OBJECTIVE:
In order to investigate the interaction between the cytokines and keratinocyte and determine the role of cytokines in hyperproliferative of chronic otitis media with cholesteatoma, we observe the expression of matrix metalloproteinase 9 (MMP9), vascular endothelial growth factor (VEGF), keratinocyte growth factor (KGF) and its receptor (KGFR) in middle ear cholesteatoma.
METHOD:
We examined the expression of MMP9, VEGF, KGF, KGFR and Ki-67 by immunohistochemistry in 50 specimens from chronic otitis media with cholesteatoma and 15 specimens from the normal skin of external auditory meatus. Ki-67 as an evaluation of cholesteatoma proliferation markers were used to detect the keratinocyte proliferative activity.
RESULT:
(1) The expression of VEGF and MMP9 in cholesteatoma specimens was higher than normal skin, and the difference was statistically significant (t = 4.914, P < 0.01; t = 3.284, P < 0.01). (2) The expression of KGF and KGFR in middle ear tissues was higher than normal skin, and the difference was statistically significant (t = 4.814, P < 0.01; t = 3.104, P < 0.01); The expression of KGF and KGFR increased, and the expression of Ki-67 also correspondly increased in the cholesteatoma. (3) In the tissue MMP9 and VEGF were positive. Mean optical density increased as well. KGF expression also increased accordingly.
CONCLUSION
MMP9, VEGF, KGF and KGFR proteins played an important role in hyperproliferation of cholesteatoma tissues. VEGF, MMP9 and KGF had a synergistic effect in hyperproliferation of cholesteatoma tissues.

Objective:To introduce our experience in the treatment of infection related to lower long bone fracture in adults.Methods:From January 2017 to December 2020, 31 adult patients with infection related to lower long bone fracture were treated at Department of Orthopaedics, the 7th Medical Center, General Hospital of the People's Liberation Army. They were 20 males and 11 females with an age of (35.7±16.7) years. There were 9 cases of acute infection, 3 cases of delayed infection and 19 cases of late infection. They were treated according to their stage of infection, respectively, by retaining or removing the internal fixation, debridement, bone grafting and bone lengthening. They were followed up regularly for at least 12 months to observe their symptoms, signs, indexes of imaging and blood tests. Paley score for fracture union was recorded at the last follow-up.Results:All the 31 patients were followed up for 13.0(13.0, 31.0) months. Of the 9 patients with acute infection, 6 retained the implant, 1 removed the implant for dressing change due to intolerability and 2 removed the implant due to unsatisfactory infection control. Of the 3 patients with delayed infection, 1 retained the implant and 2 removed the implant because of unsatisfactory infection control. Of the 19 patients with delayed infection, 5 were treated with local bone graft, 6 with Masqulet technique and 8 with bone transfer following debridement and implant removal. All patients were cured without recurrence of infection. According to Paley's scoring, 25 cases were excellent, 5 were good, and 1 was fair.Conclusions:Treatment of infection related to lower long bone fracture in adults should be carried out according to its clinical stage. For acute and delayed infection, implants should be preserved as much as possible; for chronic infection, implants should be removed to perform bone and soft tissue reconstruction after thorough debridement. Personalized diagnosis and treatment protocols can lead to satisfactory clinical results.

Purpose:
The present study investigated the association between Systematic COronary Risk Evaluation (SCORE)-estimated cardiovascular risk and carotid stiffening in a middle-aged population using ultrafast pulse wave velocity (ufPWV).
Methods:
This study enrolled 683 participants without known cardiovascular disease or diabetes mellitus who underwent ufPWV measurements. Clinical interviews, physical examinations, laboratory findings, carotid intima-media thickness (cIMT), pulse wave velocity (PWV) at the beginning of systole (PWV-BS), and PWV at the end of systole (PWV-ES) were assessed. Each participant underwent an assessment of SCORE risk based on major cardiovascular risk factors (CVRFs), including age, sex, smoking, systolic blood pressure (SBP), and total cholesterol (TC). Crude and adjusted odds ratios (ORs) with 95% confidence intervals and ordinal logistic regression were used. Overall CVRFs were adjusted to assess ORs.
Results:
cIMT and carotid stiffening in PWV-BS and PWV-ES were significantly different between sex subgroups (all P<0.05), but only PWV-ES increased gradually in age and SCORE-estimated risk subgroups (all P<0.05). Compared with cIMT (r=0.388, P<0.001) and PWV-BS (r=0.159, P<0.001), PWV-ES was more strongly correlated with SCORE categories (r=0.405, P<0.001). Higher PWV-ES values were associated with SCORE categories independently of sex, SBP, TC, and smoking in moderate-risk and high-risk subgroups (OR, 1.63; P<0.001 and OR, 2.12; P=0.024, respectively), but were not independent of age in all risk subgroups (all P>0.05).
Conclusion
Carotid stiffening quantified by ufPWV is linked to SCORE categories, and elevated PWV-ES may aid in cardiovascular risk stratification.

"Reinforcing earth for generating metal" is based on the treatment principle of the five-element theory of traditional Chinese medicine (TCM), which states that "reinforcing mother viscera for treating deficiency of child viscera". Based on the principle of inter-generating relationship in the five elements that earth generates metal, by strengthening the functions of the internal organs belonging to "earth" (spleen and stomach) to indirectly nourish the internal organs belonging to "metal" (lungs and large intestine). Using reinforcing earth for generating metal in the treatment of lung cancer, according to the principle of "reinforcing mother viscera for treating deficiency of child viscera", by strengthening the function of "earth" viscera, the treatment effect of "metal" viscera can be achieved. The metabolic disorder, inflammatory response, and immune regulation caused by the changes in the composition and structure of intestinal microbiota are involved in the occurrence and development of lung cancer, which is consistent with the theory of “the external and internal relationship between the lung and the large intestine” in TCM. From the perspective of intestinal microbiota microecology, the paper discusses the pathogenesis of "earth disease leads to metal disorders" that the gut microbiota dysbiosis causes lung cancer and the treatment method of "reinforcing earth for generating metal" by regulating the microecological balance of gut microbiota in lung cancer, suggesting the great significance of "reinforcing earth for generating metal" therapy aiming at microecological balance of gut microbiota in the treatment of lung cancer, in order to provide a different perspective for the treatment of lung cancer with TCM.

The combination of the immunotherapy (i.e., the use of monoclonal antibodies) and the conventional chemotherapy increases the long-term survival of patients with lymphoma. However, for patients with relapsed or treatment-resistant lymphoma, a novel treatment approach is urgently needed. Chimeric antigen receptor T (CAR-T) cells were introduced as a treatment for these patients. Based on recent clinical data, approximately 50% of patients with relapsed or refractory B-cell lymphoma achieved complete remission after receiving the CD19 CAR-T cell therapy. Moreover, clinical data revealed that some patients remained in remission for more than two years after the CAR-T cell therapy. Other than the CD19-targeted CAR-T, the novel target antigens, such as CD20, CD22, CD30, and CD37, which were greatly expressed on lymphoma cells, were studied under preclinical and clinical evaluations for use in the treatment of lymphoma. Nonetheless, the CAR-T therapy was usually associated with potentially lethal adverse effects, such as the cytokine release syndrome and the neurotoxicity. Therefore, optimizing the structure of CAR, creating new drugs, and combining CAR-T cell therapy with stem cell transplantation are potential solutions to increase the effectiveness of treatment and reduce the toxicity in patients with lymphoma after the CAR-T cell therapy.
