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.

Objective To evaluate the remote effect of local injection of botulinum toxin by use of the F-wave measures. Methods The F-wave responses as well as M-waves were recorded before injection, and at 1 week,12 to 24 weeks after local injection of botulinum toxin type-A (BTX-A) in 26 patients, including 19 with hemi-facial spasm (HFS),5 Meige syndrome and 2 torticollis spasmodicus (TS).The following parameters were analyzed: M-wave latency (ML) and amplitude (Mamp), F-wave minimal latency(Fmin) and average latency(Fave),amplitude (Famp), duration (Fdur), persistence (Fper) and chronodispersion (Fchr). The above parameters were obtained through the electric stimulation of ulnar and tibial nerves, and recorded from the abductor digiti minimi and extensor digitorum brevis, respectively. Results No definite F-wave was obtained by electric stimulation of ulnar nerve at 1 week after injection in 3 HFS patients (5 nerves). The Fave recorded from electric stimulation of ulnar and tibial nerves prolonged significantlyand Fdur from ulnar nerve increased significantly at 1 week after injection, but were not significantly different from those of pre-injection when recorded at 12 to 24 weeks after injection. No significant correlation of the altered F-wave parameters was found with the dosage of BTX-A. Conclusion Fdur and Fave could sensitively assess the remote effect of the local injection of BTX-A, the remote effect might be correlated with the distance between injected muscle and tested muscle, rather than the dosage of BTX-A.

Objective To report the clinical features a nd pathologic findings of 1 case of mixed epithelial and stromal tumor of the ki dney. Methods The patient who had a 20-year history of taking oral contraceptive was a 50-year-old woman with pain in left flank asso ciated with hematuria for half a year.CT and MRI revealed an 8 cm?6 cm cystic a nd solid mass located in the upper pole of the left kidney.A diagnosis of cystic renal carcinoma was made before operation.Radical left nephrectomy was performe d in July 2004. Results The upper pole of the left kidne y was found severely adhesive with peripheral tissues du- ring operation.Gro ssly,the tumor exhibited a 7.9 cm?8.9 cm?9.0 cm multilocular cyst full of coff ee- colored mucoid fluid with varying size ranging from 0.5 to 2.0 cm.Focall y thick-walled cysts with solid areas were seen.Microscopic findings showed the tumor was composed of a mixture of stromal elements formed by spindle cells and epithelial elements that were variable in cell types including cuboidal,columna r and hobnail cells.Differentiation of gastrointestinal tract was found in epith elial elements.Thick-walled blood vessels and distinctive bands of smooth muscl e cells were present in the stromal elements.Immunohistochemical staining reveal ed that the epithelial component was positive for AE1/AE3,and stromal component was positive for ER,PR,and SMA.No specific treatment was given and the patient w as free of signs of recurrence 8 months after operation. Conclusions Mixed epithelial and stromal tumor of the kidney is recognized to b e a kind of benign neoplasm.Differentiation of gastrointestinal tract in epithel ial elements is rare.It should be distinguished from any other benign and malign ant tumors in the kidney.
