OBJECTIVETo compare the therapeutic effects of aspiration via a directional soft tube and conservative treatment in patients with mild hemorrhage in the basal ganglion.

METHODSSeventy-five patients with mild cerebral hemorrhage (10~30 ml) were randomly divided into two groups for aspiration treatment with minimally invasive directional soft tube placement (minimally invasive group, n=36) and conservative treatment (medication group, n=39). The patients in the two groups had comparable mean GCS scores of 11-15 on admission. The clinical outcomes of the patients were compared between the two groups.

RESULTSIn the minimally invasive group, complete removal or absorption of the hematoma occurred within an average of 3.8 days, significantly shortened in comparison with the 24 days in the medication group. The short-term (1 month) follow-up of the patients showed good neurological recovery in 58% of the patients in the minimally invasive group, significantly greater than the rate of 29% in the medication group; 6 months after the treatment, good neurological recovery was achieved in 50% of the patients in the minimally invasive group, but only 16% in the medication. No death occurred in the minimally invasive group, and 2 patients died in the medication group. The cost of hospitalization averaged 5136.3 Yuan in the minimally invasive group and 11843.6 Yuan in the medication group.

CONCLUSIONCompared with conservative treatment, the minimally invasive treatment with soft tube placement can significantly shorten the hospital stay, promote neurological function recovery, lower the mortality rate, and reduce the cost of hospitalization.

OBJECTIVETo study the optimum acupuncture treatment program and the mechanism for treatment of cerebral infarction.

METHODSSixty-three cases were randomly divided into 9 groups. The four factors, times of manipulation, the retaining time of the needle, acupuncture instrument and acupoints,and their corresponding three levels were adopted respectively in treatment of each group. Then nerve function defect score and insulin resistance were observed before and after treatment.

RESULTSThe acupoints, the times of manipulation and the retaining time of the needle have significant effects on nerve function defect and insulin resistance (P < 0.01 or P < 0.05), and the acupuncture instrument has a significant effect on insulin resistance (P < 0.01). The choice of acupoints was the most important factor for acupuncture treatment of cerebral infarction.

CONCLUSIONAcupuncture for regulating The Governor Vessel with twice manipulations and retaining the needle for 60 min is optimum treatment program for cerebral infarction. The good regulating effect of acupuncture on insulin resistance is one of the mechanisms of achieving the therapeutic results.

OBJECTIVETo investigate the clinical characteristics and prognosis of patients with different subtypes of breast cancer: basaloid, HER-2 and luminal types, and try to find the evidence of individualized treatment for the patients.

METHODS1280 histologically and immunohistochemically proven patients with resectable breast cancer were treated, and the clinical data including characteristics, relapse and survival of the patients with different subtypes of breast cancer were analyzed retrospectively.

RESULTSOf the 1280 breast cancer patients, basaloid, HER-2 and luminal types accounted for 20.9%, 23.2% and 55.9%, respectively. Basaloid type was more likely to be found in younger patients frequently with a family history of breast cancer. HER-2 type usually had a tumor of larger size with more advanced stage disease and more metastatic lymph nodes. Luminal type was likely to occur in aged patients with an earlier stage disease. The recurrence rates in basaloid, HER-2 and luminal types were 25.0%, 27.9% and 11.7%, respectively. Patients with basaloid or HER-2 type were found to have a significantly higher recurrence rate than the patients with luminal type breast cancer (P < 0.001), but no significant difference was observed between the basaloid and HER-2 types. However, patients with basaloid type breast cancer were more likely to develop lung metastasis than HER-2 type (13.4% vs. 7.1%, P = 0.017). Up to December 2006, the 5-year disease-free survival (DFS) rates for patients with basaloid, HER-2 and luminal types were 72.2%, 68.2% and 86.2% (P < 0.001), respectively. The overall 5-yr survival (OS) rates of the three groups were 88.6%, 83.8% and 95.8% (P < 0.001) , respectively. Of the patients with luminal type breast cancer, HER2-negative patients had a higher DFS (86.2% vs 57.0%, P < 0.001) and OS (95.8% vs 87.7%, P = 0.0001) compared with those with HER2-positive. The results of Multivariate Cox Regression showed that tumor size and lymph node state were the most important factors influencing the prognosis.

CONCLUSIONEach subtype of breast cancer has somewhat its own specific clinical features in terms of recurrence pattern and prognosis, therefore, individualized treatment regimen may be required.

OBJECTIVEYersinia enterocolitica is an extracellular pathogen and its related antigens interact with the host immune system. We investigated the difference in immunological characteristics between a highly pathogenic and poorly pathogenic strain of Y. enterocolitica.

METHODSWe used SDS-PAGE and western blotting to characterize lipopolysaccharide (LPS), Yersinia outer membrane proteins (Yops), membrane proteins, and whole-cell proteins from poorly pathogenic Y. enterocolitica bio-serotype 2/O:9, isolated from China, and highly pathogenic bio-serotype 1B/O:8, isolated from Japan.

RESULTSThese two strains of Y. enterocolitica had different LPS immune response patterns. Comparison of their Yops also showed differences that could have accounted for their differences in pathogenicity. The membrane and whole-cell proteins of both strains were similar; immunoblottting showed that the 35 kD and perhaps the 10 kD proteins were immunogens in both strains.

CONCLUSIONThe major antigens of the two strains eliciting the host immune response were the LPS and membrane proteins, as shown by comparing protein samples with reference and purified preparations.

Objective: To analyze the safety and efficacy of combined left atrial appendage (LAA) and patent foramen ovale (PFO) closure in adult atrial fibrillation (AF) patients complicating with PFO. Methods: This study is a retrospective and cross-sectional study. Seven patients with AF complicated with PFO diagnosed by transesophageal echocardiography (TEE) in Zhoupu Hospital Affiliated to Shanghai University of Medicine & Health Sciences from June 2017 to October 2020 were selected. Basic data such as age, gender and medical history were collected. The atrial septal defect or PFO occluder and LAA occluder were selected according to the size of PFO, the ostia width and depth of LAA. Four patients underwent left atrial appendage closure(LAAC) and PFO closure at the same time. PFO closure was performed during a one-stop procedure of cryoablation combined with LAAC in 2 patients. One patient underwent PFO closure at 10 weeks after one-stop procedure because of recurrent transient ischemic attack (TIA). All patients continued to take oral anticoagulants. TEE was repeated 8-12 weeks after intervention. In case of device related thrombus(DRT), TEE shall be rechecked 6 months after adjusting anticoagulant and antiplatelet drug treatment. Patients were follow-up at 1, 3, 6, 12, 24 months by telephone call, and the occurrence of cardio-cerebrovascular events was recorded. Results: Among the 7 patients with AF, 2 were male, aged (68.0±9.4) years, and 3 had a history of recurrent cerebral infarction and TIA. Average PFO diameter was (3.5±0.8)mm. Three patients were implanted with Watchman LAA occluder (30, 30, 33 mm) and atrial septal defect occluder (8, 9, 16 mm). 2 patients were implanted with LAmbre LAA occluder (34/38, 18/32 mm) and PFO occluder (PF1825, PF2525). 2 patients were implanted with LACbes LAA occluder (24, 28 mm) and PFO occluder (PF2525, PF1825) respectively. The patients were followed up for 12 (11, 24) months after operation. TEE reexamination showed that the position of LAA occluder and atrial septal defect occluder or PFO occluder was normal in all patients. DRT was detected in 1 patient, and anticoagulant therapy was adjusted in this patient. 6 months later, TEE showed that DRT disappeared. No cardiovascular and cerebrovascular events occurred in all patients with AF during follow-up. Conclusions: In AF patients complicated with PFO, LAAC combined with PFO closure may have good safety and effectiveness.

Herpes simplex virus type 1 (HSV-1) is a ubiquitous and widespread human pathogen, which gives rise to a range of diseases, including cold sores, corneal blindness, and encephalitis. Currently, the use of nucleoside analogs, such as acyclovir and penciclovir, in treating HSV-1 infection often presents limitation due to their side effects and low efficacy for drug-resistance strains. Therefore, new anti-herpetic drugs and strategies should be urgently developed. Here, we reported that baicalein, a naturally derived compound widely used in Asian countries, strongly inhibited HSV-1 replication in several models. Baicalein was effective against the replication of both HSV-1/F and HSV-1/Blue (an acyclovir-resistant strain)
