Objective To investigate the efficacy of conservative treatment with laparoscopy for patients with ectopic pregnancy.Methods From January 2000 to December 2005,76 patients with ectopic pregnancy received conservative treatment by laparoscopy in our hospital.The data of the patients were analyzed retrospectively.Results In this series,fenestration of the Fallopian tube was performed on 42 cases,salpingostomy on 21,fimbrial expression on 8,and segmental resection and end-to-end anastomosis on 5.Salpingography showed that the Fallopian tube was patent after the operation in all of the patients.The mean operation time was(58.5?19.4) minutes(ranged from 35 to 105).The serum level of ?-hCG decreased to a normal range in 3 weeks postoperation.Follow-up was available in 61 cases for 1 year,during which 35 of the cases(57.4%,35/61) had intrauterine pregnancy;2(3.3%) had spontaneous abortion,and 2(3.3%) showed ectopic pregnancy;the other 22(36.1%) had no pregnancy.Conclusions Conservative treatment by laparoscopy is safe and effective for ectopic pregnancy.To avoid repeated ectopic pregnancy,?-hCG monitoring after the operation is necessary.

Aim To observe whether the inhibition of PI3K/PKB signal pathway by LY294002[PI3K pathway inhibitor] could improve the sensitivities of human gastric carcinoma cell line SGC7901 and SGC7901/VCR to anti-cancer drugs.Methods The sensitivities of SGC7901 and SGC7901/VCR to chemotherapeutic drug VCR were detected by MTT.The MDR1 and XIAP mRNA expression levels were evaluated by semi-quantitative RT-PCR,and their protein levels were detected by immunocytochemistry.The PKB and phospho-PKB protein levels were detected by Western blot and the apoptosis ratio was detected by flow cytometry.Results 2?10-5mol?L-1LY294002 enhanced the sensitivities of SGC7901 and SGC7901/VCR cells to VCR(P

Objective To explore the effect of the unilateral lumbar anesthesia by hypobaric bupivacaine and general anesthe‐sia in elderly hip replacement and their influence on the stress response .Methods Forty elderly patients undergoing hip replace‐ment in our hospital from December 2013 to November 2014 were selected and randomly divided into the unilateral lumbar anesthe‐sia group and general anesthesia group according to the random number table ,20 cases in each group .Venous blood was collected to determine the levels of blood sugar ,serum catecholamine(CA) and cortisol(CORT ) at 10 min before anesthesia(T0 ) ,end of surgery (T1 ) and at postoperative 24 h(T2 ) .MAP ,HR ,SpO2 ,intraoperative adverse reactions and postoperative related complications were recorded at each time point ,and the comparative analysis was performed .Results All patients successfully completed surgery and the anesthetic effect was satisfied .The occurrence rates of intraoperative hypotension ,hypertension and bradycardia in the unilateral lumbar anesthesia group were lower than those in the general anesthesia group ,the differences had statistical significances (P>0 .05) .HR and MAP at T1 in the two groups were reduced ,but the differences between the two groups were no statistical signifi‐cance(P>0 .05);the levels of GLU ,CORT and CA were increased ,moreover the differences between the two groups were statisti‐cally significant(P<0 .05) .SpO2 at T2 in the general anesthesia group was obviously lower than that in the unilateral lumbar anes‐thesia group ,while CORT was higher than that in the unilateral lumbar anesthesia group ,the differences were statistically signifi‐cant(P<0 .05) .The occurrence rates of postoperative nausea and vomiting ,sore throat ,dizziness ,drowsiness and pulmonary infec‐tion in the unilateral lumbar anesthesia group were lower than those in the general anesthesia group ,the differences were statistical‐ly significant(P<0 .05) .Conclusion The unilateral lumbar anesthesia by using hypobaric bupivacaine and general anesthesia all could offer better anesthetic effect .The unilateral lumbar anesthesia by using hypobaric bupivacaine can effectively regulate the stress response in elderly patients with hip replacement .

Objective To analyze and discuss the negative effects of atomization inhalation in mechanical ventilation patients in intensive care unit. Methods A retrospective study of all the mechanical ventilation patients in the general ICU of our hospital was carried out from Aprilto December 2015. The risk of multidrug-resistant organisms(MDROs)colonizationin the lower respiratory tract and ventilation associated pneumonia(VAP)in mechanical ventilation patients were analyzed. Results A total of 922 patients were monitored, 160 of whom had atomization inhalation, 92 for MDROs colonizationin the lower respiratory tract and 18 for VAP. The rates ofatomization inhalation in patients with and without MDROs colonizationin the lower respiratory tract were 30.4%(28/92)and 15.9%(132/830)with statistical difference (χ2=12.193, P=0.000). And those in patients with and without VAP were 50.0%(9/18) and 16.7%(151/904), with statistical difference (χ2=11.420, P=0.000). Atomization inhalation was the independent risk factor both of MDROs colonizationin the lower respiratory tract(OR=1.917, 95%CI1.163-3.159, P=0.011) and VAP(OR=4.613, 95%CI 1.773-12.002, P=0.000) in mechanical ventilation patients. Conclusions Atomization inhalation may increase the risk of MDROs colonizationin the lower respiratory tract and VAP in mechanical ventilation patients. Thus unnecessary and too frequent operations of atomization inhalation should be decreased.

Cryogel is a kind of elastic, spongy hydrogel prepared via addition polymerization from monomers or cross-linking reaction from a polymer at a temperature lower than the freezing point of the solvent. Cryogel has been principally used in molecular imprinting cryogel based solid phase extraction in the field of analytical chemistry, which combines both the advantages of high selectivity of the molecular imprinting and the porous structure, high throughput of a cryogel. Molecular imprinting cryogel can be used as the stationary phase in a packed column, a monolith column, or the adsorbent in a separation membrane. A variety of molecules can act as template molecules, including small molecules, macromolecules, a certain fragment of a macromolecule, and even an inorganic ion. Both a simple template and a complex template can be used. When employing more than a molecule ( or an ion) as templates simultaneously, the method is termed as Mixed template. While high abundance components of a complex sample act directly as mixed template, we name the method as Pending template. Further, while an analogue, an isotopic label, or a fragment of the target substance acts as a template, the method is defined as Dummy template. However, the research on cryogel is insufficient and the application of the cryogel is narrow hitherto.

Though parched Chinese herbal medicines contain less effective or index components, their pharmacological actions do not reduce or even become improved to some extent. However, the current studies related to material basis could not explain the changes in property, flavour and efficacy of parched Chinese herbal medicines. Meanwhile, due to the lack of objective and specific evaluation indexes, the quality evaluation could not reflect features of parched Chinese herbal pieces. Therefore, how to break the bottleneck for the studies on parched Chinese herbal pieces, make further innovation and conduct in-depth studies on the material basis of parched Chinese herbal medicines are common problems that medical scholars are facing. According to the findings in the previous studies, the author proposed to explain the material basis of parched Chinese herbal medicines by studying Maillard reaction and establish specific quality evaluation indexes according to the features of parched Chinese herbal pieces, and conducted relevant studies.

ObjectiveTo explore the application of diffusion-weighted magnetic resonance imaging (DWMRI) in precise radiotherapy of esophageal carcinoma.MethodsThirty-seven patients with biopsy proven esophageal cancer from March 2010 to January 2011 were included.To delineate the gross tumor volume (GTV) using CT and DWMRI images,each patient was examined by DWMRI and CT scan using the same position before radiotherapy.To compare the maximum diameters and volumes of tumor between CT and DWMRI. The tumor lengths measured by esophagogram,esophagoscope,CT and DWMRI were compared.ResultsTumor lengths under esophagogram,esophagoscope,CT and DWMRI were 5.70 cm,6.06 cm,7.97 cm and 5.79 cm respectively. The lengths between CT and esophagogram,CT and esophagoscope,CT and DWMRI had statistical significance respectively (F=4.88,P=0.003).The maximum diameters of tumor shown on CT and DWMRI were 3.79 cm and 3.81 cm respectively ( t =-0.32,P=0.751 ).The GTV were 45.75 cm3 and 38.05 cm3 in CT and DWMRI respectively (t=5.30,P =0.001 ).53 lymph nodes were assessed positive on both CT and DWMRI.DWMRI excluded 25 positive lymph nodes assesed by CT; also confirmed 15 negative lymph nodes excluded by CT,6 of which were paraesophageal lymph nodes.The addition of DWMRI information altered the clinical stage in 6 patients.ConclusionsTumor lengths measured on DWMRI and esophagogram had the optimal approximation.It was easy to find paraesophageal lymph nodes via DWMRI.With the addition of DWMRI information,the target range and clinical stage were alerted in some patients.
