ABSTRACT

The editorial group of the clinical practice guideline for postmenopausal osteoporosis(PMOP) with traditional Chinese medicine(TCM)(hereinafter referred to as "guideline") is composed of experts specialized in TCM orthopedics, TCM gynecology, clinical epidemiology, etc. The guideline was formulated through registration, collection and selection of clinical issues/outcome indicators, evidence retrieval and screening, preparation of systematic reviews, evaluation of evidence quality, formation of recommendations, drafting, and peer review. The syndromes and treatment of PMOP are elaborated in detail. Specifically, Liuwei Dihuang Pills and Zuogui Pills are recommended for PMOP with Yin deficiency in the liver and kidney, Qing'e Pills for PMOP with kidney deficiency and blood stasis, Yougui Pills and Jingui Shenqi Pills for PMOP with Yang deficiency in the spleen and kidney, and Er'xian Decoction for PMOP with Yin and Yang deficiency in the kidney. In addition, Duhuo Jisheng Decoction can be used to relieve pain. The commonly used Chinese patent medicines include Xianling Gubao Capsules, Qianggu Capsules, Jintiange Capsules, Gushukang Capsules, Hugu Capsules, Jinwu Gutong Capsules, and Guyuling Capsules. Acupuncture and moxibustion are also effective approaches for PMOP. The rehabilitation and daily management were carried out by exercise therapies such as Baduanjin(eight-section brocade), Wuqinxi(five-animal exercises), and Taijiquan(Tai Chi), Chinese medicine diet, health education, and fall prevention. The promotion and application of this guideline will facilitate the implementation of TCM prevention and treatment of PMOP, ensure the quality of life of PMOP patients, provide effective and safe TCM treatment measures for PMOP, and reduce the risk of fracture complications.

ABSTRACT

BACKGROUND@#Delivery room resuscitation assists preterm infants, especially extremely preterm infants (EPI) and extremely low birth weight infants (ELBWI), in breathing support, while it potentially exerts a negative impact on the lungs and outcomes of preterm infants. This study aimed to assess delivery room resuscitation and discharge outcomes of EPI and ELBWI in China.@*METHODS@#The clinical data of EPI (gestational age [GA] <28 weeks) and ELBWI (birth weight [BW] <1000 g), admitted within 72 h of birth in 33 neonatal intensive care units from five provinces and cities in North China between 2017 and 2018, were analyzed. The primary outcomes were delivery room resuscitation and risk factors for delivery room intubation (DRI). The secondary outcomes were survival rates, incidence of bronchopulmonary dysplasia (BPD), and risk factors for BPD.@*RESULTS@#A cohort of 952 preterm infants were enrolled. The incidence of DRI, chest compressions, and administration of epinephrine was 55.9% (532/952), 12.5% (119/952), and 7.0% (67/952), respectively. Multivariate analysis revealed that the risk factors for DRI were GA <28 weeks (odds ratio [OR], 3.147; 95% confidence interval [CI], 2.082-4.755), BW <1000 g (OR, 2.240; 95% CI, 1.606-3.125), and antepartum infection (OR, 1.429; 95% CI, 1.044-1.956). The survival rate was 65.9% (627/952) and was dependent on GA. The rate of BPD was 29.3% (181/627). Multivariate analysis showed that the risk factors for BPD were male (OR, 1.603; 95% CI, 1.061-2.424), DRI (OR, 2.094; 95% CI, 1.328-3.303), respiratory distress syndrome exposed to ≥2 doses of pulmonary surfactants (PS; OR, 2.700; 95% CI, 1.679-4.343), and mechanical ventilation ≥7 days (OR, 4.358; 95% CI, 2.777-6.837). However, a larger BW (OR, 0.998; 95% CI, 0.996-0.999), antenatal steroid (OR, 0.577; 95% CI, 0.379-0.880), and PS use in the delivery room (OR, 0.273; 95% CI, 0.160-0.467) were preventive factors for BPD (all P < 0.05).@*CONCLUSION@#Improving delivery room resuscitation and management of respiratory complications are imperative during early management of the health of EPI and ELBWI.

ABSTRACT

Objective To investigate the clinical effect of plasma exchange(PE)combined with plasma bilirubin ad-sorption(PBA)in the treatment of liver failure associated with hepatitis B virus(HBV). Methods A total of 75 patients with HBV related liver failure were selected from May 2014 to May 2016 in the People's Hospital of Guangxi Zhuang Autonomous Region. The patients were divided into PE group,PBA group and PE combined PBA(PE + PBA)group according to their will, 25 cases in each group. The levels of serum alanine aminotransferase(ALT),total bilirubin(TBIL),albumin(ALB),prothrom-bin time(PT),prothrombin activity(PTA),serum creatinine(SCr)and blood ammonia were compared among the three groups before and after treatment,and the adverse reactions were observed. Results There was no significant difference in serum ALT,TBIL,ALB and SCr levels among the three groups before treatment(P > 0. 05). The levels of serum ALT,TBIL and SCr after treatment were significantly lower than those before treatment in the three groups(P < 0. 05). The level of serum ALB af-ter treatment was significantly higher than that before treatment in the PE group and the PE + PBA group(P < 0. 05),but the level of serum ALB after treatment was significantly lower than that before treatment in the PBA group (P < 0. 05). There was no significant difference in serum ALT,TBIL and SCr levels among the three groups after treatment(P > 0. 05). The serum ALB levels in the PE group and the PE + PBA group was significantly higher than that in the PBA group after treatment(P <0. 05). There was no significant difference in serum ALB level between the PE group and the PE + PBA group after treatment (P > 0. 05). There was no significant difference in the PT,PTA and blood ammonia level among the three groups before treat-ment(P > 0. 05). Compared with before treatment,the PT shortened significantly after treatment,the PTA increased significant-ly,and the blood ammonia level decreased significantly in the three groups(P < 0. 05). Compared with the PBA group,the PT shortened significantly,the PTA increased significantly,and the blood ammonia level decreased significantly in the PE group and the PE + PBA group after treatment(P < 0. 05). There was no significant difference in PT,PTA and blood ammonia level between the PE group and the PE + PBA group after treatment(P > 0. 05). The plasma consumption of patients in the PE group and the PE + PBA group was(2908. 11 ± 287. 91)and(1107. 24 ± 213. 67)mL respectively,the plasma consumption in the PE + PBA group was significantly less than that in the PE group(t = 23. 782,P < 0. 05). The treatment time of patients in the PE group,the PBA group and the PE + PBA group was(2. 90 ± 0. 87),(3. 02 ± 0. 77),(3. 22 ± 0. 69)h respectively;there was no significant difference in the treatment time among the three groups(F = 1. 881,P > 0. 05). The total effective rate in the PE group,the PBA group and the PE + PBA group was 64. 0%(16 / 25),56. 0%(14 / 25),64. 0%(16 / 25),respectively;there was no significant difference in the total effective rate among the three groups(χ2 = 7. 281,P > 0. 05). The incidence of eryth-ra,chill and rigor,numbness and convulsion,infection and errhysis in the PE group was 32. 0%(8 / 25),28. 0%(7 / 25), 16. 0%(4 / 25),8. 0%(2 / 25),8. 0%(2 / 25),respectively. The incidence of erythra,chill and rigor,numbness and convul-sion,infection and errhysis in the PBA group was 16. 0%(4 / 25),16. 0%(4 / 25),12. 0%(3 / 25),4. 0%(1 / 25),4. 0%(1 /25),respectively. The incidence of erythra,chill and rigor,numbness and convulsion,infection and errhysis in the PE + PBA group was 20. 0%(5 / 25),20. 0%(5 / 25),12. 0%(3 / 25),4. 0%(1 / 25)and 4. 0%(1 / 25),respectively. The incidence of erythra,chill and rigor,numbness and convulsion,infection and errhysis in the PBA group and the PE + PBA group was signifi-cantly lower than that in the PE group(P < 0. 05). There was no significant difference in the incidence of erythra,chill and rig-or,numbness and convulsion,infection and errhysis between the PBA group and the PE + PBA group(P > 0. 05). Conclusion PE combined with PBA is effective,safe and feasible in the treatment of HBV related liver failure,and it can reduce plasma consumption.

ABSTRACT

<p><b>Objective</b>To study the clinical effect endoscopic realignment with drainage via a peel-away sheath in the treatment of urethral rupture.</p><p><b>METHODS</b>We treated 21 urethral rupture patients by endoscopic realignment with drainage via a peel-away sheath using normal saline for irrigation under the normal nephroscope or Li Xun nephroscope, followed by analysis of the clinical results.</p><p><b>RESULTS</b>The operation was successfully accomplished in 20 cases but failed in 1 and none experienced urinary extravasation. In the 14 cases of bulbar urethral rupture, the mean operation time was (5.1±1.6) min and the mean Foley catheter indwelling time was (26.0±5.1) d. Urethral stricture developed in 57.1% (8/14) of the cases after catheter removal, of which 1 was cured by internal urethrotomy and the other 7 by urethral sound dilation, with an average maximum urinary flow rate of (18.8±1.8) ml/s at 12 months after operation. In the 6 cases of posterior urethral rupture, the mean operation time was (15.8±7.5) min and the mean Foley catheter indwelling time was 8 weeks. Urethral stricture developed in all the 6 cases after catheter removal, of which 3 cases were cured by urethral dilation, 1 by internal urethrotomy, and 2 by open urethroplasty. The average maxium urinary flow rate of the 4 cases exempt from open surgery was (17.9±1.9) ml/s at 12 months after operation.</p><p><b>CONCLUSIONS</b>Endoscopic realignment with drainage via a peel-away sheath can keep the operative field clear, avoid intraoperative rinse extravasation, shorten the operation time, improve the operation success rate, and achieve satisfactory early clinical outcomes in the treatment of either bulbar or posterior urethral rupture.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the change of lymphocyte subsets before and after chemotherapy in colorectal carcinoma patients.</p><p><b>METHODS</b>Twenty-one peripheral blood lymphocyte subsets from 62 colorectal carcinoma patients before and after FOLFOX4(including oxaliplatin, 5-fluorouracil and leucovorin) , FOLFRI(including irinotecan, 5-fluorouracil and leucovorin) , or XELOX(including oxaliplatin and capecitabine) regimen chemotherapy were examined by flow cytometry.The differences of these lymphocyte subsets were analyzed.</p><p><b>RESULTS</b>After chemotherapy, the percentages of CD3(+), CD3(+)CD8(+), CD29(+), CD4(+)CD29(+), and CD4(+)CD25(+) cells in peripheral blood of colorectal carcinoma patients increased significantly, while the percentages of CD19(+) and human leukocyte antigen(locus) DR(HLA-DR) (+) cells decreased significantly(P<0.05) .The results of subgroup analysis showed that the patients' CD3(+)CD8(+) and CD4(+)CD25(+) cells increased significantly, CD19(+) and HLA-DR(+) cells decreased significantly after FOLFOX4 regimen chemotherapy(P<0.05) ;CD3(+)CD8(+) cells increased significantly and CD19(+) cells decreased significantly after XELOX regimen chemotherapy(P<0.05) ;while after FOLFRI regimen chemotherapy, there were no significant changes in all 21 lymphocyte subsets(P>0.05) . CD3(+), CD3(+)CD8(+), memory T lymphoctye(45RO(+)) , and CD4(+)CD45RO(+) cells increased significantly(P<0.05) in patients who received no more than 4 cycles of chemotherapy. However, in patients that received 5 to 8 cycles and more than 9 cycles chemotherapy, we only found significant decrease of HLADR(+) cells and significant increase of CD29(+) cells, respectively(P<0.05) .</p><p><b>CONCLUSIONS</b>The humoral immunity is attenuated after chemotherapy in colorectal carcinoma patients. FOLFOX4 may suppress the cellular immunity.Chemotherapy that is less than 4 cycles will strengthens the cellular immunity by modulating body immunity arrangement;however, along with the increase of chemotherapy cycles, the cellular immunity gradually declines in these patients.</p>

ABSTRACT

Anterior megalophthalmos (AM) is an uncommon developmental anomaly of the anterior segment of the eye with a constellation of findings that includes enlarged cornea, deep anterior chamber, posterior positioning of the iris and lens, iris stroma atrophy, hypoplasia of iris dilator, pupil displacement, large capsular bag, lens subluxation, prematurely cataract and the tendency to retinal detachment. AM, especially when symptoms are mild, is not an easy disease to diagnose. We present 3 AM cases that were misdiagnosed as congenital cataract with weak zonule and megalocornea. Intraocular lenses (IOLs) dislocated after standard cataract surgeries and subsequent surgery (replacing the dislocated IOLs with iris-claw intraocular lenses) achieved satisfactory outcome. Although rare, AM should be included in the differential diagnosis of enlarged cornea and we recommend implanting Artisan lens in AM patients.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the antitumor effect of natural killer (NK) cells on human colorectal cancer cells HT-29 in vitro by blocking transforming growth factor-β (TGF-β) signaling in NK cells transfected with vector containing dominant negative TGF-β type 2 receptor (DNTβR2).</p><p><b>METHODS</b>TGF-β1 was added at the final concentration of 10 ng/ml for HT-29 cells. Primary NK cells were transfected with recombinant plasmid pIRES2-AcGFP-DNTβR2 and control plasmid pIRES2-AcGFP using Amaxa Nucleofector technology respectively. The cytotoxicity of these two types of NK cells to HT-29 cells was detected and analyzed by cell counting kit-8.</p><p><b>RESULTS</b>The transfection efficiency of primary NK cells was 18.85% for the plasmid pIRES2-AcGFP-DNTβR2 and 35.28% for the control plasmid pIRES2-AcGFP. The expression of DNTβR2 in NK cells was confirmed by Western blotting and RT-PCR. Primary NK cells displayed significantly lower cytotoxicity against HT-29 cells incubated with TGF-β1 than that without TGF-β1 (effect-target cell ratio 10:1,14.40%∓ 2.00% vs. 26.14% ∓ 2.50%, P > 0.05; effect-target cell ratio 20:1, 19.18% ∓ 2.49% vs. 40.81% ∓ 3.50%, P > 0.05). The cytotoxicity of NK cells transfected with DNTβR2 vector was significantly higher than that with control vector against HT-29 cells cultured with 10 ng/ml TGF-β1 (effect-target cell ratio 10:1, 21.17% ∓ 2.49% vs. 11.48% ∓ 1.11% ,P > 0.05; and effect-target cell ratio 20:1, 35.30% ∓ 3.78% vs. 17.19% ∓ 2.29%, P > 0.05).</p><p><b>CONCLUSION</b>NK cells transfected with DNTβR2 vector show better antitumor effect, which may provide new method for NK-based adoptive immunotherapy for cancer.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore the relation between p53 protein expression and chemosensitivity to cisplatin in patients with non-small cell lung cancer (NSCLC).</p><p><b>METHODS</b>The DerSimonian-Laird random effect model was used to analyze the data reported in relevant literature.</p><p><b>RESULTS</b>Sixteen trials involving 1070 patients were retrieved. The overall positivity rate of p53 was 50.4% and overall response rate to cisplatin was 38.7%. The test for heterogeneity showed that all eligible studies had heterogeneity (chi 2-/+47.57, P<0.0001). The combined odds ratio (OR) was 1.37, with 95% confidence interval of 0.84-2.24.</p><p><b>CONCLUSION</b>Expression of p53 protein in patients with NSCLC is not associated with the chemosensitivity to cisplatin.</p>
