Objective To discuss the change of sympathetic skin response (SSR) in patients with cerebral thrombosis with no more than 60 years old. Method SSR was measured in four positions of the center of hand palm and foot palm of 40 normal controls ( control group ) and 56 cerebral thrombosis patients (cerebral thrombosis group) no more than 60 years old. Results SSR wave shape was all educed in control group,but 21 limbs (21/224,9.4%) were not educed in cerebral thrombosis group, SSR abnormality was 80 limbs (35.7% ). SSR's latency in cerebral thrombosis group was obviously prolonged as compared with control group,and the amplitudes of SSR of upper limps and lower limbs had significance between two groups (P< 0.05 or < 0.01). There were serious abnormity within 3 days to 2 months after cerebral thrombosis. Conclusion SSR is a sensitive diagnosis method for the autonomic neuropathy of cerebral thrombosis patients of no more than 60 years old.

Objective To explore the expressions of Toll-like receptors (TLRs) 2 and 4 in mouse skin during early immune responses against Sporothrix.Methods A total of 60 BALB/c mice were randomly and equally divided into an experimental group and a control group to be intracutaneously injected with Sporothrix conidium suspensions at a concentration of 1 × 106 cfu/ml and sodium chloride physiological solution respectively.Five mice were sacrificed before the injection,and at 6,12,24,48,and 96 hours after the injection in each group,blood samples were obtained from the mice before sacrifice,and skin tissue specimens were resected from the area around the injection sites after sacrifice.Realtime fluorescence-based quantitative PCR was performed to quantify the mRNA expressions of TLR2 and TLR4,and immunohistochemical staining to observe the protein expressions of TLR2 and TLR4 in mouse skin specimens.Enzymelinked immunosorbent assay (ELISA) was conducted to determine the levels of interleukin 12 (IL-12) and tumor necrosis factor α (TNFα) in serum samples from the mice.Results After injection of Sporothrix conidium suspensions,the mRNA expression level of TLR2 gradually increased and peaked at 24 hours,which was 18.8 times that in the control group at 6 hours and 34 times at 24 hours.In addition,the mRNA expression level of TLR4 in the experiment group reached a peak,and was 56.7 times that in the control group at 6 hours after injection,then gradually decreased and reached the nadir at 96 hours.As immunohistochemical staining revealed,TLR2 and TLR4 were apparently expressed in both keratinocytes and macrophages in skin specimens from the experimental group,but not obviously in those from the control group.No significant differences were observed between the experimental group and control group in serum levels of IL-12 or TNF-α at any of the sampling time points.Conclusion TLR2 and TLR4 may play a favoring role in immunological defense by participating in the recognition of Sporothrix by keratinocytes and macrophages in mouse skin.

Objective:To study on the effect of ultrasound-guided thoracic paravertebral nerve (TPVB) block on quality of recovery from general anesthesia in tuberculosis patients with fiberboard exfoliation in post anesthesia recovery unit (PACU).Methods:From May 2018 to December 2019, 40 tuberculosis patients in Changsha Central Hospital with pulmonary fibreboard exfoliation and focal abscess lesions cleaning were randomly divided into two groups, with 20 patients in each group. The patients in group A received endobronchial general anesthesia and in group B received ultrasound-guided TPVB combined with endobronchial general anesthesia. Patients in the two groups were maintained under anesthesia by propofol, and the bispectral index (BIS) was maintained within the range of 40-50. The dosage of propofol and sufentanil was adjusted according to changes in BIS and hemodynamics. The mean arterial pressure (MAP), heart rate (HR) in two groups of patients were recorded at before anesthesia induction (T 0), before cutting leather (T 1), cut skin after (T 2), the end of operation (T 3), extubation time (T 4), and T 5 (time of leaving PACU). The visual analogue scale (VAS) of all patients in resting and cough state was recorded at 5, 30 min after extubation and the time of leaving PACU. The dosage of propofol and sufentanil in the operation and the additional dosage of sufentanil in PACU were recorded in both two groups. And the respiratory recovery time, consciousness recovery time, extubation time and sedation agitation scale(SAS) were observed. The adverse reactions such as nausea, vomiting, drowsiness and hypotension were observed in PACU. Results:Compared with group A, MAP and HR of patients at T 2, T 3, T 4, T 5 in group B were more stable during anesthesia, and VAS of patients in group B were lower than that in group A at each time point after extubation ( P<0.05). The dosage of sufentanil and propofol in group B were (35.92±8.12)μg and (749.56±95.30)mg respectively, which were significantly lower than those in group A [(45.74±4.42)μg and (862.83±105.34)mg, P<0.05]; the dosage of sufentanil in postoperative anesthesia recovery room of group B was (5.26±2.10)μg, significantly less than that of group A (10.35±5.86)μg ( P<0.05). The respiratory recovery time, consciousness recovery time and extubation time in group B were (12.92±5.12) min, (20.56±5.10) min and (26.87 ± 6.16) min, which were shorter than those in group A [(15.74±4.72)min, (25.83±5.34)min and (35.35±5.80)min, P<0.05]. The incidence of postoperative nausea, vomiting, lethargy and hypotension in group B were 10%, 10%, 35% and 20%, which were significantly lower than those in group A (30%, 20%, 75% and 45%, P<0.05). Conclusions:Ultrasound-guided paravertebral nerve block may significantly reduce the dosage of opioid analgesics for general anesthesia in tuberculosis patients with fiberboard exfoliation, accelerate the speed of anesthesia recovery, reduce the agitation during recovery, and improve the quality of anesthesia recovery.

OBJECTIVE To investigate the effect of subcutaneousimmunotherapy(SCIT) on levels of the serum human beta defensin-2 in children with allergic rhinitis. METHODS 30 cases of children with allergic rhinitis who were treated by SIT were selected as the treatment group, 20 cases of healthy children as the control group. Serum HBD-2 concentration of the control group was tested. Serum HBD-2 concentration of the treatment group was tested at three different time points: before SCIT, half a year after SCIT and one year after SCIT. And total nasal symptom scores(TNSS) and medication scores were recorded at each time point. RESULTS The serum HBD-2 concentration of the control group, that of the treatment group before SIT, half a year after SIT and one year after SIT were 4.62[4.08; 4.87], 3.74[3.37; 4.61], 4.62[4.13; 5.54], 4.79[4.45;6.19]ng/ml. The HBD-2 concentration gradually increased after SCIT. The TNSS of the treatment group before SCIT, half a year after SCIT and one year after SCIT were 7.43±2.15, 4.17±2.16, 4.20±1.92, The medication scores of the treatment group before SCIT, half a year after SCIT and one year after SCIT were 1.25[0.75; 1.38], 0.25[0; 0.75, 0.25[0; 0.75].There was no correlation (all P>0.05) between the serum HBD-2 concentration and TNSS or medication scores of the treatment group. CONCLUSION The serum levels of HBD-2 in patients with allergic rhinitis were lower than those in normal persons. The specific immunotherapy raised the serum HBD-2 levels of allergic rhinitis patients.

Objective To evaluate the safety,efficacy and comfort of dexmedetomidine sedation combined with ultrasound-guided ilioinguinal and ilioinguinal nerve block in open inguinal hernia surgery for elderly patients with underlying diseases.Methods 40 elderly patients for open inguinal hernia surgery with underlying diseases were selected and randomly divided into group A and group B.Group A recived simple nerve block,while group B recived dextropyrimidine sedation combined with nerve block.The heart rate (HR),mean arterial pressure (MAP),SpO2,Ramsay sedation score and visual analogue score (VAS) at T0 (entering operating room),T1 (anesthesia puncture),T2 (15 min after anesthesia),T3 (surgical incision),T4 (hernia sac free),T5 (operation ending) in both two groups were recorded,and the intraoperative anesthesia effect were evaluated.The satisfaction rate,incidence of bradycardia,bradycardia and respiratory depression were compared between the two groups;and observed the sufentanil using,lidocaine using and the occurrence of adverse reactions.Results There was no significant difference of SpO2 at each time point between the two groups (P ＞ 0.05);HR,MAP and Ramsay sedation scores at T0 between the two groups had no significant difference (P ＞ 0.05);compared with group A,HR,MAP and Ramsay scores at T1-T5 in group B decreased and Ramsay scores increased,while VAS at T1,T3,T4 and T5 in group B were lower (P ＜ 0.05);in group B,local anesthesia with lidocaine at puncture point,intraoperative sufentanil and body movement were significantly reduced,and the overall satisfaction rate of patients was high (P ＜ 0.05).There were no obvious adverse reactions in both groups.Conclusions Dexmedetomidine sedation combined with ilioinguinal/iliohypogastric nerve block is safe and effective in elderly patients with open hernia surgery combined with basic diseases,and it can improve the comfort of patients during anesthesia puncture and operation more than simple nerve block.

Objective:To evaluate the clinical effect of Qingjin-Huatan Decoction combined with conventional western medicine in the treatment of acute aggravation of bronchiectasis. Methods:A total of 80 patients in Beijing Sixth Hospital from January 2014 to December 2018 were included. Patients were divided into two groups according to random number table method, 40 cases in each group. The control group was treated with conventional western medicine. The research group was treated with Qingjin-Huatan Decoction based on the control group. Both of the two groups were treated continuously for 7 days. Before and after the treatment, their symptoms and signs were scored, forced expiratory volume in one second (FEV1), forced vital capacity (FVC) and peak expiratory flow (PEF) were detected by pulmonary function tester, serum neutrophil elastase (NE) and cathepsin G were detected by ELISA, tumor necrosis factor-α (TNF-α), interleukin-4 (IL-4) and interleukin-6 (IL-6) in sputum were detected by ELISA, and clinical efficacy was evaluated. Results:The total clinical effective rate of the research group and the control group was 90.0% (36/40) and 77.5% (31/40) respectively. The difference between the two groups was statistically significant ( χ2=4.501, P=0.034). After the treatment, the scores of cough, expectoration, phlegm quality, phlegm quantity, fever, shortness of breath, thirst, chest distress and wet rales in the research group were significantly lower than those of the control group ( t values were 15.240, 16.910, 21.761, 18.949, 16.740, 9.285, 11.732, 9.050, 11.193, all Ps<0.001), FEV1, FVC and PEF were all significantly higher than those of the control group ( t values were 5.085, 4.468 and 4.219, respectively, all Ps<0.001), the levels of TNF-α, IL-4 and IL-6 in sputum were all significantly lower than those of control group ( t values were 8.341, 8.884 and 11.352, respectively, all Ps<0.01), and the levels of serum NE (26.20 ± 3.18 μg/L vs. 51.15 ± 5.24 μg/L, t=25.744) and cathepsin G (5.62 ± 1.01 μg/L vs. 8.05 ± 1.33 μg/L, t=9.203) were significantly lower than those of control group ( P<0.001).
