OBJECTIVETo investigate the expression of matrix metalloproteinase-2 (MMP-2) and insulin-like growth factor-1 (IGF-1) in gastric carcinoma and their clinicopathological significance.

METHODSExpressions of MMP-2 and IGF-1 were examined by using immunohistochemical SP staining and cross-compared with clinicopathological features of gastric carcinoma.

RESULTSHigh expression of MMP-2 and IGF-1 were observed in 70.4% (307/436) and 49.5% (216/436) of gastric carcinoma tissues respectively, significantly higher than those in non-tumor gastric mucosa (3.3% and 5.4%, respectively; all P < 0.05). The high expression rate of MMP-2 and IGF-1 were significantly associated with the patient age, tumor size, tumor location, Lauren classification, TNM staging, depth of tumor infiltration, presence of vessel invasion, lymph node and distant metastasis (all P < 0.05). In addition, the expression of MMP-2 was positively linked with the expression level of IGF-1 (P < 0.05). Univariate analysis showed that high expression of MMP-2, was significantly associated with poor prognosis of tumor of TNM stage I and II (all P < 0.05), high expression of IGF-1 was significantly correlated with poor prognosis of patients with TNM stage I, II and III tumor (all P < 0.05). Cox multivariate analysis indicated that the high expressions of MMP-2 and IGF-1 could be independent prognostic indices for gastric carcinoma.

CONCLUSIONSHigh expression of MMP-2 and IGF-1 proteins are significantly correlated with the invasion and metastasis of gastric carcinoma, it is helpful to simultaneously detect the expressions of MMP-2 and IGF-1 proteins in predicting prognosis of patients with gastric carcinoma.

OBJECTIVETo define the anatomical approach, anatomical planes and related vessels and nerves to create a safe and reproducible combined sublingual and bi-vestibular access for trans-oral video-assisted thyroidectomy.

METHODSFrom November 2009 to May 2011, twenty-five embalmed human specimens were dissected for anatomical information of the cervical region, the mandible region and the supra-hyoid muscles. On twenty fresh frozen human specimens after an experimental trans-oral endoscopic thyroidectomy, the related vascular, neural structures and muscles were evaluated.

RESULTSThe optical access port was placed in the midline sublingual. The geniohyoid muscle, mylohyoid muscle and the anterior belly of the digastric muscle were divided in the midline in order to reach the plane under the platysma muscle. The mucosa was sagittal incised bilaterally in the vestibular of oral cavity for working trocar, at the level of the first molar of the mandible. The working trocar reached directly the periosteum of the mandible, under the facial vessel and the marginal branch of facial nerve, and then passed below the platysma muscle into the infra-laryngeal working area. The distance from mental nerve to mandibular midline and between mental nerve and facial artery were (25.8 ± 0.9) mm and (29.4 ± 0.9) mm respectively. Anatomical dissections showed that after an experimental trans-oral combined sublingual and bi-vestibular access, all muscles of the floor of the oral cavity as well as the related vascular and neural structures are intact. The maximum nodule size of the resected specimens in the totally trans-oral approach was up to 50 mm.

CONCLUSIONThe combined sublingual and bi-vestibular access of trans-oral video-assisted thyroidectomy is safe and reproducible.

Objective To analyze the results of application on China Infectious Diseases Automated-alert and Response System(CIDARS)and for further improving the system. Methods Amount of signal, proportion of signal responded, time to signal response, manner of signal verification and the outcome of each signal in CIDARS were descriptively analyzed from July 1,2008to June 30, 2010. Results A total of 533 829 signals were generated nationwide on 28 kinds of infectious diseases in the system. 97.13% of the signals had been responded and the median time to response was 1.1 hours. Among them, 2472 signals were generated by the fixed-value detection method which involved 9 kinds of diseases after the preliminary verification, field investigation and laboratory tests. 2202 signals were excluded, and finally 246 cholera cases, 15 plague cases and 9H5N1 cases as well as 39 outbreaks of cholera were confirmed. 531 357 signals were generated by the other method - the 'moving percentile method' which involved 19 kinds of diseases. The average amount of signal per county per week was 1.65, with 6603 signals(1.24%)preliminarily verified as suspected outbreaks and 1594 outbreaks were finally confirmed by further field investigation. For diseases in CIDARS, the proportion of signals related to suspected outbreaks to all triggered signals showed a positive correlation with the proportion of cases related to outbreaks of all the reported cases (r=0.963, P＜0.01). Conclusion The signals of CIDARS were responded timely, and the signal could act as a clue for potential outbreaks, which helped enhancing the ability on outbreaks detection for local public health departments.

OBJECTIVETo study the anti-inflammatory and analgesic actions of Aike Mixture (AKM).

METHODSA total of 100 male mice were randomly assigned into 5 groups: a normal control group, a drug control group (a hydrocortisone subgroup and an atropine subgroup), a high-dose AKM group, a mid-dose AKM group and a low-dose AKM group. Xylene was spread on the left ear of the experimental mice to induce inflammation, and 1% acetic acid solution injected into the abdominal cavity to produce pain so as to cause the body bend. Different doses of AKM were given and their actions observed.

RESULTSAKM had obvious anti-inflammatory effect on the xylene-induced ear tumefaction and inhibited the pain-caused body bend in the AKM groups, with significant difference from the normal control (P < 0.01).

CONCLUSIONAKM has good anti-inflammatory and analgesic effects, which is of clinical significance in the treatment of chronic prostatitis.

Aging is the most basic life feature of organisms. It is a phenomenon of dysfunction of cells,tissues and organs under the influence of external environment and internal factors during the growth of organisms. During the process,many cellular signaling pathways and biologically active substances,such as insulin/insulin-like growth factor( IGF)-1 signaling( IIS) pathway,apoptotic signaling pathway,mTOR signaling pathway,AMPK pathway,sirtuin pathway,deacetylases have been found to be closely related to the molecular mechanism of aging. Modern studies have indicated that anti-aging natural compounds can cause great side effects,while delaying aging and even inducing another disease,which is against with the purpose of delaying aging and achieving healthy aging. Therefore,the researches of anti-aging traditional Chinese medicines with fewer side effects are extremely important. Based on the different mechanisms and theories of aging,many traditional Chinese medicines have been discovered to be related to anti-aging. As one of the most important model organisms,Drosophila melanogaster has been widely used in studies of aging process in recent years. In this paper,we reviewed three important signaling pathways related to aging,such as insulin/insulin-like growth factor( IGF)-1 signaling( IIS) pathway,m TOR pathway,AMPK pathway,and screened out anti-aging traditional Chinese medicines based on D. melanogaster in recent years.

OBJECTIVE: To explore the therapeutic effect and the mechanism of the adjuvant treatment with moxibustion on coronavirus disease 2019 (COVID-19). METHODS: A total of 95 patients with COVID-19 were randomly divided into a moxibustion group (45 cases) and a basic treatment group (50 cases). The routine treatment of western medicine was applied in the patients of both groups. In the moxibustion group, on the base of the treatment of western medicine, moxibustion was applied to Dazhui (GV 14), Feishu (BL 13), Qihai (CV 6) and Zusanli (ST 36), once daily and consecutively for 14 days. At the end of treatment courses, clinical symptom scores for cough, asthmatic breathing, chest oppression and short breath, as well as their remission rates were compared between the two groups before and after treatment. Before and after treatment, the white blood cell (WBC) count, the levels of c-reactive protein (CRP) and interleukin-6 (IL-6) and the absolute number of T lymphocyte subsets, i.e. , and of the peripheral blood were compared in the patients between the two groups. The principal component analysis was adopted to analyze the common data extracted from the above 10 clinical indexes variables and comprehensively evaluate the differences in the therapeutic effect of two regimens. RESULTS: The clinical symptom scores were all decreased after treatment in both of the moxibustion group and the basic treatment group as compared with those before treatment ( CONCLUSION On the base of the routine treatment with western medicine, moxibustion therapy supplemented relieves the clinical symptoms, reduces the levels of inflammatory indexes, i.e. IL-6 and CRP as well as improves the absolute number of peripheral T lymphocyte subsets. The clinical therapeutic effect of such regimen with moxibustion supplemented is significantly better than the simple routine treatment of western medicine.

Objective: To investigate the prognostic value of clonal gene mutations detected by second-generation sequencing in patients with positive RUNX1-RUNX1T1 acute myeloid leukemia (AML) who received high-dose chemotherapy or autologous transplantation (intensive consolidation therapy) in the first complete remission (CR(1)) state. Methods: 79 AML patients with positive RUNX1-RUNX1T1 who received intensive consolidation therapy in CR(1) state from July 2011 to August 2017 were analyzed retrospectively. Kaplan-Meier curve and Cox regression model were used to figure out the effect of leukocyte counts at onset and gene mutations for prognosis. Results: C-KIT, FLT3, CEBPA and DNMT3A gene mutations were found in 25 (31.6%) , 6 (7.6%) , 7 (8.9%) and 1 (1.3%) patient among the population. Mutations in C-KIT exon17 and C-KIT exon8 were detected in 19 (24.1%) and 5 (6.3%) cases, respectively, and mutations of FLT3-ITD were confirmed in 5 (6.3%) cases. The higher leukocyte counts presented at onset of leukemia, the shorter overall survival (OS) was seen in these patients (P=0.03) . Patients with C-KIT exon17 mutation had significantly shorter OS (P=0.01) and disease free survival (DFS) (P=0.006) compared with those without gene mutations, and patients with FLT3-ITD gene mutation got the inferior OS (P=0.048) and DFS (P=0.071) . Conclusion: In AML patients with positive RUNX1-RUNX1T1 receiving intensive consolidation therapy, the white blood cell counts at onset of leukemia, C-KIT mutations in exon 17, and FLT3-ITD gene mutations suggest poor prognosis, which would contribute to elaborate risk stratification, personalized treatment and predict prognosis for these patients.
