? Diabetic retinopathy is one of those significant complications of diabetes.With the increasing number of diabetic patients, blind caused by diabetic retinopathy is a serious threat to human health which cannot be neglected, but there is no highly effective treatment for it. Consequently, early detection and preventive treatment for it are important.Currently, studies have found that urine microalbumin had a close relation with diabetic retinopathy and that urine microalbumin might play an important role in early predicting of diabetic retinopathy. The review is about the diagnostic significance of urine microalbumin test for early diabetic retinopathy.

BACKGROUND:Increasing evidence suggests that Sanguis draxonis is of great significance for treating pressure sores, burns and ulcers.
OBJECTIVE:To observe the influences of Sanguis draxonis on vascular endothelial growth factor, epidermal growth factor, substance P and hydroxyproline in rats undergoing tissue-engineered skin transplantation and to verify its promotion of wound repair.
METHODS:The tissue-engineered skin transplantation model of rats were established. Rats in treatment groups were given external application, single oral use of 0.1 g/(kg·d) Sanguis draxonis and combined use, respectively. No treatment was given in control group. After continuous treatment for 7 days, the expression levels of vascular endothelial growth factor, epidermal growth factor, substance P and hydroxyproline in skin tissue were determined.
RESULTS AND CONCLUSION:Compared with the control group, the levels of vascular endothelial growth factor, epidermal growth factor, and hydroxyproline were significantly increased (P<0.05 or P<0.01), while substance P had no change in the treatment groups (P>0.05). These results demonstrate that Sanguis draxonis can promote tissue-engineered skin to repair skin wound by upregulating the expression levels of vascular endothelial growth factor, epidermal growth factor, and hydroxyproline.

Objective:To investigate the root canal anatomy of one-rooted mandibular second molars. Methods:The root canals of 18 one-rooted mandibular second molars were visualized on radiographs and clinical examination, some specimens were cut at the mid-root level and observations were made on the coronal root section. Teeth with C-shaped canal system were categorized by using a modification of Melton classification.Results:12 molars exhibited C-shaped canals.2 molars were classified as category Ⅰ,5 as Ⅱ and another 5 cases as Ⅲ.Conclusions:C-shaped canals in mandibular second molars vary in canal number and shape.

Objective To observe the effect of acupuncturing Lianquan point combined with rehabilitation on severe pseudobulbar palsy.Methods Sixty patients with severe pseudobulbar palsy were divided into the control group and therapy group with 30 cases in each group. The patients of the control group were treated with medication, nasal feeding and vein nutrition. The patients of the therapy group were added with acupuncturing Lianquan point combined with rehabilitation besides methods the control group used. After two periods of treatment, the effects of two groups were compared.Results The overall efficient rate was 96.7% in the therapy group, and 73.3% in the control group, the former was obviously superior to the latter ( P<0.05).Conclusion Acupuncturing Lianquan point combined with rehabilitation can improve the therapeutic effect of severe pseudobulbar palsy.

The DNA fragment RM07 was isolated from halophilic archaea Halobacterium halobium, which can function as promoter not only in halophilic archaea, but also in Escherichia coli as eubacterial promoter. Sequencing analysis indicated that it possessed the typical consensus sequences (-35 and -10) of bacterial gene promoter, which was confirmed by further deletion analysis: With its -35 sequence deleted and -10 sequence left,DNA fragment RM07a nearly cannot initiate transcription;With its both -35 and -10 sequences,RM07b DNA fragment could be active as promoter at a level even higher than RM07. Our research also showed that the promoter function of RM07 fragment in Escherichia coli was under the control of environmental factors,especially its positive correlation with the increasing concentration of sodium chloride. Therefore, RM07 DNA fragment may be potential1 novel promoter source for constructing double-function vectors. It also has special significance in elucidating the issues of the fusing characteristics of archaea and lateral gene transfer between archaea and bacteria.

Objective To explore predictive value of baseline red cell distribution width (RDW) determined in a routine blood count for severity of chronic heart failure (CHF) and mortality during hospitalization.Methods The study group comprised 135 patients hospitalized in the our hospital with CHF in the Ⅱ ～ Ⅳ class according to New York Heart Association (NYHA).The control group included 44 patients in class Ⅰ.Hematological and biochemical parameters were obtained and compared among groups.Receiver operator characteristic (ROC) curves were used for assessing predictive values.Results RDW increased significantly in class Ⅲ and Ⅳ compared to class Ⅰ [(14.3 ±2.3)％ and (14.3 ± 1.7)％ vs (12.9 ±0.8)％,P ＜0.01].Areas under ROCs (AUCs) of RDW,N-terminal prohormone brain natriuretic peptide (NT-proBNP) for class Ⅳ HF was 0.817 and 0.840,respectively.RDW was significantly elevated in mortality group compared to survival group [(15.8 ± 1.8)％ vs (13.7 ± 1.7) ％,P ＜ 0.01],predictive value of RDW was lower than that of NT-proBNP but was comparable to white blood cell (WBC),neutrophil (NEU),lymphocyte (L),and neutrophil/lymphocyte ratio (N/L) for mortality during hospitalization with AUCs (0.837,0.939,0.858,0.891,0.885,and 0.885,respectively).RDW and NT-proBNP showed low predictive values for repeated admission (≥3).RDW was an independent risk factor for mortality (OR =2.531,95％ CI:1.371 ～4.671).Conclusions RDW increased significantly in class Ⅲ and Ⅳ patients and death group.The predictive value of RDW is comparable to NT-proBNP for class Ⅳ and lower than that of NT-proBNP for mortality.Elevated RDW is an independent risk factor for mortality.

Objective: To assess the psychosomatic symptoms in women referred for in vitro fertilization. Methods: The SCL-90 was administered to 100 women referred for IVF (in vitro fertilization and embryo transfer ) and 100 women referred for ICSI (intracytoplasmic sperm injection) at the time of their first presentation to the infertility clinic. The control group comprised of 100 women presenting to gynecology clinics. In addition, socio-demographic information was captured through a structured questionnaire designed for the purpose of this study.Results:The total scores of two study subgroups and control group were 53.8?30.8, 52.5?31.7 and 42.1?32.3 respectively. It was significantly higher score in study groups than that of in control group(F=3.40, P
