Objective:To observe the effect of different doses of Fufang Huangbaiye Tuji asin the treatment onof the inflammatory response in healing process for of skin with deep Ⅱ degree burn. Methods in healing process. Methods:The 120 cses patients with deep Ⅱ degree burn of fire-toxin injuring fluid syndrome diagnosed in the affiliated hospital of Chengde Medical University between June 2019 and March 2020 were randomly divided into control group，low -dose treatment group and high -dose treatment group，with 40 cases in each group and once. They got a dressing change perevery day. Control group was locally administered with lodophor solution 35 mL per 1% on the body surface area. Low-dose treatment group was locally administered with compound cortex phellodendri fluid 17.5 mL per 1% on the body surface area，while high-dose treatment group was locally administered with compound cortex phellodendri fluid 35 mL per 1% on the body surface area. Observe theThe inflammatory reaction of wound surface in each group onwas observed at admission and after treatment. The pathological changes of each groupsgroup were observed， and determination of nuclear factor kappa-B（NF-κB） p65 expression inon the wound surface was determined by immunohistochemistry on the 4th day after the treatment. The levels of interleukin（IL）-2，IL-8 and tumor necrosis factor（TNF）-α in wound tissue were measured with ELISA and Bacterial culture and count were performed in each group on the 4^th，10^th and 21^st daydays after treatment. The levels of IL-2，IL-8 and TNF-α in wound tissue were measured with ELISA. Results:There was no significant difference in the degree of wound inflammation in each group at admission，and the degree of relief after treatment was positively correlated with the treatment time. At the simultaneous phase point，the inflammatory reaction was severest in control group，which was followed by low-dose treatment group and high-dose treatment group. Bacterial growth were observed on the 4^th day in control group，which was found in low-dose and high-dose treatment groups on the 10^th day，the detection rates of Staphylococcus aureus and Pseudomonas aeruginosa were the highest. Compared with control group，the mean integrated optical density of NF-κB p65 in wound tissue decreased markedly in low-dose and high-dose treatment groups on the 4th day after treatment（P<0.05），the bacterial count decreased significantly in low-dose and high-dose treatment groups on the 10^th and 21^st days after treatment（P<0.05），and the levels of IL-2，IL-8 and TNF-α in wound tissue decreased markedly in low-dose and high-dose treatment groups on the 4^th，10^th and 21^st days after treatment（P<0.05），with statistically significant differences between low-dose and high-dose treatment groups（P<0.05）. Histopathological examination showed that inflammatory granulocytes and edema were improved in low-dose and high-dose treatment groups compared with control group，with a more significant performance in high-dose treatment group. Conclusion:The external application of compound cortex phellodendri fluid can reduce thebacterial growth of bacteria in on the wound surface，which may reduce the inflammatory reaction by inhibiting the production and release of inflammatory mediators，with a certain dose-effcteffect relationship，and is worth clinical promotion.

Objective:To study the intervention effect and underlying mechanism of Fufang Huangbaiye Tuji （FFHBY） on skin with deep Ⅱ degree burn wound. Method:Patients with deep Ⅱ degree burn of fire-toxin injuring fluid syndrome diagnosed in the Affiliated Hospital of Chengde Medical University from June 2019 to June 2020 were randomly divided into a control group （iodophor solution， 35 mL per 1% body surface area）， a low-dose treatment group （FFHBY， 17.5 mL per 1% body surface area）， and a high-dose treatment group （FFHBY， 35 mL per 1% body surface area）， 40 cases in each group. The patients in each group were treated correspondingly with dressing chance once per day. The pathological changes of the wound were observed on the 14th day after treatment. Wound symptoms and signs in each group before treatment and on the 7th， 14th， and 21st days after treatment were quantified， and the clinical efficacy on the 21st day after treatment was evaluated. Wound healing rates in each group were calculated on the 7th， 14th， and 21st days after treatment. The levels of vascular endothelial growth factor （VEGF）， fibroblast growth factor （FGF）-2， FGF-7， epidermal growth factor （EGF）， interleukin （IL）-10， tumor necrosis factor （TNF）-α， and Caspase-3 in wound tissues were measured with enzyme-linked immunosorbent assay （ELISA）. Nuclear factor kappa-B （NF-κB） p65 expression in wound surface was detected by immunohistochemistry. The apoptosis rate in wound tissues was determined by the TdT-mediated dUTP-biotin nick end labeding assay （TUNEL） method. Result:There was no significant difference in scores of symptoms and signs among groups before treatment. Compared with the control group， the treatment groups showed no significant difference in wound healing rates on the 7th day after treatment and increased healing rates on the 14th and 21st day after treatment（P<0.05）. The clinical efficacy in the treatment groups was superior to that in the control group on the 21st day after treatment. Additionally， the treatment groups also showed decreased scores of local symptoms and signs， increased levels of VEGF， FGF-2， FGF-7， EGF， and IL-10， and dwindled apoptosis rate and levels of Caspase-3， TNF-α， and NF-κB p65 expression in wound tissues on the 7th，14th and 21st day after treatment （P<0.05）. The high-dose treatment group was superior to the low-dose treatment group in the above indicators （P<0.05）. Histopathological examination showed that inflammatory cell infiltration was relieved in the treatment groups as compared with that in the control group， and the high-dose treatment group exhibited superior efficacy. Conclusion:FFHBY had an obvious therapeutic effect on deep Ⅱ degree burn. It could promote wound healing by up-regulating the level of growth factors， improving inflammatory response， and inhibiting cell apoptosis in a dose-dependent manner.

Psoriasis is characterized by abnormal proliferation of keratinocytes, as well as infiltration of immune cells into the dermis and epidermis, causing itchy, scaly and erythematous plaques of skin. The understanding of this chronic inflammatory skin disease remains unclear and all available treatments have their limitations currently. Here, we showed that IMMH002, a novel orally active S1P modulator, desensitized peripheral pathogenic lymphocytes to egress signal from secondary lymphoid organs and thymus. Using different psoriasis animal models, we demonstrated that IMMH002 could significantly relieve skin damage as revealed by PASI score and pathological injure evaluation. Mechanistically, IMMH002 regulated CD3 T lymphocytes re-distribution by inducing lymphocytes' homing, thus decreased T lymphocytes allocation in the peripheral blood and skin but increased in the thymus. Our results suggest that the novel S1P agonist, IMMH002, exert extraordinary capacity to rapidly modulate T lymphocytes distribution, representing a promising drug candidate for psoriasis treatment.

OBJECTIVE: To explore long-term following-up clinical effects of lateral closed high tibial osteotomy for the treatment of knee osteoarthritis. METHODS: Twenty patients with medial unicompartmental knee osteoarthritis were treated with lateral closed high tibial osteotomy and screw fixation from June 2005 to December 2015. Among them, including 17 females and 3 males, aged from 43 to 76 years old with an average of (57.80±8.05) years old. VAS score and KSS score were applied to evaluate recovery degree of pain and function before operation and after operation at 1, 5 and 10 years, and postoperative complications were observed. RESULTS: Sixteen patients were followed-up, the time ranged from 9 to 11(10.0±0.8) years, 4 patients were loss to follow-up. Preoperative VAS score was 7.88±1.15 and decreased to 3.19±0.91, 3.44±0.96, 3.69±1.20 at 1, 5 and 10 years after operation, and there were statistical differences in VAS score between before and after operation at different time points (<0.05). Clinical score of KSS increased from 61.94±5.74 before opertaion to 75.50±4.62, 80.13±3.97, 77.38±6.40 at 1, 5 and 10 years after operation, and there were statistical differences in clinical score of KSS between before and after operation at different time points(<0.05); functional score of KSS increased from 62.81±13.03 before operation to 77.50±8.56, 81.88±6.55, 76.88±10.78, and there were statistical differences in functional score of KSS between before and after operation at different time points(<0.05). All incisions healed well without complications such as fibula nerve injury and fracture nonunion. CONCLUSIONS Lateral closed high tibial osteotomy and screw fixation for knee osteoarthritis could receive good clinical results, stop and delay progress of knee osteoarthritis, and long-term following-up could achieve the same effect as total knee arthroplasty.

Objective To analyze the rationality of the combined application prescriptions of traditional Chinese and Western medicine; To discuss the problems in the evaluation of the combined application of traditional Chinese and Western Medicine. Methods A total of 12 issue monthly outpatient combination application prescriptions of traditional Chinese and Western medicine were randomly selected in Gansu Provincial Hospital of Traditional Chinese Medicine (Here in after referred to as "this hospital"). According to the relevant laws and regulations, evaluation rules of the combined application traditional Chinese and Western medicine was developed, reviewed and statistically summarized. Results Totally 1900 prescriptions were sampled in the study and accounted for 8.67% in all prescriptions (including prescription of traditional Chinese herbal medicine) and accounted for 20.87% of all prescription of pure Western medicine and pure traditional Chinese patent medicine in the same period, which meet the requirements of sampling rate. Prescriptions of department of orthopedics accounted for the majority. The average number of drugs and the average amount of each prescription of department of orthopedics were lower than the overall average. The sample consisted of 1852 patients, 796 males and 1056 females. Middle-aged patients (36-60 years old) of combined medication were up to 49.46% of the total number of patients. 3990 terms of diagnosis were involved, including 1908 terms of traditional Chinese medicine diagnosis and 2082 terms of Western medicine diagnosis. Orthopedics disease diagnosis accounted for more than 50%. The main problems of the combined application of traditional Chinese and Western medicine were the non syndrome differeentiationg use of medicine, inappropriate usage and dosage, and the lack of attention to medicine interactions. Conclusion The combined application prescriptions of traditional Chinese and Western medicine of this hospital account for a small proportion. Prescription structure adapts with the size of the department, patient age and disease diagnosis. In the future, the prescription evaluation and intervention of syndrome differeentiationg application and dosage and medicine interaction should be strengthened.

BACKGROUNDChronic kidney disease (CKD) is a growing public health problem with well-established risk factors. Other contributing factors, however, remain to be identified. Systemic inflammation in asthma plays a significant role in the development of other diseases. We therefore initiated a study to assess whether the growing prevalence of asthma is associated with an increase in the risk of CKD.

METHODSWe conducted a retrospective cohort study using data from 3015 patients with asthma aged 14 years and older who were registered and followed up in Asthma Control Study at the Department of Respiratory Medicine of three medical centers from 2005 to 2011. History, asthma control test (ACT), and asthma stage were used to assess the traits of asthma. CKD was defined as proteinuria and/or reduced estimated glomerular filtration rate (eGFR) (<60 ml×min(-1)×1.73 m(-2)) in two consecutive follow-up surveys. We used logistic regression models, adjusting for age, sex, and other confounding factor to determine associations between the traits of asthma and CKD. Kaplan-Meier curves were used to analyze patient outcomes.

RESULTSA total of 2354 subjects with complete data were recruited for this study with mean age (45.4±10.4) years. After 6 years of follow-up, 9.6% (n = 227) of the analytic cohort developed proteinuria and 3.1% (n = 72) progressed to eGFR <60 ml×min(-1)×1.73 m(-2). The patients with >20 years asthma history, not well-controlled or persistent asthma patients had higher incidence of proteinuria and reduced eGFR compared with patients with ≤20 years asthma history, at least well-controlled or remission asthma, respectively. The multivariable adjusted OR for proteinuria and reduced eGFR in participants with persistent asthma was 1.49; (95% confidence interval (CI) 1.17-1.91) and 2.07 (95% CI 1.34-4.42). Compared to patients with no asthma traits, there was a significant risk (OR, 3.39; 95% CI 1.36-8.73) for those who met all three traits, including asthma history >20 years, not well-controlled and persistent stage, after adjusting for potential confounding factors.

CONCLUSIONSIn this retrospective cohort study, we found that persistent asthma was associated with an increased risk of CKD, which was independent of obesity, diabetes, hypertension, and other well-established risk factors. Future studies should be directed to elucidate the mechanisms underlying the association between asthma and CKD.
