Objective To explore the role of COX-2 and VEGF in oncongensis and development of gestation-al trophoblastic disease,and evaluate prognosis of gestational trophoblastic tumor. Methods The expression of COX-2 and VEGF in normal chorion of early gestation and in gestational trophoblastic disease were detected by immunohis-tochemistry. Results In gestational trophoblastic tumor group,the positive rate of COX-2 and VEGF were significantly highter than that of normal chorion of early gestation group and the hydatidiform mole group respectively ( P < 0.01). There were positive correlation between COX-2 and VEGF in gestational trophoblastic tumor ( r = 0.795, P < 0.01). Conclusion The collaborative and over expression of COX-2 and VEGF were probably associated with the malignant change of trophoblastic cell,which suggest the worse prognosis of the gestational trophoblastic disease.

OBJECTIVE:To optimize the extraction process for the preparation of Paeonia lactiflora formula granules and establish an HPLC method for the determination of Paeoniflorin in the samples.METHODS:The optimum water extraction process was selected by the L9(34)orthogonal design and the content of Paeoniflorin in formula granules was analyzed by HPLC.The HPLC assay was performed on a crosmosil C18-MS-II(250mm? 4.6mm,5? m)column.The mobile phase was employed by using acetonitrile-0.1% phosphoric acid(14∶ 86).The detection wavelength was set at 230 nm and the system was operated at 25℃.RESULTS:The optimum extraction conditions were to reflux for 3 times with 12 fold water and each time for one hour.The extraction rate of Paeoniflorin was 85.7% and the dried extraction yield was 34.4%.The peak area had a good linearity with the concentration of Paeoniflorin and the linear range was 0.128～ 0.640? g(r=0.999 8).The average recovery was 100.76% and RSD was 1.26%.CONCLUSION:The preparation process of Paeonia lactiflora formula granules was stable and feasible.The HPLC method for quality control was accurate and suitable.

Objective To explore the effects of different dose rates of X-ray under the same dose on cell clonogenic formation in non-small-cell lung cancer cell line A549 in order to provide experimental basis for clinical radiotherapy plan. Methods The A549 cells were cultured at low density and irradiated with X-rays at dose of 4 Gy and selected dose rates of 1, 2, 4 and 6 Gy/min, respectively, from a linear accelerator. The 8th day after irradiation, the cells were fixed and stained with Giemsa solution, and colonies containing at least 50 cells were counted. The plating efficiency and surviving fraction were calculated. Results The clonogenic number in non-irradiated cells was 88.6±4.6. The numbers were significantly reduced in irradiated cells at dose rate 1, 2, 4 and 6 Gy/min (12.3±3.4, 9.0±0.8, 5.6±1.0, 11.5±1.7, respectively) than that in non-irradiated control cells (F=678.799, P<0.05). The plating efficiencies were decreased in irradiated cells, especially in 4 Gy/min irradiated cells, which was lower than that in any of the other three dose rate groups (P< 0.05). Conclusions Though at same radiation dose, cancer cells have different clonogenic formation efficiency when irradiation with X-ray at different dose rates. Thus, treatment with optimal dose rate may improve the radiotherapy efficacy.

Objective To observe the effects of different iodine intake on the thyroid tumor growth and thyroid function in the orthotopic nude mice model of human papillary thyroid carcinoma (PTC) cell line TPC-1.Methods Human PTC cell line TPC-1 (2 × 105) was injected into the left thyroid gland of nude mice.After the operation,the nude mice were randomly divided into three groups:low iodine group (LI),normal iodine group (NI),and high iodine group(HI,50 folds of normal iodine) based on the iodine levels contained in their diet.4 and 12 weeks later,the nude mice were executed,then their thyroid tumors were removed and weighted.The levels of urinary iodine were measured with As3+-Ce4+ catalytic spectrophotometry using ammonium persulfate digestion method.The thyroid hormone level was detected using chemiluminescent immunoassay.The morphology and structure of thyroid tumor tissue was observed by microscope.Results The iodine intervention feeding was successful according to urinary iodine level of LI,NI,and HI groups,paralleled to their iodine intakes.However,the difference of the weight of thyroid tumor in three groups had no statistical significance(P＞0.05).At 4 weeks,compared with control group,the levels of thyroid hormones were normal in NI group,while lower T4 and normal T3 were found in LI group.However,T4 was higher and T3 was lower in HI group (P＜0.05).At 12 weeks,the levels of thyroid hormones all were decreased due to the enlargement of thyroid gland tumor in NI,LI and HI groups.T4 and T3 in LI group were the lowest among three groups,even T4 was below detection limit.T4 was normal and T3 was lower in HI group as compared to control group.Conclusion Iodine intake may not significantly affect tumor growth in the orthotopic nude mice model of human PTC cell line TPC-1,but it has a significant effect on the synthesis of thyroid hormones.

Objective To observe and compare the different orthotopic models of papillary thyroid cancer ( PTC) cell lines of RET/PTC1 rearrangement and BRAFV600E mutation in nude mice. Methods Human PTC cell lines TPC-1, BHP5-16 and BHP2-7 were used. The genotypes of RET/PTC1 rearrangement and BRAFV600E mutation were determined by realtime-PCR and DNA sequencing analysis. The cells(2×105) were injected into the thyroid gland of nude mice. The nude mice were executed at 4th, 12th week, and then their thyroid tumors were removed and weighed. The levels of thyroid hormone were detected using chemiluminescent immunoassay. Results Both TPC-1 and BHP2-7 cells were identified as RET/PTC1 rearrangement by real time-PCR, and the expression of RET/PTC1 rearrangement in BHP2-7 cell was higher than that of TPC-1 cell. BRAFV600E mutation was found in BHP5-16 cell by DNA sequencing analysis, but was not found in TPC-1 and BHP2-7 cells. There were different characteristics in three orthotopic nude model groups. Tumorigenic rates of TPC-1 and BHP5-16 groups were 100%, but the growth of tumor was more rapid in BHP5-16 group than that in TPC-1 group, with more weight tumor. The changes of thyroid hormone levels in BHP5-16 group and TPC-1 group were the same, which were normal at 4th week and sharply decreased at 12 th week(P<0. 05). However, the tumorigenic rate of BHP2-7 group was only 6. 25%. Compared with normal control group, there was no statistical difference in the levels of thyroid hormone in BHP2-7group(P>0. 05). Conclusions It showed difference in the orthotopic models of PTC cell lines of RET/PTC1 rearrangement and BRAFV600E mutation in nude mice. BRAFV600E mutation has obvious impacts on increasing tumorigenic rate and promotion of tumor growth in the orthotopic model. It should not be ignored that advanced thyroid tumor will lead to the destruction of thyroid function.

Background: Vocal cord polyps are commonly encountered in the otorhinolaryngology department. The risk of anesthesia is high in patients with large vocal cord polyps. Awake intubation with appropriate airway tools provides a favorable safety profile.Case: We present the case of a 60-year-old male patient who had been suffering from a large vocal cord polyp for 16 years. Electronic laryngoscopy revealed that the vocal cord polyp was approximately 1.5 cm in diameter. The polyp had a pedicle and demonstrated synchronous motion with respiratory excursion. It covered almost the entire glottic area during inspiration and moved away from the glottis during expiration. A Disposcope endoscope was used for awake tracheal intubation, and the surgery was completed successfully. Conclusions The Disposcope endoscope can be a useful option for awake orotracheal intubation in cases of anticipated difficult intubation and difficult facemask ventilation.

OBJECTIVETo compare the safety and efficacy between three-field lymphadenectomy and normative Ivor-Lewis two-field lymphadenectomy for thoracic esophageal squamous cell carcinoma METHODS: Clinical data of 375 patients with thoracic esophageal squamous cell carcinoma who underwent three-field lymphadenectomy(3FL) or Ivor-Lewis two-field lymphadenectomy(2FL, Ivor-Lewis) in Fudan University Shanghai Cancer Center during 2013 were retrieved and collected from electronic medical record system. Ninety-one patients received three-field lymphadenectomy (3FL group), including 16 cases of intra-cervical gastro-esophageal anastomosis and 75 cases of intra-thoracic gastro-esophageal anastomosis, while 284 patients received Ivor-Lewis two-field lymphadenectomy (2FL group) with all intra-thoracic gastro-esophageal anastomosis. Short-term outcomes were compared between two groups, including postoperative anastomotic leakage, pneumonia and respiratory failure, chylothorax, reoperation and 90-day death. Total harvested lymph nodes and positive lymph nodes in each group were also compared. A total of 338 patients were enrolled into survival analysis. Survival curve was presented by Kaplan-Meier method.

RESULTSAs compared to 2FL group, the 3FL group had significantly higher ratio of N3 patients [19.8% (18/91) vs. 5.3% (15/284), P=0.000], stageIII( patients [58.2%(53/91) vs. 43.0%(122/284), P=0.007], and upper thoracic cancer patients [12.1%(11/91) vs. 3.5%(10/284), P=0.027]; also the 3FL group had more harvested lymph nodes (40.1±14.6 vs. 25.3±9.4, P=0.000) and more positive lymph nodes (3.3±4.0 vs. 1.7±3.2, P=0.000). With respect to pneumonia and respiratory failure, chylothorax, reoperation and 90-day death, no significant differences were found between the group (P=0.447, P=0.751, P=0.678, P=0.685). The 3FL group had a significantly higher incidence of anastomotic leakage than 2FL group [7.7% (7/91) vs. 1.8% (5/284), P=0.011], while its incidence of intrathoracic anastomosis leakage was 4.0% (3/75), which was not significantly different with 1.8%(5/284) of 2FL group (P=0.372). Median follow-up was 33 months. Overall 1-, 2-, 3-year survival rates were 94%, 81% and 70%, while 1-, 2-, 3-year survival rates of 3FL group were 90%, 73% and 66%, of 2FL group were 95%, 84% and 72%, respectively, without significant differences between the two group(P=0.135). Further subgroup analysis showed that no significant differences of postoperative survival in stage I(, II( and III( patients were observed between the two groups (P=0.541, P=0.511, P=0.402), meanwhile no significant differences of postoperative survival in patients with metastasis and without metastasis were found between the two groups as well (P=0.985, P=0.233).

CONCLUSIONSThree-field lymphadenectomy can be performed with acceptable perioperative morbidity and mortality. The prognosis value of three field lymphadenectomy needs further investigation. Patients with thoracic esophageal squamous cell carcinoma may have favorable survival through normative Ivor-Lewis two-field lymphadenectomy.

Objective:To explore the effect of kangaroo mother care (KMC) on lactation, uterine involution of parturients and neonatal pain.Methods:A total of 200 parturients who gave birth at full term in our hospital from January 2019 to June 2019 and their newborns were selected as the research objects, they were randomly divided into control group and observation group of 100 pairs each. The control group received routine obstetric postpartum care and the observation group received KMC. The KMC cognition, postpartum lactation and uterine involution, neonatal pain during neonatal heel blood collection were compared between the two groups.Results:The cognition of KMC in the observation group was significantly better than that in the control group, and the difference was statistically significant ( χ 2 value was 24.700, P<0.01). The first lactation time of parturients in the observation group was (41.25±3.20) hours after birth, which was earlier than (54.17±2.20) hours in the control group, there was significant difference between the two groups ( t value was 2.378, P value was 0.019). The breast pain Ⅰ degree (20 cases), Ⅱ degree (56 cases), Ⅲ degree (24 cases) in observation group were significantly lighter than those in control group (62, 27, 11 cases respectively) 72h after delivery, the differences were statistically significant ( t value was 12.166, P value was 0.011). The parturients of sufficient lactation in the observation group (73 cases) were more than those in the control group (34 case),the differences was statistically significant ( χ 2 value was 30.570, P value was 0.000). The uterine fundus of the observation group decreased by (3.06±1.26) cm and (1.67 ±0.43) cm at 24h and 48h postnatally, which were better than those of the control group (1.97±0.92) cm and (1.23±0.18) cm,the differences were statistically significant ( t value was 3.162, P value was 0.002; t value was 2.689, P value was 0.009). In the process of heel blood collection after 72h of delivery in both groups, the pain scores of the observation group during and after blood collection were 4.92±0.33 and 2.37±1.27 respectively, which were lower than those of the control group (5.57±1.37 and 5.01±1.09), and the differences were statistically significant ( t value was 2.035, P value was 0.046; t value was 2.579, P value was 0.011). The heart rates of the observation group during and after blood collection were (121.36±22.13) and (142.55±23.91) beats/min, respectively, which were lower than (152.64±18.21) and (156.79±17.37) beats/min of the control group, the difference were statistically significant ( t value was 2.375, P value was 0.018; t value was 2.126, P value was 0.037). The blood oxygen saturation of the observation group during and after blood collection were 0.967 2±0.013 7 and 0.985 5 ±0.022 4 respectively, which were significantly higher than 0.891 7±0.116 5 and 0.914 5±0.137 8 of the control group ( t value was 2.036, P value was 0.046; t value was 2.017, P value was 0.047). Conclusions:The implementation of KMC can promote lactation, accelerate uterine involution, and relieve the pain of neonats during neonatal heel blood collection; Strengthening the health education of KMC can improve the cognition of parturients and their families about KMC, which has positive significance in promoting maternal and infant health and is worthy of clinical application.

OBJECTIVETo study the effect of Shexiang Baoxin pill (SBP) on the vascular endothelial function in patients with diabetes mellitus type 2 (DM2) complicated with angina pectoris.

METHODSTwo weeks after runin, according to the randomizing table, 111 patients were divided into two groups, the XBP group (56 patients) and the control group (55 patients, treated with delayed-released isosorbide mononitrate, DRIM), they were treated for 6 months. In the treatment period, the episodes of angina attack and condition of rescue medication were recorded in the daily card, and brachial arterial changes of endothelium-dependent relaxing function before and after treatment were measured by B-ultrasonography.

RESULTSComparison between the two groups in episodes of angina attack and rescue medication were insignificantly different. In the control group, the basal value of brachial arterial inner diameter before and after treatment was 3.68 +/- 0.56 mm and 3.70 +/- 0.58 mm respectively, those before and after responsive congestion was 5.44 +/- 0.81% vs 5.68 +/- 0.83%, and those before and after taking nitroglycerin was 19.8 +/- 4.9% vs 20. +/- 5.2%, all showed insignificant difference (P > 0.05). In the SBP group, the corresponding basal value was 3.73 +/- 0.62 mm vs 3.71 +/- 0.59 mm, and those after taking nitroglycerin 18.8 +/- 4.5 % vs 19.2 +/- 5.8%, also showed insignificant difference, but those before and after responsive congestion (5.69 +/- 0.79 % vs 9.56 +/- 3.82 %) did show significant difference (P < 0.01).

CONCLUSIONXBP could improve the vascular endothelial function in patients with DM2 complicated with angina pectoris.
