Objective To observe the effect of Dachengqi decoction combined with β-aescine on pulmonary function in patients with acute lung injury (ALI) after chest trauma.Methods Ninety-five patients with ALI after chest trauma admitted to the Department of Thoracic Cardiothoracic Surgery of Dingxi People's Hospital of Gansu from April 2013 to May 2016 were enrolled, and they were divided into a Dachengqi decoction group (47 patients) and a control group (48 patients) by random number table. The control group patients were treated with conventional therapy and β-aescine 0.4 mg/kg+ 10% Glucose (250 mL) intravenous drip, while the Dachengqi decoction group patients were additionally treated with Dachengqi decoction on the treatment of the control group (rhubarb 12 g, magnolia officinalis 24 g, fructus aurantii immaturus 12 g, mirabilite 9 g), one dose daily, taken twice in a day, once in the morning and once in the evening orally, both groups were treated for one week. Before and after treatment, the changes of esophageal pressure, respiratory dynamics, the indexes of pulmonary function and blood gas analysis were observed. Results Compared with those before treatment, the levels of plateau pressure (Pplat), mean airway pressure (mPaw), airway resistance (Raw) and arterial partial pressure of carbon dioxide (PaCO2) of the two groups after treatment were significantly reduced, but the levels of lower esophageal sphincter pressure (LESP), peak airway pressure (PIP), the first second forced expiratory volume (FEV1), forced vital capacity (FVC), peak expiratory flow rate (PEF), the mean maximum expiratory flow (MMEF), pulse oxygen saturation (SpO2), arterial partial pressure of oxygen (PaO2), oxygenation index (PaO2/FiO2) were all increased significantly; the changes of the above indexes in the Dachengqi decoction group were more significant than those in the control group [LESP (mmHg, 1 mmHg = 0.133 kPa):18.64±2.79 vs. 15.46±3.09, Pplat (cmH2O, 1 cmH2O = 0.098 kPa): 14.27±1.68 vs. 16.00±1.87, PIP (cmH2O): 40.23±5.03 vs. 32.19±4.45, mPaw (cmH2O): 8.57±0.67 vs. 9.41±1.23, Raw (cmH2O·L-1·s-1): 6.76±1.01 vs. 9.31±1.43, FEV1 (L): 1.73±0.27 vs. 1.46±0.25, FVC: (3.95±0.51)% vs. (3.30±0.46)%, PEF (L/s): 3.81±0.47 vs. 3.11±0.38, MMEF (L/s): 0.93±0.16 vs. 0.77±0.12, SpO2: 0.96±0.06 vs. 0.91±0.05, PaO2 (mmHg): 97.82±10.13 vs. 74.73±8.02, PaCO2 (mmHg): 36.49±4.28 vs. 47.13±5.46, PaO2/FiO2 (mmHg): 362.47±20.82 vs. 259.79±17.61, allP < 0.05]. Conclusion Dachengqi decoction combined with β-aescine can reduce the respiratory intensity of patients with ALI after chest trauma and improve the lung function and blood oxygen level.

AIM: To investigate the roles of protein kinase C (PKC) and extracellular signal-regulated kinase (ERK) in delayed protection mechanism of anoxia preconditioning (APC) in rat cardiomyocytes.METHODS: The anoxia/reoxygention (A/R) injury, APC and PMA (an activator of PKC) preconditioning models were established in cultured neonatal rat cardiomyocytes and the effects of PKC and ERK blokers on the models were observed. ERK activity was assayed at 10 min after preconditioning in every group. The cellular MDA, SOD, cell viability and LDH release were measured at the end of the study. RESULTS: Compared with the cardiomyocyte in A/R group, the percentage of viable cells and SOD activity were greatly increased (P

Objective:To evaluate the clinical significance of expression of proliferation cell nuclear antigen(PCNA),P16 and P27genes in adenoid cystic carcinoma of salivary glands.Methods:The expressions of PCNA,P16and P27were detected by immunohistochemical staining (SP)in 55 patients with adenoid cystic carcinoma of salivary glands.Results:The higher and lower expressions of PCNA were 45.5%(19/55) and 65.5%(35/55) respectively;of P16 were 45.5%(25/55) and 54.5%(30/55)respectively.And the positive and negative expressions of P27 were 34.5%(19/55) and 65.5%(36/55),respectively.The correlation of expression of PCNA gene with local recurrence and tumor site showed significant (P=0.0317,P=0.0186);but the expression of P16was no any significant correlation in all of the variables.The expression of P27 was significant on the regional lymph node metastaisis (P=0.0083).When higher expression of P16was 45.5%(25/55),the P27positive expression was 56.0%(14/25),which showed a significant positive correlation (P=0.0025).Conclusion:In adenoid cystic carcinoma of salivary glands,the PCNA gene should be one of the biological target predicting local recurrence,and P27gene should be one of the biological target justifying regional lymph node metastasis.

OBJECTIVE To investigate the characteristics of hypopharyngeal carcinoma detected by narrow band imaging(NBI)endoscopy and evaluate the value of NBI in the early diagnosis of hypopharyngeal carcinoma. METHODS Between December 2008 and July 2009,a total of 46 consecutive patients with hypopharyngeal squamous cell carcinoma were enrolled in this study. High performance endoscopic system equipped with the white light mode and NBI mode was introduced in the examination of pharynx and larynx. The quality of visualization of morphologies of epithelial capillary and demarcation line of each lesion under NBI view was evaluated in comparison with conventional white light endoscopy. RESULTS Among the 46 patients,a total of 86 lesions were detected. The notable characteristic of hypopharyngeal squamous cell carcinoma is the well demarcated brownish area and scattered brown dots. The NBI laryngoscope could provide better visualization of morphologies of epithelial capillary and demarcation line in superficial carcinoma of hypopharynx than the white light mode(P

Objective To evaluate the clinical outcomes of internal fixation with extra-articular distal humerus locking compression plate (LCP) for the treatment of mid-distal humerus diaphyseal fracture.Methods From December 2012 to December 2016,a cohort of 22 patients with mid-distal humerus shaft fracture were treated by open reduction and internal fixation using extra-articular distal humerus LCP.They were 14 males and 8 females with an average age of 42.7 years (range,from 18 to 86 years).According to AO classification,there were 13 cases of type 12-A,7 cases of type 12-B,and 2 cases of type 12-C.The surgical time,intra-operative blood loss and hospital stay were recorded.The clinical outcomes were evaluated by the Mayo elbow performance score (MEPS) at the last follow-ups.Results Surgical time ranged from 46 to 95 minutes with an average of 57 minutes.The average blood loss was 220 mL (range,from 150 to 400 mL).The average hospital stay was 10.5 days (range,from 9 to 13 days).The mean follow-up was 23.8 months (range,from 6 to 48 months).Bone union was achieved in 21 cases after an average of 4.6 months (range,from 3 to 9 months),and one patient experienced bone non-union which was uneventfully healed after secondary auto platelet rich plasma (PRP) graft management.The average MEPS elbow performance score was 88.2,resulting in 16 excellent,4 fine and 2 fair cases (excellent and fine rate:90.9％).Conclusions Since extra-articular distal humerus LCP can provide stable internal fixation,facilitating early postoperative rehabilitation,it may be considered an effective alternative osteosynthesis for mid-distal comminuted humeral diaphyseal fractures.

OBJECTIVETo investigate the prognostic factors relevant to sudden sensorineural hearing loss.

METHODSThe internationally accepted standardized clinical research methods, unified design, and unified program were adopted to conduct the prospective clinical multi-center study. The sudden deafness patients between 18 to 65 years old, with the course of this disorder less than two weeks, and without any medical treatments were collected, and then, divided into four types according to the hearing curve: type A, acute sensorineural hearing loss in low tone frequencies; type B, acute sensorineural hearing loss in high tone frequencies; type C, acute sensorineural hearing loss in all frequencies; and type D, total deafness. The factors, in terms of age, gender, type of initial audiogram, time delay before the first visit, and severity of hearing loss, were included in the analyses.

RESULTSA total of 1 024 cases with single side sudden deafness were collected in the study from 33 hospitals in China from August 2007 to October 2011, inclusive of for 492 males (48.05%) and 532 females (51.95%). The average age was (41.2 ± 12.8) years old. There were 553 cases (54.00%) in left ear, and 471 cases (46.00%) in right ear. The curative effects of different types were shown as follows: the type in low tone frequencies had the highest rate of 90.73%, the type in all frequencies was 82.59%; the type of total deafness was 70.29%; and the type in high tone frequencies had the lowest rate of 65.96%. It had significant difference of the effective rate between different types (χ(2) = 231.58, P = 0.000). Age, time delay before first visit, and severity of initial hearing loss were significantly correlated with hearing improvement.

CONCLUSIONSInitial audiogram of SSNHL might predict hearing recovery. The young in age and a short time delay before starting treatment are positive prognostic factors for hearing recovery in SSNHL. The initial severity of hearing loss is negative prognostic factor of hearing recovery.

The 2030 Immunization Agenda of the World Health Organization （WHO） states that everyone in the world should fully benefit from vaccines to achieve good health and well-being. With the ever-changing disease spectrum and the improvement of residents' health literacy， relying solely on vaccines included in the National Immunization Program （NIP） is insufficient to meet the current requirements for disease prevention and control. Non-NIP vaccines play an important role in meeting people's diverse needs. Vaccine hesitancy is a global issue and an important factor affecting vaccine uptake. By reviewing relevant studies on vaccine hesitancy in recent years， this paper summarized different vaccination situations， current situation of vaccine hesitancy， measuring tools of vaccine hesitancy， and major influencing factors. It aims to provide references for the development of scientific and effective vaccine education strategies， which can increase public knowledge and understanding of vaccines， enhance healthcare professional's willingness and behavior in recommending vaccines， improve public vaccine literacy， and reduce vaccine hesitancy. At the same time， the supervision and guidance of media discourse should be strengthened to enhance the protective role of non-NIP vaccines in immunization barriers.
