Objective To detect genetic mutation of apolipoprotein B-100(apoB-100)in patients with primary hypercholesterolemia.Methods One special segment of apoB-100 gene from nucleotide 10549 to 10895 was amplified by polymerase chain reaction(PCR).The PCR products were denatured and hybridized with specific aligonucleotide labeled with digoxigenin,and were analyzed by single strand conformation polymorphism(SSCP)to detect the apoB-100 gene mutation 3531CGC→CGT or other mutations.Results Overall 41 members of 11 primary hypercholesterolemia families were detected,but the above genetic mutation was not detected.Conclusion This genetic mutation is unlikely to exist or of significantly low incidence in Chinese population,and might not be the main cause of primary hypercholesterolemia in the 11 primary hypercholesterolemia families.

OBJECTIVE: To discuss the clinical characteristic and surgical treatment of nasal sinus osteoma. METHOD: Fifty-one cases with nasal sinus osteoma were diagnosed by nasal sinus X ray or CT scan. All of these osteoma patients were cured by surgical resection. Supraorbital Lynch approach were applied in forty-two cases, lateral rhinotomy Moure approach in 4 cases, Caldwell-Luc approach in 3 cases and Dandy approach that combined with cranium and facial route in 2 cases. RESULT: Operative incisions in all cases healed in 1 period, no complications such as brain spinal fistula occurred. All cases were followed up for 6 months to 5 years, there were no recurrence of osteomas and occurrence of mucus cysts. CONCLUSION Osteomas in nasal sinus grow slowly. X ray or CT scan is helpful to confirm the diagnosis and choose the surgical approach reasonably.

OBJECTIVETo evaluate the combinated transcatheter hepatic artery chemoembolization (TACE) and analyse the factors affecting prognosis in patients with primary hepatic carcinoma.

METHODS141 consecutive patients with primary hepatic carcinoma were treated, including 125 men and 16 women (mean age, 52 years; age range, 21 - 76 years). Combinated TACE procedures included TACE, TACE followed by surgical resection, TACE and percutaneous ethanol injection (PEI) and transcatheter hepatic artery infusion (TAI). The factors included sex, age, ALT, AFP, HBsAg, liver function (Child's system), the way of treatment, tumor size and number, serum albumin, portal cancerous thrombus, pathological type of tumors, and HBeAg. The Cox's regression analysis model was used to analyse the factors affecting the prognosis. P < 0.05 means statistically significant difference.

RESULTSThe total median survival time was 19 months and mean survival time 23.59 months. The total survival rates of 1, 2, 3, 5 years were 63.9%, 44.5%, 25.8% and 7.4%, respectively. Multivariable analysis revealed significant prognostic factors as follows: age, liver function, the way of treatment, portal cancerous thrombus and pathological types of tumors (chi2 = 45.993, P = 0.0001).

CONCLUSIONThe combinated TACE procedure is safe and effective. In this study, 5 factors directly influencing the prognosis are age, liver function, portal cancerous thrombus and pathological types of tumors are risk prognostic factors, and the way of treatment is a protective factor (chi2 = 45.993, chi2 = 0.0001).

OBJECTIVETo investigate a new operation of breast reduction for gynecomastia.

METHODSIn the past 5 years we treated 42 cases (80 sites) of gynecomastia with the double-ring incision, a supra-lateral derma-mammary pedicle of the nipple and areola and the tumescent technique.

RESULTSThe tumescent anesthesia was effective. The operation was easily performed with slight injury and less bleeding. It was safe and the patients recovered quickly. 100 to 500 grams tissue was resected from one breast. There have been no severe postoperative complications, such as nipple or areola necrosis. Follow-up from 3 to 48 months showed satisfactory results except that there was mild scar hypertrophy on the incision around the areola.

CONCLUSIONSThe new operation for gynecomastia with the double-ring incision, a supra-lateral derma-mammary pedicle of the nipple and areola, and the tumescent anesthesia is a good, reliable and convenient technique.

Objective: To discuss the application of Mohs microsurgery in nasal and facial basal cell carcinoma (BCC) and analyze the pathological and clinical features. Methods: The clinical data of 127 patients who were diagnosed by pathology as nasal and facial BCC in Qilu Hospital of Shandong University from January 2010 to January 2015 were retrospectively analysed. The value of Mohs microsurgery was discussed and the nasal & facial sites of BCC lesions, clinical and histopathology features were summarized. Results: The proportion of male and female was 1.27︰1 in 127 patients, the ages ranged from 27 to 91 years. The top three inflicted area in nasal and facial was followed by nasal dorsum, nasal root and upper lip.The most frequent clinical type was nodular ulcerative type.The most common pathological type was nodular and pigmented. Routine surgical resection was performed in 62 cases (48.8%) while Mohs micrographic surgery in 38 cases (29.9%). Follow-up duration was 37 months on average. Local recurrence occurred in 5 cases in routine surgical resection group while there was no recurrence in Mohs micrographic surgery group. There was no distant metastasis in all cases. Conclusions There are few specific clinical manifestation in nasal & facial BCC. Surgical treatment is prefered, especially by Mohs micrographic surgery, because it can strictly control the scope of surgical resection and obtain malformation repairment as well as beauty in nasal and facial region.

Fish bile poisoning may damage human liver and kidney, causing degeneration and necrosis. Can also damage brain cells and heart muscle, resulting in nervous system and cardiovascular system lesions. This paper reports a case of a patient who developed multiple organ dysfunction syndrome (MODS) after oral administration of fish bile with Xiexin folk prescription for eye disease. In January 2020, he went to the poisoning and occupational diseases department of the emergency department of Qilu hospital. After receiving hemoperfusion, continuous renal replacement therapy (CRRT) and symptomatic support treatment, the patient was improved and discharged. CRRT combined with HP is one of the rapid and effective methods for the treatment of acute fish bile poisoning.

Objective To investigate the effects of gender and age on the prevalence and complications of nonalcoholic fatty liver disease(NAFLD). Methods A total of 8429 NAFLD patients were selected from the Health Check-up Center and Outpatient Departments of Qilu Hospital of Shandong University(Qingdao).The questionnaire-based survey,physical examinations,biochemical tests,and liver ultrasonography were performed for all cases.Patients were divided into young group(<45 years),middle aged group(45 years≤age<60 years),and old group(≥60 years)according to age,and the clinical features and laboratory findings were analyzed. Results The proportion of male patients gradually decreased with age,while the proportion of female patients increased(P<0.01);The incidences of metabolic diseases showed significant difference among young group,middle aged group,and old group(P<0.01).Except for hyperlipidemia,the proportion of male patients with NAFLD-accompanied metabolic symdrome was significantly higher than that of female patients in all three age groups(all P<0.01). Conclusions The prevalence of NAFLD-accompanied metabolic syndrome disease is associated with age and gender.This finding is useful for the prevention and treatment of NAFLD.

OBJECTIVETo culture and amplify the young rabbit's bone marrow stromal cells (BMSCs) in vitro, and to observe the effect of hypothermia on the cells' growing behavior and biological function.

METHODSBMSCs were acquired from the rabbit' tibia bone marrow and induced to mature osteoblasts in vitro. The cultured cells growing well in vitro were preserved in liquid nitrogen. The anabiotic cells having cryopreserved for 1 week were chosen as the experimental group, and the routine 7th generation as the control group. Their biological function in comparion by the examination of morphological changes, cells' proliferation ability, colone forming ratio, synthesis ability of ALP and protein, mineralized nodes forming ability were observed.

RESULTSAs contrast to the control groups, the anabiotic cells also grew and proliferated well in vitro except a little more slowly than before. They had the similar general shape in all the time segments, but a little differences in cells' ultrastructure. The experimental groups also had the typical characters of mature osteoblasts, and high abilities of the synthesis of ALP and proteins. The statistic data showed that these two groups had no significant difference (P > 0.05).

CONCLUSIONThe cryopreserved osteoblasts had the same biological functions and the similar growing behaviors as before. These results suggest that it is practical to use the cryopreserved osteoblasts for further study on bone tissue engineering.

OBJECTIVETo investigate the effects on the phenotype, especially the mineralization ability of human embryonic lung fibroblasts(HELFs) by transfection with adenovirus vector ecoding human bone morphogenetic protein-2 gene (Ad-BMP-2).

METHODSThe HELFs were primarily cultured, then transfected with Ad-BMP-2. The morphologic characteristics of the cells were observed. The cell proliferation, alkaline phosphatase activities, BMP-2 protein expression, and the mineralization ability were detected with the methods of MTT, ALP staining, Western blot, and alizarin red S staining, respectively.

RESULTSAfter transfection, the shape of HELFs changed from silm spindle to multifigure, the cells became bigger than before. The colonies changed from unilaminar into multilaminar. The proliferation of HELFs was severely inhibited after transfection. An obvious BMP-2 lane was shown in Western blotting. Most cells presented positive in ALP staining, and large number of nacarat mineralized nodes were observed after alizarin red S staining.

CONCLUSIONHELFs were capable of transforming into osteoblast-like phenotype, and were endowed with the ability of mineralization while being transfected with Ad-BMP-2.
