Objective:To investigate the method for treating facial post-burn hyperpigmentation. Methods: Forty-two patients with facial post-burn hyperpigmentation were randomly divided into two groups.Twenty-four subjects applied 15% Azelaic Acid cream combined with 0.025% Tretinoin cream daily to face,and eighteen subjects applied vehicle cream.At base line and six weeks of treatment,each subject's facial hyperpigmentation was assessed by area and colorimetric evaluations.Results:The facial post-burn hyperpigmentation of the Azelaic Acid and Tretinoin-treated subjects were significantly lighter after six weeks of therapy than those of the vehicle-treated subjects(?~(2)=10.94,P

Absent in melanoma 2 (AIM2) is a cytoplasmic protein, which can identify and combine with the cytoplasmic dsDNA to activate caspase-1, and promote the maturation and release of IL-1β and IL-18, or induce pyroptosis.AIM2 belongs to the innate immune system and is the first line of defense to protect the body against the invasion of alien microbes.After identifying the pathogenic microorganisms, the activation of the host signal caused the reaction, which started microorganisms.The activation of the host signal caused the reaction, which started the innate immune and acquired immune response.Research also suggests that AIM2 plays an important role in the occurrence and development of tumor, which was abnormally expressed in many malignant tumors such as prostatic cancer, colorectal cancer, breast cancer, nasopharyngeal carcinoma, oral squamous cell carcinoma, non small cell lung cancer, and AIM2 plays different roles in the progression of different tumor.This article will summarize the research progress of AIM2 in innate immunity and tumor development.

Objective To clarify the frequency, the routes of transmission from mother to infant, the correlation factors and distribution of genotypes of transfusion transmitted virus (TTV) infection. Methods Nested polymerase chain reaction (n PCR) was performed to detect TTV DNA and genotypes in serums and breast milks from 160 cases of pregnant women. Results TTV DNA in serum and breast milk was detected in 64 (40 0%) and 60 (37 5%) of 160 cases of pregnant women respectively. The positive rates of TTV DNA from HBV markers (+) and normal groups were 50 0%, 43 1% and 13 6%, 22 7% respectively in serums and breast milk. There were significant difference between the two groups ( P

Objective: To investigate the clinical characteristics of medial medullary infarction (MMI) and their relationship with vascular lesions. Methods: Eighteen patients with clinical symptoms of MMI and confirmed by magnetic resonance imaging (MRI) were selected. Among them, 10 were performed head CTA examination, and 4 were performed cerebral panangiography. The clinical and imaging findings and the outcomes were observed. Results: Circled digit oneAmong the 18 patients, the lesions in 6 patients only affected the medial-ventral part of medulla (mainly causing contralateral limb movement disorder), in 2 patients affected the central part of medulla oblongata (mainly causing sensory dysfunction), and in 4 patients affected the dorsal side of medulla oblongata (mainly causing nystagmus and dizziness). The whole medial medulla were injured in the remaining 6 patients. Circled digit twoThe lesions were detected in 15 patients on T1WI, T2WI, and DWI sequences. The lesions were only detected in 2 patients on T2WI sequence. One patient showed equal signal on T1WI, T2WI, and a lesion was detected on T2WI one week after MRI reexamination. Circled digit threeAmong the 18 patents with MMI, 8 were complicated with diabetes. Six of them performed CTA/DSA examinations, and no vertebral artery lesions were detected. Ten patients were not complicated with diabetes (all with hypertension and elevated low-density lipoprotein), and 8 of them performed CTA/DSA examinations, and the vertebral artery lesions were detected in 7 patients. Conclusions: MMI mainly damages the ventral part of medulla oblongata. MRI is a preferred method at present in the diagnosis of medullary infarction. Diabetes causes small vascular disease and vertebral artery disease may participate the pathogenic process of MMI.
