BACKGROUND:Deep vein thrombosis and pulmonary embolism are certainly related to seasons.
OBJECTIVE:To analyze whether there is a seasonal pattern for deep venous thrombosis (DVT) after total hip and knee arthroplasty.
METHODS:We retrospected 866 patients (1 114 joints) underwent total hip and knee arthroplasty. There were 506 cases of total hip arthroplasty, including 287 male cases and 219 female cases, and 608 cases of total knee arthroplasty, including 133 male cases and 475 female cases. The average age was (60.98±0.87) years. After arthroplasty, patients were given color Doppler ultrasound in the deep veins of the lower limbs and pelvis to analyze the correlation between occurrence of deep vein thrombosis and seasons.
RESULTS AND CONCLUSION:There was a significant difference in the incidence of deep vein thrombosis in summer and winter (χ2=7.190, P=0.007), in summer and spring (χ2=6.995, P=0.008), as wel as in summer and autumn (χ2=5.663, P=0.017). No statistical differences were tested in spring and autumn, in autumn and winter, and in spring and winter (P>0.05). These findings indicate that there is a seasonal variation of deep venous thrombosis after arthroplasty, and the highest incidence of deep vein thrombosis is in winter.

OBJECTIVETo identify the relationship between genetic polymorphisms of peroxisome proliferator-activated receptor alpha (PPARalpha) intron 1A/C and metabolic syndrome (MS) in a Chinese population.

METHODSA population-based case-control study was conducted in Suzhou city, Changshu County and Ganyu County in Jiangsu Province China, on the basis of an ongoing cohort study and 2348 cases were investigated. After the exclusion of the known MS cases, 1847 eligible subjects were successfully followed-up and their waist circumference (WC), body mass index, blood pressure, total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), triglycerides (TG) and fasting plasma glucose were measured. Newly diagnosed MS patients were recruited as cases, controls were individual matched with each case. TaqMan fluorescence probe method was used to detect the genetic polymorphism of PPARalpha intron 1A/C.

RESULTSThe current analysis consisted of 389 MS patients and 389 matched controls. The C allele gene frequency of PPARalpha intron 1A/C in the case group was 22.24% (173/778), lower than that in the control group, which was 24.68% (192/778); whereas the difference was not statistically significant (chi(2) = 1.29, P > 0.05). In the genotypes AA + AC and CC, MS patients were accounted for 50.70% (363/716) and 41.94% (26/62) and hyperglycemia accounted for 21.37% (153/716) and 11.29% (7/62). Compared to the genotypes AA + AC, genotype CC was observed to be inversely associated with hyperglycemia (the adjusted OR = 0.39; 95%CI: 0.17 - 0.90) but not related to the occurrence of MS (OR = 0.75; 95%CI: 0.44 - 1.28) and other components of MS e.g., abdominal obesity (the adjusted OR = 0.67; 95%CI: 0.38 - 1.17), hypertriglyceridemia (the adjusted OR = 0.97; 95%CI: 0.53 - 1.76), low HDL-C (the adjusted OR = 0.72; 95%CI: 0.41 - 1.25) and hypertension (the adjusted OR = 0.72; 95%CI: 0.42 - 1.25) all P values > 0.05.

CONCLUSIONC allele of PPARalpha intron 1A/C is not found to be associated with MS in the Chinese population. But comparing with the genotypes AA + AC, there is an inverse association between CC genotype and hyperglycemia.

Objective To examine the associations between occupational physical activity,heredity factors and metabolic syndrome (MS) in a Chinese population.Methods Based on the MS cohort study in Jiangsu province,subjects were followed-up,and blood samples were collected at the same time for biochemical indicators measurement.Newly confirmed MS patients according to US.National Cholesterol Education Program Adult Treatment Guidelines Ⅲ (NCEP-ATP Ⅲ ) were recruited as eases.Controls were 1 :1 matched with eases by region,gender and age (±2 years).In total,389 MS patients and 389 eontrols were recruited as study subjects.Nested ease-control study was applied for the present analysis.TaqMan fluorescence probe method was used to detect the genetic polymorphism of PPARα intron 1A/C (rs135539).Results (1)Compared to low physical activity group,the subjects with heavy physical activity were positively associated with MS (OR=2.18,95%CI:1.08-4.38).(2)The subjects,with a family history of hypertension (OR= 1.44,95% CI:1.02-2.03 )or type 2 diabetes (OR=3.25,95CI:1.28-8.20),were significantly indreased the occurrence of MS.(3)The genotype(AA,AC,CC) of PPARα intron 1A/C was not found to be related to MS.The OR of AC and CC genotype (compared to the genotype AA) were 0.98(95%CI:0.70-1.36) and 0.75 (95% CI:0.44-1.29) ,respectively.(4) Effect modifications were observed between family history of hypertension and moderate physical activity (OR=2.47,95% CI:1.00-6.06 ) or heavy physical activity (OR=3.82,95%CI:1.31-11.15) on the development of MS.Conclusion Heavy physical activity,with family history of hypertension or type 2 diabetes,seemed to be positively correlated with the risk of MS.Effect modifications were observed between occupational physical activity and family history of hypertension which might be associated with an increased risk of MS.

Objective: To observe the clinical efficacy of 'Tong Du Yun Pi' (Governor Vessel-unblocking and spleen-promoting) manipulation in treating infantile diarrhea in autumn. Methods: Eighty-four kids were divided into a control group and an observation group using the random number table method, with 42 cases in each group. The control group was intervened by oral administration of montmorillonite powder, and the observation group was given additional 'Tong Du Yun Pi' pediatric massage (tuina) treatment. After treatment, the traditional Chinese medicine (TCM) symptoms scores, symptom improvement time, clinical efficacy and immune function indicators were compared between the two groups. Results: After treatment, the total effective rate was 95.2％ in the observation group versus 76.2％ in the control group, and the between-group difference was statistically significant (P<0.05); each item score in TCM symptoms was notably lower in the observation group than in the control group (all P<0.05); among the effective cases, the times to restore normal defecation, relieve abdominal bloating, arrest vomiting, and bring down the fever were markedly shorter in the observation group than in the control group, and the between-group differences were statistically significant (all P<0.05); the levels of immunoglobulin (Ig) G, IgM, CD4+ and CD4+/CD8+ were significantly higher and CD8+ was significantly lower in the observation group than in the control group (all P<0.05). Conclusion: In the treatment of infantile diarrhea in autumn, based on oral administration of montmorillonite powder, 'Tong Du Yun Pi' manipulation can notably improve diarrheal symptoms, shorten disease duration, and strengthen the immunity of kids, producing more significant efficacy than oral administration of montmorillonite powder.

OBJECTIVETo study the causes of orchiectomy in different age groups.

METHODSWe retrospectively reviewed the clinical data about 291 cases of orchiectomy performed between March 1993 and October 2014 and analyzed the causes of surgery and their distribution in different age groups.

RESULTSThe main causes of orchiectomy were testicular torsion (45.8%), cryptorchidism (32.5%) and testicular tumor (16.9%) in the patients aged 0-25 years, testicular tumor (42.4%), cryptorchidism (25.9%) and tuberculosis (10.6%) in those aged 26-50 years. Prostate cancer was the leading cause in those aged 51-75 years (77.6%) or older (84.0%)), and testicular tumor was another cause in the 51-75 years old men (10.2%). Prostate cancer, testicular tumor, cryptorchidism, and testicular torsion were the first four causes of orchiectomy between 1993 and 2009. From 2010 to 2014, however, testicular tumor rose to the top while prostate cancer dropped to the fourth place.

CONCLUSIONThe causes of orchiectomy vary in different age groups. The proportion of castration for prostate cancer patients significantly reduced in the past five years, which might be attributed to the improvement of comprehensive health care service.

OBJECTIVETo investigate the expression characteristics of the gene of coiled-coil domain-containing protein 70 (Ccdc70) in the mouse testis and its potential role in spermatogenesis.

METHODSUsing expression profile microarray, we screened the mouse testis-specific gene Ccdc70, studied its expression characteristics in the mouse testis by RT-PCR, real-time PCR, Western blot and immunohistochemistry, followed by bioinformatic analysis of the Ccdc70 protein.

RESULTSThe Ccdc70 gene was expressed highly in the testis but lowly in the epididymis of the mice. The Ccdc70 protein was expressed mainly in the spermatocytes and round spermatids of the testis and in the epithelial cells of the epididymis. Bioinformatic analysis showed a structural domain in the Ccdc70 protein, which was highly conserved in mammalian evolution.

CONCLUSIONThe Ccdc70 gene is highly expressed in the mouse testis and mainly in the spermatocytes, round spermatids, and epididymal epithelial cells, which indicates that it is involved in the regulation of spermatogenesis and epididymal sperm maturation.

OBJECTIVETo evaluate the expression of vascular endothelial growth factor (VEGF) and its receptors KDR and Flt1 in patients with acute myeloid leukemia (AML).

METHODSThe expression of VEGF and its receptors mRNA was assayed by RT-PCR, the plasma of VEGF by ELISA.

RESULTSIn 13 AML cell lines, the expression of VEGF, KDR and Flt1 mRNA were found in 13 (100%), 7 (53.8%) and 12 (92.3%), respectively. There were 21 (65.6%), 1 (3.1%), and 17 (53.1%) of 31 (AML) patients bone marrow mononuclear cells (BMMNCs) expressing VEGF, KDR and Flt1 mRNA, respectively. None of BMMNCs from 3 normal donor and CD(34)(+) cells from 2 normal donor was found to express VEGF, KDR and Flt1 mRNA. The plasma level of VEGF of 39 patients (new diagnosed, relapsed and secondary-AML) before treatment was (135.3 +/- 87.9) ng/L which was significantly higher than that of 15 complete remission (CR) patients (80.6 +/- 36.9) ng/L and 12 normal donors (80.6 +/- 33.1) micro g/L (P = 0.028, 0.007). The plasma level of VEGF of 15 non-responsive patients was (188.2 +/- 118.6) ng/L after two cycles of chemotherapy which was higher than that of 20 CR patients [(104.2 +/- 30.9) ng/L] (P = 0.004).

CONCLUSIONVEGF and its receptors KDR and Flt1 mRNAs were expressed in BMMNCs of AML patients. The plasma level of VEGF directly affected the response to chemotherapy in AML patients.

OBJECTIVETo evaluate the safety and feasibility of laparoscopic cylindrical abdominoperineal resection.

METHODSSix patients with rectal adenocarcinoma within 3 cm above the anal verge underwent laparoscopic cylindrical abdominoperineal resection. Transabdominal levator transaction was performed laparoscopically, with no position change during the perineal operation. Pelvic reconstruction was achieved using human acellular dermal matrix mesh in 3 patients.

RESULTSAll the procedures were successfully performed without any intraoperative complications, laparoscopy-associated complications, or conversion to the open approach. The mean operation time was 186.7 minutes and intraoperative blood loss was 101.7 ml. All the specimens had a cylindrical shape with levator muscles attached to the mesorectum and circumferential margins were all negative. No adverse incidence followed the pelvic reconstruction using human acellular dermal matrix mesh.

CONCLUSIONSLaparoscopic transabdominal transection of the levator muscles without position change and pelvic floor reconstruction with human acellular dermal matrix mesh is feasible. This procedure simplifies cylindrical abdominoperineal resection which is aggressively invasive and technically complicated. The oncologic outcomes are acceptable and complications are less.

Authors raised that staging based strategies and practice of integrative medicine (IM) by combining syndrome typing and disease identification, and choosing suitable measures in accordance with different persons and seasonal conditions after more than ten years' clinical practice and researches. Radical operation as prior (as evil eliminating) and strengthening vital qi in perioerative period are best strategy for promoting rapid rehabilitation of early stage prostate cancer patients. Strengthening body resistance to eliminate evil was used in treating advanced prostate cancer patients. For example, a comprehensive treatment program for hormone-dependent patients was combined with endocrinotherapy and Chinese herbs for synergisic efficacy-enhancing actions. In this way, these patients' quality of life (QOL) were improved and time to castration resistant prostate cancer (CRPC) was delayed, even some patients were clinically cured. There are lack of effective medicines and methods for CRPC patients. Greatly tonifying original qi is mainly used for improving their clinical symptoms and prolonging survivals. Practice has proved staging based strategies and practice of IM has favorable advantages in treating prostate cancer, especially showing prospect in prolonging survival and postponing progression of advanced prostate cancer patients. Besides, it also could provide beneficial considerations and inspiration for combination of syndrome typing and disease identification.
