Objective To investigate the effects of AFP enhancer/pgk promoter driven expression of the dominant negative form of the PP2A catalytic subunit α (DN-PP2Acα) in vivo.Methods The previously constructed AFpg promoter-driven DN-PP2Acα was recombined into an adenovirus,and the expression of PP2Ac was tested using Western blot.Cell growth was tested using the MTT and flat plate clone formation assays.In vivo studies were performed in tumor xenograft models.Results AFpg promoter-driven expression of DN-PP2Acα exerted cytotoxic effects against the AFP-positive human hepatoma cell line HepG2,but did not affect AFP-negative human hepatoma cells (SKHEP-1) or normal human liver cells (L-02).Moreover,AFP enhancer/pgk promoter driven expression of DN-PP2Acα inhibited the growth of AFP-positive HepG2 tumors in nude mice bearing solid tumor xenografts,but did not affect AFP-negative SK-HEP-1 tumors.Conclusion The recombinant AFP enhancer/pgk promoter-driven DN-PP2Acα expression adenovirus presented selective cytotoxicity against AFP-positive hepatoma cells and provides a useful gene therapy strategy to selectively target hepatocellular carcinoma.

Objective To improve the understanding of pulmonary mucormycosis by analyzing the clinical manifestations,imaging features,diagnosis,treatment and prognosis of this disease.Methods The clinical data of eight patients diagnosed as pulmonary mucormycosis by histopathologic examination were retrospectively analyzed.Results Eight patients included six males and two females with age from 36 days to 66 years.Underlying conditions covered diabetes (n =4),renal transplantation (n =3),premature (n =1) and long-term corticosteroid treatment in two cases.Imaging manifestations revealed multiple irregular lumps or nodules in three cases,multiple cavities with thick wall in three cases,diffuse lung infiltrate in one case and lung opacities in one case.The diagnoses of seven patients were confirmed by percutaneous needle lung biopsy and the remaining one was diagnosed with fiberoptic bronchoscopy biopsy.Surgery combined with amphotericin B liposome(60 mg/d for three weeks)was applied to one patient who was cured with no recurrence after a 22 month follow-up.Three cases were given amphotericin B liposome (a newborn with 7mg/d for 62 days,the other two 60 mg/d for 31 days and 70 mg/d for 71 days respectively).All had achieved marked response with follow up from 8 to 29 months,but one patient relapsed and died of recurrent lung mucormycosis.The other three patients were treated with itraconazole 400-200 mg/d from 21 days to 1 year with duration of follow up from 1 month to 20 months.One patient was not evaluable due to missing.Two patients relapsed and one died.Conclusion Pulmonary mucormycosis is difficult to diagnose and treat with a high mortality.Percutaneous tranthoracic lung biopsy is a useful diagnostic method.Amphotericin B liposome or itraconazole may be active against mucus.Early control of causes is essential to improve the prognosis and reduce the recurrence in patients with pulmonary mucormycosis.

Objective To analyze the clinical data of male breast cancer (MBC),and investigate the clinical characteristics and factors potentialy affecting prognosis of male breast cancer. Methods A retrospective case-control study was performed on 17 MBC and 102 female breast cancer cases from January 1996 to 2008, treated in the hospital with pathologic proofs. Results MBC accounted for 1.15% (17/1473) of all cases. The initial visiting age was older, the time from the appearance of lump to the first doctor contact was longer, the positive rate of axiUary lymph node metastasis and local skin change incidence ratio was higher in the male group (P <0.05); there was no significant difference about overall 5-year disease-specific survival between the two groups (P >0.05), when tumor stages and nodal involvement were checked, Conclusion This study suggests that the two groups' prognosis is similar, the gender is uncertain prognostic factor.

Objective To investigate the risk of death between older and non-older critical patients in intensive care unit (ICU) in Shuyang People's Hospital.Methods A retrospective cohort study was conducted. The critical patients who aged 15 or above, and admitted to ICU of Shuyang People's Hospital from January 2014 to December 2016 were enrolled, and all the data was collected from theregistration and electronic medical records in the ICU. The prevalence and causes of death in ICU critical patients during the study period were observed. The patients were divided into elderly group (65 years and older) and non-elderly group (15-65 years), and logistic regression analysis was performed for the risk of death in the two groups.Results During the study period, 2707 critical patients in emergency were admitted to the ICU of Shuyang People's Hospital, and patients not satisfied the inclusion criteria were excluded. Finally, a total of 2466 patients were enrolled in the analysis with the male and female ratio of 1.6 : 1, an average age of (61.8±17.3) years, a median Glasgow coma scale (GCS) score of 6 (4, 8), and with a median ICU stay of 3 (1, 6) days. In 2466 critical patients, the most common cause of critical state was spontaneous intracerebral hemorrhage (25.5%) and traumatic brain injury (17.0%), with a fatality rate of 46.0% and 39.5% within first 7 days respectively. Compared with the non-elderly patients (n = 1415), the incidences of death of the elderly patients (n = 1051) due to traumatic brain injury, cerebral infarction, heart failure/cardiovascularcrisis, and respiratory critically ill were significantly increased (9.4% vs. 4.7%, 2.9% vs. 0.8%, 5.0% vs. 2.1%, 2.5% vs. 1.0%, respectively), while the incidence of death for pesticide/drug poisoning in the elderly group was significantly lower than that in the non-elderly group (0.2% vs. 1.2%, allP < 0.01). Stepwise logistic regression analysis showed that traumatic brain injury [hazard ratio (HR) = 1.878, 95% confidence interval (95%CI) = 1.233-2.864,P = 0.003), cerebral infarction (HR = 0.435, 95%CI = 0.229-0.826, P = 0.011), heart failure/cardiovascular crisis (HR = 0.399, 95%CI = 0.238-0.668,P = 0.000), and respiratory critically ill (HR = 0.239, 95%CI = 0.126-0.453,P= 0.000) in the older patients were significantly high risk factors of death as compared with those in non-older patients.Conclusions In the general ICU, the most common cause is spontaneous intracerebral hemorrhage and traumatic brain injury in critical patients with a high fatality rate. The risk of death in elderly patients with severe traumatic brain injury, cerebral infarction, heart failure/cardiovascular crisis, respiratory critically ill is higher than that of the non-elderly patients.

Objective:To observe the curative effect and temperature safety management of ginger mud moxibustion of different thickness on ankylosing spondylitis patients with kidney yang deficiency type, and to explore the best curative effect combination and safety combination of ginger mud thickness in Du Meridian moxibustion.Methods:From March 2020 to March 2021, 90 patients with ankylosing spondylitis of kidney yang deficiency type who were treated with Du moxibustion in the Affiliated Hospital of Nanjing University of Chinese Medicine were selected. According to the thickness of ginger paste, they were randomly divided into 2 cm-thick ginger mud thickness group, 3 cm-thick ginger mud thickness group and 4 cm-thick ginger mud thickness group when the diameter and height of moxa wool were the same as 2 cm, 30 cases in each group. They were treated with Fu Yang Du moxibustion once a week for 60 minutes each time. Visual Analogue Scale (VAS), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI), traditional Chinese medicine syndrome score were used to evaluate the curative effect of spinal function before and after the intervention for 6 weeks. The time when moxibustion temperature reached 43 ℃ and moxibustion temperature maintained at 43-45 ℃ were analyzed for safety evaluation.Results:After moxibustion, VAS scores of 2 cm-thick ginger mud thickness group, 3 cm-thick ginger mud thickness group and 4 cm-thick ginger mud thickness group were 2.89 ± 0.96, 2.01 ± 0.69, 2.93 ± 1.23, BASDAI scores were 3.51 ± 0.94, 2.69 ± 0.68, 3.13 ± 0.96 and BASFI scores were 1.71 ± 0.99, 0.99 ± 0.36, 1.61 ± 0.50, the traditional Chinese medicine syndrome scores were 15.97 ± 4.61, 12.08 ± 3.21, 13.79 ± 3.58. The scores of the three groups were statistically significant ( F values were 6.51-19.22, all P<0.05) . After the intervention, there were significant differences in the scores between 2 cm-thick ginger mud thickness group and 3 cm-thick ginger mud thickness group, 2 cm-thick ginger mud thickness group and 4 cm-thick ginger mud thickness group, 3 cm-thick ginger mud thickness group and 4 cm-thick ginger mud thickness group ( t values were -6.61-4.56, all P<0.05). Conclusions:Du moxibustion is an effective method to treat ankylosing spondylitis of kidney yang deficiency type. The best curative effect and safety combination is moxa velvet diameter height 2 cm, ginger mud thickness 3 cm.

Objective: To investigate the prognostic value of pretreatment albumin to globulin ratio(AGR)in prostate cancer(Pca)patients treated with maximal androgen blockade(MAB). Methods: Clinical and pathological data of 210 Pca patients who underwent MAB as first-line therapy between January 2013 and June 2018 were retrospectively analyzed.The ages of patients in our cohort ranged from 61 to 90 years, with a mean of(77.0±6.5)years.According to the cut-off point for AGR calculated by the receiver-operating curve analysis, patients were categorized into two groups: the high-AGR group and the low-AGR group.Clinical and pathological features were compared between the groups.Independent factors affecting prognosis were analyzed by using univariate and multivariate analysis. Results: The median follow-up duration was 44.0 months.Of the 210 patients, 99 cases had castration resistance, 100 patients(47.6%)had disease progression and 67 patients(31.8%)died.The cut-off point for AGR calculated by the receiver-operating curve analysis was 1.56.There were 103 cases in the low-AGR group(AGR<1.56)and 107 cases in the high-AGR group(AGR≥1.56). Univariate analysis revealed that the progression-free survival(PFS), cancer-specific survival(CSS)and overall survival(OS)were lower in the low-AGR group than in the high-AGR group[1.773(1.298~2.442), 1.948(1.220~3.213), 1.965(1.217~2.996), all P<0.05]. Multivariate Cox regression analysis showed that Gleason score, regional lymph nodes and bone metastases and AGR were independent prognostic factors for PFS(P=0.007, 0.040 and 0.022, P=0.031), CSS(P=0.003, 0.035 and 0.041, P=0.009)and OS(P=0.003, 0.026 and 0.023, P=0.002). Conclusions Pretreatment AGR<1.56 is an independent predictor for poor prognosis in Pca patients treated with MAB.

Objective:To investigate the emergency surgical effect of ruptured intracranial dural arteriovenous fistula (DAVF).Methods:Patients with ruptured intracranial DAVF underwent microsurgery in the Department of Neurosurgery, Nanping First Hospital Affiliated to Fujian Medical University from May 2013 to July 2022 were retrospectively included. The clinical, imaging and follow-up data were collected, and the clinical characteristics, selection of surgical methods and treatment effects of patients were summarized.Results:A total of 8 patients with DAVF were enrolled. Their age ranged from 11 to 60 years (average, 48 years). There were 7 males and 1 female. All 8 patients suffered from intracranial hemorrhage, manifested as headache and vomiting in 2 cases, simple conscious disturbance in 2 cases, conscious disturbance with cerebral hernia in 3 cases, and conscious disturbance with limb paralysis in 1 case. The fistula was located in the anterior fossa in 4 cases (including 2 cases with aneurysms), the middle fossa in 2 cases (including 1 case with moyamoya disease), the transverse sinus in 1 case, and the anterior 1/3 area of the sagittal sinus in 1 case. Cognard classification: 7 patients were type Ⅲ and 1 was type Ⅳ. After admission, all patients underwent emergency craniotomy and microsurgery to remove hematoma. Among them, 4 patients underwent decompressive craniectomy at the same time, 1 patient with moyamoya disease underwent dural turnover and temporalis muscle application at the same time, and 2 patients with aneurysms at the same location were clipped at the same time. Postoperative re-examination of head CT showed that the hematoma was cleared satisfactorily and the midline was no shift in all 8 patients. CT angiography (CTA) showed that the fistula disappeared within 2 weeks. Seven patients were followed up within 1-12 months after operation. CTA or digital subtraction angiography showed no recurrence of DAVF. Two patients with aneurysms did not have residual or recurrent aneurysms. All patients had no new neurological symptoms, and the Glasgow Outcome Scale score in 2 patients increased by 1 compared with that at discharge.Conclusion:Emergency microsurgery is an effective method for the treatment of ruptured intracranial DAVF, especially for patients with special parts or complicated hematoma, cerebral hernia, and other vascular diseases.
