Objective To investigate the effects of angiotensin Ⅱ (Ang Ⅱ) on the expression of TLR4 and its role in lipopolysaccharide (LPS)-induced NF-κB activation and CD40 expression in rat peritoneal mesothelial cells (RPMCs). Methods RPMCs were harvested from Spragne-Dawley rat peritoneal cavity and maintained under defined in vitro condition. The cells were treated with Ang Ⅱ at different concentrations (10-9, 10-8, 10-7, 10-6 mol/L) and exposed to Ang Ⅱ (10-7 mol/L) for different times (1, 2, 4, 8, 12, 24, 48 h for mRNA and 6, 12, 24, 36, 48 h for protein, respectively). Meanwhile, the influence of AT1 receptor antagonist (AT1R, losartan, 10-5 mol/L) and AT2 receptor blocker (AT2R, PD123177, 10-5 mol/L) on the TLR4 induced by Ang Ⅱ was observed. After synchronization for 24 hours, the cells were randomly assigned to four groups: the control group, the Ang Ⅱ (10-7 tool/L) group, the LPS (1 mg/L) group, the Ang Ⅱ (10-7 mol/L) plus LPS (1 mg/L) group, which were used to investigate the effects of Ang Ⅱ on the NF-κB activation and CD40 expression induced by LPS. The mRNA expression of TLR4 and CD40 was measured by RT-PCR and the protein abundance of TLR4, NF-κB p65, phospho-p65, IKBα and phospho-IκBα were analyzed by Western blot. Immunofluorescence was performed to determine the subcellular localization of p65 subunit of NF-κB. Results (1) Treatment of RPMCs with Ang Ⅱ resulted in a concentration-dependent increase in the expression of TLR4. Ang Ⅱ at 10-9, 10-8, 10-7 and 10-6 mol/L increased TLR4 mRNA expression by 70.5%, 89.5%, 102.9%, and 121.9%, respectively and protein expression by 12.1%, 27.7%, 51.2%, and 41.6%, respectively (P<0.01). Treatment of RPMCs with 10-7 mol/L Ang Ⅱ resulted in a time-dependent increase in the expression of TLR4, with the peak of mRNA expression at 8 and 12 h (P<0.01) and the protein expression at 12 and 24 h (P<0.01). (2) Losartan antagonized Ang Ⅱ-stimulated expression of TLR4 by 33.5% (P<0.05), PD123177 had no such effect (P0.05). (3) Treatment of RPMCs with LPS (1 mg/L) for 60 rain significantly increased the ratio of phospho-IκBα to IκBα by 362.6% (P< 0.01) , phospho-p65 to p65 by 67.4% (P<0.05), and LPS (1 mg/L) for 4 h significantly increased the expression of CD40 mRNA by 299.9% (P<0.01) compared to the control group. In comparison to the LPS (1 mg/L) group, preincubation of RPMCs with AngⅡ (10-7 mol/L) for 24 h then treated with LPS (1 mg/L) for 60 rain significantly increased the ratio of phospho-IκBα to IκBα by 49.1% (P<0.01), phospho-p65 to p65 by 29.3%(P<0.05), and LPS (1 mg/L) for 4 h significantly increased the expression of CD40 mRNA by 56.8%(P<0.01). (4) The p65 subunit of NF-κB was dominantly distributed in the cytoplasm in the control and Ang Ⅱ group. Following exposure to LPS for 60 min, p65 subunit labeling was upregulated and translocated into the nuclei. A significantly increased nuclear staining of p65 in ceils treated with Ang Ⅱ plus LPS were observed. Conclusions Ang Ⅱ induces the expression of TLR4 in dose- and time-dependent manner in RPMCs, resulting in enhanced NF-κB signaling and induction of CD40 expression, Locally produced Ang Ⅱ in the peritoneum may play an amplified role in LPS-induced peritoneal inflammation.

Water soluble extract (WSE) is an important index for the quality evaluation of Astragali Radix (AR). In this study, the WSE of the wild AR from Shanxi province (SX) and the cultivated AR from Gansu Province (GS) were compared. The WSEs of two types of AR were determined according to the appendix of Chinese pharmacopoeia. Then the WSEs were subjected to NMR analysis, and the obtained data were analyzed using HCA, PCA, OPLS-DA, microarray analysis, and Spearman rank analysis. In addition, the Pearson correlation of differential metabolites were also calculated. The results showed that the WSE content of GS-AR (37.80%) was higher than that of SX-AR (32.13%). The main constituent of WSE was sucrose, and other 18 compounds, including amino acids, organic acids, were also detected. Multivariate analysis revealed that SX-AR contained more choline, succinic acid, citric acid, glutamate, taurine and aspartate, while GS samples contained more sucrose, arginine and fumaric acid. In addition, the Pearson correlations between different metabolites of the two types of AR also showed apparent differences. The results suggested that the WSE of two types of AR differs not only in the content, but also in the chemical compositions. Thus, the cultivation way is important to the quality of AR. This study supplied a new method for the comparison of extract of herbal drugs.

Objective:To study the clinical value of artificial dermis combined with autologous thin skin graft in the repair of burn scar contracture in joints.Methods:A total of 52 patients with burn scar contractures were enrolled in the No.5 Hospital of Baoding from July 2015 to April 2018. According to different methods of repair, 26 cases were used in each group. The observation group was treated with artificial dermis combined with autologous thin skin graft. The control group was treated with medium-thickness skin grafting. The survival rate of autologous skin was compared between the two groups. The tissue of artificial dermal polyester fiber was taken and HE staining was performed to observe the pathological changes. The Vancouver skin scar assessment score (VSS), functional activity, infection rate, wound healing time, and VSS score after healing of the donor site were compared between the two groups.Results:The survival rate of autologous skin in the observation group (92.31%) was not significantly different from that in the control group (84.62%) ( P>0.05). Compared with preoperative, the VSS scores at 3, 6 months and 1 year after operation in both groups were decreased ( P<0.05). The VSS scores of the observation group were lower than those of the control group at 3, 6 months and 1 year ( P<0.05). The excellent rate of functional activity in the observation group (100.00%) was higher than that of the control group (76.92%) ( P<0.05); There was no significant difference in the infection rate (3.85% vs 7.69%) and healing time of skin grafting area between the two groups ( P>0.05). The healing time of donor site was shorter than that of the control group ( P<0.05). The VSS score of the donor site was lower than that of the control group ( P<0.05). Conclusions:Artificial dermis combined with autologous thin skin graft can be used in patients with burn scar contracture in joints, which can improve the scarring of skin grafting area and donor site, shorten the healing time of donor site and improve the function of burn scar contracture joint.

OBJECTIVE: To analyze the latency of posture evoked response of normal lower limb muscle in different stimulations and explore its influencing factors. METHODS: The normal lower limb was induced to produce postural evoked response by the dynamic posturography through two kinds of perturbations, the supporting surface rotation stimulation (Toes-up and Toes-down) and the horizontal perturbation stimulation (Forward and Backward). The latencies of tibialis anterior muscle and gastrocnemius muscle were recorded by surface electromyography acquisition system. The differences of the left and right limb, gender and height on the latency of postural evoked response were analyzed. RESULTS: (1) Under the Toes-up and Backward perturbation, the latency of tibialis anterior muscle was longer than gastrocnemius muscle; under the Toes-down and Forward perturbation, the latency of gastrocnemius muscle was longer than tibialis anterior muscle. (2) The latencies of left limb and right limb had no significant difference. (3) The latency in male was longer than that in female. (4) The latency gradually increased with the increase of height. CONCLUSION In the postural evoked response, different perturbations, gender and height have significant impacts on the latency of posture evoked response of lower limb muscle. However, the effect of height and gender should be not considered referring to the same individual.

OBJECTIVETo investigate the feasibility and effectiveness of modified Stoppa approach in treatment of bilateral pubic fractures of pelvic.

METHODSThe therapeutic effects of 16 patients with bilateral pubic fractures treated through the modified Stoppa approach from January 2010 to January 2014 were summarized and analyzed, involved 11 males and 5 females with an average age of 40.5 years old ranging from 17 to 59 years. According to Tile classification, there were 8 patients with type A, 6 with type B and 2 with type C. For 16 pelvic fractures, the modified Stoppa approach was used exclusively 11 cases, in combination with the iliac fossa approach in 4 cases, and in combination with the posterior approach in 1 case. The operation incision length, operation time , intra-operative blood loss and postoperative complications were observed. The fracture reduction and post-operative function were assessed by Matta criteria and Majeed system respectively.

RESULTSThe incision length of the modified Stoppa approach ranged from 8 to 10 cm (averaged in 9 cm). The operation time ranged from 75 to 135 minutes (averaged in 95 minutes). The intra-operative blood loss ranged from 400 to 900 ml (averaged in 600 ml). Sixteen patients were followed up from 7 to 18 months (averaged in 12.5 months). The fractures were all healed, the fracture healing time was 2.7 to 5 months (means 3.1 months). There were no infections, ectopic ossification, screw loosening, plate breakage and lateral ventral syndrome. According to Matta criteria for pubic fracture reduction, the result was excellent in 9 cases, good in 6, fair in 1. The Majeed function scores at 6 months after operation was 85.32±8.50; the result was excellent in 8 cases, good in 6 cases, fair in 2 cases.

CONCLUSIONThe modified Stoppa approach has characteristics of convenience and directness of incisions, clear operation field, easy reduction, few complications and fast recovery , it is an ideal choice in surgical treatment of bilateral pubic fractures.

OBJECTIVETo measure the threshold of feeling temperature, comfortable temperature and tolerant temperature to ginger-partition moxibustion and suspended moxibustion at different acupoints of healthy persons, and to instruct the clinical practice of moxibustion better.

METHODSForty-three healthy students were divided into a ginger-partition moxibustion group (22 cases) and a suspended moxibustion group (21 cases) randomly. Shenshu (BL 23), Zhongwan (CV 12), Zusanli (ST 36) and Waiguan (TE 5) were used in both groups. The feeling temperature, comfortable temperature and tolerant temperature in each group were measured by thermometer. SPSS 18.0 was used to analyze the data.

RESULTSThe feeling temperature, comfortable temperature and tolerant temperature rose in proper order and the difference was significant (all P < 0.05). The tolerant temperature of suspended moxibustion group ((40.69 +/- 1.85) degrees C) was lower than that of ginger-partition moxibustion group ((42.44 +/- 3.90) degrees C) (P < 0.05). The feeling temperature of ginger-partition moxibustion at Shengshu (BL 23) was 4-5 degrees C lower than that at other acupoints.

CONCLUSIONThe heat sensations of different acupoints to ginger partition moxibustion and suspended moxibustion are different at different stages. The threshold of heat sensation of ginger-partition moxibustion is higher than that of suspended moxibustion. There is a best temperature zone for moxibustion which is a little higher than normal temperature between comfortable temperature and tolerant temperature. To improve effect, doctors should try to prolong the effective time of this zone in clinic. As the limiting temperature of patients, tolerant temperature can provide reference for the use of moxibustion safely in clinic.

Objective To investigate the status of the disease of the fluorosis and arsenism caused by coal-burning in Ankang city of Shaanxi. Methods Nine survey spots were chosen to carry out the epidemiological investigation of adult skeletal fluorosis and arsenism in the coal-polluted areas of Ankang, respectively using Determination of Fluorine in Coal (GB/T 4633-1997) to determine the coal fluorine and using hydride generation atomic fluorescence spectrophotometry(HCAFS) to determine coal arsenic. The diagnose of the adult skeletal fluorosis followed the Diagnosis of Clinical Classification for Endemic Skeletal Fluorosis Standard(GB 16396-1996), that of arsenism using Standard of Diagnosis for Endemic Arsensim (WS/T 211-2001). Results Totally 569 adults were investigated over the age of 16, among which 121 cases were skeletal fluorosis, with a total detection rate of 21.27%. Four cases of II degree and higher skeletal fluorosis patients were identified, accounting for 0.70% of the number of subjects. One hundred and thirty-two cases of arsenic poisonin were detected, in a rate of 23.20%. Ninety-five patients were identified with moderate or severe arsenic poisoning, accounting for 16.69% of subjects. A positive correlation was found between the detection rates of the skeletal fluorosis and the arsenism(r = 0.816, P < 0.01), as well as between the detection rate of skeletal fluorosis and fluoride content of coal(r = 0.775, P < 0.05). The detection rate of arsenism and arsenic content of coal also had close relationship (r = 0.761, P < 0.05). The detection rate of skeletal fluorosis in the group aged 40 - ,50 - , and 60 - [27.20%(34/125) ,29.27%(36/123), 28.13%(36/128)] was increased, compared the group of less than 40 years age[7.77%( 15/193), X~2 = 21.969,25.648,23.856,P<0.01].For the detection rate of arsenism,male[33.67%(99/294)]was obviously higher than female[12.00%(33/275),)(X~2=37.162,P<0.01].Conclusions A high detection rate of fhorosis is correlated with arsenic poisoning,but the probability of the two diseases simultaneously occurred in a person is not high.In this polluted area.when fluoride accumulates to a certain level as in aduh,the detection rates no longer varies obviously;however,that of arsenism increases along with the age.
