Kunming mice were infected by feeding 150?5 larvae of Trichinella spiralis,established was also a normal control group.Blood was collected from the ophthalmic venous plexus respectively on 7 d,21 d,35 d and 49 d after infection and IL-12 in the serum was detected by ELISA.The level of IL-12 in serum decreased in groups of 7 d,21 d,and 35 d,with a significant difference to the control(P0.05),suggesting that the serum IL-12 of the Trichinella spiralis-infected mice significantly decreased at the earlier stage but approached to normal at a later stage.

Objective:To investigate the prognostic factors and pathological characteristics of mixed subtype thyroid cancer (MSTC) .Methods:Data of 41 cases of MSTC, which were confirmed by postoperative pathology, among from 24, 912 cases of thyroid cancer admitted in Mar. 2005 to Aug. 2020 in the First Medical Center of Chinese People’s Liberation Army General Hospital, were retrospectively analyzed. 37 cases underwent surgical treatment, while 4 cases only underwent puncture to confirm the pathology due to physical conditions, and no surgical treatment was performed. The tumor size, number of lesions, capsule invasion, AJCC 8th TNM staging, surgical methods, radiotherapy and chemotherapy were collected. The MSTC patients in the group were followed up to obtain the postoperative situation. SPSS 25.0 and R studio statistical software was used for data processing, and Cox single factor and multivariate regression were used to analyze independent risk factors.Results:In the 41 cases, there were 9 cases of papillary carcinoma (PTC) mixed with follicular carcinoma (FTC) , and 8 cases of mixed medullary and follicular carcinoma (MMFTC) . There were 15 cases of poorly differentiated thyroid cancer (PDTC) , 4 cases of squamous cell carcinoma of thyroid (SCCT) , and 5 cases of undifferentiated thyroid carcinoma (ATC) . The median follow-up time was 18 months, and 11 patients died during the follow-up, with a mortality rate of 26.8%. Average onset age was (51.41+15.69) years. 4 cases had postoperative recurrence during the follow-up, including 2 cases of local recurrence, and 2 cases of distant metastasis. Single factor results showed that age, degree of tumor differentiation, surgical method, radiotherapy and chemotherapy were the risk factors affecting the prognosis of patients with MSTC ( P<0.05) . Multivariate analysis showed that age at diagnosis ( P=0.007) and surgical procedure ( P=0.017) were independent risk factors for prognosis in patients with MSTC. Conclusion:Middle-aged and elderly women are at high risk for MSTC, and the degree of tumor differentiation is proportional to survival. Due to the multi-type and pleomorphic pathological findings, a reasonable treatment plan has good effects on prognosis of MSTC.

Objective To evaluate the clinical effect of computed tomography?guided visceral nerve plexus ethanol neurolysis through post?curs of diaphragm approach in the treatment of patients with pancreatic cancer pain using,and study the safety and life quality improvement of patients . Methods A total of 58 patients suffered from pancreatic cancer pain,who were treated in the department of pain medicine of the First Hospital of China Medical University from October 2013 to December 2014,were recruited for the study. The patients were divided into two groups according to the willing of the patients and their families,group A(32 cases)was treated with Visceral Nerve Plexus ethanol Neurolysis,while group B(26 cas?es)was treated with oral opioid drugs. The analgesic effect,changes in the amount of opioid drugs,changes in the PSQI scores and the improvement of quality of life were evaluated before treatment and 1 day(T1),15 days(T15),30 days(T30),60 days(T60)after treatment. Record the adverse reactions in the course of treatment. Results All the patients of group A successfully received visceral nerve plexus ethanol neurolysis,the VAS scores,Karnofsky scores,and PSQI scores of all the observed time points(after the operation)were statistically different compared to those before treatment and group B. Statistically difference was also observed in quality of life between two groups(P<0.05). The amount of opioid drugs of group B was statistically increased than that of group A(P<0.01).The most common side effects in Group A were postural hypotension(6 cases),diar?rhea(2 cases),and intercostal neuralgia,while nausea(20 cases),constipation(11 cases)and dizziness(8 cases)were seen in the Group B. Con?clusion Visceral nerve plexus ethanol neurolysis through post?curs of diaphragm approach by the guide of CT is effective and safe for the patients with pancreatic cancer pain,and the complications were totally acceptable.

Aim Toinvestigatingtheinductionof CYPs in hepatocytes or HepG2 cells by triptolide(TP) andthepossiblemechanism.Methods AfterTPtreat-ment,the expression of CYPs in rat primary hepato-cytes or human HepG2 cells was detected by real-time PCR and Western blot assays.Specific inhibitors or gene knockdown method were employed to analyze the possiblemechanism.Results Theexpressionof CYP1A2,2C7,2C11,2C12,2D2,2E1 and 3A1 in rat primary hepatocytes was induced by TP.The fold was 19,2,31,3,21,88 and 34 at 50 nmol·L-1, respectively while at 100 nmol·L-1 it was 20,5,30,23,61,83 and 38,respectively.In HepG2 cells,the expression of human CYP1A1,2B6,2C9,2C19, 2D6,2E1 and 3A4 was also induced by TP.The ac-tivities of nuclear receptor PXR and CAR were inhibi-ted.TP upregulated p53 expression,and the induction of several CYPs caused by TP was blocked when p53 wasinhibited.Conclusions TPinducesCYPsexpres-sion in rat hepatocytes and HepG2 cells.Nuclear re-ceptors may not be involved in TP induced CYPs, while the mechanism may partly attribute to p53.

Objective To study the inhibition effects of antibacterial proteins from Musca domestica larvae on JEC and A375 tumour cells. Methods Antibacterial proteins with concentrations of 0.02%,0.1%,0.5%,2.5% and 12.5% were supplied in the culture of JEC and A375 tumour cells in vitro.The cell cycles and apoptosis of JEC and A375 tumour cells were detected by flow cytometry,and the apoptosis index(AI) was measured.The morphology of apoptotic cells was observed with HE stainings and AO staining.The culture without antibacterial proteins was served as control. ResultsThe ratio of apoptosis index/proliferation index(AI/PI) of JEC cells increased with the concentration of antibacterial proteins.The PI and apoptosis rate of 2.5% antibacterial proteins group and 12.5% antibacterial proteins group significantly increased,and G0/G1 significantly decreased.For A375 cells,there were significant differences in G2/M, S,G0/G1,G2/M,AI/PI and PI between 12.5% antibacterial proteins group and control group(P

Chemokines are small cytokines with chemotactic activity, they are involved in regulating immune responses and inflammatory responses. In the development of tumors, chemokines are multi-functional mediators that not only affect the infiltration of immune cells into the tumor, but also have an important impact on tumor growth, angiogenesis, invasion, and metastasis. Besides, they are important targets of tumor therapy. Here we review chemokines involved in the regulation of signaling pathways, analyze the mechanism of chemokines in the development of breast cancer, summarize the chemokines targeted drugs for breast cancer in recent years and make a prospect about the role of chemokines in anti-breast cancer therapy.

To analyze the characteristic of urinary protein spectrum in patients with stage III diabetic nephropathy (DN) and its compliance with traditional Chinese medicine (TCM)symptom, for the sake of providing a basis for clarifying the rules of TCM syndrome differentiation in DN. Adopting the traditional epidemiological retrospective method, thirty-eight TCM syndromes and urinary protein with medium or low molecular weight, as well as urinary enzyme, including 24 h urinary protein (Upro), urinary albumin( UAlb), urinary retinal binding protein( URBP), urinary cystatin C (UCysC), urinary N-acetyl-beta-D-glucosaminidase (UNAG), were collected from 108 patients with stage III DN, and a multiple factor regression analysis between them was conducted. As the results, the levels of Upro, UAlb, URBP, UCysC, and UNAG were increased in 108 patients with stage III DN. Qi-Yin deficiency type was the major type. The level of UAlb in patients with Qi-Yin deficiency type was significantly higher than those without Qi-Yin deficiency type (P < 0.05). The elevation of Upro with the factors as swift digestion with rapid hungering, lassitude and lack of strength, weakness of waist and knees was complied, the elevation of UA1b with the factors as dry mouth with desire to drink, the elevation of URBP with the factors as numbness of extremities, shortness of breath, the elevation of UCysC with the factors as clear urine in large amounts, and the elevation of UNAG with the factors as frequent micturition, were complied respectively. In conclusion, for 108 stage III DN patients. The increase in urinary protein spectrum including UAlb, URBP, UCysC, and UNAG is the major characteristic. Shen and Pi are the major organs related to the appearance of urinary protein; Pi-Shen deficiency is the basic pathogenesis. The level of UAlb is taken as one of the objective syndrome factors for Qi-Yin deficiency type. The levels of UNAG and UCysC are possibly the objective syndrome factors for Shen-Qi deficiency type.

OBJECTIVEAfter performed symptom-limited maximum cardiopulmonary exercise testing (CPET) before and after acute alkalized blood, we repeated CPET with pure oxygen.

METHODSFive volunteers, 3hr after alkalizing blood room air CPET, re-performed CPET inhaling from Douglas bag connected with pure oxygen tank. We compared with those of room air CPETs before and after alkalized blood.

RESULTSAfter alkalized blood oxygen CPET had a similar response pattern as those of CPETs before and after blood alkalization. During the CPET, all breath frequency, minute ventilation and tidal volume at each stage were similar to those of CPETs before and after alkalized blood (P > 0.05),except there was a lower peak tidal volume than those of both CPETs and a slightly higher resting minute ventilation only than CPET after alkalized blood (P > 0.05). After alkalized blood, oxygen CPET, all PaO2 and SaO2 and most Hb were lower than those of both CPETs (P < 0.05). The pHa and [HCO3-]a were higher than those of CPET before alkalized blood (P < 0.05); but were not CPET after alkalized blood (P > 0.05). PaCO2 was similar to that of CPET before alkalized blood (P > 0.05), but was lower than that of CPET after alkalized blood at resting and warm-up (P < 0.05); then was similar to both CPETs at anaerobic threshold (P > 0.05); but was higher at peak exercise higher than those of both CPETs (P < 0.01). Oxygen increased 2,3 volunteers' workload and time at AT and peak exercises.

CONCLUSIONRespiratory response pattern to oxygen CPET after alkalized blood is similar to those of both CPETs before and after alkalized blood. The CPET response is dominantly depended upon metabolic rate, but not levels of pHa, PaCO2 and PaO2.

In clinic, some urinary protein makers can dynamically and noninvasively reflect the degree of renal tubular injury in patients with diabetic nephropathy (DN). These urinary biomarkers of tubular damage are broadly divided into two categories. One is newfound, including kidney injury molecule-1 (Kim-1), neutrophil getatinase-associated lipocalin (NGAL), liver-type fatty acid-binding protein (L-FABP) and cystatin C (CysC); the other one is classical, including beta2 microglobulin (beta2-MG), retinal binding protein (RBP) and N-acetyl-beta-D-glucosaminidase (NAG). It is reported that, the increases in urinary protein markers are not only closely related to the damage of tubular epithelial cells in DN patients, but also can be ameliorated by the treatment with Chinese herbal compound preparations or Chinese herbal medicine. Recently, although urinary proteomics are used in the protein separation and identification, the traditional associated detection of urinary protein markers is more practical in clinic. At present, it is possible that the associated detection of urinary biomarkers of glomerular and tubular damages may be a feasible measure to reveal the clinical significance of urinary protein markers in DN patients and the interventional effects of Chinese herbal medicine.
