Objective To observe the therapeutic effect and prognosis of patients with severe traumatic craniocerebral injury treated by Lund program combined with Angong Niuhuang pill. Methods A prospective study was conducted. Forty-nine patients with severe traumatic craniocerebral injury were divided into two groups:combined treatment group (25 cases) and control group (24 cases). All the patients in the two groups received conventional therapy. Additionally, the combined treatment group was treated by the Lund program combined with Angong Niuhuang pill, the patients after admission into the intensive care unit (ICU), indwelling of gastric tube was immediately given (the tube inserted and retained through mouth in cases with cranial base bone fracture), one pill of Angong Niuhuang was fed nasally twice a day for consecutive 15 days. Before and after treatment, the intracranial pressure (ICP), cerebral perfusion pressure (CPP), Glasgow coma scale (GCS) score, the mean flow velocity of middle cerebral artery (MCA), and the incidence of complication, clinical efficacy and prognosis in the two groups were observed. Results There were no statistically significant differences in the levels of ICP, CPP, GCS score and the average flow velocity of MCA before treatment and the first day after treatment between the two groups. Beginning from 3 days after treatment, the degrees of improvement in the above indexes in the combination treatment group became much better than those in the control group [ICP (mmHg, 1 mmHg=0.133 kPa):16.78±4.50 vs. 18.80±5.67, CPP (mmHg):71.35±1.63 vs. 58.11±1.47, GCS score:9.53±0.38 vs. 8.23±0.44, the mean blood flow velocity (cm/s):152.23±3.33 vs. 178.86±5.23, all P<0.05]. The incidences of complications such as hyperpyrexia [8.0%(2/25) vs. 41.7%(10/24)], hyperspasmia [12.0%(3/25) vs. 45.8%(11/24)] and cerebral hernia [8.0%(2/25) vs. 33.3%(8/24)] in the combined treatment group were significantly lower than those in the control group (all P < 0.05). The rates of renal failure, electrolyte imbalance and pulmonary infection in combined treatment group were also lower than those in the control group, but the differences were not statistically significant (all P>0.05). The rate of good therapeutic effect in combination treatment group was obviously higher than that of the control group [72.0% (18/25) vs. 33.3% (8/24), P < 0.05], while the mortality was markedly lowered [8.0% (2/25) vs. 33.3% (8/24), P < 0.05]. Conclusions The combination of Lund program and Angong Niuhuang pills for treatment of patients with severe traumatic craniocerebral injury can reduce the degree of increase of ICP at early stage, ameliorate cerebral edema and its development, elevate CPP and improve cerebral ischemia and hypoxia. In the aspects of controlling hyperpyrexia, decreasing limbs twitches and the incidence of hernia, elevating the quality of patients' life, reducing mortality and improving prognosis, the therapy has relatively good therapeutic effects.

Objective To investigate the possibility of detection of the human papillomavirus (HPV)L1 capsid protein to predict the coarse of mild or moderate cervical intraepithelial neoplasia(CIN).Methods Immunocytochemical analysis using antibody against HPV L1 capsid protein was carried out on 274 samples obtained from women performed Tri Path Pap tests.positive for high-risk HPV DNA detected by hybrid capture Ⅱ (HC-Ⅱ)or cytologic diagnosed atypical squamous cells of undetermined significance (ASCUS)or more severe.For cytological diagnosed,there were ASCUS 105 cases,low-grade squamous intraepithelial lesions (LSIL) 119 cases,atypical squamous cells cannot exclude high-grade squamous intraepithelial lesion (ASC-H)9 cases,high-grade squamous intraepithelial lesions(HSIL)36 cases,and squamous cell carcinoma(SCC)5 cases.But for the pathologic diagnosed,there were chronic cervicitis 96 cases.CIN Ⅰ 55 cases,CIN Ⅱ 55 cases,CIN Ⅲ 32 cases,and SCC 6 cases.Results Of the 274 cases,HPV L1 capsid protein was positive in 69.8%(67/96) of cervicitis,83.5%(71/85)of CIN Ⅰ,41.8% (23/55)of CIN Ⅱ,3.1%(1/32)of CIN Ⅲ and 0(0/6)of SCC.Cytologic diagnosis revealed a higher expression rate in LSIL(75.6%.90/119) than that in ASCUS(63.8%,67/105)or in HSIL + SCC (9.8%,4/41;all P<0.01).Of 71 cases with ASCUS and ISIL without treated,none of HPV L1 positive cases(0/55)progressed in cytology,while 19%(3/16)of HPV L1 negative cases progressed to ASC-H,HSIL(P<0.01).Conclusion The expression rates of HPV L1 protein in liquid-based cell specimen is decreased as the cytopathology diagnosis severe degree.which may imply the histopathology diagnosis of cervix,predict the progression of cervical lesion,and help to treat the cases with ASCUS and LSIL.

Objective To explore the changes of expression of tight junction protein occludin in the brain microvascular endothelial cells of rats with acute necrotizing pancreatitis (ANP), and to study the relationship between the occludin expression and degree of pancreatic pathologic changes. Methods 80 rats were randomly divided into sham-operation (SO) group and ANP 3 h, 6 h, 12 h, and 24 h groups. Retrograde pancreatic duct injection of 5% choleate sodium in rats was used to establish ANP models. Pancreatic pathologic changes was evaluated. Immunohistochemistry, Western blot and RT-PCR were used to determine the expressions of the tight junction protein occludin in the brain microvascular endothelial cells. Results Occludin protein was linearly expressed along brain vascular vessels. The expression of occludin protein at 3h was 0. 35±0.09 in brain tissues from rats with ANP and 0. 49±0.08 in SO group, the expression of occludin mRNA were decreased from 1.50±0.30 to 1.01±0.18 (P < 0.05), the lowest expression rate occurred at 6 h, and the values in the two groups were 0. 26±0.07 and 0. 93±0. 19, respectively, the expressions of occludin protein and mRNA of ANP group at 12 h, 24 h were notably increased when compared with those at 6 h (P < 0. 05), but they were still lower than those in SO group (P < 0.05). The occludin protein and mRNA expressions were negatively related with the degree of pancreatic pathologic changes (Pearson correlation coefficient: -0.48 and -0.536, P < 0.05). Conclusions The expression of tight junction protein occludin decreased at both protein and mRNA level in brain microvascular endothelial cells of ANP rats. Furthermore, the expression of occludin was negatively correlated with pathological change of pancreas.

Objective To investigate the short?term complications and cosmetic outcomes of radiotherapy in breast conserving surgery for early?stage breast cancer. Methods A retrospective analysis was performed on clinical data from 30 patients with early?stage breast cancer from 2013 to 2015. All patients underwent breast conserving surgery combined with intraoperative low?energy X?ray radiotherapy. The prescribed dose was 20 Gy at the surface of the applicator. Local complications, radiation injury, and cosmetic outcomes were observed after surgery. Results No grade 3?4 adverse reactions were found in patients. In terms of short?term complications, four patients (13%) had seroma, two of whom needed suction treatment;three patients ( 10%) had grade 1?2 skin erythema. Half of the patients had excellent cosmetic outcomes. None of the patients had local recurrence or distant metastasis. Conclusions Intraoperative low?energy X?ray radiotherapy is safe and feasible in breast conserving surgery for breast cancer. It can be considered as an optional approach for tumor bed boost in some patients with early?stage low?risk breast cancer.
