Objective To explore the suitable type of macroporous adsorbent resin to purity swertiaman from Swertia pesudochinensis Hara., and determine the parameters and conditions for its purification procedures. Method Purification effect of 8 types of macroporous resins used to purify the Swertia pesudochinensis Hara. were inspected, with the content of swertiaman as index. Result HPD-100 type resin showed better effect than others, it had optimum adsorption and elution parameters with its dynamic saturated adsorption ratio was 70.48 mg/g. After eluted with 2 BV of distilled water, 4 BV 30% ethanol and collected, the content of swertiaman in the spray dried powder was 52.29%. Conclusion HPD-100 types macroporous resin showed a better comprehensive adsorption property and can be used to enrich and purify the swertiaman included active fraction of iridoid glycosides for industrialization.

Objectives:To observe the role of parenteral nutrition(PN) in the elderly postoperative patients with gastric carcinoma. Methods:Forty cases were randomly divided into two groups. One group received PN after operation as PN group and another group was supported only with the general treatment without PN as control group. Results:①The rate of postoperative complications was 15% (3/20) with no death in PN group, and it was 45%(9/20) with mortality rate of 5%(1/20) in control group. ② Between the two groups, there were very significant differences in nitrogen balance, body weight, creatinine height index(CHI), serum albumin, serum transferrin and blood urea nitrogen(BUN) at the 8th postoperative day( P

Objective To investigate effects of pedicle processing methods on the survival and appearance of the pedicle flaps. Methods The study involved 17 patients with soft tissue defects of extremities treated with the “exclamation mark” shaped pedicle flaps from October 2009 to January 2011.The traditional pedicled rotation flaps was designed to be a tennis racket-like shape,then the rotational pedicle was designed to small round tension reduction flap and pedicled rotation flaps,which contributed to formation of the “exclamation mark” shaped pedicle flaps.The soft tissue defects was located at the upper extremity in three patients and at lower extremity in 14,with defect areas of 4.0 cm× 7.2 cm-5.8 cm × 14.0 cm.There used two superficial radial nerve vasotrophic flaps,one ulnar artery supra-carpal cutaneous flap,eight sural neurocutaneous vasotrophic flaps and six saphenous nerve vasotrophic flaps.Results All flaps survived at Ⅰ stage except that one flap had partial distal necrosis postoperatively,which was cured after dress change.The follow-up ranged from six months to one year,which showed unobvious swelling of the survived flaps and good appearance of the rotation point of the pedicle. Conclusion The “ex(c)lamation mark” shaped pedicle flaps can reduce entrapment of the distal pedicle,promote venous drainage,improve survival and modify the appearance of the flaps.

Objective To improve the recognition of treatment of adult T lymphoblastic lymphoma (TLL) with Hyper-CVAD regime.Methods The turnovers of 7 cases treated with Hyper-CVAD regime were summarized.Results Among the 7 cases,1 case died after the first unfinished chemotherapy,1 case gained complete remission before autologous stem cell transplantation but relapsed after transplantation,3 cases gained complete remission until now,2 cases without transplantation relapsed and then gave up following treatments after treating with ICE regime or the virgin regime,but the therapeutic effects were poor.Conclusions Adult TLL should get early chemotherapy treatments,and some special characteristics should be noted,the treatment does not relate to the stage,the chemotherapy treatment should be carried out regularly and enough,radiation of mediastinum mass can be applied after 4 cycles of Hyper-CVAD regime,choose suitable transplantation method.

Objective To preliminarily understand the infection of Chikungunya virus (CHIKV) in Cangyuan County, a southern border area of Yunnan Province, and provide a reference basis for the prevention and control of Chikungunya fever. Methods In April 2020, a total of 400 serum samples from individuals seeking medical care at the People's Hospital of Cangyuan County in Yunnan Province were collected. Among these, 121 samples were from healthy individuals undergoing physical examinations, and 279 samples were from patients with fever. The serum samples collected underwent CHIKV neutralizing antibody testing using a serum micro-neutralization assay. Real-time fluorescence quantitative RT-PCR was used to detect CHIKV nucleic acid in the samples, followed by analysis of the test results. Results The results of neutralizing antibodies showed that 18 of the 400 human serum samples were positive for neutralizing antibodies against CHIKV, with an overall positivity rate for serum samples of 4.5% (18/400). Among the 279 serum samples collected from patients with fever, 18 were positive for neutralizing antibodies against CHIKV, with a positive rate of 6.45% (18/279), and the neutralizing antibody titers ranged from 1∶10 to 1∶320. The results of 121 healthy human serum samples were negative for neutralizing antibodies against CHIKV. The results of real-time fluorescence quantitative RT-PCR showed that 3 of the 400 human serum samples were positive for CHIKV nucleic acid, and the positive rate was 0.75% (3/400). Among the 279 serum samples collected from patients with fever, 3 samples were positive for CHIKV nucleic acid, with a positive rate of 1.08% (3/279), and Ct values ranged from 36.58 to 37.74. While all healthy human serum samples were negative for CHIKV nucleic acid. Conclusions The findings indicate that infection of CHIKV exists in the population of Cangyuan County, a southern border area of Yunnan Province, and an outbreak of the disease is occurring. Therefore, it is necessary to strengthen the monitoring, prevention, and control of CHIKV in this area.

OBJECTIVE:
To explore the relationship between the expression changes of cytokines, interleukin-6 (IL-6), interleukin-8(IL-8), and tumor necrosis factor-alpha (TNF-alpha), and the wound time following explosive injury to rabbit's chest.
METHODS:
The rabbit's model of explosive injury was established. The expression levels of IL-6, IL-8 and TNF-alpha in the plasma were detected by ELISA method at different wound time (0.5-12h).
RESULTS:
The level of IL-6 increased at 3h after wounding and reached peak at 6 h. The level of IL-8 increased at 1 h and reached peak at 6 h. The level of TNF-alpha increased at 0.5 h and reached peak at 3 h.
CONCLUSION
IL-6, IL-8 and TNF-alpha have a time-related expression after explosive injury.

OBJECTIVE:
To analyze the case characteristics of poisoning by exhaust gas of the imperfect combustion of natural gas and provide references for forensic identification and prevention of such accidents.
METHODS:
Twenty-two cases of poisoning by exhaust gas of the imperfect combustion of natural gas in Minhang District during 2004 to 2013 were collected. Some aspects such as general conditions of deaths, incidence time, weather, field investigation, and autopsy were retrospectively analyzed.
RESULTS:
In the 22 cases, there were 15 males and 16 females. The age range was between 2 and 82 years old. The major occurring time was in January or February (8 cases in each) and the cases almost occurred in small area room (21 cases). There was wide crack next to the exhaust port when the gas water heater was been used in all cases.
CONCLUSION
There are more prone to occurrence of exhaust gas poisoning of imperfect combustion of natural gas in small area room with a ventilation window near the exhaust port of gas water heated. It shows that the scene of combustion exhaust gas poisoning should be more concerned in the cold season.
