Objective To investigate the value of fast track surgery (FTS) principles in the perioperative management of liver cancer patients after hepatectomy.Methods Forty patients with primary liver cancer who were admitted to the First People's Hospital of Qinzhou from September 2011 to July 2013 were enrolled in this prospective study.All the patients were randomly divided into the FTS group (20 patients) and the control group (20 patients) according to the random number table.The perioperative management of patients in the FTS group was guided by the FTS principles,patients in the control group were managed with traditional methods.The intraoperative condition,time for portal occlusion,operation time,volume of intraoperative blood loss and blood transfusion,time to drainage tube removal,time to flatus and defecation,duration of postoperative hospital stay,expenses,changes of C-reactive protein on postoperative day 1,3,6,recovery of hepatic function and incidence of postoperative complications.All patients were followed up via phone call and out-patient examination till September 2013.All data were analyzed using the t test or chi-square test.The non-normal distribution paramenters were analyzed using the rank sum test.Results All patients were cured with no perioperative death.The time for postoperative drainage tube removal,time to flatus and defecation,duration of postoperative hospital stay and expenses were (2.3 ± 1.0)days,(2.5 ±0.5)days,(3.1 ±0.7)days,(7.0 ±0.8)days and (3.6 ±0.3) × 104 yuan in the FTS group,and (4.6 ± 0.7) days,(4.3 ± 0.7) days,(4.8 ± 0.4) days,(8.5 ± 0.9) days and (4.1 ± 0.3) ×104 yuan,with significant differences between the 2 groups (t =0.74,0.34,1.70,0.23,0.57,P ＜ 0.05).The levels of C-reactive proteins at postoperative day 1,3,6 were (56 ±7)mg/L,(122 ±7)mg/L and (35 ±7)mg/L in the FTS group,and (198 ± 24) mg/L,(137 ± 5) mg/L and (49 ± 8) mg/L,with significant differences between the 2 groups (F =64.91,P ＜0.05).The levels of prealbumin at postoperative day 1,3,6 were (196 ± 14) mg/L,(243 ± 17) mg/L,(260 ± 10) mg/L in the FTS group,and (198 ± 24) mg/L,(199 ± 16) mg/L and (245 ± 7) mg/L in the control group,with significant differences between the 2 groups (F =22.69,P ＜ 0.05).The levels of alanine transaminase at postoperative day 1,3,6 were (379 ±34)U/L,(166 ± 12)U/L,(49 ± 14)U/L in the FTS group,and (367 ±75)U/L,(210 ±28)U/L,(197 ±22)U/L in the control group,with significant differences between the 2 groups (F =4.51,P ＜ 0.05).One patient was complicated with peritoneal effusion and 1 with thoracic effusion in the FTS group; 4 patients was complicated with peritoneal effusion,3 with thoracic effusion,4 with pulmonary infection and 2 with incisional infection in the control group,with no significant difference in the complication between the 2 groups (x2 =0.78,1.11,4.44,2.11,P ＞ 0.05).All the patients were followed up for 2-24 months,no patients received reoperation or re-admitted to the hospital due to complications.Conclusion The application of FTS principle in the perioperative management of liver cancer patients after hepatectomy is safe and effective,it could alleviate the post-operative stress reaction and accelerate the recovery of liver function and patients' condition.

Objective To investigate the changes and clinical significance of the coagulation function after mitral valve replace‐ment (MVR) .Methods 163 cases of MVR admitted in our hospital from January 2012 to January 2014 were included in the obser‐vation group and contemporaneous 163 individuals of healthy physical examination were selected as the control group .The pro‐thrombin time (PT) ,activated partial thromboplastin time (APTT ) ,fibrinogen concentration (FIB) ,thrombin time (TT ) and pro‐thrombin time international normalized ratio (INR) in the two groups were detected and the detected results were performed the statistically comparative analysis .Results PT ,APTT and INR in the majority of the observation group were significantly higher than those in the control group ,the differences had statistical significance (P < 0 .05) .Conclusion The regular determination of blood coagulation function after MVR can effectively reflect the disorder status of anticoagulant and coagulation mechanism ,and can improve the efficiency of diagnosis and treatment and clinical predictive value .

Objective:To assess the characteristics change of sleep architecture in drug naive patients with schizophrenia,compared with healthy control.Methods:The key words including schizophrenia and sleep architecture (or sleep structure or sleep disturbance or polysomnogram and so on) were used to search literatures in MEDLINE,Embase,Springer,PsychINFO,google scholar,Wanfang data,published from 1980 to 2015.Fifteen studies that compared sleep architecture in drug naive patients with schizophrenia and healthy control were included.Literature quality evaluation was performed with the Newcastle-Ottawa Scale.The meta-analysis was performed by using Stata13.0 software.Results:Compared to healthy control,the total sleep time decreased (P ＜ 0.01),the sleep latency increased (P ＜ 0.01),the sleep efficiency decreased (P ＜ 0.01),and the rapid-eye-movemem (REM) sleep latency increased (P ＜ 0.01) significantly in drug naive patients with schizophrenia.The proportion of stage1 was increased,and the proportions of stage4 and slow wave sleep stage were decreased,the differences between case and control were statistically significant.Conclusion:In the control of drug effects,patients with schizophrenia may have poorer sleep quality of be poorer than healthy controls,such as the decreased total sleep time,specifically slow wave sleep,prolonged sleep latency and decreased sleep efficiency.

Objective To investigate the mechanism of an inhibitor of NADPH oxidases,diphenylene iodonium (DPI),in preventing radiation-induced lung injury.Methods Totally 48 adult SD male rats were randomly classified into 4 groups:control group (C),radiation group (R),radiation plus DPI group (R + D) and DPI group (D).The radiation induced pulmonary injury model was preformed by using 6 MV X-rays to deliver 8 Gy per day for 5 consecutive days with 40 Gy in total to the thorax of each animal.Rats in R + D group were subcutaneously administered with 0.02％ DPI (1 mg/kg) at 1 h prior to radiation while rats in D group received the same dose of DPI without radiation.DPI was given from 3 d before radiation to 30 d after the first radiation.Rats in C and D groups received the same dose of saline.Animals were sacrificed at 1 month and 6 months after radiation,respectively.The lungs were removed and processed for HE and Masson staining,hydroxyproline content measurement,and TGF-β1 immunohistochemical detection.Results At 1 month post-radiation,rats in R group showed typical alveolitis,the level of hydroxyproline was (0.69 ± 0.05) μg/mg,and the positive area of TGF-β1 expression was (39.97 ± 0.90) ％,while the level of hydroxyproline in R + D group was (0.55 ± 0.03) μg/mg and the positive area of TGF-β1 expression was(33.83 ± 1.55) ％,rats in R + D group showed less severe alveolitis compared with R group(t =5.32,5.93,P ＜0.05).At 6 months post-radiation,rats in R group showed typical lung fibrosis with hydroxyproline level of (1.04 ±-0.02) μg/mg and TGF-β1 expression of (37.80 ± 0.85) ％,whereas the hydroxyproline level in R + D group was (0.85 ± 0.02) μg/ mg,the TGF-β1 expression was(23.93 ± 1.16)％,rats in R + D group showed moderate lung fibrosis(t =15.77,16.68,P ＜ 0.05),rats in C and D group had no noticeable changes.Conclusions Diphenylene iodonium could prevent radiation-induced lung injury by reducing the level of hydroxyproline and the expression of TGF-β1.

A new molecular method for simultaneously rapid detection and differentiation of Mycobacterium tuberculosis, Mycobacterium bovis, Mycobacterium avium and Mycobacterium paratuberculosis was established by using denaturing high-performance liquid chromatography (DHPLC) combined with multiplex nucleic acid amplification. These 4 important pathogenic mycobacteria were identified by separation of 4 specific PCR-amplified target fragments by DHPLC analysis. A total of 51 Mycobacterium strains and 22 other bacterial species were tested to confirm the specificity of the multiplex PCR-DHPLC assay. The sensitivity of the assay was as low as 10~2-10~3 gene copies. This method rapidly identify the positive clinical samples from human and bovine with higher detection ratio than traditional culture method and was able to identify simultaneously four pathogenic Mycobacterium, which provided a new molecular tool for rapid detection of tuberculosis and paratuberculosis in human and animals.

Objective To explore the clinical effects of sequential flap of thigh perforator for closure of the anterolateral thigh free flap donor site.Methods From March,2014 to May,2015,8 consecutive patients underwent elective anterolateral thigh free flap reconstruction for limb soft tissue defect.To design a sequential flap of thigh perforator to achieve primary closure of the anterolateral thigh free flap donor site.The area of anterolateral thigh free flap ranged from 9.0 cm×6.0 cm to 20.0 cm×1 1.0 cm,respectively.The area of thigh perforator flap ranged from 7.0 cm×3.0 cm to 12.0 cm×7.0 cm.Results All flaps healed uneventfully.Distal skin flap necrosis appeared in 1 flap which was healed after local transposition flap.All the patients were followed up for 1 to 6 months,with mean time of 4 months.The color,texture and appearance of flaps were satisfactory.Conclusion Sequential flap of thigh perforator,with reliable blood supply and constant position,represents an ideal model to close the anterolateral thigh free flap donor site of small defect.

Objective To investigate the physics technique and quality assurance (QA) during radiotherapy in the institutions from the East Guangdong province,aiming to provide reference for the construction of radiotherapy discipline and rational allocation of resources in the primary hospitals from the eastern Guangdong province.Methods From March 15 to May 20,2016,the general conditions,radiotherapy equipment,available technique and quality assurance (QA) in the medical institutions from eastern Guangdong were investigated and analyzed by online combined with on-spot surgery.Results There were 8 institutions which provided radiotherapy with 966 ward beds,a daily capacity of 632 patients and 222 radiotherapy practitioners.Radiotherapy equipment included 12 linear accelerators,5 after-loading devices,1γ-knife,8 CT simulators and 9 radiotherapy planning systems.Five institutions performed IMRT/VMAT,IGRT and ART.Dose verification was performed before precision radiotherapy delivery in all institutions except for 1 center.QA procedures were missing for the linear accelerators,CT simulators and after-loading devices.Short-term advanced studies and hand-by-hand teaching were the main approaches for staff professional training.Conclusions The resource allocation for radiotherapy in the medical centers from the eastern Guangdong province is scarce.The technique and QC levels greatly differ among different institutions.Standard QA protocols are urgently to be established and implemented.Extensive attentions should be paid to the the professional training for technicians.

Objective To explore the clinical feasibility and safety of early intervention for severe stenosis of non-infarct related artery(non-IRA)in patients with acute ST-segment elevation myocardial infarction(STEMI) and multi-vessel disease(MVD)after successful primary percutaneous coronary intervention(PCI)for infarct-asso-ciated artery(IRA). Methods From May 1st,2011 to December 30th,2016,165 patients with STEMI and MVD were enrolled in our study. After the completion of primary PCI in IRA ,75 patients still in the hospital agreed to undergo a second staged PCI in severe stenosis of non-infarct arteries. We analyzed the in-hospital adverse events ,the length of hospital stay and clinical outcomes during the follow-up in the study population. Results There was no significant difference in the incidence of adverse events between the two groups during hos-pitalization. However,compared to patients treated with the IRA-only PCI,those treated with early intervention for severe stenosis of non-IRA was associated with greater benefits for clinical outcomes(including rehospitalization for heart failure,rehospitalization for ACS,recurrent angina pectoris,necessity for reintervention)during the follow-up except for the all-cause mortality. Conclusion Early intervention for severe stenosis of non-IRA is a feasible and safe procedure in patients with acute STEMI and MVD after successful primary PCI.

The global coronavirus disease 2019 epidemic is still in a pandemic state. Aging population with underlying diseases is prone to become severe, and have a higher mortality. The treatment capacity of the critical care department directly determines the treatment success rate of critical illness. At present, there is still a certain gap between domestic and foreign countries in intensive care unit (ICU), which is not only in the allocation of medical staff, but also in the beds and settings. The current medical model cannot fully meet the needs of development. The experience and lessons of many major public health emergencies suggested that " dual track of peace and war" approach in discipline construction of critical care is the best medical model. Following the concept of "combination of peace and war", strengthening the discipline construction of critical care department in municipal and district designated hospitals, allocating reasonable standard ICU, step-down ICU and combat readiness ICU, establishing rapid response team, and strengthening regular training and scientific management may be the key measures to deal with the epidemic.

Objective: To investigate the diagnosis and management of laryngeal cleft. Method: The clinical data of 13 cases of laryngeal cleft treated between 2007 and 2015 was analyzed retrospectively. Results: The children with laryngeal cleft were classified according to the classification of Benjamin-Inglis, as type Ⅰ(11 cases), typeⅡ(1 case) and type Ⅲ(1 case). All patients were confirmed by microlaryngobronchoscopy under general anaesthetic. Eleven typeⅠ and 1 type Ⅱ clefts were managed conservatively, with which all type Ⅰ patients were successfully managed, while the type Ⅱ patient was resolved by surgical endoscopy. The type Ⅲ patient was treated by open repair but the results was poor. Conclusions Patients who suffered with choking on feeding or recurrent aspiration pneumonia, especially coexisted with other congenital malformation, needed detailed evaluation for laryngeal cleft, although which was a rare congenital abnormality. Electronic laryngoscope could be the first step to screen the cleft, while microlaryngobronchoscopy is the gold standard for diagnosis of laryngeal cleft. The majority of children with lower type clefts can be managed conservatively. Surgical endoscopy has high success rate when strictly following the indication. Type Ⅲ and Ⅳ clefts have high mortality for usually combining with severe complications and abnormalities.
