Oral mucositis (OM) caused by cancer therapy is the most common adverse reaction in the radiotherapy of head and neck tumors. In severe cases, it can lead to the interruption of treatment, which affects the control of the disease and the quality of life. Shuanghua Baihe Tablet (SBT) is a traditional Chinese medicine (TCM) formula, which is administerd to treat OM in China. It has been clinically effective for more than 30 years, but the underlying mechanism is not completely understood. With the development of multiple omics, it is possible to explore the mechanism of Chinese herbal compound prescriptions. Based on transcriptomics and metabolomics, we explored the underlying mechanism of SBT in the treatment of OM. An OM model of rats was established by 5-FU induction, and SBT was orally administered at dosages of 0.75 and 3 g·kg

Objective To explore the clinical features,diagnoses,differential diagnoses and treatments of superior cerebellar artery aneurysms.Methods The clinical data of 16 patients with superior cerebellar artery aneurysms,admitted to our hospital from January 2013 to March 2018,were retrospectively collected.Their clinical manifestations,imaging features,surgical effects and related problems in the process of diagnoses and treatments were analyzed.Results Among the 16 patients,11 were caused by aneurysm rupture;8 had subarachnoid hemorrhage alone,and three had subarachnoid hemorrhage accompanied by ventricular hemorrhage;CT and CTA confirmed that 8 were superior cerebellar artery aneurysms,two were posterior cerebral artery aneurysms,and one was with unclear diagnosis.In the other 5 patients,three had eyelid ptosis and two had abducent nerve palsy;CT,CTA or MR imaging showed that two were considered as ventral brainstem occupying lesions,and three did not have clear diagnosis.Finally,all patients were diagnosed as having superior cerebellar artery aneurysms by three-dimensional DSA.Five patients were treated with interventional embolization first,and one was treated with surgical clipping because of vertebral artery stenosis and difficulty of catheter access;two patients were transferred to our department for surgical clipping due to aneurysm rupture after embolization treatment in other hospitals;and 9 patients were treated by surgical clipping directly.After treatments,one patient was in bed for a long time due to cerebellar infarction and systemic complications,and the other 15 patients recovered well;two of them underwent ventricular peritoneal shunt due to hydrocephalus.Conclusions Superior cerebellar artery aneurysm has onset of subarachnoid hemorrhage mostly,and oculomotor and abductor nerve paralysis,and space occupying manifestation around the brainstem sometimes.For patients with suspicious posterior circulation aneurysms whose diagnosis or location are unclear,three-dimensional DSA examination should be performed early to confirm the diagnosis.Treatment should be taken as soon as possible once the superior cerebellar artery aneurysm is defined.Interventional embolization may be the first choice,but it is necessary to master the methods of surgical clipping in order to treat the disease timely.

Chondral injuries are short of self-healing ability and need to surgical repair after articular cartilage injury. Conventional treatment includes debridement and drainage under arthroscope, micro-fracture, osteochondral autograft transplantation (OATS), mosaiplasty and osteochondral allografts (OCA), autologous chondrocyte implantation (ACI). Debridement and drainage could remove pain factor, and has advantages of simple operation, wide clinical application and early clinical effect. Micro-fracture and osteochondral autograft transplantation is suitable for small area of cartilage repair, while the further effect showed that fibrous cartilage permeated by drill could decrease postoperative clinical effect. Osteochondral autograft transplantation has better advantages for reconstruction complete of wear-bearing joint. Autologous chondrocyte implantation and allogeneic cartilage transplantation are suitable for large area of cartilage defect, postoperative survival of allogeneic cartilage transplantation is effected by local rejection reaction and decrease further clinical effect. Cartilage tissue engineering technology could improve repair quality of autologous chondrocyte implantation, and make repair tissue close to transparent cartilage, but has limit to combined subchondral bone plate, reactive bone edema, bone loss and bad axis of lower limb. New technology is applied to cartilage injury, and has advantages of less trauma, simple operation, rapid recover, good clinical effect and less cost;and could be main method for treat cartilage injury with surgical repair technology. How to improve repair quality with compression resistance and abrasive resistance are expected to be solved.

Objective To investigate the clinical data, risk factors for bleeding following endoscopic treatment of colorectal polyps (diameter ≥ 1.0 cm) and feature analysis for carcinogenesis of adenomatous polyps. Method It was analyzed retrospectively that the clinical data, endoscopic characteristics, risk factors for bleeding and features for carcinogenesis of adenomatous polyps in 741 patients with a total of 884 colorectal polyps (diameter ≥ 1.0 cm) of our hospital from January 1, 2014 to January 1, 2016, which were resected under endoscope. Result Univariate analysis of colorectal polyps resected under endoscope on intraoperative and delayed bleeding, we found that gender (P = 0.017), location (P = 0.011), size (P = 0.004), lobulated or not (P = 0.010), resection methods under endoscope (P = 0.029) were statistically significant deviation between the two groups; taking the polyp as observation unit,multivariate Logistic regression analysis of their clinical data and endoscopic characteristics, we found gender (P = 0.012, OR^ = 2.671, 95% CI = 1.246 ~ 5.728) was an independent risk factor, men are more prone to bleeding than women; it was a protective factor for the location of polyps is sigmoid colon compared to rectum (P = 0.011, OR^ = 0.348, 95% CI = 0.154 ~ 0.786), and it was a risk factor for the polyps whose diameters ≥ 3.0 cm compared to among 1.0 ~ 1.9 cm. Univariate analysis of the features for carcinogenesis of colorectal adenomatous polyps, we found that surface lobulated or not (P = 0.001), surface smooth or not (P = 0.017), Yamada classification (P = 0.008) were statistically significant deviation, and the logistic regression analysis identified surface lobulation (P = 0.001, OR^ = 6.556, 95% CI = 2.326 ~ 18.475) was an independent risk factor for carcinogenesis of adenomatous polyps. Conclusion Resection of colorectal polyps under endoscope is a safe treatment method. Taking the polyp as observation unit, gender is an independent risk factor of colorectal polyps resected under endoscope on intraoperative and delayed bleeding, men are more prone to bleeding than women; the larger the diameters of polyps are, the higher the bleeding rates could be. Surface lobulation of colorectal adenomatous polyps are more likely lead to carcinogenesis.

BACKGROUND:Autologous platelet rich plasma and bone marrow mesenchymal stem cells have certain effects on bone repair,but there are rare reports on the clinical treatment of long shaft fracture bone nonunion using autologous platelet rich plasma combined with bone marrow mesenchymal stem cell transplantation.OBJECTIVE:To investigate the therapeutic effect of autologous platelet rich plasma combined with bone marrow mesenchymal stem cell transplantation on long shaft fracture bone nonunion.METHODS:Forty-seven patients with long shaft fracture bone nonunion were randomly divided into two groups:monotherapy group (n=22) and combination group (n=25).In the monotherapy group,autologous bone marrow mesenchymal stem cell transplantation was performed in the bone nonunion site.In the combination group,autologous platelet rich plasma combined with bone marrow mesenchymal stem cell transplantation was implemented in the bone nonunion site.Callus score,clinical healing time,local complications and limb function grade were recorded and compared between the two groups.RESULTS AND CONCLUSION:The healing properties and limb function in the combination group were significantly superior to those in the monotherapy group [healing time:(4.2±1.5) vs.(5.6±1.1) months,P ＜ 0.05;healing rate:92％ vs.86％,P ＜ 0.05;callus score:2.74±0.36 vs.2.32±0.53,P ＜ 0.05;limb function recovery rate:77％ vs.84％,P ＜ 0.05].Complications like local skin redness or infection were not found in the two groups.In conclusion,both of the two methods can promote bone healing,but autologous platelet rich plasma combined with bone marrow mesenchymal stem cell transplantation has a better clinical effect on bone healing.

This study was aimed to explore the clinical characteristics and optimal therapeutic methods for newly diagnosed acute promyelocytic leukemia (APL) combined with disseminated intravascular coagulation (DIC) so as to guide the clinical therapy. The clinical date and therapeutic outcome of 25 cases of APL combined with DIC treated from January 2008 to March 2013 in our department were analysed retrospectively. The 25 patients were given ATRA 20 mg orally twice a day and arsenic trioxide (ATO) 10 mg intravenously once a day to induce differentiation therapy, the chemotherapy was added after degranulation of promyelocytes. At the same time the platelets, fresh frozen plasma, fibrinogen, cryoprecipitate,prothrombin complex and amino methylbenzoic acid, low molecular weight heparin were given to treat DIC. According to the laboratorial examination of coagulation and fibrinolysis, the medication was adjusted.The white blood cell count, platelet level, prothrombin time (PT), partial thromboplastin time of plasma (APTT), fibrinogen level were detected, and the relation of those factors and age with bleeding severity was analyzed by multivariate manner. The results showed that among 25 patients with APL (low-risk 5 cases, intermediate risk 13 cases and high risk 7 cases), 22 cases combined with DIC, incidence of DIC was 88%. Out of 22 patients with DIC 21 patients (95.5%) were corrected, except 1 case death. After the first course of treatment, 23 cases (92%) gained complete remission (CR) with average CR time 31.8 ± 7.2 days. During the induction of CR, the average platelet transfusion level was 75.68 ± 55.88 U, the RBC level was 8.90 ± 5.69 U, the average level of fresh frozen plasma transfusion of APL patients with DIC was 21.92 ± 19.32 U. The recovery time of platelet level to normal was 29.3 ± 9.3 days, the recovery time of PT, APTT, FDP and fibrinogen to normal were 12.7 ± 9.5 days, 11.6 ± 8.6 days, 16.0 ± 9.3 days and 125.3 ± 85.3 days respectively. The multivariate analysis showed that WBC count at onset was >10 × 10(9)/L and APTT was prolonged. These two factors were main reasons resulting in severe bleeding. It is concluded that the newly diagnosed APL always combined with DIC, therefore in the early phase of disease active transfusion of blood products, application of anti-coagulation and anti-fibrinolytic drugs as well as heparin should be performed; the coagulation function should be as soon as recovered to normal so as to early correct DIC. These measures can significantly decrease the mortality of APL patients resulting from DIC. The hyperleukocytosis and prolonged APTT are the main factors for severe bleeding.

This study was purposed to investigate the clinical features, diagnosis, treatment and prognosis of elderly patients with acute myeloid leukemia (AML) (non-APL). The clinical data of 76 elderly ( ≥ 60 old years) AML (non-APL) patients from January 2000 to January 2010 were analyzed retrospectively. According to treatment methods,the 76 patients were divided into 2 groups: induction chemotherapy group (51 cases) and best supportive treatment group (25 cases). The patients in induction chemotherapy group received the cytarabine-based induction chemotherapy regimens, including DA, MA, HA, IA and CAG; the patients in best supportive treatment group received supportive treatment including hydroxyurea, blood transfusion and so on. The clinical features, diagnosis, treatment and prognosis between 2 groups were compared. The results showed that the median survival times of patients in induction chemotherapy and best supportive treatment groups were 5 (0.2-89) and 3 (0.1-17) months respectively, there was significantly statistical difference in median survival time between 2 groups(P < 0.01) suggesting that the induction chemotherapy obviously prolonged the survival time of elderly CML patients. The 5 patients in induction chemotherapy group survived more than 60 months, one of them survived more than nine years. After the first cycle of chemotherapy, the complete remission (CR) rate of patients was 19.6% (10/51), partial remission (PR) rate was 19.6% (10/51), the overall response rate (ORR) was 39.2%, the mortality of patients in induction remission stage was 13.7% (7/51) in induction chemotherapy group; no 1 case in best supportive treatment group reached to CR. The CR rate of patients by using MA regimen was 44.4% and its ORR was 55.5%, which was higher than that by using DA, HA, IA and CAG regimens. The median chemotherapy cycles were 3 (1-14). The follow-up found that the 3 months-survival rate of patients was 65% and 42%, the 6 month-survival rate of patients was 43% and 21%, the 1 year-survival rate of patients was 29% and 13%, the 5 year-survival rate of patients was 13% and 0% in induction chemotherapy and best supportive treatment groups respectively, showing that the survival of patients in induction chemotherapy group was better than those in best supportive treatment group. A total of 31 of out 51 cases (60.8%) in induction chemotherapy group not response to the first cycle of chemotherapy, the survival time of these patients was not statistically significantly different from that of patients in best supportive treatment group. It is concluded that the induction chemotherapy can significantly improve the prognosis of elderly patients with AML, and prolong their median survival time. The induction remission rate in elderly patients with AML is lower than that of younger patients. The MA regimen is better than DA, HA, IA and CAG, there is individual difference in the elderly patients with AML, If the first cycle of chemotherapy has not reached to CR or PR, the best supportive treatment may be considered. The low toxicity, efficient and well-tolerated chemotherapy regimens may be chosen to prolong the survival time of the elderly patients with AML (non-APL).

OBJECTIVETo evaluate the effect of FLAMIGEL (hydrogel dressing) on the repair of residual burn wound.

METHODSSixty burn patients with residual wounds hospitalized in 6 burn units from November 2011 to May 2012 were enrolled in the multi-center, randomized, and self-control clinical trial. Two residual wounds of each patient were divided into groups T (treated with FLAMIGEL) and C (treated with iodophor gauze) according to the random number table. On post treatment day (PTD) 7 and 14, wound healing rate was calculated, with the number of completely healed wound counted. The degree of pain patient felt during dressing change was evaluated using the visual analogue scale (VAS). The mean numbers of wounds with score equal to zero, more than zero and less than or equal to 3, more than 3 and less than or equal to 6, more than 6 and less than or equal to 10 were recorded respectively. Wound secretion or exudate samples were collected for bacterial culture, and the side effect was observed. Data were processed with repeated measure analysis of variance, t test, chi-square test, and nonparametric rank sum test.

RESULTSWound healing rate of groups T, C on PTD 7 was respectively (67 ± 24)%, (45 ± 25)%, and it was respectively (92 ± 16)%, (72 ± 23)% on PTD 14. There was statistically significant difference in wound healing rate on PTD 7, 14 between group T and group C (F = 32.388, P < 0.01). Ten wounds in group T and four wounds in group C were healed completely on PTD 7, with no significant difference between them (χ(2) = 0, P > 0.05). Forty-two wounds in group T and seven wounds in group C healed completely on PTD 14, with statistically significant difference between them (χ(2) = 42.254, P < 0.01). Patients in group T felt mild pain during dressing change for 37 wounds, with VAS score higher than zero and lower than or equal to 3. Evident pain was observed in patients of group C during dressing change for 43 wounds, and it scored higher than 3 and less than or equal to 6 by VAS evaluation. There was statistically significant difference in mean number of wounds with different grade of VAS score between group T and group C (Z = -4.638, P < 0.01). Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella pneumoniae, E. coli, Baumanii, and Staphylococcus epidermidis were all detected in both groups, but there was no statistical difference between group T and group C (χ(2) = 0.051, P > 0.05). No side effect was observed in either of the two groups during the whole trial.

CONCLUSIONSFLAMIGEL can accelerate the healing of residual burn wounds and obviously relieve painful sensation during dressing change.

BackgroundDry eye is a multi-factorial-induced tear film and ocular surface disorder.Immunoinflammation plays a key role in the pathogenesis of dry eye.As inhibitor of the cyclo-oxygenase pathway,nonsteroidal anti-inflammatory drugs play an anti-inflammatory and anti-hypersensitivity role,and it can be a potential treatment for dry eyes.ObjectiveThis study was to investigate the effectiveness of nonsteroidal anti-inflammatory drugs (0.1％topical pranoprofen) on moderate to severe dry eyes and its mechanism.MethodsThis was a small sample of randomized controlled clinical trial.Thirty right eyes of 30 patients with moderate to severe dry eyes were included in the study according to the diagnosis criteria and randomized into two groups.The patients of the trial group received topical administration of 0.1％ pranoprofen plus 0.1％ sodium hyaluronate,and those of the control group received the topical 0.1％ sodium hyaluronate only.Ocular surface inflammation index scores (OSDI) and ocular surface fluorescine staining (OSS) scores were measured under the slit lamp,and tear film break-up time (BUT),Schirmer Ⅰ test values were evaluated.The expression of human leucocyte antigen-DR (HLA-DR) and CD11b in conjunctiva epithelial cells were detected by impression cytology and flow cytometry (FCM).All the indexes were compared between the two groups before and after treatment.Informed consent was obtained from all patients.ResultsThere were no significant differences in terms of age and gender and their baseline values between the trial group and control group (t=0.412,P=0.684;x2=0.240,P=0.624),and so were all the indexes (P＞0.05).Compared with the control group,the OSDI,OSS scores and cells positive for HLA-DR were lowered but the BUT was delayed in the trial group on day 15 ( t=2.43,P=0.03;t=2.83,P=0.01;t=3.29,P=0.00;t=3.23,P=0.00 ).No significant differences were found in the Schirmer Ⅰ test value and CD11b expression between these two groups (t=0.17,P=0.87;t=0.28,P=0.79).The OSDI,OSS scores and BUT were significantly improved,and the number of cells positive for HLA-DR were reduced 15 days after administration of drugs in comparison with before treatment in the trial group ( t =12.30,10.70,6.10,7.92,P =0.00 ).However,there were no comparable alteration seen in these indexes before and after the usage of drugs in the control group ( P＞0.05).Positive correlations were found in HLADR expression with OSDI and OSS ( r =0.601,P =0.018 ; r =0.586,P =0.022 ) and a negative correlation in HLADR expression with BUT (r=-0.697,P=0.004) on day 15 in the trial group.ConclusionsTopical usage of 0.1％ pranoprofen is beneficial for remitting the ocular signs and symptoms in moderate to severe dry eyes.This study illustrates that topical usage of 0.1％ pranoprofen can down-regulate the expression of inflammatory markers in conjunctival epithelial cells.
