ABSTRACT

Objective:To establish and evaluate a nomogram for long-term survival of patients with intrahepatic cholangiocarcinoma (ICC) after radical resection.Methods:The data of ICC patients who underwent radical resection for the first time at Zhongshan Hospital, Fudan University from January 2014 to December 2017 were retrospectively analyzed. Of 167 patients who were enrolled, there were 104 males and 63 females, with the age of (60.3±10.9) years. Tumor tissues were collected for immunohistochemical staining and interpretation. Univariate Cox regression, LASSO regression and multivariate Cox regression were used to analyze influencing factors of postoperative long-term survival after ICC. R software was used to construct a nomogram in predicting ICC prognosis.Results:Cox regression analysis showed that TNM staging, poorly differentiated tumor, positive resection margin, positive mucin 5 expression and abnormal P53 expression to be independent risk factors associated with poor long-term survival after radical resection. The prognostic nomogram model of ICC was constructed based on these factors. The C-index was 0.821. The nomogram model consistency index had a high degree of prognostic differentiation. The 45° diagonal of the 3-year postoperative calibration curve which represented the actual survival fitted well with the segmented line which represented the predicted survival of the nomogram. The area under the receiver operating characteristic curve of the nomogram model was higher than that of AJCC TNM staging (0.894 vs. 0.803, z=4.10, P<0.001). The nomogram model was more effective in predicting postoperative survival of ICC patients than the TNM staging. Conclusion:TNM staging, poorly differentiated tumor, positive resection margin, positive mucin 5 expression and abnormal P53 expression were independent risk factors for postoperative survival of ICC. The nomogram model could better evaluate long-term prognosis of ICC patients after radical resection than the traditional TNM staging system.

ABSTRACT

Objective To explore the role of clinical pharmacists in rational drug use through the pharmacy care of an elderly pneumonia patient with Chlamydia psittaci infection and drug-induced liver injury. Methods The clinical pharmacists participated in the treatment of one patient with Chlamydia psittaci pneumonia and drug-induced liver injury. Based on the results of second-generation gene sequencing, the characteristics of the pathogen were learned by literature search. The clinical pharmacists monitored the patient’s liver and kidney function, provided a new medication treatment plan to Doctors, and performed patient education during the treatment. Results The initial empirical anti-infective treatment with teicoplanin and imipenem-cilastatin was not effective. After the diagnosis of Chlamydia psittaci and Candida albicans infection, the combination of doxycycline with azithromycin and fluconazole was administered. Drug-induced liver injury was found with this treatment. The clinical pharmacist proposed to switch to doxycycline and clarithromycin with co-administration of magnesium isoglycyrrhizinate and polyene phosphatidylcholine to protect the liver. With this new regime, patient's liver function was improved and the infection was under control. Conclusion Individualized pharmaceutical cares provided by clinical pharmacists helped the safe, rational and effective use of medications.

ABSTRACT

To conduct research and stipulate international standards of Chinese herbal medicine under the guildance of International Organization for Standardization (ISO) has become a new hot spot of internationalization and standardization of traditional Chinese medicines. International organization for standardization/technical committee of traditional Chinese medicine (ISO/TC249) provides a international platform to develop the standards of Chinese herbal medicine. Sinomenii Caulis, as a traditional Chinese medicine with obvious clinical effect which is used internationally, it’s necessary to establish a unified quality and safety control standards at international level. The current literature showed that there are many aliases of Sinomenii Caulis, and the problem of its variety confusion and adulteration is serious. Sinomenine-based alkaloids were the main pharmacological active components of Sinomenii Caulis. By analyzing the pharmacopoeias of China, Japan, South Korea and Europe, it was found that both Chinese and European Pharmacopoeias take sinomenine as the quality control indicator of Sinomenii Caulis. The Japanese and South Korean pharmacopoeias had similar quality control requirements of Sinomenii Caulis, and the South Korean pharmacopoeia pays more attention on safety requirements. Thus, it is suggested that setting ISO standards of Sinomenii Caulis requires the collection of global trade data and samples of Sinomenii Caulis for future quality and safety research.

ABSTRACT

OBJECTIVE@#To carry out single nucleotide polymorphism (SNP)-based chromosome microarray analysis (CMA) for a boy featuring global developmental delay.@*METHODS@#The SNP array was conducted for the child, and real-time PCR was used to validate its result and identify the origin of pathological copy number variants.@*RESULTS@#SNP array revealed that the patient has carried a de novo 2.5 Mb duplication at 2q22.3q23.3, which encompassed ACVR2A, KIF5C, MBD5, EPC2, LYPD6, LYPD6, MMADHC and ORC4 genes. Literature review suggested that the MBD5 gene from the duplicated region may have predisposed to the global developmental delay shown by the girl.@*CONCLUSION@#The patient's clinical phenotype was consistent to that of 2q23 duplication, for which the MBD5 gene may play a key role. CMA has provided an important tool for the diagnosis of patients with global developmental delay.

ABSTRACT

OBJECTIVE@#To carry out genome-wide copy number variations (CNVs) analysis for a boy with autism by using single nucleotide polymorphism array (SNP array).@*METHODS@#SNP array analysis was conducted for the boy and his parents, and the data was validated by real-time PCR. Correlation between the deleted genes and the phenotype was analyzed by reviewing the literature.@*RESULTS@#The patient was found to carry a terminal deletion of 18q22.3q23 (7.1 Mb), which involved FBXO15, ZNF407, ZADH2, TSHZ1, MBP and ADNP2 genes. No pathogenic CNVs were found in the parents. Comparison of the patient with cases reported in the literature suggested that the ZNF407 gene probably accounts for the autistic phenotype in these patients.@*CONCLUSION@#The autistic phenotype of the patient may be attributed to the 18q deletion, for which ZNF407 may be a critical candidate. SNP array has provided an useful tool for the study of molecular mechanism underlying autism.

ABSTRACT

Objective The effect of different doses of ethylnitrosourea(ENU)and cyclophosphamide(CP)on the loss rate of CD59 on peripheral blood erythrocytes was explored to optimize the detection method of Pig-a gene mutation. Methods According to the weight and loss rate of CD59 on peripheral blood erythrocytes,rats were divided into 4 groups:the control group,CP 40 mg/kg group,ENU 10 mg/kg group and ENU 40 mg/kg group(n=6). The control group was injected i.p. with PBS,other groups were injected i.p. with corresponding solutions. The body weight of rats on days 0,7,14,21, 28, 42 and 56 were recorded. At the same time, blood samples were collected and incubated with antibodies,and the loss rate of RBCCD59-was detected by flow cytometry. Results Compared with the control group, at different time points, the body weight and weight gain of ENU 10 mg/kg group and ENU 40 mg/kg group had no statistically significant difference(P > 0.05),while those in the CP 40 mg/kg group were significantly decreased(P <0.05). The loss rate of RBCCD59-was significantly increased in the CP 40 mg/kg group at 28,42 and 56 days, ENU 10 mg/kg group at 42 and 56 days,and ENU 40 mg/kg group at 7,14,21,28,42 and 56 days,(P < 0.05). The results showed a dose-response relationship. Conclusions Under the conditions of this Pig-a mutation detection method,ENU is superior to CP on raising loss rate of RBCCD59-,ENU 40 mg/kg is better than 10 mg/kg,and 28 days is suitable as the test period.

ABSTRACT

BACKGROUND:Numerous studies have shown that local lumbar stenosis can cause immunological abnormalities and local chronic inflammation, which is the main cause of pain. At present, studies on inflammatory factors and lumbar spinal stenosis mainly focused on intervertebral discs, facet joint and ligamenta flava. No reports addressed the relationship between inflammatory factor in vein of lumbar spinal canal and lumbar spinal stenosis. OBJECTIVE:To analyze the correlation of serum interleukin-1αand tumor necrosis factor-αlevels with lumbar spinal stenosis. METHODS:A total of 51 patients with lumbar spinal stenosis or lumbar vertebral burst fracture, who underwent posterior lumbar decompression in the Department of Spine Surgery, Shanghai East Hospital, Tongji University in China from September 2011 to December 2013, were enrol ed in this study. Visual analogue scale score of low back pain and Oswestry disability index were evaluated before treatment. Peripheral vein blood and venous blood in the vertebral canal were col ected from patients with lumbar spinal stenosis or lumbar vertebral burst fracture. The concentrations of serum interleukin-1αand tumor necrosis factor-αwere determined using enzyme-linked immunosorbent assay. RESULTS AND CONCLUSION:The concentration of interleukin-1αin degenerative lumbar stenosis group was significantly higher than that in the lumbar burst fracture group and peripheral veins (P<0.05). The more segments of lumbar spinal stenosis, the higher the venous serum interleukin-1αlevels were in the degenerative lumbar stenosis group, but the statistical difference was not significant. Linear correlation analysis results displayed that interleukin-1αlevels were positively associated with low back pain and disability scores in the degenerative lumbar stenosis group (r2=0.359 3, P<0.05;r2=0.526 4, P<0.05). These results indicated that the lumbar spinal venous inflammatory factors may be one of the reasons of low back pain and dysfunction in patients with degenerative lumbar spinal stenosis.

ABSTRACT

In conventional ear implantation surgery, clinical physicians usually make a surgery planning based on their observation on series of 2D X-ray images or CT images. Such a planning method requires the physicians to have a high level of clinical experience. Besides, the whole operation is unintuitive, and might have certain risk. Considering these facts, we have developed a computer-aided system for the surgery planning of the implantation of artificial ear based on CT imaging and 3D reconstruction techniques. The system effectively overcomes the main drawbacks in conventional surgery planning techniques, and it makes the surgery planning procedure more precise, safe, and intuitive.
