Objective:To investigate the diagnosis, treatment and aeromedical assessment of military flying personnel with cerebral cavernous malformations (CCM).Methods:The clinical data and aeromedical assessment conclusions of military flying personnel with CCM in Air Force Medical Center from 2015 to 2021 were collected and analyzed based on reviewing the relevant aeromedical assessment cases and literatures at home and abroad.Results:A total of 10 flying personnel, all male, 20-41 years old, with an average age of 28.3 years, including 8 pilots, 2 air combat/technical personnel, with the flying hours of 110-4 000 h and the average flying hours of 1 102.0 h. The sizes of lesions were 3-12 mm, including 2 cases were smaller than 5 mm, 6 cases were 5-10 mm and 2 cases were bigger than 10 mm. All lesions were located under the cortex, including a case of occipital lobe, 4 cases of frontal lobe, 2 cases of temporal lobe and 3 cases of cerebellar hemisphere. Among the 10 flying personnel, only a case presented intracranial haemorrhage (right cerebellar hemisphere) as first symptom and was treated surgically. Three cases were temporarily grounded due to they were under the grounding observation. Other 7 flying personnel had been followed up for more than 6 months. Their reexaminations of MRI showed no change in lesions and EEG examination showed no abnormalities. Two air combat/technical personnel were qualified for flight and 1 helicopter pilot was limited to be a co-pilot, and 2 dual-seat fighter pilots were qualified (limited to dual-seat fighter) and flight-qualified respectively. Two fighter pilots were qualified for lower performance aircraft (limited to bomber, transporter or helicopter).Conclusions:For CCM military flying personnel, the aeromedical assessment conclusion should be made according to the symptoms, lesion location and size, inflight incapacitation possibility assessment, treatment effect, ground observation and follow-up results, as well as the aircraft type and occupation.

Objective To observe the effects of telmisartan treatment on the abdominal fat deposit in metabolic syndrome (MS) combined with essential hypertension (EH).Methods Sixty patients of MS combined with EH were divided into two groups according to random number table method,with 30 cases in each group.The patients in experimental group were given telmisartan orally 40 mg once a day,and in control group were given valsartan 80 mg once a day,until average ambulatory blood pressure monitoring blood pressure was ＜ 140/90 mmHg (1 mmHg =0.133 kPa) in 24 weeks.The visceral fat area (VFA) and subdermal fat area (SFA) was measured by multislice CT,at the same time the body mass index (BMI),blood pressure,blood glucose,homeostasis model assessment of insulin resistance (HOMA-IR) and glyeosylated hemoglobin (HbA1c) of the subjects was measured.Results The blood pressure,BMI,blood glucose,HbA1c,and blood lipids between two groups before treatment had no statistical significance (P ＞0.05).VFA in experimental group after treatment was lower than that before treatment [(127.8 ± 16.6) cm2 vs.(150.5 ± 15.4) cm2] (P ＜ 0.05).But there was no statistical significance of VAF in control group before and after treatment (P ＞0.05).The SFA in experimental group and control group had no statistical significance before and after the treatment (P ＞ 0.05).The HOMA-IR in experimental group after treatment was reduced compared with that before treatment (1.9 ± 0.3 vs.4.2 ± 0.9),and adiponectin was increased [(5.77 ±0.71) mg/L vs.(3.16 ±0.72) mg/L] (P ＜0.05).Conclusion Compared with valsartan,telmisartan can significantly reduce the visceral fat deposition in MS combined with EH patients and improve insulin resistance.

Objective To discuss the clinical values of two-dimensional and three-dimensional diagnoses of nontraumatic esophageal hiatal hernia (HH) in middle-aged and elderly people. Methods Thirty-two cases underwent two-dimensional and three-dimensional ultrasonic examination with fasting and water iflling methods in half-sitting, standing, supine and supine right anterior oblique positions. The ifndings were compared with X-ray barium meal examination, endoscopy and operation. Results There were 27 cases sliding HH, 3 cases paraesophageal HH and 2 cases short HH. Traditional two-dimensional manifestations were as follows:widening of hiatal diaphragmatic muscles (1.6±0.4 cm) and echoes of gastric mucosa in superior hernial sac and inside hernial sac. Real-time three-dimensional surface image formations were as follows: along the long axis of diaphragmatic hiatus, superior phrenic sac was showed as mushroom-shaped or pond-shaped and the neck of hernial sac was showed as irregular tunnel-shaped or ditch-shaped;looking upward from the fundus of stomach, superior phrenic hiatus was showed as caved-shaped or louver-shaped;looking downward from mediastinal surface of lung, uperior phrenic hiatus was showed as piercer-shaped. Conclusions Two-dimensional abdominal ultrasound can diagnose nontraumatic HH in middle-aged and elderly people conveniently and accurately. Real-time three-dimensional abdominal ultrasound can display the range, size, and shape clearly. Compared with the former, the latter can provide more information for diagnosis and help ultrsound doctors and clinical doctors to understand and master the anatomical and morphopathological features of this disease.

Objective To observe the clinical therapeutic effects and evaluate the security of Huganjiexian decoction combined with conventional therapy on hepatic cirrhosis.MethodsBy the randomized and prospective study method,34 patients with liver cirrhosis were divided into experimental group and control group.The experimental group was treated with Huganjiexian decoction combined with conventional therapy while the control group was treated with conventional therapy alone.Patients in both groups were treated six months.At the beginning and 6 months after treatment,levels of alanine transaminase (ALT),aspartate transaminase (AST),albumin (ALB),albumin/globulin (A/G),total bilirubin (TBiL),blood urea nitrogen (BUN),serum creatinine (Scr) were determined.Results Levels ofALT、AST、TBiL decreased in both groups after being treated for six months,and the differences of downward trend of the experimental group were more significant than control group (F=36.63,40.31,38.65,P＜0.05).Levels ofALT、AST、TBiL of the experimental group were lower than those of control group significantly (F=8.67,7.62,4.36,P＜0.05 ).The A/G raised in both groups after treatment,and the upward trend of the experimental group was greatly different from that of control group (F=24.10,P＜0.05),the value of A/G of the experimental group was higher than that of control group (F=4.78,P＜0.05).The ALB raised in both groups after treatment,while the upward trend of the experimental group was no different from that of control group (F=0.89,P＞ 0.05).Thevalue of ALB had no significant changes in both groups (F=3.15,P＞0.05).Conclusion Huganjiexian decoction possessed therapeutic effect on hepatic cirrhosis,it had no obvious toxicity and side

Objective To probe into the usage of statins in the patients with coronary artery disease in elderly patients. Methods From Jun 1,2009 to Mar 31,2009 in our hospital, 323 elderly outpatients with coronary artery disease were included in the investigation. The data were statistically analyzed. Results 62.2% of the patients used statins. The statins usage rates (44. 8% ,61.3% ,71.3% ) among three age groups(60 -69 years old,70- 79 years old, and ＞ 80 years old)were significantly different. The rates of statins usage were significantly different between male and female groups. Conclusion The usage of statins as secondary prevention of coronary artery disease varies and there is urgent need to standardize the usage of statins according to the treatment guideline.

Objective To observe therapeutic effects of HuGanJieXian decoction on rats hepatic fibrosis induced by tetrachloride. Methods Rat models of hepatic fibrosis were constructed by intraperitoneal injection of tetrachloride.HuGanJieXian decoction composed of low, middle, and high dose curcumin were given to these rats respectively at the same time. Sho-saiko-to compound treatment group and Fufangbiejiarangan Tablets treatment group were made as positive control groups. After twelve weeks, all rats were executed. Serum samples were kept for measuring serum levels of PC-Ⅲ, LN, and HA. Left livers were extirpated for pathologic examination including H.E and Masson stainings. Grade of hepatic fibrosis were evaluated according to SSS system. The levels of superoxide dismutase (SOD) and malondialdehyde (MDA) of supematant centrifugated from hepatic tissue homogenate were detected. Results Serum levels of PC-Ⅲ, LN, and HA were depressed obviously in decoction groups compared with those of fibrotic group (P<0.05) , especially in the low-dose curcumin group.HuGanJieXian Decoction could increase the level of SOD and decrease the level of MDA (P<0.05) , especially in the low-dose curcumin group. Staining of H. E and Masson showed that degrees of hepatic fibrosis in decoction groups were improved obviously compared with that of the fibrotic group. Conclusion HuGanJieXian Decoction can improve rat hepatic fibrosis, the mechanism of this effect may be associated with protecting hepatic cell membrane and anti- peroxidative damage.

Objective To discuss the clinical values of transabdominal ultrasonic diagnosis of nontraumatic hiatal gastric hernia of esophagus in middle-aged and elderly people.Methods Thirty-two cases were examined with fasting and filing methods in half-sitting,standing,supine and supine right anterior oblique positions.The findings were contrasted with X-ray barium meal examination,endoscopy and operation.Results Twenty-nine cases were of sliding hiatal gastric hernia of esophagus,3 of impacted hernia.The ultrasonic diagnosis coincidence rate was 100%.The signs and symtoms of acoustic images were widening of esophageal hiatus diaphragmatic muscle(≥1.37 cm),echoes of gastric mucosa were found in superior phrenic hernail sac and inside hernial sac.The display rates were 100%,100%,15.6%respectively.Conclusions The transabdominal ultrasonic diagnosis of nontraumatic hiatal gastric hernia of esophagus in middle-aged and elderly people is brief and accurate.

Objective The primary aim of this study was to examine the proportion and natural history of Helicobacter pylori (Hp) negative bleeding peptic ulcers. Methods The study was designed as a multiple-center, case-control study conducted in 14 endoscopy centers in China from April 2006 to March 2007. Each center was expected to recruit 30 peptic ulcer patients with bleeding ( PUB group) and 30 without (PU group). All screened patients with upper gastrointestinal bleeding received endoscopy within 24 hours of admission. Biopsy specimens were taken from the antrum to determine Hp infection by rapid urease test and pathology. Patients with negative Hp infection at first examination were asked to receive urease breathe test (UBT) one month later. Results A total of 617 patients were enrolled with 263 in PUB group and 354 in PU group. There is no significant difference in demographic characters between 2 groups ( P ＞0. 05). The rate of Hp infection in PUB group ( 161/263, 61.2% ) was significantly lower than that in PUgroup (311/354, 87. 9%, P ＜0. 001 ). The incidence of complex ulcer in Hp positive PUB patients was 7.5% ( 12/161 ), which is significantly higher than that in Hp negative PUB patients ( 1/102, 1.0% , P =0. 018). In PUB group, no significant differences were found between Hp positive and negative patients in regarding of age, sex, rates of haematemesis, duodenal ulcer and gastric ulcer, and size of ulcer ( P ＞0. 05 ). Among 102 Hp negative cases in PUB, no positive case was found in UBT one month later. Conclusion We have demonstrated a rise in the incidence of Hp negative bleeding ulcers in China. The idiopathic ulcer was not rare, and might have a higher tendency to cause bleed.

Objective To study the effect of fish oil on calcium oxalate kidney stone formation. Methods The efficacy of unprocessed fish oil in the treatment of 20 hypercakiuric patients with urinary stones was evaluated, after administration of fish oil at dosage of 3000mg daioy of one week.
