Objective To improve the diagnosis accuracy and treatment quality of juxtaglomerular cell tumor.Methods The clinical data of 2 female patients(20 and 36 years,respectively)with juxtaglo- merular cell tumor were presented and discussed in combination with review of the literature,including the onset characteristics,imaging features,treatment,pathology and prognosis.Case 1 presented with hyperten- sion of 180/110 mm Hg.The laboratory examinations showed that in decubitus and standing position,the plasma rennin activity(PRA)was 3.2?g - L~(-1)?h~(-1)and 36.5?g?L~(-1)?h~(-1);angiotensinⅡwas 54.3 pg/ml and 183.5 pg/ml;aldosterone was 193.5 prnol/L and 489.4 pmol/L,respectively;serum kalium was 2.6 mmol/L.Case 2 presented with hypertension of 210/120 mm Hg.The laboratory examination results were as follows:in decubitus and standing position,PRA was 4.3?g?L~(-1)?h~(-1)and 37.0?g?L~(-1)?h~(-1);angio- teusinⅡwas 55.6 pg/ml and 200.4 pg/ml;aldosterone was 162.4 pmol/L and 506.3 pmol/L,respectively; serum kalium was 3.0 mmol/L.On CT scan,both cases had renal tumor,with the diameter of 3.0 cm and 3. 5 cm,respectively.Results Case 1 underwent laparoscopic partial nephrectomy.Case 2 who had artery stricture and severe functional injure of the right kidney underwent laparoscopic right nephrectomy.The oper- ative time was 3.0 h and 2.0 h,and the blood loss was 175 ml and 112 ml,respectively.There was no mor- tality or postoperative complication.In 1 or 2 postoperative weeks,Case 1 had blood pressure(BP)of 120/70 mm Hg;in deeubitus and standing position,PRA was 1.5?g ~ L~(-1)?b~(-1)and 12.8?g?L~(-1)?h~(-1);angio- tensinⅡwas 30.6 pg/ml and 97.5 pg/ml;aldosterone was 78.5 pmol/L and 192.2 pmol/L,respectively ;se- rum kalium was 4.2 mmol/L.Case 2 had BP of 125/75 mm Hg;in decubitus and standing position,PRA was 1.6?g.L~(-1)?h~(-1)and 12.3?g.L~(-1)?h(-1);angiotensinⅡwas 34.3 pg/ml and 83.5 pg/ml;aldoste- rone was 62.6 pmol/L and 292.5 pmol/L,respectively;serum kalium was 4.8 mmol/L.Pathology showed that the juxtaglomerular cell tumor had intact envelop.Light microscopically,the tumor was very much like a hemangiopericytoma,showing active proliferation and nuclear atypia.The immunohistochemical staining showed positive Vimentin,CD_(34)expression,and negative MSA,EMA,Bcl-2,?-SmA,AG/AG3,34?En, CD_(117),CD_(31),Iv glue,Ki-G~-(＜2%)expression.Ultrastructural changes of the nuclei and some organelles in the cytoplasm were observed under electron microscope.The conspicuous ultrastructural feature was the pres- ence of secretion granules and rhomboid-shaped,crystal-like structures in the dilated cisternae of rough endo- plasmic reticulum and vesicles of Golgi complex.The follow-up was 14 and 6 months,respectively;the renal function was normal and no tumor recurrence was found.Conelusions Juxtaglomerular cell tumor is a rare tumor which can produce renin.It is characterized by severe hypertension and low serum potassium.La- boratory examination results are helpful for the diagnosis:PRA and angiotensinⅡincrease obviously ;aldoste- rone is 1-10 times more than normal;serum kalium is commonly between 2.1-3.5 mmol/L.The definite diagnosis depends on clinical presentations,immunohistochemistry,light and electron microscopic examina- tions.Laparoscopie operation is the first choice of surgical treatment.

As a result of the complex anatomy in upper cervical spine, the operative treatment of axis neoplasms is always complicated. Although the procedure for the second cervical vertebra (C2) surgery had been described previously in diverse approaches and reconstruction forms, each has its own limitations and restrictions that usually result in less satisfactory conclusions. The purpose of this study was to evaluate the operation efficacy for axis tumors by using a combined anterior (retropharyngeal) cervical and posterior approach in achieving total resection of C2 and circumferential reconstruction. Eight consecutive C2 tumor patients with mean age of 47.6 years in our institute sequentially underwent vertebra resection and fixation through aforementioned approach from Jan. 2006 to Dec. 2010. No surgical mortality or severe morbidity occurred in our group. In terms of complications, 2 cases developed transient difficulty in swallowing liquids (one of them experienced dysphonia) and 1 developed cerebrospinal fluid leakage (CSFL) that was resolved later. During a mean follow-up period of 31.9 months, the visual analogue scale (VAS) and Japanese orthopedic association (JOA) score revealed that the pain level and neurological function in all patients were improved postoperatively, and there was no evidence of fixation failure and local recurrence. It is concluded that the anterior cervical retropharyngeal approach permits a visible exposure to facilitate the C2 vertebra resection and perform an effective anterior reconstruction at the same time. The custom-made mesh cage applied in our cases can be acted as a firm and convenient implant in circumferential fixation.

OBJECTIVE: To observe the clinical efficacy of acupuncture for prevention of moderate to severe seasonal allergic rhinitis. METHODS: A total of 105 patients with moderate to severe seasonal allergic rhinitis were randomly divided into an observation group (53 cases, 3 cases dropped off) and a control group (52 cases, 4 cases dropped off). The patients in the observation group were treated with acupuncture at Yintang (GV 24⁺), Yingxiang (LI 20), Hegu (LI 4), Zusanli (ST 36), Fengchi (GB 20), Feishu (BL 13), etc. 4 weeks before the seizure period, once every other day, 3 times a week for 4 weeks. The patients in the control group were not given any intervention before the seizure period. Emergency drugs can be given appropriately during the seizure period in both groups. After seizure period, the seizure rate was recorded in the two groups; before treatment and on week 1, 2, 4, 6 of seizure period after treatment, the rhinoconjunctivitis quality of life questionnaire (RQLQ) score and total nasal symptom score (TNSS) were observed in the two groups; the rescue medication score (RMS) was recorded on week 1-6 of seizure period in the two groups. RESULTS: The seizure rate of the observation group was 84.0% (42/50), which was lower than 100.0% (48/48) in the control group (P<0.05). After treatment, the scores of RQLQ and TNSS at each time point of seizure period were decreased compared with before treatment in the observation group (P<0.01), which were lower than the control group (P<0.01). The RMS score at each time point of seizure period in the observation group was lower than the control group (P<0.05, P<0.01). CONCLUSION Acupuncture can reduce the incidence of moderate to severe seasonal allergic rhinitis, relieve the symptoms, improve the quality of life and reduce the use of emergency drugs.

With three representative types of gynecological diseases (dysmenorrhea, pelvic inflammation, polycystic ovary syndrome) as examples, the application methods of meridian and acupoint diagnosis for gynecological diseases treated with acupuncture and moxibustion are discussed. During clinical diagnosis and treatment, it is recommended to examine the patient's leg segment along the three yin meridians of foot, aiming to explore the positive reactions of the meridians and acupoints (color, shape, skin temperature, sensory abnormalities, etc.). Acupuncture and moxibustion treatment at this positive reaction place can improve the clinical efficacy. Meridian and acupoint diagnosis could provide basis for meridian syndrome differentiation, thus guiding the selection of acupoint prescriptions; it is also helpful to clarify the deficiency, excess, cold and heat of the disease nature, thus guiding the selection of acupuncture and moxibustion methods. In addition, it is an auxiliary method to estimate the prognosis and outcome of the disease.

BACKGROUNDHypoparathyroidism-deafness-renal dysplasia (HDR) syndrome is an autosomal dominant disorder primarily caused by haploinsufficiency of GATA binding protein 3 (GATA3) gene mutations, and hearing loss is the most frequent phenotypic feature. This study aimed at identifying the causative gene mutation for a three-generation Chinese family with HDR syndrome and analyzing auditory phenotypes in all familial HDR syndrome cases.

METHODSThree affected family members underwent otologic examinations, biochemistry tests, and other clinical evaluations. Targeted genes capture combining next-generation sequencing was performed within the family. Sanger sequencing was used to confirm the causative mutation. The auditory phenotypes of all reported familial HDR syndrome cases analyzed were provided.

RESULTSIn Chinese family 7121, a heterozygous nonsense mutation c.826C>T (p.R276*) was identified in GATA3. All the three affected members suffered from sensorineural deafness and hypocalcemia; however, renal dysplasia only appeared in the youngest patient. Furthermore, an overview of thirty HDR syndrome families with corresponding GATA3 mutations revealed that hearing impairment occurred earlier in the younger generation in at least nine familial cases (30%) and two thirds of them were found to carry premature stop mutations.

CONCLUSIONSThis study highlights the phenotypic heterogeneity of HDR and points to a possible genetic anticipation in patients with HDR, which needs to be further investigated.
