[Summary]_ Severe hypertriglyceridemia is the third common cause of acute pancreatitis following after alcohol abuse and cholelithiasis. Moreover, it is also an important risk factor of cardiovascular events. However, the cases of severe hypertriglyceridemia caused by autoimmune disease were rare in clinical, which would bring the difficulty for diagnosis and treatment. A better understanding of the clinical characteristics, possible pathogenesis, and corresponding therapy of the disease would be helpful, which would reduce the risk of complications, and finally improve both the survival rate as well as quality of life of these patients.

OBJECTIVE To clarify the long-term toxicity to the respiratory system in a rat model of acute lung injury (ALI) induced by a single low-dose of perfluoroisobutylene(PFIB) inhalation expo?sure,and observe the possible beneficial effect of early intervention via Qingkailing(QKL) injection. METHODS Totally 224 male Wistar rats were randomly divided into 4 groups:normal control group in which air exposure was followed by a saline 10 mL · kg-1(ip),QKL control group in which QKL 10 mL · kg-1 was ip given after air exposure,PFIB exposure group in which rats were exposed to PFIB 280 mg·m-3 for 5 min only,and QKL treatment group in which QKL 10 mL·kg-1 was given ip at 1 h after PFIB exposure. Lung functions of rats were measured at 24 h,3,6,12,24,36 and 48 weeks after exposure. The arterial blood gas,lung coefficient,protein content in bronchoalveolar lavage fluid(BALF),hydroxy?proline(HYP) content in lung tissue and plasma,and other indicators were detected or analyzed. RESULTS Within 24 h after PFIB exposure,the lung coefficient and protein content in BALF were increased significantly(P<0.01),whereas the PaO2(P<0.01) and SaO2(P<0.05) indices in arterial blood decreased significantly in PFIB group compared with normal control. The inhalation time , exhalation time,tidal volume(TV),expired volume(EV)and relaxed time were reduced significantly (P<0.01). However,all the above indicators returned to normal in 3 weeks,but TV,EV and peak expiratory flow were significantly lower than in normal group at 48 weeks(P<0.05). HYP contents in lung tissues,compared with normal control(P<0.05),were reduced significantly within 24 h after PFIB exposure,increased significantly in 6 weeks(P<0.05),then returned to normal in 12 weeks. HYP contents in plasma increased significantly compared with normal control(P<0.05) within 24 h after PFIB exposure but returned to normal in 3 weeks. The protein contents in BALF of QKL treatment group were significantly lower than those in PFIB group(P<0.01) within 24 h after PFIB exposure. From 24 h to 24 weeks after PFIB exposure,changes of pulmonary functions were similar to those in PFIB group. At 48 weeks,TV and EV in QKL treatment group were more significantly increased than those in PFIB group(P<0.05). CONCLUSION Rats with ALI induced by a single low dose of PFIB exposure undergo compensatory repair except for pulmonary capacity and pulmonary ventilation functions. Early treatment with QKL reduces protein content of BALF and alleviates pulmonary edema,and has some beneficial effect on lung function recovery later.

6.Progress in treatment of lymphoma-associated hemophagocytic syndrome
Journal of Leukemia & Lymphoma 2022;31(9):571-573
Lymphoma-associated hemophagocytic syndrome (LAHS) accounts for a large proportion of secondary hemophagocytic syndrome (HPS) and has a poor prognosis. LAHS can be divided into two categories: HPS combined with chemotherapy and lymphoma-induced HPS. The key to the treatment of HPS combined with chemotherapy is to control the infection. While the treatment of lymphoma-induced HPS is complicated, there are new strategies in addition to traditional methods. Timely and appropriate treatment can significantly improve the short-term and long-term prognosis of patients. This article summarizes the progress in treatment of LAHS.

OBJECTIVETo investigate the effect of polyethylene oxide (PEO) on renal blood flow and its renoprotective effect in rabbits with endotoxin sepsis.
METHODSTwenty normal New Zealand white rabbits were randomly divided into normal saline (NS) group and PEO group (n=10), and endotoxin shock was induced by an intravenous injection of 0.6 mg/kg lipopolysaccharide. Resuscitation was performed when the blood pressure of the rabbits showed a 30% decline, using NS (in NS group) or the mixture of equal volumes of NS and 20 ng/g PEO (in PEO group) perfused at the rate of 5 ml/kg per hour. Before and during shock and at 1 h after resuscitation, the renal hemodynamics was monitored by ultrasound and the venous blood was extracted to examine the renal functions. The heart rate and arterial blood pressure were monitored throughout the experiment.
RESULTSThe rabbits in both groups showed a significantly lower renal artery blood flow velocity during the shock (P<0.05) with significantly increased pulsatility index (PI) and resistance index (RI) compared with those before the shock. One hour after resuscitation, the blood flow velocity in the renal arteries at all levels and the tertiary veins were reduced in NS group without obvious reduction of the PI and RI; in PEO group, the blood flow velocities in the renal arteries increased significantly compared to those before shock (P<0.05), and the PI and RI of the tertiary arteries were significantly lower than those in NS group (P<0.05). In both groups, BUN and Cr increased during endotoxin shock stage, and 1 h after resuscitation, PEO group showed significantly lower BUN and Cr levels than NS group (P<0.05).
CONCLUSIONA small dose of PEO can significantly promote renal perfusion in rabbits with septic shock, thus offering renoprotective effect against early damage in septicopyemia and septic shock.
