Objective To observe the clinical efficacy of modified Huanglian Wendan Decoction for treatment of tic disorder (TD) children with syndrome of wind stirring due to phlegm-heat; To detect its effects on peripheral-blood miR-429 expression. Methods Eighty cases of TD children were randomly divided into treatment group and control group,with 40 cases in each group.In the treatment group,children were treated with modified Huanglian Wendan Decoction, one dosage a day, twice a day, orally. In the control group, TD children were treated with haloperidol, 0.03 mg/(kg?d), orally, according to the symptom to adjust dose, and the maximum amount did not exceed 0.08 mg/(kg?d). 30 d was a treatment course for both groups. The treatment lasted for three courses. Before and after 3 months of clinical observation, the severity of disease was evaluated by TCM syndrome and Yale Global Tic Severity Scale (YGTSS) score. Clinical efficacy and TCM syndrome efficacy were evaluated; the level of miR-429 in peripheral blood was detected; the adverse reactions were observed. Results The total effective rate of clinical efficacy was 82.5% (33/40) in treatment group and 80.0% (32/40) in the control group, without statistical significance (P>0.05); The total effective rate of TCM syndrome efficacy was 92.5% (37/40) in treatment group and 75.0% (30/40) in the control group, with statistical significance (P<0.05). Compared with before treatment, the YGTSS score and TCM syndrome score significantly decreased after treatment (P<0.01), and the TCM syndrome score in the treatment group was much lower than the control group after treatment (P<0.05). Compared with before treatment, miR-429 level in both groups increased obviously after treatment (P<0.01), and the miR-429 level in the treatment group was much higher than the control group after treatment (P<0.05). There were mild constipation (1 cases), diarrhea (2 cases), and anorexia (2 cases) in the treatment group, and obvious lethargy (3 cases) and dizziness (3 cases) in the control group. Conclusion Modified Huanglian Wendan Decoction shows obvious effects for treating TD, and can up-regulate miR-429 of peripheral-blood.

Objective To analyze the characteristics and epidemic trend of malignant tumor in Yueqing City of Zhejiang Province from 2012 to 2015 so as to provide scientific bases for policy making regarding control and prevention of malignant tumor.Methods Descriptive epidemiological analyses were made on the data of malignant tumor in Yueqing City from 2012 to 2015.Results The average annual incidence rate of malignant tumor from 2012 to 2015 was 248.85/105, the incidence rates from 2012 to 2015 were 238.24/105, 242.95/105, 247.15/105, 266.85/105, respectively.The average male incidence rate was 265.82/105, the average female incidence rate was 230.38/105.The former was higher than the latter.The group of 40-year-old and above age accounted for 91.64% of the total number of malignant tumor cases.Leukemia was common among 20-year-old and below age group.Breast cancer, liver cancer and lung cancer were common among 20-to 39-year-old age group.Lung cancer, liver cancer and gastric cancer were common among the age group of 40-year-old and above.The top five incidence rates of malignant tumor were lung cancer, liver cancer, gastric cancer, colorectal cancer and breast cancer, accounting for 56.74% of total cases thereof.Conclusion From 2012 to 2015, the incidence trend of malignant tumor in Yueqing City remained basically stable;the incidence rate remained relatively high and showed a slow rising trend on a yearly basis with the incidence rate of lung cancer increasing most significantly.The male incidence rate of malignant tumor was obviously higher than the female incident rate thereof.For the age group over 40, the incidence rate of malignant tumor increased significantly.It is necessary to pertinently strengthen the relevant health education of malignant tumor and implement the relevant early monitoring, thereby reducing the incidence rate.

BACKGROUNDSubjective olfactory tests are easy to perform and popularly applied in the clinic, but using only these, it is difficult to diagnose all disorders of the olfactory system. The olfactory event related potentials technique offers further insight into the olfactory system and is an ideal objective test. This analysis was of subjective and objective data on the olfactory function of twelve patients with loss of smell associated with an upper respiratory infection (URI).

METHODSWe tested the twelve patients with URI induced olfactory loss by medical history, physical examination of the head and neck, olfactory tests and medical imaging. Olfactory function was assessed by Toyota and Takagi olfactometry including olfactory detection and recognition thresholds and olfactory event-related potentials (OERPs) recorded with OEP-98C Olfactometer.

RESULTSAn unusual phenomenon was observed in five patients in whom the subjective detection and recognition thresholds were normal, while the expected OERPs were not detectable.

CONCLUSIONSWe suggest that the discordance between olfactory psychophysical measurements and OERPs might be the results of abnormal electrophysiology related with olfactory neuropathy caused by viral URI. In addition, the measurement of OERPs might play a significant role in evaluating olfactory dysfunction.

Objective The use of tourniquets in total knee arthroplasty has been controversial. Many studies have focused only on the different time courses and neglected the effects of pressures. Currently,there is no study explaining the mechanism of tourniquet-induced injury. The aim of this study was to explore the effects of different tourniquet pressures on pain and swelling after total knee arthroplasty and to explore the mechanism of injury. Methods Ninety-six patients who underwent total knee arthroplasty at Nanjing General Hospital from June 2017 to December 2017 were randomly as-signed to 240 mmHg group (low pressure),270 mmHg group (medi- um pressure),and 300 mmHg group (high pressure). The patient's pain and thigh circumference were measured before and 1-2 days after surgery. Blood samples were taken before and 3,8,and 24 hours after surgery. Superoxide dismutase 1 (SOD1),prostaglandin E2 (PGE2) and myoglobin were detected,analysed and compared. Results In the perspective of the pain and swelling of affected limb after surgery,the 300 mmHg group (73.24±10.51) was significantly different from the 240 mmHg group (58.18±9.66) and the 270mmHg group (63.06±10.06). In the perspective of the SOD1 level in serum,the 300mmHg group (97.77±13.82) was significant-ly different from the 240mmHg group (63.72±15.02) and the 270 mmHg group (70.58±5.85) at 3h after surgery,and then the diver-gence was gradually decreased. In the perspective of the PGE2 level in serum,the 300 mmHg group (478.05±35.80) was significantly different from the 240mmHg group (334.42±33.12) and the 270mmHg group (391.85±19.41) at 3h after surgery,and the divergence was started to decrease after 8 h. In the perspective of the myoglobin level in serum,the 300 mmHg group (30.43±9.79) was also sig-nificantly different from the 240 mmHg group (17.58±1.93) and the 270 mmHg group (22.28±4.21) at 8 h after operation,the diver-gence was started to decrease after 24 h. which began to decrease after 24 h. Correlation analysis showed that there was a significant cor-relation between pain (correlation coefficient 0.518,P<0.001),swelling (correlation coefficient 0.345,P<0.05) and stress after sur-gery. Conclusion The pain and swelling of the affected limb is positively correlated with the pressure of the tourniquet during the operation. Muscle necrosis is the main mechanism of the injury. Oxidative stress occurs in the ischemic phase and inflammation occurs in the reperfusion phase.

OBJECTIVETo establish criteria for AIS of Lenke5 and Lenke6 by an anterior only procedure of the lower curve fusion.

METHODSA retrospective study was conducted between March 1999 and May 2004 to investigate 52 AIS patients of Lenke5 and Lenke6. All the patients were observed 24 years (34 months on average). Many parameters were evaluated. At final assessment, two groups emerged: Group A had satisfactory results (the thoracic curve was reduced) and Group B had just the opposite.

RESULTSPreoperative thoracic curve in group A averaged 33 degrees and 18 degrees after surgery. The lumbar curve averaged 49 degrees before surgery and 21 degrees after surgery. In group B (n = 6), the average thoracic curve was 38 degrees before surgery and 45 degrees after surgery, whereas the lumbar curve averaged 46 degrees before surgery and 25 degrees after surgery. Two of these patients underwent posterior thoracic instrumentation and fusion because of the unreasonable balance.

CONCLUSIONSA successful surgical outcome was dependent on both the flexibility of the thoracic curve and the patients' maturity. The thoracolumbar/lumbar-thoracic (TL/L:T) Cobb ratio in combination with the flexibility of the thoracic curve were the best predictors among the structural indexes.

This study aimed to analyze the clinical phenotype of chromosome 9p deletion or duplication and its relationship with karyotype. A patient, female, aged 6 months, visited the hospital due to motor developmental delay. Karyotype analysis identified abnormalities of chromosome 9 short arm, and high-throughput sequencing found 9p24.3-9p23 deletion and 9p23-9p13.1 duplication. Her parents had a normal karyotype. Karyotype analysis combined with high-throughput sequencing is of great significance for improving the efficiency of etiological diagnosis in children with motor developmental delay or multiple congenital deformities and mental retardation.

This study was aimed to investigate the expression of Na(+)/H(+) exchanger 1 (NHE1) in K562 and HL-60 cells undergoing DNA damage induced by etoposide and to elucidate the regulating mechanism. Real-time quantitative PCR (RQ-PCR) and Western blot methods were used to determine the expression of NHE1 in K562 cells after the treating with etoposide. Meanwhile, the flow cytometry was used to detect the apoptosis of leukemic cells. The luciferase reporter vector containing NHE1 promoter was constructed to measure relative luciferase activity after treating with different etoposide concentrations. The results showed that the mRNA and protein of NHE1 increased in accordance with apoptosis ratio in HL-60 cells after treated with etoposide (p < 0.05), but no such obvious increase in K562 cells. Treatment with NHE1 specific inhibitor could block etoposide induced alkalization and reduce the apoptosis ratio of HL-60 cells. The expression pattern and apoptosis alteration was not similar in K562 cells. Relative luciferase activity of reporter vector containing NHE1 promoter however increased in K562 cells after treated with etoposide. It is concluded that the expression of NHE1 is up-regulated in the process of apoptosis of HL-60 cells induced by etoposide and depends on the pHi increasing caused by NHE1 up-regulation which is not found in K562 cells although the transcriptional activity increased.

OBJECTIVE To investigate the effects of LW-AFC, a new formula derived from Liuwei Dihuang decoction, on gut microbiota and the behavior of learning and memory of SAMP8 mice, a mouse model of Alzheimer Disease (AD), and identify the specific intestinal microbiota correlating with cognitive ability. METHODS Morris-water maze test, novel object recognition test and shuttle-box test were conducted to observe the ability of learning and memory. 16S rRNA amplicon sequencing (Illumina, San Diego, CA, USA) was employed to investigate gut microbiota. RESULTS The treatment of LW- AFC improved cognitive impairments of SAMP8 mice, including spatial learning and memory ability, active avoidance response, and object recognition memory capability. Our data indicated that there were significantly 8 increased and 12 decreased operational taxonomic units (OTUs) in the gut microbiota of SAMP8 mice compared with senescence accelerated mouse resistant 1 (SAMR1) strains, the control of SAMP8 mice. The treatment of LW- AFC altered 22 (16 increased and 6 decreased) OTUs in SAMP8 mice and among them, 15 OTUs could be reversed by LW-AFC treatment resulting in a microbial composition similar to that of SAMR1 mice. We further showed that there were 7 (3 negative and 4 positive correlation) OTUs significantly correlated with all the three types of cognitive abilities, at the order level, including Bacteroidales, Clostridiales, Desulfovibrionales, CW040, and two unclassified orders. LW-AFC had influences on bacterial taxa correlated with the abilities of learning and memory in SAMP8 mice and restored them to SAMR1 mice. CONCLUSION The effects of LW-AFC on improving cognitive impairments of SAMP8 mice might be via modulating intestinal microbiome and LW-AFC could be used as a potential anti-AD agent.

OBJECTIVETo explore the associations between the single nucleotide polymorphism of human mismatch repair gene hMLH1 and the papillary thyroid carcinoma (PTC) in Chinese Han people.

METHODSA hospital based 1:1 matched case-control study was carried out. The single nucleotide polymorphism (-93G > A, 1151T > A and 655A > G) for 204 pairs of cases with PTC as well as healthy controls was identified by PCR-RFLP, PCR-ASO and DNA sequencing.

RESULTSWith univariate analysis, we found that compared to 1151TT genotype, the TA genotype could increase the PTC risk marginally, with odds ratio (OR) of 2.15 (95%CI: 0.99 - 4.85); While the mutant genotype TA + AA could increase the PTC risk statistically significant, with OR of 2.15(95%CI: 1.02 - 4.69). With 2 x 4 cross-over study, we found that compared to -93GG and 1151TT genotypes, individuals with both -93GA + AA and 1151TA + AA could increase the PTC risk marginally, with OR of 2.50 (95%CI: 0.96 - 6.67); While, compared to 655AA and 1151TT genotypes, individuals with both 655AA and 1151TA + AA could increase the PTC risk statistically significant, with OR of 2.50 (95%CI: 1.02 - 4.73). Multivariate and conditional logistic regression analysis showed the genotype of 1151TA, the history of receiving CT diagnosis, the history of tumor, the negative life events and eating seafood frequently could increase the risk of PTC, with OR of 6.79 (95%CI: 3.18 - 14.49), 3.35 (95%CI: 1.93 - 5.80), 39.03 (95%CI: 3.70 - 41.60) and 3.98 (95%CI: 1.81 - 8.73); While, eating fruit frequently could decrease the PTC risk.

CONCLUSIONThe 1151TA + AA genotype, the history of receiving CT diagnosis, the history of tumor, the negative life events and eating seafood frequently were the risk factors of PTC, while eating fruit frequently was the protective factor.
