Abstract
Objective: To analyze the longitudinal characteristics of CD4+T lymphocytes (CD4) among the adult HIV/AIDS on antiretroviral therapy (ART) and the related factors. Methods: A retrospective cohort of adult HIV/AIDS starting ART in Dehong Dai and Jingpo Autonomous Prefecture (Dehong) in 2007-2016 was followed up to December 31, 2018. Group-based trajectory models were utilized to identify CD4 subgroups based on immune recovery (whether and when CD4 reached the average level of >500 cells/μl). The demographics and information at ART baseline were described, and the related factors were analyzed with polytomous logistic regression. The SAS 9.4 software was used for statistical analysis. Results: A total of 7 605 adults with HIV/AIDS were included, of which the median (P25,P75) age at ART were 36 (30,43) years old, 61.0% were male, 42.5% were Han nationality, and 60.8% with the education of primary school or below. The follow-up duration M (P25, P75) was 6.1 (4.1,8.1) years. HIV/AIDS in Dehong showed four CD4 trajectory subgroups from low to high: below the average level, primary recovery to a normal level, full recovery to a moderate level, and normal steady level, accounting for 34.4%, 39.8%, 20.6%, and 5.2%, respectively. When compared with corresponding control groups, age <35 years at ART, female, education of middle school or above, sexual transmission, no opportunistic infection, CD4 ≥200 cells/μl, baseline regimen with tenofovir (TDF) and time from HIV diagnosis to ART <1 year were the related factors facilitating the higher CD4 subgroups. Conclusions: The various CD4 immune recoveries of HIV/AIDS were changing patterns after ART. Starting ART with a high CD4 level was beneficial to CD4 recovery to normal level during the follow-up period. Early initiation of ART and exceptional attention to CD4 immune recovery should be encouraged after the ART.

Abstract
SummaryObstructive sleep apnea (OSA) is closely related to the development of various diseases. Hypoxic perfusion caused by OSA can mediate the occurrence of inflammatory reactions or aggravate metabolic disorders to affect intestinal microecological balance. Intestinal bacteria can participate in the development of inflammatory reaction or metabolic disorder by itself or its components, and the oxidative stress reaction of the body develops in a vicious circle. The mechanism has not yet been fully elucidated, so we reviewed the research progress on OSA and intestinal microecological balance.

Abstract
Objective:The aim of this study is to investigate the effects of rhodiola rosea on oxidative stress, anxiety and depression in patients with OSA. Method:Ninety patients with moderate and severe OSA patients with negative emotions diagnosed by PSG, self-rating depression scale (SDS) and self-rating anxiety scale (SAS) were selected from the respiratory department of our hospital from February 2015 to February 2018. According to the random number table method, the patients were randomly divided into non-invasive ventilator group, rhodiola rosea+non-invasive ventilator group and rhodiola rosea group, with 30 cases in each group. Patients in the non-invasive ventilator group were treated with continuous positive airway pressure (CPAP) for 3 months, and those in the rhodiola rosea+non-invasive ventilator group were treated with oral rhodiola capsules for 3 months on the basis of CPAP, and those in the rhodiola rosea treatment group were treated with pure oral rhodiola capsules for 3 months. The changes of SDS and SAS before and after the three groups were compared, and the changes of serum SOD and MDA were detected by immunoenzyme-linked adsorption for comparative analysis. Result:There were no significant differences in SDS and SAS scores between the three groups (P>0.05). SDS and SAS scores of patients in the rhodiola rosea+non-invasive ventilator group decreased after treatment (P<0.05) compared with those in the non-invasive ventilator group. SDS and SAS scores of patients in the rhodiola treatment group increased after treatment (P<0.05). Compared with those in the rhodiola treatment group, SDS and SAS scores of patients in the rhodiola+non-invasive breathing group decreased after treatment (P<0.05). Three group patients were no significant difference in serum SOD and malondialdehyde (MDA) before treatment (P>0.05). Compared with before treatment, serum SOD level were all increased and MDA level were all decreased in the three groups after treatment (P<0.05). Compared with noninvasive breathing unit after treatment, rhodiola+noninvasive breathing unit after treatment in patients with elevated levels of serum SOD, MDA level decreased (P<0.05), and for the treatment group after treatment in patients with serum SOD levels drop, the MDA levels (P<0.05), and the after rhodiola rosea treatment group compared, rhodiola+noninvasive breathing unit after treatment in patients with elevated levels of serum SOD, MDA level decreased (P<0.05). Conclusion:Rhodiola may improve the negative emotions such as anxiety and depression by inhibiting oxygen free radicals and lipid peroxidation in patients with OSA.

Abstract
Objective: To analyze the deaths with antiretroviral treatment among adult HIV/AIDS patients in Liangshan Yi Autonomous Prefecture from 2005 to 2015, in order to understand the epidemiological characteristics and to further reduce the mortality rate in Liangshan Prefecture. Methods: The relevant information was collected through the Management Database of Antiretroviral Treatment from the National AIDS Comprehensive Prevention Information System. Results: From 2005 to 2015, a total of 14 219 adult HIV/AIDS patients received antiretroviral treatment and 1 425 death cases were reported during the treatment. The cause of death was mainly AIDS-related diseases (58.9%), and the cumulative mortality rate was 10.02%. Gender, age, the way of infection, duration of antiretroviral therapy, clinical stage when received antiretroviral therapy, and CD(4)(+) T lymphocyte levels were factors for the mortality rate (P<0.001). The mortality increased with older age, higher initiation clinical stage and lower level of CD(4)(+) T lymphocyte. Among the death cases, 82.6% were male, 1 182 (82.9%) were married or cohabited, most aged between 30-39 years old (48.6%). At the initial point of receiving antiretroviral therapy, 49.7% of the cases with CD(4)(+)T lymphocytes levels< 200/μl, 61.2% of the deaths cases were>1 000 copies/ml during the last viral load test, and 16.2% of deaths were ≥500/μl in the last CD(4)(+)T lymphocyte test; 44.5% of deaths were received antiretroviral treatment within one year. Conclusion: Early and timely antiretroviral therapy should be carried out. It is necessary to strengthen the propaganda of antiretroviral therapy and to improve the management quality of follow-up information of antiretroviral therapy case files, and to improve the medication compliance of patients.

Abstract
Objective: To evaluate the effect of peripheral hyperinsulinemia on assessment of pharmacokinetics (PK) and pharmacodynamics (PD) of insulin preparations in euglycemic clamp. Method: A total of 40 healthy male volunteers aged 18-45 years old in West China Hospital between 2015 and 2017 were divided into euglycemic-hyperinsulinaemic clamp (A) group and euglycemic clamp (B) group. Humulin R (0.2 U/kg) was given subcutaneously at steady state of clamp after infusion of short-acting insulin in A group while in B group Humulin R was given subcutaneously without establishment of artificial hyperinsulinemia. The blood glucose was maintained within target range during the whole clamp. Result: Maximum insulin concentration [(667±141) pmol/L vs (267±68) pmol/L, P<0.01] and area under curve (AUC) of insulin concentration [(152±32) nmol·L(-1)·min vs (57±7) nmol·L(-1)·min, P<0.01] in A group were higher while maximum glucose infusion rate (GIR) [(3.70±0.70) mg·kg(-1)·min(-1) vs (7.66±2.11) mg·kg(-1)·min(-1), P<0.01] and AUC of GIR [(931±272) mg/kg vs (1 920±452) mg/kg, P<0.01] were lower compared to B group. The serum C-peptide levels were lower in both groups after administration of insulin compared with baseline. Conclusion: It is not necessary applying euglycemic-hyperinsulinaemic clamp to evaluate the PK/PD of insulin preparations, which may overestimate the PKparameters and underestimate the PD parameters of insulin preparations.

Abstract
Zigzag silicene nanoribbons (ZSiNRs) in the ferromagnetic edge ordering have a metallic behavior, which limits their applications in spintronics. Here a robustly half-metallic property is achieved by the boron substitution doping at the edge of ZSiNRs. When the impurity atom is replaced by the aluminum atom, the doped ZSiNRs possess a spin semiconducting property. Its band gap is suppressed with the increase of ribbon's width, and a pure thermal spin current is achieved by modulating ribbon's width. Moreover, a negative differential thermoelectric resistance in the thermal charge current appears as the temperature gradient increases, which originates from the fact that the spin-up and spin-down thermal charge currents have diverse increasing rates at different temperature gradient regions. Our results put forward a promising route to design multi-functional spintronic devices which may be applied in future low-power-consumption technologies.

Abstract
As a generic property, all substances transfer heat through microscopic collisions of constituent particles 1 . A solid conducts heat through both transverse and longitudinal acoustic phonons, but a liquid employs only longitudinal vibrations2,3. As a result, a solid is usually thermally more conductive than a liquid. In canonical viewpoints, such a difference also serves as the dynamic signature distinguishing a solid from a liquid. Here, we report liquid-like thermal conduction observed in the crystalline AgCrSe2. The transverse acoustic phonons are completely suppressed by the ultrafast dynamic disorder while the longitudinal acoustic phonons are strongly scattered but survive, and are thus responsible for the intrinsically ultralow thermal conductivity. This scenario is applicable to a wide variety of layered compounds with heavy intercalants in the van der Waals gaps, manifesting a broad implication on suppressing thermal conduction. These microscopic insights might reshape the fundamental understanding on thermal transport properties of matter and open up a general opportunity to optimize performances of thermoelectrics.

Abstract
Recently, a holey two-dimensional (2D) C2N crystal with a wide band gap has been successfully synthesized. However, its non-magnetic property largely limits real applications in spintronics. Here we find that edge magnetism can be introduced by tailoring the holey 2D C2N crystal into nanoribbons with zigzag edges. When edge N atoms are bare or passivated by H atoms, the device can be used to design high-performance thermospin devices and thermal rectifiers. This is ascribed to the emergence of a spin semiconducting property with a wide band gap. Moreover, if the edge N atoms are passivated by O atoms, the device shows a half-metallic property; meanwhile an obvious spin Seebeck effect can also be observed when a temperature difference is applied across the device.

Abstract
OBJECTIVE To investigate adherence and the influence factors among patients who are on antiretrovirus therapy (ART) of 3 provinces in China. METHODS This study selected 18-year-old and older AIDS patients as the survey objects who initiated anti-retrovirus therapy between April and September of 2014 and kept on the treatment for one year in Yunnan,Sichuan,and Hu'nan province. Information of demography, treatment and social support was collected by questionnaires. Adopt SSRS questionnaire to calculate the information of objective support, subjective support and utilization of social support. χ(2) test and logistic regression were performed to examine relationships between factors and adherence. RESULTS A total of 386 patients with medication were investigated. Among them, there were 365 (94.6%) cases who were compliant to the ART, and 357 (92.5%) cases can take their pills on time, and 29 (7.5%) cases take their medication in excess of the prescribed time more than two hours. Social support score was 27.2 ± 7.3, including objective support score (5.6 ± 2.7), subjective support score (16.1 ± 4.8), and utilization of social support (5.5 ± 1.9). Multivariate logistic regression analysis revealed that adherence was significantly associated with the correct cognition of medication (OR (95%CI): 3.24 (1.17-9.00)), the self-awareness of the drug regimen was not complexity (OR (95%CI): 9.34 (3.27-26.68)), taking medication 1 time a day (OR (95%CI): 4.00 (1.35-11.84)), and the batter utilization of social support (OR (95%CI): 1.49 (1.06-2.01)). Married/cohabiting or farmers tend to be nonadherenced, while the OR (95%CI) was 0.24 (0.08-0.67) and 0.23 (0.08-0.69), respectively. CONCLUSION The patients among these provinces were compliant to the ART, and most of them can take their pills on time. The social support score of these patients was lower than normal person. Participants who have correct cognition of medication, thinking their drug regimen was not complexity; Taking medication 1 time a day or have high level of utilization of social support showed a significantly higher level of self-reported adherence.

Abstract
Fano effect is an important quantum phenomenon in mesoscopic systems, which arises from an interference between the localized state and the extended state. Here we observe an obvious Fano effect near the Fermi level in an all-carbon molecular device consisting of an acene molecule sandwiched between two zigzag graphene nanoribbon (ZGNR) electrodes. By increasing the length of the molecule, an extended state gradually evolves into a localized state. With the aid of the nearby extended state, a Fano effect is achieved. Using a gate voltage, we can easily tune the Fano effect induced by the single-transmission channel. When the spin degree of freedom is involved, the all-carbon device can show a half-metallic property with positive or negative 100% spin polarization at the Fermi level under the gate voltage; meanwhile the spin thermoelectric effect can also be enhanced.

Abstract
Under normal conditions, progesterone inhi-bits the estrogen-induced proliferation of endometrial epithelium. Our previous studies have shown that cyclin G1 was progesterone-dependent in mouse endometrial epithelium at peri-implantation, and exogenous cyclin G1 suppressed the proliferation of endometrial cancer cells. The objectives of this study are to determine whether cyclin G1, as a negative regulator of the cell cycle, is involved in the antiproliferative action of progesterone on endometrial epithelial cells, and to explore the possible molecular mechanism of cyclin G1 inhibition. The siRNA-mediated elimination of cyclin G1 attenuated the antiproliferative action of progesterone on endometrial epithelial cells. Immunoprecipitation showed that progesterone-induced cyclin G1 could interact with PP2A to mediate its phosphatase activity. The block of PP2A activity also attenuated the antiproliferative action of progesterone on endometrial epithelial cells and increased the phosphorylated Rb. In conclusion, progesterone-induced cyclin G1 mediates the inhibitory effect of progesterone on endometrial epithelial cell proliferation possibly through the recruitment of PP2A to dephosphorylate Rb.

Abstract
Numerous studies have shown that human endogenous retrovirus W family (HERV-W) envelope gene (env) is related to various diseases but the underlying mechanism has remained poorly understood. Our previous study showed that there was abnormal expression of HERV-W env in sera of patients with schizophrenia. In this paper, we reported that overexpression of the HERV-W env elevated the levels of small conductance Ca(2+)-activated K(+) channel protein 3 (SK3) in human neuroblastoma cells. Using a luciferase reporter system and RNA interference method, we found that functional cAMP response element site was required for the expression of SK3 triggered by HERV-W env. In addition, it was also found that the SK3 channel was activated by HERV-W env. Further study indicated that cAMP response element-binding protein (CREB) was required for the activation of the SK3 channel. Thus, a novel signaling mechanism of how HERV-W env influences neuronal activity and contributes to mental illnesses such as schizophrenia was proposed.

Abstract
Microarray technology is becoming a powerful tool for clinical diagnosis, as it has potential to discover gene expression patterns that are characteristic for a particular disease. To date, this possibility has received much attention in the context of cancer research, especially in tumor classification. However, most published articles have concentrated on the development of binary classification methods while neglected ubiquitous multiclass problems. Unfortunately, only a few multiclass classification approaches have had poor predictive accuracy. In an effort to improve classification accuracy, we developed a novel multiclass microarray data classification method. First, we applied a "one versus rest-support vector machine" to classify the samples. Then the classification confidence of each testing sample was evaluated according to its distribution in feature space and some with poor confidence were extracted. Next, a novel strategy, which we named as "class priority estimation method based on centroid distance", was used to make decisions about categories for those poor confidence samples. This approach was tested on seven benchmark multiclass microarray datasets, with encouraging results, demonstrating effectiveness and feasibility.

Abstract
β-amyloid 1-42 (Aβ1-42)-induced learning and memory impairment in rats is believed to be associated with inflammation. Cytokine production is a key pathologic event in the progression of inflammatory processes. In this rat study, soybean isoflavones (SIF) was used to investigate it's protective effects on inflammation caused by β-amyloid 1-42 (Aβ1-42), which is associated with learning and memory impairment in Alzheimer disease. We characterized the learning and memory ability. cytokine profiles of circulating interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α) in the serum and the expression of Toll like receptor4 (TLR4) and nuclear factor-κB p65 (NF-κB p65) mRNA and protein in the brain tissue following intracerebroventricular administration of Aβ1-42 by miniosmotic pump for 14 days. The results showed that functional deficits of learning and memory in SIF treatment groups were significantly improved compared to the control group without SIF treatment in water maze test. The serum IL-1β and TNF-α level were significantly increased, and the expressions of TLR4 and NF-κB p65 mRNA and protein in the brain were up-regulated, indicating inflammation response was initiated following administration of Aβ1-42. After intragastric pre-treatment with SIF, inflammatory cytokines was significantly reduced and also SIF reversed the Aβ1-42 induced up-regulation of TLR4 and NF-κB p65 mRNA and protein expression in the brain and expression of NF-κB p65 in nuclei. These results suggested that SIF reduced the cytokine cascade and inflammatory response induced by Aβ1-42 which could result in the improvement of spatial learning and memory ability impairment in the rats.

Abstract
We isolated a novel strain of Alphaproteobacteria from a patient, who had medical history of chronic rhinitis for more than twenty years and recently experienced local skin abscess and ulcer. He eventually died of multiple organ failure due to multi-antibiotics resistance. We identified the microorganism by 16SrRNA sequencing and found that it belonged to the genus Rhodoplanes. It was named as Rhodoplanes sp. strain ZLJ-0. It is resumed that Rhodoplanes sp. strain ZLJ-0 might be an emerging human pathogen involving in unknown febrile conditions and could cause local infection of any tissues or organs. Differential diagnosis of febrile patients should be conducted in clinical practice and research on emerging pathogens of Alphaproteobacteria should be performed to determine the epidemiology, clinical symptoms and pathogenic features of these pathogens.

Abstract
This work experimentally studied the effects of ozonation treatment on waste sludge. During the treatment process, various parameters characterizing sludge were investigated. A substantial reduction in the volume of sludge and the release of intracellular and extracellular materials were observed. With the increase of ozone dose, the settleability and water content of sludge improved obviously, but the filterability of sludge deteriorated drastically. In addition, the evolution of particle size was evaluated, which proved the breakup of sludge flocs and cells. There existed a threshold of ozone dose which was 0.04 gO(3)/gMLSS in this work. Above the threshold, the soluble chemical oxygen demand (SCOD), protein, carbohydrate, total nitrogen and total phosphorus in supernatant increased remarkably and the electron transport system (ETS) sludge activity decreased. Organic nitrogen and organic phosphorus occupied the main part of total nitrogen and total phosphorus in the supernatant.

Abstract
Peripheral nerve regeneration is a complex series of events, involving bi-directional interactions between regenerating axons and Schwann cells. These authors have demonstrated in their laboratory that nerves will regenerate through a 3-cm autogenous venous nerve conduit (AVNC) in an animal model and, with Dr. David Chiu, a similar distance in the human. They have shown that the upper limit of nerve regeneration in an empty AVNC was 3 cm, with no evidence of nerve growth at the 6-cm mark (no-growth model). Most recently, they have demonstrated rapid growth at 1 month in a 3-cm AVNC filled with Schwann cells, compared to poor-to-no-regrowth at 1 month in controls. While, in theory, Schwann-cell-derived growth factor should be sufficient to supplant the requirement for Schwann cells, in practice, therapies with growth factors have failed in clinical trials, with some resulting in severe morbidity and mortality for the subjects. The present study showed excellent nerve regeneration through a 6-cm AVNC with the addition of autologous Schwann cells, breaking the barrier in the previous no-growth model. In the first stage, autologous Schwann cells were harvested from the contralateral peroneal nerve of the rabbit and expanded in culture. The Schwann cells were purified to >99 percent homogeneity using differential adhesion and antibody-compliment-mediated cytolysis. In the second stage, 6 cm of gluteal vein were harvested and used as a conduit that was filled with either Matrigel or a slurry of Matrigel and 10(6)/ml autologous Schwann cells (n=6 control and 6 experimental animals). The non-donor side peroneal was exposed and transected, leaving a gap of 6 cm. The filled gluteal vein graft (AVNC) was then anastomosed to the proximal and distal peroneal nerve stumps, and the rabbits were allowed to recover. Four months postoperatively, the animals were subjected to transcardiac perfusion with EM grade fixative. The grafts were analyzed at the light and electronmicroscopic levels, and showed excellent growth of nerve at 6 cm, the distal end of the AVNC.

Abstract
When cross-linked by heating or by gamma-irradiation and entrapped in cellulose, whey proteins can generate insoluble biofilms with good mechanical properties and high resistance to attack by proteolytic enzymes. Interchain cross-linking of proteins generated an increase in the puncture strength, and a decrease in water vapor permeability. Gelatin was added in film formulation as a stabilizer to improve the puncture strength and film appearance. The structure of the biofilms was also analyzed. SDS-PAGE revealed that heating and gamma-irradiation produce an increase of the molecular weight of the cross-linked protein. Size exclusion chromatography showed a molecular mass of 40 kDa for un-cross-linked whey proteins, whereas for the soluble fractions of the cross-linked proteins, molecular distributions were between 600 and 3800 kDa for the heated proteins and between 1000 and 2000 kDa for gamma-irradiated proteins. No major alteration of the structural conformation of the proteins was observed by FTIR for biofilms obtained after heat treatment, whereas gamma-irradiation induced some modifications in the protein structure. X-ray diffraction analysis suggests that cross-linking by gamma-irradiation seems to modify the conformation of proteins, which became more ordered and more stable.

Abstract
The mechanical properties of cross-linked edible films based on calcium caseinate and two type of whey proteins (commercial and isolate) were investigated. Cross-linking of the proteins was carried out using thermal and radiative treatments. Size-exclusion chromatography performed on the cross-linked proteins showed that gamma-irradiation increased the molecular weight of calcium caseinate, while it changed little for the whey proteins. However, heating of the whey protein solution induced cross-linking. For both cross-linked proteins, the molecular weight distribution was >/=2 x 10(3) kDa. Combined thermal and radiative treatments were applied to protein formulations with various ratios of calcium caseinate and whey proteins. Whey protein isolate could replace up to 50% of calcium caseinate without decreasing the puncture strength of the films. Films based on commercial whey protein and calcium caseinate were weaker than those containing whey protein isolate. Electron microscopy showed that the mechanical characteristics of these films are closely related to their microstructures.

Abstract
This paper dealt with the data of Tripterygium wilfordii polyoglucoside (1 mg/kg.d) combined with Radix Salvaie multiorrhizae (6-15 g/d) for treating purpuric nephritis (group-A), compared with the control group of using Tripterygium wilfordii polyoglucoside treatment only (group-B). The average time of edema-disappearing and blood pressure-resuming to normal range were 8.72 +/- 3.07 and 7.44 +/- 5.17 days in group-A, which were much better than those in group-B (P < 0.05). The average time of blood urine-disappearing in group-A and group-B were 36.37 +/- 11.50 and 47.73 +/- 14.03 days respectively. The average time on C3 in the urine resumed to normal in groups A and B were 40.33 +/- 4.51 and 50.00 +/- 5.30 days respectively (P < 0.01). The time of microcirculation of nail fold returned to normal after treatment in group-A and group-B were 39.00 +/- 11.03 and 66.00 +/- 9.01 days respectively (P < 0.001). These results indicated that the effect of group-A was much better than that of group-B.

Abstract
Twenty females, aged 31 to 49 years, scheduled for abdominal total hysterectomy were randomly divided into two groups in this study. An epidural catheter was placed at T11-12 before general anesthesia. All patients receive the combination of epidural anesthesia and general anesthesia for the operation and relief of pain postoperatively. The modified endotracheal tube we used is shown in Fig. 1. For patients in group I (Lidocaine group), 2 mL 4% lidocaine solution was injected through the catheter to desensitize the tracheal mucosa around the cuff after the surgeon had removed the uterus. In group II (Control group), no special management was made. All patients were not extubated until they were considered to be awake. Systolic blood pressure at three and one minute before extubation and pulse rate recorded at one minute before extubation showed in patients of group I were statistically smoother than those recorded in group II (p less than 0.01). All patients had gag reflex just after awake extubation.

Abstract
Balanced salt solution (BSS) and balanced salt solution plus (BSS+), alone and in combination with heparin or superoxide dismutase (SOD), were used as irrigation solutions for rat groin flaps after prolonged ischemia. SOD always improved flap survival when it was present in solution, although when combined with BSS and BSS+, it was less effective than when combined with Ringer's lactate. The physiological pH solutions BSS and BSS+ had no advantages over Ringer's lactate in any of the tested combinations.

Abstract
The conventional endotracheal tube was modified with an epidural catheter adhered on the concave aspect of it. The opening of the catheter is at the proximal margin of the cuff. Local anesthetic can be injected into the trachea, then desensitize the tracheal mucosa nearby the cuff. Thirty-four female gynecological patients underwent abdominal total hysterectomy were studied and divided into three groups. In group 1, anesthesia was maintained without special management. In groups 2 and 3, 2 mL gentian violet stained 4% lidocaine solution was administered intratracheally by two different methods 60-120 minutes before the conclusion of the surgery. The peak cuff pressures generated by the awakening patients were 53.8 +/- 2.2 cm H2O (mean +/- SE) in group 1, 47.3 +/- 2.5 cmH2O (Group 2) and 36.4 +/- 1.6 cmH2O Group 3) respectively. Bucking before awakening was also evaluated clinically and showed 100%, 73% and 0% in each group. Intratracheal administration of lidocaine in dose of 2 mL 4% showed significant effect for the suppression of bucking during the recovery of general anesthesia in group 2 and 3 compared with the group 1. Lidocaine administered through the catheter of modified endotracheal tube also resulted in less increase in the peak cuff pressure and even no clinically observed bucking than direct administered through the endotracheal tube. Gag reflex was preserved in all patients and none had suffered from aspiration postoperatively.

Abstract
Vascular repairs using a combination of Vicryl rings to evert vessel edges and the Tisseel two-component fibrin adhesive system failed to achieve patent microanastomosis without using stay sutures. The bonding force of Tisseel alone was not sufficient to hold the cut ends of rat femoral arteries and veins together. All 10 arterial and 8 venous end-to-end anastomoses separated under normal intraluminal pressure immediately after the removal of microclamps. This method was found to be an unacceptable alternative to the conventional suturing method.

Abstract
Since the first successful replantation of a severed right hand was reported in 1963, surgeons in China have performed more than 3735 replantations of limbs and digits with increasing improvement in the survival rate. Of special interest is that local hospitals have reported numerous successful cases revealing a popularization of this kind of operation in China. The replantation survival rate is related to the type of injury and duration of anoxia. The types of injury include avulsion or crush amputation, severed distal segments of fingers, immersion conditions, amputated limbs or digits in children, and segmental resection of diseased tissues. The results are analyzed by a special system of functional evaluation.
