Objective To learn the current anesthesiologists deployment at the hospital,and to figure out how to measure anesthesiologists deployment.Methods Existing data and expert consultation were used to obtain various indicators,and the current anesthesiologists deployment was analyzed,calculating with the formula the needed number of anesthesiologists.Results Despite the rising demand and resource utilization,anesthesiologists were found in obvious shortage at the hospital.The number of anesthesiologists needed was calculated as 101.4,with a vacancy of 11.4.Conclusion The national health authorities were recommended to revise the standard of anesthesiologists deployment at hospitals.

Professor LU Zhi-zheng, one of the first traditional Chinese medicine masters, is good at using tenuifoliain clinical practice, which often brings unexpected surprises. Lu said, tenuifolia is a mild herbal medicine with the nature of upward dispersion and outward penetration but not dryness. Tenuifolia has the following functions: making people conscious, relieving sore throat, diverging incubated diseases, regulating functional activities of qi, sending up Yang, dispelling wind evil and eliminating dampness, and activating collaterals to relieve pain. When well used, it will not only enhance the effect of monarch drug, but also restrict the impetuosity nature in a prescription, achieving better efficacy.

Objective The aim of this study is to establish a practical VX2 tumour model less than or equal to 10 mm from large blood vessel(as standard) for HIFU ablation .Methods 15 New Zealand rabbits were involved ,VX2 tumour blocks were inoculated near postcava through spine path ,and tumour rate was observed two weeks later by anatomy and MRI .Results Three experimental rabbits did not survive ,all the rest of the 12 into the tumour ,assembly tumour rate was 100% (12/12);The tumour rate reaching the standard accounted for 75% (9/12) ,the average distance between the tumour and the inferior vena cava was (5 .6 ± 3 .4)mm . Conclusion It is feasible to establish the VX2 tumor model less than or equal to 10 mm from large blood vessel through spine path .

ObjectiveTo investigate the protective effect of pyrroloquinoline quinone (PQQ) on damage of hippocampal neurons induced by NMDA.MethodsHippocampal neurons were cultured in vitro and NMDA was used to induce neurotoxicity 8 d after, while PQQ were used or not before. The metamorphosis of hippocampal neurons was observed under the microscope. Intracellular calcium levels was measured by confocal laser microscopy. ResultsThe intracellular Ca2+ level increased rapidly after exposure to 0.1 mmol/L NMDA and resulted in neuronal necrosis and apoptosis. Otherwise, pretreatment of the cultured neurons with PQQ reduced the increase of the intracellular Ca2+ level and the neuronal necrosis or apoptosis induced by NMDA.ConclusionPQQ can protect hippocampal neurons from damage induced by NMDA.

Objective To summarize our experience in the management of cardiopulmonary bypass (CPB) with deep hypothermic circulatory arrest (DHCA) during aortic arch surgery.Methods From March 2007 to May 2010,58 consecutive patients,including 24 urgent and 34 selective operations underwent aortic arch surgery.Thirty-nine hemiarch and 19 total aortic arch replacement operations were performed.CPB was established by perfusion through femoral artery (42 cases) and right subclavian artery (RSA) ( 16 cases),of which 4 cases were carried out with antegrade cerebral perfusion (ACP).Results The mean CPB time was ( 208.88 ± 136.45 ) min.The mean cerebral circulation arrest was ( 27.36 ± 11.50 ) min.Nasopharyngeal and rectal temperature were ( 16.01 ±2.67)℃ and ( 19.72 ±2.13)℃ respectively before DHCA was initiated.The mean times for cooling and rewarming were ( 50.91 ± 16.89) min and ( 88.97 ± 43.68 ) min.The mean time of intubation was (56.70 ± 45.19 ) h.The time in ICU was ( 5.68 ± 5.31 ) d,and the time of hospitalization was (30.11 ± 22.27 ) d.Acute renal failure,hypoxemia,and paraplegia occurred post-operatively in 4,19,and 2 patients,respectively.Four patients died post-operatively with a mortality of 6.90％.Compared with those received hemiarch replacement operation,the patients received total aortic arch replacement had statistically longer time of CPB([262.16 ±219.97]min vs [182.92 ±53.81] min,t =2.14,P ＜0.05),cerebral circulatory arrest ( [30.47 ± 15.86 ] win vs [25.85 ± 8.48 ] min,t =2.40,P ＜ 0.05 ),rewarming ( [110.00 ± 68.66 ] min vs [78.72 ± 17.31 ] min,t =2.69,P ＜ 0.05 ),and intubation ( [93.95 ± 131.89 ] h vs [38.08 ± 30.70 ] h,t =2.50,P ＜ 0.05 ).There was no significant difference in the times of these procedures between emergency surgery group and elective surgery group,between RSA and femoral artery cannulation groups.Conclusion It is crucial that the cooling and re-warming procedures during aortic arch surgery should be carried out slowly,gradually,and completely when DHCA was adopted alone.conclusion through right axillary artery or RSA was preferred for ACP,in order to accomplish the body circulation arrest at a relative high temperature,to shorten the CPB time,and to alleviate potential harmful effects of hypothermia.Meticulous management of CPB is one of the most important measures to improve the patients' outcome.

· AIM: To search an easy and simple way for intraocular implantation after the eye evisceration.· METHODS: Fifteen healthy New Zealand rabbits were divided into 5 groups according to the sacrifice time, and each group included 3 rabbits; the left eye received the injection of polymethyl methacrylate (PMMA) bone cement (2g per mL), while the right eye served as control. Under general anesthetia, a 3mm incision was made on the sclera,and the eye contents and pigment tissues were extruded out with fingers. Then, PMMA bone cement (2g per ml) was injected through the scleral incision. Both the operated eye and control eye of the rabbits were enucleated and weighed,The reaction of the operated eye (macroscopically and histopathologically) was noted at frequent interval. The obtained data were then analyzed with ANOVA (SPSS11.5).· RESULTS: There was swelling of eyelids and conjunctiva at the early time after the injection, but no significant difference between the weight of the left and right eyes was noted,Histopathologic examination showed scleral and other tissues necrosis at early period, and then the tissues reaction turned into a great deal of cell proliferation and finally into extensive fibro-connective tissues. Three months after the operation,neovascularization was observed in the cornea of the operated eyes. Histopathologic examination showed formation of fibro-membrane around the intraocular implant,and disappearance of the inflammation.· CONCLUSION: The method of injecting PMMA bone cement (2g per ml) to form an intraocular implant is quite simple and economical; this method is also easy to use clinically.

[ABSTRACT]OBJECTIVEThe purpose of this study was to analyze the screened miRNAs related to the chemosensitivity for the TPF regimen of hypopharyngeal squamous cell carcinoma by miRNA array, and provide a set of miRNAs that may be useful for the development of novel diagnostic markers and more effective therapeutic strategies from the screened miRNAs.METHODSA total number of 21 patients who underwent TPF induction chemotherapy for primary hypopharyngeal squamous cell carcinoma were recruited for miRNA array analysis. 12 patients are sensitive to chemotherapy, and 9 patients are not. Moreover, the selected putative regulated miRNAs were also validated by RT-PCR in another 24 patients (14 patients are sensitive to chemotherapy, and others are not).RESULTSThere were 24 miRNA significantly differencial to the sensitivity to chemotherapy, and 6 miRNAs were up-regulated in the TPF group while 18 miRNA were down-regulated (P<0.05). To identify typical miRNA, mirfocus 3.0 database selected four miRNAs hsa-miR-211-3p, hsa-miR-4253, hsa-miR-4443, and hsa-miR-193b-3p, which were significant down-regulated in TPF-sensitive group. QRT-PCR further validated that only three miRNA (hsa-miR-4253、hsa-miR-4443、hsa-miR-193b-3p) were under-expressed in TPF-sensitive group of another 24 tissue samples (P<0.05).CONCLUSIONMiRNA hsa-miR-193b-3p, hsa-miR-4253, hsa-miR-4443 were identified in TPF-sensitive tissues by microarrays, and further validated by RT-PCR. These down-regulated miRNAs may act as novel biomarkers to classify TPF sensitivity of hypopharyngeal squamous cell carcinoma patients and will contribute to the understanding of the molecular basis of the chemosensitivity in the disease.
