Objective To explore the acquired deficiencies of vitamin K-dependent coagulation factors in etiology, clinical characteristics and treatment. Methods Retrospective analysis was performed on the data of etiology, clinical manifestations of 45 patients with acquired deficiencies of vitamin K-dependent coagulation factor. All patients were treated with Vitamin K1 10 -40 mg/d, i. v. , for three months. Some patients with severe blooding were additionally treated with fresh freezing plasma or prothromibin complex. Prothrombin time(PT) and activated partial thromboplastic time(APTT) were measured using Stago automatic blood coagulation analyzer before and after treatment. Ⅱ , Ⅶ, Ⅸ and Ⅹ were measured in some patients. Results Among the 45 cases, no certain cause was found in 19 cases (42.2%), anticoagulant rodenticides poison was a common cause ( 11 cases,42.3% ). The main presentations was hemorrhage, the most common bleeding sites were mucosa (77.8%) (35/45)and hematuria (46.7%) ( 21/45 ). After vitamin K1 treatment, PT and APTT had shortened remarkably from ( 110.35 ± 35.36 ) s,(98.91 ±48.98)s to (13.48 ±2. 17)s,(33.25 ±6.95)s,respectively(t=19.10 and 6.19,Ps ＜0.01)and the activities of factor Ⅱ、Ⅶ、Ⅸ、Ⅹ had rapidly increased from ( 17.48 ± 10.93 ) %, ( 10.23 ± 5.68 )%, ( 11.98 ±4.69)%,(12.93±7.48)% to (70. 12 ±21.31)%,(92.76 ±29. 15)%,(88.64 ±40. 21)%,(63.97 ±20.11)%(t=12.13,14.43,13.27and9. 74,respectively,Ps＜0. 01).Conclusions The histories of patients with acquired deficiencies of vitamin K-dependent coagulation factors are usually hiding, therefore it is easily misdiagnosed. It is worth of detecting PT and APTT in diagnosis and monitoring. Using vitamin K1 10 -40 mg/d is effective and safety.

ObjectiveTo observe effect of head and body acupuncture and moxibustion on stroke.Methods183 stroke patients were randomly divided into 3 groups, head acupuncture and moxibustion, body acupuncture and moxibustion, and head body acupuncture and moxibustion. After two months treatment, effects of 3 groups were evaluated.ResultsThere were no differences between head group and body group, body group and head body group, but there was significantly difference between head body group and head group (P<0.05).ConclusionThe head body acupuncture and moxibustion can gain the best clinical effect on stroke patients compared with simply head or body acupuncture and moxibustion.

Objective: To learn the characteristics of varicella breakthrough cases aged under 14 years in Haizhu District, Guangzhou City and the effects of vaccination on incidence of breakthrough cases, so as to provide the basis for improving varicella vaccination strategy. Methods: Data of varicella cases aged under 14 years and vaccination in Haizhu District were collected through Chinese Disease Prevention and Control Information System and Guangdong Provincial Vaccination and Vaccine Circulation Management Information System from 2015 to 2022. Temporal distribution, population distribution and vaccination history of varicella breakthrough cases were descriptively analyzed. Effects of primary immunization age and inoculation interval on breakthrough interval were analyzed using least square method fitting bi-cubic functional equation. Results: A total of 4 008 varicella breakthrough cases aged under 14 years were reported in Haizhu District from 2015 to 2022, accounting for 29.16% of all varicella cases. There were mainly 1-dose breakthrough cases, with 3 607 cases accounting for 90.00%. The proportion of 1-dose breakthrough cases showed a downward trend, while the proportion of 2-dose breakthrough cases showed an upward trend (both P<0.05). The epidemics peaked from March to May and from November to January, with a male-to-female ratio of 1.41︰1. The age of onset was mainly at 4 to 6 years, with 1 189 cases accounting for 29.67%. The primary immunization age was mainly ranged from 12 to <24 months, with 2 662 cases accounting for 66.42%. Vaccination of the second dose was concentrated at the age of 48 to <60 months, with 136 cases accounting for 33.92%. The breakthrough interval was relatively long among cases with primary immunization age at 12 to <36 months and inoculation interval within 45 months, with a median breakthrough interval of 25.24 (interquartile range, 20.00) months. Primary immunization age and inoculation interval were negatively correlated with breakthrough interval (P<0.05). Conclusions The varicella breakthrough cases aged under 14 years in Haizhu District from 2015 to 2022 were mainly occurred at the beginning of the new term, with a high incidence among preschool children. It is recommended that children receive the first dose of varicella vaccine within 36 months of age and booster within 45 months of interval.

Objective To investigate the effects of ulinastatin on pulmonary and hepatorenal function of elderly patients undergoing resection of esophageal cancer. Methods The clinical data of 40 elderly patients with esophageal cancer who had been admitted to Southwest Hospital from January 2005 to January 2008 were retrospectively analyzed. All the patients were randomly divided into control group (n = 20) and ulinastatin group (n = 20) according to random number table. Patients were administered with total parenteral nutrition, and patients in ulinaslatin group were additionally instilled with 4×10~5 U/d of ulinastatin. The levels of PaO_2, PaCO_2, PaO_2/FiO_2, alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (Tbil), blood urea nitrogen, creatinine and uric acid were detected preoperatively and at postoperative day 2 and day 6. All the data were analyzed by t-test and chi-square test. Results The levels of PaO_2 and PaO_2/FiO_2 were (87.3±4.2) mm Hg (1 mm Hg =0.133 kPa) and (416±20)mm Hg in ulinastatin group, which were significantly higher than (79.0±4.3)mm Hg and (376±20)mm Hg in control group (t =6.2, 6.2, P <0.05). The levels of ALT, AST and Tbil were (23±7)U/L, (38±8)U/L and (13.4±3.0) μmol/L in ulinastatin group, and (39±8) U/L, (50±9) U/L and (24.5±6.0) μmol/L in control group, with significant difference between the 2 groups (t = 7.0, 4.4, 7.6, P < 0.05). The levels of uric acid, blood urea nitrogen and creatinine were (279±84) μmol/L, (4.1±1.7) mmol/L and (66±12) μmol/L in ulinastatin group, and (386±67)μmol/L, ( 8.9±2.7) mmol/L and (95±38) μmol/L in control group, with significant difference between the 2 groups (t = 4.4, 6.4, 3.3, P < 0.05). The recurrence of complications in ulinastatin group was significantly lower than that in control group (χ~2 = 4.8, P <0.05). Conclusion Postoperative supplementation of ulinastatin and total parenteral nutrition is helpful in improving the pulmonary and hepatorenal function of elderly patients undergoing resection of esophageal cancer.
