OBJECTIVETo evaluate the effectiveness of manual therapy and traction for lumbar disc herniation and analyze the current status of this kind of randomized clinical trial (RCT).

METHODSDatabase of CNKI, VIP, WANFANG, PubMed and OVID were searched. Some relevant journals were manually retrieved. A total of 2 874 literatures on manual therapy and traction for lumbar disc herniation were collected, of which 17 articles met the inclusion criteria. The Jadad score scale was used to evaluate the quality,and RevMan5.0 was used for meta-analysis of literatures.

RESULTSThe results of the meta-analysis of all trials involved were as followed:the combined effect of the effective rate was RR = 1.10, 95% CI [1.06, 1.14], the combined effect of the cure rate was RR = 1.36, 95% CI [1.21,1.52], the combined effect of the VAS was RR = 1.37, 95% CI [1.28, 1.45], the combined effect of the JOA was RR = 4.75, 95% CI [4.40, 5.09].

CONCLUSIONThe overall quality of the current RCT researches about manual therapy for lumbar disc herniation was lower,and did not support the conclusion that manual therapy was more effective than traction for lumbar disc herniation.

Objective:To study the genetic characteristics and genetic evolution of echovirus 30 (ECHO30) isolates in Yunnan Province, China.Methods:Virus isolation was performed on nucleic acid-positive samples for hand, foot, and mouth disease pathogen surveillance in Yunnan Province, and VP1 gene sequencing was performed. The sequences of eight ECHO30 isolates from Yunnan Province and the gene sequences of the VP1 region of the ECHO30 reference strain downloaded from GenBank were compared and analyzed using MEGA 5.0 software, and then a phylogenetic tree was constructed to measure the homology of nucleotides and amino acids between the isolates.Results:The ECHO30 virus was distributed in Wenshan, Qujing, Chuxiong, and Kunming in Yunnan Province. The ECHO30 virus was relatively common in Wenshan. ECHO30 isolates belonged to the H2 subtype of the H genotype, which was close to the local reference strain LC120939 in Yunnan Province. On the VP1 gene at site 5, the amino acid change ratio was more active, the amino acids were diverse, and mutations also occurred at sites 54, 156, 258, and so on. Nucleotide and amino acid homology were 84.0% - 100.0% and 98.4% - 100.0%, respectively.Conclusions:ECHO30 isolates from Yunnan Province have certain geographical characteristics and belong to H2 of the H genotype. The nucleotide differences in virus sequences among subtypes are small and have a close genetic relationship.

Peroxisome proliferator-activated receptordelta (PPARdelta), as a downstream target of adenomatous polyposis coli (APC) signaling pathway, has been presumed to play some roles in colorectal carcinogenesis. However, the exact role of PPARdelta in colorectal cancer remains unclear. An HIV-1-based lentivirus packaging system was used for the construction of a lentiviral vector (lentivector) mediating RNA interference against PPARB. The direct sequencing demonstrated that the resulting lentivector containing the short-hairpin RNA expression cassette specifically targeting PPARdelta (sh-PPARdelta) was successfully constructed, and designated as pLVshPPARdelta. The control vector was designated as pLVControl. After the transduction, we observed highly efficient transduction (> 90%) of lentivirus in KM12C cells by fluorescent microscopy and fluorescence-activated cell sorting. Quantitative RT-PCR showed that pLVshPPARdelta lentivirus reduced PPARdelta mRNA expression by about 70.0% in KM12C cells as compared with that of the untreated cells (P < 0.05), while pLVControl had no significant effect on the PPARdelta mRNA level (P > 0.05). Western blot revealed an obvious reduction of PPARdelta protein expression in pLVshPPARdelta treated cells and showed no obvious difference between the control group and the untreated group. The results demonstrated that the lentivector mediating RNAi against PPARdelta was successfully constructed, which could stably knock down the PPARdelta expression in KM12C cells. This study finally provided a new cell model for the study of PPARdelta's function in colorectal cancer.

Objective:To investigate the predominant types of enteroviruses and the characteristics of the VP1 gene of coxsackievirus A4 (CVA4) causing hand, foot and mouth disease (HFMD) in Yunnan Province from 2018 to 2020.Methods:Throat swab and stool samples were collected from HFMD cases and tested by real-time quantitative PCR for nucleic acid detection. The samples positive for enterovirus nucleic acids were used for viral isolation and sent to the National Center for Disease Control and Prevention. The VP1 gene of the isolated strains was sequenced and analyzed.Results:From 2018 to 2020, a total of 21 757 HFMD samples were collected, 16 457 (75.64%) of which were positive for enteroviruses. Altogether 533 strains were isolated from 4 114 positive samples that were selected for viral isolation, including 89 strains of enterovirus 71 (EVA71, 16.70%), 180 strains of coxsackievirus A16 (CVA16, 33.77%), 76 strains of CVA10 (14.26%), 118 strains of CVA6 (22.14%), 26 strains of CVA4 (4.88%) and 44 strains of other types (8.26%). HFMD occurred mainly in children under five years old with higher incidence in males than in females (1.35∶1). The incidence of HFMD reached the peak in the second and third quarters. In Yunnan Province, CVA4 mainly circulated in Qujing and Kunming, and was sporadically detected in Wenshan and Honghe. The VP1 gene was 915 bp in length. Twenty-six CVA4 strains belonged to C2 subtype, which were genetically far from the prototype strain AY421762-HighPoint. Mutations in the VP1 gene were found at multiple sites including 18, 23, 34, 102, 148, 164, 200, 262, 174, 275, 285 and 303. These strains showed 80.4%-99.0% homology in nucleotide sequence and 95.6%-99.0% in amino acid sequence. Nucleotide mutations were mostly synonymous mutations.Conclusions:CVA16, CVA6, EVA71 and CVA10 were the predominant enteroviruses causing HFMD in Yunnan Province from 2018 to 2020. The prevalence of CVA4 was also worthy of attention. CVA4 isolates in Yunnan Province belonged to C2 subtype, mainly circulating in the east and southeast of Yunnan Province and gradually becoming a cocirculating predominant strain. Long-term dynamic monitoring would be of great public health significance for improving the sensitivity of HFMD early warning.

Objective To investigate the changes of HBV markers in patients with HBeAg positive chronic hepatitis B(CHB) after a large number of blood transfusion treatment.Methods 26 patients with chronic HBV that were treated massive blood transfusion in 24h were collected from Jan 1,2015 to Jan 1,2016.The HBV serum markers and HBV-DNA were measured and compared before and after treatment.Results The HBsAg,anti-HBs and anti-HBc concentration in first day after treatment were different compared with before treatment(t=2.681,4.753 and 5.116,all P<0.01).The HBsAg,anti-HBs and anti-HBc concentration in third day after treatment exist differences compared with before treatment(t=1.681, 2.209 and 3.118,all P<0.05).The difference still exist in the seventh day after treatment compared with before treatment with only anti-HBc concentration(t=2.463,P<0.05).There was not difference of HBeAg and HBV-DNA before and after blood transfusion in patients(t=0~1.132,P>0.05).After transfusionthe concentration of HBsAg in the fifth day was the lowest concentration as 0.17±0.03 IU/ml,the seventh day rose to 387.50±31.89 IU/ml,reaching the highest value,and the concentration of HBsAb decreased gradually to minimum at the seventh day that was 1.51±5.98 mIU/mmol,and the concentrations of HBeAg,HBeAb and HBcAb had no obvious change.Conclusion The HBsAg,anti-HBs and anti-HBc could be changed in patients with HBeAg positive CHB after massive transfusion therapy in short term.HBeAg and HBV-DNA were not affected by transfusion therapy.

OBJECTIVETo observe long-term outcomes of patients with invasive giant prolactinomas (IGPs) treated with bromocriptine followed by comprehensive treatments.

METHODSThirty-four patients met the criteria of IGPs were treated with bromocriptine initially. Among of them, 11 had radiotherapy at the same time. During the treatments, transsphenoidal surgery or/and Gamma Knife were considered to apply to the patients according to the location, shrinkage of residual tumors and resistance of bromocriptine. Small dosage of bromocriptine was kept after operation.

RESULTSThe average follow-up duration is 33.6 months. Thirty-three patients obtained significant improvement, but one failed recovery of vision due to side-injury by radiotherapy. Tumor volume on magnetic resonance imaging (MRI) was decreased on average by 91.4%, PRL by 97.1%. The number of patients with low testosterone level restored from 17 to 6 and hypoadrenalism from 10 to 6 after combined treatment with priority of medical therapy. Rhinorrhea occurred in 2 cases, 1 restored in two weeks, 1 had transsphenoidal combined with transcranial surgery to remove the tumor and repair the fistula.4 had resistance to bromocriptine to some extend.

CONCLUSIONSDopamine agonist medications are effective as a first-line therapy for IGPs. In some patients treated by bromocriptine only, the tumor may disappear on MRI. Combined with surgery and Gamma Knife, the duration of treatment could be shortened and the dosage may be minimized, but using radiotherapy should be cautions.

OBJECTIVETo evaluate the effect on pre-exposure prophylaxis (PrEP) to prevent HIV infection in high risk populations.

METHODSA computerized literature searching had been carried out in PubMed, EMbase, Ovid, Web of Science, Science Direct, Wanfang, Tsinghua Tongfang database and related websites to collect relevant papers (from establishment to June 2012) with the key words of pre-exposure prophylaxis, HIV, AIDS, high risk populations, relative risk, reduction. All randomized controlled trials (RCT) papers about using single or compound antiretroviral drugs (ARVs) orally or topically before HIV exposure or during HIV exposure in high risk populations were enrolled. Meta-analysis was conducted using Stata 10.0 to calculate the pooled RR value (95%CI). Consistency test was performed and publication bias was evaluated.

RESULTSFinally 5 RCT papers were enrolled, including 10 271 persons who were at high risk of HIV infection. The number of the experimental group was 5929, among which 116(1.96%) became infected. The number of the control group was 4342, among which 201(4.63%) became infected. Meta-analysis showed that the pooled relative risk (RR) and 95%CI was 0.49 (0.39 - 0.61), P < 0.05, indicating that the persons in experimental group had a 0.49 times lower risk of HIV infected, as compared with the control group. Publication bias analysis revealed a symmetry funnel plot. The fail-safe number was 825.

CONCLUSIONPrEP was an effective and safe protection measure to reduce HIV infection in high risk populations.

OBJECTIVETo evaluate the living donor selection, donor hepatectomy technique, and surgical complication in living donor liver transplantation.

METHODSFrom June 2007 to July 2008, 74 consecutive cases living donor hepatectomy were performed by the same surgical team. Seventy-four donors (64 males and 10 females) with a mean age of 29.2 years old passed the donor liver assessment and evaluation program successfully. The hepatectomy procedure types contained right liver resection (n = 72), of which 27 cases harvested the middle hepatic vein and 45 cases not, left liver resection contain middle hepatic vein (n = 1) and left lateral resection (n = 1).

RESULTSOf all the donors, operation time was (6.5 +/- 6.2) hours, the mean blood loss was 300 ml (100 - 500 ml) and didn't accept foreign blood transfusion. The maximum alanine aminotransferase (ALT) level was (229.5 +/- 108.6) U/L, the ALT returned to normal time was (12.7 +/- 4.8) d, the maximum total bilirubin (TB) level was (78.7 +/- 44.3) micromol/L, the TB returned to normal time was (8.8 +/- 2.7) d, and the mean hospital stay time was 14 days (7 - 28 d). The complications included bile leak (n = 1), cut surface hemorrhage (n = 1) and anaphylactoid purpura (n = 1). All the donors returned to normal work and life finally.

CONCLUSIONSPrecisely evaluating donor blood vascular and biliary anatomy before operation, keeping the blood vascular and bile duct integrity during operation and monitoring complication to solve it immediately after operation is crucial to ensure donor safety and recovering successfully.
