OBJECTIVETo observe the impacts of the acupoint catgut implantation on postpartum pain of uterine contraction with qi and blood deficiency.
METHODSOne hundred and ten primiparas of natural delivery differentiated as qi and blood deficiency pattern in TCM were selected as the subjects. They were randomized into an acupoint catgut implantation group (55 cases) and a routine nursing group (55 cases). In the acupoint catgut implantation group, the catgut was implanted in Zigong (EX-CA 1), Zusanli (ST 36), Sanyinjiao (SP 6), Pishu (BL 20) and Geshu (BL 17) in 6 h after delivery; additionally, the routine post-delivery nursing was adopted. In the routine nursing group, the routine post-delivery nursing was applied simply. Visual analogue scale (VAS) and the pain relief time of uterine contraction were compared in 24 h, 48 h, 72 h and 96 h after acupoint catgut implantation between the two groups.
RESULTSVAS Scores in 24 h, 48 h, 72 h and 96 h after acupoint catgut implantation in the acupoint catgut implantation group were lower apparently than those in the routine nursing group (3.31 +/- 0.39 vs 4.31 +/- 0.29, 1.86 +/- 0.29 vs 2.66 +/- 0.25, 0.89 +/- 0.21 vs 1.59 +/- 0.24, 0.35 +/- 0.10 vs 0.69 +/- 0.13, all P < 0.05). The pain relief was achieved in (72.06 +/- 6.83) h in the acupoint catgut implantation group and was (123.42 +/- 11.12) h in the routine nursing group. The pain relief in the acupoint catgut implantation group was achieved more quickly (P < 0.01).
CONCLUSIONThe intervention of acupoint catgut implantation in 6 h after natural delivery in primiparas prevents effectively postpartum pain of uterine contraction.

2.Efficacy and visual related quality of life of Ozurdex in the treatment of RVO-ME
International Eye Science 2021;21(4):689-693
AIM: To study the clinical efficacy, complications and visual related quality of life(VRQoL)of Ozurdex in the treatment of macular edema secondary to retinal vein occlusion(RVO-ME).
METHODS: Totally 30 patients with ME, which had developed secondary to either CRVO(13 eyes)or BRVO(17 eyes), were monitored for 6mo after treatment with Ozurdex in the Department of Ophthalmology of our Hospital. We measured the best corrected visual acuity(BCVA), intraocular pressure(IOP), central macular thickness(CMT)at different time after treatment(1wk, 1mo, 2mo, 3mo, 4mo, 5mo, and 6mo after treatment), and we also measured the Chinese version vision related quality of life questionnaire-25(CVRQoL-25)at 3mo after treatment and compared them separately with the ones measured before treatment to evaluate the efficacy, adverse reactions and the visual related quality of life.
RESULTS: Generalized estimation equation results showed that BCVA, CMT and IOP all had differences at different time points(P<0.001). A BCVA increase was achieved and CMT decreased in all patients at any time point after the onset of treatment(P<0.001). The changes of BCVA and CMT were the largest in the 2mo compared to the baseline(P<0.001). The score of CVRQol-25 at 3mo after treatment was significantly higher than that before treatment and then the central retinal thickness decreased and a BCVA increased compared to the baseline level(P<0.01). The score of CVRQoL-25 at 3mo was negatively correlated both with the LogMAR BCVA evaluated before treatment and at 3mo after treatment(rs= -0.717, -0.746, all P<0.001); Meanwhile, the score of CVRQoL-25 was also negatively correlated with CMT at 3mo after treatment(rs= -0.862, P=0.001). In 19 eyes(63%)of the patients with RVO-ME,a relapse was observed after a follow-up time of 1-3mo and the average recurrence time was(2.8±0.5)mo. In follow-up of 6mo, about(2.3±0.4)intravitreal Ozurdex injections per eye was observed. The increase in IOP was observed at 1wk, 1, 2, 3mo after pretherapy(P<0.05). The mean IOP values reached a peak at 2mo after injection, which rose(7.85±0.32)mmHg above the baseline level(P<0.05)and decreased to normal at 4mo after treatment. 10% of patients had an elevation in IOP above 25mmHg, which could be medically controlled and 4 eyes(13%)of patients had cataract formation, two of which needed to surgery.
CONCLUSION: Ozurdex proved to be efficacious with increase in visual acuity and reduction of central retinal thickness and improve the visual function-related quality of life of RVO-ME patients. After single injection of Ozurdex, visual acuity benefited for 2-3mo. 63% of the patients relapsed at about 3mo after treatment. Adverse reactions associated to the use of Ozurdex include the formation of cataracts and an increase in IOP.

Objective To investigate the prevalence of anti-hepatitis E virus (HEV) and genotypes of hepatitis E virus in 8 species of animals including swine, cattle, sheep, horse, donkey, dog, chicken and duck in the suburb of Beijing. Methods Serum samples were collected from the 8 species of animals, and fecal samples of younger swine were collected from 2 stock farms. Anti-HEV was detected by Double Antigen Sandwich Assay. HEV RNA from fecal samples was detected by a reverse transcription nested polymerase chain reaction (RT-nPCR). Parts of the PCR products were cloned and sequenced. The swine HEV sequences were analyzed genetically. Results The positive rates of anti-HEV in serum specimens of swine, cattle, horse, donkey, sheep, dog, duck and chicken were 80.43%(481/598), 15.02%(52/346), 14.29%(40/280) ,0(0/26) ,9.88%(33/334), 0(0/ 21) ,3.03% (7/231) and 2.53%(8/316), respectively. The anti-HEV prevalence of adult swine(≥6 months)and younger swine(≤3 months)were 87.86%(369/420)and 62.92%(112/178)respectively. 74 of 111 (66.67% ) pig faces were positive for HEV RNA. Sequence analysis on these positive samples showed that there were 6 groups of HEV designated as bjsw1, bjsw2, bjsw3, bjsw4, bjsw5 and bjsw6. The 6 strains of HEV shared 94.5%-99.6% sequence identity of partial HEV ORF2 nucleotide with each other. The identities of HEV ORF2 nucleotide sequences between the 6 strains and genotype 1, 2, 3 and 4 were 75.6%-78.6% , 75.6%-76.2%, 77.1%-80.7% and 83.7%-94.5%, respectively. The sequence identity between the 6 strains and human HEV genotype 4d was 90.0%-94.5% . Conclusion HEV infection was seen in swine, cattle, horse, sheep, duck and chicken in the suburbs of Beijing. The anti-HEV positive rate appeared the highest in swine and the lowest in dog and donkey. The six strains of HEV isolated from younger swine belonged to genotype 4d.

OBJECTIVE:
To investigate the role of multiple serological methods in the identification of complex antibodies.
METHODS:
The blood group antigens were detected by saline and microcolumn agglutination methods. The saline method was used to screen and identify IgM-type antibodies in the patient's serum, while the polybrene, anti-globulin, microcolumn agglutination, enzymic and absorption-elution methods were used to screen and identify IgG-type antibodies.
RESULTS:
The patient was B/CCDee/Jk(a-b+)/Fy(a-b+) blood type. The serum reacted with panel cells, and the reaction presented anti-E pattern in the saline medium. It was fully positive in the microcolumn agglutination card, except 2 negative ones after using papain to treat the panel cells. Referring to the pattern table, it was concluded that there existed anti-c, anti-E, and anti-Jka antibodies, and one antibody corresponding to an antigen that was easily destroyed by papain. The red blood cells with specific phenotype were selected for absorption-elution to identify IgG-type anti-c, anti-E, anti-Jka and anti-Fya antibodies.
CONCLUSION
It is confirmed that IgM-type anti-E, and IgG-type anti-c, anti-E, anti-Jka and anti-Fya antibodies exist in the patient's serum by multiple serological methods.

OBJECTIVETo explore the reconstitution of immune function and viral suppression condition and to analyze the occurrence of drug resistance HIV-1 variants and its prevalence after using HAART in Guangxi Autonomy Region.
METHODSFrom July 2004 to October 2005, 133 HIV infected individuals who had received HAART for more than three months were recruited, and 58 infected persons with no antiviral therapy were selected as controls. Questionnaire was used to collect information about the adherence of HAART therapy. Immune reconstruction and viral suppress conditions were obtained by CD4+ counts and viral load and RT-PCR were used to amplify the PR and RT regions of HIV-1 genome while HIV-1 drug resistance rates were analyzed to show the occurrence and prevalence in both treated and naive patients.
RESULTSIn terms of CD4+ T cell counts: 70.69% of the treated patients showed obvious increase and 23.28% had no apparent change but 6.03% of them went down. 70.48% of the patients who had received antiviral therapy more than 3 months had their viral load lower than the low detectable limitation. When comparing the log of viral load between treated and untreated cohort, the mean value of the treated was obviously less than the untreated (P < 0.05). However,the result of drug resistance showed no obvious difference between the treated and untreated groups.
CONCLUSIONThe antiviral therapy being used in Guangxi region, had achieved obvious effect on the reconstruction of immune system and the suppression of viral replication in vivo under good adherence while the occurrence of drug-resistant HIV strain did not show obvious difference between treated and naive patient groups.

OBJECTIVETo design ABC damage variable and positioning system for acetabular fracture and explore the feasibility and clinical practical value of the system through the multi-center analysis of 1122 acetabular fractures.
METHODSAccording to acetabular three-column conception, and pelvic ring lesions damage direction caused by acetabular fracture domino effect and injury degree of proximal femur joint, it defined class A as any column acetabular fracture; class B as any two-column acetabular fracture; class C as front, dome and posterior mixture acetabular fracture. Lower case English letters a, m, p represented front, dome, posterior fracture, respectively. Acetabular damage variables: 1 was simple displaced fractures; 2 was comminuted fractures; 3 was compression fractures. Pelvic ring lesions damage variables: alpha was sacroiliac joints or sacroiliac fracture horizontal separation deflection; beta was sacroiliac joints or sacroiliac fracture vertical separation deflection; gamma was pubic symphysis separation/superior and inferior ramus of pubis fracture deflection; alpha beta gamma delta was compound floating damage. Proximal humerus joint damage variables: I was femoral head fracture; II was femoral neck fracture; II was intertrochanteric fractures of femur; IV was I to III compound fracture. The ABC damage variable positioning system for acetabular fracture was made up by the above-mentioned variables. The statistics from March 1997 to February 2010 showed 1122 cases acetabular fractures with 18 cases of double side acetabular fracture and 1140 cases of acetabular fractures. The pelvics anterior-posterior view, ilium and obturator oblique view, and 2/3D-CT materials were analyzed and researched.
RESULTSEach damage variables distribution situation in 1140 cases of acetabular fracture involved A in 237 cases (20.8%), B in 605 cases (53.1%), C in 298 cases (26.1%);front column fracture in 808 cases(70.9%), dome fracture in 507 cases (44.5%), posterior fracture in 1026 cases (90%). Acetabular variables: variabe 1 in 203 cases of simple displaced fracture (17.8%); variabe 2 in 516 cases of comminuted fracture(45.3%); variabe 3 in 421 cases of compression fracture (36.9%); 249 cases of pelvic ring lesions damage (21.8%), 75 cases femoral head fracture (6.6%); 18 cases of double side acetabular fracture and relative pelvic ring and proximal humerus joint variables (1.58%). Key part and curative effect elements of 1140 cases acetabular fracture: 507 cases of dome or posterior acetabular fracture (44.5%); 421 cases of compression fracture (36.9%); 249 cases of pelvic ring variables (21.8%); 75 cases of proximal humerus joint variables (6.6%); 486 cases of simple Aa/pl/2,Bapl/2 acetabular fracture (42.6% ).
CONCLUSIONCompression fracture, especially defected compression fracture, takes important part in acetabular damage variables, and also presents that acetabular fracture with pelvic ring and proximal femoral damage variables are not rare at all. The relationship of the acetabular fracture damage variables, and its percentage shows the key points and elements in clinical treatment: weight-bearing to dome accounts for 44.5%; compression to defects account for 36.9%, pelvic ring to float accounts for 21.8%; dome fracture to double side fracture account for 6.6%. The system has significant guiding effects on clinic in terms of evaluation of injury severity, anatomic localization, difficulty index, alternative strategy, operative approach, effect of treatment,and prognosis. And the most important thing is that the system creates the comparison of damage variables in same type of fracture and the communication of homo-language and explores a new method.
