Objective To investigate an effective method for the treatment of biliary ascariasis.Methods A retrospective analysis was performed for the clinical data of 32 patients with biliary ascariasis who were treated in The People's Hospital of Huangmei County from January 1994 to January 2014.All the patients were given spasmolysis,pain management,anti-infective therapy,traditional Chinese medicine syndrome differentiation-based treatment,Chinese materia medica for regulating qi and relieving pain,and ascariasis-relieving and parasite -expelling treatment.Patients were given surgical treatment due to poor response.Results Of all the 32 patients,5 (15.6％) had no response to the ascariasis-relieving treatment with Fructus Pruni Mume decoction and were given surgical treatment,and 27 (84.4％) were cured by Western medicine combined with Fructus Pruni Mume decoction.There were no complications such as acute pancreatitis,perfora tion of the gallbladder,and liver abscess.All the patients were treated with Fructus Pruni Mume decoction regularly after discharge and no patient experienced recurrence.Conclusion Integrated traditional Chinese and Western medicine therapy is effective,safe,and reliable in the treatment of biliary ascariasis and holds promise for clinical application.

Objective To explore a novel improved method of simplified fluid-supplement therapy during the diuresis stage after renal transplantation.Method We adopted an improved fluid-supplement therapy to treat 26 postoperative patients of heterologous kidney transplantation after returning Liger's liquid, 500ml of 5% glucose-salt liquid, and 500ml liger's Compound back to linical wards by means of replenishing 500ml of sodium lactate sodium chloride injection in turn for fluid supplement. In addition, the patients were given originally 10～20ml of 10% calcium glubionate within 12 hours after their operations. Results Based on the results of both blood and urine determination at the first day aftert kidney transplantation, we discovered 2 patients slightly decreased sodium in blood, one displayed hypokalemia,2 patients showed slightly hyperkalemia value than normal referance level. Meanwhile, all patients manifested blood chlorate value between 101?4. Besides, another 7 patients had slightly increased blood suger value. However, no hypernatremia, hypocalcia or hypomagnesemia were found. As a result, all specific gravity ratio value were from 1.010 to 1.015 aparting from hemobilinuria existed in some patients. Conclusion The succesessful use of the new fluid-supplement therapy could effectively avoid unnecessary repeated haemospasia analysis for mornitoring and adjusting the balance of electrolyte, which could remarkably simplify and faciliate the postoperative management of renal transplantation.

Cholesterol polyposis of the gallbladder is a metabolic disorder of cholesterol and characterized by the deposit of cholesterol esters and other lipids in the lamina propria of gallbladder.The pathogenesis is complicated which may involve various factors,and probably associated with the alteration of polygene expression,but at this moment the true nosogenesis is still unclear.

Objective To study the association between blood pressure variability and left ventricular hypertrophy in elderly isolated systolic hypertension.Methods Active blood pressure was applied to measure average BP,24 hour daytime and night BP variability,meanwhile,left ventricular interior diameter,the thickness of interventricular septum and left ventricular posterior were taken using echocardiagram so as to measure left ventricular weight( LVW) and left ventricular weight index (LVMI) in 31 elderly isolated systolic hypertension and 24 controls.Results BP variability, LVM and LVMI in 31 cases were higher than that of 24 controls.Conclusion BP variability and average BP are related to LVH.

Objective To explore the similarities and differences in amplitude of low frequency fluctuation ( ALLF) between patients with first-episode drug-naive schizophrenia and offspring of schizophrenia patients.Methods ALFF values were estimated by measuring the Blood Oxygen Level-Dependent ( BOLD) signal using resting state function-al magnetic resonance imaging ( rs-fMRI) .The fMRI date were acquired from 23 patients with first-episode drug-naive schizophrenia (SZ), 25 offsprings of schizophrenia patients (OS) and 29 age -and gender -matched health controls ( HC) .The ALFF value of each subject was calculated by MATLAB-based DPARSF software.Results Compared with HC, the ALFF values of SZ and OS were significantly different in the left posterior part of the inferior temporal gyrus, left parahippocampal gyrus, left hippocampus, right postcentral gyrus and bilateral precuneus.The ALFF values were not signif-icantly different between these two groups in the aforementioned regions.Compared with OS and HC, the ALFF values of SZ were significantly different in the left anterior part of the inferior temporal gyrus, left temporal pole and bilateral calcarine cortex.But there was no significant difference between OS and HC.Conclusions The brain function is abnormal in pa-tients with early schizophrenia and offspring of schizophrenia patients.The significant difference of ALFF in the left posterior part of the inferior temporal gyrus, left parahippocampal gyrus, left hippocampus, right postcentral gyrus and bilateral pre-cuneus may suggest the heredodiathesis-related brain functional alterations.Significant difference of ALFF in the left ante-rior part of the inferior temporal gyrus and the left temporal pole bilateral calcarine cortex may suggest the disease-related brain alterations.

Objective To explore the repair effect of the superficial iliac island flap for the hypertrophic scar of mons pubis after burned.Methods From July 2013 to July 2016,the author had treated 26 patients with mons pubis hypertrophic scar after burned.There were 19 males and 7 females among them.The age was from 1 year and 5 months to 10 years old.The scar area was of 6 cm ×5 cm-15 cm ×8 cm.Some of the patients had external genital malformations caused by scar contracture.Surgery removed the scar and completely released the basic shape of the vulva.It had to expand the superficial iliac island flap of 1 cm according to the size of the wound,and sufficient length of vascular pedicle according to the distance from the wound to the flap.The flap was cut in the superficial of the deep fascia,and reserved about 2cm wide fat along the superficial iliac artery.The superficial vein was located in the fat.The wound was covered by the flap,which was rotated directly or through a subcutaneous tunnel.Results Twenty six patients were treated with a single operation and no vascular crisis occurred.All the flaps survived.One patient delayed incision healing due to the high incision tension,and the remaining patients were in primary healing.The postoperative follow-up found that all the flaps had thin thickness,similar color to the surrounding skin,soft texture and feeling.Conclusions There are obvious signs of scarring in the mons pubis area after deep burns,and scar contracture can cause vulvar deformity.The superficial iliac island flap,which has a thin thickness,soft texture,similar color,and can be sutured directly for the donor site,is a good choice to repair the mons pubis hypertrophic scar.

Objective To understand the skeletal metabolism in glucocorticoids-treated children with kidney diseases and to evaluate the role of Alfacalcidol plus calcium supplements.Methods A retrospective self-controlled study was performed in children with kidney diseases,admitted to Department of Pediatrics,Peking University First Hospital from July 2012 to November 2014,and they conformed to the inclusion and exclusion criteria.Inclusion criteria:children with renal diseases were included when they were administered with glucocorticoids,Alfacalcidol and calcium at the enrollment and follow-up,whose proteinuria was in remission or improved on follow-up,and renal function defined by glomerular filtration rate was more than 80 mL/(min · 1.73 m2),and they were followed up for at least 3 months.Exclusion criteria:whereas on follow-up,children with renal diseases were excluded if glucocorticoids was discontinued,or the follow-up period was less than 3 months,and related parameters were not available at the initial and finial visit.Serum levels of calcium,phosphate,alkaline phosphatase,25-hydroxy-vitamin D (25-OH-VitD) were detected,and bone mineral density at the left radius and mid tibia was measured by using quantitative ultrasound at the initial and finial visit.The levels of calcium,phosphate,alkaline phosphatase,25-OH-VitD and bone mineral density were compared between the initial and finial visit.Results A total of 29 cases (23 male,6 female) were recruited.Their ages at study entry were 2.4 to 14.9 years.Underlying disorders were primary nephrotic syndrome(17 cases),IgA nephropathy (4 cases),lupus nephritis (3 cases),purpura nephritis (2 cases),acute glomerulonephritis (1 case),Sjogren's disease(1 case),and autoimmune disease(1 case).At the time of enrollment,the course of disease was 1 to 69 months (median course of disease was 8 months),the duration of using corticosteroid was 0-60 months (median duration was 5 months),and the follow-up time was 92-409 days.The serum calcium,alkaline phosphatase and 25-OH-VitD levels at finial visit[(2.29 ±0.11) mmol/L,(153.21 ±71.00) U/L,and (40.96 ± 11.40) nmol/L,respectively] were significantly higher as compared with those at initial visit [(2.17 ± 0.16) mmol/L,(114.10 ±64.48) U/L,and (31.64 ± 10.99) nmol/L,respectively],and the differences were significant (all P ＜ 0.01),whereas there was no significant difference in serum level of phosphorate between initial and finial visit[(1.45 ±0.25) mmol/L vs.(1.48 ± 0.25) mmol/L] (t =-0.452,P ＞ 0.05).Meanwhile,there was significant difference in serum level of albumin level between initial and finial visit [(31.41 ± 9.31) g/L vs.(42.09 ± 4.00) g/L,t =-3.670,P ＜ 0.001].Compared with baseline assessment,bone mineral density at the left radius and tibia improved or maintained in 24/29 patients,whereas that of 5/29 patients declined.However,compared with initial and finial visit of bone mineral density in all patients(0.09 ± 1.58 vs.0.22 ± 1.07 at the left radius;0.93 ± 1.13 vs.1.00 ± 1.35 at the mid tibia),there was no significant difference (all P ＞ 0.05).Conclusions Bone loss can be prevented by Alfacalcidol plus calcium supplement in glucocorticoids-treated children with kidney diseases.

OBJECTIVETo observe the effects of adipose-derived mesenchymal stem cells (ADSCs) with continous over-expression of glial cell line-derived neurotrophic factor (GDNF) on the motor function recovery and nerve regeneration of sciatic nerve of rats after electrical injury.

METHODSFive SD rats were collected to prepare ADSCs with over-expression of GDNF. One hundred and fifty SD rats were divided into normal control group (N), GDNF-ADSCs group (GA), ADSCs group (A), GDNF group (G), and physiological saline group (P) according to the random number table, with 30 rats in each group. Rats in group N were routinely fed without treatment, and rats in the other 4 groups were inflicted with electrical injury on sciatic nerve of thigh of the right hind leg. Rats in groups GA, A, G, and P were respectively injected with 100 µL suspension of ADSCs with over-expression of GDNF (1 x 10(7) cells per mL), 100 [µL ADSCs suspension (1 x 10(7) cells per mL), 100 µL GDNF solution (100 mg/L) , and 100 µL physiological saline to the surface of the injured nerves immediately after injury. Six rats of each group were collected for measuring hind limb stride from post injury week (PIW) 1 to 8, and morphology of the sciatic nerves was observed in PIW 8. In PIW 4, the protein expression of GDNF of sciatic nerves of the rest rats in each group was determined with Western blotting. Data were processed with one-way analysis of variance, analysis of variance of repeated measurement, and SNK test.

RESULTSCompared with that of group N, the hind limb stride values in groups GA, A, G, and P were significantly lower at each time point (with P values below 0.05). Compared with those of group P, the hind limb stride values in group GA from PIW 3 to 8, in group A in PIW 3, 5, and 7, and in group G in PIW 3, 5, 7, and 8 were significantly longer (with P values below 0.05). The hind limb stride values in group GA from PIW 4 to 8 were respectively (10.83 ± 0.97), (13.25 ± 1.40), (12.86 ± 1.42), (14.06 ± 1.50), and (15.09 ± 1.17) cm, which were significantly longer than those in group A [(8.90 ± 0.82), (9.03 ± 0.57), (9.27 ± 0.36), (9.86 ± 0.36), and (9.52 ± 0.58) cm] and group G [(8.87 ± 0.69), (8.51 ± 1.18), (9.34 ± 0.87), (9.76 ± 0.67), and (9.50 ± 1.22) cm], with P values below 0.05. Compared with that of group N, the number of myelinated nerve fibers of sciatic nerves was obviously decreased in group P but obviously increased in groups GA, A, and G; the diameter of axons was obviously shorter, and the myelin thickness was obviously increased in groups GA, A, G, and P in PIW 8 (with P values below 0.05). The number of myelinated nerve fibers in group GA was 31.2 ± 0.8, which was significantly higher than that in group A (23.7 ± 2.7), group G (22.3 ± 2.7), or group P (9.3 ± 2.8), with P values below 0.05. The diameter values of axons among groups P, A, G, and GA were similar (with P values above 0.05). The myelin thickness of rats in group GA was (3.41 ± 0.34) µm, which was significantly thicker than that in group A [(2.64 ± 0.37) µm] or group G [(2.41 ± 0.34) µm], with P values below 0.05. In PIW 4, the protein expression of GDNF of sciatic nerves was significantly higher in groups P, A, G, and GA than in group N (with P values below 0.05), and the protein expression of GDNF in group GA was significantly higher than that in group P, A, or G (with P values below 0.05).

CONCLUSIONSADSCs over-expressing GDNF protein can obviously promote the motor function recovery and nerve regeneration of sciatic nerve of rats after electrical injury.
