In order to detect coagulation factor VIII (FVIII) inhibitor in patients with severe hemophilia A (HA) and preliminarily study the genetic mutation in patients with inhibitor positive. Totally 58 patients with HA (FVIII: C < 1%) were enrolled. FVIII: C activity was measured by one-stage coagulation assay. FVIII inhibitor was screened by using APTT method and FVIII inhibitor in screened positive patients with HA was quantitatively analyzed by using Bethesda method. Using genomic DNA as template, 12, 14, 16 exons of FVIII in screened positive patients were amplified, and the mutations of amplified products were detected by direct sequencing. The results indicated that the FVIII inhibitor could be detected in 4 patients (6.9%) from 58 HA patients, no gene mutations in 12, 14, 16 exons of FVIII were found. It is concluded that the positive rate of FVIII inhibitor in HA patients is lower than that reported in literature. The causes of inhibitor production needs to further investigate.

BACKGROUNDDifferent kinds of minimally invasive surgery (MIS) procedures have now been used in total knee arthroplasty (TKA). Compared with traditional TKA procedure with a long skin incision, clinical studies showed MIS procedures had some advantages. Quadriceps sparing (QS) procedures are the most minimally invasive MIS procedure until now. This study was aimed to find the insertion types for Chinese patients' vastus medialis and if the QS procedure had some advantages in patients' early recovery.
METHODSBetween February 2006 and May 2007, 120 consecutive patients underwent unilateral primary TKA under general anesthesia, among whom 14 patients were lost to follow-up, the remaining 106 cases were enrolled in this study. Among the 106 cases there were 85 right knees, 21 left knees (15 men and 91 women, with a mean age of 65.1+/-7.4 years); osteoarthritis in 97 patients (91.5%) and rheumatoid arthritis in 9 patients (8.5%). MIS TKA was performed in 49 cases (MIS TKA group), while MIS-QS TKA in 57 cases (MIS-QS TKA group). During the operation, the type I, II and III insertions of the vastus medialis for all patients were recorded. Each knee was rated post-operatively according to the Hospital of Special Surgery (HSS) scoring system. Clinical follow-up was undertaken at 1 week, 2, 6, 12 and 24 weeks. Operating time and complications were recorded.
RESULTSThere was no statistically significant difference between the two groups for gender distribution, age, left or right knee incidence, pre-operative diagnosis, incidence of varus or valgus deformity. Of the 106 cases there was 1 (0.9%) case with a type I insertion of the vastus medialis, 4 (3.8%) cases with type II insertions, 101 (95.3%) cases with type III insertions. The HSS scoring was significantly different between the MIS-QS TKA group and MIS TKA group within the first two weeks post operation. From 2 weeks later to 24 weeks, no significant difference was found. The average operating time was (53.3+/-12.4) minutes in the MIS TKA group and (64.1+/-15.1) minutes in the MIS-QS TKA group (P<0.001). In the MIS-QS TKA group, 1 patient had delayed healing of the partial skin incision (1.8%). No other complications were found in either group.
CONCLUSIONSAlthough most of the Chinese patients had type III insertions of the vastus medialis, the MIS-QS TKA procedure showed less injury to the quadriceps than the standard MIS TKA and this could contribute to the earlier recovery of the patients. But a shorter skin incision and more tension on the skin may also lead to more skin complications.

OBJECTIVETo explore roles of mRNA and protein expressions of organic anion transporting polypeptide (oatp2b1) of rats with high fat diet and overstrain induced Pi deficiency syndrome in the transporting of damp turbidity.
METHODSTotally 24 SD rats were randomly divided into three groups, i.e., the normal group, the overstrain group, and the high fat diet group, 8 in each group. After successful modeling, one piece of tissues such as spleen, kidney, liver, lung, stomach, small intestine, and large intestine was taken from each rat. Rats of the overstrain group were bonded by specially made bondage cylinder, 3 h each time on odd days, and forced to swim in cold water (10 +/- 1) degrees C for 7 min on even days alternatively for twelve weeks. Rats in the model group and the normal group were fed with standard routine granular forage for 12 weeks. Rats in the high fat diet group were fed with high fat forage for twelve weeks. All rats drank and ate freely. The mRNA and protein expressions of oatp2b1 were detected in the seven tissues using RT-PCR and Western blot.
RESULTSThe mRNA expression of oatp2b1 in liver and kidney tissues of rats in the high fat diet group was higher when compared with that of the normal group and the overstrain group (P < 0.01, P < 0.05). The oatp2b1 mRNA expression in the normal group was sequenced from high to low as liver > lung > spleen > larger intestine > small intestine > kidney > stomach. The oatp2b1 mRNA expression in the overstrain group was sequenced from high to low as liver > lung > larger intestine > spleen > kidney > stomach > small intestine. The oatp2b1 mRNA expression in the high fat diet group was sequenced from high to low as liver > lung > spleen > small intestine > kidney > larger intestine > stomach. The oatp2b1 protein expression in the lung tissue was sequenced from high to low as the overstrain group > the normal group > the high fat diet group (P > 0.05). The oatp2b1 protein expression in the spleen tissue was sequenced from high to low as the high fat diet group > the normal group > the overstrain group (P > 0.05). The oatp2b1 protein expression in the kidney tissue was sequenced from high to low as the normal group > the overstrain group > the high fat diet group (P > 0.05). The oatp2b1 protein expression in the liver tissue was sequenced from high to low as the normal group > the high fat diet group > the overstrain group (P > 0.05). Of them, the oatp2b1 protein expressed extremely less in the stomach, large intestine, and small intestine. The oatp2b1 protein expression in the normal group was sequenced from high to low as lung >spleen > liver, kidney > stomach, larger intestine, and small intestine. The oatp2b1 protein expression in the overstrain group was sequenced from high to low as lung > spleen > kidney > liver > stomach, larger intestine, and small intestine. The oatp2b1 protein expression in the high fat diet group was sequenced from high to low as spleen > lung > kidney > liver > stomach, larger intestine, and small intestine. However, there was no statistical significance among the three groups by pair-wise comparison (P > 0.05).
CONCLUSIONSKidney and liver might play important roles in the transportation and transformation of damp under the state of Pi deficiency syndrome. Oatp2b1 may be one of the material bases involved in the transportation and transformation of damp turbidity. Pi's function of governing transportation and transformation of damp might not only include the functions of the gastrointestinal tract, but also include partial liver and kidney functions.

Objective: To evaluate the efficacy within the first 24 h post extracorporeal membrane pulmonary oxygenation (ECMO) and the impact of early efficacy on the prognosis of adult patients with fulminant myocarditis (FM). Methods: This retrospective case analysis study included hospitalized patients (age≥18 years) who were diagnosed with fulminant myocarditis from November 2016 to May 2021 in the First Affiliated Hospital of Zhengzhou University. Patients were divided into survival or non-survival groups according to treatment outcomes. The age, sex, treatments, drug use, ECMO use, clinical and laboratory data (before and 24 h after the use of ECMO) were analyzed. The change rate of clinical and laboratory data after 24 h use of ECMO was calculated to find differences between two groups. Multivariate logistic regression was used to analyze the related factors with in-hospital death and complication between the two groups. Results: A total of 38 FM patients treated with ECMO were included. There were 23 cases (60.5%) in the survival group, aged (39.6±13.7) years, and 17 (73.9%) cases were female. The total ECMO time was (134.4±71.3)h. There were 15 cases (39.5%) in non-survival group, aged (40.0±15.8) years, and there were 12(80.0%) female, the ECMO time was (120.1±72.4) h in this group. The proportion of tracheal intubation and continuous renal replacement therapy in the survivor group and dosage of norepinephrine within 24 h after ECMO implantation were significantly less than in non-survival group (all P<0.05). There was no significant difference in all efficacy related biochemical indexes between two groups before ECMO use. The levels of lactic acid, procalcitonin, creatinine, alanine aminotransferase, aspartate aminotransferase, creatine kinase-MB, cardiac troponin I and N-terminal B-type natriuretic peptide prosoma were significantly less in survival group than in non-survival group at 24 h after the use of ECMO (all P<0.05). Results of multivariate logistic regression analysis showed that the higher 24 h change rate of creatinine (OR=0.587, 95%CI 0.349-0.986, P=0.044) and creatine kinase-MB (OR=0.177, 95%CI 0.037-0.841, P=0.029) were positively correlated with reduced risk of in-hospital mortality. The central hemorrhage and acute kidney injury in survival group were less than in non-survivor group (P<0.05). Conclusions: After 24 h early use of ECMO in FM patients, the improvement of various efficacy related biochemical test indexes in the survival group was better than that in the non-survival group. Faster reduction of creatine kinase-MB and creatinine values within 24 h ECMO use is positively correlated with reduced risk of in-hospital mortality in adult patients with FM.

Objective: To analyze the spatiotemporal distribution of life expectancy (LE) and health-adjusted life expectancy (HALE) in Guangzhou from 2010 to 2019, and quantize the comprehensive impact of different causes and sequelae on health. Methods: The LE, HALE, and cause-excluded health adjusted life expectancy (CEHALE) were estimated using cause-of-death surveillance datasets from Guangzhou Municipal Center for Disease Control and Prevention from 2010 to 2019 and open data from the Global Burden of Disease Study. Joinpoint log-linear regression model was used to analyze the temporal trend and described spatial distribution. Results: In 2019, the LE in residents in Guangzhou was 82.9 years (80.1 years in men and 85.9 years in women), and the HALE was 75.6 years (74.0 years in men and 77.3 years in women). Compared with the urban fringe, the central urban area had higher LE and HALE, and the differences between LE and HALE were small. The LE and HALE in Guangzhou showed an increasing trend from 2010 to 2019. The LE increased by 2.8 years (AAPC=0.4, 95%CI: 0.3-0.4), with the increase of 2.8 years in men and 2.9 years in women. The HALE increased by 2.4 years (AAPC=0.3, 95%CI: 0.3-0.4), with the increase of 2.5 years in men and 2.2 years in women. The median healthy life lost due to communicable, maternal, neonatal, and nutritional diseases was 6.2 years (AAPC=-4.2, 95%CI: -5.3--3.1), while the median healthy life lost due to non-communicable diseases was 14.7 years (AAPC=1.6, 95%CI: 0.9-2.3), the median healthy life expectancy reduced by injury was 6.3 years (AAPC=-3.5, 95%CI: -4.5--2.6). Musculoskeletal disorders, skin and subcutaneous diseases, cardiovascular diseases, nutritional deficiencies, diabetes and kidney diseases were the top five diseases causing healthy life expectancy loss. Conclusion: The LE and HALE in residents in Guangzhou increased steadily from 2010 to 2019, but the quality of life in the urban fringe was lower than that of the central urban area. Non-communicable diseases were the leading causes of healthy life expectancy loss. Health policies and prevention measures should be developed according to area specific characteristics, and social medical resources should be rationally allocated to key diseases to reduce their disease burden.

OBJECTIVE:
Improvement in the quality of life is reflected in the narrowing of the gap between health-adjusted life expectancy (HALE) and life expectancy (LE). The effect of megacity expansion on narrowing the gap is rarely reported. This study aimed to disclose this potential relationship.
METHODS:
Annual life tables were constructed from identified death records and population counts from multiple administrative sources in Guangzhou, China, from 2010 to 2020. Joinpoint regression was used to evaluate the temporal trend. Generalized principal component analysis and multilevel models were applied to examine the county-level association between the gap and social determinants.
RESULTS:
Although LE and HALE in megacities are increasing steadily, their gap is widening. Socio-economic and health services are guaranteed to narrow this gap. Increasing personal wealth, a growing number of newborns and healthy immigrants, high urbanization, and healthy aging have helped in narrowing this gap.
CONCLUSION
In megacities, parallel LE and HALE growth should be highly considered to narrow their gap. Multiple social determinants need to be integrated as a whole to formulate public health plans.
