Objective To evaluate the effects of C4-5 partial foraminotomy on reducing the occurrence of C5 palsy after posterior cervical decompression surgery. Methods A total of 127 patients (male 62, female 65) underwent the cervical decompression surgery with lateral cervical mass screw insertion between January 2011 and December 2015 were retrospectively analyzed. In these patients sixty-one cases (Group A) underwent the posterior laminectomy with lateral cervical mass screw insertion, while 66 cases (Group B) received posterior laminectomy with lateral cervical mass screw insertion, combined with partial C4/5 foraminotomy at C4-5 level. The clinical data, radiographic parameters and the occurrence of C5 palsy were assessed in two groups of patients. Results There was no significant difference in JOA recovery rate and change of cervical curvature index between preoperation and postoperation in each group (P>0.05). Postoperative C5 palsy occurred in 11 cases (18.03%) in group A and 3 cases (4.05%) in group B. The difference in the incidence of C5 palsy was significant between the two groups (P=0.022). Conclusion The cervical decompression surgery can improve the function of the spinal cord effectively. C4-5 partial foraminotomy after cervical decompression surgery is effective for preventing C5 palsy.

OBJECTIVETo investigate the influences of varying lingual traction forces on the space-closing speed in a typodont model.

METHODSForty-two Angle Class I standard typodont models of bimaxillary teeth protrusion were divided into 7 equal groups. Four regions of the model were paired to groups, and in the odd-numbered models, the top left and bottom left regions served as the experimental group and the top right and bottom right regions as the control group; in the even-numbered models, the regions in the model were grouped oppositely. In the experimental group, the space was closed by niti wire extension spring in the buccal ridge combined with lingual elastic traction of 0, 5, 10, 15, 20, 25 and 30 g. In the control group, the space was closed by exclusive niti wire extension spring in the buccal ridge. The space-closing speed were analyzed in all the groups.

RESULTSThe space-closing speed was significantly lower in the control group than in the experimental groups with lingual traction forces of 5, 10, 15, 20 and 25 g (P<0.05), but a traction force of 30 g resulted in a significantly lower speed than that in the control group (P<0.05). The space closing speed was the greatest in the experimental group with a traction force of 15 g (P<0.05).

CONCLUSIONNiti wire extension spring in the buccal ridge combined with lingual elastic traction results in faster space-closing speed than traditional exclusive niti wire extension spring. The speed is the fastest by applying 15 g lingual traction, which is also associated with the lowest slip resistance.

OBJECTIVETo explore the important role of the terminal residues containing sialic acid (SA) in Campylobacter jejuni (CJ) lipopolysaccharide (LPS) as the critical antigen to induce nerve damage, and also to identify immunopathological evidence for the hypothesis of molecular mimicry and cross-immunity between CJ LPS and gangliosides.

METHODSA mutant of Pen O:19 CJ with neuB1 gene inactivated and LPS outer core terminal residues losing SA was to be constructed. PCR and RT-PCR were used to confirm the mutant. Capability of CJ LPS binding to cholera toxin B subunit (CTB) was tested. Guinea pigs were systematically immunized with LPS of the wild and the mutant strains, respectively. Titers of anti-LPS and anti-ganglioside GM(1) IgG antibodies in sera of immunized guinea pigs were detected by ELISA. Pathological study for sciatic nerves of both Guinea pigs either immunized systematically or perineural injection with their immunized serum was finished.

RESULTS(1) The mutant of CJ O:19 strain with inactivated neuB1 gene was successfully constructed and lost transcriptional activity of neuB1 gene in the mutant strain was confirmed by PCR and RT-PCR. SA was well demonstrated by both acidic ninhydrin reaction and periodate-resorcinol reaction in the LPS of wild strain but not in the mutant LPS; (2) Compared with the titers before immunization, the titers of anti-GM(1) IgG antibody increased in sera of guinea pigs immunized with LPS of the wild strain. However there were no detectable anti-GM(1) IgG antibody in sera of the animals immunized with mutant LPS and PBS. (3) The incidence of pathological fibers of sciatic nerves in wild CJ LPS group (17.3%) was significantly higher than the mutant CJ LPS group (chi(2) = 125, P < 0.01); the difference between the mutant CJ LPS group and control group was not statistically significant (chi(2) = 1.633, P > 0.05). (4) After perineural injection with immunized serum, the incidence of pathological fibers of sciatic nerves in wild strain group (67.8%) was also significantly higher than the incidence of mutant group (P < 0.01).

CONCLUSIONA mutant of CJ O:19 strain neuB1 gene inactivated and SA component of terminal structure of LPS lost was successfully constructed. And it no longer expressed SA component which is the normal terminal structure of LPS in wild strain. The capability of the wild strain to induce increased titers of anti-GM(1) antibody and immune-mediated nerve damage was simultaneously lost for the mutant strain. It could be a strong immunopathologic evidence to identify the molecular mimicry hypothesis between CJ LPS and ganglioside epitope in nerve on the pathogenesis of CJ related GBS. The terminal residues containing SA should be as the basic GM1-like structure in CJ LPS.

OBJECTIVETo probe into the clinical effect of needle-pricking therapy for treatment of polycystic ovarial syndrome.

METHODSOne hondred and twenty-one cases of polycystic ovarial syndrome were divided into a needle-pricking therapy group of 61 cases and a medication group of 60 cases with randomized and controlled method. The needle-pricking therapy group were treated by needle-pricking therapy at sacral plexus stimulating points on both sides of the spine and lateral points of Dazhui (CV 14), and the medication group by oral administration of domiphen and intramuscular injection of chorionic gonadotropin (HCG). Levels of hormones and symptoms in the patients before treatment, after treatment of 3 cycles and at the sixth cycle after treatment were investigated.

RESULTSAfter treatment of 3 cycles, the level of hormone and B type ultrasound examination were significantly improved in the two groups (P < 0.01). At the sixth cycle after treatment, the conditions of the patients in the medication group were returned to the original levels before treatment, while the conditions in the needle-pricking therapy group still kept at the post-therapeutic level, and their menstruation and ovulation restored to normal state, and the ovulation mucosa and the pregnancy rate were significantly higher than those in the medication group (all P < 0.01).

CONCLUSIONNeedle-pricking therapy has obvious effect on polycystic ovarial syndrome, and has a good long-term therapeutic effect.

OBJECTIVETo evaluate the influence of Shenfu Injection (SHF) on the quality of life of patients with advanced non-small cell lung cancer (NSCLC) receiving chemotherapy.

METHODSA total of 133 patients with NSCLC receiving at least two cycles of chemotherapy with taxol plus cisplatin (TP)/vinorelbine plus cisplatin (NP) or gemcitabine plus cisplatin (GP) were randomized into SHF pre-treatment group (with SHF given only in the first cycle) and SHF post-treatment group (with SHF given only in the second cycle). The Quality of Life Questionnaire-Core 30 (QLQ-C30) and the Functional Living Index-Cancer (FLIC) were used to evaluate the quality of life of the patients after the treatments.

RESULTSBoth of the groups showed improved quality of life after the treatments (P<0.01), but the improvements were more obvious in SHF pre-treatment group (P<0.05). SHF showed favorable effects in relieving such adverse effects as fatigue, nausea, vomiting and diarrhea associated with the chemotherapy.

CONCLUSIONSHF can improve the quality of life in NSCLC patients receiving chemotherapies.

OBJECTIVETo explore the impact of prenatal exposure to lipopolysaccharide on renin-angiotensin system of offspring rats.

METHODSSix pregnant SD rats were randomly divided into 2 groups. The rats in the lipopolysaccharide (LPS) group were treated with LPS 0.79 mg/kg (i.p.) on the 8th, 10th and 12th day of gestation, and rats in the control group were treated with saline at the same time points. The blood pressure of offspring rats was measured by the tail cuff method. Protein expression of Angiotensin II (AngII) in thoracic aorta vessel was determined by immunohistochemistry. Protein expressions of AngII type 1 and type 2 receptor in thoracic aorta vessel were detected by Western blot.

RESULTSBlood pressure of 12-week-old offspring rats of LPS group was significantly higher than that of 12-week-old offspring rats of control group (P < 0.01). The protein expression of AngII and AngII type 1 receptor in thoracic aorta vessel were significantly higher while protein expression of AngII type 2 receptor was lower in 15-week-old offspring rats of LPS group than in control group, resulting in a significant increase in the ratio of AngII type 1 receptor/AngII type 2 receptor in the aorta at 15-week-old of offspring rats than in 15-week-old offspring rats of control group (P < 0.01).

CONCLUSIONPrenatal lipopolysaccharide exposure results vascular renin-angiotensin system dysfunction, which may play an important role on the pathogenesis of hypertension development in offspring rats.

OBJECTIVETo investigate the efficacy and safety of antiviral treatment in patients with hepatitis C virus (HCV) infection and decompensated cirrhosis and determine the effects of virological response on long-term prognosis.

METHODSSixty-six consecutive,interferon (IFN)-na(i)ve patients with HCV infection and decompensated cirrhosis were enrolled in this prospective study. All patients were given a 48-to 72-week course of IFN plus ribavirin (RBV) combined therapy,with a low accelerating dosage regimen using either:pegylated (PEG)-IFNa-2b at 1.0-1.5 mug/kg/week,PEG-IFNa-2a at 90-180 mug,or standard IFN-a-2b at 3MU,every other day.RBV was given at 800 to 1000 mg/day. All patients were routinely monitored for adverse drug reactions and virological response.Effects of treatments on patient survival were assessed by Kaplan-Meier analysis.

RESULTSAt the end of treatment,74.2% of patients were HCV RNA-negative,with 45.5% having achieved sustained virological response and 28.8% having relapsed;the remaining 25.7% of patients showed non-virological response (NVR). Among the patients with HCV genotype 1, 65.9% achieved end-of-treatment virological response (ETVR) and 34.1% achieved SVR;among the patients with HCV genotype 2,90.9% achieved ETVR and 68.2% achieved SVR. The positive and negative predictive values of early virological response (EVR) for ETVR were 95.7% and 75.0% respectively, and for SVR were 65.2% and 100% respectively. Compared with baseline,patients who achieved ETVR had better liver function,as evidenced by changes in levels of total bilirubin,alanine aminotransferase and albumin,as well as prothrombin activity and Child-Pugh score (t =4.564,11.486,2.303,2.699,3.694 respectively, all P less than 0.05).Compared with the NVR patients, the ETVR patients had lower risk of hepatic decompensation and hepatocellular carcinoma, and had improved survival (x2=18.756,6.992,7.580, respectively, all P less than 0.05).Twelve (18.2%) patients experienced serious adverse events,with 10 requiring premature treatment withdrawal and 2 dying.

CONCLUSIONAntiviral treatment for patients with HCV infection and decompensated cirrhosis using interferon in a low accelerating dosage regimen in combination with ribavirin is feasible.Patients who achieved ETVR had significantly improved long-term prognosis.

OBJECTIVETo evaluate the clinical efficacy of Jianpi Liqi Yiliu Formula (JLYF) combined with cytokine-induced killer (CIK) cells for treating patients with advanced hepatocellular carcinoma (HCC).

METHODSBetween January 2011 and January 2014, 60 advanced HCC patients were enrolled in this study, who were assigned to the treatment group and the control group according to their willingness for taking JLYF, 30 cases in each group. All patients received CIK cell treatment: 1 x 10⁹-3 x 10⁹ each time, by intravenous dripping from the 1st day to the 3rd day, once per day. Besides, patients in the treatment group took JLYF decoction, while those in the control group took Chinese medical decoction by syndrome typing. All patients received treatment of at least two cycles. The time to progression (TTP) , overall survival (OS), disease control rate (DCR), performance status scale (PS), Child-Pugh scale, and adverse reactions were observed, and subgroup analyzed.

RESULTSTo May 31, 2014, all patients reached the clinical endpoint. TTP was 3.5 months (95% Cl: 3.30-4.10) in the treatment group, better than that (2.5 months, 95% CI: 2.32-2.68) of the control group (P < 0.05). DCR was 36.7% in the treatment group and 30.0% in the control group (P > 0.05). OS was 5.2 months (95% CI: 4.53-5.87) in the treatment group and 4.6 months (95% CI: 4.06-5.14) in the control group (P > 0.05). The PS scale was 1.60 ± 0.10 after treatment, lower than that (1.80 ± 0.09) before treatment in the treatment group (P < 0.05). When the PS scale was 0-2 or Child-Pugh scale was class A, TTP was longer in the treatment group than in the control group (P < 0.05). No adverse reaction occurred in the two groups during the treatment course.

CONCLUSIONSThe combination of JLYF with ClK cell treatment could prolong advanced HCC patients' TTP, improve PS scale, as compared with syndrome typed Chinese medical decoction treatment group. Besides, when the PS scale was 0-2 or Child-Pugh scale was class A, it was a better treatment program for advanced HCC patients.
