ABSTRACT
Objective:To study the mechanism of Yangyin Yiqi mixture on the clinical symptoms in convalescent period of different types of pneumonia based on network pharmacology, so as to provide more options for the prevention and treatment of pneumonia with Traditional Chinese Medicine (TCM).Methods:Based on the TCM theory of "treating different diseases with the same method", the Integrative Pharmacology-Based Research Platform of Traditional Chinese Medicine (TCMIP) V 2.0 was used to screen the active components, action targets and disease targets of the herbs in Yangyin Yiqi mixture. The disease-target-medicine network map was constructed by Cytoscape software and the Reactome enrichment analysis of key targets were carried out.Results:Seven different types of clinical sympotms of pneumonia in convalescent period were established, including fatigue, tachypnea, thirst, palpitations, hyperhidrosis, poor appetite and cough. After the screening, a total of 276 active components and 177 key targets were obtained, 37 common targets of this herb and pneumonia were obtained. The key targets were associated with cell metabolism, apoptosis, inflammatory response, immune response, and stress response, etc. There are 17 common targets between Polygonatum and 7 clinical symptoms in the recovery period of different types of pneumonia. Reactome enrichment analysis showed that the pathways involved in the core genes of Yangyin Yiqi mixture in the treatment of the main symptoms of different types of pneumonia in the recovery period were mainly enriched in: by regulating genes and protein translation to affect the virus or cell function, immune regulation and inflammatory response and regulate the function of nervous system, and prevent viral canceration.Conclusions:The effective components in Yangyin Yiqi mixture may regulate phosphatidylinositol 3-kinase (PI3K), interleukin-4, interleukin-13 (IL-4, IL-13) and inhibitory kappa protein (IκBα) by intervention of PIK3CA, MAPK3, BCL2 and NF-κB2 and other targets to promote the recovery of pneumonia. This study could provide a theoretical basis for the prevention and treatment of pneumonia in the recovery period.
ABSTRACT
Osteoporosis results in decreased bone mass, impaired bone strength and bone microstructure, and thus can easily cause bone fracture. Osteoporosis is one of the common diseases troubling the aging people. Due to the decreased activity of osteoblasts as well as impaired osteogenic differentiation of mesenchymal stem cells, the repair of bone defects accompanied with osteoporosis is very limited. It is a promising way to enhance the healing effect of such bone defect through implanting biomaterials with improved physical and chemical properties as well as elevated bioactivities, since it can mediate the activities of osteogenesis related cells in situ. The author summarizes the popular methods for the modification of biomaterials used for repairing bone defect caused by osteoporotic fractures and provides a prospect in this field, with the aim to provide a reference for the treatment of osteoporotic fractures.

ABSTRACT
Objective:To explore the predictive value of serum thyroglobulin autoantibody (TgAb) for recurrence / metastasisin of thyroglobulin (TG)-negative and TgAb-positive patients with differentiated thyroid carcinoma(DTC) after thyroid ablation.Methods:The clinical data of 57 patients with DTC,undergoing complete resection of thyroid tissue,TG negative and TgAb positive,who were reviewed in Liaocheng People's Hospital during April 2013 to April 2015,were selected and divided into recurrence/metastasis group (n=20) and no recurrence/metastasis group (n=37).The TG and TgAb levels in the two groups were detected and compared by the electrochemical luminescence method,the sensitivity,specificity,positive predictive value and negative predictive value of TgAb in the diagnosis of DTC recurrence / metastasis were analyzed;the independent risk factors of DTC recurrence / metastasis were analyzed by Logistic regression.Results:The TgAb levels(72～3850 IU/mL) in the recurrence/metastasis group was higher than that(18～3638 IU/mL) in the no recurrence/metastasis group,the difference was statistically significant (P＜0.05).The sensitivity,specificity,positive predictive value,negative preictive value of TgAb in the diagnosis of recurrence/metastasis of DTC were 85.71％,83.33％,75.00％,90.91％,respectively.Logistic Regression analysis showed that the 100≤ TgAb ＜204 IU/mL,204≤ TgAb≤ 1000IU/mL,and ＞ 1000IU/rnL levels of TgAb were the independent risk factors of rucurrence/metastasis ofDTC (OR=1.267,2.853,6.791,P＜0.05).Conclusion:TgAb can be used as evaluation of an important index of the recurrence/metastasis of patients with DTC when serum thyroglobulin (TG) was negative and TgAb was positive after thyroid ablation.The higher the TgAb levels,the more probability of the recurrence/metastasis.
ABSTRACT
Objective To investigate the feasibility of laparoscopic endoscopic cooperative dissection without mucosa injury for patients with small gastric stromal tumor. Methods Fifteen patients with small gastric stromal tumor underwent laparoscopy and endoscopy combination therapy from January 2015 to October 2016. The gastric serous layer was cut open after submucosal injection, and then tumor was removed without mucosa injury under laparoscope. The clinical data were retrospectively analyzed. Results All of the 15 patients successfully completed the operation,and no one conversed to open surgery because of intraoperative complications. The operation time was 53.4±15.8 min, and the intraoperative blood loss was 15.2±3.5 mL. The gastric tube was pulled out on the day of operation.The mean time of recovering liquid diet after operation was 1.6±0.5 days, and the length of postoperative hospital stay was 3.3 ± 0.6 days. All the specimen had complete pseudocapsule,and their pathology results were all gastric stromal tumors,including 12 cases of very low risk degree, 2 low risk degree, and 1 middle risk degree. Conclusion Laparoscopic endoscopic cooperative dissection for small gastric stromal tumor has satisfactory short-term outcomes and shows a quick postoperative recovery,which meets the idea of minimally invasive surgery and rapid recovery. It is a new choice of treatment for patients with small gastric stromal tumor.
ABSTRACT
Background and purpose:Multiple microRNAs (miRNAs) are abnormally expressed in breast cancer and play an important role in the regulation of breast cancer. miRNAs may be a new target for the treatment of breast cancer. This study aimed to investigate the expression of miR-199a-3p in breast cancer and the effect of miR-199a-3p on proliferation and apoptosis of breast cancer.Methods:Real-time PCR was used to test the expression of miR-199a-3p in breast cancer tissues, normal breast tissues, breast cancer cells and normal breast cells. Overexpression (or silencing the expression) of miR-199a-3p was conducted by transfecting MDA-MB-231 with miR-199a-3p mimics (or inhibitors). The proliferation of MDA-MB-231 was detected by MTT method. The apoptosis of MDA-MB-231 was investigated by Hoechst staining and caspase-3 activity assay kit.Results:Compared to corresponding non-tumor breast tissues (or normal breast cell HBL-100), lower levels of miR-199a-3p were expressed in breast cancer tissues or breast cancer cells. Overexpression of miR-199a-3p induced by miR-199a-3p mimic inhibited the proliferation and promoted the apoptosis of MDA-MB-231, while silencing the expression of miR-199a-3p induced by miR-199a-3p in-hibitor increased the proliferation and suppressed the apoptosis of MDA-MB-231.Conclusion:The expression of miR-199a-3p is lower in breast cancer, which shows its tumor suppression effect by regulating the proliferation and apoptosis of breast cancer cells.

And there was no significant difference in the incidence of hypoglycemia [OR=0.97,95%CI(0.91,1.03),P=0.25];the degree of body mass gain ininsulin detemir was significantly lower than insulin glargine group [MD=-0.95,95%CI(-1.06,-0.85),P=0.003],but the in-cidence of injection site reactions was significantly higher than insulin glargine group [OR=2.28,95%CI(1.16,4.50),P=0.02],the differences were statistically significant. CONCLUSIONS:The insulin glargine has better efficacy,than insulin detemir with lower incidence of injection site reactions but higher degree of body mass gain than insulin detemir in the treatment of type 2 diabetes.
ABSTRACT
Objective:Colorectal cancer screening was performed on a general population with age ranging between 40 and 74 years old to evaluate the screening effects of questionnaire survey, fecal occult blood (FOB) test, and colonoscopy, as well as to provide some implications of colorectal cancer screening strategies. Methods: Two-step screening model of questionnaire survey combined with FOB test was applied for the screening. Colonoscopy was conducted in a high-risk population identified through preliminary screening as final diagnosis. Results:Based on the 2,117,304 cases screened, the screening compliance was 39.72%, and 126,118 cases (5.96%) were identified as high risk. Colonoscopies were performed on 25,837 cases, of which 8,095, 1,236, 134, 112, and 336 were identified as adenoma, advanced adenoma, severe dysplasia lesions, early cancer, and advanced cancer, respectively. The early stage di-agnostic rate was 81.52%. Conclusion:The colorectal cancer screening method performed in Tianjin can significantly concentrate on the high-risk population with colorectal cancer, increase the positivity rate of total colonoscopy, and economize medical resources.
ABSTRACT
Objective: To evaluate the post-operative mortality of left ventricular end-diastolic pressure (LVEDP) during primary percutaneous coronary intervention (PCI) in patients with acute ST-segment elevation myocardial infarction (STEMI). Methods: We retrospectively analyzed 255 patients with new onset of STEMI who received primary PCI in our hospital and all patients received LVEDP measurement before coronary artery opening. According to LVEDP value, the patients were divided into 2 groups: LVEDP≤14 mmHg group,n=155 and LVEDP>14 mmHg group,n=100. The post-operative mortality up to 6 months was observed, and the effect of LVEDP on death rate was studied by Cox regression analysis. Results: Compared with LVEDP≤14 mmHg group, the patients in LVEDP>14 mmHg group had the 6 months mortality at HR=4.26, 95% CI (1.13-16.08),P=0.03. Relevant study presented that LVEDP was slightly related to LVEF (r=-0.267, P=0.001) and BNP (r=-0.154,P=0.041). Multi-regression analysis indicated that with adjusted LVEF and BNP, LVEDP was the independent predictor for post-operative mortality up to 6 months in acute STEMI patients after PCI. Conclusion: The LVEDP value measured during PCI procedure is the independent predictor for mortality after PCI in patients with new onset of STEMI.
ABSTRACT
Objective To identify the role of microRNA-17(miR-17)in human glioma U87 cells invasion which may regulate expression of matriv metalloproteinase(MMP)-2.Methods U87 cells were cultured in vitro,while changes in cellular morphology were observed by phase contrast microscope.The miR-17 which might regulate the expression of MMP-2 was predicted by bioinformatics and identified using dual luciferase report system.Expressions of miR-17 and MMP-2 were determined using real-time PCR and Western blot after transfection of miR-17 mimics.The invasion of U87 cells was detected in vitro by Transwell chamber.Results Expression of MMP-2 was positive by immunofluorescence cytochemistry. Using dual luciferase reporter system,miR-17 could inhibit the expression of MMP-2 by binding to its mRNA 3′UTR. Results of real-time PCR and Western blot showed that over-expression of miR-17 down-regulated expression of MMP-2. The invasion of U87 cells was suppressed by over-expression of miR-17.Conclusion MiR-17 may negatively regulate expression of MMP-2 in human glioma U87 cells and inhibit cell invasion.

ABSTRACT
<p><b>OBJECTIVE</b>To detect memory B lymphocyte (Bm) in peripheral blood (PB) of immune-related pancytopenia (IRP).</p><p><b>METHODS</b>86 patients with IRP and 11 health volunteers were enrolled in this study. Bm (CD5⁺ CD19⁺ CD27⁺) and bone marrow mononucleated cell antibodies (BMMNC-Ab) were determined via fluorescence-activated cell sorting, and clinical outcomes of these patients were analyzed.</p><p><b>RESULTS</b>(1)43 initial patients achieved obvious remission in all 52 initial cases after conventional immunosuppression therapy. 16 relapsed patients with IRP received Rituximab (RTX) and 14 cases achieved obvious remission, among which 7 cases were refractory to conventional immunosuppression therapy, 5 cases exhibited obvious remission, and 2 cases did not respond. Other 18 relapsed cases received conventional immunosuppression therapy and 13 cases achieved obvious remission. (1)The level of Bm in PB in 52 initial patients with IRP was(1.81 ± 0.97)%, and no significant difference was observed between the initial patients and health volunteers (1.75 ± 0.55)% (P>0.05). The level of Bm in PB in 34 relapsed patients with IRP was obviously higher than that in the initial IRP patients and health volunteers (P<0.05). Significant difference was observed in the level of Bm in PB in 16 relapsed IRP patients between pre-therapy and post-therapy with RTX (P<0.05). No statistical difference was found between the remission and no-response groups in relapsed patients treated with RTX. RTX regimen produced more effective outcome than conventional immunosuppression therapy, which better eliminated Bm than the latter (P<0.05). Initial patients with IRP who relapsed within a two-year follow-up period had a lower level of Bm in PB compared with un-relapsed patients (P<0.05). Majority of BMMNC- Ab antibodies in relapsed patients were IgG (82.4%) and IgM (69.2%) autoantibodies in patients with initial IRP.</p><p><b>CONCLUSION</b>The level of Bm in PB was associated with relapsed patients with IRP. Bm did not respond to conventional immunosuppression therapy,but responded to RTX.</p>

The stump of an occluded middle cerebral artery [MCA] is a rare but important aneurysm mimic. A 57-year-old male was admitted due to recurrent onset of transient ischemic attack. Computed tomography angiography [CTA] and digital subtraction angiography [DSA] showed a total obstruction in the right MCA with moyamoya phenomenon at distal trunks and a protruding lesion in the left MCA bifurcation. The patient was diagnosed with left MCA bifurcation aneurysm. Intraoperatively, the lesion was found to be an occluded right MCA stump. Encephalomyoarteriosynangiosis was performed, and the patient remained symptom-free at the 6-month follow-up. The possibility of a vascular stump should be considered when an aneurismal lesion is present at the MCA bifurcation with moyamoya phenomenon at distal trunks

ABSTRACT
ObjectiveTo evaluate the feasibility and outcome of overnight laparoscopie cholecystectomy (OLC).MethodsThe clinical data of 149 patients with cholecystolithiasis or gallbladder polyps who were admitted to the Tianjin People's Hospital from October 2008 to December 2010 were retrospectively analyzed.All the patients underwent LC in the morning and were discharged 24 hours later.Modified Aldrete scoring was done 4-6hours after LC.Patients were contacted by telephone 3 days after LC and reexamined in the out-patient department 7 days after LC.The hospital cost of patients who underwent OLC or LC was compared using the t test.Results OLC was successfully performed on 149 patients,and the modified Aldrete scores of 130 patients were above 9.The visual analogue scale (VAS) of 118 patients were under 4,and the VAS of 31 patients were above 4.The condition of the 31 patients were closely monitered,and were administered morphine.Of the 149 patieuts,144were discharged 24 hours after operation,and the remaining 5 patients were admitted to general ward because of fever,peritoneal effusion or abdominal pain.The incidence of postoperative complication was 2.0％ (3/149) and the mortality was 0.All the patients were followed up,and none of the patients had an emergency readmission.The duration of incapacity was 5.2 days (range,2-7 days).The mean hospital cost of patients who received OLC was ( 7888 ± 396 ) yuan,which was significantly lower than ( 12121 ± 960) yuan of patients who received LC ( t =38.97,P ＜ 0.05 ).ConclusionOLC is effective and safe,and meets the requirement of health insurance policy.
ABSTRACT
ObjectiveTo investigate the imaging characteristics of solitary fibrous tumor(SFT).MethodsThis study included 11 cases with SFT proved by pathological results.The imaging manifestations were retrospectively reviewed and analyzed in comparison with surgical and pathological results. Among them,8 patients underwent CT plain scan (1/8) or enhanced scan (7/8),4 patients underwent MR plain scan (2/4) or enhanced scan (2/4),and only 1 patient underwent both CT and MR scan.Results( 1 )SFT were located in the thoracic cavity(2/11 ),abdominal and pelvis(5/11 ),and somatic soft tissues (4/11 ).The average tumor size was 11.8 cm ( 2.5 to 23.0 cm).Among them,4 tumors were round or ellipse,and 7 tumors were irregular.Eight tumors had well-defined contours,and the others showed illdefined contours.(2)On CT scan,all SFTs showed inhomogeneous density with low density areas.Calcification was seen in I case,and hemorrhagic foci were detected in 2 cases.(3)On MR scan,all SFTs showed intermediate signal intensity on T1 WI.Three tumors were slightly hyperintense and the other was hypointense on T2WI.All of them were rich of vascular signal voids.Three tumors,including 2 tumors with scattered long T1 and T2 signal and 1 tumor in the liver with hyperintense haemorrhage,displayed inhomogeneous mixed signal.One tumor in the orbit showed homogeneous signal.(4)On enhanced scan,9 tumors showed irregular enhancement with multiple circuitous vessels in the arterial phase,and continuous or progressive enhancement with patch non-enhanced areas in the venous phase.( 5 ) Histologically,SFTs were composed of juxtaposed hyper- and hypo-cellular spindle cells,dense collagenous stromas and numerous thin-walled blood vessels with a staghorn configuration.Conclusion The possibility of SFT should be considered when a single soft tissue mass with sharp border,inhomogeneous density is detected,especially with inhomogeneous enhancement maintaining in the venous phase.
