The infratemporal fossa abscess is an irregularly shaped cavity, situated below and media to the zygomatic arch. It consists of masseter and nervus vascularis, etc. Comparatively speaking, the low position of the infratemporal fossa has almost freed the patient from dental, nasal,ocular and aural source of pain. So facial acupuncture is more likely to cause the infection. But it is also possible that the patient get cryptogenic infection of maxillofacial cavity, the treatment of which needs further study.

Objective To investigate the charateristics of pathological changes in hippocampal subregions in rats with epilepsy induced with different doses kainic acid(KA) ,discuss the etiology and pathway of epileptic wave.Methods 30 male Wistar rats were randomly divided into control group,low(0.025 ?g) and high(0.1 ?g) dose KA injection groups with 10 rats each.KA was focally injected into the right amygdala by a glass micropipette connected to an air pressure system to make epilepsy model.The pathological characteristics in hippocampal subregions in rats with epilepsy induced with different doses KA were observed.Results Compared with control group,high dose KA injection mainly caused neuron loss in the CA3 region,while pyramidal and dentate granule cells were evenly distributed with normal shape and size.Low dose KA injection caused severe damage in both CA1 and CA3 regions.Dentate granule cells didn't show any pathological change and neuron loss in low dose injection.Conclusion The pathological changes in hippocampal subregions in rats with epilepsy induced with KA are different with different doses KA,it might be related to the pathway of epileptic wave and the specific properties of hippocampus.

?Dry eye is a multi-factorial disease of tear film and ocular surface, and it can result in discomfort, visual disturbance and tear film instability and potential damage of ocular surface, accompanied by hyper osmolarity of tears and ocular surface inflammation. lnflammation is the key factor to dry eye. Many kinds of immune cells and inflammatory factors are involved in the occurrence and development of dry eye syndrome. Cell apoptosis, nerve dysregulation, disorders of sex hormones also play an important role in pathologic process of dry eye. Recently, while illustrating the pathophysiology and pathogenesis of dry eye has been made some progress, there is still no single standard. The possible mechanisms of ocular surface inflammation and tear dysfunction of dry eye were reviewed in this article.

Objective To investigate the expression of connexin CX43 using hybridization techniques after GABA restraining receptor gene was transferred into the supramammillary of hypothalamus in Kainic acid(KA) induced epileptic rats.Methods Twenty-four male Wistar rats were divided into four groups: control group(n=2),surgery group(n=2),KA group(n=10) and GABA restraining receptor gene transferred group(GABA group)(n=10).No treatment was given to the control group.Physiological saline(1 ?L) was injected into right amygdala of rat in surgery group.In KA group,KA(1 ?L,1 ?g) was injected into the amygdala of rat to build epileptic model.In GABA group,the GABA restraining receptor gene(400 nL,40 ng) was transferred into the supramammillary of hypothalamus by HVJ-liposome 48 h before KA was injected into amygdala.The expressions of CX43 mRNA and morphological changes different time(3 h,6 h,24 h,3d,7d) were observed by in situ hybridization in each group.Results In control group and surgery group,the morphological manifestations were normal,and the hippocampus structures were complete.In KA group,swell and degenerative hippocampus neurons were showed and deteriorated with time.In GABA group,the degeneration and necroses of hippocampus neurons were relatively alleviated.The positive expression of CX43 mRNA was few in control group and surgery group.And in KA group it increased with time.In GABA group,the positive expression of CX43 mRNA was fewer than that of KA group at every period.Conclusion The expression of CX43 mRNA in hippocampus can be decreased by transferring GABA receptor gene into hypothalamus.

PurposeTo analyze the sonographic and the histological features of special types of breast malignant tumors in order to explore preoperative ultrasound diagnosis. Materials and Methods Seven cases of special types of breast malignant tumors confirmed by pathology were retrospectively investigated by ultrasound. The sonographic and histological features of the lesions were reviewed. The ultrasonogram manifestations of the breast anatomy and the lesions were observed and recorded.Results Among 7 cases, there were 2 cases of papillary carcinoma, 3 cases of mucinous carcinoma, and 2 cases of lymphoma. Microscopically, the papillary carcinoma had clear boundaries with infringing mesenchyme, and the tissues were papillary and dense. The mucinous carcinoma had cancer cells floated in mucus lake. The primary breast lymphoma was diffused large B-cell type with focal lesion. For sonography type of breast, there were 3 cases of fatty types, 1 case of fibroglandular-1 and 3 cases of fibroglandular-2. The papillary carcinoma was hypoechoic in 2 cases, one of them was expansive growth with large size. Two cases of mucinous carcinoma were hypoechoic without accompanying sound attenuation in 1 case and with accompanying acoustic shadow due to calcification in the other case. Lymphoma was apparent anechoic and cystoid.Conclusion Special types of breast malignancies have different sonographic features and histological features from the common invasive ductal carcinoma. It has high clinical significance to enhance the understanding of rare malignant breast tumors.

Objective To investigate prognostic factors in patients with primary central nervous system diffuse large B-cell lymphoma (PCNS-DLCBL).Methods The clinical data of 71 patients with PCNS-DLCBL confirmed by pathology and clinical tests, who were admitted to our hospital from 1991 to 2015, were retrospectively analyzed.All patients received chemotherapy, mainly with high-dose methotrexate (HD-MTX, 66/71), and 59 patients received radiotherapy, mainly with whole brain radiotherapy (WBRT)±local boost.The Kaplan-Meier method was used to calculate survival rates, the log-rank test was used for survival comparison and univariate prognostic analysis, and the Cox model was used for multivariate prognostic analysis.Results Fifty-eight patients achieved a complete response (CR), ten achieved a partial response (PR), and three had progressive disease (PD).The 5-year overall survival (OS) rate was 43%, and the 5-year progression-free survival (PFS) rate was 34%.The univariate analysis showed that the factors associated with OS included the following:age of onset, Karnofsky Performance Scale (KPS) score, single or multiple lesions, whether to receive radiotherapy, evaluation results after radiotherapy and chemotherapy, and the presence or absence of recurrence (P=0.000-0.047);the multivariate analysis showed that the three factors that affected OS were age of onset, KPS score, and the presence or absence of recurrence (P=0.000-0.022).The univariate analysis revealed that chemotherapy regimen, whether to receive radiotherapy, total radiotherapy dose, WBRT dose, evaluation results after radiotherapy and chemotherapy, and the presence or absence of recurrence were the factors associated with PFS (P=0.000-0.028);the multivariate analysis revealed that KPS score and the presence or absence of recurrence were associated with PFS (P=0.000-0.011).Conclusions Among patients with PCNS-DLCBL, younger age, higher KPS score, and no recurrence are associated with better OS, and single lesion, radiotherapy, and better evaluation results after radiotherapy and chemotherapy may be associated with better OS;higher KPS score, better evaluation results after radiotherapy and chemotherapy, and no recurrence are the factors associated with better PFS, and HD-MTX chemotherapy, radiotherapy, higher total radiotherapy dose, and higher WBRT dose may be associated with better PFS.Whether to receive radiotherapy after achieving a CR with chemotherapy and the target area and dose of radiotherapy need to be further studied.

Objective To explore the effectiveness of the timed up and go test (TUGT) and the maximum walking speed test (MWST) in evaluating stroke patients' motor function.Methods Twenty-two stroke patients were assessed using the TUGT and MWST,and the temporal-spatial parameters of their gait were also assessed.The correlations among the TUGT times,walking speed and the gait parameters were quantified using Pearson correlation coefficients.Results The TUGT time was (18.57±7.41) s,significantly correlated with step length and velocity (P＜0.05).Walking speed showed a significant positive correlation with step length,velocity and step length (P＜ 0.05).The TUGT times were negatively correlated with walking speed (r=-0.712,P=0.000).Conclusion The MWST and TUGT both can assess stroke patients' motor function effectively.
