ABSTRACT

Objective:To compare the clinical effects of 4 kinds of neurocutaneous perforator flap with vascular anastomosis for repair of hand and foot wounds.Methods:From January, 2005 to September, 2019, 112 patients with hand and foot wounds were treated, there were 78 cases of fingers, 11 cases of first web, 5 cases of palm, 6 cases of hand and 12 cases of foot. The defect area was 2.0 cm×1.5 cm-21.0 cm×12.0 cm. All 112 cases were repaired by neurocutaneous perforator flaps anastomosed with blood vessels. Types of flap were applied: Radial collateral artery perforator flap (with posterior cutaneous nerve of forearm) in 30 cases. The flap area was 5.0 cm×2.0 cm-13.0 cm×6.0 cm. Superficial peroneal artery flap (without superficial peroneal nerve) anastomosed with blood vessels in 15 cases. The flap area was 2.5 cm×2.0 cm-9.0 cm×6.0 cm. Lateral superficial sural artery perforator flap (with superior sural cutaneous nerve) in 26 cases. The flap area was 2.5 cm×1.8 cm-7.0 cm×5.0 cm. Peroneal artery perforator flap (with middle and lower sural nerve) in 41 cases. The flap was harvested with area of 2.5 cm×1.8 cm-23.0 cm ×14.0 cm to repair the wounds of feet, back of hands, first web, palm and fingers. CTA images were observed in 40 clinical patients, and the occurrence rate of radial collateral artery, superficial peroneal artery, superficial lateral sural artery, and peroneal artery were measured. Anastomosis cutaneous nerve in 97 cases, and no cutaneous nerve anastomosis 15 cases (superficial peroneal artery flap).Results:The peroneal artery perforator flap (41 cases) and radial collateral artery perforator flap (30 cases) were harvested. The incidence of perforator vessels was both 100%, and incidence of superficial sural artery was 80.8% (21/26 cases). In the other 19.2% (5/26 cases), the superficial medial sural artery was replaced by too thin vessels. The utilization rate of superficial peroneal artery was 60.0% (9/15 cases), the other 40.0% (6/15 cases) were converted to peroneal artery perforator flap. All flaps survived except 1 case of superficial perforator flap of lateral sural artery, which underwent necrosis at the distal end and healed after dressing change. One hundred and one cases were followed-up, including 90 cases for repairing soft tissue defects in hands and 11 cases in feet. The followed-up time ranged from 12 to 120 months, with an average of 36.6 months. There were 40 cases with excellent function, 45 cases with good function and 5 cases with fair function. There were 78 cases of cutaneous nerve anastomosis of hand flap, and the sensory function was above S 3 level. There were 12 cases without anastomosis of cutaneous nerve of hand flap, and the sensory function reached S 3 level in 3 cases and S 2 level in 9 cases. In 11 cases, the cutaneous nerve was anastomosed to repair the soft tissue defect of the foot, and the sensory function was above S 3 level. The radial collateral artery perforator flaps were relatively bulky and needed to be treated by fat removal. The other 3 kinds of three flaps were not bulky. Conclusion:The perforating vessels of peroneal artery and radial accessory artery have larger diameter and easy to harvest. The superficial peroneal artery and the lateral superficial sural artery are relatively small in caliber, especially the superficial peroneal artery. Among the 4 kinds of cutaneous nerve nutrient vascular flaps, the radial accessory artery perforator flap was the most bloated. Sensory nerve innervation flaps were found in the upper segment of lateral sural cutaneous nerve, posterior forearm cutaneous nerve and middle and lower segment of sural nerve. The superficial peroneal artery perforator flap was accompanied by superficial peroneal nerve that did not send cutaneous branches into the flap. The upper segment of superficial peroneal nerve was only a passing nerve.

ABSTRACT

Objective:To compare the application and results in repairing wounds on shank and medial malleolus by perforator pedicled middle and lower third of posterior tibial flap, saphenous neurovascular flap and posterior tibial artery perforator plus saphenous neurovascular (double blood supply) flap.Methods:Clinical data of 60 patients with wounds on shank and medial malleolus and treated between August, 2015 and December, 2018 were analyzed. Among the patients, 25 were treated with perforator pedicled middle and lower third of posterior tibial flaps, 15 with saphenous neurovascular flaps, and 20 with double blood supply flaps. The data of surgery, survival of the flaps, texture and swelling of the flaps, patient satisfaction and scores set by American Orthopaedic Foot and Ankle Society(AOFAS) were collected. Statistic analysis was carried out to compare observations among the 3 groups.Results:Postoperative followed-up was 6 to 24(average 13.4) months. One flap suffered insufficient blood supply in the group of perforator pedicled middle and lower third of posterior tibial flaps, 2 flaps suffersd necrosis and skin graft was carried out in reverse saphenous nerve neurocutaneous flaps group. In double blood supply flaps group, 2 flaps appeared purple after surgery, and improved after removing the pedicle sutuer, and flaps became swelling and received secondary repair. All AOFAS scores (93.8, 93.3 and 92.8, respectively) and patient satisfaction were high in all 3 groups.Conclusion:All 3 types of flap are able to be used in repairing the soft tissue defect on shank and medial malleolus. The inclusive of saphenous nerve should be determined in intraoperation according to the presence and size of the perforator. If artery perforation is reliable, the use of posterior tibial artery perforator flap in wound repairing will deliver satisfactory outcomes in terms of blood supply and appearance of the flap. For the wider area of wound, a flap with double blood supply is preferred.

ABSTRACT

Objective To investigate the health literacy level and health related behavior of high school students in Xuhui District of Shanghai, and to provide basis for health literacy intervention. Methods Using qualitative and quantitative methods, the quantitative part adopted the multi-stage stratified sampling method.A total of 355 aged 15-18 from senior high schools in Xuhui District were selected for face-to-face survey.The qualitative part adopted the form of group interviews, and 20 students from two senior high schools in Xuhui District were selected for interviews. Results The health literacy level of high school students in Xuhui District was 27.32%, which was lower than that of adults in the same period.Among the three dimensions, the level of basic knowledge and concept literacy was the highest, followed by the level of health basic skills literacy, the level of healthy lifestyle and behavior literacy was the lowest; among the six types of health problems, the level of infectious disease prevention literacy and basic medical literacy was at a low level.Statistical analysis of the correct answer rate showed that the answer rate of various questions in the health literacy survey was quite different.Further analysis of the health-related behavioral characteristics of high school students showed that most students had correct health concept and awareness of health change, but they encountered resistance in the process of knowledge transformation into action, which mainly came from academic burden, school education, peer influence and so on.The main channels for high school students to obtain health-related information were classroom, parents, school and various media.They had a high degree of trust in medical professionals and encountered difficulties in seeking health information. Conclusion The health literacy level of senior high school students in Xuhui District of Shanghai needs to be improved.We should explore a health intervention model more suitable for the behavioral characteristics of this group weak links in their health literacy.

ABSTRACT

Objective:Metabolomics was used to analyze the brain tissue samples of model mice with chronic unpredictable mild stress (CUMS) depression, in order to find out the differential metabolites related to depression and to explore the possible antidepressant mechanism of iridoid part of Valerianae Jatamansi Rhizoma et Radix (IEFV). Method:Forty-two Kunming mice were randomly divided into 6 groups, including the normal group, the model group, the fluoxetine group (2.5 mg·kg-1) and the IEFV low, medium, and high dose groups (doses were 5.73, 11.47, 22.94 mg·kg-1, respectively). The behavioral and biochemical indicators of CUMS model mice were used for pharmacodynamic evaluation with IEFV and a positive drug (fluoxetine) as the intervention drugs. Then, the effect of IEFV on endogenous substances of the brain tissue in CUMS model mice were analyzed by nuclear magnetic resonance hydrogen spectrum (1H-NMR) metabolomics, and multivariate statistical analysis was used to identify the differential metabolites and to enrich the metabolic pathways involved in the differential metabolites. Result:After modeling, the immobility time of the model mice increased significantly, their sucrose preference rate and the excitatory neurotransmitters [5-hydroxytryptamine (5-HT) and norepinephrine (NE)] decreased significantly, indicating the success of modeling. The depression was relieved after IEFV administration, mainly manifested by the recovery of the immobility time, sucrose preference rate and the excitatory neurotransmitters (5-HT and NE). Principal component analysis (PCA) of endogenous metabolites in brain tissue showed that the model group could be significantly separated from the normal group, while the IEFV groups and fluoxetine group all showed a trend of deviating from the model group to the normal group, which was consistent with the behavioral results. The results of orthogonal partial least squares discriminant analysis (OPLS-DA) showed that there were 16 different metabolites between the model group and the normal group, including 12 water-soluble metabolites and 4 liposoluble metabolites. Seven potential metabolism pathways were obtained through MetPA analysis, including metabolism of phenylalanine, metabolism of phenylalanine, tyrosine and tryptophan, metabolism of taurine and hypotaurine acid, metabolism of alanine, aspartic acid and glutamic acid, biosynthesis of valine, leucine and isoleucine, metabolism of D-glutamine and D-glutamate and tricarboxylic acid cycle (TCA). IEFV-high dose group could significantly recall 11 differential metabolites. Conclusion:IEFV may play an antidepressant role mainly by affecting energy metabolism, amino acid metabolism and neurotransmitter levels, which provides a reference for further study on the antidepressant mechanism of IEFV.

ABSTRACT

Objective:To compare clinical characteristics of orthopedic trauma patients between the patients during pandemic of corona virus disease 2019 (COVID-19) and those beyond the pandemic period and analyze the factors influencing fracture site changes during pandemic of COVID-19.Methods:A retrospective case-control study was made on data of 1 048 patients with fractures hospitalized in Third Hospital of Hebei Medical University treated from January 20, 2020 to February 25, 2020 (pandemic period group) and from January 31, 2019 to March 9, 2019 (beyond pandemic period group). There were 232 patients in pandemic period group, including 121 males (52.2%) and 111 females (47.8%), with age range of 1-100 years [(47.9±26.3)years]. There were 816 patients in beyond pandemic period group, including 454 males (55.6%) and 363 females (44.5%), with age range of 1-96 years [(47.3±23.9)years]. Fracture sites were compared between the two groups. Age, sex, occupation, cause of injury, history of basic medical diseases, location of fracture, residence, marital status and other factors among the patients with low limb fractures and other fractures in pandemic period group were analyzed using the Logistic regression analysis.Results:Incidence of limb fractures in pandemic period group (69.4%, 161/232) was significantly higher than that in beyond pandemic period group (59.8%, 488/816) ( P<0.05), while the incidence of whole-body multiple fractures in pandemic period group (8.2%, 19/232) was significantly lower than that in beyond pandemic period group (13.6%, 111/816) ( P<0.05). Univariate analysis showed that female, middle or older age, farmers, low-energy injury, basic medical disease, staying at home were risk factors for limb fracture during pandemic ( P<0.05). Multivariate Logistic regression analysis showed low-energy injury ( OR=8.264, P<0.01) was an independent risk factor for limb fracture during pandemic. Conclusions:Compared with the beyond pandemic period, some location of fracture is changed and incidence of limb fracture is increased during pandemic. Low energy injury is an independent risk factor of limb fracture during the pandemic.

ABSTRACT

Objective: To predict the possible quality markers of ginseng in the treatment of heart failure. Methods: The ginseng chemical information was used to predict its putative targets related to heart failure by TCMIP V2.0 and the protein-protein interaction (PPI) network was constructed. The key targets of drug intervention on heart failure were enriched. The interaction network of chemical components-key targets-pathways was constructed to obtain the main components acting on these key targets, which are related to drug efficacy. According to the five principles of quality markers identification, we analyzed the quality markers of ginseng in the treatment of heart failure. Results: A total of 63 key targets were obtained for ginseng in the treatment of heart failure, including 63 putative drug targets and two targets related to disease. ATP1A1 and ADCY2 are the common targets associated with the drug and disease. The common targets of ATP1A1 and ADCY2 may be the key targets of drug acting on disease. The main components of ginseng acting on these common targets were screened out, and then we have determined the possible quality markers of ginseng for the treatment of heart failure based on the five principles of quality markers. Conclusion: We obtained the possible quality markers of ginseng in the treatment of heart failure, including ginsenoside Rg1, ginsenoside Re, ginsenoside Rf, and ginsenoside Rb2, which provided the basis for our deeper research of ginseng in the treatment of heart failure.

ABSTRACT

AIM:To comparatively analyze the effect of wavefront aberration or corneal topography guided laser-assisted in situ keratomileusis (LASIK) on the visual quality in patients with myopia after surgery. METHODS: During the period of January 2016 to January 2017, 100 patients (a total of 200 affected eyes) with myopia in our hospital were selected as the subjects, and they were randomly divided into Group A and Group B with 50 cases in each group. Before surgery, the eyes were examined and LASIK was performed. During surgery,the corneal stroma of eyes in Group A was cut individually according to the results of wavefront aberration examination while the individual cutting in Group B was performed according to the data of corneal topography. The visual acuity and visual quality were compared between the two groups after surgery. RESULTS: There was no significant difference of the visual acuity between the two groups before surgery (P>0.05). The Log MAR uncorrected visual acuity (UCVA), Log MAR BCVA and diopter were significantly improved at 6mo after surgery (P<0.05), and the diopter of Group A at 6mo after surgery was lower than that of Group B (P<0.05). There was no significant difference of contrast sensitivity (CS) between the two groups before surgery (P>0.05). But CS of different optotypes in two groups at 3mo after surgery were all better than those before surgery (P<0. 05). There was no significant difference between the two groups in CS under the bright and non-glare condition at 3mo after surgery (P>0.05). However, CS of Group A under bright glare, dark with glare and dark without glare states were significantly better than those of Group B (P<0. 05). There was no significant difference of detection results of wavefront aberrations between the two groups before surgery(P>0 05). At 3mo after surgery, the total aberrations, total higher-order aberrations,comatic aberrations and spherical aberrations significantly increased in two groups (P<0.05), and the increase in Group A was obviously lower than that in Group B (P<0.05). CONCLUSION: Both of wavefront aberration and corneal topography guided individualized excimer surgery can significantly improve the visual acuity of patients with myopia, but the former has more advantages in improving the visual quality.

ABSTRACT

Objective@#To investigate the development status and risk factors of infants and toddlers in rural China.@*Methods@#In this cohort study, 603 infants (6-12 months of age, Phase Ⅰ) in the rural areas of QinLing-Bashan (Qin-Ba) in Shaanxi were recruited in the control group that received no intervention from April 2013 to October 2015. Three follow-up visits were performed every six months (Phase Ⅱ(12-18 months of age), Phase Ⅲ (18-24 months of age) and Phase Ⅳ(24-30 months of age)). In all the 4 phases (Ⅰ-Ⅳ), general data of the children and the families were collected by questionnaires, early childhood growth and development were assessed by door to door visits, children's hemoglobin levels were determined by laboratory tests, and the cognitive and motor development screening was conducted by the Bayley Scales of Infant and Toddler Development. Logistic regression was used to analyze the risk factors affecting the development of infants and toddlers in rural areas and the data were analyzed in terms of risk factors from infants, guardians and family.@*Results@#Phase Ⅱ, Phase Ⅲ and Phase Ⅳ survey recruited 497, 483 and 486 participants respectively. The incidences of cognitive impairment (mental development scores<80) in rural areas of southern Shaanxi were 13.4% (81/603) in Phase Ⅰ(6-12 months), 20.1%(100/497) in PhaseⅡ(12-18 months), 42.9% (207/483) in Phase Ⅲ(18-24 months) and 50.4%(245/486) in Phase Ⅳ(24-30 months) respectively, which showed a significant increase with age (χ2=233.40, P<0.01); the incidences of psychomotor impairment (psychomotor development scores<80) of Phase Ⅰ, Phase Ⅱ, Phase Ⅲ and Phase Ⅳ were 25.0% (151/603), 26.8% (133/497), 8.3% (40/483) and 11.9% (58/486), which showed a significant decrease with age (χ2=87.08, P<0.01). Multivariate logistic regression analysis showed that the leading risk factor of the cognitive development of 24-30-month-old children was the mothers' poor education background (≤9 years of school education) (OR=2.56, P<0.01), and the main risk factors affecting psychomotor development were the mothers' poor education background (≤9 years of school education) (OR=2.64, P<0.05) and growth retardation (OR=2.95, P=0.07).@*Conclusions@#The early childhood development (especially cognitive development) in the rural areas of Qin-Ba in Shaanxi of China is not optimistic. More attention should be paid to the early childhood development in rural China, especially to the development of children from the mothers with poor education background.

ABSTRACT

Objective To explore how to overcome the difficulties during two paddle anterolateral thigh flap harvest. Methods From January, 2009 to December, 2015, the harvest of two paddle anterolateral thigh flap was encountered difficulties during surgery in 8 cases, which were 7 males and 1 female. The age was ranged from 16 to 48 years old, with averaged of 32.8. Six patients presented with one defect, and 2 patients presented with two defects. The skin defects ranged from 60-247 cm2. The number of the flap perforator, vascular source, flap pattern and out-comes was recorded. All patiants were followed-up at regular intervals. Results All of 8 flaps were converted suc-cessfully during surgery. Only 1 perforator was found in 4 cases. The flap was converted to sigle perforator flap. The dornor site was covered by skin graft. Two perforators from different origins were found in 2 cases, and the flap was converted to sequential chimeric flap. Two perforators from descending branch and transverse branch respectively were found in 1 case, and the flap was converted to combined anterolateral thigh and tensor fascia lata flap. Only 1 perfora-tor was found in 1 case, which the distal defect was small sized, the flap was converted to deepithelialized two paddle flap. The flap ranged from 78-288 cm2. Venous compromise was happened in 1 case, and the flap survived after reex-ploration surgery. Local infection was found in 2 cases, and cured with wound dressing. Other flaps were survived un-eventfully. At donor site, 1 case wound dehiscence and 1 case local infection, both of which underwent debridement and healed. All patiants were followed-up for 7-21(mean, 11.5)months. The flaps had satisfactory appearance and soft texture. Conclusion When it is difficult to harvest two paddle anterolateral thigh flap during surgery, the flap need to be converted rationally based on the characteristics of the defect, the number of the flap perforator, and the vascular origins.

ABSTRACT

Objective To evaluate surgical treatment of chronic tibial osteomyelitis of Cierny-Mader type Ⅳ with Ilizarov technique and lesion osteotomy. Methods From January 2010 to May 2016, 39 patients with chronic tibial osteomyelitis of Cierny-Mader type Ⅳ were treated at our center. They were 33 males and 6 females, 8 to 54 years of age (average, 33.8 years). After debridement and lesion osteotomy, the tibia was fixated with Ilizarov external fixator. Bone was transported to the bone defect after corticotomy was performed on the proximal and/or distal tibial metaphyses simultaneously. Bifocal corticotomy was per-formed in 11 cases, proximal corticotomy in 21 cases, and distal corticotomy in 7 cases. The transport began 3 to 5 days after operation at a speed of 0.5 to 1.0 mm/d initially. The speed was lowered according to the bone healing and pain. Radiographic examination was done every 2 weeks to observe transporting deviation and osteogenesis in the transporting area. The transporting was adjusted whenever any abnormality was observed. The bone transporting lasted for 50 to 130 days (average, 62.4 days). Results The patients were fol-lowed up for 11 to 49 months (average, 21 months). All the soft tissue wounds healed uneventfully and there was no relapse of osteomyelitis. The bone defects in the 32 cases were reconstructed primarily. Nonunion of fracture ends happened in 5 cases and nonunion of the bone lengthening zone in 2 cases. The 7 cases of nonunion were healed after secondary bone grafting. Malalignment happened in 5 cases, 4 of which responded to timely adjustment of the external fixation and one of which had to receive secondary bone grafting after failure in adjustment of the external fixation. Ankle joint dysfunction occurred in 7 cases, 5 of which re-sponded to functional exercise and 2 of which accepted joint dysfunction because they refused surgery after unsatisfactory functional exercise. Pin tract infection of different severities occurred in 9 cases, one of which was treated by replacement of the K-wires under local anesthesia and the other 8 of which responded to rein-forced dressing change. Conclusions Chronic tibial osteomyelitis of Cierny-Mader typeⅣcan be treated by Ilizarov technique and lesion osteotomy. However, the Ilizarov technique should be improved because of the risks of multiple complications which can be reduced significantly by strengthening postoperative instruction, nursing, and regular follow-up.

ABSTRACT

Objective To investigate the main risk factors of respiratory complications in patients with cervical spinal cord injury so as to provide reference for early nursing assessment and personalized nursing intervention model. Methods A retrospective case series study was conducted on the clinical data of 303 patients with cervical spinal cord injury admitted to the Third Hospital of Hebei Medical University between January 2015 and September 2016. There were 248 males and 55 females, aged (44.9 ±13.8)years (range, 14-70 years). There were 109 cases at fracture site C14 and 194 cases at C5-8. According to ASIA classification, 131 cases were grade A, 26 cases grade B, 42 cases grade C, and 104 cases grade D. The duration from injury to operation was (23.2 ± 69.9) hours (range, 6-48 hours). Univariate analysis was performed on the risk factors of respiratory complications, including gender, age (14-54, 55-65, and 66-70 years old), occupation, hospital stay, smoking history, previous history, ASIA grade (grades A to D), injury cause, complications (abdominal distension, hyponatremia, hypoproteinemia, and anemia). Multivariate logistic regression was used to analyze the significant risk factors in the univariate analysis so as to further identify risk factors associated with respiratory complications. Results Univariate analysis showed that age (55-65 and 66-70 years), ASIA grade A, ASIA grade B, smoking history, injury cause, complications (abdominal distension, hyponatremia, hypoproteinemia, and anaemia) were related to respiratory complication of patients with cervical spinal cord injury (P <0.05). The gender, occupation, length of hospital stay, and previous history were not associated with respiratory complications of patients with cervical spinal cord injury (P>0.05). Logistic regression analysis showed that age between 55 and 65 years (OR = 3.989, P < 0.05), age between 66 and 70 years(OR =0.301, P<0.05), AISA grade A (OR=30.300, P<0.05), ASIA grade B (OR =5.784, P <0.05), smoking history (OR=5.238, P <0.05), abdominal distension (OR = 1.975, P<0.05), hypoproteinemia (OR =6.212, P < 0.05), and hyponatremia (OR =3.233 <0.05) were independent risk factors for respiratory complications in patients with spinal cord injury. Except for ASIA classification, other factors might be easily ignored by doctors and nurses, leading to poor prognosis of patients. Conclusions Age (above 55 years), ASIA grades A and B, smoking history, abdominal distention, hypoproteinemia, and hyponatremia are the risk factors of respiratory complications in patients with cervical spinal cord injury. Based on the results, early nursing assessment can be carried out and personalized nursing measures can be taken to reduce the incidence of respiratory complications. It can also provide reference for constructing standardized nursing intervention model.

ABSTRACT

Shengmaiyin is widely used in the treatment of arrhythmia and has achieved a good effect. Due to the complexity of traditional Chinese medical formula, the pharmacological mechanism of Shengmaiyin in the treatment of arrhythmia is unclear. In this study, we used the internet-based Computation Platform (www.tcmip.cn) to explore the molecular mechanism. Shengmaiyin was found to treat the arrhythmia by modulating the pathway related to energy metabolism such as carbon metabolism, purine metabolism, carbohydrate metabolism, or by regulating the level of ATP. In this study, we find that the main active drug component in Shengmaiyin may be ginseng.

ABSTRACT

@#AIM: To explore the application effect of fenofibrate combined with 23G minimally invasive vitrectomy in patients with diabetic retinopathy(DR). <p>METHODS: Totally 102 DR patients(102 patients)treated in our hospital from October 2015 to November 2017 were selected and divided into observation group and control group according to random number table, 51 cases in each group. The 23G minimally invasive vitrectomy was performed in all patients. From the 1<sup>st</sup> day after operation, the two groups were treated with related treatment, and the control group was given conventional hypoglycemic, antihypertensive and improved microcirculation treatment. On the basis of the above, the observation group was treated with fenofibrate treatment. Both groups were treated for 3mo. The operation and postoperative basic conditions(operative time, intraoperative blood loss, complication rate, length of stay), the level of blood lipid \〖total cholesterol(TC), triglyceride(TG), low density lipoprotein cholesterol(LDL-C), high density lipoprotein cholesterol(HDL-C)\〗, and the serum levels of related factors \〖lipoprotein associated phospholipase A2(Lp-PLA2), vascular endothelial growth factor(VEGF)\〗 before and after 3mo of operation of two groups were compared. Following up for 6mo after operation, the recurrence rate of two groups of retinopathy was statistically compared. <p>RESULTS: There was no significant difference in operative time, intraoperative blood loss, incidence of complications and length of stay between the two groups(<i>P</i>>0.05). There was no significant difference in the levels of TC, TG, LDL-C and HDL-C between the two groups before operation(<i>P</i>>0.05). After 3mo, the levels of TC, TG and LDL-C in the observation group were lower than those in the control group, and the level of HDL-C was higher than that in the control group, and the difference was statistically significant(<i>P</i><0.05). There was no significant difference in serum levels of Lp-PLA2 and VEGF between the two groups before operation(<i>P</i>>0.05). The serum levels of Lp-PLA2 and VEGF in the observation group were lower than those in the control group 3mo after operation, and the difference was statistically significant(<i>P</i><0.05). There was insignificant difference in visual function and quality of life, sensory adjustment, psychological and social scores and total scores between the two groups before surgery(<i>P</i>>0.05). At 3mo after operation, the scores of visual function and life quality in the observation group were lower than those in the control group, and the difference was statistically significant(<i>P</i><0.05). After follow-up for 6mo, no recurrence occurred in the observation group. The recurrence rate in the control group was 5.9%(3/51), and there was no significant difference between the two groups(<i>P</i>>0.05).<p>CONCLUSION: The combination of fenofibrate and 23G minimally invasive vitrectomy for the treatment of DR can effectively correct the disorder of lipid metabolism, reduce the level of serum Lp-PLA2 and VEGF, so it is beneficial to improve the visual function and quality of life of the patients, but there is no effective data support for reducing the postoperative recurrence rate.

ABSTRACT

Objective:Tacrolimus prolonged-release(PR) formulation is a new once-daily formulation of the calcineurin inhibitor tacrolimus,which is currently used in adult liver or kidney transplant patients,and is also gradually widely used in children with nephrotic syndrome.The present study was undertaken to preliminarily investigate the pharmacokinetic characteristics of tacrolimus PR in pediatric nephrotic syndrome recipients.Methods:This single-center open-label prospective study was performed in pediatric nephrotic syndrome recipients.Pharmacokinetic samples were collected from eight pediatric subjects with nephrotic syndrome from Department of Pediatric Nephrology in Peking University First Hospital between June and August 2011.They followed administration of single oral doses of tacrolimus PR formulation at 0.02 mg/kg (n =2),0.05 mg/kg (n =2) and 0.10 mg/kg (n =4).Blood samples were taken before the dose and 1,2,4,6,8,10,12 and 24 h after drug intake.No other medicines or interacting food or drinks were taken during the study period.Blood concentrations were measured using an enzyme multiplied immunoassay technique.Pharmacokinetic analysis was performed using WinNolin Phoenix software Version 6.0 (Pharsight,Cary,NC,USA).Results:The pharmacokinetic data were best described by a non-compartment model.Pharmacokinetic parameters of tacrolimus PR formulation in the 3 ascending doses groups (0.02 mg/kg,0.05 mg/kg and 0.10 mg/kg) were as follows:the maxi mum drug concentrations (Cm=/D) were (1.7 ± 1.0) μg/L,(3.1 ± 1.9) μg/L,(8.0 ± 3.5) μg/L,respectively;Areas under the drug concentration-time curve (AUCo-∞/D) were (47.2 ± 47.1) h · μg/ L,(84.0 ± 13.1) h · μg/L,(175.6 ± 107.1) h · μg/L,respectively;Oral clearance rates were (0.8±0.9) L/(h·kg),(0.4±0.1) L/(h · kg),(1.9 ±1.3) L/(h · kg),respectively;Body weight normalized distribution volumes were (7.0 ± 3.4) L/kg,(12.4 ± 8.4) L/kg and (73.6 ± 68.6) L/kg,respectively.Both mean Cmax normalized level for the administered dose (Cmax/D) and mean AUC0-∞ normalized level for the administered dose (AUC0-∞/D) were higher in the 0.05 mg/kg dosage group than in the 0.02 and 0.10 mg/kg dosage group.There were two peaks in the drug concentrations in every dose group;a primary peak appeared at the end of about 2 h followed by a small secondary peak at h 12,which was more noticeable in the 0.10 mg/kg dose group than in the two lower dosages.Conclusion:The pharmacokinetic characteristics of tacrolimus PR formulation were initially explored in pediatric patients with nephritic syndrome.The data presented form a basis for subsequent larger scale studies on pharmacokinetics of tacrolimus PR formulation in nephritic syndrome children.

ABSTRACT

Objective To study the radiation injury of rat C6 glioma cell line by high resolution,1 H-nuclear magnetic resonance (1 H NMR) spectroscopy,and to preliminarily investigate its mechanism.Methods Metabolite concentrations in C6 cells were determined by 1 H NMR spectroscopy.Comet assay was used to evaluate DNA damage.Flow cytometry was used to determine the cell cycle and apoptosis rate.Colony-forming assay was used to measure the colony-forming rate and preliminarily investigate the mechanism of radiation injury.The resuhs were analyzed by one-way analysis of variance and Pearson correlation analysis.Results With the increase in radiation dose from 0 Gy to 1,5,10,and 15 Gy,DNA damage was enhanced in a dose-dependent manner (P=0.000-0.690);the percentage of cells in G1 phase increased (P =0.026-0.749);the apoptosis rate significantly increased (all P =0.000);the colony-forming rate significantly declined (P =0.000-0.004);the Lac/Cr ratio significantly decreased (P =0.000-0.015),which had a negative linear correlation with DNA damage parameters (tail length,r=-0.971;%DNA in the tail,r =-0.998;tail moment,r =-0.995) and apoptosis rate (r =0.978).Conclusions 1 H NMR spectroscopy reveals that the change in the Lac/Cr ratio is associated with injury and apoptosis of C6 cells after radiation.1 H NMR spectroscopy has the potential to predict radiation injury of glioma.
