OBJECTIVE: Prenatal phthalate exposure has been associated with placental inflammatory factors and infant allergic rhinitis (AR). However, the results are inconclusive. We designed a population-based cohort study to examine the effects of placental inflammatory biomarkers on the sex-dependent associations between maternal phthalate exposure and infant AR. METHODS: A total of 2,348 pregnant women from Ma'anshan, Anhui Province, China, who were screened before antenatal visits and met the inclusion criteria, were included in the present study. We assessed AR in their offspring aged 36 months with a questionnaire. Quantitative PCR was performed to measure placental inflammatory factor mRNAs. The independent samples t-test and multivariable logistic regression were used to determine the associations between infant AR and maternal phthalates. RESULTS: Childhood AR may be related to education and family monthly income ( P = 0.01). The phthalate metabolites, mono (2-ethylhexyl) phthalate (MEHP), mono (2-ethyl-5-hydroxyl) phthalate (MEHHP), in pregnant women were associated with a significantly increased risk for infant AR in males [ P < 0.05; odds ratio ( OR): 1.285; 95% confidence interval ( CI): 1.037-1.591, and OR: 1.232, 95% CI: 1.008-1.507, respectively], but not females. Additionally, irritably-increased expression levels of HO-1 and IL-4 were associated with AR in male infants ( OR: 1.175; 95% CI: 1.038-1.329 and OR: 1.181; 95% CI: 1.056-1.322, respectively). The association between maternal urinary MEHHP and placental HO-1 was marginally significant according to mediation analysis. CONCLUSION The associations of maternal MEHHP and MEOHP levels with fetal AR in males were significant. Placental HO-1 was a fractional mediator in the associations between MEHHP and AR. Thus, the placenta should be further investigated as a potential mediator of maternal exposure-induced disease risk in children.

OBJECTIVE: To investigate the efficacy of self-made arthroscopic single channel in the treatment of carpal tunnel syndrome. METHODS: Sixty patients with primary carpal tunnel syndrome treated from January 2014 to December 2019 were divided into arthroscopic group and traditional open operation group. There were 30 cases in arthroscopic group, including 12 males and 18 females, aged (47.5±4.5) years and the course of disease was (6.6±4.2) months. There were 30 cases in the traditional operation group, including 10 males and 20 females, aged (48.5±3.5) years, and the course of disease was (5.6±4.4) months. Both groups were unilateral. According to the anatomy of wrist joint and the characteristics of transverse carpal ligament and arthroscopy, the instruments including cannula, inner heart and hook knife were designed. The patients in two groups were treated with decompression of transverse carpal ligament using arthroscopy combined with self-made instruments and traditional open sergery. The incision length, operation time, intraoperative bleeding, hospitalization cost, hospitalization time and recovery time of the two groups were observed and compared. Boston Carpal Tunnel Questionnaire (BCTQ) score was used to evaluate the clinical efficacy of arthroscopy combined with self made instruments in the treatment of carpal tunnel syndrome. RESULTS: Compared with the traditional group, the arthroscopic group had significant advantages in incision length, operation time, intraoperative bleeding and hospital stay, but the total cost of hospitalization was increased. The Boston score was significantly higher in the arthroscopic group than that in the traditional group at 1 month after operation, but not at 3 and 6 months after operation. CONCLUSION Arthroscopy combined with self-made instruments in the treatment of carpal tunnel syndrome is more reliable, minimally invasive and simplified than open surgery, but the patients should be clearly diagnosed and appropriately selected before operation to achieve satisfactory clinical effect.

OBJECTIVE: To compare the clinical efficacy of total arthroscopic surgery and traditional surgery for popliteal cyst. METHODS: From August 2014 to July 2017, 60 cases of popliteal cyst were treated with total arthroscopy or traditional surgery respectively. In total arthroscopy group, there were 30 patients including 7 males and 23 females with an average age of (55.81±8.53) years old; the duration of the disease was (3.52±1.12) years;according to Rauschning-Lingdgren grading, 7 cases were grade I, 19 cases were grade II, 4 cases were grade III. In traditional surgical group, there were 30 patients including 5 males and 25 females with an average age of (57.93±9.84) years old; the duration of the disease was (3.48±1.34) years; according to Rauschning-Lingdgren grading, 5 cases were grade I, 21 cases were grade II, 4 cases were grade III. Preoperative symptoms involved such as arthralgia and swelling after knee joint and limited mobility. MRI confirmed a popliteal cyst. Arthroscopic surgery and traditional surgical was used respectively. Incision length, operation time, average stay, total hospital cost and Lysholm score of two groups were compared. RESULTS: In the total arthroscopic group, 1 case suffered from nerve injury, and all cases' incision healed well. In the traditional surgical group, there was 1 case of incision infection, 2 cases of poor healing, 1 case of nerve injury and 1 case of recurrence. All 60 cases were followed up for 6 to 30 months with an average of (13.3±6.5) months. After operation, the symptoms of knee joint arthralgia and swelling, discomfort were significantly improved in the two groups. There were statistically significant differences in incision length, operation time, average stay, total hospitalcost and Lysholm score 6 months after surgery(<0.05). CONCLUSIONS The total arthroscopic resection of popliteal cyst, via anterior approach to having a knee joint cavity exploration and treatment of meniscus and bursa, while combined with posteromedial approach for cyst excision would promise a minimal surgery and less pain for patients. Patients will have a rapider recovery, lower recurrence rate and less complication. The total arthroscopic resection easy to accepting for the patient and having a better clinical curative effect is obviously superior to the traditional surgery.

OBJECTIVE: To investigate the short term clinical efficacy of direct anterior approach(DAA) total hip arthroplasty for the treatment of ankylosing spondylitis with hip flexion deformity. METHODS: From September 2014 to June 2017, 15 cases of ankylosing spondylitis with flexion deformity of the hip were treated with total hip arthroplasty through DAA approach including 12 males(17 hips) and 3 females(4 hips) with an average age of 34.4 years old ranging from 21 to 57 years old. Harris score system was used before and after operation to evaluate hip function, total hip activity and visual analogue scale (VAS) were used to evaluate the clinical efficacy. RESULTS: All 15 patients were followed up for an average of 26.2 months. In the operation, 1 case of great trochanter avulsion was given wire binding, and 1 case of linear split of the femur were given by wire binding. There were no hematoma, nerve injury and deep vein thrombosis of lower extremity. No prosthesis loosening and sinking were observed in the follow-up of X-ray film after operation. There was no heterotopic ossification after operation. After operation, 18 hips pain were relieved completely, and 3 hips pain were found when walking, which all satisfied with the daily life self-care requirements. Harris hip score, total hip motion and VAS score at 1 week after operation were significantly different from those before operation(<0.05). There was no significant difference in the scores of HHS, total hip motion and VAS at 1, 6 months after operation(>0.05). At the final follow-up, the Harris score was 91.2±5.3, the total hip mobility was (217.1±29.7)°, and the postoperative VAS pain score was 1.2±0.5, which was significantly different from the preoperative score(<0.05). CONCLUSIONS DAA approach THA has good effect in treating AS hip nonfunctional ankylosis with less trauma, less pain and quick recovery. It has a good short term effect, which can effectively improve the quality of life of patients.

A randomized, double-blind, active parallel controlled trial will be conducted to include patients with acute upper respiratory infection and wind-warmth lung heat disease (heat in lung-wei pattern). Patients with serious bacterial infection (white blood cell count>1.2×1010, neutrophil>80%) will be excluded.so as to further identify Jinye Baidu Granule indications of Wind-warmth lung heat disease (heat in lung-wei pattern).According to the subjects of symptoms of fever and sore throats,Patients will be divided into three blocks： fever, swelling and sore throat, combined fever and swelling and sore throat. Subjects in three blocks will be divided into treatment group and control group with stratified blocked randomization. The treatment group will be treated with Jinye Baidu Granule, and the control group will be treated with Fufang Shuanghua granule. Primary outcome measure of patients with fever will be body temperature recovery time. Primary outcome measure of patients with swelling and sore throat will be throat symptom score. Primary outcome measures of patients combined with fever and swelling and sore throat will be body temperature recovery time and throat symptom score. Before and after all of the patients in the group were collected blood and urine routine, liver and renal function, electrocardiogram (ECG) data as the safety index while observing it adverse events. A total of 623 patients were included. Compared with control group,sore throat symptoms of patients with sore throat and pharyngeal symptoms total score have significantly different. so Jinny Baidu granule have a significant advantage in the treatment of sore throat. All of the experiments showed that the safety of the drug was good. Nausea, vomiting, stomach pain, diarrhea, digestive tract symptoms may occur only occasionally. We should pay attention to the changes when using in patients with spleen deficiency cold to avoid adverse reaction.
