Objective To study the current situation of diagnosis and treatment of rudimentary uterine horn pregnancy through 4-cases report. Methods We made a clinical study of 4 cases of rudimentary uterine horn pregnancy admitted to our hospital between 1995 and 2005. Results Three patients had been undergone artificial abortion before they were admitted to our hospital. All the patients were asymptomatic. Ultrasonography was made in 3 cases. Two cases were diagnosed as rudimentary uterine horn pregnancy. Three patients were cured with surgery. Conclusions Rudimentary uterine horn pregnancy is rare and with atypical clinical manifestation in the first trimester. Although diagnosis before surgery is difficult, ultrasonography and MRI make a great role. Surgery is the most important therapeutic method.

Knowledge-attitude-practice model is widely used in the self-management of type-2 diabetes.Through proper education,patients can gain diabetic knowledge as well as positive attitude on glucose control.By regulating diet,exercise,self glucose monitoring and medication compliance,diabetic patients are able to control blood glucose more effectively,and have less complications and higher quality of life.Researches on the application and effectiveness of various diabetic knowledge,attitude and self-management behavior scales are reviewed in this article.

Objective To evaluate the results and toxic effects in three dimensional radiotherapy (3DCRT)with late course accelerated hyper-fractionation for advanced esophageal carcinoma.Methods From December 2001 to December 2003,115 patients were randomly divided into two groups:in 3DCRT group,55 patients were given late course accelerated hyper-fractionation radiotherapy to a total close of 66 Gy (2.0 Gy per fraction,5 times per week;to a dose of 36 Gy were changed into 1.5 Gy/f,2 f/d).In CF group,60 patients were given late course accelerated hyper-fractionation radiotherapy to a total dose of 66 Gy.Results The 1-, 2-,3-,4-year survival rates in 3DCRT group were 63.6 %, 50.9 %, 38.2 %, 30.9 % compared to 58.3 %, 38.3 %,33.3 %,23.3 % in CF group(X~2=4.44,P=0.031),and local control rates in 1-,2-,3-,and 4- years in 3DCRT group were 72.7 %,58.1%,47.2 % and 36.3 %,compared to 53.3 %,40 %,28.3 %,and 20 %(X~2=5.33,P=0.013)in CF group.However,in the 3DCRT group,the incidence of acute esophagitis was similar to CF group; hematogenous toxic and acute bronchitis were similar between the two groups. Late course lung injury in CF group was higher than that in 3DCRT group.Conclusion 3DCRT is able to improve the local control rate and survival rate,and unable to improve acute and late radiation toxie effects.

Objective:To investigate the predictive value of serum thyroid hormone in the short-term prognosis of patients with septic shock..Methods:The 133 patients with septic shock admitted to Intensive Care Unit (ICU) of Nanjing Hospital of Nanjing Medical University were enrolled. Data of patient’s general clinical information, acute physiology and chronic health evaluationⅡ (APACHE Ⅱ), serum triiodothyronine ( T3 ), thyroxine (T4), free triiodothyronine (FT3) , free thyroxine (FT4) and thyroid stimulating hormone(TSH) in 24 h were collected, and the ratio of T3 to FT3 (T3/FT3) was calculated. The patients were divided into the survival group and death group according to the prognosis during ICU hospitalization. Univariate and multivariate analyses were used to analyze the prognostic factors of patients with septic shock. The receiver operating characteristic (ROC) curve and Kaplan-Meier analysis were plotted to evaluate the diagnostic efficacy of serum thyroid hormone for the short-term prognosis of patients with septic shock.Results:Compared to the survival group, FT3, T3 and T3/FT3 were significantly lower in the death group [1.73 (1.54, 2.52) vs. 1.32 (0.94, 1.54) pmol/L, 0.70 (0.56, 0.79) vs. 0.33 (0.25, 0.43) nmol/L, 318.18(299.44, 448.05) vs. 250.00 (192.31, 313.92), respectively; all P < 0.05 ]. The levels of serum T3 and FT3 were significantly correlated with the APACHEⅡ score in patients with septic shock (FT3: r = -0.25, P= 0.004; T3: r = - 0.24, P= 0.006). Binary Logistic regression analysis showed that FT3, T3 and T3/FT3 were independent risk factors of the short-term prognosis of patients with septic shock [FT3: OR = 6.533, 95% CI: 0.687 - 62.157, P = 0.012; T3: OR = 0.529, 95% CI: 0.372 - 0.975, P= 0.000; T3/FT3: OR = 1.719, 95% CI: 1.007 - 1.931, P= 0.002]. ROC curve analysis showed that FT3, T3 and T3/FT3 all had certain predictive value for the short-term prognosis of patients with septic shock, and the diagnostic value of T3 was the largest [AUC = 0.874, 95% CI: 0.794-0.954, P= 0.000]. The Kaplan-Meier curve showed a significantly higher survival rate in patients with T3 greater than 0.535 nmol/L than patients with T3 less than 0.535 nmol/L. Conclusions:The serum levels of thyroid hormone T3 and FT3 are closely related to the severity of septic shock. T3 is an effective ICU mortality during hospitalization prognostic indicator for patients with septic shock, which is better than FT3 and T3/FT3.

Objective:To investigate the predictive value of different glycemic variability indexes within 6 hours on the short-term prognosis of septic shock patients.Methods:A retrospective study was conducted. The 133 patients with septic shock admitted to intensive care unit (ICU) of Nanjing Hospital Affiliated to Nanjing Medical University from December 2014 to December 2019 were enrolled. Patients with septic shock admitted to ICU died during hospitalization were enrolled in the death group and others in the survival group. General data of the patients including gender, age, underlying disease, site of infection, duration of mechanical ventilation, length of ICU stay, whether to use continuous renal replacement therapy (CRRT) and acute physiology and chronic health evaluationⅡ (APACHEⅡ) scores within 24 hours were collected. The blood glucose (GLUadm), mean arterial pressure (MAP), serum creatinine (SCr) and procalcitonin (PCT) were recorded at ICU admission. The patients admitted to ICU received bundle therapy within 6 hours and blood glucose was observed every 2 hours. The blood glucose difference (GLUdif), average blood glucose (GLUave), blood glucose standard deviation (GLUsd) and blood glucose variation coefficient (GLUcv) within 6 hours were calculated. Multivariate Logistic regression analysis was used to analyze the prognostic factors of short-term prognosis of patients with septic shock, and receiver operating characteristic (ROC) curve was plotted to evaluate the diagnostic efficacy of glycemic parameters for short-term prognosis of septic shock patients.Results:A total of 133 patients with septic shock were admitted to ICU, among them 87 patients survived and 46 patients died during the ICU hospitalization. Compared with the survival group, the SCr at ICU admission and APACHEⅡ score within 24 hours were significantly higher in the death group [SCr (μmol/L): 208.5 (143.0, 286.5) vs. 172.0 (91.0, 234.0), APACHEⅡ score: 30.28±6.67 vs. 24.03±5.90, both P < 0.05], the length of ICU stay was shorter [days: 4.00 (2.00, 10.25) vs. 9.00 (4.00, 13.00), P < 0.01]. However, there were no significant differences in the baseline data of gender, age, underlying disease, infection site, CRRT ratio, MAP or PCT at ICU admission between the two groups. Compared with the survival group, the GLUsd and GLUcv within 6 hours in the death group were higher [GLUsd (mmol/L): 2.33 (1.95, 3.14) vs. 2.02 (1.66, 2.52), GLUcv: (31.00±7.06)% vs. (23.31±10.51)%, both P < 0.05]. There were no statistically significant differences in the levels of GLUadm, GLUdif or GLUave within 6 hours between the two groups. Multivariate Logistic regression analysis showed that APACHEⅡ score within 24 hours and GLUsd and GLUcv within 6 hours were independent risk factors of the short-term prognosis of septic shock patients [APACHEⅡ score: odds ratio ( OR) = 1.173, 95% confidence interval (95% CI) was 1.095-1.256, P = 0.000; GLUsd: OR = 1.465, 95% CI was 1.038-2.067, P = 0.030; GLUcv: OR = 1.089, 95% CI was 1.043-1.138, P = 0.000]. ROC curve analysis showed that GLUsd and GLUcv within 6 hours both had certain predictive value for the short-term prognosis of septic shock patients, the area under ROC curve (AUC) of GLUcv within 6 hours was higher than that of APACHEⅡ score (0.765 vs. 0.753), and AUC of GLUsd within 6 hours was close to APACHEⅡ score (0.629 vs. 0.753); and the diagnostic value of GLUsd combined with GLUcv within 6 hours was higher than the two respectively (AUC: 0.809 vs. 0.629, 0.765), the sensitivity was 97.8%, and the specificity was 66.7%. Conclusion:GLUsd combined with GLUcv within 6 hours can be used to estimate the short-term prognosis of septic shock patients.

Traditional herbal medicines, Panax ginseng, Panax quinquefolium and Panax notoginseng, attract our attention for their extensive and powerful pharmacological activities. Ginsenosides are the main active constituents of these medicinal herbs. The related glycosyltransferases involved in ginsenoside biosynthesis are the key enzymes which catalyze the last important step. Modification of ginsenoside aglycones by glycosyltransferases produces the complexity and diversity of ginsenosides, which have more extensive pharmacological activity. At present, ginsenoside aglycones and compound K have been obtained by synthetic biology. As the last step of ginsenoside biosynthesis, glycosylation of ginsenoside aglycones has been studied intensively in recent years. This review summarizes the basic strategies and research advances in studies on glycosyltransferases involved in ginsenoside biosynthesis, which is expected to lay the theoretical foundation for the in-depth research of biosynthetic pathway of ginsenosides and their production by synthetic biology.

The expression of specific genes in sex chromosomes is the basis of sex-specific membrane protein in mammalian spermatozoa. The gene expression products are shared among spermatozoa through intercellular bridges, however, the phenomena of male transmission-ratio distortion and sex ratio distortion proved that differential proteins exist between X and Y spermatozoa. In addition, the existence of sex-specific proteins was confirmed by the separation experiment of X/Y chromosome bearing spermatozoa and the detection result of sex specific proteins. At the same time, it was also confirmed that the difference of the sex-specific protein is weak . The advance of separation techniques as well as the integration and optimization among these techniques has made it possible to separate sex-specific membrane proteins in mammalian spermatozoa.

The degQ gene, amplified from Bacillus subtilis by PCR, was cloned to pUBS (sucrose induced secretion vector). After transformed into DB403, recombination named DB403(pUBSD) was formed. The results of the fermentation showed that degQ gene enhanced the expression of B. subtilis fibrin enzyme. The activity of the enzyme was increased to 2.2 times as the original one. In this article, the effects of different conditions, such as different kinds of sugar, different concentration of sucrose and different induced time were also be investigated and compared.

Objective To investigate the early clinical outcome of peripheral cutting balloon(PCB) in the management of peripheral vessel stenosis.Methods Thirteen patients with peripheral limb vessel stenosis, in which 4 stenoses in hemodialysis access and 9 at lower limb arteries,underwent angioplasty by PCB.For multiple stenosis in the same vessel,the distal one should be expanded firstly.The balloon pressure was controlled in the range of 8 atm to 10 atm(1 atm=10.108 kPa).All the patient were given continuous anticoagulant therapy after the procedure.Results All the procedure were carried out successfully on the 13 patients,and no serious complications occured.The symptoms did not recur in all patients after the procedure.The 5 months' follow-up angiography proved that no restenosis occurred in one patient with previous stenosis at the hemodialysis access.Conclusion The angioplasty with PCB was a safe and reliable procedure in management of the peripheral limb vessel stenosis.The early outcome is satisfying.
