Methods From January 2000 to January 2003,332 patients with gallstones were treated with Qingdanyin and ESWL, compared with 141 patients with routine ESWL. Results The 2-week clean rate(36.14%),one month clean rate(58. 58%),3-month clean rate(68. 98%) ,6-month clean rate(86.75%) of gallstones in the Qingdanyin and ESWL group were much higher than those in routine ESWL patients(14. 92%, 21.02%,35.93%,47.11%,respectively)(P

Objective To study the compatibility of TCM prescriptions of TCM practitioners of all dynasties of Alzheimer disease (AD). Methods Amnesia, forgetting, dementia, and idiot were set as search words to retrieve relevant literature in Encyclopadia of Traditional Chinese Medicine. Prescription information was screened and standardized to build database. Frequency analysis and association rules were used to mine TCM prescriptions and compatibility rules. Results Totally 449 AD related prescriptions were selected, involving 682 Chinese medicinal herbs. The individual herb with the highest frequency was Ginseng Radix Rhizoma (192);the herbal pair with the highest frequency was Ginseng Radix Rhizoma-Polyhalae Radix (182);the herbal combination with 3 Chinese medicinal herbs with the highest frequency was Poria with Hostwood-Ginseng Radix Rhizoma-Polyhalae Radix (79);the herbal combination with 4 Chinese medicinal herbs with the highest frequency was Polyhalae Radix-Ginseng Radix Rhizoma-Poria with Hostwood-Glycyrrhizae Radix et Rhizoma (37). The results of association rules showed that Ginseng Radix Rhizoma-Polyhalae Radix, Ginseng Radix Rhizoma-Glycyrrhizae Radix et Rhizoma, and Ginseng Radix Rhizoma-Poria with Hostwood were commonly used compatibilities in AD related prescriptions. Conclusion Treatment of TCM practitioners in all dynasties for AD mainly chooses Chinese medicinal herbs with the efficacy of tonifying qi and soothing nerves. The compatibilities and combinations are reasonable and with certain representativeness.

Objective To investigate the effect of oral rehydration on hemedynamies and mierocirculatory perfusion in dogs with fatal hemorrhagic shock.Methods Twenty male Beagle dogs 16-20 months old weighing 8-12 ks were subjected to a loss of 40% of the total blood volume,then divided into 3 groups:no rehydration group (group NR,n=8),oral rehydration group(group OR,n=6)and intravenous rehydration group(group IR,n=6).Group NR received no treatment within 24 h after blood-letting.Group IR and OR were given glucose-electrolyte solution (GES) either by gastric tube or by intravenous infusion 3 times volume of the blood loss immediately after the establishment of the model.Then the lactated Ringer's solution,glucose saline and compound amino acid(2 times volume of the blood loss)were started to be given to supplement the physiological consumption from 24 h after blood-letting in each group.The MAP,cardiac index(CI),systemic vascular resistance (SVR),dp/dtmax,and intestinal mucoflal blood flow (IMBF) were determined before blood-letting(T0,baseline) and 2 h (T1),4 h(T2),8 h(T3),24 h(T4),48 h(T5) and 72 h(T6)after blood-letting.The fatality rate within 72 h after blood-letting and urinary output were calculated.Results The fatality rates were 63%,33%and O in group NR, OR and IR respectively, which showed significant difference between the groups (P < 0.05).Compared with the baseline values at To, MAP, CI and dp/dtmax were significantly decreased at T1-6, in group NR,at T1-5 in group OR and at T1-4 in group IR, and SVR was significantly increased, while IMBF decreased at each time point after blood-letting in the three groups ( P <0.05), but no significant change was found in MAP, CI and dp/dtmax at T6 in group IR and OR (P>0.05). MAP, CI, dp/dtmax , IMBF and urinary output were significantly higher, while SVR was significantly lower in group OR and IR than in group NR ( P < 0.05). MAP, CI,dp/dtmax, IMBF and urinary output were signiflcandy lower, while SVR was significantly higher in group OR than in group IR ( P < 0. 05). Conclusion Oral administration of GES 3 times volume of the blood loss within 24 h after fatal hemorrhagic shock can obviously improve the hemodynamics and microcirculatory perfusion, then improve the survival state and have obvious resuscitation efficacy.

Objective To assess the feasibility of heterogeneous acellular dermal matrix(ADM)seeded with adipose derived stem cells(ADSC)for urethroplasty in a rabbit model.Methods ADSC were isolated from a rabbit and expanded in vitro,then identified by flow cytometry.We seeded ADSC onto the ADM and made it into tissue-engineered urethra.12 male rabbits were removed 1 cm urethra and divided into experiment group and control group.There were 6 rabbits in each group.Reconstructed urethra with tissueengineered urethra was used in experiment group,while unseeded ADM were used in control group.Urethrography was performed at 6 months after surgery.The animals were scarified at 3 and 6 months after surgery and the repaired urethra were harvested.H&E staining and immunohistochemical staining were performed with cytokeratin AE1/AE3 and smooth muscle desmin makers.Results The morphology of isolated ADSC was with long spindle cross-links,and had multicentral growth.Flow cytometry showed that the ADSC expressed CD166,CD105,CD90 and CD44,but not expressed CD45 and CD13.The cells could growth well on the ADM and showed good biocompatibility with it.All animals could void normally,urethrography showed there was no significant stenosis.3 months after surgery,the experiment group appeared regenerated smooth muscle but not in the control group,both groups did not regenerate urothelium.At 6 months urothelium and smooth muscle cells could be observed in the experiment group,but only the smooth muscle was evident in the control group.Conclusions By applying tissue engineering methods,we can seed the ADSC onto the heterogeneous ADM and make it into tissue-engineered urethra,which can help improve the reconstructive effect of urethra.

Objective To investigate the effects of delayed fluid resuscitation on hemodynamics and visceral perfusion in dogs with hemorrhagic shock. Methods Fourteen Beagle dogs were prepared for cannulation of carotid artery and jugular vein, and 24 hours later they were subjected to hemorrhagic shock with about 42% of total blood volume exsanguinated. Animals were divided into delayed resuscitation group ( DR group, n = 8) and immediate resuscitation group ( IR group, n = 6) . In the first 24 hours after hemorrhage, dogs in Dr group were given no fluid resuscitation, while those in IR group were immediately given resuscitation with intra-venous glucose-electrolyte solution, of which the volume was three times that of blood loss. In the second 24 hours, all animals had intra-venous fluid resuscitation. The variables of hemodynamics and visceral perfusion were determined before hemorrhage and 2, 4, 8, 24, 48 and 72 hours after hemorrhage under conscious state of dogs. Results After hemorrhage, the mean arterial pressure,cardiac output index, max of left ventricular contractility, blood flow of intestinal mucosa and urinary output greatly decreased and systemic vascular resistance obviously increased in each group compared with those before hemorrhage ( P ＜ 0.05 ) . From 4 hours after hemorrhage, the above measurements of dogs in IR group gradually resumed and reach Oh levels in 72 hours after hemorrhage except systemic vascular resistance index and intestinal blood flow. Whereas those measurements in dogs of DR group kept on worsening, and the levels of mean arterial pressure, cardiac output index, intestinal blood flow and urinary output were significantly lower than those in dogs of IR group ( P ＜ 0. 05 ) . Over 72 hours, five of eight dogs died with anuria in DR, and no animals died in IR group. Conclusion The findings indicate that delayed fluid resuscitation deteriorates hemodynamics, handicapping the restoration of visceral perfusion and increasing mortality in dogs with hemorrhagic shock.

Objective:To evaluate the value of adenosine triphophate (ATP)stress/rest nuclide myocardial perfusion imaging (MPI)in the diagnosis of female patients with coronary heart disease (CHD).Methods:The clinical materials of 47 female suspected CHD patients were retrospectively analyzed,aged from 39 to 74 years,and the average age was (53.7±6.3)years old.All patients were hospitalized and underwent two-day ATP stress and rest nuclide MPI and coronary angiography (CAG)in two weeks. The results and images of MPI and CAG were evaluated by more than 2 attending physicians. Using CAG as the “gold standard”, the diagnostic efficiency (sensitivity, specificity and accuracy) of MPI for CHD was evaluated. Results:Compared with CAG, the sensitivity,specificity and accuracy of ATP stress MPI in diagnosing the female CHD patients were 81.3% (13/16),77.4% (24/31)and 78.7% (37/47)individually;the positive predictive value and negative predictive value were 65.0% (13/20)and 88.9% (24/27).There were no severe adverse effects in the ATP stress test and the incidence of adverse effects was 85.1%.Conclusion:There is a highly diagnostic efficiency of ATP stress MPI in the CHD patients.It can be the first choice of examination methods for screening without injury and diagnosing the myocardial ischemia in the female patients.

OBJECTIVETo compare the vibration parameters in reducible anterior disc displacement and symptomless youth, and explore the clinical diagnostic value of frequency spectrogram of temporomandibular joint (TMJ) sounds.

METHODS21 youth with anterior disc displacement were included as experimental group, and 26 symptomless youth were included as control group. The joint vibrations during rhythmic maximal open-close jaw movement of all subjects were recorded. The sensitivity and specificity of total integral in diagnosis of reducible anterior disc displacement were calculated.

RESULTSAll TMJ vibration parameters, include total integral, integral < 300 Hz, integral > 300 Hz, > 300/< 300 Hz radio, peak amplitude, peak frequency and median frequency, were significantly higher in experimental group than that in control group (P < 0.05). Along with the increasing of disc displacement degree, the TMJ vibration parameters were increasing, and total integral significantly increased (P < 0.05). The total integral demonstrated a high sensitivity and specificity in diagnosis of anterior disc displacement with reduction (0.86 and 0.85, respectively).

CONCLUSIONThe TMJ vibration parameters are significantly higher in youth with reducible anterior disc displacement than that in symptomless youth. Different pathological stages of disc displacement show different TMJ sounds.

ObjectiveTo investigate the quality of life (QOL) of the epilepsy patients and the factors affected the QOL.Methods200 cases were investigated using the Quality of Life in Epilepsy Inventory 10 (QOLEI-10) and the Washington Psychosocial Seizure Investigate (WPSI). 200 healthy persons were chosen as normal control group. ResultsThe QOL of the patient group were significantly poor as compared with that of normal control group(P<0.01). The factors that the patients always faced with were disability in the attack control, short in money, unemployment, restriction of movement, disability in intercommunication, psychological disorder (depress, strain, anxiety, dread, shame feel, cognitional dysfunction, etc.), as well as the difficult to get professional curtains, taking medicine improperly and side effects of the medicine. Conclusions The factors mentioned, which were usually neglected by many doctors, do affect the QOL of epilepsy patients, and hinder the epilepsy treatment effectively.

OBJECTIVE To investigate the effect of phosphotyrosine interaction domain containing 1 (PID1, NYGGF4) onpromotion of IR and HCC, and explore its underlying mechanisms. METHODS Lentivirus were used to mediate the knockdown of PID1 in HFD induced IR mouse model as well as ob/ob mice. Intraperitoneal glucose and insulin tolerance were performed 4 weeks after lentivirus injection. Hydrodynamics-based transfection was applied to induce the liver specific overexpression of PID1. Flow cytometry was exerted to detect the proportion and function of immune cells.qRT-PCR and Western blot were used to detect the expression of downstream pathways of PID1. Liquid chromatography-mass spectrometry (LC-MS) and co-immunoprecipitation (Co-IP) were conducted to identify proteins interacting with PID1.Chromatin immunoprecipitation(ChIP)was operated to measure the modification of H3K4me3 of PID1 promoter.RESULTS PID1 restriction improved insulin resistance,hyperglycemia and fatty liver. Conversely, hepatic knockdown of PID1 attenuated liver xenografted tumor growth. Moreover,PID1 liver-specific protooncogenes via hydrodynamics-based transfection established a primary hepatocellular carcinoma mouse model,induced an immunosuppressive environment,with the reduction of CD3+,CD4+,CD8+T cells,retarded maturation of dendritic cells(DCs),pronounced differentiation of regulatory T cells(Tregs),and recruitment of MDSC.In addition,PID1 overexpression activated prolifer-ation related genes, promoted anti-inflammatory genes, suppressed pro-inflammatory genes, induced glycolysis and lipid metabolism genes to facilitate tumorigenesis in liver. Importantly, PID1 exerted its tumor-promoting function through binding to epidermal growth factor receptor(EGFR)and activation of downstream KRAS/ERK pathway.As such,PID1 exist trimethylation of histone H3 at lysine 4(H3K4me3) modification and IR up-regulated the expression of PID1 by activation the H3K4me3 modification. CONCLUSION PID1 is a new gene that exerts both liver cancer-promoting and insulin resistance inducing function.IR accelerates liver cancer development and progression partially dependent on the activation of PID1.
