Objective To compare and analyze the different clinical features between male and female patients with rheumatoid arthritis (RA), by detecting the gender difference to make clinical decisions. Method The clinical features of 95 male RA patients(MRA) were analyzed and compared with those of 248 female RA patients (FRA) by retrospective analysis method. Results The mean onset age of MRA [18-79 (51.40±15.55) years old] was older than that of FRA[18-75(43.54 ±15.46) years old](P=0.0002). The morning stiffness time of MRA [(1.58 ±1.34) h] was shorter than that of FRA [(2.10 ±1.51) h](P = 0.0357). There was statistical difference in the first involved joint between MRA and FRA (P=0.0170), the prevalence of knee,metatarsonphalangeal joint,shoulder and ankle of MRA was higher than those of FRA, ' but conversely the wrist prevalence of FRA was higher than that of MRA.The prevalence of secondary Sj(o)gren syndrome of MRA(13.68%, 13/95) was rather lower than that of FRA(35.08%, 87/248)(P = 0.0007). MRA had lower positive rate of ANA (2.11% ,2/95) and lower value of IgM [(1.42 ±0.75) g/L] than FRA [(10.48% ,26/248), (1.69 ±0.86) g/L] (P < 0.05). There was no statistical difference between MRA and FRA in articular radiographic changes, most extraarticular manifestations and lab results (P >0.05). Conclusions MRA patients have older onset age and milder articular symptom than FRA patients. The disease severity of MRA is similar to that of FRA. Weighted joints are more involved in MRA. FRA is more inclined to have secondary Sj(o)gren syndrome.

Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease. The prevalence of NAFLD is increasing year by year in the world, which seriously threaten the public health. The pathogenesis of NAFLD is complex, and there is no specific treatment for NAFLD. Natural-derived compounds have the characteristics of multi-target and multi-mechanism, which can improve the curative effect and reduce the toxic and side effects by regulating multiple factors of the disease. They are ideal drugs for treating complex diseases and have unique advantages in improving NAFLD. However, low intestinal absorption, poor bioavailability, and single medicine efficiency limit the utilization of many compounds, and further drug development and clinical application are challenging. This paper reviews the research progress of natural-derived compounds in the prevention and treatment of NAFLD in recent years, analyzes the existing problems, and discusses the improvement strategies, so as to provide reference for related research.

Objective To investigate the hypothesis that food allergy in infants may be associated with variation in their intestinal microflora. The formation of intestinal microflora in healthy infants and changes in food allergic infants were detected.Methods 16S rRNA gene sequences specific for bifidobacterium, lactobacillus and escherichia coli in fecal were quantitatively detected by real-time PCR. The three fecal floras were assessed in 71 healthy infants and 100 infants with food allergy. Results After birth,there were bifidobacteria colonized in infantile intestine,then the number increased rapidly up to 5 times at the sixth month, which was always the preponderant flora. Lactobacilli was also presented in infantile intestine 1 month after birth and augment gradually. The number of Escherichia coli was less than bifidobacteria and lactobacilli and appeared to decline during the early infants. The number of bifidobacteria and lactobacilli in the infants with food allergy were markedly less than that in the healthy infants, but escherichia coli was significantly more than that in the healthy infants.Conclusions During the first year of life,the intestinal microflora in infants is in a developing process. Compared with the healthy infants,bifidobacteria and lactobacilli decrease, but escherichia coli increase in the food allergic infants.These results indicate that the probiotics may be benefit to the prevention and treatment of food allergy.

Objective To analyse the effects of serum estradiol levels during controlled ovarian hyperstimulation (COH) on the outcomes of in vitro fertilization and embryo transfer (IVF-ET). Methods The clinical data of 472 patients undergoing IVF-ET with GnRH analogues recombinant FSH long protocol were retrospectively analysed. The area under the curve (AUC) of estradiol (E2) level was calculated during COH, and patients were categorized into groups according to the percentile of AUC of E2(AUCE2) during COH. The general characteristics and parameters related to the outcomes of IVF-ET were compared among groups. Results The 10th percentile and 90th percentile of AUCE2 were 3 347.0 pmoL/L and 14 414.3 pmol/L, respectively. Four hundred and seventy-two patients were divided into lower reaction group (AUCE2 3 347.0 pmol/L, n=48), normal reaction group (14 414.3 pmol/L>AUCE2 > 3 347.0 pmol/L, n=376) and higher reaction group (AUCE2≥14 413.3 pmol/L, n=48). There was no significant difference in age, body mass index, baseline follicle stimulating hormone level, time of treatment with gonadotropin, endometrium thickness on day of transfer and embryos transferred(P>0.05). Compared with lower reaction group and normal reaction group, the number of oocytes per retrieval and number of embryos frozen were significantly larger(P<0.01) and the mild/severe ovarian hyperstimulation syndrome rate was significantly higher in higher reaction group(P<0.05). There was no significant difference in fertilization rate, cumulative embryo score, high-grade embryo rate, clinical pregnancy rate and implantation rate among groups (P> 0.05). Conclusion Sustained snpraphysiological serum E2 levels during the COH process do not adversely affect the quality of oocytes and embryos, clinical pregnancy rate and implantation rate to some extent in IVF-ET.

Purpose To study the prevalence and feature of EGR gene rearrangement in prostatic carcinoma. Methods 242 consecu-tive core biopsies of prostatic carcinoma were evaluated. All biopsy specimens contained 6-14 cores from left and right sides separately delivered. The patient age ranged 58 to 91 years, and PSA value 5 ng/ml to more than 5 000 ng/ml. Immunohistochemistry ( IHC) for ERG protein overexpression and fluorescent in situ hybridization ( FISH) for ERG gene rearrangement were performed. Results 42 cases were detected positive for ERG by IHC ( positive rate 17. 4%) , and positive for ERG rearrangement by FISH either, with 19 ca-ses showing fusion through deletion and 23 through insertion, while no negative cases by IHC demonstrated positive by FISH. 5 cases revealed positive and negative staining in different carcinoma foci of ERG. No ERG positive staining and rearrangement were found in adjacent benign glands. Of positive cases, 12 cases were graded as Gleason score 6, 23 Gleason score 7, and 7 Gleason score 8 or more. Positive rate was 19. 6% in the group of PSA value less than 100 ng/ml, and 10% of more than 100 ng/ml, whereas 17. 2% in the group of clinical T3 stage or less, and 19% of clinical T4 and lymph node or remote metastasis. ERG rearrangement was associated with lower Gleason score, but not with PSA value, clinical stage and progression using theχ2 test analysis. Conclusions IHC is relia-ble for detection ERG rearrangement and helpful for interpretation of prostatic carcinoma. Multiple foci are common in prostatic carcino-ma. There is no significance between ERG rearrangement and disease prognosis.

Purpose To study clinicopathologic feature of prostate cancer by complete embedding of radical prostatectomy specimen. Methods 108 cases of radical prostatectomy by systematic whole organ embedding were reviewed. Results The patient age ranged from 55 to 80 years ( mean 68. 1 years) . The preoperative average PSA value was 18. 3μg/ml. 59 cases ( accounting for 54. 6% of all prostatectomy cases) were in pT2 stage, while 23. 7% (14/59) in pT2a stage, 8. 5% (5/59) in pT2b, and 67. 8% (40/59) in pT2c. 49 cases (45. 4%)in pT3 stage, while 59. 2% (29/49) in pT3a, 40. 8% (20/49) in pT3b. 3. 6%(3/84)cases presented pelvic lymph node metastasis. 8. 3% (9/108) cases were graded as Gleason Score 6 or less, 61. 1% Gleason Score 7, 30. 6%(33/108)Gleason Score 8 or more. Gleason Pattern 5 component was found in 26. 9% (29/108) cases. Positive margin was observed in 25. 9% (28/108) cases, with 75% (21/28) in pT3 stage and 53. 6% (15/28) having Gleason Pattern 5. Patient in pT2 stage pres-ented mean PSA value of 14. 00 μg/ml, involved in no more than 2 biopsy cores in 68. 5% cases, and more than 5 cores in 4. 3%, while in pT3 stage, presented mean PSA value of 23. 82μg/ml, involved in no more than 2 cores in 19. 6%, and more than 5 cores in 28. 3%. The difference of involved core number was significant in pT2 and pT3 tumors ( P<0. 01 ) . 81. 3% cases graded Gleason Score 6 in biopsy was assigned to Gleason Score 7 or more in prostatectomy. Conclusions Completely sampling radical prostatectomy specimen should be recommended for accurate staging and margin status. Preoperative PSA value, Gleason Score of biopsy, involved core number by cancer is a still helpful parameter for clinical staging and risk estimate.
