OBJECTIVE:To observe the clinical efficacy of Hepatocyte growth-promoting factors(PHGF) combined with Wuji baifeng pills for liver cirrhosis. METHODS:A total of 97 patients with liver cirrhosis were randomly assigned to either control group(n=32,conventional therapy) or treatment group(n=65,PHGF plus Wuji baifeng pills in addition to routine treatment).The course of treatment was 3 months for both groups. Clinical data including cardinal symptoms and signs,hepatic function,blood clotting function,hepatic fibrosis parameters,the inner-diameter of the portal vein and splenic vein(PVD,SVD),spleen thickness(SPT) measured by the color Doppler ultrasonography were monitored before and after treatment. RESULTS:After treatment,the symptoms and signs of the treatment group had better improvement than in the control group,with a markedly higher total effective rate than in the control group(84.62% vs.59.38%,P

Background Sclera remodeling process in axial elongation is one of the main pathological mechanisms of axial myopia progression.Studies confirmed that transforming growth factor-β1(TGF-β1) participates in the sclera remodeling process,and Smad3 is one of TGF-β1 downstream signal gene transcriptive factors,so to explore its role in sclera remodeling process of myopic eyes is of great significance for pathogenesis and prevention research of myopia.Objective This study was to investigate the expressions of type Ⅰ collagen and Smad3,a TGF-31 downstream target,in sclera of form deprivation myopic (FDM) eyes and explore the impact of TGF-β1-Smad3-type Ⅰ collagen signaling pathway on collagen remodeling in myopic sclera.Methods Seventy-five 1-week-old guinea pigs were randomly divided into normal control group (25 guinea pigs) and FDM group (50 guinea pigs).Monocular FDM was induced by occluding the left eyes of guinea pigs in FDM group with translucent latex balloons for 2,4,6 weeks,respectively,and consecutive occluding for 4 weeks followed by uncovering for 1 week (4/-1 weeks).The refractive power was detected by retinoscopy and axial length was measured with A-type ultrasound.Immunohistochemistry and reverse transcription-PCR were employed to detect the dynamic expressions of type Ⅰ collagen and Smad3 protein ad mRNA in the sclera of guinea pigs with emmetropia and experimental myopia,ard the relationship between collagen Ⅰ and Smad3 levels was analyzed.Results The refraction was hypermetropic in both normal control group and FDM group before occluding of eyes (P＞0.05),and the hypermetropic power was gradually reduced over time in the normal control group.In the FDM group,the refractive power was gradually changed from (+2.09 ± 0.31)D before occluding to (-1.23±0.69),(-4.17±0.59),(-7.07±0.56) and (-4.30±0.58)D,and the axial length was increased from (5.93-±0.39)mm to (6.62±0.36),(7.30±0.34),(7.99--0.32),and (7.21 ±0.36) mm at weeks 2,4,6,and 4/-1 after occluding,respectively,indicating significant differences in refractive power and axial length over time in the FDM group from normal control group and self-control group (all at P＜0.05).The expressions of Smad3 and type Ⅰ collagen protein and mRNA in the sclera of the FDM group was significantly lower than those of the control group and self-control group in various time points (all at P＜0.05).The positive correlation were found in the expression of Smad3 on the myopic sclera with that of type Ⅰ collagen in both protein and mRNA levels (protein:r=0.993,P＜0.05;mRNA:r=0.954,P＜0.05).Conclusions The myopic power and ocular axis increase dependent upon occluding time,and the expressions of Smad3 and type Ⅰ collagen in the sclera are correspondingly weakened in FDM eyes.A consistent expression trend is found between Smad3 and type Ⅰ collage,suggesting Smad3 and type Ⅰ collagen participate in the regulation of sclera remodeling in myopia by TGF-β1-Smad3-Collagen Ⅰ signaling pathway.

Six DNA extraction methods and four DNA purification methods were compared and analyzed in this study to get higher quality DNA from the rhizospheric soil of Fritillaria thunbergii Miq.Results showed that higher purity DNA were harvested by pretreating the soil with 20 mmol/L EDTA(pH 7.5),then isolating soil DNA with CTAB-SDS-frozen-thawing,and further purified by agarose method.The recovery rate of this soil DNA was about 44.00 ?g/g ? 2.65 ?g/g soil,and they were qualified for the microbial diversity analysis in the rhizospheric soil of F.thunbergii Miq based on the 16S rDNA sequence.

Objective:To investigate the value of high-resolution 3T MRI in the detection of triangular fibrocartilage complex (TFCC) injuries through a diagnostic test.Methods:A retrospective case series analysis was performed in 133 patients with ulnar wrist pain admitted in Beijing Jishuitan Hospital from January 2013 to April 2018. There were 68 males and 65 females, aged 14-69 years (mean 32.6 years). The patients was examined with the wrist MRI with consistent parameters and then received wrist arthroscopic detection or treatment. The TFCC injuries were classified as central injury, namely triangular fibrocartilage disc injury and peripheral injury, namely the tear of ulnar attachment, radial attachment, distal radioulnar ligaments and ulnocarpal ligaments. Take the results of wrist arthroscopy as the gold standard, the MRI and arthroscopic findings were compared and the sensitivity, specificity, positive/negative predictive value and positive/negative likelihood ratio were determined.Results:Wrist arthroscopy confirmed TFCC injuries in 122 patients, among which 72 patients were with central injury and 102 with peripheral injury. Meanwhile, TFCC injuries were diagnosed with MRI in 124 patients, among which 75 patients were central injury and 111 cases were peripheral injury. As for central injury, the sensitivity/specificity, positive/negative predictive value and positive/negative likelihood ratio of MRI were 0.972/0.918, 0.933/0.966 and 11.85/0.03, respectively; when the target pathology was peripheral injury, the sensitivity/specificity, positive/negative predictive value and positive/negative likelihood ratio of MRI were 0.882/0.323, 0.811/0.45 and 1.30/0.37, respectively.Conclusions:High-resolution 3T MRI is accurate in detection of central injury of TFCC, no matter the injury is traumatic or degenerated. In the diagnosis of peripheral injury of the TFCC, MRI can provide some help for its high sensitivity. However, the positive findings of MRI on peripheral structures should be cautious because of the poor specificity, and hence the results of history, physical examination and MRI should be considered together to attain an accurate diagnosis.

Objective To establish the imatinib (STI-571)-resistant subline in vitro and investigate its biological characteristics. Methods Human glioblastoma multiform drug-resistant cell line (named U251AR) was established in vitro by successively increasing the concentration of imatinib in a cell culture medium. The 50％ inhibitory dose (IC50) values and the resistance indexes ([IC50U251/STI-571]/[IC50 U251]) for other chemotherapeutic agents were evaluated using cell counting kit-8 assays. Expressions of acquired multidrug resistance P-glycoprotein (MDR 1, ABCB 1; MDR3, ABCB4),breast cancer resistance protein (BCRP, ABCG2) and multidrug resistance-associated protein 1 (MRP1,ABCC1) were detected by QRT-PCR. Flow cytometry was employed to detect the protein expression of ABCG2. Results The U251AR was developed after culture for 12 months and similar morphologies of U251 and U251/STI-571 cells were determined. The resistance coefficient of U251AR cells to imatinib was 20.41 times more than that of the parent cells, and U251AR cells showed cross-resistance to many anti-tumor agents (P＜0.05). The resistance coefficients of U251AR cell line to doxorubicin and cisplatin were 5.06 and 10.28 times, respectively, more than those of U251 cells (P＜0.05). QRT-PCR indicated that the mRNA levels of MDR1, MRP1, BCRPandABCB4 (P-g4) in the U251/STI571 resistant cells were significantly higher than those in the U251 cells (P＜0.05). The protein expression of ABCG2 in U251AR cell line was significantly increased as compared with that in the parent cells (P＜0.05).Conclusion We have successfully established multidrug resistant cell line U251AR, and the drug resistance of U251/STI571 is associated with over-expressions of ABCC1, ABCB1, ABCB4, and ABCG2 mRNA, and ABCG2 protein.

OBJECTIVETo explore the specific efficacy of different moxibustion techniques in treatment of common diseases and clinical indications, and compare the specificity in clinical indications and efficacy among different moxibustion techniques so as to guide clinical practice better.

METHODSThe modern computerization and data mining technology were adopted to set up moxibustion literature database. The relevant literature of moxibustion techniques in recent 60 years were collected, screened, examined, extracted and analyzed statistically so as to explore the advantages of different moxibustion techniques in clinical treatment.

RESULTS(1) Of 2,516 literature, moxa stick, moxe cone and moxa device were used in the highest frequency in internal medicine department, for 730 times, 278 times and 102 times respectively. The warm needling technique was used in the highest frequency, for 70 times in the surgical department. (2) In the dermatology department, the curative rate with moxa cone was the highest, 75%. In the ear-nose-throat department, the warm needing technique and moxa device achieved the highest curative rate, 49% for both of them. In the internal medicine department and surgical department, the curative rate of warm needling technique was 53% and 58% respectively. In the gynecology department, the curative rate of moxa device was the highest, 59%. In the pediatrics department, the curative rate of moxa cone was the highest, 80%. (3) The numbers of priority disorders, frequency ≥20 times: 24 kinds of disease for moxa stick, five kinds of disease for moxa cone, 2 kinds of disease for warm needling technqiue and one disorder for moxa device. Facial paralysis, diarrhea, lumbar and leg pain and elbow and knee swelling pain were of the highest priority, treated with these 4 moxibustion techniques, with a certain of literature research values. (4) The warm needling technique achieved the better efficacy on elbow and knee swelling pain, lumbar and leg pain and diarrhea compared with the other three techniques and the curative rate was higher. The moxa device tecnique achieved the higher curative rate for facial paralysis compared with the other three techniques.

CONCLUSIONThrough the comparison of application frequency, curative rate, clinical application frequency in disorders and the efficacy of priority disorders in the treatment with different moxibustion techniques, it is found that moxa stick, moxa cone and moxa device are simple in manipulation, safe and effective. Hence, they can be extensively used in the treatment of common disorders in every department in clinic. The warm needling technique acts on the body by the co-work of needling and warming stimulation of mugwort. It achieves the particular effect on the disorders with complicated etiologies compared with the other three techniques. It can be chosen in priority for the disorders caused by blockage in meridian and collateral and stagnation of qi and blood.

Piloerection is an involuntary erection of body hairs that usually has physiological correlates such as cold or a strong emotional experience. Piloerection may also be a rare manifestation of seizure.Here, we report a case of 54-year-old man who experienced pilomotor seizures from temporal lobe epilepsy. The patient presented with sudden piloerection and no loss of consciousness many times a day. Magnetic resonance imagingof the brain showed threelesions in the right hemisphere, with the largest lesion in the right temporal lobe. A video-EEG showed an ictal discharge in the delta range with right temporal onset. Digital subtraction angiography excluded arteriovenous malformation. The lesion in the right temporal lobe was resected. Immunohistochemistry confirmed a cerebral cavernous malformation. There was no further seizure. A review of the published literature revealed that ictal piloerection as a lone manifestation is rare. Most cases of pilomotor seizure originate in the temporal lobe. Close to four fifth of the cases has a structural lesion. EEG was able to confirm the diagnosis of ictal piloerection in the majority of cases.

OBJECTIVETo study the influence of cow's milk protein allergy (CMPA) on the diagnosis of functional gastrointestinal diseases (FGID) based on the Rome IV standard in infants and young children.

METHODSA total of 84 children aged 1 month to 3 years who were diagnosed with CMPA were enrolled as the case group, and 84 infants and young children who underwent physical examination and had no CMPA were enrolled as the control group. The pediatricians specializing in gastroenterology asked parents using a questionnaire for the diagnosis of FGID based on the Rome IV standard to assess clinical symptoms and to diagnose FGID.

RESULTSThe case group had a significantly higher incidence rate of a family history of allergies than the control group (P<0.05). In the case group, 38 (45%) met the Rome IV standard for the diagnosis of FGID, while in the control group, 13 (15%) met this standard (P<0.05). According to the Rome IV standard for FGID, the case group had significantly higher diagnostic rates of reflex, functional diarrhea, difficult defecation, and functional constipation than the control group (P<0.05). The children who were diagnosed with FIGD in the control group were given conventional treatment, and those in the case group were asked to avoid the intake of cow's milk protein in addition to the conventional treatment. After 3 months of treatment, the case group had a significantly higher response rate to the treatment than the control group (P<0.05).

CONCLUSIONSIn infants and young children, CMPA has great influence on the diagnosis of FGID based on the Rome IV standard. The possibility of CMPA should be considered during the diagnosis of FGID.
