1.Investigation progress of proprotein convertase subtilisin/kexin type 9 influencing the metabolism of cholesterol
Basic & Clinical Medicine 2006;0(06):-
Familial hypercholesterolemia(FH) is a common autosomal dominant dyslipidemia,which is caused by mutations of the low-density lipoprotein receptor(LDLR) gene producing defect or deficiency in LDLR.The characters of FH are elevated level of total and LDL cholesterol.FH is considered to be a complex polygenic disease.Recently,more findings indicate that proprotein convertase subtilisin/kexin type 9(PCSK9) gene play an important role in serum cholesterol metabolism.Some mutated PCSK9 proteins decrease LDLR,which cause FH in affected families.Some other mutated PCSK9 proteins decrease self-affinity,which cause hypocholesterolemia.We review the newest researches about the structure,function ofPCSK9 gene and the relation of its mutations with plasma cholesterol metabolism.

AIM: To explore the mutual effect of co-culture of wild-type astrocytes (ASC) and motor neurons VSC4.1 (VSC) on the respective ability to produce reactive oxygen species (ROS). METHODS: The inhibition rates of cell growth in ASC and VSC in co-culture or independent culture was detected after exposed to excitatory stimulus by MTT method. Real-time observation of ROS production by ASC and VSC labeled with Hoechst 33342 was detected by confocal microscopy under the conditions of co-culture or independent culture. RESULTS: Higher concentration of glutamate induced a higher inhibition rate in mixed cell growth than that in ASC alone, while lower concentration of glutamate induced a higher inhibition rate in mixed cell growth than that in VSC only. Real-time observation by confocal microscopy showed that ROS production by VSC under the condition of co-culture, which showed a notable increase at 15 min, was significant less than that in independent culture, which peaked at 5 min and was gradually decreased. ROS production by ASC in co-culture began to increase significantly at 10 min. CONCLUSION: Compared to independent culture, ASC reduces the resting ROS production by co-cultured with VSC, while ASC prolongs the duration of ROS production by VSC after exposed to excitatory stimulus.

OBJECTIVETo recommend an improved method of prostate massage, which is safe, effective, simple and tolerable, and may increase the expressed prostatic secretin (EPS) success rate and promote the efficiency of the prostate massage.
METHODSTwo methods are described in this paper, one being the aside-bending and up-standing vs parallel and semi-squatting method to massage the prostate via the rectum, and the other being the traditional massage method. A total of 261 chronic prostatitis (CP) patients were randomly divided into two groups, and treated separately with the new method and the traditional method. Then, the two methods were compared by EPS quantity and the patients' tolerability.
RESULTSThe new method made it possible to collect larger quantity of EPS. The results of comparison showed that the new method was better received by the patients.
CONCLUSIONThe aside-bending and up-standing vs parallel and semi-squatting method to massage the prostate via the rectum may increase the EPS success rate of prostatic massage and hence help the clinical diagnosis and treatment of chronic prostatitis. This method is well worth recommending.

OBJECTIVETo report on a novel human leukocyte antigen (HLA) allele.
METHODSPolymerase chain reaction-sequence based typing was used for routine HLA typing. For one sample, the result of B locus typing showed mismatch of one base with B*46:01:01, B*15:25:01 at locus 384. The group specific sequencing primers, which target at B*46 and B*15, were used to confirm the difference between the novel allele and the highest homologous allele.
RESULTSThe sequencing results showed that the highest homologous allele to the novel allele was B*46:01:01. The two sequences only differed for position 384 within the exon 3 (384G>T), which resulted in a codon change (GGG>GGT), though the amino acid sequence of the novel allele at position 104 was still Glycine (G). Investigation of the family showed that the novel allele was inherited from the father.
CONCLUSIONThe novel HLA-B allele, discovered in ethnic Zhuangs from Guangxi, has been designated as HLA-B *46:01:18 by the World Health Organization (WHO) HLA Nomenclature Committee.

Objective:To evaluate the treatment of infected nonunion after internal fixation of subtrochanteric fracture with a reconstruction stent of external fixation.Methods:A retrospective study was conducted to analyze the data of 5 male patients with infected nonunion after internal fixation of subtrochanteric fracture who had been treated and completely followed up at The Great Wall Orthopaedics and Hand Surgery Hospital from January 2017 to October 2022. The patients were (30.0±13.5) years old. Seinsheimer fracture types: ⅢA (1 case), ⅢB (1 case), Ⅳ (2 cases), and Ⅴ (1 case); original internal fixation: intramedullary system (4 cases) and plate fixation (1 case); the Cierny-Mader anatomical classification: type Ⅳ (diffuse type) for all. After complete debridement at stage one, 2 or 3 hydroxyapatite (HA) coated screws were placed at both fracture ends from the lateral side of the femur for unilateral reconstruction external fixation. Next, a hybrid external fixation scaffold was added with a 1/3 ring at the sagittal position and 1 or 2 HA screws in 4 cases while unilateral reconstruction external fixation was constructed at both sides by inserting 2 HA screws into both fracture ends from the anterior femur at the sagittal position in 1 case. Antibiotic bone cement was used to fill bone defects of (3.8±1.8) cm. At 6 to 8 weeks after debridement when infection did not recur, antibiotic bone cement was removed before autogenous iliac bone grafting was performed in 3 patients and osteotomy bone transport in 2 patients. Infection control, bone union time, time for removal of external fixation stent, complications, Sanders hip function score and Paley bone outcome score were recorded.Results:The 5 patients were followed up for (23.4±8.1) months after surgery. Infection at the fracture ends was controlled after 1 time of debridement in 3 patients and after 2 times of debridement in 2 patients. The loosening HA screws were replaced twice due to infection at the proximal nail tract, and autologous bone grafting was performed at the opposite fracture ends in 1 case; no complications occurred in the other 4 cases. Bony union was achieved at the extended segment and fracture ends in all patients. The time for imaging union after bone reconstruction was (10.2±3.4) months. The time for wearing a stent of external fixation was (18.0±4.5) months. There was no recurrent infection or lingering infection. According to the Sanders hip function score at the last follow-up, 4 cases were excellent and 1 case was good; according to the Paley bone outcome score, the curative effect was excellent in all.Conclusion:Application of a reconstruction stent of external fixation combined with antibiotic bone cement can control infection at the first stage and conduct bone reconstruction at the second stage to successfully treat the infected nonunion and preserve the hip function after internal fixation of subtrochanteric fracture.

ObjectiveTo explore the difference of learning and memory function between permanent cerebral ischemia and ischemia-reperfusion rat models by filament-occluded method after three weeks of natural recovery, and to observe the changes of brain structure. MethodsA total of 21 SPF male Sprague-Dawley rats were randomly divided into sham group (n = 7), permanent ischemia group (n = 7) and ischemia-reperfusion group (n = 7). The latter two group underwent left middle cerebral artery occlusion, and the ischemia-reperfusion group was reperfused after 90 minutes of ischemia. All the rats were tested with Morris Water Maze 16 to 22 days after modeling, to record escape latency in the navigation experiment, as well as first latency, platform quadrant swimming time ratio and distance ratio, boundary swimming time ratio and distance ratio, average speed, and the swimming path in the space exploration experiment. On the 22nd day after modeling, four rats with similar Longa scores in each group were scanned by magnetic resonance by diffusion tensor imaging, to measure the fractional anisotropy (FA) of cerebral ischemic cortex, striatum, hippocampus and their corresponding contralateral regions, to calculate ratio of FA (rFA); as well as the volume of infarct (VI) and ratio of VI (rVI). ResultsFor navigation experiment, the escape latency decreased in all the groups with the time (F = 36.202, P < 0.001), but it was not significant for the permanent ischemia group (F = 4.004, P > 0.05). The escape latency was longer in the permanent ischemia group than in the other two groups at each time points (P < 0.05). For space exploration experiment, the boundary time ratio and distance ratio were more in the permanent ischemia group and the ischemia-reperfusion group than in the sham group (P < 0.017), and the first latency was longer in the permanent ischemia group than in the sham group (P < 0.017). The swimming path of ischemia-reperfusion group and sham operation group was better than that of the permanent ischemia group. FA and rFA in left cortex and striatum were less in the permanent ischemia group and the ischemia-reperfusion group than in the sham group (P < 0.05), while FA and rFA of left cortex and FA of left striatum were less in the permanent ischemia group than in the ischemia-reperfusion group (P < 0.05). The VI and rVI were larger in the permanent ischemia group than in the ischemia-reperfusion group (t > 4.185, P < 0.01). FA and rFA of left cortex and striatum correlated with escape latency, boundary time ratio and distance ratio (|r| > 0.498, P < 0.05). The VI and rVI correlated with escape latency and boundary time ratio (|r| > 0.538, P < 0.05). ConclusionCognitive impairment is more severe in the rat model of permanent cerebral ischemia, which may relate to the larger damage of structure of nerve fibers in ischemic cortex and striatum, and larger infarct size.
