Objective To analyze the differences of video laryngoscope, direct laryngoscopy and fibreoptic bron﹣choscope nasal intubation on hemodynamics, inflammatory and stress response. Methods 117 patients underwent surgery from November 2013 to March 2015 were chose as research subjects and randomly divided into video laryn﹣goscope group, direct laryngoscopy group, fiberoptic bronchoscope group based on different cannula enrolled way. Then compared the hemodynamics, inflammation, stress level after intubation among the three groups. Results Com﹣pared with the T0, the three groups patients' systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), C-reactive protein (CRP), interleukin -6 (IL-6), tumor necrosis factor (TNF-α), norepinephrine (NE), plasma cortisol (Cor), angiotensinⅡ(ATⅡ) differences had no significant difference (P>0.05);compared with direct laryn﹣goscopy group, video laryngoscope group, fiberoptic bronchoscope group patients' T1, T2, T3 SBP, DBP, HR, CRP, TNF-α, IL-6, NE, Cor, ATⅡ levels were lower; compared with the video laryngoscope group, optical fiber bron﹣choscopy group patients SBP, DBP, HR, CRP, TNF-α, IL-6, NE, Cor, ATⅡ low levels at T1, T2, T3 were lower (P<0.05). Conclusions Fibreoptic bronchoscope nasal intubation has less influence on patients, will not cause severe stress and inflammatory response, it is one of the ideal instrument anesthesia induction intubation.

Objective To explore the possible effects of methyl methanesulfonate sensitive 2(MMS2)in the process of angiotensin Ⅱ inducing differentiation of neural stem cells (NSCs) into dopaminegic phenotype neurons. Methods NSCs were isolated from the brain of newborn rats and were cultured in the serum-free medium.Identification of neural precursor cells was done by Nestin immunocyt ochemical staining. Then the second generation of NSCs was divided into the following six groups: A, control; B, AⅡ; C, AT1 antagonist ZD7155; D, ZD7155+AⅡ; E, AT2 antagonist PD123319; F, PD123319+AⅡ. The detection of expression of MMS2 and TH mRNA level was done by real-time PCR. The silence of the expression of MMS2 in NSCs was brought about via the transfection of MMS2-siRNA, and then the NSCs were induced to differentiate into dopaminegic neurons. The expression of TH mRNA level in the cells of the groups after transfection was detected by real-time PCR. Results Nestin-positive cells were observed in suspended growth in the medium.Real-Time PCR revealed that the MMS2 and TH mRNA expression of group B and D were significantly higher than that of the control group(P<0.05), There was no significant difference in MMS2 and TH mRNA expression between group C, E, F and the control, respectively. Conclusion AⅡ increased the expression of MMS2 mRNA in NSCs and induced the differentiation of NSCs into DA neurons via AT2 recepter. MMS2 may play important roles in the process of angiotensin Ⅱ inducing NSCs to differentiate into dopaminergic neurons.

Objective To investigate whether the change of cardiac output (CO) with bed head raising (BHR) combined with passive leg raising (PLR) can be used to assess volume overload in critical patients.Methods A prospective observational diagnostic trial was designed. The patients who underwent fluid resuscitation 6 hours or more, and admitted to intensive care unit (ICU) of Meizhou People's Hospital in Guangdong Province from January to December in 2016 were enrolled. Volume overload were identified with the criteria including the increasing of pulmonary rales, the higher levels of N-terminal brain natriuretic peptide (NT-proBNP) and new pulmonary exudates in chest radiograph. CO and heart rate (HR) were monitored with impedance cardiography at supine position and BHR by 30°(BHR30), 60° (BHR60), and PLR in all patients. The changes of CO (?CO30,?CO60,?COPLR) and HR (?HR30,?HR60,?HRPLR) were calculated at different positions. The receiver operating characteristic curve (ROC) was used to evaluate the predictive values of?CO30,?CO60 and combination of?CO60 and?COPLR on volume overload.Results A total of 62 patients were enrolled in this study, with 44 males and 18 females, age of (58.9±15.9) years, a body mass index of (22.7±2.4) kg/m2, and an acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score of 18.7±4.4. The CO of 32 patients with volume overload was significantly increased at BHR30 or BHR60 compared with supine position [?CO30 was (14.5±11.5)%,?CO60 was (26.9±17.5)%, bothP< 0.01], and the?CO60 was increased more than the?CO30 (P < 0.01);while CO was slightly decreased after PLR,?COPLR was (-8.4±11.3)% (P > 0.05). There was no consistent change of CO at BHR30 or BHR60 compared with supine position in 30 patients without volume overload,?CO30 was (-3.4±9.1)% (P < 0.05),?CO60 was (-2.4±14.0)% (P > 0.05), while CO was significantly increased after PLR,?COPLR was (12.4±11.3)% (P < 0.01). There was no significant change of HR after BHR and PLR in patients with volume overload and non volume overload. ROC curve showed that when the cut-off value of ΔCO30≥3.3%, the area under ROC curve (AUC) was 0.903±0.039, the sensitivity was 90.6%, the specificity was 80.0%, and the accuracy was 85.5% for predicting volume overload; when the cut-off value of ΔCO60≥5.6%, the AUC was 0.911±0.036, the sensitivity was 96.9%, the specificity was 73.3%, and the accuracy was 85.5% for predicting volume overload. If volume overload was assessed by the increase of ΔCO60 combining with the decrease of ΔCOPLR, the AUC was 0.928±0.034, the optimal cut-off value for the new combined predictive indicator in predicting volume overload was -0.008, and the sensitivity, specificity, accuracy was 96.9%, 83.3%, 90.3%, respectively, and its evaluation effect is better than the use of ΔCO30 or ΔCO60 alone.Conclusion The change of CO with BHR combined with PLR can be used to accurately evaluate volume overload in patient with critically illness.

Objective To observe the levels of serum VEGF in different molecular subtypes of breast cancer and explore its relationship with response to neoadjuvant chemotherapy. Methods Levels of serum VEGF in 110 cases with breast cancer underwent neoadjuvant chemotherapy were detected by ELISA prior to and after 3 cycles of neoadjuvant chemotherapy. Clinical response to neoadjuvant chemotherapy was evaluated by physical examination and ultrasonography. Results Levels of serum VEGF were significantly increased in breast cancer patients with≥4 lymph node metastasis than those with < 4 lymph node[(307.31 ± 101.42) pg/mL vs. (170.16 ± 73.07) pg/mL,P = 0.017]. Patients with positive HER-2 status had significantly higher levels of serum VEGF than those with HER-2 negative status [(235.15 ± 88.42 ) pg/mL vs. (179.82 ± 69.90) pg/mL, P = 0.024]. No significant difference was observed among age , menopausal status and hormone status. In patients with neoadjuvant chemotherapy of cCR and Cpr,the mean levels of serum VEGF were (205.75 ± 78.12) pg/mL and (226.04 ± 89.04) pg/mL, respectively. After 3 cycles of chemotherapy, levels of serum VEGF decreased to (145.15 ± 67.08) pg/mL and (161.27 ± 93.57) pg/mL. There was significant difference between two groups (P=0.009,0.014). In patients with SD or PD response, no significant difference was observed between levels of serum VEGF before and after chemotherapy (P = 0.577). Conclusions Levels of serum VEGF in breast cancer correlate with lymph nodes metastasis and HER-2 status and may decrease after neoadjuvant chemotherapy. However,whether or not the levels of serum VEGF can be used as a biomarker for response to neoadjuvant chemotherapy needs more further studies.

BACKGROUND:The ankle is one of the most important joints of human body. Medial maleolar fractures are very common, and there are lots of surgical methods to treat it. A traditional approach is open reduction and internal fixation. As views changed, percutaneous cannulated screw internal fixation become increasingly popular, but various clinical studies are stil needed to analyze the efficacy of these two methods. OBJECTIVE:To compare the recovery of joint function after medial maleolus fracture repaired by open reduction and internal fixation and percutaneous cannulated screw fixation. METHODS:A total of 63 cases of medial maleolus fracture, who were treated in the Department of Orthopedics, People’s Hospital of Xinyi City from March 2009 to March 2013, were enroled. According to repair plan, they were divided into two groups: open reduction and internal fixation group (n=29) and percutaneous cannulated screw fixation group (n=34). Ankle function was assessed in accordance with Kofoed ankle score standard on admission and at 3 months after repair. RESULTS AND CONCLUSION:The patients were folowed up for 3 to 12 months. Among 29 cases in the open reduction and internal fixation group, the wound was healed at grade A in 27 cases and at grade B in 2 cases; 29 cases were reset, and no poor reduction was found. In the percutaneous cannulated screw fixation group, 34 cases had healing at grade A, with the presence of good reduction. Al patients experienced bone union, and no infection appeared. In accordance with Kofoed score, at 3 months of folow-up, the satisfaction rate was 97% in the open reduction and internal fixation group, and 100% in the percutaneous cannulated screw fixation group. These data suggest that both open reduction and internal fixation and percutaneous cannulated screw fixation for medial maleolus fracture obtained positive effects, but percutaneous cannulated screw fixation showed smal surgical trauma, which could reduce the rate of infection and contributed to early functional recovery of ankle joint.

Bipolar disorder （BD） is a serious chronic emotional disorder with a high suicide rate and a common psychiatric disease. Traditional Chinese medicine （TCM） treatment based on syndrome differentiation of BD has unique advantages and good safety， which is expected to become a breakthrough in the treatment. Based on Expert Consensus on TCM Syndrome Differentiation Criteria for Bipolar Disorder by Professor Yin Dongqing and Professor Jia Hongxiao， this study collated the treatment protocols of BD with various syndrome types according to Meta-analysis of the existing literature in the database and evaluated the evidence level according to the evidence evaluation standard issued by the US Agency for Healthcare Research and Quality （AHRQ）. （1） Depression attack. ① Liver depression and spleen deficiency syndrome： Xiaoyaosan pills or Shugan Jieyu capsules， ② Phlegm dampness and spleen stagnation syndrome： Wendantang modified with Tianwang Buxindan， ③ Heart and spleen deficiency syndrome： Jiuwei Zhenxin Granules or DANG's Ganmai Dazhaotang， ④ Fire heat and internal depression syndrome： Danzhi Xiaoyaosan Granules or Chaihu Longgu Mulitang， ⑤ Liver and kidney deficiency syndrome： JIANG's Buganshen Decoction. （2） Mania episode. ① Heart and liver fire hyperactivity syndrome： Zhengan Ningshen Formula， ② Phlegm heat harassing spirit syndrome： Huatan Xiehuo Dingshen decoction， Lianzhi Tongqiao Anshen decoction， Qingshen Dingkuang decoction or Qingshen Xingnao decoction， ③ Liver and gallbladder dampness-heat syndrome： Longdan Xiegantang. （3） Other syndrome types. ① Liver qi stagnation syndrome： modified Tongqiao Huoxue decoction， Shengyang Yiwei Acupuncture， ② Deficiency of kidney yang syndrome： Jingui Shenqitang， ③ Phlegm accumulation and blood stasis syndrome： modified Tongqiao Huoxue decoction， ④ Qi and Yin deficiency， stagnation of blood stasis syndrome： Xinnaoxin pills， ⑤ Syndrome of blood deficiency generating wind and fire heat harassing spirit： Fangji Dihuangtang.

Bipolar disorder （BD） is considered to be mainly related to qi， phlegm， fire and deficiency. Binding constraint of liver qi is the initial cause， while phlegm and qi interact obstruction as well as phlegm and fire interact binding is the key pathogenesis of the transformation between depression and mania， and deficiency of both qi and yin is the main reason of the protracted course of disease. In clinical practice， BD is divided into binding constraint of liver qi pattern， phlegm and qi interact obstruction pattern， phlegm and fire interact binding pattern， and deficiency of both qi and yin pattern， which can be treated with Jinyu Shugan Powder （金玉疏肝散）， Kaiyu Wendan Decoction （开郁温胆汤）， Qingxin Huatan Decoction （清心化痰汤）， and Baihe Shengmai Beverage （百合生脉饮） in their modifications respectively； moreover， Guanye Jinsitao （Herba Hyperici Perforati） is usually used to rectify qi， relieve phlegm and clear heat. It is also suggested to put focus on the prevention and treatment of qi， phlegm and heat simultaneously， and modify the medicinals flexibly in accordance with the pathogenesis evolution and the abnormal exuberance.
