Objective To evaluate the results of prosthesis augmentation,relieve suffering patient experience,improve shape and touch of breast.Methods According to design,in dual-plane mammaplasty transaxillary approach with endoscopic assistance,we used soft-tissue expansion before prosthesis,saline volume in expander was the same as prosthesis size at beginning; adjusting expander volume and position,then determined prosthesis size according to expander volume lastly.after intraoperative sustained expansion for 30 to 60 minutes twice prosthes volume,replace expander with prosthesis.Results This method was applied in 120 patients,showing that pain significantly reduced after expansive without use of analgesia pump; complications included that 3 patients appeared seroma and absorbed soon; 2 patients had poor prosthese location,which was adjusted in reoperation; one capsular contracture was repaired later.After 6-months to 2-years follow-up,the results showed that breast was nature and dynamic; satisfactory rate reached to 95 ％.Conclusions In augmentation mammaplastic operation,pre-adoption of an expander can make it easy to adjust the location of prosthesis,to avoid being injured and to determine prosthesis volume by expander injection of saline volume,especially for patient with different size of both breasts.

OBJECTIVETo explore the correlation of the gene polymorphisms of Toll-like receptor 2 ( TLR2) and TLR4 with the susceptibility and recurrence of condyloma acuminatum (CA).

METHODSUsing Snapshot, we detected the gene polymorphisms of TLR2 597(T/C), 1350(T/C), 15607(A/G), and 2258(G/A) and TLR4 896(A/G) and 1196(C/T) in the peripheral blood of 140 CA patients and 105 HPV-negative controls. We made comparisons between the CA patients and controls as well as between the cases of recurrent CA and those of non-recurrence at 6 months after treatment.

RESULTSThere were 72, 48, and 20 cases of genotype TT, TC, and CC of TLR2 597 (T/C), respectively, in the CA patients, as compared with 71, 31, and 3 cases in the controls. The gene frequency of mutant C was 31. 43% in the patients, significantly higher than 17.62% in the controls (χ2 = 12.04, P < 0.01), and it was 38.68% in the recurrent cases, remarkably higher than 27.01% in the non-recurrent cases (χ2 = 4.16, P < 0.05). There were 74, 49, and 17 cases of genotype TT, TC, and CC of TLR2 1350( T/C), respectively, in the CA patients, as compared with 73, 29, and 3 cases in the controls. The gene frequency of mutant C was 29. 64% in the patients, significantly higher than 16. 67% in the controls (χ2 =11.05, P < 0.01), and it was 36.79% in the recurrent cases, markedly higher than 25. 29% in the non-recurrent cases (χ2 = 4.18, P < 0.05). There were 44, 66, and 30 cases of genotype AA, AG, and GG of TLR2 15607(A/G), respectively, in the CA patients, as compared with 26, 58, and 21 cases in the controls. There was no significant difference in the gene frequencies of mutant G between the two groups (χ2 = 0.33, P > 0.05). No mutant genes of TLR2 2508 (G/A) or TLR4 896(A/G) and 1196(C/ T) were detected in either the CA patients or the controls. Linkage disequilibrium analysis showed a tight linkage between TLR2 597 (T/C) and 1350(T/C) (D' = 1, r2 = 0.93).

CONCLUSIONTLR2 597(T/C) is tightly linked to 1350(T/C), which is correlated with both the susceptibility and the recurrence of condyloma acuminatum.

We used metabolomics to investigate the ability of a traditional Mongolian medicine called modified Tabusen-2 (MT-2) to improve kidney yang deficiency (KYD) in rats. All animal experiments were conducted under the guidance and standards of the Medical Ethics Committee of Inner Mongolia Medical University. SD rats were divided into 6 groups of six rats: a normal group, a model group, Jinkuishenqi pill administration group (1.26 g·kg^-1), and MT-2 administration in high-, medium- and low-dose groups (1.512, 0.756, and 0.378 g·kg^-1). KYD was established by intramuscular injection of hydrocortisone (HC) and biochemical indicators and clinical characterization was used to confirm that KYD was established. All groups received intragastrically administered drug (Jinkuishenqi pill or MT-2) or saline. Serum from each group was collected after 8 weeks and analyzed by UPLC-Q-exactive-MS to measure various biochemical indicators. The biomarkers affected by MT-2 were identified and the metabolic pathways of KYD regulated by MT-2 were analyzed by metabolomic analysis. The results show that MT-2 can decrease serum creatinine (Cr) in KYD rats and significantly increase (P<0.05) the content of thyroid stimulating hormone (TSH) and luteinizing hormone (LH). In serum samples, 38 biomarkers such as corticosterone, L-phenylalanine, and DL-tryptophan were measured as possible indicators for disease development in KYD rats. MT-2 lowered 18 biomarkers of KYD, including corticosterone, deoxycorticosterone, and L-phenylalanine, and altered 13 related metabolic pathways including phenylalanine, tyrosine and tryptophan biosynthesis, phenylalanine metabolism and steroid hormone biosynthesis, resulting in an overall improvement in KYD. MT-2 appears to be important in improving KYD in rats mainly by regulating metabolites such as amino acids, steroids and lipids.

Background::Intravertebral and general anesthesia (GA) are two main anesthesia approaches but both have defects. This study was aimed to evaluate the effect of subarachnoid anesthesia combined with propofol target-controlled infusion (TCI) on blood loss and transfusion for total hip arthroplasty (THA) in elderly patients in comparison with combined spinal-epidural anesthesia (CSEA) or GA.Methods::Totally, 240 patients (aged ≥65 years, American Society of Anesthesiologists [ASA] I-III) scheduled for posterior THA were enrolled from September 1st, 2017 to March 1st, 2018. All cases were randomly divided into three groups to receive CSEA (group C, n = 80), GA (group G, n = 80), or subarachnoid anesthesia and propofol TCI (group T, n= 80), respectively. Primary outcomes measured were intra-operative blood loss, autologous and allogeneic blood transfusion, mean arterial pressure at different time points, length of stay in post-anesthesia care unit (PACU), length of hospital stay, and patient satisfaction degree. Furthermore, post-operative pain scores and complications were also observed. The difference of quantitative index between groups were analyzed by one-way analysis of variance, repeated measurement generalized linear model, Student-Newman-Keuls test or rank-sum test, while ratio index was analyzed by Chi-square test or Fisher exact test. Results::Basic characteristics were comparable among the three groups. Intra-operative blood loss in group T (331.53 ± 64.33 mL) and group G (308.03 ± 64.90 mL) were significantly less than group C (455.40 ± 120.48 mL, F = 65.80, P < 0.001). Similarly, the autologous transfusion of group T (130.99 ± 30.36 mL) and group G (124.09 ± 24.34 mL) were also markedly less than group C (178.31 ± 48.68 mL, F= 52.99, P < 0.001). The allogenetic blood transfusion of group C (0 [0, 100.00]) was also significantly larger than group T (0) and group G (0) ( Z = 2.47, P = 0.047). Except for the baseline, there were significant differences in mean arterial blood pressures before operation ( F= 496.84, P < 0.001), 10-min after the beginning of operation ( F = 351.43, P < 0.001), 30-min after the beginning of operation ( F = 559.89, P < 0.001), 50-min after the beginning of operation ( F = 374.74, P < 0.001), and at the end of operation ( F= 26.14, P < 0.001) among the three groups. Length of stay in PACU of group T (9.41 ± 1.19 min) was comparable with group C (8.83 ± 1.26 min), and both were significantly shorter than group G (16.55 ± 3.10 min, F = 352.50, P < 0.001). There were no significant differences among the three groups in terms of length of hospitalization and post-operative visual analog scale scores. Patient satisfaction degree of group T (77/80) was significantly higher than group C (66/80, χ 2= 7.96, P = 0.004) and G (69/80, χ 2 = 5.01, P = 0.025). One patient complained of post-dural puncture headache and two complained of low back pain in group C, while none in group T. Incidence of post-operative nausea and vomiting in group G (10/80) was significantly higher than group T (3/80, χ 2 = 4.10, P = 0.043) and group C (2/80, χ 2 = 5.76, P = 0.016). No deep vein thrombosis or delayed post-operative functional exercise was detected. Conclusions::Single subarachnoid anesthesia combined with propofol TCI seems to perform better than CSEA and GA for posterior THA in elderly patients, with less blood loss and peri-operative transfusion, higher patient satisfaction degree and fewer complications.

Objective To analyze the value of conventional T2WI combining with breath-hold Cartesian VIBE sequence, and compared with Blade combining with breath-free radial VIBE sequences in pre-operative T staging of potentiallly resectable esophageal carcinoma. Methods Sixty-five cases of esophageal carcinoma were concluded prospectively. All patients had received pathological examination of gastroscope biopsy before MRI. Patients received MR examination, including T2WI, breath-hold VIBE, Blade, and breath-free radial VIBE sequences. Two radiologists with more than five years experiences in the diagnosis of chest, performed T staging in MRIby referring to the the 7th edition of UICC-AJCC TNM classification. The results of MRI T staging and the postoperative pathological T staging were analyzed byχ2 test. Results Sixty-five patients were included. Diagnostic coincidence rates of the preoperative T staging by using conventional T2WI combining with breath-hold Cartesian VIBE sequences and Blade combining with breath-free radial VIBE sequences were 51%(33/65) and 88%(57/65) ,with 32 and 8 cases overstaging or understaging respectively, and the statistical differences were significant(χ2=20.80, P<0.05). The former diagnostic accuracy of esophageal carcinoma in situ, muscularis violation and esophageal fiber membrane were 42%(8/19), 54%(14/26), 55%(11/20), and the latter were 89%(17/19), 88%(23/26), and 85%(17/20). Conclusions Diagnostic coincidence rate of the preoperative T staging by using Blade combining with breath-free radial VIBE sequences is much higher than conventional T2WI combining with breath-hold Cartesian VIBE sequences. Blade combining with breath-free radial VIBE sequences could be used as non-invasive imaging method in preoperative T staging of potentially resectable esophageal carcinoma.

Objective To investigate the relationship between polymorphisms of gene promoter region INS 5′UTR single nu-cleotide and type 2 diabetes and serum IAA-Ab levels.Methods By Sequenom MassArray SNP genotyping detection technology, INS 3 pyomter regime single nucleotide polymorphisms (rs689,rs714641 77 and rs3842738)of 497 patients in Chongqing with type 2 diabetes cases(treatment group)and 500 cases(control group)were genotyped and analyzed.IAA-Ab levels in diabetes patients was detected.Theχ2 test statistic was used to analyze the treatment group and control groups.The genotype frequency distribution of IAA-Ab-positive and negative groups SNP was analyzed by non-conditional logistic regression,adjusted for sex,age impact,cal-culated the odds ratio (OR)and 95 % confidence interval(CI ).The polymorphic loci with type 2 diabetes susceptibility and serum GAD-Ab levels was evaluated.Results The genotype frequency distribution of rs689AA,TT and AT was 58.75%,28.77% and 12.47%,respectively.The control group are 50.40%,35.60% and 14.00% respectively.The difference was statistically significant (χ2 =3.923,P <0.05).Compared with the genotype of AA,TT genotype can decrease risky of diabetes,with OR values 0.35(95%CI :0.18-1.06).There was significant difference of AA,TT,AT genotypes between IAA-Ab negative and IAA-Ab positive pa-tients (P < 0.05 ).Conclusion INS polymorphisms might be related to the risky of type 2 diabetes and serum IAA-Ab level in chinses population.

Objective To predict the incidence of birth defects in Xi'an using the auto-regressive integrated moving average product seasonal model.Methods In Xi'an,the trend of the incidence of birth defects was analyzed and tested from October 2009 to August 2015.Using the data from September to December 2015,the actual birth defects were compared with the model fitting data to evaluate the predictive performance of the model.Multiple seasonal ARIMA model was then fitted under time series to predict the incidence of birth defects in 2016.Results Seasonal effect was seen in the incidence of birth defects in Xi'an.A multiple seasonal ARIMA(0,0,1) (0,1,1)12 was established.The mean of absolute error and the relative error were 9.5 and 0.084,respectively,when compared to the simulated number of patients from September to December in 2015,suggesting that ARIMA (0,0,1) (0,1,1)12 has a better predictive ability.Results under the prediction of multiple seasonal ARIMA model showed that the number of patients in 2016 was similar to that of 2015 in Xi'an,with a slight increase and a decrease in the peak value.Conclusion Multiple seasonal ARIMA(0,0,1)(0,1,1)12 model could be used to successfully predict the incidence of birth defects in Xi'an.

OBJECTIVETo study the regulatory effect of Bushenfang on the serum testosterone (T) level of naturally aging rats and its mechanism, in order to provide a theoretical and experimental basis for the clinical treatment of late onset hypogonadism (LOH) in males.

METHODSThirty-two 18-month-old male SD rats were randomly divided into four groups of equal number, naturally aging model and low-, medium- and high-dose Bushenfang groups, and another eight 4-month-old rats were taken as normal controls. The rats of the aging model and normal control groups were treated with normal saline, while those of the low-, medium- and high-dose Bushenfang groups received intragastrically Bushenfang at 3.25, 7.50 and 15.00 g/kg, respectively, all for 3 weeks. Then the rats were sacrificed, the histomorphologic changes of the testis observed by HE staining, the serum T level measured by radioimmunoassay, and the expressions of the StAR protein, P450scc and 3beta-HSD I determined by RT-PCR.

RESULTSThe number of Leydig cells was obviously increased after Bushenfang treatment. The levels of serum T were significantly higher in the low-, medium- and high-dose Bushenfang groups ([6.74 +/- 1.56] nmol/L, [8.50 +/- 1.99] nmol/L and [12.41 +/- 2.91] nmol/L) than in the model group ([3.48 +/- 0.75] nmol/L) (P < 0.05). The three Bushenfang groups also showed a remarkable elevation in the mRNA expressions of StAR (0.74 +/- 0.29, 0.83 +/- 0.32 and 1.35 +/- 0.50), P450scc (0.72 +/- 0.36, 1.023 +/- 0.30 and 1.41 +/- 0.37) and 3beta-HSD I (0.58 +/- 0.14, 0.72 +/- 0.07 and 0.85 +/- 0.18), as compared with the models (StAR: 0.44 +/- 0.09; P450scc: 0.33 +/- 0.05; 3beta-HSD I: 0.34 +/- 0.02), with significant differences in the StAR expression between the high-dose Bushenfang and the model groups, as well as in P450scc and 3beta-HSD I expressions between the medium- and high-dose Bushenfang and the model groups (P < 0.05).

CONCLUSIONBushenfang could improve the pathological status of testicular injury and increase the expression of testosterone synthetase, which might be the mechanism behind its regulatory effect on the serum T level of aging rats.

Design space approach is applied in this study to enhance the robustness of first ethanol precipitation process of Codonopsis Radix (Dangshen) by optimizing parameters. Total flavonoid recovery, dry matter removal, and pigment removal were defined as the process critical quality attributes (CQAs). Plackett-Burman designed experiments were carried out to find the critical process parameters (CPPs). Dry matter content of concentrated extract (DMCE), mass ratio of ethanol to concentrated extract (E/C ratio) and concentration of ethanol (CEA) were identified as the CPPs. Box-Behnken designed experiments were performed to establish the quantitative models between CPPs and CQAs. Probability based design space was obtained and verified using Monte-Carlo simulation method. According to the verification results, the robustness of first ethanol precipitation process of Dangshen can be guaranteed by operating within the design space parameters. Recommended normal operation space are as follows: dry matter content of concentrated extract of 45.0% - 48.0%, E/C ratio of 2.48-2.80 g x g(-1), and the concentration of ethanol of 92.0% - 92.7%.

OBJECTIVETo recognize the importance of analyzing the result of immunohistochemical staining correctly.

METHODReview of the three misdiagnosed cases lymphoma and exploring the causes of misdiagnosis through reviewing their clinics, histopathology and immunohistochemistry.

RESULTSCase 1 of lymphocyte rich classical Hodgkin's lymphoma (LRCHL) was misdiagnosed as follicular lymphoma (FL) initially, the RS cells were overlooked morphologically and wrongly determined BCL-2 and CD20-positive cells as tumor cells immunohistochemically; also once misdiagnosed as nodular lymphocyte predominant Hodgkin's lymphoma (NLPHL) because the CD20-negative RS misjudged cells as the positives. Case 2 of AML tumor cells expressed TdT, CD7 and CD43 unspecifically, which misdiagnosed as T-cell lymphoblastic lymphoma (T-LBL). Case 3 of type B1 thymoma was misdiagnosed as T-LBL, because CK wasn't expressed satisfactorily resulting in neglecting neoplastic epithelial cells, and lymphocytes in the background were TdT and CD99-positive.

CONCLUSIONThe diagnosis of lymphoma should be based on morphology, immunohistochemistry, clinics, and genetics. Moreover, the correct judgment of immunohistochemical staining is essential to make right diagnosis.
