OBJECTIVETo explore the clinical efficacy and action mechanism of acupuncture for premature ovarian failure (POF).

METHODSAccording to prospective cohort study design, 30 cases were included. Based on theory of regulating Chong and Conception Vessels as well as soothing the liver and calming the nerves, acupuncture at Guanyuan (CV 4), Dahe (KI 12), Taixi (KI 3), Taichong (LR 3), Baihui (GV 20) was applied, three times per week and 3 months were considered as one session. Totally two sessions were performed. The menstruation condition, estradiol (E2), follicle-stimulating hormone (FSH) and scores of the clinical perimenopausal symptoms were taken as treatment outcomes.

RESULTSThe total effective rate was 86.7% (26/30) and the cured rate was 16.7% (5/30). The recovery rate of menstruation was 16.7% (5/30) and the regain rate of menstruation was 56.7% (17/30). After the treatment, the level of E2 was significantly increased from (45.41 +/- 18. 09) pmol/L to (59.07 +/- 24.21) pmol/L (P < 0.05), and the score of perimenopausal symptoms was obviously reduced from 14.28 +/- 8. 30 to 4.04 +/- 3.28 (P < 0.01). However, no statistical differences could be seen in FSH before and after treatment (P > 0.05).

CONCLUSIONAcupuncture has certain effect on improving menstruation and perimenopausal symptoms in POF patients, which is likely to he related with increasing the level of E2.

Objective To investigate the preventive effect of Indomethacin for post-ERCP pancreatitis and hyperamylasemia.Methods A total of 600 patients,who were undergoing ERCP,were randomly divided into 3 groups to receive anal Indomethacin (n=200),intravenous octreotide (n=200) or no special medication (n=200) before ERCP.The level of serum amylase before and 24h after ERCP were measured,and the rate of acute pancreatitis and hyperamylasemia after ERCP were assessed.Results Serum amylase levels before ERCP of all groups were normal.The mean serum amylase level of Indomethacin group (101.3±77.7 U/L) after ERCP was significantly lower than those of octreotide group ( 176.6±138.3 U/L,P =0.040 ]and control group (227.2±264.9 U/L,P=0.048),while there was no difference between octreotide group and control group ( P＞0.05 ).The incidence of post-ERCP pancreatitis in Indomethacin group (2.5％) was significantly lower than that of control group (9.5％,P=0.003),while there was no difference between octreotide group (4.5％) and control group ( P=0.05 ).The incidence of hyperamylasemia after ERCP in Indomethacin group (5.5％) was significantly lower than that of control group ( 13.5％,P=0.006 ),while there was no difference between octreotide group (10.0％) and control group ( P＞0.05 ).Conctusion Anal administration of Indomethacin before ERCP can effectively reduce the incidence of acute pancreatitis and hyperamylasemia after ERCP.

OBJECTIVETo evaluate the efficacy and safety of Chinese herbal medicine combined with systemic chemotherapy and/or regional arterial perfusion for pancreatic cancer with liver metastases (PCLM).

METHODSWe retrospectively selected 292 patients with PCLM who were treated by Chinese herbal medicine combined with systemic chemotherapy and/or regional arterial perfusion at Tianjin Medical University Cancer Hospital from January 2001 to December 2010. All patients were assigned to the Western medicine treatment group (157 cases) and the integrative medicine treatment group (135 cases). Patients in the Western medicine treatment group were treated with gemcitabine (GEM)-based chemotherapy, and partial of them received regional arterial perfusion. Those in the integrative medicine treatment group additionally took Chinese herbs of clearing heat and eliminating mass for at least 4 weeks. The median survival time (MST) , adverse reactions and the incidence of complications were observed.

RESULTSThere was no statistical significance in general data between the two groups (P > 0.05). There was statistical difference in MST between the two groups (4.8 months vs 5.5 months, P < 0.05). No death occurred during chemotherapy or regional arterial perfusion. All toxic or adverse reactions were tolerable.

CONCLUSIONChinese herbal medicine combined with systemic chemotherapy and/or regional arterial perfusion was effective and safe, and it could be optimally selected as palliative therapy for PCLM.

The primary object of this fundamental research was to survey the synergistic cardiovascular effects of iptakalim, a novel ATP-sensitive potassium channel (K(ATP)) opener, and clinical first-line antihypertensive drugs, such as calcium antagonists, thiazide diuretics and β receptor blockers by a 2 x 2 factorial-design experiment. It would provide a theoretical basis for the development of new combined antihypertensive therapy program after iptakalim is applied to the clinic. Amlodipine besylate, hydrochlorothiazide and propranolol were chosen as clinical first-line antihypertensive drugs. Blood pressure, heart rate (HR) and cardiac functions were observed in anesthetized normal rats by an eight-channel physiological recorder. The results showed that iptakalim monotherapy in a low dose could produce significant antihypertensive effect. There was no interaction between iptakalim and amlodipine on the maximal changes of systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial blood pressure (MABP), the left ventricular systolic pressure (LVSP), and the left ventricular end-diastolic pressure (LVEDP) (P > 0.05). However, the effects of combination iptakalim/amlodipine on the maximal changes of SBP, DBP, MABP, LVSP and LVEDP were more obvious than those of iptakalim or amlodipine monotherapy. And there was strong positive interaction between iptakalim and amlodipine on the maximal changes of HR (P>0.05). According to the maximal changes of DBP, MABP, LVSP and LVEDP (P < 0.05) of combination iptakalim with hydrochlorothiazide, there was strong positive interaction between them. But there was no interaction between iptakalim and hydrochlorothiazide on the maximal drop of SBP and HR (P > 0.05). According to the maximal drops of DBP, MABP of combination iptakalim with propranolol, there was strong positive interaction between them (P < 0.05). But there was no interaction between iptakalim and propranolol on the maximal changes of SBP, LVSP, LVEDP and HR (P > 0.05). In conclusion, it was the first time to study the effects of amlodipine, hydrochlorothiazide or propranolol, which had different mechanisms of action from iptakalim, on cardiovascular effects of iptakalim in anesthetized normal rats. This study proved that the combination of iptakalim with hydrochlorothiazide or propranolol respectively had significant synergism on lowering blood pressure, while the combination of iptakalim/amlodipine had additive action on lowering blood pressure. Meanwhile the antihypertensive effect was explicit, stable and long-lasting. Iptakalim thus appears suitable for the clinical treatment of hypertensive people who need two or more kinds of antihypertensive agents.

OBJECTIVETo construct plant expression pCAMBIA1301-PMI by substituting PMI for hygromycin resistance gene in pCAMBIA1301 and obtain transgenic Salvia miltiorrhiza f. alba using PMI-mannose selection system.

METHODThe 6-phosphomannose isomerase gene (PMI) of Escherichia coli was amplified by PCR. Sequence analysis showed that it shared 100% amino acids identities with the sequences of PMI genes isolates reported in the NCBI. Based on pCAMBIA1305, the plant expression pCAMBIA1305-PMI was constructed successfully by substituting PMI for hygromycin resistance gene in pCAMBIA1305. pCAMBIA1305-PMI was transformed into Agrobacterium tumefaciens LBA4404, and then the leaves of S. miltiorrhiza f. alba were inoculated in LBA4404 with pCAMBIA1305-PMI.

RESULTPlant expression pCAMBIA1301-PMI was successfully constructed and the leaves of S. miltiorrhiza f. alba inoculated in LBA4404 with pCAMBIA1305-PMI were selected on medium supplemented with a combination of 20 g x L(-1) mannose and 10 g x L(-1) sucrose as a carbon source. The transformation efficiency rate was 23.7%.

CONCLUSIONGenetic transformation was confirmed by PCR, indicating that a new method for obtaining transgenic S. miltiorrhiza f. alba plants was developed using PMI-mannose selection system.

Objective: To evaluate the accuracy of automated classification of ICD-O-3 morphology code from pathology reports by text-mining and support vector machine ( SVM ) , in order to provide basis for automated tumor coding in Chinese. Methods: The tumor report cards of Zhejiang residents from 2017 to 2019 were collected from Chronic Disease Surveillance Information Management System of Zhejiang Province. According to ICD-O-3, the keywords of the pathology reports were extracted, and SVM was used for automatic classification. The classification results were compared with those of 16 professionals with more than two years of experience in tumor coding, and the accuracy rate, recall rate and F-score were calculated for effect evaluation. Results: Totally 83 082 cases from 2017 to 2019 were included and were categorized into 17 morphological classifications, with 52 877 ( 63.65% ) cases of adenocarcinoma, squamous carcinoma and transitional cell carcinoma. A total of 1 090 keywords were enrolled into main corpus. The total F-score, accuracy rate and recall rate are 85.69, 77.20% and 96.27%, respectively. Conclusion Text-mining combined with SVM can improve the efficiency of ICD-O-3 morphology coding; however, the accuracy needs to be further improved.

ObjectiveTo explore the mechanism of extracorporeal shock wave (ESW) in treating osteogenic disorders and the ideal energy level. MethodsAfter success in marrow aspiration from patients' iliac crest, hMSCs were isolated by Percoll density gradient centrifugation and cultured in Dulbecco's modified Eagle's medium in a 5% CO2 and 37 ℃ incubator. Optimal ESW dose was determined by MTT of kinase-marked cytobiology. After hMSCs were exposed to ESW, their morphocytologic change, rate of adherence and doubling time were observed with IPCM. Enzyme cytochemistry reaction for the activity of alkaline phosphatase was also examined. ResultsESW of 5 kV and 100 times could increase cells' viability and proliferation (P<0.01), but higher than 7 kV would inhibit them. Rate of adherence of hMSCs in exposure group of passage 5 reached to 61.54%, which was significantly different from control group(P<0.05). Compared with control group, the MSCs' doubling time was short for 1.72 d (P<0.05). The curve of normal alkaline phosphatase activity of hMSCs was like type S, but ESW shortened its latent period, and promoted its peak time, which was significantly different from control group.ConclusionESW of 5 kV and 100 times can optimally promote the proliferation and activity of osteogen of hMSCs in vitro.

OBJECTIVETo investigate the effect of allergic rhinitis (AR) and its intervention on disease condition and medications in patients with juvenile-onset systemic lupus erythematosus (JSLE).

METHODSThe clinical data of 96 children diagnosed with JSLE were collected, and according to the presence or absence of AR or other allergic diseases, they were divided into AR group (n=44), non-AR group (n=20), and non-allergic group (n=32). The children in the AR group were randomly administered with or without intervention (n=22 each). All the children were given standard JSLE treatment. The systemic lupus erythematosus disease active index (SLEDAI) and application of hormones and immunosuppressants were compared between groups.

RESULTSThe AR and non-AR groups had significantly higher SLEDAI scores, daily cumulative doses of glucocorticoids, and number of types of immunosuppressants used than the non-allergic group before treatment (P<0.05), while there were no significant differences between the AR and non-AR groups (P>0.05). After one month of treatment, the AR group with intervention had significantly lower SLEDAI scores and daily cumulative doses of glucocorticoids than the AR group without intervention (P<0.05), while there was no significant difference in the application of immunosuppressants between these two groups (P>0.05). After 3 and 6 months of treatment, the AR group with intervention had significantly lower SLEDAI scores, daily cumulative doses of glucocorticoids, and number of types of immunosuppressants than the AR group without intervention (P<0.05).

CONCLUSIONSJSLE combined with allergic diseases such as AR has an adverse effect on disease condition and treatment, and the intervention for AR helps with the control of JSLE.

OBJECTIVETo investigate the role of fascin, an actin bundling protein, in the development and progression of human esophageal squamous cell carcinoma (ESCC), and explore its association with the clinicopathologic characteristics and 5-year survival of the patients.

METHODSUsing tissue array and immunohistochemistry, the expression of fascin was determined in 241 ESCC tissues and the corresponding normal esophageal mucosal tissues.

RESULTSESCC tissues showed a significantly higher overexpression rate of fascin than the corresponding normal esophageal mucosal tissues (68.9% vs 15.5%, P<0.05). The overexpression of fascin was correlated to lymph node metastasis and TMN stage, but not to the patients' age, gender, tumor differentiation and general classification. Survival analysis showed that abnormal expression of fascin was associated with the 5-year survival rate of patients with ESCC.

CONCLUSIONSThe abnormal expression of fascin may play an important role in the progression of ESCC, and detection of fascin expression may have important prognostic values.
