BACKGROUND: Peri-intraventricular hemorrhage (PIVH) in preterm infants is one of the most important reasons for mortality and disability. Moreover, investigative exponents may bring supported data for incidence rate of PIVH and high-risk factors of preterm infants with PIVH.OBJECTIVE: To explore the incidence rate and analyze the high-risk factors of PIVH in preterm infants.DESIGN: Survey and analysis.SETTING: Tongji Hospital of Tongji Medical College, Huazhong University of Science and Technology; Beijing Obstetrics & Gynecology Hospital, Capital Medical Universit; Qinhuangdao Maternity and Infants' Hospital of Hebei Province.PARTICIPANTS: A total of 1 122 preterm infants of 26.3-36.8 gestational age were selected from Beijing Obstetrics & Gynecology Hospital, Qinhuangdao Maternity and Infants' Hospital from January 2002 to August 2005. All infants received ultrasonic examination on skull within 1 week. There were 594 boys and 528 girls, and the birth weight was 850-4 500 g.METHODS: All infants received ultrasonic examination on skull within 1 week. New Philips 5500 and GE Healthcare Logiq 400 ultrasonic diagnosis devices were provided by Philip Company, Dutch and GE Company, respectively.MAIN OUTCOME MEASURES: The incidence rate and related high-risk factors of PIVH.RESULTS: All 1 122 preterm infants were involved in the final analysis. Among 1 122 preterm infants, 619 cases (55.2%) had PIVH; especially, 110 had severe PIVH with the degree more than Ⅲ, which was accounted for 17.8%.High-risk factors were mainly low gestational age, low birth weight, mechanical ventilation, hypoglycemia, hypercapnia,hyperlactic acidemia, acidosis, hypoxia, abnormal blood coagulation, and so on. Antenatal corticosteroid could reduce the incidence rate of PIVH. However, there was no obvious effect on preterm infants of old gestational age.CONCLUSION: Routine intracranial ultrasonic examination is useful for the diagnosis of PIVH in preterm infants.

Objective:To evaluate the preoperative localization value of endoscopic ultrasound guided fine needle tattooing (EUS-FNT) for laparoscopic distal pancreatectomy in pancreatic lesions with a maximum diameter ≤3 cm.Methods:From November 2017 to October 2022, at the Second Affiliated Hospital of Soochow University, the data of patients with pancreatic lesions ≤3 cm who underwent laparoscopic distal pancreatectomy were retrospectively analyzed. Eight patients who underwent EUS-FNT assisted laparoscopic distal pancreatectomy were included in the fine needle tattooing (FNT) combined laparoscopic group. And 14 patients who underwent simple laparoscopic distal pancreatectomy were taken as the simple laparoscopic group. The success rate and complications of EUS-FNT were observed. The differences in operation time, surgery-related complications and complete resection rate of lesions between the two groups were compared. Mann-Whitney U test and descriptive analysis were used for statistical analysis. Results:In the FNT combined laparoscopic group, the lesions of 4 cases were located in the pancreatic body and 4 cases in the pancreatic tail. In the simple laparoscopic group, the lesions of 4 cases were located in the pancreatic body and 10 cases in the pancreatic tail. There was a significant difference in lesion size between the two groups (14.5 mm (10.8 mm, 16.5 mm) vs. 27.0 mm (23.5 mm, 30.0 mm), Z=-3.09, P=0.001). In the FNT combined laparoscopic group, EUS-FNT was successfully performed in all 8 patients. The average time of laparoscopy after EUS-FNT was (98.4±8.8) min. The marks were clearly visible under the laparoscopic field of view, and no complications such as abdominal hemorrhage and hematoma were observed. Laparoscopic pancreaticocaudectomy was performed in 5 cases and pancreaticocaudectomy plus splenectomy in 3 cases. The median operation time was 192.5 min (176.3 min, 203.8 min). The amount of intraoperative bleeding was large in 2 patients and blood transfusion was needed. The lesions were one-time completely resected in all 8 patients. The postoperative pathology were 6 cases of pancreatic neuroendocrine neoplasm, 1 case of intraductal papillary mucinous neoplasm (IPMN), and 1 case of solid pseudopapilloma. In the simple laparoscopic group, laparoscopic pancreaticocaudectomy was performed in 2 cases and pancreaticocaudectomy plus splenectomy in 12 cases. The median operation time was 202.5 min (192.8 min, 235.0 min), which was longer than that of FNT combined laparoscopic group, but the difference was not statistically significant ( P>0.05). The amount of intraoperative bleeding was large in 2 patients and blood transfusion was needed. In 1 patient with pancreatic body lesions, no lesion was found in the specimen examination after the first pancreatectomy, and the lesions were completely resected after the second partial pancreatectomy. Active abdominal hemorrhage occurred in 1 patient on the second day after operation, and underwent interventional embolization for hemostasis. Two weeks after surgery, 1 patient was found to have a encapsulated fluid with a long diameter of 6 cm around the pancreas by computed tomography re-examination 2 weeks after surgery. The postoperative pathology were 5 cases of pancreatic neuroendocrine neoplasm, 2 cases of IPMN, 1 case of solid pseudopapilloma, 1 case of pancreatic cyst with glandular low-grade intraepithelial neoplasia, 1 case of ectopic spleen, and 4 cases of pancreatic ductal adenocarcinoma. Conclusion:EUS-FNT can effectively localize small pancreatic lesions before laparoscopic distal pancreatectomy, shorten the operation time and improve the complete resection rate under laparoscopy.

OBJECTIVE:
To study the protective effect of enhanced peroxisome proliferator activated receptor γ (PPARγ) pathway against apoptosis of long-term cultured primary nerve cells.
METHODS:
A natural aging model was established in primary rat nerve cells by long-term culture for 22 days. The cells were divided into control group, 0.1, 1.0, 5.0, and 10 μmol/L GW9662 intervention groups, and 0.1, 1.0, 5.0, and 10 μmol/L pioglitazone intervention groups. The cell viability was assessed using MTT assay and the cell morphological changes were observed after the treatments to determine the optimal concentrations of GW9662 and pioglitazone. Double immunofluorescence labeling and flow cytometry were used to observe the changes in the number of viable cells and cell apoptosis following the treatments; immunocytochemical staining was used to assess the changes in the anti-oxidation ability of the treated cells.
RESULTS:
The optimal concentrations of GW9662 and pioglitazone determined based on the cell viability and morphological changes were both 1 μmol/L. Compared with the control group, GW9662 treatment significantly lowered while pioglitazone significantly increased the total cell number and nerve cell counts ( < 0.05), and nerve cells in the cell cultures maintained a constant ratio at about 80% in all the groups ( > 0.05). GW9662 significantly enhanced while pioglitazone significantly lowered the cell apoptosis rates compared with the control group ( < 0.05). GW9662 obviously lowered SOD activity and GSH content in G group ( < 0.05) and increased MDA content in the cells ( < 0.05), and pioglitazone resulted in reverse changes in SOD, GSH and MDA contents in the cells ( < 0.05).
CONCLUSIONS
Activation of PPARγ pathway protects long-term cultured primary nerve cells by enhancing cellular anti-oxidant capacity and reducing cell apoptosis, suggesting a potential strategy for anti-aging treatment of the nervous system through intervention of the PPARγ pathway.
