Objective: To investigate six mineral element contents of rice bran and milled rice from three color rice cultivars (white rice, red rice, black rice). Methods: Select 36 typical cultivars and determine Se, Zn, Fe, Ca, Mn, Cu contents in their rice bran and milled rice with AFS-2201 atomic fluorescent spectrometer and AA-680 atomic absorption spectrometer. Results: 1. The six mineral element contents of rice bran were 2.58, 3.35, 10.04, 4.58, 12.79 and 6.59 times as those of milled rice respectively. 2. The Ca content of black milled rice was significantly higher than that of white and red milled rice. The Mn content in rice bran of white rice was significantly higher than those of black and red rice. Other mineral element contents were not significantly different. 3. For rice bran and milled rice of different cultivars, the contents of each mineral element in three color rices varied greatly. Conclusions: 1. The content of six minerals in rice bran was 5.66 times on average as that in milled rice in all cultivars of three color rice. 2. Eight cultivars of the highest content of each mineral in rice bran and milled rice were recommended for commercial use and human consumption.

Objective To explore the clinical distribution states of human papillomavirus genotypes in tissues of 691 women with vulva condyloma acuminates in Nanjing city and Zhenjiang city in Jiangsu Province and genotyping clinical significance.Methods Polymerase chain reaction(PCR)and gene-chips technology were utilized for the detection of 23 kinds of HPV genotypes in tissue specimens from 619 women of vulva condyloma acuminates in Nanjing city and Zhenjiang city in Jiangsu Province.And related materials of all subjects were analyzed.Results In 691 women of vulva condyloma acuminates,597 women of HPV infecton,total infection rate of HPV was 86.40％(597/691),including single genotype infection rate of HPV was 51.38％(355/691),11、6 and 16 genotypes are the most common in single genotypes,they are successively 51.55％(183/355)、41.97％(149/355)and 3.38％(12/355).multiple genotypes infection rate of HPV was 35.02％(242/691),6+11、11+18、6+16 and 11+16 genotypes are the most common in multiple genotypes,they are successively 9.92％(24/242)、9.09％(22/242)、4.96％(12/242)and 4.13％(10/242).Conclusion The low-risk HPV types are the main factors to cause the female vulva CA,a few high-risk HPV types may cause warts as well in tissues of women with vulva condyloma acuminates in Nanjing city and Zhenjiang city in Jiangsu Province.The vulva examine of HPV types should be held to the vulva CA patients.This precaution will has extremely important meaning to the prevention and treatment of the female vulva CA and cervical lesion in our nation.

Objective: To analysis the clinical efficacy of dorsal digital nerves fasciocutaneous pedicle flap (DDNFPF) with superficial vein anastomosis in the treatment of the type III and type IV of fingertip defect, and the relationship between the incidence of vein crisis and superficial vein anastomosis. Methods: A total of 85 patients with 92 fingers, treated by DDNFPF from February, 2017 to December, 2018, were retrospectively analyzed. The superficial veins of 30 patients with 32 fingers were anastomosed, and 55 patients with 60 fingers were not. The difference of the superior rate and the incidence of venous crisis between superficial vein anastomosis and non-superficial vein anastomosis was compared by Chi-square test. The difference was considered as statistically significant when P<0.05. The regular postoperative followed-up was performed. Results: The average followed-up time was (7.0±2.9) months. The incidence of venous crisis in anastomosis group (1/32) was lower than that in non-anastomosis group (13/60). The difference was statistically significant (χ²=4.217, P<0.05) . There was no significant difference in the superior rate between the 2 groups after operation (96.8% and 90.0% respectively, χ²=0.596, P>0.05) . The repaired fingertips of the 2 groups were in good appearance, wear-resistant, stable holders and two-point discrimination was 5 to 8 mm. Conclusion DDNFPF for the type III and IV type of fingertip defect is safe and effective. A anastomosis of superficial veins in recipient area can significantly reduce the incidence of venous crisis.

Objective:To evaluate early weight-bearing walking with inflatable boots after repair of acute Achilles tendon rupture based on the concept of rapid rehabilitation.Methods:A retrospective study was conducted to analyze the data of 69 patients with acute Achilles tendon rupture who had been treated at Department of Orthopaedics, The Second Fuzhou Hospital Affiliated to Xiamen University from April 2020 to July 2021. There were 56 males and 13 females with a mean age of 37.0(31.0, 47.0) years and a body mass index of (23.7±2.6) kg/m 2. There were 55 cases of closed injury and 14 cases of open injury; 62 cases had simple Achilles tendon injury and 7 cases were complicated with neurovascular tendon injury. The patients were divided into 2 groups according to their rehabilitation methods. The treatment group of 23 cases was subjected to weight-bearing walking with inflatable boots early after repair while the control group of 46 cases to traditional plaster bracket fixation for 4 weeks before weight-bearing walking with inflatable boots. The 2 groups were compared in terms of hospitalization time, wound infection rate, return to sports time, single heel lifting time, Achilles tendon re-rupture rate, Victorian Institute of Sports Assessment (VISA-A), Achilles tendon total rupture score (ATRS), and American Orthopaedic Foot & Ankle Society ankle-hindfoot score (AOFAS-AH). Results:There was no statistically significant difference in the comparison of preoperative general data between the 2 groups, showing comparability ( P>0.05). All patients were followed up for 11 (10, 11) months after surgery. In the treatment group, the hospitalization time [4 (3, 5) days] and single heel lifting time [(12.5±1.4) weeks] were significantly shorter than those in the control group [6 (5, 9) days and (17.0±1.5) weeks], the return to sports time [21 (20, 22) months] was significantly earlier than that in the control group [23 (22, 24) months], and the VISA-A score [(89.4±1.3) points] was significantly higher than that in the control group [(78.5±1.7) points] ( P<0.05). There was no statistically significant difference in the wound infection rate between the 2 groups ( P>0.05). At 3 and 6 months after surgery, respectively, the treatment group had significantly higher ATRS scores [(85.5±1.4) and (89.0±1.6) points] and AOFAS ankle-hindfoot scores [(89.0±1.7) and (92.0±1.5) points] than the control group [(79.3±1.8) and (87.0±1.3) points; (80.2±1.9) and (88.4±1.9) points] (all P<0.05). In all patients, the AOFAS ankle-hindfoot score at 6 months postoperatively was significantly higher than that at 3 months postoperatively ( P<0.05). Achilles tendon re-rupture occurred in none of the patients. Conclusion:After repair of acute Achilles tendon rupture, compared with traditional plaster bracket fixation, early weight-bearing walking with inflatable boots can lead to better short-term clinical outcomes to enhance recovery after surgery without increasing the rate of open wound infection or re-rupture.

Beijing has been one of the epicenters attacked most severely by the SARS-CoV (severe acute respiratory syndrome-associated coronavirus) since the first patient was diagnosed in one of the city's hospitals. We now report complete genome sequences of the BJ Group, including four isolates (Isolates BJ01, BJ02, BJ03, and BJ04) of the SARS-CoV. It is remarkable that all members of the BJ Group share a common haplotype, consisting of seven loci that differentiate the group from other isolates published to date. Among 42 substitutions uniquely identified from the BJ group, 32 are non-synonymous changes at the amino acid level. Rooted phylogenetic trees, proposed on the basis of haplotypes and other sequence variations of SARS-CoV isolates from Canada, USA, Singapore, and China, gave rise to different paradigms but positioned the BJ Group, together with the newly discovered GD01 (GD-Ins29) in the same clade, followed by the H-U Group (from Hong Kong to USA) and the H-T Group (from Hong Kong to Toronto), leaving the SP Group (Singapore) more distant. This result appears to suggest a possible transmission path from Guangdong to Beijing/Hong Kong, then to other countries and regions.
