ABSTRACT

ObjectiveTo establish a rapid and stable liquid chromatography-mass spectrometry(LC-MS) for simultaneous analysis of 17 chemical components in Gnaphalium affine aboveground parts with flowers, so as to provide experimental basis for improving the quality standard of this herb. MethodUltra performance liquid chromatography-quadrupole/electrostatic field orbitrap mass spectrometry(UPLC-Q-Exactive Orbitrap MS) was used for the quantitative analysis of 17 constituents in 15 batches of G. affine from different origins, the separation was performed on an ACQUITY UPLC® BEH C18 column(2.1 mm×100 mm, 1.7 μm) with the mobile phase of methanol(A)-0.1% formic acid aqueous solution(B) for gradient elution(0-1.0 min, 8%A; 1.0-4.0 min, 8%-26%A; 4.0-9.0 min, 26%A; 9.0-14.0 min, 26%-34%A; 14.0-14.5 min, 34%-45%A; 14.5-15.0 min, 45%-60%A; 15.0-18.0 min, 60%-90%A; 18.0-19.0 min, 90%A; 19.0-19.01 min, 90%-8%A; 19.01-20.0 min, 8%A), the flow rate was 0.3 mL·min-1, the column temperature was 40 ℃ and the injection volume was 2 μL. And the electrospray ionization was used with full scanning in both positive and negative ion modes, and the scanning range was m/z 100-1 000. ResultThe established method has been verified by the methodology and could be used for the simultaneous quantification of 17 components in G. affine. The content ranges of the 17 components(quinic acid, gallic acid, protocatechuic acid, neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, caffeic acid, 1,3-O-dicaffeoylquinic acid, isochlorogenic acid A, isoquercitrin, 1,5-O-dicaffeoylquinic acid, apigenin-7-O-glucoside, astragalin, isochlorogenic acid C, luteolin, apigenin and hispidulin) in 15 batches of G. affine samples was 39.60-179.12, 0.17-0.84, 2.41-8.38, 4.33-31.50, 13.63-180.38, 2.43-14.75, 1.16-19.68, 0.49-5.63, 55.77-445.16, 0.23-10.26, 62.04-530.10, 1.11-18.01, 11.36-90.61, 12.22-65.98, 7.22-69.84, 3.37-45.65, 0.30-2.59 μg·g-1, respectively. The content of organic acids was higher than that of flavonoids in G. affine, and the contents of 1,5-O-dicaffeoylquinic acid, isochlorogenic acid A, quinic acid and chlorogenic acid were higher.

ABSTRACT

Objective:To investigate the clinical characteristics of choledocholithiasis com-bined with periampullary diverticulum and influencing factor for difficult cannulation of endoscopic retrograde cholangiopancreatography (ERCP).Methods:The retrospective case-control study was conducted. The clinical data of 1 920 patients who underwent ERCP for choledocholithiasis in 15 medical centers, including the First Hospital of Lanzhou University, et al, from July 2015 to December 2017 were collected. There were 915 males and 1 005 females, aged (63±16)years. Of 1 920 patients, there were 228 cases with periampullary diverticulum and 1 692 cases without periampullary diverticulum. Observation indicators: (1) clinical characteristics of patients with choledocholithiasis; (2) intraoperative and postoperative situations of patients undergoing ERCP for choledocholithiasis; (3) influencing factor analysis for difficult cannulation in patients undergoing ERCP for choledocholithiasis. Measurement data with normal distribution were represented as Mean±SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M(range) or M( Q1, Q3), and com-parison between groups was conducted using the Wilcoxon rank sum test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. The Logistic regression model was used for univariate and multivariate analyses. Results:(1) Clinical characteristics of patients with choledocholithiasis. Age, body mass index, cases with complications as chronic obstructive pulmonary disease, diameter of common bile duct, cases with diameter of common bile duct as <8 mm, 8?12 mm, >12 mm, diameter of stone, cases with number of stones as single and multiple were (69±12)years, (23.3±3.0)kg/m 2, 16, (14±4)mm, 11, 95, 122, (12±4)mm, 89, 139 in patients with choledocholithiasis combined with periampullary diverticulum, versus (62±16)years, (23.8±2.8)kg/m 2, 67, (12±4)mm, 159, 892, 641, (10±4)mm, 817, 875 in patients with choledocholithiasis not combined with periampullary diver-ticulum, showing significant differences in the above indicators between the two groups ( t=?7.55, 2.45, χ2=4.54, t=?4.92, Z=4.66, t=?7.31, χ2=6.90, P<0.05). (2) Intraoperative and postoperative situations of patients undergoing ERCP for choledocholithiasis. The balloon expansion diameter, cases with intraoperative bleeding, cases with hemorrhage management of submucosal injection, hemostatic clip, spray hemostasis, electrocoagulation hemostasis and other treatment, cases with endoscopic plastic stent placement, cases with endoscopic nasal bile duct drainage, cases with mechanical lithotripsy, cases with stone complete clearing, cases with difficult cannulation, cases with delayed intubation, cases undergoing >5 times of cannulation attempts, cannulation time, X-ray exposure time, operation time were 10.0(range, 8.5?12.0)mm, 56, 6, 5, 43, 1, 1, 52, 177, 67, 201, 74, 38, 74, (7.4±3.1)minutes, (6±3)minutes, (46±19)minutes in patients with choledocholithiasis combined with periampullary diverticulum, versus 9.0(range, 8.0?11.0)mm, 243, 35, 14, 109, 73, 12, 230, 1 457, 167, 1 565, 395, 171, 395, (6.6±2.9)minutes, (6±5)minutes, (41±17)minutes in patients with choledocholithiasis not combined with periampullary diverticulum, showing significant differences in the above indicators between the two groups ( Z=6.31, χ2=15.90, 26.02, 13.61, 11.40, 71.51, 5.12, 9.04, 8.92, 9.04, t=?3.89, 2.67, ?3.61, P<0.05). (3) Influencing factor analysis for difficult cannulation in patients undergoing ERCP for choledocholithiasis. Results of multivariate analysis showed total bilirubin >30 umol/L, number of stones >1, combined with periampullary diverticulum were indepen-dent risk factors for difficult cannulation in patients with periampullary diverticulum who underwent ERCP for choledocholithiasis ( odds ratio=1.31, 1.48, 1.44, 95% confidence interval as 1.06?1.61, 1.20?1.84, 1.06?1.95, P<0.05). Results of further analysis showed that, of 1 920 patients undergoing ERCP for choledocholithiasis, the incidence of postoperative pancreatitis was 17.271%(81/469) and 8.132%(118/1 451) in the 469 cases with difficult cannulation and 1 451 cases without difficult cannula-tion, respectively, showing a significant difference between them ( χ2=31.86, P<0.05). In the 1 692 patients with choledocholithiasis not combined with periampullary diverticulum, the incidence of postopera-tive pancreatitis was 17.722%(70/395) and 8.250%(107/1 297) in 395 cases with difficult cannula-tion and 1 297 cases without difficult cannulation, respectively, showing a significant difference between them ( χ2=29.00, P<0.05). In the 228 patients with choledocholithiasis combined with peri-ampullary diverticulum, the incidence of postoperative pancreatitis was 14.865%(11/74) and 7.143%(11/154) in 74 cases with difficult cannulation and 154 cases without difficult cannulation, respectively, showing no significant difference between them ( χ2=3.42, P>0.05). Conclusions:Compared with patients with choledocholithiasis not combined with periampullary divertioulum, periampullary divertioulum often occurs in choledocholithiasis patients of elderly and low body mass index. The proportion of chronic obstructive pulmonary disease is high in choledocholithiasis patients with periampullary diverticulum, and the diameter of stone is large, the number of stone is more in these patients. Combined with periampullary diverticulum will increase the difficult of cannulation and the ratio of patient with mechanical lithotripsy, and reduce the ratio of patient with stone complete clearing without increasing postoperative complications of choledocholithiasis patients undergoing ERCP. Total bilirubin >30 μmol/L, number of stones >1, combined with periampullary diverticulum are independent risk factors for difficult cannulation in patients of periampullary diverticulum who underwent ERCP for choledocholithiasis.

ABSTRACT

Microfocused ultrasound (MFU) , as a new approach for facial skin tightening and lifting, has been widely applied in recent years. Its action mechanism is that heat can be transmitted to the deep dermis and superficial musculoaponeurotic system through precise and depth-consistent microcoagulation zones, leading to the contraction and remodeling of skin collagen without damage to the epidermis. MFU has high safety with few serious adverse reactions. However, there are still doubts whether it can lead to subcutaneous scar formation, the risk of lipolysis, or nerve, vessel and eye injuries, etc. Appropriate use and selection of patients can minimize the occurrence of these rare adverse reactions as much as possible.

ABSTRACT

BACKGROUND:Three dimensional finite element analysis is widely used in orthopedics, but research in the knee flexion movement is not much. OBJECTIVE:To analyze biomechanical properties of knee flexion using finite element analysis.METHODS:Three dimensional finite element models and models of knee flexion at 30 degrees, 60 degrees and 120 degrees were established. Femoral forward movement, femur inward movement, tibia internal rotation and tibia vara were analyzed at different flexion angles. RESULTS AND CONCLUSION:(1) When knee flexion was at 30 degrees, 60 degrees and 120 degrees, the femur had backward movement. The backward movement value was larger at 60 degrees than at 30 and 120 degrees (P0.05). (2) The femur had outward movement at 30 degrees, and inward movement at 120 degrees. The inward movement value was significantly larger at 120 degrees than at 30 and 60 degrees (P0.05). (3) Tibia internal rotation was not significantly different at 30, 60 and 120 degrees of flexion (P>0.05). (4) Tibia vara was found at 30, 60 and 120 degrees of flexion, but the tibia vara was not obvious at 120 degrees. The tibia vara was maximum at 60 degrees, and significantly higher than that at 120 degrees (P0.05). (5) These findings verify that backward movement was most obvious at 60 degrees. Femur inward movement was most large at 120 degrees. Tibia internal rotation was noticeable at 30 and 120 degrees. Tibia vara was remarkable at 60 degrees.

ABSTRACT

BACKGROUND:There are studies on three-dimensional finite element analysis of total knee replacement, but few research concerns contact pressure and contact area inside and outside polyethylene liner of fixed prosthesis and rotating platform prosthesis in total knee replacement. OBJECTIVE:To explore the contact pressure and contact area inside and outside polyethylene liner of fixed platform prosthesis and rotating platform prosthesis in total knee replacement. METHODS:We established three-dimensional finite element models of fixed platform prosthesis and rotating platform prosthesis in total knee replacement and compared contact pressure and contact area inside and outside polyethylene liner of fixed platform prosthesis and rotating platform prosthesis in total knee replacement. RESULTS AND CONCLUSION:The peak contact pressure inside and outside polyethylene liner of fixed platform prosthesis and rotating platform prosthesis in total knee replacement was minimum at 0° of genuflex. The peak contact pressure inside polyethylene liner was higher than that outside polyethylene liner of fixed platform prosthesis and rotating platform prosthesis in total knee replacement at 0°-90° of genuflex (P<0.05). The peak contact pressure inside and outside polyethylene liner of fixed platform prosthesis was higher than that of rotating platform prosthesis in total knee replacement at 60°-120° of genuflex (P<0.05). The contact area inside and outside polyethylene liner of fixed platform prosthesis and rotating platform prosthesis in total knee replacement was maximum at 0° of genuflex. The contact area inside polyethylene liner of fixed platform prosthesis in total knee replacement was lower than that of outside at 0°-30° of genuflex (P<0.05). The contact area inside polyethylene liner of fixed platform prosthesis in total knee replacement was lower than that of outside at 0°-90° of genuflex (P<0.05). The contact area inside and outside polyethylene liner of fixed platform prosthesis was lower than that of rotating platform prosthesis in total knee replacement at 30°-120° of genuflex (P<0.05). These results suggested that peak contact pressure inside polyethylene liner of fixed and rotating platform prostheses was higher than that outside in total knee replacement, and the inside contact area was lower than that of outside. Inside and outside contact pressure of the rotating platform prosthesis was lower than that of fixed platform prosthesis. Inside and outside contact area of the rotating platform prosthesis was higher than that of fixed platform prosthesis.

ABSTRACT

BACKGROUND:A variety of factors contribute to biliary injury that is difficult to be repaired. Stent implantation is extensively used for bile duct injury, but either scaffolds made by metal or plastics can lead to certain adverse reactions. OBJECTIVE:To explore the biological characteristics of a novel biodegradable scaffold and its repair effects on bile duct injury. METHODS:The biological characteristics of the novel biodegradable scaffold were detected by fresh bile, and its degradation was observed at different time points. Thirty Bama mini pigs were included and were randomly divided into observation group (n=15) and control group (n=15). After bile duct injury models were prepared, the control group was subjected to the bile duct interrupted suture, while the observation group was subjected to the novel biodegradable scaffold combined with omentum majus. The biological properties of the scaffolds were observed. Hepatic enzymes and serum total bilirubin levels were detected, as wel as hematoxylin-eosin staining, Masson staining and immunohistochemistry detection ofα-smooth muscle actin were performed. RESULTS AND CONCLUSION:Before and 1, 3 and 6 months after surgery, hepatic enzymes and total bilirubin of two groups were detected, and neither intra-group nor intergroup comparisons had significant differences (P>0.05). Hematoxylin-eosin staining and Masson staining revealed that inflammatory reactions and fiber hyperplasia at the anastomotic site in the observation group were lighter than those in the control group at different time points after surgery. Theα-smooth muscle actin-positive scores in both two groups were in a rise at 1 and 3 months after surgery, and peaked at the 3rd month, and then began to decline. Moreover, theα-smooth muscle actin-positive scores in the observation group were significantly lower than those in the control group at 3 and 6 months after surgery (P<0.05). These results show that the novel biodegradable scaffold has good biological characteristics and can obtain ideal repair effects in the bile duct injury.

ABSTRACT

BACKGROUND: Renin-angiotensin-aldosterone system existed in bone tissue. Recent studies on antihypertensive drugs found that angiotensin converting enzyme inhibitor type antihypertensive drug was possibly effective for osteoporosis. Perindopril is one of the commonly used antihypertensive drugs. Whether perindopril affected bone metabolism or could be used in anti-osteoporosis has not been reported. OBJECTIVE: To observe effects of perindopril on bone metabolism in a rat model of osteoporosis induced by retinoic acid. METHODS: Fifty Sprague-Dawley rats were randomly divided into five groups, with ten in each group. In the model group and each perindopril groups, rats were intragastricaly administered retinoic acid solution 80 mg/kg per day. After successful model establishment, rats in different perindopril groups were intragastrical y administered perindopril 2, 4 and 8 mg/kg per day, once a day, for 42 consecutive days. In the normal control and model groups, rats were given an equal volume of distil ed water. Serum calcium, phosphorus, alkaline phosphatase, bone mass and bone mineral density were detected in each group. Expression of bone specific alkaline phosphatase and tartrate-resistant acid phosphatase mRNA in bone tissue was determined. RESULTS AND CONCLUSION: Compared with the model group, after treatment with perindopril, serum calcium and phosphorus levels were increased, alkaline phosphatase activities were significantly decreased, bone mass and bone mineral density were obviously increased in rats with retinoic acid-induced osteoporosis. Expression of bone specific alkaline phosphatase mRNA was higher in the perindopril 8 mg/kg group than in the perindopril 2 and 4 mg/kg groups and model group. Tartrate-resistant acid phosphatase mRNA expression was higher in the perindopril 8 mg/kg group than in the model group. These results indicated that perindopril could improve partial bone metabolic biochemical markers in osteoporosis rats, promoted bone formation by up-regulating bone specific alkaline phosphatase mRNA expression, and had a certain preventive effect on retinoic acid-induced osteoporosis.

ABSTRACT

In China, medical system reforms have made an obvious achievement in recent years .However, lots of urgent problems still exist.Doctors are not satisfied with their working environment.The high-pressure job with low remuneration reduces doctors'enthusiasm for work.Meanwhile, both the threat to personal safety and disrespect from patients bring negative effects to doctor's physical and mental health .The main factors causing this situation include the leaky health care system , the incomplete health -care legislation, the misleading reports and the poor medical knowledge of patients .Therefore, some countermeasures should be taken to solve problems mentioned above and the construction of medical ethics should be strengthened at the same time .

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the correlation between CT image presentations and biochemical indexes in adrenal adenomas and pheochromocytomas.</p><p><b>METHODS</b>We retrospectively analyzed the CT features, cortisol rhythm, supine and orthostatic hypertension and 24-h urine methoxy in 209 patients with benign adrenal tumors. The relationship between CT findings and the biochemical indexes were analyzed in patients with different benign adrenal tumors.</p><p><b>RESULTS</b>The 209 cases analyzed included 53 cases of cortisol adenoma, 65 cases of aldosterone adenoma, 45 cases of non-functional adenoma and 46 cases of pheochromocytomas. The plain CT scan values of the 4 groups were 17.25 ± 1.81, 14.52 ± 1.57, 12.20 ± 2.05, 42.42 ± 0.97 HU, enhanced CT values (arterial phase) were 47.82 ± 3.07, 39.23 ± 2.37, 45.35 ± 6.46, and 104.93 ± 5.84 HU, respectively, and the differences between CT scan and enhanced CT values were 30.58 ± 2.29, 24.71 ± 1.55, 33.15 ± 5.18, and 62.51 ± 5.73 HU, respectively. In cortisol adenoma group, cortisol levels measured at 16:00 and 24:00 were positively correlated with plain CT scan value (r=0.506, P=0.0001; r=0.504, P=0.0001) and enhanced CT value (r=0.514, P=0.0001; r=0.554, P=0.0001). In pheochromocytoma group, plain scan CT value and the difference between plain and enhanced CT scan value were correlated with 24-h urine methoxy adrenaline (Rho;=0.342, 0.350; P=0.020, 0.017, respectively) and norepinephrine (Rho;=0.419, 0.412; P=0.004, 0.004, respectively).</p><p><b>CONCLUSION</b>Plain and enhanced CT scan values and their combination have important value in differential diagnosis of adenoma and pheochromocytoma tumor, CT values combine with biochemical indexes can reduce misdiagnosis and missed diagnosis of pheochromocytoma.</p>

ABSTRACT

BACKGROUND:To reduce the amount of bleeding and the amount of hemoglobin after total knee replacement has been a key project in the clinical research in the division of bone and joint. Currently, ice therapy has been widely used in the clinic for tissue sweling and pain due to various physical and chemical factors. OBJECTIVE:To investigate the risk factors of postoperative hemoglobin after total knee replacement and discuss the effects of ice intervention. METHODS: 240 patients with osteoarthritis based on the random draw principles were equaly divided into the treatment group and the control group. The general information, disease status, diagnosis and treatment and prognosis of the two groups were investigated. Al patients were actively subjected to artificial total knee replacement. On the basis of the treatment in the control group, the treatment group received ice intervention at 2 hours after replacement for 7 consecutive days. RESULTS AND CONCLUSION:The postoperative hemoglobin decrease occurred in 34 patients, with the incidence of 14.2% among 240 patients at 7 days after replacement. Multivariate logistic regression analysis results showed that age, no ice treatment, body mass index were the main risk factors for hemoglobin decrease after total knee replacement (P 0.05). Results verify that clinical application of total knee replacement facilitated the knee recovery in patients with osteoarthritis, but hemoglobin decrease and bleeding existed. Active ice intervention can reduce the risk and relieve postoperative pain.

ABSTRACT

measured to compare the correlation between the changes of T lymphocyte subsets before and after operation and the change of platelet. Results Thirty-one patients were underwent laparoscopic splenectomy. The T lymphocyte subsets and CD3 + ,CD4 + and CD3 + / CD4 + in all patients showed an increase trend as the time prolonged after operation,and the differences were significant( F = 6. 91,3. 93,4. 18;P = 0. 023,0. 004,0. 011). While the ratio of CD3 + / CD8 + and CD3 + CD4 + / CD3 + CD8 + were decreased as time increased,and differences were statistically significant( F = 2. 59,3. 67;P = 0. 001,0. 002). They were related with platelet change after operation and correlation statistics analysis showed R values were 0. 332,0. 271,0. 345,- 0. 119,- 0. 164,and the P value were 0. 039,0. 021,0. 002,0. 017,0. 023. Conclusion ITP patients have the imbalance of T lymphocyte subsets,and splenectomy can improve the imbalance of T lymphocyte subsets in patients with ITP. T lymphocyte subsets may serve as a reference index to indicate the prognosis of the patients.
