Fever and sweating are the most common clinical symptoms, which are important parts in the inquiry of traditional Chinese medicine (TCM). Just as Zhang Jingyue said, Firstly inquire for cold and heat and secondly in-quire for the sweating. It placed both symptoms as priorities in the collection of disease history. In the clinical prac-tice, febrile diseases refer to acute exogenous diseases infected by warm evil with the main symptom of fever. And fever is almost throughout the entire process of febrile diseases. It is also known as Han-Bing for the visible varia-tion of sweating in its entire disease process. It is important to identify the abnormality of sweating for the determina-tion of the severity febrile diseases and the level of body fluid shortage. Therefore, two main symptoms for the diag-nosis of febrile diseases are particularly prominent and important. The reasons of sweating and fever in febrile dis-eases have been explored so much but the relationship between them is less which is extremely essential to learn more about febrile diseases. So we are expected to explore this topic to make better use of theories of febrile dis-eases.

Objective To observe the results and reality of transurethral resection of bladder tumor(TUR-Bt) with upside down loop and plsamakinetic in the prevention of obturator nerve reflex.Methods A total of 211 patients with lumbar anesthesia received TUR-Bt.Firstly,the tumor tower above bladder wall was cut with the traditional way.When intraoperative findings were obturator nerve reflex,or to the obturator nerve mapping area,operation should be changed to superimpulse plasma column electrode vaporization to cut off residual tumor tissue,then after flipping the loop,the residual tumour was resected with upside-down loop from the tumour side wall.Results In 211 cases,192 cases had a little obturator nerve reflex,but the movement of body was not obvious,which did not influence the operation.The serious complication,such as perforation of bladder and injury of nerve and vessel,did not occur.Conclusions The lateral resection of bladder side wall tumour with upside-down loop can effectively avoid strong obturator nerve reflex,which is safe,uncomplicated,and efficacious and it does not increase the additional outlay and hurt.

Objective To discuss the effect of the interval between neoadjuvant therapy and surgery on downstaging for local advanced rectal cancer.Method s From May 2003 to December 2008 as earlier period,32 patients with clinical stage T3 or T4 rectal cancer received neoadjuvant therapy followed by surgery after 4 -6 weeks.From January 2009 to December 2010 as later period,21 patients with clinical stage T3 or T4 rectal cancer received neoadjuvant therapy followed by surgery after 8 weeks.Dworak classification,TNM stage and clinical outcome after surgery were compared between two group paitents.Results All patients with local advanced rectal cancer received R0 resection.No surgical complications and mortality were observed in all cases.Pathological results showed that 0 and 2 cases were Dworak classification Ⅳ,5 cases were Dworak classification Ⅲ,3 and 6 cases were Dworak classification Ⅱ and 24 and 8 cases were Dworak classification Ⅰ in earlier period and later period,respectively (x2 = 9.109,P = 0.028).The postoperative staging showed that 6 and 13 cases were ypT1N0M0,22 and 6 cases were ypT2N0M0,1 case was ypT3 N0M0,3 and 1 cases were ypT3N1 M0,respectively (x2 = 10.909,P = 0.012).There were 65.6% or 81.0% cases reserved anus in earlier period and later period,respectively(x2 = 1.468,P = 0.226).Conclusions The neoadjuvant therapy followed by surgery after 8 weeks is associated with a more significant downstaging effect for local advanced rectal cancer.However,the effect of an extended interval between neoadjuvant therapy and surgery on clinical outcome still needs further investigation.

Objective To explore the clinical and imaging factors influencing the patients' prognosis after preoperative radiotherapy for local advanced rectal cancer.Methods We retrospectively analyzed 106 locally advanced rectal cancer patients from June 2004 to September 2015 in our institution.All patients underwent preoperative radiotherapy.According to the Mandard score,patients were divided into 5 groups (TRG1-5).All patients were divided into two groups according to the TRG,which including good responder (TRG1 + 2) and poor responder (TRG3 + 4 + 5) groups.All of the tumor ADC values of post-RT were measured by Diffusion-weighted MRI technology,and the relationship between tumor ADC values of post-RT and TRG was analyzed.Results In univariate analysis,age,chemotherapy,pT,pN,differentiation degree,vascular invasion and TRG were significantly associated with overall survival (x2 =3.945-8.110,P ＜ 0.05).Multivariate analysis indicated that differentiation degree and TRG were the independent prognostic factors for OS (x2 =5.221,6.563,P ＜ 0.05).No significant difference was found between long-course and short-course radiotherapy group (P ＞ 0.05) in OS.The good responder group had a favorable survival in 5-year OS compared to the poor responder group (x2 =8.110,P ＜ 0.05).Preoperative radiotherapy,preoperative chemotherapy,pathological type,differentiation degree and gross type,vascular tumor thrombus and tumor ADC values of post-RT were significantly associated with TRG (x2 =4.189-18.139,P ＜ 0.05).The best critical point of tumor ADC values of post-RT was 1.7 x 10-3 mm2/s by using ROC curve.The accuracy of tumor ADC values of post-RT in predicting TRG1 + 2 was 70％.Conclusions The TRG can predict the efficacy of preoperative radiotherapy in patients with locally advanced rectal cancer based on the Mandard score.There was no significant difference in OS between long-course radiotherapy group and short-course radiotherapy group.The tumor ADC values of post-RT might become a potential factor to predict TRG in patients with locally advanced rectal cancer after preoperative radiotherapy.

The objective of this research was to explore whether the number of CD34(+)CD38(+) cells infused affects hematopoietic reconstitution after cord blood transplantation. The number of CD34(+)CD38(+) cells in cord blood was analysed with flow cytometry after freezethawing. The body weight and time for neutrophil and platelet recovery were measured in 20 children with acute leukemia. The results showed that the median number of CD34(+)CD38(+) cells infused was 29.47 (9.85 - 325.71) x 10(4)/kg. A median time for neutrophil recovery (> 5 x 10(8)/L) in 20 patients was 18.5 (11 - 32) days, and time for platlet recovery (> 2 x 10(10)/L) in 19 of 20 patients was 45 (12 - 118) days. The number of CD34(+)CD38(+) cells infused correlated with time to neutrophil and platelet recovery (r = -0.577, P < 0.01 and r = 0.503, P < 0.05, respectively). In conclusion, the number of CD34(+)CD38(+) cells infused is correlated with the time for hematologic recovery.

OBJECTIVESeveral studies have shown that L-selectin on CD34-positive cells play a role in hematopoietic reconstitution after peripheral blood stem cell transplantation and allograft bone marrow transplantation. This study sought to investigate whether the numbers of CD(34)(+)CD(62L)(+) cells infused affect the engraftment of hematopoietic stem cells (HSC) and the time to neutrophil and platelet recovery after unrelated umbilical cord blood transplantation for the treatment of childhood acute leukemia.

METHODSTwenty-three children with acute leukemia who received unrelated umbilical cord blood transplantation of mostly mismatched HLA locus were included in this study. Flow cytometry was used to count the numbers of CD(34)(+)CD(62L)(+) cells after freezing-thawing by labelling the cells with anti-CD(34) and anti-CD62L. The patients' clinical data including body weight, engraftment of the HSC, times to neutrophil and platelet recovery were evaluated.

RESULTSTwenty-one patients who received CD(34)(+)CD(62L)(+) cell infusion at a number ranging from 1.37 x 10(5)/kg to 2.68 x 10(6)/kg (median, 3.567 x 10(5)/kg) had successful engraftment of the unrelated umbilical HSC. The numbers of CD(34)(+)CD(62L)(+) cells infused were statistically different between patients who had successful engraftment of the umbilical HSC and those who had not (P < 0.05). The engraftment occurred more commonly in patients who received > 1.3 x 10(5) CD(34)(+)CD(62L)(+) cells/kg. The time of neutrophil recovery (> 500/ microl) ranged from 11 days to 32 days (median, 17.5 days). The data of the time to platelet recovery (> 2 x 10(5)/ microl) were obtained in 18 patients, and it ranged from 12 days to 118 days (median, 14 days). There seemed to be a tendency of correlation between the numbers of CD(34)(+)CD(62L)(+) cells infused and time to platelet recovery (gamma = -0.324, 0.05 < P < 0.1), whereas the numbers of CD(34)(+)CD(62L)(+) cells infused correlated with the time to platelet recovery (gamma = -0.470, P < 0.05).

CONCLUSIONThis study suggests that the numbers of CD(34)(+)CD(62L)(+) cells infused might be involved in the engraftment of HSC and hematologic reconstitution after umbilical cord blood transplantation.

OBJECTIVETo investigate the expression of cyclin-dependent kinase inhibitor p27kip1 in renal cell carcinoma and its clinical significance.

METHODSThe expressions of p27kip1 mRNA and protein were evaluated using reverse transcription polymerase chain reaction (RT-PCR), Western blotting and immunohistochemistry with tissue chip technique in renal cell carcinoma (RCC) tissues, adjacent tissues and 786-0 cell line. The relationship between the expression of p27kip1 and the tumor size, the clinical stage, pathological type and stage were evaluated, and the results by the 3 methods were analyzed to evaluate the relationship between the mRNA and protein of p27kip1.

RESULTSThe expression of p27kip1 protein (detected by immunohistochemistry and Western blotting) in RCC tissue was significantly lower than that in the adjacent normal tissues (P<0.05). The expression of p27kip1 mRNA (by RT-PCR) showed no significant difference between the two groups. p27kip1 protein expression was found to be inversely correlated to the tumor grade and clinical stage (P<0.05). Western blotting and immunohistochemistry showed a high coincidence rate in the detection of P27kip1 protein expression in RCC samples (P<0.001, K=0.828).

CONCLUSIONp27kip1 mRNA expression shows no difference between RCC and normal tissues, while the protein expression is significantly lower in the cancer tissues, suggesting a regulatory mechanism of p27kip1 expression at the transcriptional level. Low expression of p27kip1 protein may promote the development and progression of RCC. p27kip1 protein may serve as a diagnostic and prognostic marker of RCC.

Flow cytometry was previously applied for analysis of Rh(D) antigen density, therefore it was suggested that the flow cytometry may be used for routine detection of weak D positive phenotypes. This study was purposed to evaluate its practicability. Six weak D positive and 7 DEL individuals were detected by using saline, IAT and absorption/elution test from 2010 to 2011 years. By RHD genotyping, zygosity analysis and sequencing, 3 cases of weak D type 15, 3 cases of partial D type DVI-III and 7 cases of DEL carrying RHD1227A alleles were identified. Taking 2 normal Rh(D)-positive and 2 D-negative samples as controls, all the samples were tested by using flow cytometry, and the median fluorescence intensities were observed as well. The results indicated that all weak D type 15 and partial D type DVI samples were detected to be positive by flow cytometry, as compared with 2 Rh(D)-negative samples (P < 0.05). Seven 7 DEL samples were tested to be negative (P > 0.05), although one of 7 DEL was tested as "±" in IAT and strong positive in absorption/elution. The RHD zygosity analysis showed this DEL individual as RHD(+)/RHD(+) homozygote. It is concluded that the sensitivity of detecting D antigen by flow cytometry is similar to that of IAT, but lower than absorption/elution test. As for detecting weak D or partial D antigens, IAT is easier than flow cytometry; as for identifying DEL, the flow cytometry is not sensitive enough.

OBJECTIVETo understand the occupational hazards of ammonium perchlorate dust on operating workers and to provide the basis preventive measures for protecting the workers' health.

METHODS36 workers exposed to ammonium perchlorate dust and 48 unexposed workers from one factory were selected as the exposure and control groups. Investigations on the general condition, sampling of dust in the workplaces and a special medical examination were conducted for two groups, including occupational history, clinical manifestations, blood routine test, hepatic and renal functions, indexes of thyroid hormone, spirometric test and chest X-ray.

RESULTSThe total dust concentration of AP in the batch plant reached to 51.63 ± 43.27 mg/m(3), exceeding the U.S. Occupational Safety and Health Administration (OSHA) permission exposure limits. The systolic blood pressure in the exposure group was higher than that of the control group (146.14 ± 21.03 VS 134.67 ± 18.58), and the difference was statistically significant (P < 0.05). The detection rates of the cumulative total symptoms, short of breath and skin itch symptoms in the exposure group were significantly higher than those in the control group (86.11% VS 66.67%; 30.56% VS 12.50%) (P < 0.05), respectively. FT(3) level in the exposure group significantly lowered than the control group, and the difference was statistically significant (P < 0.01); The pulmonary function result showed that FEV1/FVC% in the exposure group was lower than that in the control group (106.50 ± 28.99 VS 111.70 ± 19.72), but the difference was not significant. X-ray examination revealed one case of pulmonary X-ray abnormalities in the exposure group, diagnosis of pneumoconiosis, and one case with about 1.0 × 1.0 small nodules detected on the left of lung door area in the control group.

CONCLUSIONSThe systolic blood pressure of workers in the exposure group was significantly higher, which could not exclude related to the exposure to AP dust; The T(3) levels in the exposure workers were lower than those in the control group, which may due to AP exposure, suggesting that long-term chronic exposure to AP dust may affect thyroid function.
