AIM: To discuss the clinical efficacy of fresh amniotic membrane ( AM ) during the microscopic adjustable suture surgery in children's intercommunity strabismus, in order to guide clinical treatment.
METHODS: With the clinical randomized control study (RCT), 60 (112 eyes) cases of patients in childhood who received microscopic strabismus surgery in our hospital were divided them into two different groups from Jan. 2010 to Oct. 2015. According to the application of AM on the basis of ophthalmology outpatient number, 30 cases (58 eyes) in group A were treated with rectus muscle recession surgery combined adjustable suture combined with AM. The other 30 cases (54 eyes) in group B were treated with rectus muscle recession surgery combined adjustable suture only. All patients in two groups were followed-up over 6mo after the strabismus surgery.
RESULTS:Twenty-seven cases ( 48 eyes ) of all the strabismus patients must be adjusted after strabismus surgery, and the eye position adjustment rate was 42.9%. At 1mo after surgery, eye position of 18 cases (29 eyes) can be adjusted in all patients, and 44. 8% (16 cases, 26 eyes ) in group A with the average of adjustment lengths was 2. 56±0. 64mm, and 5. 6% ( 2 cases, 3 eyes ) in group B, with the average of adjustment lengths was 0. 52±0. 28mm, the differences of the adjustment rate and the average of adjustment amount were both high statistically significant (χ2 =22.477, P<0. 01; t=16. 502, P<0. 01 ) between the two groups. Except of 3 cases who couldn't cooperate with eye position adjustment, they all received eye position adjustment in different degrees in one month after strabismus surgery,and after eye position adjustment, 27 cases (53 eyes) in group A got normal eye position, and the correction rate of eye position was 91. 4%, and 16 cases (28 eyes) in group B got normal eye position after eye position adjustment, the correction rate was 51. 9%, the differences of the correction rate were statistically significant (χ2=21. 827, P<0. 01) between the two groups.
CONCLUSION: The application of fresh AM in the microscopic adjustable suture strabismus surgery is exactly effective in treatment of children's intercommunity strabismus. It can significantly extend the adjustment time and increase the adjustment amount, and it also can statistically improve the controllability and achievement ratio for children's strabismus surgery.

The purpose of this study is to identify the electrical activity of neuron, the existence of the transition from bursting pattern to spiking pattern and the ion mechanism of the bursting pattern. The intracellular electrical activity patterns of single neurons in the stomatogastric ganglion (STG) of crayfish were recorded when the extracellular calcium concentration ([Ca(2+)](o)) or calcium-dependent potassium channel blocker tetraethylammonium concentration ([TEA](o)) were changed, using intracellular recording method. These single neurons were also functionally isolated from the ganglion by application of atropine and picrotoxin which could block the inhibitory acetylcholine synapses and glutamatergic synapses respectively. When [Ca(2+)](o) was decreased by increasing EGTA, the membrane potential of the neuron was increased, and the electrical activity patterns were changed from the resting state with lower potential value (resting state of polarization) to the bursting pattern firstly, and then to the spiking pattern, at last to the resting state with higher potential value (resting state of depolarization). When [TEA](o) was increased, the membrane potential of the neuron was increased, and the electrical activity pattern was changed from the resting state with lower potential value (resting state of polarization) to the bursting pattern firstly, and then to the spiking pattern. The duration of the burst of the bursting pattern was increased. When [Ca(2+)](o) was increased or [TEA](o) was decreased, an inverse procedure of the electrical activity pattern was exhibited. On one hand, the results indicate that a single neuron can generate various electrical activity patterns corresponding to different physiological conditions, and the regularity of the transitions between different electrical activity patterns. On the other hand, the results identify that the initiation and termination of the burst in bursting pattern are determined by calcium-activated potassium conductance, which is adjusted by intracellular calcium concentration influenced by inward calcium current. It may be the ionic mechanism of generation of the bursting pattern in a single neuron.

Objective To predict the monthly incidence of hand-foot-mouth disease (HFMD) in China by using autoregressive integrated moving average (ARIMA) model and provide evidence for prevention and control of HFMD. Methods The monthly incidence data of HFMD in China from 2008 to 2016 were collected from the Public Health Science data Center. The incidence database was established by Excel 2007 and graphed. SAS 9.1 was used to construct the ARIMA model, based on the data of the monthly reported incidence of HFMD in China from January 2008 to December 2015, and then the data in 2016 were used to verify the predicted results. The monthly incidence in 2017 was predicted in the same way.The difference was statistically significant when P<0.05. Result The model predicting monthly incidence of HFMD in China is ARIMA ((12), 2, 0) sparse coefficient and residuals is white noise. The parameters were as follows: moted mean squared error=3.6490, mean absolute error=2.62, mean absolute percentage error=28.24%. Conclusion The sparse coefficient model could well simulate the trend of HFMD case in time series, which has good reference of early warning and prevention of HFMD.

OBJECTIVETo investigate the viral pathogens of acute lower respiratory tract infection (ALRTI) in hospitalized children from East Guangdong Province of China and the relationship of the pathogens with age and seasons.

METHODSThe nasopharyngeal aspirates samples obtained from 345 hospitalized children with ALRTI were investigated for respiratory syncytial virus (RSV), human bocavirus (HBoV), human metapneumovirus (hMPV), influenza virus types A and B, rhinovirus, parainfluenza virus types 1 and 3 and adenovirus by PCR.

RESULTSViral pathogens were detected in 178 patients (51.6%). RSV was the most frequent (19.3%). Novel viruses hMPV (3.2%) and HBoV (3.2%) were found. A highest detection rate (61.9%) of virus was found between January to March. The infants aged 1 to 6 months showed a higher detection rate (71.3%) of virus than the other age groups. The detection rate of viral pathogens was 72.6% in children with bronchiolitis, followed by asthmatic bronchitis (70.0%) and bronchial pneumonia (44.6%).

CONCLUSIONSRSV remained the leading viral pathogens in children with ALRTI in East Guangdong of China. Novel viruses HBoV and hMPV were also important pathogens. The detection rate of viral pathogens was associated with seasonal changes and age. Different respiratory infectious diseases had different viral detection rates, with highest detection rate in bronchiolitis cases.

OBJECTIVETo compare the efficacy and safety of remifentanil with fentanyl used for intraoperative anesthesia.

METHODSFifty-four patients undergoing modified radical mastectomy or total hysterectomy were randomly assigned to remifentanil group or fentanyl group with 27 cases in each group. Anesthesia was induced with propofol (2 mg/kg) and either remifentanil (2 micrograms/kg) or fentanyl (2.5 micrograms/kg), and was maintained with inhalation of nitrous oxide in oxygen (2:1) and a continuous infusion of either remifentanil (0.2 microgram.kg-1.min-1) or fentanyl (0.03 microgram.kg-1.min-1). Depth of anesthesia, hemodynamic changes, recovery profile of anesthesia, postoperative analgesia and adverse reactions were observed.

RESULTSThe number of patients exhibited light depth of anesthesia during tracheal intubation and maintenance in the remifentanil group was significantly fewer than that in the fentanyl group (P < 0.05). Hemodynamic changes during intubation, skin incision, maintenance of anesthesia and extubation in the remifentanil group were significantly smaller than those in the fentanyl group (P < 0.05, P < 0.01). The time to opening eyes on command and the time for extubation after surgery were comparable between the two groups. More patients in the remifentanil group required bolus injection of morphine for postoperative pain relief than those in the fentanyl group (P < 0.05). There was no significant difference between the two groups in the aspect of adverse reactions.

CONCLUSIONThe anesthetic and analgesic effects of remifentanil are more potent than those of fentanyl. Remifentanil can offer superior intraoperative hemodynamic stability compared with fentanyl without compromising recovery from anesthesia.

Objective To investigate the protective effect of modified Qianjin Weijing Decoction(MQJWJD)on TNF-α and NF-κB in rats with lung injury induced by particulate matter; To discuss relevant mechanism of action. Methods A tracheal drip 15 mg/kg fine particles of saline solution was used to establish modeling, every other day, three times. Thirty-two Wistar rats were randomly divided into normal group, model group and MQJWJD high-dose and low-dose groups, with eight rats in each group. Medication groups were given relevant medicine for gavage. The level of TNF-α in bronchoalveolar lavage fluid (BALF) was measured by ELISA. The expression of NF-κB protein in lung tissues was measured by immunohistochemistry. The histopathology of the lung injury was observed by light microscope. Results Compared with normal group, the level of TNF-α and the expression of NF-κB protein in the model group were higher than those in the normal group (P<0.01). Compared with model group, the level of TNF-α and the expression of NF-κB protein in MQJWJD low-dose and high-dose groups were lower than those in the model group (P<0.05, P<0.01). Pathological observation showed that, compared with normal group, model group showed intratracheal, alveolar and interstitial bacteria within a large number of fine particles calm, alveolar and pulmonary interstitial visible large amounts of phagocytic fine particles of macrophages and accompanied by more neutrophils and lymphocyte infiltration; Lung tissue pathological changes were significantly lighter in MQJWJD high-dose and low-dose groups than the model group. MQJWJD high-dose group showed mild inflammation, alveolar and pulmonary interstitial visible phagocytic fine particles of macrophages, a small amount of neutrophils and lymphocyte infiltration. Conclusion MQJWJD can reduce the pulmonary injury in rats induced by particulate matter and has protective effects on the rat model through decreasing the levels of TNF-α and the expressions of NF-κB protein in injured lung tissues.

This study aimed to construct the dual expression vectors of wide type or N187D mutant P2X7 receptor and intracellular domain of Notch1 (ICN1) linked by 2A peptide to coexpress them in leukemia cells so as to lay a foundation for further investigating the role of P2X7 in development of leukemia. Overlap PCR was used to construct the dual expression vectors encoding wide type or N187D mutant type P2X7 receptor and ICN1 linked by the self-cleaving 2A sequence. The results showed that stable expressing cell lines were obtained by retroviral infection followed by cell sorting after DNA sequence analysis. RT-PCR, Western blot, intracellular free calcium concentration analysis were used to verify the functionally successful construction of K562 cell line expressing P2X7 receptor alone or with ICN1. DNA sequence analysis revealed that all construction were right. The infection efficiency of packaged constructed virus ranged from 40% to 70% for K562 cells. Stable infected cell line was obtained by cell sorting. RT-PCR analysis revealed that P2X7 receptor and/or ICN1 could be detected at high level in their stable infected cell lines, respectively. Western blot analysis also showed that P2X7 receptor was highly expressed in cell line infected by virus with P2X7 receptor. Sustained increase in intracellular free calcium concentration ([Ca(2+)]i) could be observed in K562 cells overexpressing either type of P2X7 receptor upon stimulation with BzATP. It is concluded that the wide type or N187D mutant P2X7 receptor and ICN1 are simultaneously and functionally over-express in leukemia cells, which lay a foundation for further studying the role of P2X7 receptor in the development of leukemia.

Obstructive nephropathy ultimately leads to end-stage renal failure. Renovascular lesions are involved in various nephropathies, and most renal diseases have an ischemic component that underlies the resulting renal fibrosis. The aim of this study was to investigate whether morphological changes occur in the renal vasculature in hydronephrosis and the possible mechanisms involved. A model of complete unilateral ureteral obstruction (CUUO) was used. Experimental animals were divided into five groups: a normal control group (N) and groups of animals at 1st week (O1), 2nd week (O2), 4th week (O4) and 8th week (O8) after CUUO. Blood pressure was measured, renal arterial trees and glomeruli were assessed quantitatively, and renovascular three-dimensional reconstruction was performed on all groups. Glomerular ultrastructural changes were examined by transmission electron microscopy. The results showed that the systolic blood pressure was significantly increased in the obstructed groups (O1, O2, O4 and O8). Three-dimensional reconstruction showed sparse arterial trees in the O8 group, and a tortuous and sometimes ruptured glomerular basement membrane was found in the O4 and O8 groups. Furthermore, epithelial media thickness and media/lumen ratio were increased, lumen diameters were decreased, and the cross-sectional area of the media was unaltered in the segmental renal artery, interlobar artery and afferent arterioles, respectively. In conclusion, renal arterial trees and glomeruli were dramatically altered following CUUO and the changes may be partially ascribed to vascular remodeling. Elucidation of the molecular mechanisms of renovascular morphological alterations will enable the development of potential therapeutic approaches for hydronephrosis.

OBJECTIVETo evaluate the residual paralysis after a single intubating dose of rocuronium and its effect of residual paralysis after a single dose of rocuronium on the postoperative pulmonary function of patients undergoing laparoscopic gynecological surgeries.

METHODSSixty American Society of Anesthesiologists (ASA) I - II patients undergoing laparoscopic gynecological surgeries were randomly divided into rocuronium (R) group (n = 30) and rocuronium + neostigmine (R + N) group (n = 30).All patients received midazolam (0.02 mg/kg), fentanyl (1 microg/kg), propofol(1.5-2 mg/kg), and rocuronium (0.6 mg/kg) to facilitate tracheal intubation and no more relaxant thereafter. Anesthesia was maintained with isoflurane and nitrous oxide in oxygen (N(2)O:O(2) = 1:1). At the end of the procedure, neuromuscular blockade was not reversed in R group, while antagonism was accomplished with neostigmine (0.04 mg/kg) and atropine (0.02 mg/kg) in R + N group. Immediately after tracheal extubation and on arrival in the PACU, the train-of-four (TOF) ratio at the adductor pollicis of all patients were measured using acceleromyography. Forced vital capacity (FVC), forced expiratory volume in one second (FEV(1)), and peak expiratory flow rate (PEFR) of all patients were measured using spirometry before surgery, after administration of midazolam and fentanyl, immediately after tracheal extubation, on arrival in the PACU, and after the TOF ratio recovered to 1.0. The TOF ratio and pulmonary function between two groups were compared.

RESULTSImmediately after tracheal extubation and on arrival in the PACU, the mean TOF ratio in R group was significantly lower than that in R + N group (P < 0.05). The mean time to achieve TOF ratio of 0.9 and 1.0 in R group was significantly longer than in R + N group (P < 0.05). Immediately after tracheal extubation and on arrival in the PACU, FVC, FEV(1), and PEFR were significantly lower in R group than in R + N group (P < 0.05). FVC, FEV(1), and PEFR after administration of midazolam and fentanyl and after TOF ratio recovered to 1.0 were significantly lower than the baseline values in all patients (P < 0.01).

CONCLUSIONSAfter a single intubating dose of rocuronium, residual paralysis exists in the majority of patients undergoing laparoscopic gynecological surgeries. The pulmonary function is impaired after the surgery, even after recovery of TOF ratio to 1.0.
