemotherapy, prognostic factors include cN2, the maximum diameter of liver metastatic lesion, chemotherapy response and second line chemotherapy. Whether the resection of primary tumor can prolong OS further study.

Objective: To evaluate the applications and problems of statistical methods for articles published in《Chinese Circulation Journal》. Methods: We reviewed the statistical methods for original articles published in《Chinese Circulation Journal》in 2010, 2011 and 2015; general status with problems was analyzed and the situations were compared among different years. Results: A total of 404 articles were enrolled, statistical hypothesis testing was performed in 366 of them, 32 had descriptive statistics only and 6 articles were meta-analysis. The most frequently used statistical methods were student'st-test (57.4%), followed by chi-squared analysis (56.7%), analysis of variance (35.2%) and regression analysis (23.0%). The main statistical problems in Methods included in described method un-matched to really used method and insufifcient or wrong description. The proportion of insufifcient or wrong description in 2010 and 2011 was 36.6% (71/194), while in 2015 was 26.2% (55/210),P=0.02. The major wrong application of statistical approach was ignoring design with improper method and using unsatisifed precondition for speciifc analysis. The proportion of improper statistical method application in 2010 and 2011 was 19.1% (33/173), in 2015 was 19.7% (38/193),P=0.88. Conclusion: The quality of statistics was improved in 2015 than 2010 and 2011 for articles published in《Chinese Circulation Journal》; while there were still problems at certain degree, enhanced statistical review should be conducted in medical journals.

Objective To investigate the relationship between vitamin D level in plasma and concomitant symptoms in children over 4 years of age. Methods Radioimmunoassay was employed to detect the vitamin D level in plasma of 98 children over 4 years of age suffering from monoarticular joint-pain, debility, dizziness and hyperhidrosis. Results Among the 98 cases, 15 cases (rickets) were found to have a vitamin D level of 0-10ng/ml, 26 cases (subclinic rickets) with a level of 10.1-15ng/ml, 55 cases with a level of 15.1-60ng/ml, and the remaining 2 were found to have a level of 61-86ng/ml. A significant positive correlation existed between the low vitamin D level in plasma and the symptoms of joint-pain, debility, dizziness, and hyperhidrosis. Conclusion It is of a diagnostic significance to determine the 25-hydroxyvitanmin D_3 level in plasma to confirm the diagnosis of delayed vitamin D deficiency rickets in children.
